UnsatisfiedLinkError Applet --> EJB

[Nick Stone]

Hello,

I�m using WSAD 5 for Developing an Application which consists of an EJB-Module and a Web-Module. The whole Application is deployed to the WSAD-internal Server WAS 5.1.

The Web-Modul consists of a HTML-File which calls an Applet. The Applet trys to connect to an EJB on the Server. The problem: an UnsatisfiedLinkError appears in the Client console.

System.out.println("Context Provider URL:" +props.getProperty(Context.PROVIDER_URL));
props.put(InitialContext.INITIAL_CONTEXT_FACTORY,

System.out.println("Factory gesetzt!");
props.put(InitialContext.URL_PKG_PREFIXES,
"com.ibm.ws.naming");

Please look at the other topic.

UnsatisfiedLinkErrors are usually caused when a native library has already been loaded by one ClassLoader and a different ClassLoader attempts to load it again. When we moved from WAS 4.x to 5.x we went thru a long pain period with ClassLoader issues. Try adjusting your ClassLoader policies until it works and then you should get a rough idea of which ClassLoader is causing the problem.
