Major The method getTemplatePropertyDefinitions, in the class AdminFactory.java.
The datasource name should be "xa-data-source" instead of "data-source" when the datasource is XA. See the code snapshot below:
// get JDBC properties if (isXA(templateName)) { cliCall("read-resource-description", new String[] {"subsystem", "datasources", "data-source", stripXA(templateName)}, null, builder); addXAProperties(props); } else { cliCall("read-resource-description", new String[] {"subsystem", "datasources", "data-source", templateName}, null, builder); addDriverproperties(props); }
Another issue, when reading using the method getDataSource in the class AdminFactory.java, it is not getting the properties recursively. and the connection properties are returned as undefined like below:
"xa-datasource-properties" => { "DatabaseName" => undefined, "PortNumber" => undefined, "ServerName" => undefined }

[TEIID-5827] XA datasource properties are undefined

added a comment - mtawk with the existing logic it looks like that would need to be set via the connection-properties property as URL=jdbc:oracle:thin:@oraclehost:1521/ORCL - I think this needs some tweaking as the code has special handling only for a handful of xa properties: ServerName, PortNumber, and DatabaseName

We encountered an issue with xa-datasource using Oracle. We are not able to set the xa-datasource-property "URL" for the oracle connection.
<xa-datasource-property name="URL">
jdbc:oracle:thin:@oraclehost:1521/ORCL
</xa-datasource-property>

added a comment - Updated the name and the logic in getDataSource to look at the xa-datasource-properties as well.

URL has now replaced connection-url for xa as full property. Most other xa-datasource-properties will need to be set through connection-properties though.
