Use this:

javap -c myClass

(do not mention .class)

Error:

MyStrutsAction     - Error on uploading: MyPersonnalClass@971720[primaryId=<null>,type=XXX,myDate=20080702,entityId=<null>,optimisticTimestamp=<null>] org.springframework.remoting.RemoteAccessException: Could not access remote service [my-service-bean]; nested exception is javax.transaction.TransactionRolledbackException: BEA1-0F416BB49A8BE6353E83: javax.transaction.xa.XAException: JDBC driver does not support XA, hence cannot be a participant in two-phase commit. To force this participation, set the GlobalTransactionsProtocol attribute to LoggingLastResource (recommended) or EmulateTwoPhaseCommit for the Data Source = myDatasource

Fix:

• Go on WebLogic console
• Then follow the pages: Home > Summary of JDBC Data Sources > myDatasource > Transactions
• Uncheck:One-Phase Commit
• Check: Emulate Two-Phase Commit

Error

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'jmsQueueConnectionFactory' defined in class path resource MyResourceApplicationContext.xml]: Invocation of init method failed; nested exception is java.lang.NoClassDefFoundError: com/sun/corba/se/connection/ORBSocketFactory

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

Error:

Fix: Upgrade AntLR from version 2.7.2 to 2.7.6

On calling:

MockClassControl.createStrictControl(Toto.class);

Error:

java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.<init>(Z)V

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!
