RE: Transmission of a session using jsessionID
FWIW: I had a similar situation and used cookies to pass encrypted values
between the web apps. I also used a filter to check for changes in those
cookie values and to put the values from the cookie into the correct web app
session.

in a row with a primary key which == id of the session of the authentication

Just my 2 cents,
which ever application creates the session, you could create a unique
indentifier,
store it in a dsn, then write indentifier to url for all inetractions with
applications and verify with
dsn lookup. This may not be the most intuitive approach, maybe, depends if
both
apps have access to dsn. You also would want to do a dsn cleanup for expired
indentifier's.
Or have application dependant sessions verfied by value of url
or hidden form field so its not actually seen, and cut out the dsn
altogether.

RE: JSTL, Tiles PutList and Tomcat 5.028
Thanks James,
It looks like if I put a break point in the setItems() method of the forEach
I am passed a string - that string appears to be the .toString() of the
SimpleMenuItem(s) collection.
I check the .toString() of SimpleMenuItem and it has the format of the long
string below from my previous message - i.e. the 5 or so items in the
collection.
How does / or should the ForEach turn that string back into a collection of
items.
When looking at the parameter on the method signature I had expected that I
would get the "EXPRESSION" that needed to be evaluated by jstl within the
tag instead it appears the expression has been run prior to the call of the
method an then the .toString() has been called.
Thanks for everyone's help and input on this - I have now spent two/three
very late nights tracking this down.

RE: JSTL, Tiles PutList and Tomcat 5.028
One other thing to add :> there is a "key" in the pageContext attributes
called topnav and that DOES contain an actual collection of SimpleMenuItems.
The plot thickens - how does the ForEach get the collection?

Hi Matk,
I have the following statement
Which I "think" am lead to believe it imports all the attributes into the
page scope.
In an effort to figure out what was happening I downloaded the jstl 1.0.6
and built a debug project in eclipse so I could step into the ForEach tag
and I am not sure what I am really looking at yet in there but it appears
that indeed the item does contain a string and that the items collection on
the tag has a "somewhat" string delimited representation of the collection.
See below: This is that actual value in the string in the debugger... Is
this how it is stored then is ir "reconstituted" into SimpleMenuItem(s) as
the tag loops. The string "looks" like a collection because of the "," i.e.
it looks like a string tokenizer.
[SimpleMenuItem[value=nav.adminhome,

And give this sting in the items - the actual when call to next() within the

On a side note - not sure if this means anything - when I compiled the
course I was required by eclipse to add two new methods to the
PageContextImpl in the org.apache.taglibs.standard.lang.jstl.test package
does it looks like perhaps the different JSP version might be an issue. i.e.
will jstl 1.0.6 work in Tomcat 5.0.28?

RE: JSTL, Tiles PutList and Tomcat 5.028
One other thing to add :> there is a "key" in the pageContext attributes
called topnav and that DOES contain an actual collection of SimpleMenuItems.
The plot thickens - how does the ForEach get the collection?

Hi Matk,
I have the following statement
Which I "think" am lead to believe it imports all the attributes into the
page scope.
In an effort to figure out what was happening I downloaded the jstl 1.0.6
and built a debug project in eclipse so I could step into the ForEach tag
and I am not sure what I am really looking at yet in there but it appears
that indeed the item does contain a string and that the items collection on
the tag has a "somewhat" string delimited representation of the collection.
See below: This is that actual value in the string in the debugger... Is
this how it is stored then is ir "reconstituted" into SimpleMenuItem(s) as
the tag loops. The string "looks" like a collection because of the "," i.e.
it looks like a string tokenizer.
[SimpleMenuItem[value=nav.adminhome,
link=/aems/session/changefiltertoken.do?btnResetFilter=true,

JSTL, Tiles PutList and Tomcat 5.028
Hi All,
I have a jsp page that I am trying to run on Tomcat that currently works in
Weblogic. It appears the primary problem is that the forEach tag is not
putting the variable menuItem into the pageContext attributes and or it
thinks the menuItem is of type String. I am not sure where my actually
problem is (tiles, tomcat etc).
It appears Tomcat is generating code when compiling the JSP that isn't aware
of the type of class the org.apache.struts.tiles.beans.SimpleMenuItem is -
it looks like at run time it thinks it is a String.
A snippet of my JSP looks like this (jstl tags - partial):
my tiles def looks like this (partial):
and the generated servlet code looks like this - Is Jasper not compiling
this correctly???
_jspx_th_core_when_0.setTest((java.lang.String)
org.apache.jasper.runtime.PageContextImpl.proprietaryEvaluate("${menuItem.to
oltip=='help'}", java.lang.String.class, (PageContext)_jspx_page_context,
null, false));
And when the page runs I get this serlet exception:
ServletException in:/menu.do?menu=topnav] Unable to find a value for
"tooltip" in object of class "java.lang.String" using operator "."'
When I check the pageContext attributes via a debugger I actually see an
item in the collection with the key "topnav" and it contains a Vector of
items that appear to be of type SimpleMenuItem. However I never see the item
called menuItem that I thought the forEach tag would place in there for me.
Thanks for any help you may be able to provide,
Jerry Rodgers
