14<p>Javassist (JAVA programming ASSISTant) makes Java bytecode manipulation
15simple.  It is a class library for editing bytecodes in Java;
16it enables Java programs to define a new class at runtime and to
17modify a class file when the JVM loads it.  Unlike other similar
18bytecode editors, Javassist provides two levels of API: source level
19and bytecode level.  If the users use the source-level API, they can
20edit a class file without knowledge of the specifications of the Java
21bytecode.  The whole API is designed with only the vocabulary of the
22Java language.  You can even specify inserted bytecode in the form of
23source text; Javassist compiles it on the fly.  On the other hand, the
24bytecode-level API allows the users to directly edit a class file as
25other editors.

68<h2>How to run sample programs</h2>
69
70<p>JDK 1.4 or later is needed.
71
72<h3>0. If you have Apache Ant</h3>
73
74<p>Run the sample-all task.
75Otherwise, follow the instructions below.
76
77<h3>1. Move to the directory where this Readme.html file is located.</h3>
78
79<p>In the following instructions, we assume that the javassist.jar
80file is included in the class path.
81For example, the javac and java commands must receive
82the following <code>classpath</code> option:
83
84<ul><pre>
85-classpath ".:javassist.jar"
86</pre></ul>
87
88<p>If the operating system is Windows, the path
89separator must be not <code>:</code> (colon) but
90<code>;</code> (semicolon).  The java command can receive
91the <code>-cp</code> option
92as well as <code>-classpath</code>.
93
94<p>If you don't want to use the class-path option, you can make
95<code>javassist.jar</code> included in the <code>CLASSPATH</code>
96environment:
97
98<ul><pre>
99export CLASSPATH=.:javassist.jar
100</pre></ul>
101
102<p>or if the operating system is Windows:
103
104<ul><pre>
105set CLASSPATH=.;javassist.jar
106</pre></ul>
107
108
109<p>Otherwise, you can copy <tt>javassist.jar</tt> to the directory
110
111<ul>&lt;<i>java-home</i>&gt;<tt>/jre/lib/ext</tt>.</ul>
112
113<p>&lt;<i>java-home</i>&gt; depends on the system.  It is usually
114<tt>/usr/local/java</tt>, <tt>c:\j2sdk1.4\</tt>, etc.
115
116<h3>2. sample/Test.java</h3>
117
118<p>   This is a very simple program using Javassist.
119
120<p>   To run, type the commands:
121
122<ul><pre>
123% javac sample/Test.java
124% java sample.Test
125</pre></ul>
126
127<p>   For more details, see <a type="text/plain" href="sample/Test.java">sample/Test.java</a>
128
129<h3>3. sample/reflect/*.java</h3>
130
131<p>   This is the "verbose metaobject" example well known in reflective
132   programming.  This program dynamically attaches a metaobject to
133   a Person object.  The metaobject prints a message if a method
134   is called on the Person object.
135
136<p>   To run, type the commands:
137
138<ul><pre>
139% javac sample/reflect/*.java
140% java javassist.tools.reflect.Loader sample.reflect.Main Joe
141</pre></ul>
142
143<p>Compare this result with that of the regular execution without reflection:
144
145<ul><pre>% java sample.reflect.Person Joe</pre></ul>
146
147<p>   For more details, see <a type="text/plain" href="sample/reflect/Main.java">sample/reflect/Main.java</a>
148
149<p>   Furthermore, the Person class can be statically modified so that
150   all the Person objects become reflective without sample.reflect.Main.
151   To do this, type the commands:
152
153<ul><pre>
154% java javassist.tools.reflect.Compiler sample.reflect.Person -m sample.reflect.VerboseMetaobj
155</pre></ul>
156
157<p>   Then,
158<ul><pre>
159% java sample.reflect.Person Joe
160</pre></ul>
161
162<h3>4. sample/duplicate/*.java</h3>
163
164<p>   This is another example of reflective programming.
165
166<p>   To run, type the commands:
167
168<ul><pre>
169% javac sample/duplicate/*.java
170% java sample.duplicate.Main
171</pre></ul>
172
173<p>Compare this result with that of the regular execution without reflection:
174
175<ul><pre>% java sample.duplicate.Viewer</pre></ul>
176
177<p>For more details, see
178<a type="text/plain" href="sample/duplicate/Main.java">sample/duplicate/Main.java</a>
179
180<h3>5. sample/vector/*.java</h3>
181
182<p>This example shows the use of Javassit for producing a class representing
183a vector of a given type at compile time.
184
185<p>   To run, type the commands:
186<ul><pre>
187% javac sample/vector/*.java
188% java sample.preproc.Compiler sample/vector/Test.j
189% javac sample/vector/Test.java
190% java sample.vector.Test
191</pre></ul>
192
193<p>Note: <code>javassist.jar</code> is unnecessary to compile and execute
194<code>sample/vector/Test.java</code>.
195
196For more details, see
197<a type="text/plain" href="sample/vector/Test.j">sample/vector/Test.j</a>
198and <a type="text/plain" href="sample/vector/VectorAssistant.java">sample/vector/VectorAssistant.java</a>
199
200<h3>6. sample/rmi/*.java</h3>
201
202<p>   This demonstrates the javassist.rmi package.
203
204<p>   To run, type the commands:
205<ul><pre>
206% javac sample/rmi/*.java
207% java sample.rmi.Counter 5001
208</pre></ul>
209
210<p>   The second line starts a web server listening to port 5001.
211
212<p>   Then, open <a href="sample/rmi/webdemo.html">sample/rmi/webdemo.html</a>
213with a web browser running
214   on the local host.  (<tt>webdemo.html</tt> trys to fetch an applet from
215   <tt>http://localhost:5001/</tt>, which is the web server we started above.)
216
217<p>   Otherwise, run sample.rmi.CountApplet as an application:
218
219<ul><pre>
220% java javassist.web.Viewer localhost 5001 sample.rmi.CountApplet
221</pre></ul>
222
223<h3>7. sample/evolve/*.java</h3>
224
225<p>   This is a demonstration of the class evolution mechanism implemented
226   with Javassist.  This mechanism enables a Java program to reload an
227   existing class file under some restriction.
228
229<p>   To run, type the commands:
230<ul><pre>
231% javac sample/evolve/*.java
232% java sample.evolve.DemoLoader 5003
233</pre></ul>
234
235<p>   The second line starts a class loader DemoLoader, which runs a web
236   server DemoServer listening to port 5003.
237
238<p>   Then, open <a href="http://localhost:5003/demo.html">http://localhost:5003/demo.html</a> with a web browser running
239   on the local host.
240(Or, see <a href="sample/evolve/start.html">sample/evolve/start.html</a>.)
241
242<h3>8. sample/hotswap/*.java</h3>
243
244<p>This shows dynamic class reloading by the JPDA.  It needs JDK 1.4 or later.
245To run, first type the following commands:
246
247<ul><pre>
248% cd sample/hotswap
249% javac *.java
250% cd logging
251% javac *.java
252% cd ..
253</pre></ul>
254
255<p>If your Java is 1.4, then type:
256
257<ul><pre>
258% java -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8000 Test
259</pre></ul>
260
261<p>If you are using Java 5, then type:
262
263<ul><pre>
264% java -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=8000 Test
265</pre></ul>
266
267<p>Note that the class path must include <code>JAVA_HOME/lib/tools.jar</code>.
268
269<h2>Hints</h2>
270
271<p>To know the version number, type this command:
272
273<ul><pre>
274% java -jar javassist.jar
275</pre></ul>
276
277<p>Javassist provides a class file viewer for debugging.  For more details,
278see javassist.Dump.

314<ul>
315	<li>ClassPool.makeClassIfNew(InputStream) was implemented.
316	<li>CtNewMethod.wrapped(..) and CtNewConstructor.wrapped(..)
317	implicitly append a method like _added_m$0.
318	This method now has a synthetic attribute.
319    <li>JIRA JASSIST-66 has been fixed.
320</ul>
321
322<p>-version 3.8.1 on July 17, 2008
323<ul>
324	<li>CtClass.rebuildClassFile() has been added.
325	<li>A few bugs of javassist.bytecode.analysis have been fixed.
326	3.8.0 could not correctly deal with one letter class name
327	such as I and J.
328</ul>
329
330<p>-version 3.8.0 on June 13, 2008
331<ul>
332    <li>javassist.bytecode.analysis was implemented.
333  	<li>JASSIST-45, 47, 51, 54-57, 60, 62 were fixed.
334</ul>
335
336<p>-version 3.7.1 on March 10, 2008
337<ul>
338    <li>a bug of javassist.util.proxy has been fixed.
339</ul>
340
341<p>-version 3.7 on January 20, 2008
342<ul>
343	<li>Several minor bugs have been fixed.
344</ul>
345
346<p>-version 3.6.0 on September 13, 2007
347
348<p>-version 3.6.0.CR1 on July 27, 2007
349
350<ul>
351    <li>The stack map table introduced since Java 6 has been supported.
352    <li>CtClass#getDeclaredBehaviors() now returns a class initializer
353        as well as methods and constructors.
354    <li>The default status of automatic pruning was made off.
355        Instead of pruning, this version of Javassist compresses
356        the data structure of a class file after toBytecode() is called.
357        The compressed class file is automatically decompressed when needed.
358        This saves memory space better than pruning.
359    <li><a href="http://jira.jboss.com/jira/browse/JASSIST-33">JIRA JASSIST-33</a> has been fixed.
360</ul>
361

365</ul>
366
367<p>-version 3.4 on November 17, 2006
368<ul>
369	<li>A bug in CodeConverter#replaceFieldRead() and CodeConverter#replaceFieldWrite()
370	was fixed. <a href="http://jira.jboss.com/jira/browse/JBAOP-284">JBAOP-284</a>.
371
372    <li>A synchronization bug and a performance bug in <code>javassist.util.proxy</code>
373    have been fixed
374    (<a href="http://jira.jboss.com/jira/browse/JASSIST-28">JASSIST-28</a>).
375    Now generated proxy classes are cached.  To turn the caching off,
376    set <code>ProxyFactory.useCache</code> to <code>false</code>.
377</ul>
378
379<p>-version 3.3 on August 17, 2006
380<ul>
381    <li>CtClass#toClass() and ClassPool#toClass() were modified to accept a
382    <code>ProtectionDomain</code>
383    (<a href="http://jira.jboss.com/jira/browse/JASSIST-23">JASSIST-23</a>).
384    Now ClassPool#toClass(CtClass, ClassLoader) should not be overridden.  All
385    subclasses of ClassPool must override toClass(CtClass, ClassLoader,
386    ProtectionDomain).
387
388    <li>CtClass#getAvailableAnnotations() etc. have been implemented.
389
390    <li>A bug related to a way of dealing with a bridge method was fixed
391    (<a href="http://jira.jboss.com/jira/browse/HIBERNATE-37">HIBERNATE-37</a>).
392
393    <li>javassist.scopedpool package was added.

397
398<ul>
399	<li>The behavior of CtBehavior#getParameterAnnotations() has been changed.
400	It is now compatible to Java Reflection API
401	(<a href="http://jira.jboss.com/jira/browse/JASSIST-19">JASSIST-19</a>).
402</ul>
403
404<p>- version 3.2.0.CR2 on May 9, 2006
405<ul>
406   <li>A bug of replace(String,ExprEditor) in javassist.expr.Expr has been fixed.
407  <li>Updated ProxyFactory getClassLoader to choose the javassit class loader
408   when the proxy superclass has a null class loader (a jdk/endorsed class)
409   (<a href='http://jira.jboss.com/jira/browse/JASSIST-18'>JASSIST-18</a>).
410  <li>Updated the throws clause of the javassist.util.proxy.MethodHandler
411   to be Throwable rather than Exception
412   (<a href='http://jira.jboss.com/jira/browse/JASSIST-16'>JASSIST-16</a>).
413</ul>
414
415<p>- version 3.2.0.CR1 on March 18, 2006

422
423<ul>
424  <li>getFields(), getMethods(), and getConstructors() in CtClass
425    were changed to return non-private memebers instead of only
426    public members.
427  <li>getEnclosingClass() in javassist.CtClass was renamed
428      to getEnclosingMethod().
429  <li>getModifiers() was extended to return Modifier.STATIC if the class
430      is a static inner class.
431  <li>The return type of CtClass.stopPruning() was changed from void
432    to boolean.
433  <li>toMethod() in javassist.CtConstructor has been implemented.

509  <li>CodeAttribute.computeMaxStack() has been added.
510</ul>
511
512<p>- version 2.6 in August, 2003.
513
514<ul>
515  <li>The behavior of CtClass.setSuperclass() was changed.
516      To obtain the previous behavior, call CtClass.replaceClassName().
517  <li>CtConstructor.setBody() now works for class initializers.
518  <li>CtNewMethod.delegator() now works for static methods.
519  <li>javassist.expr.Expr.indexOfBytecode() has been added.
520  <li>javassist.Loader has been modified so that getPackage() returns
521      a package object.
522  <li>Now, the compiler can correctly compile a try statement and an
523      infinite while-loop.
524</ul>
525
526<p>- version 2.5.1 in May, 2003.
527<br>Simple changes for integration with JBoss AOP
528<ul>
529  <li>Made ClassPool.get0 protected so that subclasses of ClassPool can call it.
530  <li>Moved all access to the class cache (the field ClassPool.classes) to a method called getCached(String classname).  This is so subclasses of ClassPool can override this behavior.
531</ul>
532
533<p>- version 2.5 in May, 2003.
534<br>From this version, Javassist is part of the JBoss project.
535<ul>
536  <li>The license was changed from MPL to MPL/LGPL dual.
537  <li>ClassPool.removeClassPath() and ClassPath.close() have been added.
538  <li>ClassPool.makeClass(InputStream) has been added.
539  <li>CtClass.makeClassInitializer() has been added.
540  <li>javassist.expr.Expr has been changed to a public class.
541  <li>javassist.expr.Handler has been added.
542  <li>javassist.expr.MethodCall.isSuper() has been added.
543  <li>CtMethod.isEmpty() and CtConstructor.isEmpty() have been added.
544  <li>LoaderClassPath has been implemented.
545</ul>
546
547<p>- version 2.4 in February, 2003.
548<ul>
549  <li>The compiler included in Javassist did not correctly work with
550	interface methods.  This bug was fixed.
551  <li>Now javassist.bytecode.Bytecode allows more than 255 local
552	variables in the same method.
553  <li>javassist.expr.Instanceof and Cast have been added.
554  <li>javassist.expr.{MethodCall,NewExpr,FieldAccess,Instanceof,Cast}.where()
555        have been added.  They return the caller-side method surrounding the
556	expression.
557  <li>javassist.expr.{MethodCall,NewExpr,FieldAccess,Instanceof,Cast}.mayThrow()
558        have been added.
559  <li>$class has been introduced.
560  <li>The parameters to replaceFieldRead(), replaceFieldWrite(),
561      and redirectFieldAccess() in javassist.CodeConverter are changed.
562  <li>The compiler could not correctly handle a try-catch statement.
563      This bug has been fixed.
564</ul>
565
566<p>- version 2.3 in December, 2002.
567<ul>
568  <li>The tutorial has been revised a bit.
569  <li>SerialVersionUID class was donated by Bob Lee.  Thanks.
570  <li>CtMethod.setBody() and CtConstructor.setBody() have been added.
571  <li>javassist.reflect.ClassMetaobject.useContextClassLoader has been added.
572  If true, the reflection package does not use Class.forName() but uses
573  a context class loader specified by the user.
574  <li>$sig and $type are now available.
575  <li>Bugs in Bytecode.write() and read() have been fixed.
576</ul>
577
578<p>- version 2.2 in October, 2002.
579<ul>
580  <li>The tutorial has been revised.
581  <li>A new package <code>javassist.expr</code> has been added.
582        This is replacement of classic <code>CodeConverter</code>.
583  <li>javassist.ConstParameter was changed into
584	javassist.CtMethod.ConstParameter.
585  <li>javassist.FieldInitializer was renamed into
586	javassist.CtField.Initializer.
587  <li>A bug in javassist.bytecode.Bytecode.addInvokeinterface() has been
588	fixed.
589  <li>In javassist.bytecode.Bytecode, addGetfield(), addGetstatic(),
590	addInvokespecial(), addInvokestatic(), addInvokevirtual(),
591	and addInvokeinterface()
592	have been modified to update the current statck depth.
593</ul>
594
595<p>- version 2.1 in July, 2002.
596<ul>
597  <li>javassist.CtMember and javassist.CtBehavior have been added.
598  <li>javassist.CtClass.toBytecode() has been added.
599  <li>javassist.CtClass.toClass() and javassist.ClassPool.writeAsClass()
600	has been added.
601  <li>javassist.ByteArrayClassPath has been added.
602  <li>javassist.bytecode.Mnemonic has been added.
603  <li>Several bugs have been fixed.
604</ul>
605
606<p>- version 2.0 (major update) in November, 2001.
607<ul>
608  <li>The javassist.bytecode package has been provided.  It is a
609    lower-level API for directly modifying a class file although
610    the users must have detailed knowledge of the Java bytecode.
611
612  <li>The mechanism for creating CtClass objects have been changed.
613
614  <li>javassist.tool.Dump moves to the javassist package.
615</ul>
616
617<p>version 1.0 in July, 2001.
618<ul>
619  <li>javassist.reflect.Metaobject and ClassMetaobject was changed.
620    Now they throw the same exception that they receive from a
621    base-level object.
622</ul>
623
624<p>- version 0.8
625<ul>
626  <li>javassist.tool.Dump was added.  It is a class file viewer.
627
628  <li>javassist.FiledInitializer.byNewArray() was added.  It is for
629    initializing a field with an array object.
630
631  <li>javassist.CodeConverter.redirectMethodCall() was added.
632
633  <li>javassist.Run was added.
634</ul>
635
636<p>- version 0.7
637<ul>
638  <li>javassit.Loader was largely modified.  javassist.UserLoader was
639    deleted.  Instead, Codebase was renamed to ClassPath
640    and UserClassPath was added.  Now programmers who want to
641    customize Loader must write a class implementing UserClassPath
642    instead of UserLoader.  This change is for sharing class search paths
643    between Loader and CtClass.CtClass(String).
644
645  <li>CtClass.addField(), addMethod(), addConstructor(), addWrapper() were
646    also largely modified so that it receives CtNewMethod, CtNewConstructor,
647    or CtNewField.  The static methods for creating these objects were
648    added to the API.
649
650  <li>Constructors are now represented by CtConstructor objects.
651    CtConstructor is a subclass of CtMethod.
652
653  <li>CtClass.getUserAttribute() was removed.  Use CtClass.getAttribute().
654
655  <li>javassist.rmi.RmiLoader was added.
656
657  <li>javassist.reflect.Metalevel._setMetaobject() was added.  Now
658    metaobjects can be replaced at runtime.
659</ul>
660
661<p>- version 0.6
662<ul>
663  <li>Javassist was modified to correctly deal with array types appearing
664    in signatures.
665
666  <li>A bug crashed resulting bytecode if a class includes a private static
667    filed.  It has been fixed.
668
669  <li>javassist.CtNewInterface was added.
670
671  <li>javassist.Loader.recordClass() was renamed into makeClass().
672
673  <li>javassist.UserLoader.loadClass() was changed to take the second
674    parameter.
675</ul>
676
677<p>- version 0.5
678<ul>
679  <li>a bug-fix version.
680</ul>
681
682<p>- version 0.4
683<ul>
684  <li>Major update again.  Many classes and methods were changed.
685    Most of methods taking java.lang.Class have been changed to
686    take javassist.CtClass.
687</ul>

689<p>- version 0.3
690<ul>
691  <li>Major update.  Many classes and methods were changed.
