Null Pointer Exception on Opening Solution after Upgrading

kions · March 5, 2007, 3:23pm

Hello,

We have a solution that interfaces with SAP through an ODBC driver.

The solution worked fine (well, not fine, but it WAS working) using Servoy 3.0. We tried upgrading to Servoy 3.1 a while ago, but it caused problems with our navigation system. So we reverted to 3.0.

Just recently, we found a fix to the navigation issues, so we attempted to upgrade to Servoy 3.1.3. However, when we do so, we get a “Cannot load data - NullPointerException” error message when loading almost any form.

It therefore appears that because of the upgrade something with how Servoy was interacting with the ODBC SAP driver got broken.

Help…

Can you show us the stack trace in the log file?

Sorry for the long delay in replying…

Just to reiterate the problem:

We have a solution that works fine in 3.0.
However, attempting to access the same solution using 3.1.3 gives a nullpointerException.

That NullPointerException occurs after choosing the solution to load from the popup list.

The database configurations on the dbservers tab are correct - or at least match the configurations in the 3.0 Developer.

Any help in resolving this issue will be appreciated, since, as it stands, we have no upgrade path.

Thanks
Kion.

Here is the output from the Servoy log file:

Try using another jdbc driver that connects to SAP.
It may be related to the jdbc-odbc bridge.

Rob

kions · April 6, 2007, 10:36pm

Are there any other possible solutions that I could try? The SAP driver currently in use works fine with 3.0… was there some fundamental change that occurred in terms of connectivity when 3.1 was developed?

The reason I seem reluctant to replace the driver is because we inherited the driver from a previous application. I’m not sure how easy it would be to obtain a new driver.

Of course, if this is the only possible solution, i’ll have no choice but to source another driver, but if it’s possible that there might be another solution to the problem, I’d prefer to try that before trying to source a new driver.

Thanks,
Kion

rgansevles · April 7, 2007, 7:19pm

Kion,

The problem with the jdbc-odbc driver that it does not allow getting the same value from the resultset twice (i found that out just now) which is pretty strange behaviour for a jdbc driver.
We happened to do just that in the 3.1 release and it is no problem for any other jdbc driver we know.

Another possibility is moving the repository to another database, for instance sybase ianywhere which is bundled with servoy.
You can still use the SAP db for your application data.

Rob

kions · April 7, 2007, 9:07pm

Rob,

Actually our repository IS a sybase database, from the bundled iAnywhere DBMS. In addition, most of the application’s data is also stored in sybase. In fact, we don’t directly connect to the SAP database in Servoy… we instead have added the SAP tables we needed as proxy tables in the sybase application database.

Therefore, when i think about it, I may have given some mis-information - the only SAP jdbc driver we explicitly use is when interfacing with SAP via a custom plug-in that we created. In other words, there is no SAP jdbc driver in the /drivers directory of Servoy - only in the /plugins directory for use with the plugin.

kions · April 12, 2007, 1:02pm

Hey,

Are there any other suggestions to solve this problem? It’s somewhat of a show-stopper, since it doesn’t allow us to upgrade so we can’t take advantage of new bug fixes…

rgansevles · April 13, 2007, 4:58pm

Kion,

You could try copying your sap driver from the plugins directory to the drivers directory and modify the jdbc url accordingly in the db servers tab.

Rob

Kion,
