    Failed to aspectize class

      Hi all,

      I am using JBossCache as hibernate's 2nd level cache for my application. Actually I am trying to use TreeCacheAOP, but without success.

      I am using the JBossAOP class loader (-Djava.system.class.loader=org.jboss.aop.standalone.SystemClassLoader) to make the AOP magic, but the application fails while trying to aspectize some classes that I thought would not be touched.

      The error message is:
      [error] Failed to aspectize class oracle.sql.converter.CharacterConverterFactoryOGS. Could not find class it references oracle.i18n.text.converter.CharacterConverterOGS.. Do verbose mode if you want full stack trace.
      java.lang.Error: Error transforming the class oracle.sql.converter.CharacterConverterFactoryOGS: org.jboss.aop.instrument.TransformationException: Failed to aspectize class oracle.sql.converter.CharacterConverterFactoryOGS. Could not find class it references oracle.i18n.text.converter.CharacterConverterOGS
      at org.jboss.aop.standalone.SystemClassLoader.loadClass(SystemClassLoader.java:191)
      at java.lang.ClassLoader.loadClass(ClassLoader.java:235)

      at java.lang.Class.forName(Class.java:141)
      at net.sf.hibernate.connection.DBCPConnectionProvider.configure(DBCPConnectionProvider.java:64)

      Now I don't know what to do. I would like a lot to use TreeCacheAOP, because it seems to be significantly faster than TreeCache for my cluster enviroment.

      I don't know if it is possible, but can I make jboss-aop only play with the classes whose instances will be cached, or it has to aspectize every class that the classloader loads? Sorry if this is a silly question, but I am a begginer with either JBossCache, JBossAOP and AOP in general and I couldn't find much help in the documentation.

      I'm not running JBoss server, but i think that all needed jars are in the JARs in classpath:

      hibernate2.jar
      jboss-cache.jar
      jboss-common.jar
      jboss-jmx.jar
      jboss-system.jar
      concurrent.jar
      jboss-remoting.jar
      log4j.jar
      jboss-minimal.jar
      jboss-aop.jar
      javassist.jar
      trove.jar

      All these jars came with hibernate 2.1.6 or with jboss-cache 1.2.

      Thanks in advance,
