Error executing Oracle function from JSP page

I'm trying to call a stored procedure from a jsp page using the code below,
but I am currently getting the following error message:
"java.sql.SQLException: [BEA][Oracle JDBC Driver]The requested output parameter data is not available."
I am running weblogic 8.1 on my local machine and connecting to an Oracle 8i database.

Can someone tell me why I am getting this error? Thanks in advance for your help!

CallableStatement = conn.prepareCall("{ call ? := Func_Noodle_oqr_one(?,?)}");
st.registerOutParameter(1, OracleTypes.CURSOR);
st.setString(2,"");
st.setInt(3,neuId);
ResultSet rs = (ResultSet)st.getObject(1); // <- The error appears to be occuring at this point
rs = st.executeQuery();
while (rs.next()) {
System.out.println(rs.getString(1) + "\t" +
rs.getFloat(2) + "\t" +
rs.getDate(3).toString());
}

BTW, this is my Oracle function:

Can you try without colon ":" and call your function like this

CallableStatement = conn.prepareCall("{ ? = call Func_Noodle_oqr_one(?,?)}");

Wally

I think it should work, any way I would like to see the modified code can you paste the code snippet for modified here.

Shailesh, here is my latest code:

CallableStatement st;
ResultSet rs = null;
st = conn.prepareCall("{ ? = call Func_Noodle_oqr_one(?,?)}");
st.registerOutParameter(1, OracleTypes.CURSOR);
st.setString(2,"");
st.setInt(3,neuId);
st.executeQuery(); <- also tried st.execute; and without this statement.
rs = (ResultSet)st.getObject(1); // <- error occuring at this point
//rs = st.executeQuery(); <- removed this statement (was setting rs twice)
while (rs.next()) {
System.out.println(rs.getString(1) + "\t" +
rs.getFloat(2) + "\t" +
rs.getDate(3).toString());
}

It should work !!! I dont find any error or we both are missing something.

I suggest you comment after the code st.execute()

and then execute code. tell me if this gives no error.

also tell me error which you are getting.

I was wrong about where the error is occuring in that last post...
It's actually occuring on the st.execute(); statement. This is the error message now: "java.sql.SQLException: [BEA][Oracle JDBC Driver][Oracle]ORA-00911: invalid character".



If I comment out all of the code from before the st.execute(); statement, I don't get an error within this block of code (just an error further down the page because there is no data from the recordset).

Actually, I was wrong again about that error message (I'm trying so many different things, it's getting confusing)...

Using the PrepareCall statement you suggested,
st = conn.prepareCall("{ ? = call Func_Noodle_oqr_one(?,?)}");
I am getting this error:
"java.sql.SQLException: [BEA][Oracle JDBC Driver]Invalid parameter binding(s").

I had temporarily gone back to my previous PrepareCallStatement, st = conn.prepareCall("{ call ? := Func_Noodle_oqr_one(?)}");, which gave me the "java.sql.SQLException: [BEA][Oracle JDBC Driver][Oracle]ORA-00911: invalid character" error I mentioned in the last post.

Sorry about the mixup...

So Wally I prefer with my approcach

st = conn.prepareCall("{ ? = call Func_Noodle_oqr_one(?,?)}");

as I had worked with same code many times

call you function like this

st = conn.prepareCall("{ ? = call Func_Noodle_oqr_one("your value","your value")}");

and only registerOutParameter try if this work.

then remove one argument in code

st = conn.prepareCall("{ ? = call Func_Noodle_oqr_one(? ,"your value")}");

and use

st.setString(2,"");

and find the exact cause of error.

thats what I can think....

Wally, not sure if you have figured this out already. If so then you can ignore this.

Following is the example that I use in one of my projects. Changed SQL and names, but should be simple -

CREATE OR REPLACE PACKAGE Test
AS
TYPE refCursor IS REF CURSOR;

FUNCTION getAssets (instructionId NUMBER, status VARCHAR2)
RETURN refCursor;

END;
/
----------------------------------------------------------------------------
CREATE or REPLACE PACKAGE BODY Test
AS
FUNCTION getAssets (instructionId NUMBER,
status VARCHAR2)
RETURN refCursor
IS
assetCursor refCursor;
BEGIN
OPEN assetCursor FOR
SELECT
a.instruction_id,
a.instruction_type
a.asset_number,
l.lot_number,
l.amount
FROM asset a, asset_lot l
where a.instruction_id = instructionId
and a.asset_status = status;

RETURN assetCursor;
END;
----------------------------------------------------------------------------
END;
/

DataSource ds = (DataSource)ctx.lookup("Oracle_sid");
connection = ds.getConnection();
String storeProc = "{call ? = test.getAssets(?,?)}";
CallableStatement getAssets = connection.prepareCall(storeProc);
getAssets.setLong(2,43544);
getAssets.setString(3,"CLOSED");
getAssets.registerOutParameter(1,OracleType.CURSOR); // -10
getAssets.execute();
ResultSet rs = (ResultSet)getAssets.getObject(1);

In your example I dont think there's any problem in the JDBC code that you have in ya JSP. You can only return REF CURSOR from Oracle to java clients. Your return type cursor is specific, and can only be understood by PL/SQL.

cheers.
