Maven + EclipseLink + Static Weaving

Question

Hi all,
as seen on HCP help, static weaving must be enabled for SDK 2.x in order to fully leverage EclipseLink persistence service.
Since I am using maven, I added the following element to my pom.xml
<plugin>
  <artifactId>maven-antrun-plugin</artifactId>
  <executions>
  <execution>
  <phase>process-classes</phase>
  <configuration>
  <tasks>
  <java classname="org.eclipse.persistence.tools.weaving.jpa.StaticWeave"
  classpathref="maven.runtime.classpath" fork="true">
  <arg
  line="-loglevel FINE -persistenceinfo ./src/main/resources target/classes target/classes" />
  </java>
  </tasks>
  </configuration>
  <goals>
  <goal>run</goal>
  </goals>
  </execution>
  </executions>
  </plugin>
The build completes ok, but at runtime I get any kind of fatal errors:
Exception [EclipseLink-7042] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.ValidationException|
Exception Description: Database platform class [com.sap.persistence.platform.database.HDBPlatform] not found.|nternal Exception:
java.lang.ClassCastException: com.sap.persistence.platform.database.HDBPlatform cannot be cast to org.eclipse.persistence.internal.databaseaccess.Platform|
at org.eclipse.persistence.exceptions.ValidationException.platformClassNotFound(ValidationException.java:1549)|
Is there any major step I'm missing?
Thanks, regards
Vincenzo

Answer 1

Hi Vincenzo,
actually I don't believe that the issue is related at all to static weaving. I'd rather assume that the exception is caused by the combination of EclipseLink 2.5 with the old, proprietary HDBPlatform.
EclipseLink 2.5 has built-in support for HANA and recognizes the database without the need for you to specify the platform explicitly in the persistence.xml file. In fact, EclipseLink 2.5 uses a different platform class (the HANAPlatform class that comes with the eclipselink.jar), so please remove the property "eclipselink.target-database" from the persistence.xml.
Hope that helps.
Best regards,
Sabine
