Re: [eclipselink-users] Lazy Fetch and weblogic issue

Hi Tom,

These are the results of my findings.

When I run the static weaver, I do see methods showing that the weaving was successful along with of course, the _persistence_setaddress_vh method. When I look at the output of the log after static weaving, I do see logging messages showing weaving has occurred for the two classes that I am having issues with:

Note that when I do use the static weaving, the application works fine and the pages does render.

However, when I go back deploying the WAR without the static weaving and set the 2 debug flags for eclipselink weaving as system properties, I only see the presence of one log file pertaining to the org.apache.olio.webapp.model.Address.class. The log itself is hard to read since it contains lots of special characters - not sure why that happens (using vi on a SunFire T200 system) That makes it hard to compare to the static weaving logs but I don't log files for the other classes like SocialEvent nor Person, only for Address. I'm attaching it so you can take a look to see if you can glean something from that log file.

Thanks for any help,

Kim



Hi Kim,

  Is Address an Entity.  (or is it an interface or something else)

Other than that, nothing jumps out at me as a potential cause for the issue.

  Here are some things you can do to try to debug.

1. Run the static weaver and ensure the classes get weaved. You can even use a decompiler to ensure the _persistence_setaddress_vh method exists in the weaved classes.

http://wiki.eclipse.org/Using_EclipseLink_JPA_Extensions_%28ELUG%29#How_to_Configure_Static_Weaving_for_JPA_Entities

2. Set the logging level to FINEST with the persistence unit property eclipselink.logging.level=FINEST

3. Ensure you see a logging message that indicates weaving is starting and one that indicates weaving is ending for the two classes you are having issues with and that there are no errors logged between them. The messages will look like this:

"Begin weaver class transformer processing class [classname]"
"End weaver class transformer processing class  [classname]"

4. EclipseLink has two debug flags that can be used for weaving. Set them an examine the resulting classes. Compare them to the results of static weaving. The following two flags should be set as system properties (not persistence unit properties)

- eclipselink.weaving.output.path=<path>
- eclipselink.weaving.overwrite.existing=true
