Hi
I am a new bee to ZK and we are trying migrating our SpringFramework/JSP/AJAX app to ZK. We are planning to move use ZK JSP tags so that we can quickly migrate our existing jsps to make it richer.
I am trying the example given in the ZK JSP Small talks in my application but in a new page so that none of our business logic is executed I get the following error
2007-10-26 15:06:20,587 [http-8080-Processor25] (StandardWrapperValve.java:257)-
ERROR: Servlet.service() for servlet jsp threw exception

I am using the following example

<z:tree id="tree" width="70%" rows="30">
<z:treecols sizable="true">
<z:treecol label="Name" />
</z:treecols>
<z:treechildren>
<c:forEach var="i" begin="1" end="3" step="1" varStatus="status">
<z:treeitem>
<z:treerow>
<z:treecell label="Item ${i}" />
</z:treerow>
<z:treechildren>
<c:forEach var="j" begin="1" end="3" step="1"
varStatus="status">
<z:treeitem>
<z:treerow>
<z:treecell label="Item ${i}.${j}" />
</z:treerow>
<z:treechildren>
<c:forEach var="k" begin="1" end="5" step="1"
varStatus="status">
<z:treeitem>
<z:treerow>
<z:treecell label="Item ${i}.${j}.${k}" />
</z:treerow>
</z:treeitem>
</c:forEach>
</z:treechildren>
</z:treeitem>
</c:forEach>
</z:treechildren>
</z:treeitem>
</c:forEach>
</z:treechildren>
</z:tree>
</z:window>
</z:page>
Please help us if this is a configuration issue. This will help us quickly evaluate if ZK is suitable for migration
Thanks

The error log shows you assigned a invalid Id to a ZK Component.
you can try to rename it to find out if it works.
I have tested the page you provide and find no error.
Can you provide your original JSP page?

Did you set component id which starts with "z_" ? It is not allowed since ZK reserve that for internal use.

We are simply using the above JSP within our Spring Web MVC Framework with Tiles.
If the above simple JSPworks, I would like to post process all my jsps using the ZK filter.
Help is greatly appreciated
