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.

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.

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
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. javax.persistence persistence-api 1.0 I hope this is helpful, Dave Martin Chmielewski wrote: Hi, I have only little experience with Maven.

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.
