    Unable to load DataSource for ID-Please help!

    Hi Guys,
    I am using SMARTGwtEE(Eval) 2.5, with GWT2.0.4 in Eclipse STS2.7.1
    I tried to convert an existing application developed with SmartGwt2.5 to SmartGWTEE2.5. I followed the steps exactly as mentioned in http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/docs/SgwtEESetup.html
    But I am getting the following errors:
    1.javax.servlet.jsp.JspException: Unable to load DataSource for ID: table3
    and after that
    2.[ERROR] Invalid version number "2.1" passed to external.gwtOnLoad(), expected "2.0"; your hosted mode bootstrap file may be out of date; if you are using -noserver try recompiling and redeploying your app
    Following is the logs

    See FAQ on reasons for DataSource loading to fail - although actually it's obvious - file name does not match ID.

      Ah OK! I changed it and it is able to load the DS. I will keep this in mind.
      The second problem also got resolved by clearing the browser cache, delete everything under war/<appname> and recompiling the code.

      However the application is rendering in Firefox(3.0.3) but it is not appearing at all in IE(ver 8). It was appearing before when I was using SmartGwt2.5 only.
      There is even no errors in the logs also. The GWT logs says module has been loaded.
      Any clue, where I am messing up?

        Clear cache on that browser too, if that doesn't work, post more information (see FAQ).

          Hi,
          I added the following in the html and then it works fine.
          <meta http-equiv="X-UA-Compatible" content="IE=7">
          This is been mentioned in the FAQ also.
          Thanks again,
