Subject Struts in WebSphere - VICTORY !!!!!!! - Addendum

If changing the DTD's to SYSTEM, do so ONLY AFTER using the Convert a War
util.  Ant doesn't seem to like it the other way! :)

Subject: RE: The Continuing Misadventures of Struts in WebSphere -
VICTORY !!!!!!!


After quite a bit of effort, I have finally gotten the Struts example to
work flawlessly in WebSphere 3.5.3.  What's funny is that I was reading your
post Richard and was thinking to myself: "Gee, I've done ALL of this EXACTLY
-- in fact I'm even on the same OS, just different drive letters, WHAT could
be wrong??" Then it hit me, looking through your steps below I found the one
thing that was different that had completely slipped through - jaxp 1.0.1.
I was using jaxp 1.1.1!!  Crimson is a separate jar now, that includes the
stuff from parser.jar, but it apparently does something different then 1.0.1
and it was just screwing everything up!  I downloaded 1.0.1 and got
significantly further then I ever have, but ran into another problem.
WebSphere reported that the public identifiers for the DTD's were malformed
URLs.  Luckily, I saw on another mailing list an issue with WebSphere &
Struts not liking PUBLIC DTD refs, so I changed them to SYSTEM and away it
flew - flawlessly. 

For those people who run into these issues (and because I have to document
it for work anyway - here is Richard's list again revised with more detail
on some of the bugs I encountered. (BTW, adding web to the classpath did not
help me, I had to move it to the servlets directory). 

Server: Windows 2000 Server with WebSphere 3.5.3 Advanced

1. Start up the adminserver. 
2. Start up Admin Console.
3. Use the Convert War file task to convert the struts-example.war from the
struts-b1 distrib as-is.
4. Convert to the default_server, default servlet engine and standard
install directory (c:\websphere\appserver\hosts\default_host).
5. Create a WEB-INF directory in the servlets dir and copy
struts-config.xml, database.xml AND web.xml into it (Keep WEB-INF with all
the TLD's under web - both WEB-INF directories must be present).  
6. Copy jaxp 1.0.1's (NOT 1.1.1's) jaxp.jar and parser.jar to the servlets
directory of the strut-example webapp.
7. In the servlets directory, open struts.jar with WinZip.  Extract the
three DTD's (struts-config_1_0.dtd, web-app_2_2.dtd and web-app_2_3.dtd)
into the servlets directory making sure you use folder names (so the files
extract to servlets/org/apache/struts/resources). 
8. Click on struts-example in the Admin Console under Default Server/Default
Servlet Engine and click the advanced tab on the right hand side of the
screen. 
9. Down where it says Default Error Page, enter /ErrorReporter and then
click Apply.
10. Start the Default Server via the Admin Console. You should see a whole
bunch of ActionServlet messages in the default_host_stdout.log file with no
exceptions.
11. Via a browser accessed the app using
http://localhost/struts-example/index.jsp.
12. If it returns "Application not Available" then go back to the Admin
Console, right-click on struts-example and select Restart WebApp. 
13. Once it reports success, go back to the URL above and try again - it
should work flawlessly.  

For whatever reason, some installations do not like XML files that reference
PUBLIC DTD's - if in looking at the default_host_stdout.log file you see
errors about invalid public URL references during DTD registrations, or if
your pages say "cannot find //logon or //saveRegistration (ie. action
mappings) then do the following:

1. Stop Default Server
2. Go to servlets\WEB-INF\ and edit web.xml and struts_config.xml.
3. In the DOCTYPE declaration, change the word PUBLIC to SYSTEM and
completely remove the line that reads "-//Sun Microsystems, Inc.//DTD Web
Application 2.2//EN" from web.xml and remove "-//Apache Software
Foundation//DTD Struts Configuration 1.0//EN" from struts-config.xml. 
4. Save these changes and go back to step 10 above. 

Just as a troubleshooting guide - 

If you are getting errors like "Cannot find ActionMappings, etc..." or
"Cannot find key org.apache.struts.MESSAGE"  then your application is most
likely still bombing on the struts-config issue that Richard discovered.
The above steps SHOULD correct that leaving nothing out.  If you are getting
404 errors about //logon or something not found, then you are still having
XML config troubles and it is not initializing the Action servlet properly.
Follow the steps above in regards to DTD's and it should work.

As a final thought, I obviously haven't gotten to test too much but I don't
believe that there are ANY coding changes that need to be made to the actual
struts source.  Everything about getting it to work in WebSphere has been a
WebSphere configuration issue thus far (and I don't think I'll be having any
more). 

Thanks for your help Richard and I hope others benefit from this as well! :)
