    JBossAOP and static inner class loading

    Danai W. Newbie

      Hi All,

      I am unsuccessful in using JBossAOP1.1.2 to load static inner class. Below is a part of the error message:

      [Loaded org.bouncycastle.jce.provider.JCEBlockCipher]
      [Loaded org.bouncycastle.jce.provider.JCEBlockCipher$DESede]
      org.apache.ws.security.WSSecurityException: An unsupported signature or encryption algorithm was used; nested exception is:
       org.apache.xml.security.encryption.XMLEncryptionException: Cannot find any provider supporting DESede/CBC/ISO10126Padding

      If I run, "java -verbose -Djava.system.class.loader=org.jboss.aop.standalone.SystemClassLoader MyClass", I will get the error message as shown above.
      But if I run "java -verbose MyClass", everything works fine.

      I also verified that the inner class (JCEBlockCipher$DESede) is in the same jar as its outer class (JCEBlockCipher), and the jar is in the classpath.

      Here is the JCEBlockCipher snippet source code:
      package org.bouncycastle.jce.provider;
      public class JCEBlockCipher extends WrapCipherSpi
       implements PBE
       // hiding outer class implementation
       * DESede
       static public class DESede
       extends JCEBlockCipher
       public DESede()
       super(new DESedeEngine());
       }// end inner class

      (For the complete source code, please download http://www.bouncycastle.org/download/jce-jdk13-127.zip.)

      It seems to me that JBossAOP fails to load static inner class. Is there any way to work around this problem?

      I truely appreciate any comments and suggestions.

          For more information, I'm using jdk1.4.2_06-b03.
          Also I believe that the class DESedeEngine and its related classes are already in the system classpath.

            I run the following:

            java org.jboss.aop.hook.GenerateInstrumentedClassLoader C:\testaop

            Then I got C:\testaop\java\lang\ClassLoader.class

            Then I run (with all required already in classpath)
            java -Xbootclasspath/p:C:\testaop\java\lang\ClassLoader com.bar.MyClass

            I still got the same error. However, it seems to me that jdk5+jbossaop for jdk5 solve the error. It works fine as it's expected to be. I'd, at this time, move to jdk5.

            Kabir, Thank you very much for your suggestion.

              However for JDK 1.4 your command line should be

              java -Xbootclasspath/p:C:\testaop com.bar.MyClass

              i.e. C:\testaop contains the java\lang\ directory structure.

              Also, make sure that C:\testaop is not the directory where your main classes are (otherwise they get added to the bootclasspath too)

                I have tried

                java -Xbootclasspath/p:C:\testaop com.bar.MyClass

                as well. But I got the error msg below:
                Exception in thread "main" java.lang.NoClassDefFoundError: org/jboss/aop/AspectManager

                 at java.lang.ClassLoader.loadClass(Unknown Source)
                 at java.lang.ClassLoader.loadClassInternal(Unknown Source)

                I believe that jboss-aop.jar is in the classpath. (I set it in both window environment and script environment.) I have no idea why it could not find org/jboss/aop/AspectManager.
