I am developing a program with JBoss2.4.4_Tomcat3.2.3 + postgresql7.1.3, and I find a problem. When I update or insert data to database, the database can not be modified, but I can get data from database with select clause at the same time. I use a datasource configurated in jboss. (java:/ds)
I am confused, who can explain the problem to me? Thank you for your help.
More info, please
