Comments on: Migrating from JBoss to Glassfish http://blog.evolutionarydawn.com/2008/03/21/migrating-from-jboss-to-glassfish/ I would love to change the world, but they won't give me the source code Wed, 10 Mar 2010 03:17:20 +0000 http://wordpress.org/?v=2.3.1 By: admin http://blog.evolutionarydawn.com/2008/03/21/migrating-from-jboss-to-glassfish/#comment-8 admin Tue, 25 Mar 2008 14:41:52 +0000 http://blog.evolutionarydawn.com/2008/03/21/migrating-from-jboss-to-glassfish/#comment-8 Thanks Wouter for the post, The comment I made about override must be taken in context of it being un-tested. Meaning that I am blaming my issue on not having equals(Object) @Override but have not verified that it is actually causing my issue. What I do know, is that I have a work around. But now that you have me on my "Soap Box". Generally overriding equals(Object) and hashcode() methods are my biggest annoyance with J2EE spec. Not all "Entities" can have business keys that make them equal because certain business rules prevent it even if all the data attributes are equal. Since I am a bit of a neanderthal this whole idea of overriding those methods has never made sense. Please some write me a comment on how to do this properly so I myself can move on from the stone age. Thanks Wouter for the post,

Using NetBeans to develop JEE applications, Entities are generated by default with the equals method overridden. This is of little use when migrating an existing project from JBoss to GlassFish, but for new projects that are developed for GlassFish this might be a solution. Greets, Wouter Hi David,

If I have time I will contribute it to the Wiki but it might be a month or 2 since I am up againest a deadline. On Issue #3 In JBoss you would not have to em.refresh(object). It appears that there is no caching used on JBoss by default. On em.find(class,object) would actually pull the data from the DB. Sekhar,

These would be great additions to the GlassFish migration guide http://wiki.glassfish.java.net/Wiki.jsp?page=M2GMigrationGuide . The guide is intended to help people with migrating to GlassFish ( see announcement http://forums.java.net/jive/thread.jspa?messageID=261465 ). So,I created links to the three issues in this blog from the migration guide. It would be very helpful if you could contribute your code example/text inline in the migration guide. It is in community based wiki format. So you can edit yourself. If you have any questions, please email at sekhar@dev.java.net. Thanks ! Also, on issue 3, what is being done differently on JBoss ?
