Help - running the Persistence Example

Question

Hi All,
I am running on NW2004s SPS10
Please somebody has a Persistence example?? I can't run the SAP examples on my PDA (Dell AXIM X51v +Windows Mobile 2005) i found this information in the SAP Note 717510
<i>MDK: Links to MI client home page <b>are not working</b> in some example programs
Application is working fine but for the ME Home link for 3 MDK applications: MDK_persistence_query_sortJSP, MDK_persistence_queryJSP and MDK_persistence_simpleJSP.
( Changed at 30.04.2007 )</i>
I would like to run the MDK_persistence_simpleJSP
There is another Persistence example? Can somebody give me a link to download it. I want to learn how to use the persistence api, but without any running example is very difficult to test the code.
Best Regards,
Erick Ilarraza

Hi all! Thank a lot for your replies.
I run the MDK_PERSISTENCE_QUERYJSP in the Windows XP SAP Mobile Client, it runs Perfect!
But when i try to run it on my PDA it give me this error:
Error: 500
Location: /MDK_PERSISTENCE_QUERYJSP/jsp/menu.jsp Internal Servlet Error:

But this has no sense!! since both Windows XP MI Client and PDA MI CLient are at the same version. So It run in my Desktop but not in my PDA.
I saw the menu.jsp file
They used the PersistenceExample class in two places:
At the beginning of the JSP: <b><%@ page import="persistenceexample2.PersistenceExample" %></b>
And here:
String value = dataBean.getTableContent(i, j);
            if (i > 1) {
                 <b>value = PersistenceExample.encodeForHtml(value);</b>
            if (value.trim().length() < 1){
                 value = " ";
From a point of view of Java, everything appear to be "OK"
The other error is about a "version" should i configured the application to Version 45 in the nwa when i deploy the application?
