Dear All,

I am facing a strange problem (net.sf.hibernate.MappingException: No persister for: java.lang.Boolean) while committing my persistent class. I used transaction.commit();

Note: Please see below for exact exception message.

Your quick help is highly appreciated.

Thanks

net.sf.hibernate.MappingException: No persister for: java.lang.Boolean
at net.sf.hibernate.impl.SessionFactoryImpl.getPersister(SessionFactoryImpl.java(Compiled Code))
at net.sf.hibernate.impl.SessionImpl.getClassPersister(SessionImpl.java:2656)

show the full stacktrace

I've seen a solution in http://www.c2b2.co.uk/iPoint/ipoint?SelectedPage=58. But it was working for me earlier on JDK 1.4 itself.

FYI, I am using IBM WSAD 5.1 as IDE.

Please see the complete stack trace below

Thanks

Sorry to confuse you. The link http://www.c2b2.co.uk/iPoint/ipoint?SelectedPage=58 says that the problem is related with JDK version.

so you have a value that is a Boolean instead of being an actual reference to a persistent class....

No, It is not Boolean. I am able to print the persistent object and it's member variables in the debug logger message before committing it and Hence it is not a Boolean.

- Raza

ok if you don't belive me then step through the code its opensource.

My code goes something like this

session = PersistenceSessionFactory.getSession();
transaction = session.beginTransaction(); //
Account acc = (Account) session.load(Account.class,ID);// This Account is my actual persistent object.
acc.setXYZ(100);
acc.setABC("test");
id = (Integer) session.save(acc); // This tries to save my acc object to DB.
transaction.commit(); // Here is where I get the exception.
session.close();

I am getting the exception when I do transaction.commit. I am able to print acc.toString() as logger message just before doing transaction.commit.

Please help out.

Thanks
Raza

yes and you have probably mapped a boolean field to another class/entity in Account.

check your mappings...

Probably that could be the problem. Because I've created a new sample persistent class and tried updating the object. It worked for me.

Thank you Max. I will work on the this exception and let you know the updates.

Thanks to hibernate team as well.

- Raza.
