As you have seen, JMeter is based on request-response samplers. However, the BeanShell integration offers the flexibility to extend JMeter. Or of course you can write your own sampler (or any other element) from scratch. In this case, the easiest might be to use a BeanShell Sampler (or Pre-Processor if you are not interested in the time taken) to read from the socket. Or amend the existing TCPClientImpl class to create your own version that does not send anything and only exits when it sees FOO. Then use the normal HTTP sampler. I'm assuming here that the XML socket is not used for the HTTP request. > Thanks > -Geoff > > > - > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > > - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Can JMeter be used with XML datastreams over sockets?
Hi all, I am interested in a variety of loadtesting products to loadtest the following specific example: A user (client) connects to a TCP socket and constantly reads an XML stream from it. When a certain XML message is found: e.g. "", the user then requests a normal HTTP webpage. I need to ramp this scenario up to 1s of users. "XML-event based spikes" i guess you could call it. Is there anything in or associated with JMeter that could help me with this? I have looked across the site already and found for example TCP controllers and Beanshell controllers, but it seems that everybody with examples or usage of these have used them with a request-response model (i.e. open a socket send some data, receive some data), rather than a read-request (eventbased) model such as i describe (i.e. constantly read the xml stream in the background and fire off some http requests if is read) I just wondered if anybody could point me in the right direction or is JMeter not really the thing to use here?

Re: SQL call returns header as the first line
Thank you,
I added and if processor, if {$data} != COUNT NEXT STEP
That worked

RE: JMS in combination with authentication
Hi,
We have used the JMS sampler with authentication with WebLogic and it
(nearly) works - I think what we have done should be applicable for you as
well. The "nearly" is because we have had to open a support case with BEA
on
an issue we are having with JMS authorisation (i.e. after authentication),
but I dont think this will affect you.
Anyway, what we needed to do to use authentication was to add the
properties
for authentication to the JNDI properties section of the JMS sampler.
The properties we added were "java.naming.security.principal" (username)
and
"java.naming.security.credentials" (password).
If you look at the JMeter code, you will see it adds all properties from
this
section to the Initial context, so you shouldn't have to change the code
at
all.
Note - the two properties we are adding correspond to the values of the
Java
static variables Context.SECURITY_PRINCIPAL and
Context.SECURITY_CREDENTIALS.
If we were coding a standalone Java client to connect our JMS server,
these
are the variables we would reference when supplying authentication
details.
Eg. -
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, "http://127.0.0.1:7001";);
env.put(Context.SECURITY_PRINCIPAL, "weblogic");
env.put(Context.SECURITY_CREDENTIALS, "weblogic");
InitialContext ic = new InitialContext(env);
QueueConnectionFactory qconFactory = (QueueConnectionFactory)
ic.lookup("myConnFact");
QueueConnection qcon = qconFactory.createQueueConnection();
qsession = qcon.createQueueSession(false, Session.AUTO_ACKNOWLEDGE);
QueueSession queue = (Queue) ic.lookup("myQueue");
QueueSender qsender = qsession.createSender(queue);
I'm not familar with MQSeries, but if that Java code would look different
for
you JMS clients, then you'll need to adjust the way you use the JMS
sampler
accordingly.
Hope this helps - let me know how you get on!
Regards,
Adrian

Subject: JMS in combination with authentication
Hello JMeter users,
I have figured out how to send JMS messages to IBM MQSeries. We can send
messages to a queue manager which is not secured with a user and a
password.
The trick is easy:
- use the com.sun.jndi.fscontext.RefFSContextFactory class as initial
context factory with a url to the JNDI repository;
- use IBM JMSAdmin tool to create a JNDI mapping between your JMS world
and the MQ world in your JNDI repository;
We are trying to take it a step further by sending a message to a
queuemanager that has a user and a password set.
Unfortunatly we have been struggling with getting it to work for a two
days now after having tried various approaches.
I can see in the source of jmeter that all calls to the queue connection
factory are of the type:
public QueueConnection createQueueConnection() throws JMSException
Am I right that I will have to modify the code of jmeter to get it to
supply the user and password. Like as in:
public QueueConnection createQueueConnection(String userName, String
password) throws JMSException
Can anyone advise me on what to do next?
Thanx / Met Vriendelijke Groet,
Ronald van de Kuil
