Re: getting ClassCastException when trying to remove CMP through Session Facade

[Brian Szucs]

Thanks for replying thorick. I have tried what you said and now all day I have been trying to hunt down the following:

BEA-010054 is stating that my facade and entity bean home, the actual bean and the remote interface are in the classpath and should only be in the ejb-jar file( I can't figure it out)

BEA-010202 Call by reference is not enabled for the EJB

If I can't figure this out I think I am done with CMP EJB's. If I have these sort of problems with live code I will be fired instantly. I am researching to port all of our client/server code done in Oracle Forms (one of which I absolutely hate) to a more generic java platform. I am using JBuilder 9 and have become comfortable with it but if JBuilding is the problem and you are aware of such things please let me know and I may be willing to research something else. Although that may be a problem because of all of the licensing we already bought. Anyhow it seemed as if WLS integrated nicely with JBuilder an the other servers I tried pretty much stopped right there.

HHHHEEEEEEELLLLLLLLPPP

Hi,

BEA-010054 probably means that the jar with your app
is in the SERVERCLASSPATH. This will not
interfere with your testing, but could
become an issue when dynamically undeploying
and redeploying.

BEA-010202 is saying that the EJB container is complying
with the J2EE specification and is treating
remote calls as remote calls (and not as a
local call).

Now the biggie. I'm guessing that what has happened is that the <order-database-operations> and <enable-batch-operations> tags are not in the expected place in your
weblogic-cmp-rdbms-jar.xml file. The line in the error
message:

The content of element type "weblogic-rdbms-jar" must match "(weblogic-rdbms-bean+,weblogic-rdbms-relation*,order-database-operations?,enable-batch-operations?,create-default-dbms-tables?,validate-db-schema-with?,database-type?,default-dbms-tables-ddl?,compatibility?)"..

shows the *exact* order that the xml elements must appear
in the xml file. Can you verify that the new elements are indeed where they should be. This is the most likely cause.

On the subject of ease of development/deployment, there are numerous tools available to make this job simpler (such as the ejbgen tags which will automatically create these pesky deployment descriptors for you). I realize that you are under time pressure to get some results. Just want to say that there are tools out there to ease the frustration.

Let us know how it goes.

thanks
