i have a software which runs on jboss and it requires crypto library which resides in jre/lib/ext. I get the following exception:
Caused by: java.lang.ClassNotFoundException: com.sun.crypto.provider.SunJCE from [Module "deployment.myatrium-intranet-ear.ear.myatrium_intranet.jar:main" from Service Module Loader]
at org.jboss.modules.ModuleClassLoader.findClass(ModuleClassLoader.java:190)

i have tried the following solution in this link:
but failed to get ext folder scanned.
Really in a desperate situation. A help is really appreciated.
thanks in advance
Solução
I had a very similar problem a few months ago and it seems that the standard approach is not working.
This link solved my problem: https://community.jboss.org/thread/175395
It talks about the bouncycastle provider, but should work for sunjce_provider too.
Outras dicas
You have understand it wrong. JBoss 7 have migrated to full OSGi. You need to add them to boot delegations .
It indeed loads the ext in classpath. The problem is it applies a class filter (to prevent you use non-standard class).
The same problem occur if you use the ODBC driver (sun.jdbc.odbc.*) and other sun.* classes. You have to add it to boot delegration / system package. (this is not the proper way. But you seems to hate the proper way, so....)
See these pages for details:
Try putting the following:
Extension-List: crypto
crypto-Extension-Name: javax.crypto
inside the WAR/classes/META-INF/MANIFEST.MF
Usually in a war file the META-INF is inside the root of the war as in
WAR
├── WEB-INF
│ └── classes
└── META-INF
└── MANIFEST.MF
The following seems to work for liferay 6.1 on jboss 7.1.1
WAR
└── WEB-INF
└── classes
└── META-INF
└── MANIFEST.MF
it will work in Jboss 7, by just pointing to the jar, either using jboss-deployment-strcuture.xml or manifest entry.
