RE: Problem with openjpa enhancer - using runtime enhancement
Hi all,
although the issue is a time ago. I would like to take the opportunity
and ask around if anybody has the same feeling about the mentioned
logging issue when dealing with the mappings file (see below)? if I put
the orm.xml file away (or renamed it) and an exception occurrs at the
first query like
<openjpa-1.1.0-r422266:657916 nonfatal user error>
org.apache.openjpa.persistence.ArgumentException: An error occurred
while parsing the query filter "SELECT b FROM ... AS b". Error message:
The name "..." is not a recognized entity or identifier. Known entity
names: []
turning the ll DEBUG on metadata brings
10:21:59,311 DEBUG [MetaData] Scanning resource "orm.xml" for persistent
types.
10:21:59,311 DEBUG [MetaData] Scanning resource "META-INF/orm.xml" for
persistent types.
10:21:59,311 DEBUG [MetaData] parsePersistentTypeNames() found [].
10:21:59,311 DEBUG [MetaData] Found 0 classes with metadata in 16
milliseconds.
... I admit that normally you would check the presence of the orm.xml as
one of the first actions. On the other hand, I found this message
confusing as it is now with 1.1.0, because one can think that the file
("orm.xml") specified in persistence.xml is loaded successfully and the
problems with fining zero instances is somewhere else ... (these
messages shown above appeared, because the file was intentionally named
"orn.xml".)
For us this was confusing, because we have replaced an or-mapper with
openjpa in many projects, so many developers were affected to migrate
their software. and with this situation, with many issues to cover at
the same time, a lost/renamed/wrongly placed mapping file is quite
likely. We have added a warning in the startup of our software if
annotations or mapping file haven't been found, because so many
developers have complained about "where is the problem with that"
situation. So I wondered if others felt similar about the missing
mapping file thing?

Kevin,
This is the trace output from our build with all the OpenJPA options set
to TRACE and RuntimeUnenhancedClasses set to unsupported, it looks like
it finds the classes but fails to enhance any of them. One slightly odd
thing about this is that it mentions that it is scanning the resources
"META-INF/orm.xml" for persistent types but this file doesn't exist, all
the persistent types are listed in the persistence.xml file, I don't
know if this has any significance. I have also put in the test report
from the initial test case that fails.
Thanks
Gareth

Subject: Re: Problem with openjpa enhancer - using runtime enhancement
Gareth,
If you are still falling into the non-enhanced class file path, then
there's still something wrong with the javaagent processing. I'm not
following the reference that Nathan provided [1]. I'm not clear on what
it's trying to tell me. Is the javaagent provided by OpenEJB supposed
to automatically include the one provided by OpenJPA? The jar file that
was referenced previously does not seem to have any OpenJPA code in it,
so I'm confused.
Or, does OpenEJB require both agents? Maybe this needs to be discussed
on the OpenEJB forum? I'll try cross-posting to see if we get any
input.
In the mean time, you could turn on the OpenJPA trace to see if we are
even getting any of the classes to be enhanced. My guess is that this
trace won't show the classes because they are not getting to our agent
for transforming. But, it's worth a shot. Maybe there's some problem
during the transformation that gets eaten by the classloading mechanism.
Another possibility is that the class that gets transformed during the
agent processing is not the same class that is loaded later by the
runtime. A classloader issue with OpenEJB? A long shot, but I'm just
trying to generate some thoughts by any of the readers.
Can you provide more details on the specific messages you are getting
after turning off the fallback enhancement process? Does it show all of
your entities as not being processed? Or, is it a subset? Are you
listing your classes in your persistence.xml or are you relying on
classloader detection?
I have not seen a problem with the agent enhancement process. It's
basically the exact same code as our static enhancement, except for how
it's kicked off. Any additional details or testcases on how to
reproduce it would help with the diagnosis.
Thanks,
Kevin
