Re: Java and COBOL stored procedures

["Richard Dettinger" <cujo@xxxxxxxxxx>]

You can't pass an Array as a parameter in Java.  Well, Java 2 has support
for the SQL datatype ARRAY in the getArray/setArray methods, but this is
not the same thing, and the 400 doesn't support ARRAY data types today.

There are ways (which I am not too up on personally) to return an array as
a ResultSet.  I know this can be done from C, I assume it works from other
languages as well.  In that model, the StoredProcedure returns the
ResultSet and then you process it exactly as if it was an open database
cursor coming back.   Perhaps there is a solution somewhere down that path
for you.

Subject:  Java and COBOL stored procedures



I'm experimenting with calling COBOL stored procedures from Java programs
and have successfully used "getString" to return character variables from
the procedure.
Is it possible to return an array? Or do I have to return a really large
CHAR variable and have the Java program break it up?

On a different note, is there any way for a servlet to call a stored
procedure and pass a reference to the PrintWriter variable, so that the
called program could write directly to the HTML output stream?

Thanks in advance!
