You could try to do this, though break EJB spec:
remoteMethod() {
LoadNativeLibAction action = new LoadNativeLibAction("SWEOJNI");
AccessController.doPrivileged(action);
}
private static class LoadNativeLibAction implements PrivilegedAction {
String nativeLibName = null;
public LoadNativeAction(String nativeLibName) {
this.nativeLibName = nativeLibName;
}
public Object run() {
try {
System.loadLibrary(nativeLibName);
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
}
Good luck.

Subject: Re: how to load native library to ejb container
Actually, I want to use a third party java library that wraps native c++
library in a session bean.
I used it in servlets that deployed in IBM Websphere Application Server
3.5.3.
In the servlet, I used System.loadLibrary("SWEOJNI"). It works.
I search it online. Somebody suggested the permession in server.policy file
can be changed to loadLibrary.
I tried a couple of times. It failed because I don't know how?
Any suggestion?
Jim

To do it in session bean is not allowed by EJB spec.

Subject: how to load native library to ejb container
In a stateless session bean, I need to load native library by using
System.loadLibrary("SWEOJNI") in setSessionContext. I got the following
error:
Could not create stateless EJB: java.security.AccessControlException: access
denied (java.lang.RuntimePermission loadLibrary.SWEOJNI) at
com.sun.ejb.containers.StatelessSessionContainer.createStatelessEJB(Stateles
sSessionContainer.java:358)

at
fsu.ais.jstew.ejb.ItemListGatewayBean_EJBObjectImpl.prepareForLogin(ItemList
GatewayBean_EJBObjectImpl.java:230)
------------------------------------------
How do I set up permission to allow container to load native libraries? Any
help is highly appriciated.
