All, I'm getting "java.lang.NullPointerException at org.apache.tomcat.service.JNIEndpointConnector.start(JNIEndpointConne ctor.java:110)" Question 1. Should uriworkermap.properties and uriworkermap.properties-auto be similar? uriworkermap.properties is set to use jni only and uriworkermap.properties-auto does not contain any reference to jni. It's default is ajp12. Question 2. For an NT installation, does the path separator matter in the conf files. e.g. in server.xml there is path="logs/tomcat.log" and <Connector className="org.apache.tomcat.service.JNIEndpointConnector"> <Parameter name="native_lib" value="e:\jakarta\tomcat-3.2.1\bin\win32\i386\jni_connect.dll"/> </Connector> Question 3. The jni_connect.dll appears to be failing to load with a java.lang.NullPointerException. Any Ideas?
