Hi,
I'm using tomcat apache-tomcat-6.0.37
I have a few web applications in webapps directory.
portal
sms
crm
I'm creating custom error pages.
inside the webapplication "portal" under WEB-INF in web.xml I have given
the following.
<error-page>
<error-code>400</error-code>
<location>/lp/404.html</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/lp/404.html</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/lp/oops.html</location>
</error-page>
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/lp/oops.html</location>
</error-page>
And is working fine for the errors like
domain.com/portal/sdgggdhsh
But for other web applications, obviously it wont work. because I haven't
configured in their web.xml files.
Is there any way I can give common error pages?
I can see that there is a web.xml file under conf directory. And I have
given the settings in it. As below.
<error-page>
<error-code>400</error-code>
<location>/404.html</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/404.html</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/oops.html</location>
</error-page>
<error-page>
<exception-type>java.lang.Throwable</exception-type>
<location>/oops.html</location>
</error-page>
Path I changed. starting from "/" and put the files in webapps directory.
But it is not working.
How can I do this?
After a search in Google for "tomcat error-page location", I found this :
http://stackoverflow.com/questions/3856145/empty-page-instead-of-custom-tomcat-error-page
which seems to say that Tomcat will always prefix the given <location> with the
context path of the application where the error happens.
(For example, if you have <location>/oops.html</location, and if the error happens in your
app "/MyApp", then Tomcat will be looking for the file ...webapps/MyApp/oops.html).
So you cannot have one "generic" location for these error pages, and share them for all
applications. You have to add the error page to each deployed application, separately.
More precisely : you can *define* the error pages, as you have done, in the generic
conf/web.xml. But you still have to put a copy of the pages themselves in each
application separately.
I suppose that this obeys the general principle according to which each application should
be self-contained.
Maybe in later Tomcat versions, there would be a way around this via aliases or the likes,
but it is probably still not recommended.
Note also, separately : the URL path "/" resolves to ".../webapps/ROOT/", not to
".../webapps/".
