point.

Shivani,
You may want to take a look at the suggest tag provided by
Struts-layout taglibrary.

I have personally used this tag and it is quite easy to get it
working. The best thing is that you do not need to write a single line
of Javascrip

Hi,
Before I introduced Sitemesh into my ecosystem, I used to handle
exceptions in a "declarative" fashion in the struts-config.xml.
For example, an entry in struts-config.xml like:
would handle a good subset of my Database exceptions.
Now comes sitemesh, which is really a "servlet-filter".

Hi,
I am trying to generate a *dynamic* menu.
I have a regular 'java' function which spits out menu tags (struts
layout taglib related).
The intention is to use Sitemesh to create the menu depending on the
access permissions of the logged in user without any "dirty coding" in
JSP's.

Do I need to do something else to ensure validation.xml is called and
so is the code in validationform's validate function?

Assuming you want to do "form-based" validation, can you check if your

If it extends a simple "ActionForm", validation will not work.

The trick is to point the "input" variable in your struts-config.xml to the
action class that "generated" the JSP page rather than the JSP page itself.
On failure of validation, you should redirect it to the "preparation" action
class for the form that solicits information for you - the action
this makes sense.
What do you think?

Or perhaps, as mentioned earlier in this thread, having an applet to which
the server could "push" information should do the trick.
I would disagree on your conclusion that pull is *the* way to achieve your
'push alert' on http.
Some points on which you will base your decision maybe as follows:
The error means that your action form does not have a getter method for the
described property.
If you make sure you have the required property in the actionform and try
it, it should work fine. Post the code of action form and
struts-config.xmlif you still cant solve it.

Have a strDate which is of type string. The setStrDate() needs to be coded
in such a way that it sets the date attribute also which is of type Date.
The getDate() which returns Date object can be used in the "business"
layers. For example, my Hibernate mappings map to getDate and not to

There are two approaches I can think of right now. You will need to "burn"
this querystring information into (a) the form object or (b) the session.

These are two different caching scenarios we are talking about.
Tomcat connection pooling caches "Connection" objects.. not your domain
objects. However, Hibernate caches business objects (POJOs). You could use
Tomcat's connection pool along with Hibernate's pooling of business objects.

simplistic.
