Hello, I've installed Apache SOAP 2.2 under Apache Tomcat 3.2. I followed the installation instructions on the Apache SOAP homepage, and installed soap.jar, mail.jar and activation.jar in the server classpath. Apache Xerces is version 1.4.1, JDK is Sun's 1.1.8. I briefly tried the client side API, and it seems to work OK. After installing the Apache SOAP web archive, the admin client also seems to work OK. However, when I point my browser to the RPC router, I get an HTTP error 500 with the following details: --- Location: /soap/servlet/rpcrouter Internal Servlet Error: java.lang.NullPointerException at java.util.Hashtable.put(Hashtable.java) at org.apache.tomcat.core.Context.setAttribute(Context.java) at org.apache.tomcat.facade.ServletContextFacade.setAttribute(ServletContextFacade.java) at org.apache.soap.server.http.ServerHTTPUtils.setServletClassLoaderIntoContext(ServerHTTPUtils.java:144) at org.apache.soap.server.http.RPCRouterServlet.init(RPCRouterServlet.java:173) at javax.servlet.GenericServlet.init(GenericServlet.java) at org.apache.tomcat.core.ServletWrapper.doInit(ServletWrapper.java) at org.apache.tomcat.core.Handler.init(Handler.java) at org.apache.tomcat.core.ServletWrapper.init(ServletWrapper.java) at org.apache.tomcat.core.Handler.service(Handler.java) at org.apache.tomcat.core.ServletWrapper.service(ServletWrapper.java) at org.apache.tomcat.core.ContextManager.internalService(ContextManager.java) at org.apache.tomcat.core.ContextManager.service(ContextManager.java) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java) at org.apache.tomcat.service.TcpWorkerThread.runIt(PoolTcpEndpoint.java) at org.apache.tomcat.util.ThreadPool$ControlRunnable.run(ThreadPool.java) at java.lang.Thread.run(Thread.java) --- According to the documentation the router servlet should handle the GET request and return the following "Sorry, I don't speak via HTTP GET- you have to use HTTP POST to talk to me". Do any of you have any idea what could cause this? Currently I'm personally all out of ideas. -as
