TomEE: pros/cons of adding openejb-javaagent.jar to java options
What are the pros/cons of adding the following to java options when running
app in/on TomEE via (Windows) service?
-javaagent:C:\apache-tomee-plus-1.6.0-SNAPSHOT\lib\openejb-javaagent.jar
I recognized that NetBeans adds this automatically to java options, when I
start TomEE via netBeans. I recognized this while trying to get the
Sampler>Memory button enabled in Java Visual VM for TomEE running as
Windows service on production server[1].
So, I added openejb-javaagent.jar to java options, and that did not solve
the problem (and after some research, sampler>memory button will be
enabled, if tomee-running-as-service and java visual vm...are the same
'user'...that's my assumption, at least).
So, back to the question, what are the pros/cons of adding
openejb-javaagent.jar to java options of tomee-running-as-service?
Thanks,
Howard

basically openjpa jar is only used when using openjpa as provider so can be
surely removed (with some of its deps)

Posted by "Howard W. Smith, Jr." <sm...@gmail.com>.
The only OpenJPA JAR I could find was openjpa-asm-shaded-2.2.0.jar.
1. I deleted that file from tomee/lib
2. started TomEE, saw no warning, errors, or class not found exception at
startup in the log file
3. ran my web app, saw no issues
4. my app has @Schedule, which invoked silently (only errors show up in the
log); saw no issues
5. i used JMS/ActiveMQ to do some asynchronous tasks (after logging into
web app), saw no issues

Re: TomEE: pros/cons of adding openejb-javaagent.jar to java options
Posted by "Howard W. Smith, Jr." <sm...@gmail.com>.
If for OpenJPA only, why is tomee giving the warning on startup? I only use
eclipselink, and tomee.xml only has my derby JTA resource.
Is OpenJPA used internally by tomee at runtime for other services/etc?
Is the warning there because, OpenJPA is in my tomee/lib? If I delete
OpenJPA from tomee/lib, would that break tomee, because tomee is dependent
on OpenJPA even though I have no tomee resource that need it?
I'm using tomee simple MDB example in my app, so i have no special ActiveMQ
config specified. Is OpenJPA a dependency for tomee simple MDB example?
I have @schedule in my app and multiple singleton beans. Does quartz timer
have OpenJPA as a dependency?

I added the following as java option,
-javaagent:D:\apache-tomee-plus-1.6.0-SNAPSHOT\lib\openejb-javaagent.jar
and the WARNING is no longer in the catalina/tomcat7-stderr log.

Re: TomEE: pros/cons of adding openejb-javaagent.jar to java options
Posted by "Howard W. Smith, Jr." <sm...@gmail.com>.
Well, I was just looking at the server log on production server. Please
note/remember that I am using TomEE 1.6.0 snapshot (2013-04-29). The
WARNING below makes me think that I should add the javaagent to my memory
options. Please advise.
May 04, 2013 8:05:35 AM
org.apache.openejb.assembler.classic.Assembler$PersistenceClassLoaderHandlerImpl
addTransformer
WARNING: JAVA AGENT NOT INSTALLED. The JPA Persistence Provider requested
installation of a ClassFileTransformer which requires a JavaAgent. See
http://openejb.apache.org/3.0/javaagent.html
Below are the lines that followed t he above lines in server/catalina log.
As you see below, i'm using EclipseLink as my JPA provider.
May 04, 2013 8:05:35 AM
org.apache.openejb.assembler.classic.ReloadableEntityManagerFactory
createDelegate
INFO: PersistenceUnit(name=mcmsPU,
provider=org.eclipse.persistence.jpa.PersistenceProvider) - provider time
653ms
I guess I should add javaagent to my tomee java options. Right?

interesting. okay, well, you and I discussed something similar (months
ago), and at that time you advised that I can/should consider weaving my
jpa entities for better performance, but honestly, i never did that, and
therefore, at the moment, i really have no need for this being added to my
java options. :)
as always, thanks Romain!
