I'm trying to generate the metamodel definitions in Eclipse as documented on:
http://www.datanucleus.org/products/accessplatform/jpa/jpql_criteria.html
My project compiler level is set to 1.6 and the mentioned datanucleus jars are added to the factory path.
When the project builds I get the following error:
Errors occurred during the build.
Errors running builder 'Java Builder' on project 'X'.
Could not initialize class org.datanucleus.jpa.query.JPACriteriaProcessor
When using mvn compile the metamodel definitions are generated successfully, so it's probably related to Eclipse annnotation processing.
I'm using latest Spring Tool Suite 3.1.0.RELEASE based on Eclipse 4.2.1
Not put persistence-api.jar (or equivalent, such as Geronimo specs JPA2) in the Factory Path? Either way one of the deps is missing

When I run the sample Drools project in Eclipse, it throws an Exception "The Eclipse JDT Core jar is not in the classpath". I have created the Drools 6 runtime manually. Am I missing something?
Full stacktrace

You are missing the Ecliose jdt core jar. Add yhat jar and it should work.
Added the org.eclipse.jdt.core-3.7.1.jar file to the buildpath of the project and it works perfectly fine. Not sure why this was not part of the Drools runtime which i created manually.
Created a Maven Project and have set the dependencies in the pom.xml. The import statement (com.splunk.*) seems to recognize the library included in the Maven Dependencies, however when I refer to the class (for e.g. ResultsReaderXml) within that library, it shows the "error message cannot be resolved to type". Can some please explain why Spring Tool Suite (Eclipse) is doing that?

Are you using Eclipse Luna for Java Developers (as opposed to Eclipse Classic) AND Scala IDE 4.0 milestone 3? There is a known issue (solved in the nightly builds since then), reported on the mailing list here.
You can "fix" it by either upgrading the Scala plugin to a nightly build (they're pretty stable), or going with Eclipse Classic instead.
Using GGTS 3.6.0M1 with Grails 2.4, I have a java class file that needs an external jar to compile. That jar is defined in BuildConfig.groovy in the "compile" stage, but Eclipse still complains that the references class is not found (because it's not in the Java Build Path).
Since dependency management is performed by Grails, what's the best way to handle dependencies from Java classes that are within Grails projects?
EDIT: Refresh-dependencies doesn't solve the problem of my JAVA classes (under src/java) not seeing the jars in their classpath within Eclipse (showing project errors). If I compile externally - it works (grails compile).
I am trying to upgrade an old project from Spring 2.5.6 to Spring 3.1.0. The project is not built with Maven so I had to add the jars manually to the build path.
The application uses Eclipse RAP as well as Spring.
I added all the Spring 3.1 jars in my build path:
lib/org.springframework.aop-3.1.0.RELEASE.jar
lib/org.springframework.asm-3.1.0.RELEASE.jar
lib/org.springframework.aspects-3.1.0.RELEASE.jar
lib/org.springframework.beans-3.1.0.RELEASE.jar
lib/org.springframework.context-3.1.0.RELEASE.jar
lib/org.springframework.context.support-3.1.0.RELEASE.jar
lib/org.springframework.core-3.1.0.RELEASE.jar
lib/org.springframework.expression-3.1.0.RELEASE.jar
lib/org.springframework.instrument-3.1.0.RELEASE.jar
lib/org.springframework.instrument.tomcat-3.1.0.RELEASE.jar
lib/org.springframework.jdbc-3.1.0.RELEASE.jar
lib/org.springframework.jms-3.1.0.RELEASE.jar
lib/org.springframework.orm-3.1.0.RELEASE.jar
lib/org.springframework.oxm-3.1.0.RELEASE.jar
lib/org.springframework.test-3.1.0.RELEASE.jar
lib/org.springframework.transaction-3.1.0.RELEASE.jar
lib/org.springframework.web-3.1.0.RELEASE.jar
lib/org.springframework.web.portlet-3.1.0.RELEASE.jar
lib/org.springframework.web.servlet-3.1.0.RELEASE.jar
lib/org.springframework.web.struts-3.1.0.RELEASE.jar
and I also listed them in the MANIFEST.MF.
The project builds fine, but at runtime when trying to login it gives me the following error:
java.lang.NoClassDefFoundError: org/springframework/beans/factory/ListableBeanFactory
I looked in the beans jar and the class is definitely there. I also searched through the project and the class is not used explicitly anywhere.
What could cause this? Thank you in advance.
This class does not exist in Spring 3.1.0. See http://www.jarfinder.com/index.php/java/info/org.springframework.beans.factory.ListableBeanFactory
