Using XQSL w/Datasource : ClassCastException

Question

I'm attempting to use XSQL in a Websphere 5.1 test server (WSAD) and I am getting this error:
Oracle XML Developers Kit 10.1.0.2.0 - Production
XML-25017: Unexpected Error Occurred
java.lang.ClassCastException: com.ibm.ejs.cm.proxy.OracleCallableStatementProxy
at oracle.xml.xsql.actions.XSQLRefCursorFunctionHandler.handleAction(XSQLRefCursorFunctionHandler.java:102)
The datasource in question is setup correctly since it works as implemented in the web app. XSQL appears setup correctly because it works with using XSQLConnectionManagerFactoryImpl and <connectiondefs>, and it also works using a AS400JDBCDriver Datasource with XSQLOracleDatasourceConnectionManager.
I'm using classes12.jar (and have tried it with the latest 3 versions). I'm using jdbc:oracle:thin with oracle.jdbc.pool.OracleConnectionPoolDataSource.
Finally, (not sure if this helps) when I decompile XSQLRefCursorFunctionHandler, line 102 appears to bomb here (see below), so I added a "date-format" attribute and value just for funzzies, without change in result:
if(s1 != null && !s1.equals(""))
oraclexmlquery.setDateFormat(s1);
boolean flag1 = s9 != null
&& (s9.equalsIgnoreCase("yes")
|| s9.equalsIgnoreCase("y"));
I'd would greatly appreciate some help.
Thanks in advance!

Answer 1

One possible reason is that i am using javax.sql.datasource in the source code but the DataSource has been defined with "com.evermind.sql.DriverManagerDataSource" throwing the classcast exception.
any idea in which jar the "com.evermind.sql.DriverManagerDataSource" class can be found ?
