Problem in querying synonym using cachedRowSet & cachedDataProvider

Question

Hi....
I have some trouble using cachedRowSet and cachedDataProvider combination. The problem was occured when I refreshed chachedDataProvider, my table component in pages show "No items found.", whereas... i'm sure there is nothing wrong with my query.
here the detail
i have cachedRowSet in my SessionBeans1 named globalRowSet
globalRowSet.setDataSourceName("java:comp/env/jdbc/MIMSOE_Oracle");
globalRowSet.setCommand("SELECT EQUIP_NO, ORIGINATOR_ID FROM ELLIPSE.MSF620 WHERE EQUIP_NO LIKE ?");
globalRowSet.setFetchSize(100);
globalRowSet.setMaxRows(100);
globalRowSet.setPageSize(100);and then i have data provider in my pages (TestPage.jsp), linked to globalRowSet, named cachedRowSetDataProvider1
cachedRowSetDataProvider1.setCachedRowSet((javax.sql.rowset.CachedRowSet) getValue("#{SessionBean1.globalRowSet}"));Note that in globalRowSet SQL command, there is a parameter (marked by '?'), so i put this code in init() method.
getSessionBean1().getGlobalRowSet().setObject(1, "%MUA21%");that code replace '?' in my query with '%MUA21%'. so in the first time i open the page, my table in TestPage.jsp dont display empty data. this code was worked.
then i put a button and a textfield in TestPage.jsp. I put them for dynamically changes my query parameter.
public String button1_action() {
try {
getSessionBean1().getGlobalRowSet().setObject(1, this.textField1.getText().toString());
this.cachedRowSetDataProvider1.refresh();
} catch (SQLException ex) {
Logger.getLogger(TestPage.class.getName()).log(Level.SEVERE, null, ex);
return null;
}I ran my webpages, i hit the button, and i saw anomalies.
before i hit the button, my table shows a lot of records. but after i hit, my table shows nothing but "No items found." displayed in table body.
I debugged my code, and found nothing wrong with my query. I executed my query in separated sql editor and it works flawlessly,
I truncated my code line by line for debugging, and found this line of code was the main reason for that problem
this.cachedRowSetDataProvider1.refresh();I'm not sure why this line of code didnt work in my project. maybe this is because of my globalRowSet querying data from ORACLE synonym. please note that 'MSF620' in my query (SELECT EQUIP_NO, ORIGINATOR_ID FROM ELLIPSE.MSF620) is not a table, but synonym. I made same version but use oracle table (not synonym) and work fine...
can anyone help give me a solution for this issue? ...
please help..
i have no progression for last 2 weeks because of this issue.......

Hi Tushar,
In your SELECT you select only record for record and you put the result into the header line of the table.
Try:
SELECT posnr
      FROM RESB
      INTO TABLE IRESB
     WHERE VORNR = '0010'
       AND AUFNR = '720000100'.
Then you can loop over your internal table!.
Regards,
John.
