Returning a node value from a BPEL process in a JSP.

Question

HI,
I have a problem in that I want to extract the value of a node ie /auto:loanOffer and display it in a JSP.
Could you possibly tell me if I should use
com.collaxa.xml.XPathUtils.selectNodes or getVariableData or something else.
If possible, could you provide a sample code snippet as I am new to jsp/bpel.
Thanks alot
Joel.

Use a result set that returns 1 column that is a clob: Sample code below:
create table tData (xId number, xData clob)
CREATE OR REPLACE PACKAGE clobTest AS
type typeRefCursor is ref cursor;
FUNCTION getData(pId in varchar2) RETURN typeRefCursor;
END;
CREATE OR REPLACE PACKAGE BODY clobTest AS
FUNCTION getData(pId in varchar2) RETURN typeRefCursor is
cursor cData is
select xData
from tData
where xId = pId;
dataLob clob; -- holds the data from the table
outLob clob; -- hold the return data
rc typeRefCursor; -- return ref cursor
BEGIN
-- prepare the output lob
dbms_lob.createTemporary(outLob,TRUE);
dbms_lob.open(outLob,dbms_lob.lob_readwrite);
-- write the start of the output data
dbms_lob.writeAppend(outLob,13,'<data value="');
-- get the data from the table
open cData;
fetch cData into dataLob;
if (cData%found) then
-- append the data to the end of the output lob
dbms_lob.copy(outLob,dataLob,dbms_lob.getLength(dataLob),dbms_lob.getLength(outLob)+1,1);
end if;
close cData;
-- write the closing data tag
dbms_lob.writeAppend(outLob,9,'"></data>');
-- now return the ref cursor with a single column as the lob
open rc for select outLob from dual;
return rc;
END;
END;
Sample code and everything! YOu can buy me a drink next time you're in Chicago.
