Re: Create button instead of html:link to JSP page

I thought that html:form transparently handles URL rewriting (or something
related to that).  Is that not the case?

logic:foward results in IllegalStateException

[Calvin Lau]

I currently have a welcome page that requires an action be
done to grab announcements from the db.  On my welcome page,
"index.jsp", I have:
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic" %>



Under struts-config.xml's global fowards, I have:


And under struts-config-xml's action-mappings I have:

  


When I hit my homepage, it loads fine but I find this in the
log file:
StandardWrapperValve[jsp]: Servlet.service() for servlet jsp

This only happens with the forwarding.  Anyone know how I
can fix this?

Re: To Strut or not to Strut that is the question?

The known public examples are listed at

A property designed Struts application will list *everything* in the
Struts-config, which I think is a great advantage over any other
approach. You can also see where the flow is going ~without~ consulting
the source for dozens of classes. Sometimes, it's just hard to put new
wine in old bottles ;-)

It's open source, and can be reviewed just like the rest of your code.
(And it is also better *documented* than most of the "production" code
I've seen.)

The primary Struts developer, Craig McClanahan, not only wrote most of
Tomcat 4, he is now the implementation engineer for Sun's new Web
Services package. I'd think most development directors would like to
have people like Craig on their "team". ;-)


> Who do we call if we find bugs?(rather than posting message on the boards)

There are a number of Struts consultants listed at 

http://husted.com/struts/resources.htm#consultants

It's also important to remember that since it's open source, you can
make any fixes you deem necessary without anyone's help ;-)


>they are saying that it is open source therefore it is impossible to 
incorporate it on a production release

The Apache License permits use of the software in a commercial release.
No worries there!

Tiles Problem

[Darryl Pentz]

Hi all,

I sent this email yesterday but it doesn't seem to have gotten through to 
the list, so I'm resending. Basically, I have a problem with Tiles execution 
of templates (components). I'm using the design where the main body of the 
page is inline to the  tag. In other words. I have:


   
   
   

   ... main body HTML here ...

   


This helps me eliminate the need for duplication of the pages. I thought it 
was working fine when I got the first page of my search page functionality 
to work. However when I re-run the search, the page simply redisplays the 
results of the first search, even though the Struts Action class correctly 
goes off and retrieves the results of the second search and places the 
result in the session.

I placed a simple <% System.out.println("Top of page reached."); %> above 
the insert tag and it is displayed on the console on the search retry, so it 
seems like somethings hanging trying to execute the template tags for the 
second time. One time, in frustration, I hit the 'Search' button numerous 
times, and when I Ctrl-C'ed the app server, a whole bunch of 'Connection 
reset by peer' stack traces appeared before the app server shut down, 
indicating that my requests were waiting somewhere. Where? I don't know.

So if someone has some idea where things might be going wrong, I'd 
appreciate any pointers. Cedric? Is there something in my code I should look 
for. It's not hanging at a point that it could be due to my code having a 
threadlock so I'm confused.

thanks in advance,
Darryl Pentz
