EJB3 releases a plugin every 2nd and 4th Friday of the month, so i plan to get this into the next plugin release in a couple of weeks.

[JBoss XML Binding Development] - XB profiling during the AS start-up

by alex.loubyansky＠jboss.com

To get an idea of what's taking time in XB during the AS start-up, I added simple time checks for three things: - creation of unmarshaller instances (parsers) - unmarshalling (parsing xml + assembling the Java graph) - schema binding (parsing of JBossXB/JAXB annotations) I started the default AS configuration 10 times and here are the average time results. AS start-up: 26385 ms XB total: 2460 ms or ~9% of AS start-up unmarshallers (95 instances): 90 ms or ~4% of XB total unmarshalling (72 files): 1331 ms or ~54% of XB total binding (17 schemas): 912 ms or ~37% of XB total First thing I tried was schema binding creation by means of serialization/deserialization of schema bindings instead of re-building them on every start-up from Java annotations (that was a long awaiting feature request). Deserialization of schema bindings (with the standard Java serialization) appears to be around 6.5 times slower then building schema bindings from annotations. Classloading during deserialization takes around 140ms which is ~3% of total derserialization time. So, the idea of serializing/deserializing schema bindings with standard Java serialization is not looking good. Then I looked into reading annotations (class-, property-, package-level) during schema binding construction. For all the schemas during AS start-up the total average time is 127 ms which is ~14% of the binding time and ~5% of the XB total time. So, this looks good and looking for another source to get this information from doesn't make sense. What's left for the optimization of schema binding creation is the way the data from annotations is processed. The total average time to process the data from annotations is 785 ms, which is ~86% of total binding time and ~32% of total XB time. So, at the end the main areas for optimizations in XB during AS start-up are: - unmarshalling (xml parsing + assembling the Java graph) which takes 1331 ms or ~54% of the XB total time - processing annotation data during schema binding creation which takes 785 ms or ~32% of the XB total time But before I proceed with the annotation processing optimization I'm gonna get some more details for the unmarshalling time, i.e. pure XML parsing (which is xerces) vs the rest of the XB unmarshalling code.

[JBoss OSGi Development] - Re: Autostart bundles when deployed in JBossAS

by thomas.diesler＠jboss.com

[JBoss Microcontainer Development] - Re: m2eclipse or not

by thomas.diesler＠jboss.com

It changes the eclipse .classpath file to read | <classpath> | <classpathentry kind="src" output="target/classes" path="src/main/java"/> | <classpathentry kind="src" output="target/tests-classes" path="src/test/java"/> | <classpathentry excluding="**" kind="src" output="target/tests-classes" path="src/test/resources"/> | <classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/J2SE-1.5"/> | <classpathentry kind="con" path="org.maven.ide.eclipse.MAVEN2_CLASSPATH_CONTAINER"/> | <classpathentry kind="output" path="target/classes"/> | </classpath> | Basically m2eclipse reads the pom to maintain a dynamic classpath container. If dependencies (also transitive) in the pom change that gets reflected automatically in the eclipse classpath. I am asking because I see stale classpath definitions, which would not occur if m2eclipse was used. The down-side (if there is one) would be that folks have to install the m2eclipse plugin. In short: It doesn't affect you at all ;-) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4255546#4255546 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4255546

The reason we removed before/afterdelivery is because we shouldn't need to call it as we are starting the tx before the delivery.
