Dear persistence gurus,
I ran the persistence example at
https://glassfish.dev.java.net/javaee5/persistence/persistence-example.html
on Java SE using -javaagent and everything worked great
(as shown below):
D:\sw\javapersistence_javase_ex1\classes>java -cp d:\tscextdep\lib\mysql.jar;. -javaagent:d:\glassfish_cvs\publish\glassfish\lib\toplink-essentials-agent.jar client.Client
[TopLink Info]: 2006.01.11 09:30:31.484--ServerSession(15431769)--TopLink, versi
on: Oracle TopLink Essentials - 10g release 4 (10.1.4.0.0) (Build 051205Dev)
[TopLink Info]: 2006.01.11 09:30:32.031--ServerSession(15431769)--pu1 login successful
Inserting Customer and Orders... OK
Verifying that all are inserted... OK
Removing all... OK
Verifying that all are removed... OK

I am now trying to run the same example without the -javaagent.
I talked to Marina, and she mentioned that the option "no.weaving"
should do the trick. The persistence.xml is as follows:
(note that I have tried with both "no.weaving" and "toplink.no.weaving")
<persistence xmlns="
http://java.sun.com/xml/ns/persistence">
<persistence-unit name="pu1">
<provider>oracle.toplink.essentials.ejb.cmp3.EntityManagerFactoryProvider</provider>
<class>entity.Customer</class>
<class>entity.Order</class>
<properties>
<property name="jdbc.driver" value="org.gjt.mm.mysql.Driver"/>
<property name="jdbc.connection.string" value="jdbc:mysql://localhost:3306/test?autoReconnect=true"/>
<property name="jdbc.user" value=""/>
<property name="jdbc.password" value=""/>
<property name="toplink.logging.level" value="INFO"/>
<property name="no.weaving" value="true"/>
</properties>
</persistence-unit>
</persistence>
Unfortunately, I get an NPE as shown below:
D:\sw\javapersistence_javase_ex1\classes>java -cp d:\tscextdep\lib\mysql.jar;.;d:\glassfish_cvs\publish\glassfish\lib\toplink-essentials.jar;d:\glassfish_cvs\publish\glassfish\lib\antlr.jar;d:\glassfish_cvs\publish\glassfish\lib\javaee.jar;d:\glassfish_cvs\publish\glassfish\lib\asm.jar;d:\glassfish_cvs\publish\glassfish\lib\asm-attrs.jar client.Client

Any help to solve this issue would be greatly appreciated.
Thanks!
