[jira] Created: (OPENJPA-318) Auto-enhancement within a Web Application

Auto-enhancement within a Web Application
-----------------------------------------

                 Key: OPENJPA-318
                 URL: https://issues.apache.org/jira/browse/OPENJPA-318
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc, jpa, sql
    Affects Versions: 0.9.7
         Environment: Java JRE 1.5
OpenJPA 0.9.7
IDE Eclipse
Tomcat 5.0
MySQL 4.1.9 DataBase (EasyPhp 1.8.0.1)
            Reporter: Frederic Jeanneau


Hello.
I'm still french, so excuse my english one more time.

I have a problem while trying to persist a very simple object, within a web application.
With a web form I create an object, and then the web app try to persist it.

I have just a message with a number and a text.
My Message class is :

@Entity
@Inheritance (strategy = InheritanceType.TABLE_PER_CLASS)
@Table(name = "MESG")
@Id
@Column(name = "NUM_MESG", nullable = false, length = 10)
@Basic
@Column(name = "TXT_MESG", nullable = false, length = 60)

The table is created, but when I send an object to the EntityManager, it fails, because :

Attempt to cast instance "2 [mesobjets.Message]" to PersistenceCapable failed.  Ensure that it has been enhanced.


I tried to launch the server whith -the javaagent argument, but the launching fail, because :

java.lang.reflect.InvocationTargetException
	at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
	at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

	at org.apache.openjpa.enhance.PCEnhancerAgent.premain(PCEnhancerAgent.java:47)
	... 5 more
FATAL ERROR in native method: processing of -javaagent failed


So, if someone know how to auto-enhance on a server, I'm waiting for their ideas, and i'm still trying to solve the problem. Thanks for your help

Hello.
I'm still french, so excuse my english one more time.

I have a problem while trying to persist a very simple object, within a web application.
With a web form I create an object, and then the web app try to persist it.

The EntityManager is loaded for the first object I have to persist, not at the loading of the server, but only when I first try to persist an object. (For the other objects, the EntityManager will be loaded yet).

I have just a message with a number and a text.
My Message class is :

The table is created, but when I send an object to the EntityManager, it fails, because :

[jira] Updated: (OPENJPA-318) Auto-enhancement within a Web Application
