Check if you have JDK1.2 installed. For some reason Apache might look for this version of JDK to start -----Original Message----- From: Larry [mailto:larryhytail@xxxxxxxxx] Sent: Tuesday, March 25, 2003 10:53 AM To: java400-l@xxxxxxxxxxxx Subject: Tomcat & Apache on Three AS400's I have Tomcat 4.1.12 loaded on three AS400's teamed up with IBMs PTF distribution of Apache. I got Tomcat running on one as400 and then copied the tomcat directory to the other two AS400s. On the original install and the third install everuthig works great. But on the second install I can only get tomcat to work standalone. It absolutely refuses to function with the Apache plugin. When I install the apache-tomcat plugin module to the apache config, the Apache instance will not start. I have had my Sys Admin guy scour the three 400's for differences, but we can find none. PTF levels are the same. In one act of desparation we did a full backup of one of the working machines and restored it to the non-working machine and still ended up with the same result. I am left confounded. We called IBM support, but since we are using the Jakarta distribution of Tomcat they were less than helpful. Anyone have any ideas what I can look for? Any help appreciated. Some more details follow for those who are interested.

I also replaced workers.properties with a copy from one of the working machines with no result. So I do not believe it is a security issue. _______________________________________________ No banners.
