Uregent --Help with Custom Finder

[dhanu varma]

Hi ,
We are using WS v5.1.1 and EJB 2.0 .In our project we have to use db-tables which are present in the same database but doesn't have the corresponding entity beans.If I write a EJBQL finder query for accessing that table(ProductInfo)

Select object(o) from ShowRoom o where o.pid in(select p.id from ProductInfo p where p.name='abc')

I get the following error --abstract schema ProductInfo not defined.
Productinfo has schema mapping with the entity bean in a different ear file deployed as a different project.I am able to access all the entities from this ear file from my project but cann't use the tables from the other project to query .

Is there any way I can query these tables from my project without creating corresponding entities for them.

with our EJB 1.1 we had the flexibity of querying any table with or without corresponding entity using the WhereClauseFinderDescriptor .Does EJB 2.0 have any of that features in EJBQL.

Thanks in advance

Hi dhanu9uk,

Welcome to JavaRanch, the absolute best site on the www for Java information. We don't have many rules around here, but we do have one. Please change your display name to a first and last name to comply with the JavaRanch Naming Policy. You can change it here. Thank you for your cooperation.

Nope, sorry. EJB 2.0 limits the scope of EJB-QL finder queries to the same EJB-JAR file. You're going to have to copy your EJB's (and more importantly, their deployment descriptors) into your second JAR file to make this work.

Hi Kyle thanks for the reply.

I cannot import the other project and its deplyoment descriptor into my first project.Is there any way I can query the tables in the DB (like using finder Interface or some other options).


Thanks in advance.

dhanu, you're still not complying with the naming policy... It requires a first name and last name.
