How to update bulk no of records using Batch Update

Question

i am trying to insert and update records into multiple tables using Statement addBatch() and executeBatch() method. But some times it is not executing properly. some tables records are inserting and some tables it is not inserting. But I want all the records need to excute and commit or if any error is there then all records need to rollback.
This is the code i am using.
public String addBatchQueryWithDB(StringBuffer quries, Connection conNew,Statement stmtNew) throws Exception {
String success="0";
try {         
conNew.setAutoCommit(false);
String[] splitquery=quries.toString().trim().replace("||","##").split("\\|");
for(int i=0;i<splitquery.length;i++) {
//System.out.println("query.."+i+".."+splitquery.trim().replace("##","||"));
stmtNew.addBatch(splitquery[i].trim().replace("##","||"));
int[] updCnt = stmtNew.executeBatch();
for(int k=0;k<updCnt.length;k++){
int test=updCnt[k];
if(test>=0){
success=String.valueOf(Integer.parseInt(success)+1);
// System.out.println(".updCnt..."+updCnt[k]);
System.out.println("success...length.."+success);
if(updCnt.length==Integer.parseInt(success)){
success="1";
//conNew.commit();
} catch (BatchUpdateException be) {
//handle batch update exception
int[] counts = be.getUpdateCounts();
for (int i=0; i<counts.length; i++) {
System.out.println("DB::addBatchQuery:Statement["+i+"] :"+counts[i]);
success="0";
conNew.rollback();
throw new Exception(be.getMessage());
} catch (SQLException ee) {
success="0";
System.out.println("DB::addBatchQuery:SQLExc:"+ee);
conNew.rollback();
throw new Exception(ee.getMessage());
} catch (Exception ee) {
success="0";
System.out.println("DB::addBatchQuery:Exc:"+ee);
conNew.rollback();
throw new Exception(ee.getMessage());
}finally {
// determine operation result
if(success!=null && success.equalsIgnoreCase("1")){
System.out.println("commiting......");
conNew.commit();
}else{
System.out.println("rolling back......");
success="0";
conNew.rollback();
conNew.setAutoCommit(true);
return success;
}

Thank you for ur reply,
I am using single connection only, but different schemas. Then I am passing a Stringbuffer to a method, and First iam setting con.setAutoCommit(false); and then in that method i am splitting my queries in stringbuffer and adding it to stmt.addBatch(). After that I am executing the batch.after executing the batch i am commiting the connectionIf I am reading that right then you should stop using Batch.
The intent of Batch is that you have one statement and you are going to be using it over and over again with different data.
