Subject May be issue about OpenJPA 2.2.1 or configuration issue, could you help me to solve this issue.
Date Tue, 22 Jan 2013 07:10:10 GMT


Hi all,

   Our project(base on osgi) upgrade openJPA from 2.1.0 to 2.2.1. I follow
the user guide add the property in the persistence.xml as following
<property name="openjpa.Compatibility" value=
"CheckDatabaseForCascadePersistToDetachedEntity=true" />
 but after adding it into the persistence.xml, when we do the enhancement
of the Entity, we run into such kind of error  in red color.
my enhancement script in eclipse:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<launchConfiguration
type="org.eclipse.ui.externaltools.ProgramLaunchConfigurationType">
<listAttribute key="org.eclipse.debug.ui.favoriteGroups">
<listEntry value="org.eclipse.ui.externaltools.launchGroup"/>
</listAttribute>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_LOCATION" value="$
{system_property:java.home}${system_property:file.separator}bin$
{system_property:file.separator}java"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_TOOL_ARGUMENTS"
value="-Djava.ext.dirs=com.ibm.cfs.persistence.jpa$
{system_property:file.separator}lib -cp com.ibm.cfs.persistence.jpa$
{system_property:path.separator}com.ibm.cfs.persistence.jpa$
{system_property:file.separator}target$
{system_property:file.separator}classes$
{system_property:path.separator}com.ibm.cfs.core$
{system_property:file.separator}target$
{system_property:file.separator}classes${system_property:path.separator}
org.apache.openjpa.enhance.PCEnhancer ${build_files} -tcl false"/>
<stringAttribute key="org.eclipse.ui.externaltools.ATTR_WORKING_DIRECTORY"
value="${workspace_loc}"/>
</launchConfiguration>

   Anything we missed?

The plugin property                      
 "CheckDatabaseForCascadePersistToDetachedEntity" had no corresponding setter method or accessible

and I download the source code of openJPA, and there is no method invoke
the method of setCheckDatabaseForCascadePersistToDetachedEntity of
Compatibility class.



Thanks for any help or info for this issue
