Re: [JBoss-user] clustering question
I know this is OT, but the thread reminded me of this... Has anyone looked at using something like "JSR-107: JCACHE - Java Temporary Caching API" to help in keeping cached entity beans in a cluster synchronized instead of relying solely on the database?

Re: [JBoss-user] GMS address
Remove cluster-service.xml from your deploy directory or enable multicasting on your box.

I seem to recall someone mentioning that hypersql allows two columns in a table to have the same name. This is not normally allowed in SQL databases, right? If your test case only tests against hypersql, then it will probably give a false positive result. I filed bug 530437 (http://sourceforge.net/tracker/?func=detail&aid=530437&group_id=22866&atid=376685) because I ran into a similar problem using postgresql which complains about the relationship table that has two columns with the same name. Now in my case it is a many-to-many self-relationship, but a one-to-many self-relationship also needs to have a separate relationship table, right? --Andrew ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
Re: [JBoss-user] CMP in EJB2.0 with Postgres
This is probably not the best way to do this, though, since hypersql's setup is different from a standard JDBC driver. (The database runs in the same VM as JBoss) A better solution is get the 3.0 postgresql-service.xml from the public documentation on the database setup: http://jboss.org/online-manual/HTML/ch03s12.html and modify it for your setup. (Change the server address, username, password, etc.) You can just dump the postgresql.jar file into the deploy directory to make it accessible.

Re: [JBoss-user] JBoss and standalone Tomcat 4.0.2
The problem is that standalone tomcat doesn't know how to contact the JBoss JNDI registry. To do this, you can either put a jndi.properties file in your path (I am not sure where, when using tomcat) or you can manually put the values from a jndi.properties file into a Properties object and pass it to the constructor for the InitialContext class.

Re: [JBoss-user] duplicate columns created
David, I have found and reported a similar problem with an EJB that needs to have a many-to-many relationship with itself. Look at bug#532262: http://sourceforge.net/tracker/?func=detail&aid=532262&group_id=22866&atid=376685 You should probably add your problem to this bug report... (I hadn't realized the duplicate column name situation would occur in other situations as well.) I've spent about 10 minutes looking for (and at) the code that is doing the column name creation, but it will take me more time (than I currently have) to come up with a real fix/patch. I'm willing to spend more time on this if someone more familiar with the code will point me in the right direction as to how to fix this without breaking all kinds of other things.

[JBoss-user] Re: [JBoss-dev] How can JBoss get EJB-classes from other location
This question probably doesn't belong on the jboss-development list... However, here's what I've come to do: Depending on what I am working on most, I tend to use one of two development modes: 1) Work on EJBs with sporadic JSP/Struts work. In this case I find it most convenient to tell my ant build.xml to construct an .ear file containing both the EJB jar and war files and move it to the JBoss deploy directory. 2) Work on JSP/Struts with sporadic EJB work. For this mode, I run Tomcat separately and simply use its management interface to reload to get any new Struts code recognized. (JSPs are compiled automagically already...) Talking with the JBoss hosted EJBs in this mode simply requires setting the JNDI properties. Since #2 above requires more memory since you're running 2 JVMs, it might not be ideal for all development, but there is nothing to stop you from running the two on separate machines. (In my case this is closer what the end product will have to do anyway...) I will also use #2 when I hand over the HTML/JSP GUI to my GUI people. (They have no business manually compiling anything anyway! :-)) If you need more details on any of this, let me know. I am also open to suggestions from others on how to improve the full application development environment and process. storck wrote: >Hi, > >is it possible that JBoss "loads" the classes from my ejbs from another >directory than /deploy?
