Code:

Means that you have a colum "primary_key" in your DB and that you map it to an attrbiute names "primary_key", therefore Hibernate expects to find a getter getPrimary_key() or (getPrimary_Key ??)

You should use Java naming conventions and name this attribute primaryKey and have the getter named getPrimaryKey().

actually i have mentioned that in mapping file under the table1 one as

Code:

i have corresponding getter for that having same datatype but still it is giving me a problem...

I don't get what you mean, could you should your Java classes ?

Okay now I think I get it. In you SectionMaster mapping you've got :

Code:

<many-to-one name="catalogueId"
            class="beans.master.CatalogueMaster"
            column="catalogue_id"
            not-null="true"/>

Which means that SectionMaster has an attribute named catalogueId and whose class is CatalogueMaster. In your SectionMaster class file, this attribute is an int.
