Transaction Demarcation Home Interface FAILED

[Micheal John]

I am trying to run a sample program in entity. But While I am verifying with verifier, it encountered one error. How to resolve this error?

And in HFEJB, they have mentioned step-by-step screen shots for session beans, but didn't specify for entity bean??

For [ CustomerBean ]
Error: Transaction attributes must be specified for the methods defined in the remote interface [ headfirst.Customer ].  Method [ getCustId ] has no transaction attribute defined within this bean [ CustomerBean ].

Are you using the Deploytool ? It sometimes plays bad tricks on me. When I encounter this kind of error, I go to the Transaction settings tab, and select the method it is complaining about.
In your case, go to the Transaction settings, and reselect Required for getCustId(). Then save and reverify. It should stop complaining

[Micheal John]

Yes, I am using deploytool. And you are correct, I have just clicked the Requied drop button once again and it has been verfied succesfully.

But when i tried to deploy, it has asked for:

Application: CustomerApp
SQL has not been generated for the following EJBs:
CustomerBean
Do you want to continue?

I have given "yes".

While deploying I am getting the following errors:

There was a deployment error
java.rmi.ServerException:RemoteException occured in server thread;nested exception is:java.rmi.RemoteException:Error processing ejb jar:Compilation failed.
Please refer to log file:

In the Log file:

How to resolve this error?

Can we write DD manually, and deploy it in J2EE Server? How to do that?

You need to generate the SQL statements from the Deploytool.
In the entity beans properties, theres a tab for that, I forgot which one (sorry I'm not using my development computer now)

You will need to run Cloudscape first, from the command line.
In the j2ee/bin directory, I think it was "cloudscape -start".

Then you'll have to tell the Deploytool the JDBC connection settings. Once done, you can press the "Autogenerate button" and it will generate all the necessary SQL statements for Cloudscape.

Sorry that I can't explain in detail now. I hope you can figure it out.

[Micheal John]

I have started the J2EE Server and cloudscape. Actually, I tried to connect to oracle database. But for a demo purpose I will go with cloudscape. But I don't know the username and password for clouscape and how to use it.
After verified by the deploytool, there ia tab "Entity". In it, there are two buttons: Finder/Select Methods... and Deployment Settings..
I have clicked Deployment Settings button and in it, I have checked Create table on deply and Delete table on Undeploy and the radio button is checked for Remote Finders.
I have clicked Generate Default SQL.
But I am getting the below error:

ERROR:while generating SQL.
java.rmi.ServerException: RemoteException occured in sever thread; nested exception is:
java.rmi.RemoteException:Error connecting to database;nested exception is:
javax.naming.NameNotFoundException: CustomerDB_pm not found
Please make sure the database name/user/password is valid
and the J2EE server and database are running.

I have tired with clicking Database settings, it ask for Database JNDI name, user name and password..?I don't what to fill in it..?

Please help to resolve this issue..

Anyone having any likns/docs on step-by-step procedure for deploying and running entity bean either with oracle/cloudscpae..?

The default user for Cloudscape is scott/tiger. JNDI name : jdbc/DB1

[Micheal John]

Thanks for your help!! I have used the JNDI, user name and password as such given by you, but when I tired to deply some other error is coming. But I have verified it without any errors:

I think that the Deploytool has problems generating his class files. Maybe you've got something wrong in your descriptor. Also check that everything remote is remote, and everything local is local.
