RE: [JBoss-user] CMR uses the default datasource in stead of the one specifically specified for the CMP 2.0 EJB entity beans concerned
Hi, I faced the same problem some time back and this is how I solved it (on JBoss 3.0.6). My application was using data from PostgreSQL database and I had to access use data residing a M$ SQL 2000 database. I had configured the entire application to use PostgreSQL for CMP persistence. I did this by creating a META-INF/jbosscmp-jdbc.xml containing something like this. java:/PostgresDS PostgreSQL 7.2 true false false 300 true true false foreign-key on-load 1000 * 1000 PBudgetSummaryLineItemYearEJB java:/MSSQLDS MS SQLSERVER2000 PBudgetSummaryLineItemYearEJB true Now all the CMP entity beans in my application are using the PostgreSQL datasource. EXCEPT the PBudgetSummaryLineItemYearEJB CMP entity bean which is using MSSQLDS datasource for persistence. Of course the datasources have to be configured in your JBoss installation.

RE: [JBoss-user] CMR uses the default datasource in stead of the one specifically specified for the CMP 2.0 EJB entity beans concerned
I use the normal download (with Tomcat integrated) from the Jboss Site jboss-3.0.6_tomcat-4.1.18. Here is the release log. JBoss Release: JBoss-3.0.6 CVSTag=JBoss_3_0_6 How and where can I get that latewst release?

What JBoss version are you using?
