Re: [eclipselink-users] Dynamic Weaving question
|
Hello
I tried dynamic weaving, starting tomcat with
-javagent:...../eclipselink.jar
and added <property name="eclipselink.weaving" value="true" /> to the
persistence.xml file
But I get the following error:
Caused by: java.lang.NoClassDefFoundError: Could not initialize class
*********.model.Characteristic

What is causing the error?
When I set eclipselink.weaving to false, everything works fine.

Hello
In the documenation I read: "If the number of classes to weave is
large or the time required to weave the classes is long, consider
using static weaving."
But what is considered a large number of classes (10??,100??).
And how do I know if the time required to weave the classes is long?
And do I have to start Tomcat with -javaagent:eclipselink-agent.jar to
enable dynamic weaving?
Leon
