Advisories for OGSA-DAI R3

The following advisories have been issued:

Previously working Client Toolkit applications fail with a perform document validation error

The following error message will be logged: 

Unexpected DAIException: uk.org.ogsadai.client.toolkit.RequestException
The perform document does not validate against the expected XML schema."

If you have the source version of the release, you can correct this bug by changing the following method in the UniqueName.java file and rebuilding ogsadai.jar:

  • old version: 
    /**
  * Returns a unique name based on a Hex timestamp seed
  * @return String
  */
public synchronized String getName()
{
    mCurrentName++;
    return Long.toHexString(mCurrentName);
}
  • new version: 
    /**
  * Returns a unique name based on a Hex timestamp seed, of the form
  * ogsadai-100033ad2a7.
  *
  * @return String
  */
public synchronized String getName()
{
    mCurrentName++;
    return \"ogsadai-\"+Long.toHexString(mCurrentName);
}

This bug is corrected in Release 5.
