problem in JavaMethod classloader

Hi,
When I executing my custom method (on a javamethod server) I received next exception:
java.lang.IllegalArgumentException: Interface ru.custom.IMyInterface is not visible from class loader
at java.lang.reflect.Proxy$ProxyClassFactory.apply(Proxy.java:581)
at java.lang.reflect.Proxy$ProxyClassFactory.apply(Proxy.java:557)
at java.lang.reflect.WeakCache$Factory.get(WeakCache.java:230)
at java.lang.reflect.WeakCache.get(WeakCache.java:127)
at java.lang.reflect.Proxy.getProxyClass0(Proxy.java:419)
at java.lang.reflect.Proxy.newProxyInstance(Proxy.java:719)

I'am understand that this happens when the interface you are trying to proxy is in a library loaded through two different classloaders but I'am not understand how to resolve this. Maybe someone has encountered such a problem?

What exactly is your interface ? Is it part of a TBO or SBO or module ? How do you deploy it (e.g. packaged in a DAR in the docbase or do you copy the jar file to the JMS and if so where ? How do you call it ?

My interface its a part of TBO module. This is jar file is copy to java_methods(standartd fodler in documentum) folder.

You could try to put it under ServerApps.ear/lib or ServerApps.ear/DmMethods.war/WEB-INF/lib even though it's not so clean (beware of upgrades). However, it is best practice to package TBOs in a DAR and deploy it to the docbase. This should solve your classpath issue.

If you are using java module, then you should be importing your JAR files into repository, so that the TBO module (and JAR) is deployed dynamically.

In my long expirience working with many project with documentum, it's crazy customization everywhere, and we have no module(dmc_module in this project) so in my case the solution was moved my interace to ServerApps.ear/DmMethods.war/WEB-INF/lib and its worked! Thanks guys so much!
