Hi,
I am trying to troubleshoot a GWT application that I have deployed to a tomcat
server (Apache Tomcat/7.0.55), running on a Bitnami stack (Ubuntu 14.04.1) at
AWS.
The initial web page loads just fine, but the first servlet RPC call I make
fails.
The servlet has various logging built in, it's the first thing the constructor
does, but even that is not occurring.
I looked in the tomcat logs, here is the only logging that is occurring (at
least that I can find) for the application:
/opt/bitnami/apache-tomcat/logs/localhost_access_log.2016-04-07.txt (ip address
obfuscated):
xxx.xx.xx.xxx - - [07/Apr/2016:09:48:58 -0400] "GET /Questionnaire/ HTTP/1.1"
200 2159
xxx.xx.xx.xxx - - [07/Apr/2016:09:48:59 -0400] "GET
/Questionnaire/questionnaire/questionnaire.nocache.js HTTP/1.1" 200 7455
xxx.xx.xx.xxx - - [07/Apr/2016:09:48:59 -0400] "GET
/Questionnaire/questionnaire/gwt/clean/clean.css HTTP/1.1" 200 29390
xxx.xx.xx.xxx - - [07/Apr/2016:09:49:00 -0400] "GET
/Questionnaire/questionnaire/DAB2DC6857E97DCA965B766CA77B6F8B.cache.js
HTTP/1.1" 200 139323
xxx.xx.xx.xxx - - [07/Apr/2016:09:49:00 -0400] "GET
/Questionnaire/questionnaire/gwt/clean/images/hborder.png HTTP/1.1" 200 1995
xxx.xx.xx.xxx - - [07/Apr/2016:09:49:21 -0400] "POST
/Questionnaire/questionnaire/rpc HTTP/1.1" 500 2972
So I can see that there is a "500" error occuring when the RPC call is made
(Internal Server Error).
I would expect more info to be in the catalina log, but there is nothing at all.
Other files in tomcat's logs directory are:
catalina-daemon.out
manager.2016-04-06.log
catalina.2016-04-06.log
localhost.2016-04-06.log
But none of the entries in them are from today.
Other GWT applications deployed to the same tomcat server are working just fine.
How should I go about troubleshooting this problem?
Surely tomcat must have a way of logging more detail on a 500 - Internal Server
Error?
