NameNotFoundException when looking up DataSource in new Thread

Question

I am trying to run a db procedure in a new Thread within a J2EE app. The actual code to run the procedure is in a class that is called from a JSP page, a controller if you will (not a servlet). When I start the new Thread and try to get a connection from my DataSource, I get a NameNotFoundException. We are using iPlanet and Oracle. Is it a bad idea to start a new Thread from within iPlanet? Is there another way to run the db procedure and not make the user wait for it to finish?
Any help/suggestions would be greatly appreciated.

Answer 1

Okay, here is my Runnable class.
<code>
public class ExtractRunner implements Runnable, Serializable
Extract m_extract;
String m_propfile;
String m_modName;
LogManager m_log;
public void run()
DBConnectionManager conMan = null;
try
conMan = new DBConnectionManager(m_log.getElectronicServicesLog(),
m_propfile, m_modName, "");
int result = m_extract.doExtract(conMan, m_log);
catch (Exception e)
e.printStackTrace();
finally
m_extract = null;
if (conMan != null)
conMan.release();
conMan = null;
m_log = null;
ExtractRunner(Extract extract, String propfile, String modName, LogManager log)
m_extract = extract;
m_propfile = propfile;
m_modName = modName;
m_log = log;
</code>
Here is the code that starts the thread. It is in another class that is called from the JSP.
<code>
public int doExtract(Extract extract)
ExtractRunner er = new ExtractRunner(extract, PROP_FILE, MOD_CODE, m_log);
Thread t = new Thread(er);
t.setName("ExtractRunner");
t.start();
return 0;
</code>
And here is the code that calls the db procedure. It is in the Extract class.
<code>
public int doExtract(DBConnectionManager dbConnMgr, LogManager log)
DBProcedureStatement dbStmnt = null;
DBQuery dbQuery = null;
Vector rs = null;
int sqlResultCode = 0;
dbStmnt = new DBProcedureStatement(this.getExtractProcedure());
dbStmnt.addParameter(this.getParameters());
try
dbQuery = new DBQuery(dbConnMgr);
long start = System.currentTimeMillis();
log.logDebug("ExtractRunner::run()", "debug",
"Starting extract at " + start);
rs = dbQuery.doProcedure(dbStmnt);
long elapsed = System.currentTimeMillis() - start;
log.logDebug("Extract::doExtract()", "debug",
"Done with extract." +
" Elapsed time(ms): " + elapsed);
if (rs != null && !rs.isEmpty())
sqlResultCode = ((BigDecimal)rs.elementAt(0)).intValue();
log.logDebug("Extract::doExtract()", "debug",
"Result = " + sqlResultCode);
//System.out.println("REsult code: " + sqlResultCode);
else
sqlResultCode = GEN_ERROR; //Procedure error
sqlResultCode = 0; // The extract is no longer returning a result code
// so if there's no Exception return SUCCESS
catch (Exception e)
log.logError("Extract::doExtract", "FDE_LOGGING",
"Error doing extract. Exception: " + e);
e.printStackTrace();
sqlResultCode = GEN_ERROR;
finally
DBUtil.releaseResults(rs);
//sql = null;
rs = null;
dbStmnt.finalize();
dbStmnt = null;
dbQuery = null;
log.logDebug("Extract::doExtract", "FDE_LOGGING",
"END: Results: sqlResultCode=" + sqlResultCode);
return sqlResultCode;
