Bean Usage - Collections

["Kamholz, Keith (corp-staff) USX" <kk...@moog.com>]

Hi everyone,
I'm new to struts and right now I'm working on some collections in my app.
I have an EntryHolder bean class that has 3 properties (ArrayLists of
entries) which each hold a different type of entry.  Each type of entry is
it's own class.  I then have a form that fills in the info into the entry
class.
I believe I can just use the <bean:define id="entries" name="beanName"
type="com.moog.us.beans.EntryHolder"/> tag (before the link to my form page)
to instantiate the EntryHolder bean, right?
In order to the put the entry into the corresponding ArrayList, do I add it
to the list in my Action that handles the form?
If so, how do I access that bean in the action?  My only guess is that I get
it from the "request" parameter.
Any input would be greatly appreciated.  Thanks!

Struts and WebLogic sp10

[Mark Chester <mc...@vml.com>]

All,

Still trying to install struts on WLSsp10. I have implemented the workaround
that uses WebAppStartup. Things seem to be installing correctly but then I
never get the log message

       // Invoke stub with null request/response to get init() called
       try {
           stub.invokeServlet(null, null);
           this.services.log().info( "Successfully loaded servlet: '"
               + stub.getName() + " (in context: "
               + webAppContext + ")" );
       }

Here is this snippet from the startup log starting with the end of the .

I'm suspicious of pageCheckSeconds = 1. I've set this in the initargs to -1
per http://jakarta.apache.org/struts/userGuide/installation-wls5.html
but somehow this is being "over-ruled". Any help would be *greatly*
appreciated.

Thanks,
Mark Chester
