OracleXMLQuery generates java.lang.OutOfMemoryError

Question

Hi all,
I am using OracleXMLQuery( ) to generate XML file from the contents of a table. I have almost 30000 rows in the table with each row containing 30 columns.
The code to fetch the data and form an XML File goes like this
st_CountRowsInView = conn.createStatement();
outputFile = new File(outputFilePath);
outputFile.createNewFile();
outFile = new FileWriter(outputFile);
sqlStatement = "select * from " + viewName;
qry = new OracleXMLQuery(conn, sqlStatement);
qry.keepObjectOpen(true);
qry.setRaiseException(true);
qry.setRowsetTag("RowSet");
qry.setEncoding("UTF-8");
qry.setDateFormat(dateFormat);
//Make the rowtag equivalent to the alias name
qry.setRowTag(aliasName);
qry.setRowIdAttrName(null);
qry.setRowIdAttrValue(null);
outFile.write(qry.getXMLString());
qry.close();
outFile.close();
The above code works fine when there are 100 records. But the same code throws outOfmemory error when the number of rows increases. Kindly help me to rectify the problem.

Issues related to pre 9.2.x database are not discussed in this forum. Please read the forum introduction for details for which forums should be used to discuss XML processing in legacy databases.
If you have the option of upgrading to database 9.2.0.3.0 or later I would start by reading the XML DB application developer's guide for the topics I mentioned in my earlier post
