NoSuchMethodError while accessing a POJO

[Subhash Bhushan C]

Hi,

Had posted this in the Struts section, but decided this was a better forum to address this issue.

I have an action class ProfileDetailAction, which implements the getter/setter methods related to Profiles. I have 2 classes RegistrationAction and AlterProfileAction extending from it.

I have an EJB 3.0 entity class called ProfileDetail which is mapped to an underlying table in MySQL.

ProfileDetailAction.java:

 
    public class ProfileDetailAction extends JustBooksActionSupport {
.
.
.        
        /*** @return the firstName
 */public String getFirstName() {return firstName;}
.
.
.

RegistrationAction.java:

    public class RegistrationAction extends ProfileDetailAction {public String execute() throws Exception {
.
.
.
                //Profile Details Object
ProfileDetail profileDetail = new ProfileDetail();
profileDetail.setFirstName(getFirstName());
.
.
.

ProfileDetail.java:

@Entity@Table(name = "profile_detail")
public class ProfileDetail implements java.io.Serializable {
.
.
.
private String firstName;
.
.
.
public void setFirstName(String firstName) {
this.firstName = firstName;
}
.
.
.

The firstName variable in ProfileDetail action is getting filled properly (I am able to see them in debug mode.)
When setFirstName() gets called in RegistrationAction, I get the following error:

java.lang.NoSuchMethodError: com.justbooks.entities.ProfileDetail.setFirstName(Ljava/lang/String

I am not sure whether this is a classloader problem, or I am doing something wrong. I am using JBoss, with MySQL DB. I am using Eclipse, and the IDE does not throw up any errors too.

I have only one Java version on my laptop, jdk1.5.0_01, which is being used by both Eclipse (my IDE) and JBoss (my App Server). I saw quite a number of posts on the net indicating it might be a version mismatch. But I dont think that applies to this situation.

Any clue welcome...

try changing "firstName" to "firstname"

Would that actually matter ?

You guys wont believe what the problem was...
JBoss was not replacing old class files with new files in a new EAR. So, the first version of the file was being reference. Once I cleaned up the deployment directory, everything worked just fine...

Thanks for the help, Anand...
