I have two session beans, they are StudentFacade and SchooldtFacade both of them Stateless, Remote. What I need is call StudentFacade method from SchooldtFacade and vice-versa. Below show how I did it.

I developed simple EJB application, in that application I used Jndi-name as DefaultDS It worked perfeclty no exceptions and data goto database now I want to change Default jndi-name to another name like (mySource) if i change it to mySource i got exceptions. below show technologies I used .

EJB3, Netbeans 6.9 IDE, Mysql 5.1, Jboss 5.1 and Ubuntu 9.1

I copy mysql-connector to jboss-5.1.0.GA/server/default/lib this folder, and remove -ds.xml files in jboss-5.1.0.GA/server/default/deploy and put mysql-ds.xml to it.


Here it contain mysql-ds.xml

Please help me to do it. i suffered Internet but unable to solve the problem, Is their any other files should i changed in Joss to this? I'm waiting for you're precious reply's.


Thank You.
9 years ago
I'm working with mysql 5.1 / glassfish v2 .1 /EJB3/JDK6
I want from a nativequery read a field of CHAR(n) in a database, when I user varchar , it s works, but if i use char(n), I always get a Character instead of a String.

When i user native query to retrive data then I get a java.lang.Character instead of a String.



How can solve this. please help me if this can't i have to change whole database architecture. Therefore I should do this.
Thanks for reply, so I want to create outer join but that table(secondary) haven't relation with main table, In that case how can I create it.
Below show my query, In here main table is "Account" , Joining table is "Customer". How can I write left outer join.



Account Entity




Customer Entity



Please How can I resolve it.
Thank You.
According to your post , you have mention that without locking can be achieved the optimistic locking - please give me some reference link.
In a mission critical system like a banking system how to handle the concurrent access like this;

User A :- Get the particular account record and watching it.
User B :- At the same time get that record and change it committed.
User A :- Now change the account record and committed.

Using version concept(Only Version annotation without em.lock) can we eliminate the concurrent problem?



I have big problem in my application that is concurrency issue(stop simultaneous data update). I'm new to Database locking after reading EJB3 in Action book I decided to use optimistic lock for handle this issue, below show my code I'm using CMT. It seems to be not handle concurrency issue. I looking example in internet more that one week but still I'm fail. Please guide me to solve this issue (If you can provide sample example it's great help to my studies). I'm using mysql 5.1, Glassfish 2.1, Netbeans 6.8 in Ubuntu 9.10 environment. I also added version annotation in my entity class.



please give you're precious comments.
Marembo Ochieng' I think you're wrong

1) @TransactionAttribute(TransactionAttributeType.REQUIRED) use in Container Manage Transaction not User Manage Transaction

2) If I use TransactionAttributeType.REQUIRED - If the method is invoked from a nontransactional client, the container will start a transaction before the method is called and finish it when the method returns. On the other hand, if the caller invokes the method from a transactional context, the method will join the existing transaction. Two Transaction not happen -- according EJB3 in Action book page 219

3) I don't think Container Manage Transaction not handle Database locking automatically if this true please provide such links.

Please give you're precious comments if I wrong or write.

I'm totally confused , if I change persistent provide Toplink to Hibernate work fine why ? please give me comments
I'm using Container Manage Transaction(CMT), below show my entity class

Role.java




Update method



After execute above method earlier mention exception happen. My role table contain only one recode and all columns data equal to 1. please help me to overcome this problem.
Without query.executeUpdate(); every thing work fine if I put query.executeUpdate(); exception happen
