At JavaOne 2000 I presented a talk entitied Advanced Tx Processing II (TS988). Although the presentation is available from JavaSoft, the source is not. After the presentation a swarm of people came up asking for the source code. Please find it, as well as deployable EAR and JAR files on the Sybase newsgroups. news://forums.sybase.com/powersoft.public.easerver The posting has the subject of "JavaOne Advanced Tx Processing Presentation Source Code" This is built using EJB 1.1 and should contain (aside from the GUI) no proprietary API's or classes and should be easily ported to 3rd party containers. The application is for a mock bank. It shows a simple interaction between Session Beans and Entity Beans using BMP (For CMP I reccomend CoCoBase from Thought Inc which integrates well with most every app server including EAS). It also allows you to configure the server to do XA distributed transactions. Requirements: An app server (like Sybase EAS 3.6) capable of EJB 1.1 To see XA transactions, an app server (like Sybase EAS) capable of XA an XA JDBC driver, and an XA capable database A database Java2 VM Installation: The EAR and JAR can be deployed as needed in your particular app server. In EAS 3.6 you can use the deploytool or JaguarManager. You will need to set all EJB 1.1 resource ref's to point to the appropriate connection caches. For non-XA you only need to set the primary caches. The CustomerAccountEntity entity bean also has an environment variable called "use_xa" which should be set to false unless you have an XA capable database. To run the client simply make sure that swingall.jar is in the classpath, jndi.jar is in the classpath, and you're containers classes are in the classpath (%JAGUAR%\html\classes for EAS). Then configure the environment.props file as needed. The Goal: This demo was designed to allow developers to experiment with container managed transactions and declarative transactional settings. For instance, a simple example is to transfer money from one account to another user teller id'1'. To show it is successful. If you ever reach a negetive balance, the tx will rollback. If however you try to transfer money as teller id '2' it may or may not fail. If the Log component is set to inherit the running tx (support or requires) then it will rollback as there is a referential integrity constaint on the logging table. However it it is set to say requires new or not supported, it will now roll forward. The demo also shows doing an update via the JTA and an XA transaction for those containers capable. This demo is provided as-is and all support is given via this newsgroup. This is the first bundling of this demo so there may be issues. Please let me know in the newsgroup and Ill fix um! news://forums.sybase.com/powersoft.public.easerver Dave Wolf Internet Applications Division =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff EJB-INTEREST".
