Webmethods:How to Kill a Running Service from the Integration Server

Many of you have wondered how to kill a WebMethods service while its running on the Integration Server.

Its become a Pet Interview Question for many but the interviewer also expects one of the following facts which is not the most recommended method to kill a running service.

Here are some facts:

1. If you are running the service on debug mode, the service will get killed if you kill your developer.
2. If you are running the service on RUN mode, the service runs on the Integration Server and will not get killed.
3. If your client has activated the service but terminated the session, the service will still run on the IS.
4. If your webmethod service is hung, You will try to Reload the entire package. But this will NOT help.
5. You will also try to unload the package but this will NOT help too.

What you need to do is on a Thread Level. The idea is quite simple: Just get the list of all the current running threads and kill the service which you need.

I will try to explain this in a step by step manner. Developers please do try it out on your dev boxes as well.

Step 1:
Create a Flow service like this:


Step 2:
Lets create a Flow service which will get ALL running threads. This should take NO input but lets output a String containing all running threads on that Integration Server.


Step 3:

Insert the following Java Code in your WebMethods Flow Service that you just created. The code is commented well enough.

// Author: Hussain Fakhruddin (hussulinux@gmail.com)
// Date: 20090128
//Get the Current Thread
Thread currentThread = Thread.currentThread();
//Get all Thread Groups.
ThreadGroup rootThreadGroup = currentThread.getThreadGroup();
//Traverse to the Top Thread Level
while (rootThreadGroup.getParent() != null) {
rootThreadGroup  = rootThreadGroup.getParent();
//Getting all Threads
Thread [] threads = new Thread[1000];
int threadCount = rootThreadGroup.enumerate(threads, true);
String threadList = “”;
// Now traverse through all the Threads and use the ServerThread API from webmethods to get all the thread detail.
int i=0;
for (; i<threadCount ; ++i){
if (threads[i] instanceof com.wm.app.b2b.server.ServerThread) {
//Casting a raw thread into ServerThread type
com.wm.app.b2b.server.ServerThread serverThread = (com.wm.app.b2b.server.ServerThread) threads[i];
//Getting the service Name for which the thread belongs to
if (serverThread.getState().getService() != null){
threadList = threadList + serverThread.getState().toString() ;
java.util.Stack threadStack = (java.util.Stack) serverThread.getState().getCallStack();
for (Iterator iter=threadStack.iterator(); iter.hasNext();) {
Object threadObj = iter.next();
threadList = threadList + “\n ” + threadObj.getClass().getName();
threadList = threadList + “, ” + threadObj.toString();
IDataCursor cursor = pipeline.getCursor();
cursor.insertAfter(“threads”, threadList);


Step 4: Now lets create another flow service “killThread” with the following inputs and outputs


Step 5: Now copy paste the following code. We’re going to traverse through the entire list and call the .interrupt() method to kill the process. Note: you need to provide FULL path of the service which you want to kill. You can get the full path from the webmethods admin panel (under package management).

// Author: Hussain Fakhruddin(hussulinux@gmail.com)
// Date: 20090128
IDataCursor cursor = pipeline.getCursor ();
if (cursor.first (“serviceName”)) {
String serviceName = (String) cursor.getValue ();
Thread current = Thread.currentThread ();
ThreadGroup root = current.getThreadGroup ();
while (root.getParent () != null) {
root = root.getParent ();
Thread [] threads = new Thread [1000];
int count = root.enumerate (threads, true);
String sb = “Not Found”;
StringBuffer killedList = new StringBuffer ();
for (int i=0; i<count; i++) {
if (threads[i] instanceof com.wm.app.b2b.server.ServerThread) {
com.wm.app.b2b.server.ServerThread serverThread = (com.wm.app.b2b.server.ServerThread) threads[i];
if (serverThread.getState ().getService () != null) {
java.util.Stack stack = (java.util.Stack) serverThread.getState ().getCallStack ();
for (Iterator iter=stack.iterator (); iter.hasNext ();) {
Object obj = iter.next ();
String name = obj.toString ();
if (name.trim().equals (serviceName)) {
threads[i].interrupt ();
sb = “Interrupted”;
killedList.append (stack.toString ()).append (“\n”);
cursor.insertAfter (“status”, sb);
cursor.insertAfter (“killedList”, killedList.toString ());
cursor.destroy ();

That’s it folks! Save and run it.. Come back to me if you face problems..

    Однако опросы показывают, что лишь 4% жителей Питера знают о такой услуге.
    По какой причине?
    Потому что частным клиникам выгоднее сдирать с людей деньги за каждое посещение.
