    MySQL database connection error

    Csaba K Newbie

      Hy all!

       

      I am trying to change H2 database to MySQL database. I installed a MySQL server and went through http://docs.jboss.com/jbpm/v5.4/userguide/ch.installer.html#d0e609 on this description. I started jboss AS7 and MySQL server also, I opened http://localhost:8080/jbpm-console/.

      After I logged in I got this error:

      My questions are:

      Should I create the MySQL DB schema (I thin I should), and if I should where can I find an SQL script for this?

      The first error  also caused by the DB error?

       

      Thanks for your help!

       

      Best Regards,

          My questions are:

          Should I create the MySQL DB schema (I thin I should), and if I should where can I find an SQL script for this?

          The first error  also caused by the DB error?

           

          Thanks for your help!

           

          Best Regards,

          Kedves Csaba!

           

          Az entitás tárolókat (adatbázis táblákat) automatikusan létrehozza a perzisztencia kezelő (lehet rá írni külön telepítő klienst, de az update bőven elegendő)

          persistence.xml:

          <property name="hibernate.hbm2ddl.auto" value="update" />

          .

          A sequences táblát azért keresi, mert egyedi azonosítója van egy entitás osztálynak, de nincs -vagy rossz- generálási stratégiával van ellátva.

           

          Próbáld ki ezt:

          @Entity -> @Id -> @GeneratedValue(strategy=GenerationType.IDENTITY)

          Újraidítás előtt dobd el a táblákat, hogy újra létrehozza ezeket az entitás tárolókat, és beállítsa a primary key mezőt a táblára.

           

          üdv.,

            Thank you for your answer, I tried, but it did not work.

             

            I attached my server.log file, and the files in my jbpm/db directory.

            It seems, that it can not create the connection with the mysql server at all..

            What is missing/wrong?

             

            Thank you!

              Okay, let's speak english. I use JBoss 7.1.1, and my jBPM knowledge is poor. But it seams that jbpm5 doesn't accessible from your datasource.

               

              My sample-ds.xml in a JBoss-tools generated JPA/CDI project:

               

              <datasources xmlns="http://www.jboss.org/ironjacamar/schema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

                  xsi:schemaLocation="http://www.jboss.org/ironjacamar/schema http://docs.jboss.org/ironjacamar/schema/datasources_1_0.xsd">

                  <!-- The datasource is bound into JNDI at this location. We reference

                     this in META-INF/persistence.xml -->

                 <datasource jndi-name="java:jboss/datasources/sample-multi-tierDS"

                    pool-name="{artifactId}" enabled="true"

                    use-java-context="true">

                      <connection-url>jdbc:mysql://localhost:3306/mydatabase?useUnicode=true&amp;autoReconnect=true&amp;characterEncoding=UTF-8</connection-url>

                      <driver>com.mysql</driver>

                      <security>

                          <user-name>username</user-name>

                          <password>password</password>

                      </security>

                 </datasource>

              </datasources>

               

              Did you install mysql driver to JBoss modules/com/mysql/main subdirectory?

               

              <module xmlns="urn:jboss:module:1.0" name="com.mysql">

                <resources>

                  <resource-root path="mysql-connector-java-5.1.21-bin.jar"/>

                </resources>

                <dependencies>

                  <module name="javax.api"/>

                </dependencies>

              </module>

               

              Your task-persistence-JPA1/2 is connected to an Oracle server. Is this tasks for Oracle-MySql synchronization? Did you installed oracle drivers, too?

                Yes, the problem was the connection to the datasource. I used AS7 but in the config file there was a link to a xxx-ds.xml file, and it belongs to AS5. I switched it to a JBMOrm,xml file and now it is working fine.

                 

                Thanks for your help!
