Embedding Crystal Reports with parameters in web page

Question

Hi,
I have created a sample report file and configured it with a parameter field. On embedding this report file in the web page, as expected I am prompted to enter value for the parameter. After entering value and clicking OK, CrystalReportViewerServlet delegates the call to the custom JDBC connector implementation which is the data provider. However, the web page doesnu2019t show the retrieved resultset but shows a page with some text like this:
{"update":{"children":[{"children":[
{"args":{"curPage":1,"numPages":"1"},"cons":"bobj.crv.newSelectPageControl"},{"args":{"searchText":""},"cons":"bobj.crv.newSearchTextControl"}
],"cons":"bobj.crv.newToolbar"},{"args":{"displayDrilldownTab":true,"initTabIdx":0},"children":[{"args":{"isMainReport":true,"label":"Main Report","viewStateId":"1"},"children":[{"args":{"content":"\r\n 
On debugging I could see, that the parameter value from the prompt is correctly passed from the CrystalReportViewerServlet to the custom Connector (i.e., the sql query is updated with the parameter value) and the connector fetches the data also.
I also tried embedding another .rpt file with few parameter fields configured (where user input values are just passed to the details section of the report for display). However on running this web page also I get the same error.
Report files with no parameter fields configured are working fine when embedded in web page.
Any thoughts would be appreciated.
Regards,
Ria

I would take a look at running our simple [sample application |http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/307224d2-3d11-2c10-fe86-d87bab901bee&overridelayout=true]that views reports to see if you have the issue there.
