Hi Maduranga, Yeah, seems like the packages exported from the stub is not correct. We will have to fix those eventually, @Chanika please note.
But for your requirement, I'm guessing you will have your own admin service operations when adding user stores and all. So calling another service from through a backend service is overkill, you can directly call the required functionality directly. Check here [1] to see how "testDataSourceConnection()" is implemented, you just have to use a logic similar to do it. But then again, if your requirement is directly from the UI to check the validity of database connection information, then yeah, do fix the data source UI component as you've done, but you have to check all the usages of those packages and fix those as well. [1] https://svn.wso2.org/repos/wso2/carbon/kernel/branches/4.2.0/core/org.wso2.carbon.ndatasource.core/4.2.0/src/main/java/org/wso2/carbon/ndatasource/core/services/NDataSourceAdminService.java Cheers, Anjana.
