Hi,
I have a datasource whose URL etc values are set at rutime in code using
reportEngine.getConfig().getAppContext().put(propName, propValue);
This works fine for tables and charts but when I create a datacube and crosstab (in tomcat) it falls over with
/olap/cube_Data Cube doesn't exist ( 1 time(s) )
detail : org.eclipse.birt.report.engine.api.EngineException: /olap/cube_Data Cube doesnt exist/olap/cube_Data Cube doesn't exist at org.eclipse.birt.report.engine.executor.ExecutionContext.add Exception(ExecutionContext.java:1109
In the tomcat log I can see
03-Dec-2009 11:41:15 org.eclipse.birt.data.engine.odaconsumer.ConnectionManager openConnection
SEVERE: Cannot open connection.
org.eclipse.birt.report.data.oda.jdbc.JDBCException: There is an error in get connection, No suitable driver found for localhost.
Futher in the log there is an error (though I think this is caused by the connection error):
java.lang.ClassCastException: org.eclipse.birt.report.engine.content.impl.ForeignContent cannot be cast to org.eclipse.birt.report.engine.content.IDat

It seems it cant find the driver for some reason. I know the driver is there as same datasource works for chart/tables. There are similar threads about this:
http:// www.eclipse.org/forums/index.php?t=msg&goto=362063&S =5ff96d04721ef8f261f33d7d2de754b2
the datacube and crosstab work perfectly if I explicitly specify the database details in the datasource itself, so it must be related to the setting of them using ReportConfig, but since they are set only once and works the chart and table....?
Does anyone have any idea whats going on?
thanks

If you hard code the driver url instead of using:
reportEngine.getConfig().getAppContext().put(propName, propValue);
Does it work. This may be a bug with the cube engine not having access
to the app context. What version of BIRT are you using?

Any chance you can try this with 2.5.1 before logging a bug.

Trevor,
You can log the bug on 2.3.1 but I doubt the fix will get back ported.
The INFO you are getting in the log should not cause any issue, but it
would be good to add it to a bugzilla entry.
