Imroove Performance ..reduce the Network trips

Question

Hi !
The application I am working on now basically uses the SAX parser(with Java) to parse XML data and load the data into the database.
The application while parsing an XML file checks to see
if a particular enitity is present in the DataBase(Oracle 9)..(and returns true/false) Since there are more than 10000 records..the process needs to make 10000 network trips and this is slowing down the process.I am using preparedStatemts for this.
The function call is something similar to this...
public static boolean DBCheckIdentifier(String identifier, String tableName) throws Exception {
//.. some code
SELECT count(*) FROM table1, table2 WHERE table1.ID = table2.ID AND IDENTIFIER = ? AND ROWNUM = 1
// executes the prepared statement
Since this is taking most of the time in the application ,I was wondering if there is any way by which I can improove the performance.
There are around 200 different types of Table2's(one of the variable)
Thanks so much ..I appreciate your effort

Hi,
as of now, this is the one i can think of.
Write a stored proc which takes in an Array of identifiers, the stored proc will do the checking and return an array of "true/false" corresponding to the input array values.
