    Wildfly Datasource ClassCastException

    Nabeel Bukhari Newbie

      I am working on project which needs to be deployable on both weblogic and jboss. I have compiled WildFly Beta 2 from sources. Now, I am trying to get datasource using naming. In JBOSS EAP 6.1, I was able to get datasource instancce casted as javax.sql.DataSource, but now it if I try to cast the WrapperDataSource to javax.sql.DataSource as following:

      dataSource = (javax.sql.DataSource) context.lookup("datasource");

      , it throws

      java.lang.ClassCastException: org.jboss.jca.adapters.jdbc.WrapperDataSource cannot be cast to javax.sql.DataSource

      if I try using following code,

      Object obj = context.lookup("datasource"); dataSource = (javax.sql.DataSource) obj;

      it doesn't throw the above exception rather on using the datasource, it throws exception

      Caused by: java.lang.IncompatibleClassChangeError: Class org.jboss.jca.adapters.jdbc.WrapperDataSource does not implement the requested interface javax.sql.DataSource

      However, looking at code of class, we can see that it implements the javax.sql.DataSource

      What else configuration is required to use casted WrapperDataSource or get datasource returned as javax.sql.DataSource.

          javax.sql.DataSource is part of Java runtime.

          Do you have something in your deployments unit which brings in another version of this interface?

            Hi Frank

             

            Thanks for responding, I have multiple jdks installed but JAVA_HOME is set to C:\Progra~2\Java\jdk1.7.0_40\bin\java and WildFly is running using same JDK.

             

            Here are the logs from server:

            I have configured DB2 driver as static module under modules directory. It doesn't seem to confilct with any other.

             

            One more thing, if I debug using eclipse and try to inspect on the code it doesn't throw any exception but if I try to step-on then it throws exception. This behaviour is really strange

              I think just your lookup is wrong.

               

              try looking up "java:/rapiddb"

               

              you can also inject datasource by doing

               

              @Resource(lookup="java:/rapiddb")

              DataSource datasource;

                Hi Tomaz,

                 

                I am trying to lookup like context.lookup(filedata[5]); where filedata is an array and containing some parameters. I wrote it as context.lookup("datasource"); for simplicity. I cannot use @Resource as the above class is not a bean. Its a singletion class working on native sql.

                  I created a singleton bean and injected datasource by doing

                   

                  @Resource(lookup="java:/rapiddb")

                  DataSource datasource;

                   

                  when trying to get datasource using getter, I found the following exception seems to be same.

                  @Frank:

                  Is there any way to find if I have multiple version of interface?

                    YES, there was another jar part of my modules containing javax.sql.DataSource in it. Removing the jar name from module.xml fixed the issue.

                     

                    Thanks everyone for helping
