Hi, All I am trying to use the taglib custom action to replace the java code in my JSP files. For example, originally I have: <% Vector myVec; ... for(int i=0; i<myVec.size(); i++) { myObj = myVec.elementAt(i); %> <%= myObj.toString() %> <% } %> in my JSP file, now I can easily replace it by: <ora:loop name="myVec" id="myObj" class="java.lang.String"> the obj is <%= myObj %> </ora:loop> The JSP using taglib will be easier to write and maintain than using embedded java code. But, here I have a side effect: When use embedded java code, I have more control on the positions to loop through, e.g. I want to loop from the third element at the left until the third element at the right side of the vector, I can easily change the java code to: ... for(int i=3; i< myVec.size()-2; i++) ... But how to achieve this using the taglib custom action?
I haven't actually tried this, but it is a final (not beta) release, so it should work: the iterate tag from the Jakarta-Struts Project, http://jakarta.apache.org/struts/struts-logic.html#iterate . You can set the offset attribute to your starting vector index and the length attribute to the number of vector entries you want to process.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to
run our stuff on 16 servers instead of 3.
