super();
this.employeeName = employeeName;
this.employeeAddress = employeeAddress;
this.employeePhoneNo = employeePhoneNo;
this.employeeDepartment = employeeDepartment;
}

public String getEmployeeAddress() {
return employeeAddress;
}
public void setEmployeeAddress(String employeeAddress) {
this.employeeAddress = employeeAddress;
}
public String getEmployeeDepartment() {
return employeeDepartment;
}
public void setEmployeeDepartment(String employeeDepartment) {
this.employeeDepartment = employeeDepartment;
}
public String getEmployeeName() {

}
public void setEmployeeName(String employeeName) {
this.employeeName = employeeName;

}

public EmployeeBean getEmployee(String employeeName){
EmployeeBean employeeBean = null;
for (int i = 0; i lt; this.employeeList.length; i++) {

Have you tried the DWR debug site? does the exposed DWR service(s) work from the debug site? No errors in your application server log?
