java - two transaction issue with Hibernate 3 -

in our application using hibernate 3. faced 1 issue in transactions. have code in following manner

    method1()     try{     tx = session.begintransaction();     //new object needs stored     session.save(object);     // code generates exception     tx.commit(); // exception occured before commit processing     }catch(exception ex){     e.printstacktrace();     throw e;     }finally{     if(tx!=null && tx.wasnotcommited()){     tx.rollback();     }     } 

i have method same this, called after method in case of exception thrown method.

session same across both of method.

now experiencing if 2nd method executes , commits hibernate transaction, stores data has been saved in 1st method don't want.

i can not share exact code, prepared 1 test method similar issue. database server mysql.

package com.opshub.jobs.core;  import org.hibernate.session; import org.hibernate.transaction;  import com.opshub.dao.core.company; import com.opshub.utils.hibernate.hibernatesessionfactory;  public class test {      public static void main(string[] args) throws exception{         session session = hibernatesessionfactory.opensession();         try{             transaction tx = session.begintransaction();             try{                 company company = new company();                 company.setname("gaurav");                 company.setcompanydetails("it company");                 company.setcompanyaddress("india");                 session.save(company);                 if(true)                     throw new exception("now go finally");                 tx.commit();             }catch(exception e){                 throw e;             }finally{                 tx.rollback();             }         }finally{             transaction tx = session.begintransaction();             tx.begin();             company company = new company();             company.setname("gaurav 1");             company.setcompanydetails("it company");             company.setcompanyaddress("india");             session.save(company); //          if(true) //              throw new exception("now go finally");             tx.commit();         }     }  } 

any appreciated.

finally found solution issue. before starting transaction/operations can use session.clear() removes pending save/update/delete operation session.

so in rollback, add session.save().

thanks responses.
