Question

我有这个网络服务：


    /**
     * Web service operation
     */
    @WebMethod(operationName = "executeCleanAndValidateExtractedDate")
    public boolean executeCleanAndValidateExtractedDate()
    {
        try
        {
            CleanAndValidateExtractedData cav = new CleanAndValidateExtractedData();
            Transformation transformation = new DefaultTransformation();
            Step s1 = transformation.addStep(cav);          
            return transformation.execute();
        }
        catch (RuntimeException ex)
        {
            Logger.getLogger(ExecuteKeymark.class.getName()).log(Level.SEVERE, null, ex);
            return false;
        }
        catch(Exception ex)
        {
            Logger.getLogger(ExecuteKeymark.class.getName()).log(Level.SEVERE, null, ex);
            return false;
        }
    }

当我尝试执行它时，我得到一个例外：

javax.ejb.EJBException
    at com.sun.ejb.containers.BaseContainer.processSystemException(BaseContainer.java:5193)
    at com.sun.ejb.containers.BaseContainer.completeNewTx(BaseContainer.java:5091)
    at com.sun.ejb.containers.BaseContainer.postInvokeTx(BaseContainer.java:4879)
...
Caused by: java.lang.NoClassDefFoundError: com/medallion/etl/impl/AbstractStepSupport

我很困惑为什么它能找到那个班级。它在运行时可用，但不再可用。我需要做一些特殊的事情来部署它，以便它可以访问Glassfish中的类吗？

Answer 1

确保将所需的jar文件捆绑在war / ear文件中，以便它们在运行时可用，而不仅仅是在编译时。

NoClassDefFoundError：与Glassfish的文件打包有关？
