Re: [eclipselink-users] Does OSGI work?
|
Below is the error when i try to run the examples.
Am I doing something wrong?
Would like to know if anyone has gotten them to work?
This is why I was asking if the OSGi stuff works since I get the same
exception regardless of OS and/or JDK.
1. Get the OSGi bundles and set up Eclipse.
A. Download the EclipseLink 1.0 OSGi Bundles Zip and unpack.
B. Start up Eclipse and File>Import>Plug-ins and Fragments:
C. Uncheck "The target platform (as specified in Preferences)".
D. Hit the "Browse..." button
E. Select the 'plugins' folder of the EclipseLink 1.0 OSGi Bundle.
F. Click "Next".
G. Click "Add All -->" button.
H. Click "Finish" button.
2. Get the source for the demo projects.
A. Get your favorite SVN client.
B. Connect to the Technology SVN (how to:
http://wiki.eclipse.org/SVN_Howto )
C. Checkout all the projects in
[repo_location]/org.eclipse.persistence/branches/osgi/trunk/demos
3. Install Apache Derby
A. Get the 'derby_core_plugin' from
http://db.apache.org/derby/integrate/derby_plugin.html
B. Install it in your eclipse/plugins folder and restart Eclipse
C. Replace the dependency for "org.apache.derby" with
"org.apache.derby.core" in every MANIFEST.MF with
an error.
D. Download the binary version of Derby and run it. (You could get
the UI Derby plugin and then run it)
4. Correct the compile errors:
A. Add a dependency for "javax.persistence" in every project with
the following error "The import javax.persistence cannot be resolved"
B. Add a dependency for "javax.persistence" in every project with
the following error "The type javax.persistence.EntityManagerFactory
cannot be resolved. It is indirectly referenced from required .class
file"
C. Replace the line:
'import org.eclipse.persistence.jpa.config.PersistenceUnitProperties;'
with:
'import org.eclipse.persistence.config.PersistenceUnitProperties;'
in every project with the following error: "The import
org.eclipse.persistence.jpa.config cannot be resolved"
D. THE FOLLOWING CHANGES COMPILE BUT DON'T WORK?!?:
Remove the the third parameter in the method call for
createEntityManagerFactory() for the error:
"The method createEntityManagerFactory(String, Map,
ClassLoader) from the type PersistenceProvider is not visible"
