Problem NoClassDefFoundError: weblogic/cmp/rdbms/PSRdbms_Base


EJB programming & troubleshooting: Problem NoClassDefFoundError: weblogic/cmp/rdbms/PSRdbms_Base

  1. Hi

    I am working in EJB entity bean using a Serializable value object. Once i created the jar file and complied the code using ejbc. Everthing going fine. While i am deploying the my jar its giving the error is
    NoClassDefFoundError: weblogic/cmp/rdbms/PSRdbms_Base and
     A class that the bean or interface classes depend on
    is not in the EJB jar file or the classpath.

    I will explain my procedure here.
    My value object is
    package userValue;

    public class UsersData implements Serializable {

      private String strUserName;
    public UsersData()
    public UsersData(String strUserName)
    this.strUserName = strUserName;

      public int getUserName() {
        return this.strUserName;
    public void setUserName(String strUserName) {
        this.strUserName = strUserName;
    THis is about value object. I am impleting usersdata in ejb bean. I will write my code here.

    package userValue;
    import userValue.*;

    public class UserValueEJB implements EntityBean
    //public class UserValueEJB extends UsersData implements EntityBean

    public UserValuePK ejbCreate(UsersData ValueObjUser) throws CreateException
    { this.userid = ValueObjUser.getUserId();
    this.username =ValueObjUser.getUserName();
    this.password = ValueObjUser.getPassword();
    this.secretquestion = ValueObjUser.getQuestion();
    this.secretanswer = ValueObjUser.getAnswer();
    this.usertype = ValueObjUser.getUserType();
    this.email1 = ValueObjUser.getEmail1();
    this.email2 = ValueObjUser.getEmail2();
    return (null);

    THis is about my code. I set classpath and i put the complied in to c:\weblogic\myserver\severclasses as package name. WHile deployment i am facing this problem saying NoClassDefFoundError. Please explain where exactly i am facing problem. Is there any problem for using Value object.

    Please explain in detial where i am facing problem. Please explain imm this urgent requirment for client. If you can make a call please make call to 408 441 1490.
