Re: Problem concerning Maven with Hibernate JPA
Unfortunately, I get the an error (see below) when I am creating a jar file and run the program afterwards. As I can see, of course, the javax.persistence jar provided by the ejb3-persistence.jar is obviously missing. But I don't know how to fix the problem. When I'm running the program as a simple Java Desktop App, everything is fine. How are you creating a jar file and run the program? Unless you build a special package eg with the assembly plugin, it will only contain your project code and not the dependencies etc. What are your expectations?

Re: Problem concerning Maven with Hibernate JPA
Hi Wayne, thank you for your answer. I should be more precised in my descriptions... Here are the facts, in hope to give you some hints: - It's a desktop java app - I'm using the m2eclipse plugin - m2eclipse creates a jar file for me to run it as a desktop java app - m2eclipse runs with the goals: goals: compile test-compile test - junit tests work fine (where database stuff is tested) - there's an exec plugin (groupid: org.codehaus.mojo, artifactid: exec-maven-plugin) which executes the jar after building it. The jar principally works, but the first time, I'm using a database related process, I get this error. Hope, that helps - if you need any more information, please let me know. I know about the assembly program and I tried to execute the goal assembly:assembly, but it didn't work... If you need any more information to solve this problem, please let me know.

Re: Problem concerning Maven with Hibernate JPA
- there's an exec plugin (groupid: org.codehaus.mojo, artifactid: exec-maven-plugin) which executes the jar after building it. The jar principally works, but the first time, I'm using a database related process, I get this error. What does your exec-maven-plugin configuration look like? It seems like it does not know about this dependency, so it is not including it in the Java classpath when your program runs which results in the NCDFE. know about the assembly program and I tried to execute the goal assembly:assembly, but it didn't work... You're going to have to do some reading about the assembly plugin to make it work, that's not sufficient.

Problem concerning Maven with Hibernate JPA
Hi, I have only little experience with Maven. Currently, I'm working on a project with JPA. It's a desktop application without Application Server. I added the hibernate-entitymanager-3.4.0.GA.jar to the dependencies (all corresponding dependencies are resolved by Maven). My JUnit tests concerning Hibernate and Entities run fine with no errors (so I guess that Maven principally runs fine). Unfortunately, I get the an error (see below) when I am creating a jar file and run the program afterwards. As I can see, of course, the javax.persistence jar provided by the ejb3-persistence.jar is obviously missing. But I don't know how to fix the problem. When I'm running the program as a simple Java Desktop App, everything is fine. If you could provide me any more information, that would be great. Thanks in advance.

Re: Problem concerning Maven with Hibernate JPA
Martin, While the app I'm currently working on is a web-based app, I have an explicit dependency declare for the persistence API. Whether it is necessary, I'm not sure, but it's in the POM. So, I thought I'd reply with it for you. dependency rgroupIdjavax.persistence/groupId artifactIdpersistence-api/artifactId version1.0/version /dependency I hope this is helpful, Dave Martin Chmielewski wrote: Hi, I have only little experience with Maven.
