Spring boot remote Websphere EJB call

Question

I have Websphere thin client jars in my classpath and a sample spring boot application. I am unable to make remote ejb call because it is throwing corab exception. I am using oracle jdk1.8 to make websphere ejb call

The above log shows the corba errors generated by ibm jar files.

java.lang.ClassNotFoundException: com.ibm.ws.wlm.client.WLMClient

Looks like this is the class you're missing.

You'll need to add the com.ibm.ws.wlm.jar to your class path.

I verified and the required jar files are in the classpath – Sharad Goyal Aug 16 '17 at 17:11
Take a look at the answers here: https://stackoverflow.com/questions/6322107/java-no-security-manager-rmi-class-loader-disabled It's likely you have access to com.ibm.ws.wlm.jar on one side of the Server/Client equation, but not the other. – mswatosh Aug 16 '17 at 18:43
