Hi Faathima,
>From what i can comprehend from the error message and what your trying do,
is that you are trying to update a database table with a new attribute, the
reason the error is popping up is because the database table to which you
are trying to add the attribute does not exist or not accessed properly
through the code, therefore the server is trying to create a new db by
calling the addDatabase function. Please check if your reference to the db
is correct in places where ever you are using the db reference.
*ERROR {org.wso2.carbon.rssmanager.ui.RSSManagerClient} - Failed to create
database 'db10' : Exception occurred while trying to invoke service method
addDatabaseorg.apache.axis2.AxisFault: Exception occurred while trying to
invoke service method addDatabase*
Thank you,
