Query Template Not Loading

Hi,

We are using XMII 12.0 and NW 7.1,

We have deployed Query templates in web pages and while loading , applets are not loading...

in NWA we saw the following error

Unable to load template PATH [pathId=<id no>,<Query Template Path>]..

Category: /Applications/XMII

Location: com.sap.xmii.Illuminator.templates.TemplateManager

Application: sap.com/xapps_xmiiear

but the template mentioned in the error is in the same path and working fine if we open from work bench.

and also we are seeing the following error.

Exception of type com.sap.sql.log.OpenSQLException caught: Synchronisation reader could not access data source java:comp/env/jdbc/XMIIDataSource..

Pages are not working...

What is the problem? How to solve it?

Regards,

Senthil
