JSP and CLOB's

Question

Has anyone got CLOB data from a column to a JSP page?
I have tried many options and seem to always get the 'stream closed' errror.
Clob outClob = ((OracleResultSet)reset.getClob("column_name");
I tried a Reader etc. No luck.
I am using Tomcat, and oracle 8.1.6

Hi Mark,
try this code:
public void dumpClob (JspWriter out, CLOB clob) throws Exception {
// get character stream to retrieve clob data
InputStream instream = clob.getAsciiStream();
// create temporary buffer for read
byte[] buffer = new byte[10];
// length of characters read
int length = 0;
// fetch data
while ((length = instream.read(buffer)) != -1) {
               for (int i=0; i < length; i++) {
     if (buffer[i] == 13 || buffer[i] == 12) {
     // out.print("<BR>");
                         out.print((char)buffer);
     else {
     out.print((char)buffer[i]);
out.flush();
instream.close();
And in the jsp:
<%
dumpClob(out,(oracle.sql.CLOB )rs.getObject("field"));
%>
I hope this helps you!
