If you use IBM’s WebSphere plugin for eclipse you might have the problem that other plugins can’t establish an SSL connection anymore. The result is most times a ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory. This blog explains the reason behind the problem and gives a workaround to prevent that exception. Problem description When a component within eclipse (e.g. atlassian jira connector) tries to connect to an SSL socket a ClassNotFoundException: com.ibm.websphere.ssl.protocol.SSLSocketFactory is thrown. This exception is often the root cause of other exceptions.

Some time ago I stumbled on a weird exception when deploying an EAR on IBM WebSphere Application Server 8.5. The EAR got successfully installed, but when the application server tried to start the WAR archive of my EAR I got this exception: javax.naming.ConfigurationException: NamingManager.getURLContext cannot find the factory for this scheme: java at com.ibm.ws.naming.util.Helpers.checkForUrlContext(Helpers.java:1631) at com.ibm.ws.naming.util.WsnInitCtx.lookup(WsnInitCtx.java:160) at com.ibm.ws.naming.util.WsnInitCtx.lookup(WsnInitCtx.java:179) at org.apache.aries.jndi.DelegateContext.lookup(DelegateContext.java:161) at javax.naming.InitialContext.lookup(InitialContext.java:436) After searching the web for this exception I came to the conclusion that I have to debug it on my own.
