Hi
I have got a lot from this website. So i thought it would be a good idea to share what i learned in WSAD & struts here..
1)Cause of Major Minor Version Error
check the window-> preference->java->compiler->JDK Compliance level
by default it's 1.3
also check the JRE
2)when creating the web project override default setting in the wizard
to struts version 1.1(beta 2)
http://www7b.software.ibm.com/wsdd/techjournal/0302_fung/fung.html Error caused by this i think it is Error 500 Cannot find message resources under key org.apache.struts.action.MESSAGE
I don't think this is true always but a possible chance
Other chances are absence of
<init-param>
<param-name>application</param-name>
<param-value>ApplicationResources</param-value>
</init-param>
in the web.xml
<load-on-startup>1</load-on-startup>
with a value other than 1 i think can sometimes cause problems
with servlets
3)http://www.reumann.net/do/struts/lesson1
if u r using el extensions in WSAD . I warn u with some possible errors
caused due to versions of struts, due to using el extension tlds.
4) For a Beginner my suggestion is create a war file and test it on Tomcat
Another suggestion is try
http://jywiki.sourceforge.net/index.php?JythonServlet to test u r logics Jython is real handy stuff
5)Error 500: Server caught unhandled exception from servlet [JSP 1.2 Processor]: null
this has something to do with programatical error see the log file and look for which class is this generating
Once again i am beginner and things above stated can be completely wrong or misguide you so be carefull
