Hi All
I have developed a web services. I am
getting problem when two different user are trying to access web services concurrently.
In web services two methods are there
setInputParameter
getUserService
suppose
Time User Operation
10:10 am user1 setInputParameter
10:15 am user2 setInputParameter
10:20 am user1 getUserService
User1 is
getting result according to the input parameter seted by user2 not by ( him own )
I am using axis2 1.4 ,eclipse ant build,
My services are goes here
User class
service class
service.xml
build file
testclass
package com.jimmy.pojo;
public class User {
private String firstName;
private String lastName;
private String[] addressCity;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String[] getAddressCity() {
return addressCity;
}
public void setAddressCity(String[] addressCity) {
this.addressCity = addressCity;
}
}
[/code]
[code=java]package com.jimmy.service;
import com.jimmy.pojo.User;
public class UserService {
private User user;
public void setInputParameter(User userInput) {
user = userInput;
}
public User getUserService() {
user.setFirstName(user.getFirstName() + " changed ");
if (user.getAddressCity() == null) {
user.setAddressCity(new String[] { "New City Added" });
} else {
user.getAddressCity()[0] = "===========";
}
return user;
}
}
