Default error page generation logic in tomcat
Hi Guys,
I had a specific requirement related to tomcat error generation. When a
default error page is generated like 404 error page, tomcat appends its
version info at the bottom of the page. I don't want this version to be
displayed on the error page. I am trying to understand which part of the
tomcat code actually does this?
Any response will be appreciated.
Thanks,
Raghu

Ok... I just figured out a work around for this to make work. I modified
ServerInfo.properties from catalina.jar and re-jarred it and overrode the
original catalina.jar. This seems to work. but, I am just curious whether
this has any side effects? Earlier, I tried doing the same thing but, was
not actually overriding catalina.jar proprely.
Thanks,
Raghu

A red flag just went up. Are you using a real Tomcat, or a 3rd-party repackaged version? If the latter, it probably has scattered Tomcat files all over the place, and will be prone to numerous errors and stability issues. Suggest removing the Tomcat you have and downloading a real one from http://tomcat.apache.org.

Mark,
Appreciate your response. I have this tomcat running on linux and I don't
find catalina.properties any where in the tomcat folders. so, I tried
unzipping this catalina.jar and changed the ServerInfo.Properties and zipped
into catalina.jar. but, still I see that version info on an error.
Do you know whether catalina.properties and catalina.policy ( which I could
find in my linux) or same?
Unzipping, modifying and zipping back - should this solve the problem?
Thanks,
Raghu

It is the ErrorReportValve and it gets the information from
org.apache.catalina.util.ServerInfo
You can over-ride this by:
1. extract org/apache/catalina/util/ServerInfo.properties from catalina.jar
and put that file in
${CATALINA_HOME}/classes/org/apache/catalina/util/ServerInfo.properties
2. Edit ${CATALINA_HOME}/conf/catalina.properties and change
common.loader=${catalina.home}/lib,${catalina.home}/lib/*.jar
to
common.loader=${catalina.home}/classes,${catalina.home}/lib,${catalina.home}/lib/*.jar
Any values you put in
${CATALINA_HOME}/classes/org/apache/catalina/util/ServerInfo.properties
will be used when reporting server name, version etc.
HTH,
Mark

Create your own 404 error page and add it to your web.xml.
<error-page>
<error-code>404</error-code>
<location>/error/404.jsp</location>
</error-page>
−
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/error/500.jsp</location>
</error-page>
−
<error-page>
<error-code>500</error-code>
<location>/error/500.jsp</location>
</error-page>
