My LogonView.jsp Displays A Blank Page
My LogonView.jsp displays a blank page. I have no idea
why nothing is written while the
MessageResources.properties file is found.
I would have gotton HTTP Status 500 if the
MessageResources.properties is not found or the value
of the corresponding key in the bean:message tag
cannot be picked up. I did not get any error message.
I cannot figure out the reason. Please help.

You need both the Struts-EL and Struts jars. If you look in the "struts-el"
distribution, you'll see a "strutsel-exercise-taglib" application. You can
inspect that application to see the jars that you'll need. If you're getting
errors from the validation javascripts, I'm not sure what is happening there.

Help on installing struts-el
Posted by Richard Mixon <rn...@custco.biz>.
Where can I find instructions on how to use the struts-el version of struts
instead of the standard struts "lib" files? The README does not cover this
and that seems to be all there is in the way of doc.
I'm laboring under the assumption that struts-el is a super-set of struts. I
should be able to move my existing application over and have it use the
"struts-el" jar files. I can then selectively change from, for example an
"<html:text" tag to an "<html-el:text" tag assuming I've setup the TLD's
correctly for my taglibs.
I had a document that explained it well - but tossed it the other day,
thinking I was not going to need it for a while. Guess what, I need it now
<:-). I remember that it said you needed to first use the standard struts
"lib" files and then selectively replace them with the files in the
"contrib" lib directory. I've been Googling for hours and searching the
archive - cannot find anything substantiative.
I tried just using the contrib/struts-el/lib directory files, but end up
getting errors from the validation javascripts issued by my
"<html:javascript" tags (cannot find the "required" validation).
Any pointers or advice are appreciated.
Thanks - Richard

Did you check your server log file?

Re: My LogonView.jsp Displays A Blank Page
Posted by Jason Lea <ja...@kumachan.net.nz>.
I can't see anything wrong, I'll ask some questions :)
How are you accessing the logonView.jsp? Requesting it directly or
through an Struts Action?
Where is the MessageResources.properties file? I see you use
<param-value>resources.version1.MessageResources</param-value> which
means it should be somewhere like
/WEB-INF/classes/resources/version1/MessageResources.properties
If you went through an action, does the action actually forward to
logonView.jsp? What is in your struts-config.xml?
Perhaps your log files will show what Struts did with the request?
