Hi,
i try to use the source code of the book but i always have the following errors:

Code:
C:\sources - java persistance with hibernate\jpwh-gettingstarted-061110\hellowor
ld-jpa>ant run
Buildfile: build.xml

compile:

copymetafiles:

run:
     [java] Exception in thread "main" javax.persistence.PersistenceException: N
o Persistence provider for EntityManager named helloworld
     [java]     at javax.persistence.Persistence.createEntityManagerFactory(Pers
istence.java:55)
     [java]     at javax.persistence.Persistence.createEntityManagerFactory(Pers
istence.java:33)
     [java]     at hello.HelloWorld.main(Unknown Source)
     [java] Java Result: 1

BUILD SUCCESSFUL
Total time: 1 second
C:\sources - java persistance with hibernate\jpwh-gettingstarted-061110\hellowor
ld-jpa>



Apparently my helloworld class don't know how to access the persistence.xml file..
Do you know how to solve this problem ?
Thanks

Hi I got the same error !
Well i was missing few jars in the class path . But it took hell lot of time for me as it is was not complaining about the missing Jars but it keep saying
"No Persistence provider for EntityManager named helloworld".
So I assume if you are trying this sample from the previous one you obvioulsly missed the following jars like me.
Jars files required (which i missed in my classpath.)
javaassit -
jboss-archiving-
hibernate-entitymanager-

if we still getting error u can download the source code and in the lib directory u can find all these jars..
I too downloaed from there but i was tryign to add the jars only when required.And the error message obviously did not helped in any way.

Hope this will solve your problem.
Regards,
Vinodh..[[/b]

All Jars required are as shown below
    \antlr-2.7.6.jar
    \asm.jar
    \asm-attrs.jar
    \c3p0-0.9.0.jar
    \cglib-2.1.3.jar
    \commons-collections-2.1.1.jar
    \commons-logging-1.0.4.jar
    \dom4j-1.6.1.jar
    \ejb3-persistence.jar
    \hibernate3.jar
    \hibernate-annotations.jar
    \hibernate-entitymanager.jar
    \hibernate-tools.jar
    \hsqldb.jar
    \javassist.jar
    \jboss-archive-browsing.jar
    \jta.jar
    \lgpl.txt
    \log4j-1.2.13.jar

Please use the release from December 11th, not the one from November.

The exception
Code:
javax.persistence.PersistenceException: No Persistence provider for EntityManager named ...
comes because class org.hibernate.ejb.XHibernatePersistence is not found (?), the package hibernate-entitymanager.jar is not on the classpath.

The easiest way to get the missing jar's is to dowload Hibernate EntityManager and copy them from the /lib.

If the persistence provider jar and/or class is missing, the thrown exception is not classNotFound but this 'PersistenceException: No Persisten provider ...'
There seems to be various ways to get this exception.

Having continued on the learning curve I notice that in my previous mail the question mark after the classname
Code:
org.hibernate.ejb.XHibernatePersistence
was more valid than I knew. The correct classname, which is given in persistence.xml is
Code:
org.hibernate.ejb.HibernatePersistence
No capital X in front of Hibernate. That was my typo, in book the classname is correct.

It's OK for me.
I forgot to copy hibernate-entitymanager.jar into lib directory.

Hi all,
I`m getting exactly the same error. I have all listed jars from latest builds in place and persistence.xml file in META-INF directory but I`m running my test client as a standalone app without any Apllication Server. Is that a problem or I have to do some more steps?
Has someone tried to use Hibernate EntityManager as a part of standalone app?

regards,
vs

If you download the Hello World package, and if you follow the README instructions step by step, is there a problem or does it work?

If your question is not about the Hello World package, but about Hibernate EntityManager in general, you are in the wrong forum.

Are you talking about the Hello World package for the book or are you in the wrong forum like the previous poster?

\jta.jar
\lgpl.txt
\log4j-1.2.13.jar




Add this tag <provider>org.hibernate.ejb.HibernatePersistence</provider> in your persistence.xml .Finally copy persistence.xml in META-INF folder. It will work .
