struts

[Vardhan Muthineni]

HI ,
In <html:link> struts tag iam using the action attribute.what i have to give in action value
Ex:
I have <html:link action="/category">Category page</html:link>
in strits config.xml how i have to give this action
<action path="/category"
type="CategoryAction"
name="categoryForm"
scope="request"

<forward name="success" path="/category.jsp"/>

Is this the correct way of using action attribute in html:link tag
can any one suggest me..
tellme the url that i can get html:link action examples

The code you have written should work. Are you saying that it doesn't?

I'm having a problem with an augmented version of this example. I am trying to return a string which I build from an ArrayList in my Action. I can return simple text but I cannot get my string built from the ArrayList generated more than once. I get the response the first time but not the second and my code only executes to the point where I do:

    
 
System.out.print("I just got the rows");
 

I'm not getting any kind of errors in the stack or tomcat logs.

The only thing I see is this message in the Eclipse console when tomcat is shutting down:

INFO: Waiting for 4 instance(s) to be deallocated

It's not always four instances, usually depends on the number of times -1 that I have run the action
