Hi, Apache-Tomcat warriors! I have one web-server (Apache2) ; one app-server (Tomcat4.0.4) ; and one database-server. I am trying to get the browser to open an HTTP connection to Apache and tunnel the request to Tomcat to get some data from the database server. Todate, it has been a frustrating experience, and I am getting this "500 for URL". Searching the web, I find this cryptic description : Internal Error 500: The server encountered an unexpected condition which prevented it from fulfilling the request. The output in $CATALINA_HOME/logs/caco_access_log.2002-10-15.txt is also very crytic eg 192.168.0.2 --[15/Oct/2002:18:36:57 10000] "POST /com/RemoteLiteHelperServer HTTP/1.1" 500 3385 ** By the way, if I do not "tunnel" and use the straightforward http://localhost/com/AllEmployees, it works well. The "500 for URL" arises only when I embed the .HTML in the web page and start the applet from the web page. ** Fresh out of ideas for today... so please help :-( TIA
