I'm attempting to migrate from jserv to tomcat and everything appears to be working well, except for testing the status of the servers in my load balancing set. The status page appears (/jserv/status?module=xxx.domain) and I see the correct load balancing definitions. But if I poke the Test button for any of them, the page hangs and I see this exception in tomcat's output: HANDLER THREAD PROBLEM: java.lang.NullPointerException java.lang.NullPointerException at org.apache.tomcat.core.ContextManager.handleError(Compiled Code) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:566) at org.apache.tomcat.service.connector.Ajp12ConnectionHandler.processConnection(Ajp12ConnectionHandler.java:156) at org.apache.tomcat.service.TcpConnectionThread.run(SimpleTcpEndpoint.java:338) at java.lang.Thread.run(Thread.java:479) I can change the state via this page and the load balancing appears to be distributing requests. I just can't get the test to work. Has anyone else had this problem? Tomcat 3.1, Solaris 2.6, JDK 1.2.2_05, Apache 1.3.9 and mod_jserv from both JServ 1.1 and tomcat 3.1.
