Recording from J2ME WTK App
Hi All,
I'm trying to use the Recording Proxy to capture the traffic from our client (a J2ME app which uses HTTP) to our server. I've set up JMeter (2.3.2) correctly and when I enable my browser to user the JMeter proxy (as a test) it successfully records requests.
I've set the proxy settings in the Wireless Toolkit (Sun, 2.5.2) and run the emulator. Traffic is hitting the proxy but I'm getting "[Sample Failed]" and "Cannot handle CONNECT - probably used HTTPS". I'm not using HTTPS , all the traffic is HTTP. From looking at the code, the problem seems to be that the JMeter proxy won't handle a CONNECT request (I've substituted the url):
2009/05/19 13:50:45 DEBUG - jmeter.protocol.http.proxy.HttpRequestHdr: browser request: CONNECT <the url>:80 HTTP/1.1
2009/05/19 13:50:45 DEBUG - jmeter.protocol.http.proxy.HttpRequestHdr: parser input: CONNECT <the url>:80 HTTP/1.1
2009/05/19 13:50:45 DEBUG - jmeter.protocol.http.proxy.HttpRequestHdr: parsed method: CONNECT

at org.apache.jmeter.protocol.http.proxy.HttpRequestHdr.parse(HttpRequestHdr.java:164)
at org.apache.jmeter.protocol.http.proxy.Proxy.run(Proxy.java:165)
Any thoughts on how to get around this problem?

I don't know how much work it is to set up a real proxy so I think it would be more wise to spend my time picking up the traffic model with Wireshark and manually inputting it into JMeter.
There are several proxies that are quite easy to set up.
For example:
http://wiki.apache.org/jakarta-jmeter/NetworkSniffer
Try TCPMon.
If the requests are not all that complicated, you can record the URLs
in a file and use CSV Dataset to read them. Full URLs can be used in
the HTTP Path: field.
It gets a bit more complicated for POST requests, unless these always
have the same number of parameters.

Hi,
Thanks for you input sebb. I was planning to use it for building a traffic model for use in performance testing, which is due to start tomorrow. I don't know how much work it is to set up a real proxy so I think it would be more wise to spend my time picking up the traffic model with Wireshark and manually inputting it into JMeter.
For what it's worth, this seems to be the answer to my question:

The WTK tunnels both HTTP and HTTPS, so unfortunately it won't work. There is a code workaround posted in that link so I might be abe to convince the developers here to stick it in for me ;)

JMeter Proxy does not support CONNECT; I doubt it ever will, as it is
not intended as a general-purpose proxy.
Not sure why the application should be sending a CONNECT for HTTP;
perhaps it is due to the way the proxy was set up? Maybe because the
Sun toolkit is wireless, it uses CONNECT to tunnel SSL over HTTP?
You could try using a "real" HTTP proxy to see what traffic is
actually being sent. If that can record the requests to a file, you
should be able to use that to build up a JMeter test plan.
