Re: Troubleshooting help

Craig- It sounds like we are initializing an int field, but we are reading null from the database. Can you check the database to see if there are any nulls in the column to which the "id" field is being mapped? Also, if you change the field type from "int" to "Integer", do you get the s

Re: Deadlock when insert in t1 and find in t2

Vlad- Interesting ... looks like it has something to do with an interaction between the JVM and the PCClassFileTransformer agent (responsible for enhancing the entity classes at runtime). If you manually enhance your entities and then run without the -javaagent flag, do you ever get the d

Re: Deadlock when insert in t1 and find in t2

The IBM JVM 5 has "J9" in its name - I couldn't find one that doesn't have it. I tried the same code with Sun's JVM 1.5 (Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)) and I don't get the deadlock. Unfortunately, this doesn't help me because I have to use IBM JVM. -- Be

Yeah, it looks like the attachments were removed by the list server. I'm using Derby. Here are the stack traces for the two threads involved in the deadlock: 3XMTHREADINFO "main" (TID:0x0015EC00, sys_thread_t:0x00358470, state:B, native ID:0x17B4) prio=5 4XESTACKTRACE at co

Re: Deadlock when insert in t1 and find in t2

Vlad- I didn't get any attachments in that last message (perhaps they were stripped by the list server). It might be interesting the see the java stack trace parts of the JVM dump, in case that might shed light on the situation. Also, what database are you using? It could be that the dead

Thanks Michael, Kevin, I think I am making some progress on the Maven plugin. If possible, having one of you guys around on IRC would be a big help for quick questions (I promise to keep them limited) ;-) Thanks again, Rahul - Original Message - From: "Kevin Sutter" <[EMAIL PROTECTE

Re: Should UserTransaction Work?

Don, Glad to hear that you got this working. Since it sounds like you are using application-managed EntityManagers, then you should have two choices to get your PersistenceContext associated with your BMT. As you have found out, you can start the BMT before creating the EM. This is the easiest,

Hi Vlad, Can you provide a bit more information? Are you running in a managed environment or a standalone environment? Are these JTA transactions or Local transactions? What does your test program look like? What about the Entities? Maybe you can attach them to your next reply? I see that yo

Re: Missing ProductDerivation resource error

Rahul, You are referencing old documentation. Please use the following links for the current OpenJPA documentation. Thank you. http://cwiki.apache.org/confluence/display/openjpa/OpenJPA+Documentation Mike has answered the specific question about "jdo" support in OpenJPA in the previous reply.

Deadlock when insert in t1 and find in t2

I have a simple test program that uses OpenJPA 0.9.6 to insert an object into a db in one transaction (t1) and retrieve it in another transaction (t2). The program hangs in 30-50% of the executions right before the call to entitymanager.find() (used to retrieve the object in t2). By looking a

Hi, I've just tried your fix after compiling the OpenJPA trunk. I'm getting a ClassCastException as the openjpa.ConnectionDriverName is set as a StringValue. Should I use another property instead? My code: propMap.put("openjpa.jdbc.DBDictionary", " org.apache.openjpa.jdbc.sql.DerbyDictio

Re: Missing ProductDerivation resource error

Unfortunately you can't use JDO with OpenJPA, so you'll have to convert your jdo mappings files to persistence.xml. OpenJPA and BEA's Kodo share much of the same code, with one of the differences being that Kodo supports JDO as well as JPA. The references to JDO in the OpenJPA documentation were

Re: Missing ProductDerivation resource error

Thanks Michael, I figured that last night after some digging around :-) BTW, when I tried switching the 'openjpa.MetaDataFactory' to 'jdo' in 'openjpa.xml' properties, I got a ClassNotFoundException for 'jdo'. I think the docs online say that 'jdo' is default meta data factory: http://people.

Re: Missing ProductDerivation resource error

Hi Rahul, The problem here is that the enhancer can't find persistence.xml in the classpath. If you have persistence.xml defined in E:\continuum-key-based-refactor\continuum-model\target\classes\META-INF, it should be picked up. Alternatively you can pass in the location of persistence.xml in wi
