Problem running tomcat with Apache

[Luis Lu�vano]

Hi:       I have an issue running tomcat with Apache. Tomcat itself works fine, but with Apache only the servlets examples don't work (and any servlet). The following error occur:   Error: 500   Location: /examples/servlet/HelloWorldExample   Internal Servlet Error:   java.lang.NullPointerException         at java.util.Hashtable.get(Hashtable.java:320)         at org.apache.tomcat.request.SimpleMapper.getPathMatch(SimpleMapper.java:352)         at org.apache.tomcat.request.SimpleMapper.findContainer(SimpleMapper.java:239)         at org.apache.tomcat.request.SimpleMapper.requestMap(SimpleMapper.java:188)         at org.apache.tomcat.core.ContextManager.processRequest(ContextManager.java:594)         at org.apache.tomcat.core.ContextManager.service(ContextManager.java:552)         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:484)       I have a Win98 machine with Apache 1.3.12 and tomcat 3.1. I appreciate any help.   Thanks.       Luis Lu�vano
