java.sql.SQLException: Parameter missing IN or OUT index: 2

i got an error: java.sql.SQLException: Parameter missing IN or OUT index::2 in this bellow code

But when I put the value in code I get the error java.sql.SQLException: Parameter missing IN or OUT index:: 1

The Query class is from a framework, but the error happens when execute rs = stmt.executeQuery(); inside Query class as normally Statement...

The database is oracle9i, but I'm using oracle client 10. I don't know if it can cause issues....

Someone have an indea what can be happening ?
