    Wierd problem mysql w/jboss-tomcat

      I am new to use JBoss, I experienced some wierd problem to config jboss-tomcat with mysql.

      First, my OS is windows XP pro, J2SE sdk is 1.4.1-02

      I downloaded jboss-4.0.0DR1_tomcat-4.1.24.zip from this website. unzip to c:\ rename as jboss-tomcat.

      Tested with simple servlet, jsp, stateless session bean, simple entity bean. All worked great.

      Than I try to integrate mySQL. I downloaded and installed mysql-4.0.13-win.zip(seems fine as its standalone)
      downloaded the connector from this website, copyed mysql-connector-java-3.1.0-alpha-bin.jar to
      c:\jboss-tomcat\server\default\lib

      I deleted hsqldb-ds.xml under
      c:\jboss-tomcat\server\default\deploy

      copyed the mysql-ds.xml from
      c:\jboss-tomcat\docs\examples\jca
      to
      c:\jboss-tomcat\server\default\deploy
      changed MySqlDS to DefaultDS, dell to localhost,
      org.gjt.mm.mysql.Driver to com.mysql.jdbc.Driver


      also, I edited
      C:\jboss-tomcat\server\default\conf\standardjaws.xml
      and
      C:\jboss-tomcat\server\default\conf\standardjbosscmp-jdbc.xml
      to change "Hypersonic SQL" to "mySQL"

      than after restart jboss, all test run fine except the entity bean. The ear seems can not load correctly. I have no idea why, because lack of information, I must make some mistake to modify jboss configuration files.

      because if I roll back the changes done to integrate mySQL, entity bean works fine again.

      Thank you in advance for your help

          Forget to mention, the entity bean seems use CMP.

            SOme other detail about this problem.

            Seems it is because mysql won't load.

                I have the same problem with:

                JBoss3.2.2 + mysql 4.0.16 + mysql-connector-java-3.0.6-stable-bin.jar and JVM 1.4. + WindowsXP pro.

                However, if I installed everything onWindows2000 pro, everything is working just fine. (I've tried it on 3 machines).

                Help please,
                thanks,
