Roullier... I Can understand you, but you agree to me that is strange? I don't wanna also get into a protracted discussion here... =) I am Brazilian, then almost all days I am happy...=)
But, the enviroment of my application is: WebServices Which I am using Apache Axis, Then I can to use JBoss with TomCat, And uses DBCP from this guy. But, besides this, I will use DataSource to use CMP's. By this trouble, I am asking you about some special configuration using JBoss DataSources, in transaction-services.xml, or something inside dabase-ds.xml, Do you know? Imagine one Application using a big amount of StoredProcedures, So I could not use EntityBeans, the major possibility is to Use SessionBeans. However , I am worried with this problem. Do You can guarantee me that whether always I close my connections, the Pool will work fine?
