Hello, and thanks to Ralph and others who tried to help me with this problem on the first go-round. I've got new information in my possession, and I'd like to try again.
To recap: Our environment Windows 2000 Server (sorry) with SP2 (we're moving to Linux, I promise!) Apache v1.3.23 Tomcat v3.3a (running as a NT service) Sun JDK 1.3.1_02 Our problem Occasionally, especially after editing a JSP file or files, Tomcat will suddenly fail to find the .java and .class files that go with a particular JSP. Looking in the "work" directory reveals that the files exist, but when we attempt to access that particular JSP thru Apache, we get 404 - File Not Found. The Apache error.log file gives no indication of a problem. The access.log file shows normal file access. Upon checking, we find the following sorts of entries in Tomcat's jvm.stderr file on the server: 2002-04-17 17:21:48 - Ctx(/CATS) : Class not found: TOMCAT/JSP/Math/Practice/MP6.jsp 2002-04-17 17:21:48 - Ctx(/CATS) : Status code:404 request:R( /CATS + /Math/Practice/MP6.jsp + null) msg:null 2002-04-17 17:21:50 - Ctx(/CATS) : Status code:404 request:R( /CATS + /Math/Practice/MP6.jsp + null) msg:null 2002-04-17 17:21:52 - Ctx(/CATS) : Status code:404 request:R( /CATS + /Math/Practice/MP6.jsp + null) msg:null We have had some success in causing this problem to go away by shutting down the Apache and Tomcat services, deleting the appropriate .java and .class (and .ver) files, restarting the Tomcat and Apache services, and hitting Reload on the browser. Sometimes (about 50% of the time) when we do this, Tomcat suddenly "finds" the files and the JSP runs, new .java and .class files are created, and we get the proper output. The remaining 50% of the time, it falls to one of two happenstances. Either (30%) we do the shutdown-services-and-delete routine followed by a reboot and the problem goes away, or (20%) we keep retrying on different clients until the problem suddenly vanishes. This problem is intermittent. Sometimes we'll get it with FOO.JSP but not BAR.JSP. We'll then take a corrective action (described above) and suddenly we'll get it with BAR.JSP but not FOO.JSP. Both JSP files are very similar, and there's nothing exotic about our coding. Sometimes the problem goes away with some waiting. This happens with both IE and Netscape clients, and with clients on different networks and behind different firewall/proxy situations, so we don't think that firewall, proxy or other network architecture issues are contributing factors. This happens to clients on the same LAN as the servers. Needless to say, we're quite perplexed, and don't understand what is going wrong. If anyone has any suggestions or recommendations, please respond.
