Com.sap.xmii.Illuminator.logging.LHException: java.lang.NoClassDefFoundErro

Question

Hello,
Intermittently users get the following error when logging into the application which is built upon xmii:
com.microsoft.sqlserver.jdbc.SQLServerResource
At this point in the application it is trying to read information which is stored in a SQLServer database.
We see the following errors in trace files:
application [XMII] Processing HTTP request to servlet [Illuminator] finished with error.
The error is: com.sap.xmii.Illuminator.logging.LHException: com.sap.xmii.Illuminator.logging.LHException: java.lang.NoClassDefFoundError: com.microsoft.sqlserver.jdbc.SQLServerResource
Exception id: [00145E4D6... [see details]
This is running on a NW JavaAs 7.0 SP18, MII 12.0 SP8.
We've replaced the JDBC driver with one which SAP support told us would work, but that did not fix the problem either.
We can get the problem to go away for a period of time by simply disabling and then re-enabling the Data Server connection.  It is using the IDBC Connector with a SQL connector type.  STATUS shows No. Connections Used 0, No. Connections Available 1, Max No. Connections Used 2.  Max. Wait Time 0.0.
Ideas?

Hi John,
Before connecting SQL server with SAP MII, try connecting SQL server independently.
It helps to narrow down the problem.
If the independent connection works fine, try connecting with SAP MII with proper JDBC drivers
Go through the SAP Note 1109274 & forum MII 12.1 - connection to MS SQL2005 database
for more information on JDBC drivers.
Thanks
