Threadsafe servlet code?

Question

Hi,
Im developing a sevlet accesing an enterprise system using HTTP. I am using the Apache HttpClient package and have a questing regarding thread safety. The classes are like below:
EnterpriseClient.java:
public class EnterpriseClient
private HttpClient client;
MultiThreadedHttpConnectionManager connectionManager = null;
public void create()
// create a thread safe HttpClient.
connectionManager = new MultiThreadedHttpConnectionManager();
client = new HttpClient(connectionManager);
public String getEnterpriseData(String msisdn)
PostMethod post = new PostMethod("....");
String result = post.getResponseBodyAsString();
return result;
public String setEnterpriseData(String msisdn, Strign data)
PostMethod post = new PostMethod("....");
post.setMessageBody(data);
String result = post.getResponseBodyAsString();
return result;
EnterpriseServlet.java:
public class EnterpriseServlet extends HttpServlet {
EnterpriseClient myClient = null;
public void init() throws ServletException
myClient = new EnterpriseClient ();
myClient .create();
public void doPost(...) {
// get enterprise data
String reply = myClient.getEnterpriseData(id);
// analyze data
// set enterprise data
String reply = myClient.setEnterpriseData(id, data);
Would this code qualify as thread safe? This is not the actual code, just used to illustrate the design.
HttpClient docs: http://jakarta.apache.org/commons/httpclient/preference-api.html
Any input would be appreciated.

I don't know the design or intention of the HttpClient but the way you have it designed now is that all users and threads share the same myClient object. Is that what you expected?
