hibernate - Insert persistence record in DB where two table are seprate -

i using struts , hibernate. trying insert data in 2 table independent. if first table insertions create error can not able insert second table data , vice-versa. want this. how can this?

code

public string create() {     getdaofactory().instantiatedao(daoclass).saveorupdate(entity);     getdaofactory().getmatchpredictionoptionlevel2().saveorupdate(                     optionlevel2);    return success:  }  public t saveorupdate(t entity) {         try {             getsessiontx().save(entity);             commit();         } catch (exception e) {             rollback();             e.printstacktrace();         } {             getsession().close();         }         return entity;     }  public session getsessiontx() {         system.out.println("in sassion method getsessiontx");         if (this.session == null)             this.session = hibernateutil.getsessionfactory().opensession();          this.session.begintransaction();         return this.session;     } 

that transactions has been made for.

for instance:

        try{             session = hibernateutil.getsessionfactory().opensession();//<==creade session sessionfactory              tx = session.begintransaction();//<==== start transacton             tx.settimeout(5);             //dosomething(session); if 1 of queries fail insert goes catch              tx.commit();          }catch(runtimeexception e){             try{                 tx.rollback();//<=== you'll rolling previous inserting value in case if 1 failed insert             }catch(runtimeexception rbe){                 log.error("couldn’t roll transaction", rbe);             }             throw e;         }finally{             if(session!=null){                 session.close();             }
