Hi guys,

I'm creating a web service application that uses hibernate. I created 2 java class namely Tbl_Member and Tbl_Dependents. Both of the classes comes with their own respective mapping file (hbm.xml). Now my problem is when i try to build my project (using netbeans 5.5), my compiler throws an error. Here's the error message when i tried to build my project in netbeans:

Here's the definition of my class file (Tbl_Members) and its mapping file:


public class Tbl_Members {
private String memid_no;
private String batch_id;

//other private variables

private java.util.Set dependents = new java.util.HashSet();

/** Creates a new instance of Tbl_Members */
public Tbl_Members() {
}

public String getMemid_no() {
return memid_no;
}

public void setMemid_no(String memid_no) {
this.memid_no = memid_no;
}
//other setter getter methods

public java.util.Set getDependents() {
return dependents;
}

public void setDependents(java.util.Set dependents) {
this.dependents = dependents;
}
}

Now, I was thinking if the error that i received (when i compile my project) is caused by my application being a web service project in my netbeans. I have heard that there are some limitations in datatypes when deploying a web service. If so, is the java.util.Set is one of the limitations in a web service application? What are the possible workaround if that's the case?
Or is there is something that I just missed out?
