Questions about classpath for OpenJPA
I am just getting started and created a simple standalone (not in an app
server container) JPA application working with both TopLink and OpenJPA
1.2 and tested with both MySQL and Postgres. This is with Java SE
1.5.0_05 building with Ant (not in in an IDE).
By trial and error I found I needed the jar files downloaded in the
apache-openjpa-1.2.0 lib directory. I also needed xercesImpl.jar. I did
not find these dependencies documented in the release notes, or in the
manual, or on the Quickstart page
(http://openjpa.apache.org/quick-start.html).
These were the necessary jars at either compile time or runtime -
commons-collections-3.2.jar
commons-lang-2.1.jar
geronimo-jpa_3.0_spec-1.0.jar
geronimo-jta_1.1_spec-1.1.jar
openjpa-1.2.0.jar
serp-1.13.1.jar
xercesImpl.jar
Probably I will also need commons-pool-1.3.jar or something similar for
Connection pooling.
Presumably the geronimo jars are not needed in a Java 5 EE container.
I'm not sure why xerces is required since Java SE 1.5 has a SAX parser.
I guess all the other jars need to be deployed in the classpath in most
other contexts.
This kind of dependency information might be usefully documented
somewhere. Every new user has to figure this stuff out.
BTW - My target runtime environment will be Tomcat 6 + Java SE 1.6 +
OpenJPA 1.2 + Postgres 8.2.x
Any experience or advice about what jars are required or is this already
documented somewhere?
Thanks - Paul

Cool! That's very nice and it makes sense that starting a new JVM
changes the class loader issue. Notice the ant lib directory includes
xercesImpl.jar (ant 1.7.1). That also explains why the OpenJPA examples
work because the examples build.xml has fork=yes.
Thanks for figuring that out. Might help the next poor developer that
hits this. :-)

Paul -
I don't fully understand whats going on, but I found what is causing the problems. When you launch your java application, you don't fork the JVM. Adding fork="yes" to <java classname="com.s... > made the problems go away.
If you google around, you'll find other people having this very problem.
-Rick
Hi Rick -
What I think is happening is that most containers have the JAXP jar
files, but if you run it standalone from the console this issue shows
up. There was an evolution from java 1.4 to 1.5 that changed how this
works. There are a lot of posts if you google it, but I'm no clear on
the what the configuration trick is so you don't have to have xercesIml.jar.
Attached is is a bare bones zip file. Directions -
- Add the jars from OpenJPA 1.2.1 to the lib directory and your JDBC driver
- Create a database with the test_person table for class
com.steelhead.lg.test.Person
- Edit src/java/META-INF/persistence.xml with your connection properties
- type "ant TestJPA"
This should work. If you remove the two sysproperty elements from the
ant build.xml then it fails with
javax.xml.parsers.FactoryConfigurationError unless you add
xercesImpl.jar to the lib directory.
I'm using Java SE 1.6.0_12. I had the same problem with Java 1.5.0_05.
Also had the same issue with OpenJPA 1.2.0.
I'm using Postgres 8.2.13 but I had the same problem with MySql 1.31 so
probably the database does not matter.
As I said, the OpenJPA hellojpa example works for me without
xercesImpl.jar so that adds to the mystery.

Hi Rick -
What I think is happening is that most containers have the JAXP jar
files, but if you run it standalone from the console this issue shows
up. There was an evolution from java 1.4 to 1.5 that changed how this
works. There are a lot of posts if you google it, but I'm no clear on
the what the configuration trick is so you don't have to have xercesIml.jar.
Attached is is a bare bones zip file. Directions -
- Add the jars from OpenJPA 1.2.1 to the lib directory and your JDBC driver
- Create a database with the test_person table for class
com.steelhead.lg.test.Person
- Edit src/java/META-INF/persistence.xml with your connection properties
- type "ant TestJPA"
This should work. If you remove the two sysproperty elements from the
ant build.xml then it fails with
javax.xml.parsers.FactoryConfigurationError unless you add
xercesImpl.jar to the lib directory.
I'm using Java SE 1.6.0_12. I had the same problem with Java 1.5.0_05.

Hi Rick -
Thanks. As I mentioned the openjpa example hellojpa also works for me
WITHOUT the xerces jar. But my very simple test app does not work with
xerces. However, I found out that if I add these two properties to my
runtime ant task then I do NOT need the xerces jar.
<sysproperty key="javax.xml.parsers.SAXParserFactory"
value="com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl"/>
<sysproperty key="javax.xml.parsers.DocumentBuilderFactory"
value="com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl"/>
There is some classloader subtlety that I don't fully understand here.

I quickly looked through the javadoc for the
http://java.sun.com/javase/6/docs/api/javax/xml/parsers/SAXParserFactory.html#newInstance()
SAXParserFactory and I'm thinking that your problem is something specific
to your environment.? I was able to run the examples on my box without
adding xercesImpl.jar to my classpath. With my JSE1.6 install,
SAXParserFactoryImpl is found in the [java_home]\lib\rt.jar.

Re: Questions about classpath for OpenJPA

More info on this. I upgraded to Java SE 1.6.0_12 and I still need the
same jars (including xerces).
Using OpenJPA 1.2 -
1) Only two jars are needed to compile my (very simple) test application -
- openjpa-1.2.0.jar
- geronimo-jta_1.1_spec-1.1.jar
2) At runtime (standalone, not in a container) I also need these jars (plus JDBC driver of course) -
- serp-1.13.1.jar
- geronimo-jta_1.1_spec-1.1.jar
- commons-collections-3.2.jar
- commons-lang-2.1.jar
- xercesImpl.jar
3) When I build and run the apache-openjpa-1.2.0/examples/hellojpa
(Derby example) I do NOT need xerces.
But this is the exception I get (with both Postgres and Mysql) with my
very simple app without xercesImpl.jar. This occurs on the call to
Persistence.createEntityManagerFactory() -

Re: Questions about classpath for OpenJPA
Posted by Michael Dick <mi...@gmail.com>.
Hi Paul,
Sorry for the confusion. I thought you were building OpenJPA, not building
an OpenJPA application. OpenJPA applications can compile with whatever JDK
they like ( so long as it's >= 1.5).
Regarding xerces, do you know if that dependency is pulled in because of
OpenJPA, or because of commons-dbcp? In the performance related thread I had
to pull xerces and ran into a bug with version 2.0.4 (IIRC might have been
2.4.0). I had to manually move up to 2.9.0 to get past the problem (might
work with earlier versions, I just grabbed the latest from the maven
repository).

Interesting. Does this Jira bug say that OpenJPA applications can
compile and run with Java 1.6 as long as they do not use JDBC 4
methods? Another item for the release notes :-) ...

Re: Questions about classpath for OpenJPA

Hi Paul,
Sadly 1.6 might not be the best move [1]
[1] http://issues.apache.org/jira/browse/OPENJPA-5.
It's been on the back burner for too long. At runtime you'll be fine with
1.6, but we still don't have the JDBC interfaces updated for v4.

I had the older Java 1.5.0_05 already installed and haven't bothered to
update since I plan to go to 1.6. Correct me if there is any reason why
I shouldn't go to 1.6.
My use case here is sort of the minimal case. Others are using an IDE
or deploying on an application server where the dependencies are different.

Re: Questions about classpath for OpenJPA

Hi Paul,
For Tomcat related information, you may be able to derive some information
from this thread [1]. It began as a data source related issue but got into
some configuration issues as well.
I've only used Tomcat 5.5 with OpenJPA. I'm not sure about Tomcat 6, but
5.5 did not come with geronimo spec api jars (or equivalents). Here are the
OpenJPA bundled jars that I needed to copy into the tomcat/common/lib
directory:
- openjpa-1.2.0.jar
- serp-1.13.1.jar
- geronimo-jta_1.1_spec-1.1.jar
- geronimo-jpa_3.0_spec-1.0.jar
- commons-collections-3.2.jar
- commons-lang-2.1.jar
You'll also need to make your JDBC driver jar(s) available to your app(s).
I added them to common/lib. You may also be able to bundle all these jars
in your WAR, but I found it cleaner to make them common libs.
You may choose to use JNDI data sources with Tomcat vs. direct
configuration. Here is a an article for configuring pooled data sources
with Tomcat.[2] Until you make the jump to Tomcat, here is a link for
configuring pooled datasources with OpenJPA in a JSE environment using
dbcp.[3]
JRE 1.5.0_05 is fairly old. I'd try updating to a newer JRE. I'm currently
using 1.5.0_15. Just a guess, but something may be relying on parser
related updates in newer versions of the JRE.

Re: Questions about classpath for OpenJPA

I have no idea why there's a dependency on xercesImpl... First time I have
heard of this.
I agree that our QuickStart needs some work. Volunteers are always
welcome. :-)

Hello Paul.
You may consider to add commons-dbcp and commons-pool jars for
connection pooling. You may use commons-pool for pooling EntityManager
instances.
