JRun connecting DB2 on the mainframes

[KannanPerumal]

One of my application team is trying to build JRun to access DB2 V7.x database
on the mainframes. (OS/390, z/OS ).
They are able to connect to mainframes, but when they query they are getting
message something like this:

java.sql.SQLException: [Macromedia][DB2 JDBC Driver]Invalid parameter
binding(s).

I worked in mainframes all the time. I would like to know where the problem
is. Any lead or pointers or documention will be greatly appreciated. Thank you!
