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

In order to have syntax color in VIm under CygWin, in your $HOME folder, add a file .vimrc, with this simple line as content:

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.

Use the command:

maven test:single -Dtestcase=com.mypath.(...).MyUnitTest

Use following commands:

• to shutdow: shutdown -s -t 0 -f
• to reboot: shutdown -r -t 0 -f

Here is a very useful way to retrieve UNIX’customs in DOS: creating aliases. For instance, you can type this:

doskey ls=dir

ImageZoom is one of my prefered extentions to FireFox. Yet, sometimes I encounter a situation in which all pictures size is increased.

It is very easy to fix this: in the address bar, launch about:config.

Then find the property imagezoom.defaultGlobalZoom, set it at 100.

And it’s over!
