Multiple bundles broke my app(properties file)

[Timothy Sam]

Hi, I was experimenting with Struts internationalization. Before doing this, I had only a single bundle that was for displaying errors. Everything worked then. But when I added another bundle, for localization purpose my error messages aren't displayed anymore. Ok, I managed to make a fix for that by specifying the bundle parameter in my <html:error/> tag. But some parts of my app is completely broken especially those that used the <html:javascript/> tag. Here's an exception I'm getting and I think it's pretty weird...

HTTP Status 500 -

Yes, you can have multiple message files. There are some guidelines for doing so, however. Please read the "configuration" section of this link for more information.

In addition to the guidelines in the above link, here's one more:

Avoid usuing periods in your message resource name. Any periods indicate the package in which your resource bundle is being stored.

Thanks for the info! Anyway, everything works fine now except when I use javascript/client validation for Struts.


<html:errors bundle="errorMessageResources"/>

<html:javascript formName="applicantFormBean"/>


I dunno if this is any different from above since I've fixed most of the pages excep this one...

everything works fine again after removing the
<html:javascript formName="applicantFormBean"/> tag. But I need it to lessen the load on my server during validation. Thanks!

[Merrill Higginson]

Validation can't handle a message resource that does not use the default key. To get around this, put all your validation messages in a bundle that has no key attribute. This will cause it to use the default key.

[Timothy Sam]

Thanks Merrill! What would I ever do without you guys! Do you this is an issue with Struts? I don't think it should ever be left that way... Or maybe I'm just not reading the docs enough. Anyway... It solved the problem! Thanks!
