I am learning struts 1.0.2 with Apache 4.1.18.
In my webapp's web.xml I specified a resource properties file. This property file contains an index.title entry yet when I try to run the app in my IE browser I get a Http 500 error with the JasperException message "Missing message for key index.title"
While debugging I discoved that if I put an non-existant property file in my web.xml the Apache log still reports that the "application resources were loaded using" the non-existant property file. My property file is under yhe WEB-INF/classes/mypackage directory. Is this correct?
Can you suggest another area to investigate (I'm sure I don't have a typo).

If your web.xml says something like:
<init-param>
<param-name>application</param-name>
<param-value>ApplicationResources</param-value>
</init-param>
then your app will be looking for ApplicationResources.properties in "WEB-INF\classes".

I placed my source code in the default package. My web.xml specifies the resource property file as you described and my property file is in WEB-INF/classes. Still I have no luck finding my key value.
I inserted the <logic:notPresent> tag to test that my resources were in fact loaded ( tag code taken from the struts-example) and the test did not detect an error.
I could really use a tip on what I could test next to resolve this.

Can we see the code in your jsp as well as your properties file?

Try removing ".properties" from the end of "RegisterUserResources" in the above code.
Also, this is probably just a typo, and if you are running on a Windows platform it might not even matter (not sure to be honest), but in part of the code you showed you referenced a "registerUserResources.properties" however your web.xml refers to "RegisterUserResources" with a capital "R".

I may be wrong on this, but I believe the resource bundle is case sensitive. Check to make sure that the init-param in the web.xml file matches the case of the file name.

Thank you Jason!
I had to remove the .properties from the 'application' <param-value> in my web.xml
I will not forget this errorl. (nor will I have complete faith in tutorials on the web

)
