Error in Smart sync contacts app in SP14

[Former Member]

Hi,

I have recently upgraded the WAS from SP9 to SP14.

I am working on a contact application as a sample scenario to get accustomed.

I have created a webapp and after deploying it to mi client, it is giving an exception as follows

java.lang.NullPointerException

1. Should the name of the war file and the name of the mobile component in the web console be the same. In the above case, the war file is ContactSP14 and mobile component name is CONTACTSP14.

Hi Raja,

The null pointer exception u have given here is from the

standard method in the Controller class file.

method -showSyncBoNames();

in this method actually what they are doing is collecting the entire data from your syncbos which are in your SmartSync Application.

check these methods , then u will get the clear picture of the exception.

getTableWithSyncBoNames in TCP

getSyncBoInstances in SmartSyncDBAccess

From this code piece( getSyncBoInstances ) , this exception came. This means ur application has came down to ur client deveice , but there is some problems happened to the metadata and data to ur syncbos.

Check ur MCD in the middleware and check the metaRepMeta.xml file .Verify both are same or not.

Hi,

Is the error mentioned related to name of the application or any other error.

Since the deployment has not been successful, the NullPointerException is thrown, so try matching the names of the .war files and try again. It should go through.

Hi Raj - Yes, the names should be identical for successful deployment of the component to the device.
