Client's transaction aborted

By tvik
I've met the above error message using a Wicket 1.2 / EJB3 intranet application under Glassfish v2 . Here is the more particular head of the stack trace: javax.ejb.TransactionRolledbackLocalException: Client's transaction aborted at com.sun.ejb.containers.BaseContainer.useClientTx(BaseContainer.java:3394) at com.sun.ejb.containers.BaseContainer.preInvokeTx(BaseContainer.java:3274) at com.sun.ejb.containers.BaseContainer.preInvoke(BaseContainer.java:1244) at com.sun.ejb.containers.EJBLocalObjectInvocationHandler.invoke(EJBLocalObjectInvocationHandler.java:195) at com.sun.ejb.containers.EJBLocalObjectInvocationHandlerDelegate.invoke(EJBLocalObjectInvocationHandlerDelegate.java:127) This exception raised on the integration server sometimes, randomly, for simple page fetch operations. After pressing reload on the browser, the operation was usually successful. I couldn't reproduce the failure on the local machine where I regularly restart the app server and

jxl.log

By tvik
In an intranet production environment we have running a Glassfish v2 appserver with several J2EE applications which all use JexcelApi , a.k.a JXL, which is an open source library for accessing, generating or manipulating Microsoft Excel documents. We use version 2.6.3 of JXL because it's the recent one in the Maven repository which we use, however, at the official JXL site there are newer versions. Additionally we have log4j and Java Commons Logging (JCL), ignoring Glassfish's JSR-47 Java Util Logging (JUL) facility. Application #1 uses purely log4j and gets its log4j.xml config from a custom location. Application #2 runs Java Commons Logging with no explicite configuration file given, so JCL uses the default JUL facility of the appserver. Application #1 had been running for a long time without problems but when we installed #2 we realized that a jxl.log file had been created in the glassfish/domain/domain1/config directory and it's rapidly growing. As it happens, we

Brillien

By tvik
There were three presentation as usual at the 14th Java User Meeting at Budapest yesterday, but this time I'll write only about the first one. Imre Fazekas had been invited from Debrecen to make a presentation about Brillien , their Java enterprise platform. It's an alternative way of modeling and implementing business logic in place of Java Enterprise (J2EE) Technology. It uses invasive programming model which means we have to extend classes from Brillien superclasses and we may use annotations. The whole system based on asynchronous XMPP communication and a set-context-flow concept. It's something like an application server, but uses a more logical and set-based approach. As the presenter said, it has very good speed and performance characteristics. Currently there are no IDE or other tools for editing models because this is a very young project, however a Maven plugin and a Maven archetype is accessible on the homepage. A very good introduction and tutorial can be also
