Exception in inserting record for entity service

[Former Member]

Hello Everybody,

I have created simple entity service: Employee.

I have included 3 fields in it.

Created one finder method "GetAllEmployee".

I have rebuilt and deployed project on the server.

When i tried to insert new record for this entity service from service browser:

http://<server>:<port>/webdynpro/dispatcher/sap.com/caf_UIservicebrowser/ServiceBrowser?cafsource=true

I got following exception:

ERROR. Exception in method create.

What should be the reason behind this?

Hi Bhavik,

I have the same problem with CAF (problem with DATASOURCE_LOCAL_DA variable).

Do you have found a solution?

Thanks,

Mikhail.

Hi Bhavik,

The problem source is in incorrect CAF version.

Just check it:

1. Login to http://<host>:<port>/sap/monitoring/SystemInfo as administrator.

2. Check the sap.com/SAP-JEECOR and sap.com/SAP-JEE version.

3. Click "all components..." link and check the CAF version in the top table.

4. Go to development studio, then Help -> About Sap NetWeaver Developer Studio. Check the version value.

Type this info here.

Best reagrds,

Hi Aliaksei,

I checked my Server version and CAF version.

Both are: 7.0.0 SP4

My NWDS version is: 7.0.0

Thanks,

Hi Bhavik,

Try to review defualtTrace.1.trc or defualtTrace.2.trc, I mean the latest modified defaultTrace.trc.

Also check latest from

cluster\server0\log\applications\com.sap.caf.rt\CAF.<num>.trc

and

\j2ee\cluster\server0\log\applications\com.sap.caf.ui

logs

It actually impossible to make some assumption without original exception.

Hi Aliaksei,

I have changed the severity level of the trace. Then I got this exception.

Error in CAF:RT:oal:handleException(Throwable)

Hi Bhavik,

Actually, too many reasons are possible.

Check the

\usr\sap\<SID>\<INSTANCE>\j2ee\cluster\server0\log\defaultTrace.0.trc

for according exception.

Also specify a CAF version.

Best regards,

Aliaksei.

Hi Aliaksei,

I didn't get anything in the defualtTrace.0.trc.

Is anytrhing need to do to get this exception in log?

This is my first application in CAF.
