    Quartz clustering problem with JDBC-JobStores

      Hi

       

      I am using jboss application server which has quartz as service. I have deployed Quartz as service and all quartz related library are present in server/xxx/lib folder. When I am using JDBC-JobStores then Trigger gives error while retrieving the job

       

      Following is the error

      Error retrieving job, setting trigger state to ERROR.
      org.quartz.

      JobPersistenceException: Couldn't retrieve job because a required class was not found:com.myjob

      Does any body help me on that how do i resolve this issue. I think it is the problem with classloader. do I miss some configuration related to quartz or jboss.

          I solved this problem by using custom class loader. Following are the definition of custom classloading in war folder

           

          <?xml version="1.0" encoding="UTF-8"?>
          <classloading xmlns="urn:jboss:classloading:1.0"
                        name="mv-web.war"
                        domain="DefaultDomain"
                   top-level-classloader="true"
                        export-all="NON_EMPTY"
                        import-all="true">
          </classloading>

           

          Now quartz is getting the job class and working fine.

           

           

          Now I have another problem with this.

           

          Since I am using jboss clustering, lcds clustering. LCDS clustering is not working after applying custom classloader.

          It seams both cluster trying to send data to each other.

          When I change the custom classloading it works fine

           

          can any body let me know where i am wrong.
