Encrypted class loading with jboss 5.1

[irbash]

Hello All,

We are using jboss 5.1 to deploy our application. Now we want to secure our .class files, so we are trying to encrypt the .class files.

but once we use encrypted .class files, jboss throws error (rather warnings saying

WARN  [org.jboss.detailed.classloader.ClassLoaderManager] (main) Unexpected error during load of:xxx.xxx.UserController

java.lang.ClassFormatError: Unknown constant tag 80 in class file xxx/xxx/UserController)

Can some one tell me how I can add a custom class loader to jboss 5.1 which can decrypt the .class files before loading it.

Thanks,

Irfan
