Fix: In the classpath, replace Weblogic 8.X jars with Weblogic 9.2 jars

Error:

Fix: add a dependency to cglib-full-2.0.2.jar before the other dependencies.

Error:

javax.ejb.EJBException: EJB Exception: : org.hibernate.id.IdentifierGenerationException: ids for this class must be manually assigned before calling save():

Fix: You must assign the primary-key (which is probably a composite-id) before saving the object.

Still another dumb error:

java.lang.NullPointerException at org.dbunit.dataset.DefaultTableIterator.next(DefaultTableIterator.java:59)  at org.dbunit.dataset.AbstractDataSet.getTable(AbstractDataSet.java:77)  at org.dbunit.dataset.AbstractDataSet.getTableMetaData(AbstractDataSet.java:70)  at org.dbunit.dataset.filter.SequenceTableFilter.getTableNames(SequenceTableFilter.java:94)  at org.dbunit.dataset.filter.SequenceTableFilter.iterator(SequenceTableFilter.java:110)  at org.dbunit.dataset.FilteredDataSet.createIterator(FilteredDataSet.java:74)  at org.dbunit.dataset.AbstractDataSet.iterator(AbstractDataSet.java:112)  at org.dbunit.operation.DeleteAllOperation.execute(DeleteAllOperation.java:81)

I’m laughing because I had only to check the DBUnit XML file did start with <dataset> tag… :-S

Here is the stacktrace I have had this morning:

 javax.xml.stream.FactoryConfigurationError: Provider com.bea.xml.stream.MXParserFactory not found   at javax.xml.stream.FactoryFinder.newInstance(FactoryFinder.java:72)   at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:176)   at javax.xml.stream.FactoryFinder.find(FactoryFinder.java:92)   at javax.xml.stream.XMLInputFactory.newInstance(XMLInputFactory.java:136)

To solve it, I had to add following jars to my lib/ folder:

• wls-stax-1.0.jar
• wls-jsr173-1.0-ri.jar

Here is the stacktrace that happened this morning:

Unable to validate using XSD: Your JAXP provider org.apache.crimson.jaxp.DocumentBuilderFactoryImpl@e6a73d does not support XML Schema. Are you running on Java 1.4 or below with Apache Crimson? Upgrade to Apache Xerces (or Java 1.5) for full XSD support.

To solve it, I had to remove the j2ee-X.X.jar from my project.xml Maven config file.

Advice: with Java 5, do not use autoboxing without generics!

Case: you have a jar foo.jar, and you need list the names of the files in it.

Solution: use the following command:
jar -tf foo.jar
