thanks for ur quick response sir i am using this services provided by sun microsystem first time and
am really thankful to Sun Microsystem for this great deal of help to the new commers but sir my problem is still there.
following is the method which i have written in the code
     public InvoicePK ejbCreate(int id)
          this.id=id;
          return null;
and here it is the error generated by the server deployment tool.
[9.2.8] In EJB Invoice, the return type for the create method create(int) must be the bean's remote interface type.
[9.2.8] In EJB Invoice, the findByPrimaryKey method must return the Entity bean's remote interface type.
[9.2.8] In EJB Invoice, the return type for the method findByPrimaryKey(com.swi.InvoicePK) must be the entity bean's remote interface type (for a single-object finder) or a collection thereof (for a mult-object finder).
the detail of files created by me are as follows.
1. Invoice (Entity Bean)
2. InvoicePK (Primary Key file)
3. MyRemoteInterface (remote interface for entity bean)
4. MyHomeInterface (home interface for entity bean)
plz let me know where i am doing wrong and oblige.
