"javap jar:file:" - Specify Bytecode in JAR
How to specify Bytecode in a JAR file for the "javap" command?
✍: FYIcenter
If the bytecode is stored in *.class file,
you can specify the bytecode for the "javap" command using the
class file path name directly.
For example:
> javap HelloWorldFrame.class > javap \Users\fyicenter\HelloWorldFrame.class
If the bytecode is stored in *.jar file, you can specify the bytecode for the "javap" command using the "jar:file:" syntax:
> javap 'jar:file://absolute_path!/class_path' > javap 'jar:file:relative_path!/class_path'
1. Compile HelloWorldFrame.java used in the last tutorial into a bytecode file, HelloWorldFrame.class:
> javac HelloWorldFrame.java
2. Build a *.jar file with source code and bytecode:
> jar --create --file hello.jar HelloWorldFrame*.* > jar --list --file hello.jar META-INF/ META-INF/MANIFEST.MF HelloWorldFrame$1.class HelloWorldFrame.class HelloWorldFrame.java
3. Run "javap" command on a bytecode in the *.jar file:
> javap 'jar:file:./hello.jar!/HelloWorldFrame.class' Compiled from "HelloWorldFrame.java" public class HelloWorldFrame extends javax.swing.JFrame { java.lang.String message; public HelloWorldFrame(); public static void main(java.lang.String[]); } > javap 'jar:file:///Users/fyicenter/hello.jar!/HelloWorldFrame.class' Compiled from "HelloWorldFrame.java" public class HelloWorldFrame extends javax.swing.JFrame { java.lang.String message; public HelloWorldFrame(); public static void main(java.lang.String[]); }
