Re: JPA: adding entities to EntityManagerFactory programmatically

HURRAY, the example is working! But making the same changes to my PDE TestCases fails. I am pretty sure this is because of different class loaders. Is it possible to also specify a distinct class loader for each entity class? Background: I am running in an OSGi environment in which the code

Using persistent entities as query parameters

Hi, let's assume this object model: * a person has a address (one-to-one) * a person has many bankaccounts (one-to-many) Let's say person1 and bankaccount1 are persistent entities of their respective types. This query works like a charm: Query query = entityManager.createQuery("SELECT p FROM Per

Re: Using persistent entities as query parameters

Try "SELECT p FROM Person p WHERE :account member of p.bankAccounts". Should work. Cheers, Matthias [EMAIL PROTECTED] wrote: Hi, let's assume this object model: * a person has a address (one-to-one) * a person has many bankaccounts (one-to-many) Let's say person1 and bankaccount1 are persist

connecting to the db

Hi, Is there a way to connect to a db that's already running without attempt to reboot it. I have two services and I would like my second service to connect to the db that already running. But I get the following errors each time my second service attempts to run. Caused by: java.

ArgumentException

Hi! I get a strange exception from time to time at start-up of my application. Sometimes the same code works without problem. What does the exception mean? I do not understand why NavPoint is not recognised as the error-message says that NavPoint is a known entity name? SCHWERWIEGEND [org.openide

maven2 repository and poms

Hi I just noticed that some one recently removed the openjpa 1.1.0 snapshot repositories and published then in the main repositories as non-snapshots (i.e. http://repo1.maven.org/maven2/org/apache/openjpa/openjpa/1.1.0) I'm having a problem with it in that the pom in openjpa/1.1.0 appears to

Hi Valentin, Did you enhance your entity class NavPoint before executing your query? --- On Thu, 5/29/08, Valentin BUERGEL <[EMAIL PROTECTED]> wrote: > From: Valentin BUERGEL <[EMAIL PROTECTED]> > Subject: ArgumentException > To: users@openjpa.apache.org > Date: Thursday, May 29, 2008, 6:54 AM

Re: JPA: adding entities to EntityManagerFactory programmatically

Hi, again, your documentation is good, and your support as well. It's just me too dumb to read it. Sorry for bothering you, this I could've found out myself. But now for something completely different (hopefully not again a not-read-documentation-issue;) I get the stack trace below when co

Re: JPA: adding entities to EntityManagerFactory programmatically

Hi, To narrow the problem, I will suggest to suppress/remove IProject to see if that changes anything. Are the following statements true for your environment? 1. the persistent classes are not specified at tag of persistence.xml but specified as Map before construction of EMF. 2. The persisten
