Hello,
i have trouble using the Java Methode Call Data Source. I found some posts related to this, but nothing realy helped.
My Java code is simply:
My Query in the Java Methode call window is:
de.spektra.infraview.statistics.Java2Pentaho#getTable("Hello","World")
The response is
java.lang.NullPointerException: hello: null world: null
So the problem is that i don't receive any parameters.
I also tried to generate pentaho parameters and pass them into the query:
Add Parameter:
- Name: var1
- Value Type: String
- Default Value: Hello
Add Parameter:
- Name: var2
- Value Type: String
- Default Value: World
query: de.spektra.infraview.statistics.Java2Pentaho#getTable(var1,var2)
i also tried with ""s around the values and with hidden parameters. Nothing seems to work.
Any help would be appreciated!
