problem with finder method

[vikassheel gupta]

Hi,
i have a problem
when ever i try to map 1:1 relationship at that time when at client side when i call the primary key of other table then the following error occurs
:-
non-static method findByPrimaryKey(java.lang.String) cannot be referenced from a static context

now can any one tell me why this occurs
i shall be thankful to you

[Adrian Bates]

Are you testing this method inside a small test harness? Is the method you are calling static by any chance?

[vikassheel gupta]

ya
i dont have any static method
even i dont have use static keyword
but because of CMP EJB the method i make in home interface automatically becomes Abstract so
i cant understand why this problem occurs

[Adrian Bates]

All methods in the home interface will just be method stubs (i.e. abstract) as this is an interface. The actual class that implements this interface is automatically generated and you don't need to worry about it. This is not your problem.

[vikassheel gupta]

so can you tell me why this problem occurs
and even i didnt use any static keyword
thanks alot

[Roger Chung-Wee]

Please post your code, both client and server.

This is a JSP file and i just give u the code which i use to make relationship




now we have local home and local remote interface too
and the 1:1 mapping bean also with name dodauthorisation

[Roger Chung-Wee]

Surely both your ejbCreate methods must return null.

[vikassheel gupta]

Hi,
The problem is not related to the return type but when ever i call the findByPrimaryKey method in the jsp page finder method of the foreign key table's bean. Then my IDE able to import the class but unable to call the findByPrimaryKey method
so if i forcefuly write this method and compile my program then this error occurs
non-static method findByPrimaryKey(java.lang.String) cannot be referenced from a static context

[sunny sri]

Hi,
make sure that getting the homeobject correctly.

Thankq

[Balazs Borbely]

Cnmas cn= CnmasHome.findByPrimaryKey("101");

You didn't provide any detail about 'CnmasHome', it seams as a static methot call.

[vikassheel gupta]

hi all
thanks alot
i got the solution related to that problem
the solution will be the confinguring foreign key bean in JNDI
i didnt lookup the other bean
so this problem occurs
thanks alot
