I am getting the following error in the console when launching my app using Java Web Start (runs fine from the desktop). My JNLP file has

<security>
<all-permissions/>
</security>

I am using EntityManager 3.2.0 CR1 , Hibernate Core 3.2 CR2, Annotations 3.2.0.CR1.

Is there a help page for using Web Start with Hibernate EJB3 Persistence? Why is it unable to read my jar from the cache -- is Hibernate doing some file access that is outside of the security allowed by web start? Thanks,

Mark

I think that almost in all cases you need a certificate. And <all-permission> is not replacing that. I think it just says when you are certified, that you can do whatever you want.
If you look at the cause - it is thrown when looking at the File - permission to browse your file system. That definitely needs authorized permission.

I did a couple of JWS and I always had certificate - mostly made my own with keytool.

Hello Ales,

Do you mean that you sign the jars before deploying them? I am doing that. I've used web start successfully before, but after migrating over to Hibernate persistance I am getting this error.

After clearing out my web start cache and trying again, I'm actually getting a different error now. Has anyone been able to successfully deploy an app using EntityManager 3.2.0 CR1 and JWS? It would be nice to know if it has been done. Thanks,

Mark

I'm trying to isolate the problem. I am using the following seemingly simple code snippet. Is there a problem referencing the META-INF/persistence.xml file through ClassLoader.getResource() in JWS? I've spent a good day on this now, if anyone can at least give me a "yes, I've done it, it should work", at least I'll know that it's possible. Otherwise, should it be submitted as a JIRA issue with Hibernate EntityManager? Thanks,

Mark

EntityManager em;

try {
// get a new entity manager factory
Map<String, String> properties = new HashMap<String, String>();
properties.put("hibernate.connection.driver_class", "net.sourceforge.jtds.jdbc.Driver");
properties.put("hibernate.connection.url", "jdbc:jtds:sqlserver://dbserver/testdb;tds=8.0;lastupdatecount=true");
properties.put("hibernate.connection.username", "xxxxxxx");
properties.put("hibernate.connection.password", "xxxxxxx");
properties.put("hibernate.show_sql", "false");
EntityManagerFactory emf = Persistence.createEntityManagerFactory("ejb-test", properties);

// test properties
em = emf.createEntityManager();
Query q = em.createQuery("select a from Account a where a.id = 10");
List<Account> list = q.getResultList();
Account a = list.get(0);
em.close();
System.err.println("list size = " + list.size());
System.err.println("accountType = " + a.getAccountType());
System.err.println("name = " + a.getName());

// close the factory
emf.close();
}
catch (Exception e) {
throw new RuntimeException(e);
}

which produces the following exception in Java Web Start (works fine from desktop):

Any solution or suggestions to this issue? The application eventually executes after minutes, but I'm getting errors.

I'm Running:

INFO: Hibernate Annotations 3.4.0.GA
INFO: Hibernate 3.3.0.SP1
INFO: hibernate.properties not found
INFO: Bytecode provider name : javassist
INFO: Hibernate Commons Annotations 3.1.0.GA
INFO: Hibernate EntityManager 3.4.0.GA

I signed my jars and added the security tags to my jnlp file:
<security>
<all-permissions/>
</security>

I'm having a similar problem. My app functions properly if I run it locally with javaws, but if I post it to a site and launch it from the site I get the error:
