remove method

[pmsudha]

can we call remove method in persist?

I got an error like


"deleted entity passed to persist: [com.sans.erp.entity.StockDetail#<null>
"

        @SuppressWarnings({ "unchecked", "deprecation" })
     @Override
     public String persist()
     {
         -------
         --------
          shome.getEntityManager().persist(st);
          shome.getEntityManager().flush();
            if(----)
             {
               sh.getEntityManager().remove(sto);
          System.out.println("remove method called");
          sh.getEntityManager().flush();
              }
            return "persisted";

        }

Hi
1. your question should be can we call remove after persist?
2. st is equal sto?
3. what is shome and sh using entity manager?

please post well formed source code.

Hi this is my code...

"@SuppressWarnings({ "unchecked", "deprecation" })
     @Override
     public String persist()
     {
                        -------
                        ------
                    StockDetailHome shome=new StockDetailHome();
               StockDetailList u1=new StockDetailList();
               StockDetail st=new StockDetail();
               String sti=u1.getStockAutoId();
               System.out.println("St_Id:"+sti);
               st.setStockDetailId(sti);
               st.setLocation(to);
               st.setReorderQty(5);
               st.setQuantity(getInstance().getQty());
               ItemDetails ii=new ItemDetails();
               ii.setItemCode(itemcode);
               st.setItemDetails(ii);
               shome.getEntityManager().persist(st);
               shome.getEntityManager().flush();
               
               String qu="select stockDetail from StockDetail stockDetail where quantity=0";
               List<StockDetail> ls=getEntityManager().createQuery(qu).getResultList();
               if(ls.size()!=0)
               {
                    for(int i=0;i<ls.size();i++)
                    {
                         System.out.println("Going to delete");
StockDetail sto=new StockDetail();
sto=ls.get(i);
StockDetailHome sh=new StockDetailHome();
                         sh.getEntityManager().remove(sto);
                         System.out.println("remove method called");
                         sh.getEntityManager().flush();
                         System.out.println("Deleted");
                    }
}
                    
               
          
}     
          return "persisted";
     }"
