hello group-ians ,
I have been doing the my project with hibernate3+jboss4.0.2+jdk1.4.
i have two tables namely product[ prod_code and other columns] and product_release.[prod_code,prod_tag and rel_date]
and i have three classes namely productsBean,productsPKBean(productcode and producttag properties) and productsRelBean.
mapping files:products.hbm.xml and product_release.hbm.xml.
I am using composite primary key(prod_code and prod_tag ) for the table product_release.
i did prod_code and prod_tag as composite id from the productsPKBean class mapping in theproduct_release.hbm.xml file. and i did many to one mapping with productBean (prod_code) . and i put insert=false update =false in many-to-one relationship..
I created three class objects(productsBean,productsPKBean andproductsRelBean) and set the responsible parameters..and save three objects into the hibernate session..
i believe that all things are happened right.
but "save " command is not executed. no error or warning is araised.
everything is fine..
i dont know "what is the mistake i did"?
plz make help me.
here is my code:
