How do i configure the http transport connector to use a proxy?

[j0llyr0g3r <ti...@wincor-nixdorf.com>]

Hi folks,

after i have figured out this problem (will be updated in the AMQ
documentation soon):

http://www.nabble.com/Standard-http-connector-example-not-working--td16937377s2354.html

i am having a new problem:

How do i configure the http transport connector to use a proxy?

I looked into the source-code and found this:

-> package:
activemq-optional/src/main/java/org/apache/activemq/transport/http
-> Class HttpTransportSupport 

There is:

private String proxyUser;
private String proxyPassword;


and in class:HttpClientTransport 

there is:

protected HttpClient createHttpClient() {
       HttpClient client = new HttpClient();
       if (getProxyHost() != null) {
           client.getHostConfiguration().setProxy(getProxyHost(),
getProxyPort());
       }
       return client;
   }

So, obviously i can use a http-proxy with AMQ, but how?

First i thought via something like adding this 

....?trace=true&proxyHost=sdoesmon&proxyPort=3128"

to the network connector:

<networkConnector name="outbound_http"
uri="static://(http://esf-proto-2:61617)?trace=true&amp;proxyHost=sdoesmon&amp;proxyPort=3128"
networkTTL="5"/>


But the broker simply ignores this?

I checked this using the latest amq stable release and squid.

The two brokers can communicate with each other over http, but they simply
ignore the proxy.

I set the debug level in both the brokers and squid to the highest value,
neither do i get errors nor is the proxy used at all.

What do i have to add to the http-connector to make this work?

Hi folks,

i finally got it working like this:

Broker 1:

    <transportConnectors>
       <transportConnector name="inbound_openwire"
uri="tcp://localhost:61616"/>
       <transportConnector name="inbound_http"    
uri="http://0.0.0.0:61617"/>
    </transportConnectors>

    <networkConnectors>
      <networkConnector name="outbound_http"
uri="static://(http://broker-2:61617?proxyHost=myProxy&amp;proxyPort=3128)"
networkTTL="5"/>
    </networkConnectors>


Broker 2:


    <transportConnectors>
       <transportConnector name="inbound_openwire"
uri="tcp://localhost:61616"/>
       <transportConnector name="inbound_http"    
uri="http://0.0.0.0:61617"/>
    </transportConnectors>

    <networkConnectors>
      <networkConnector name="outbound_http"
uri="static://(http://broker-1:61617?proxyHost=myProxy&amp;proxyPort=3128)"
networkTTL="5"/>
    </networkConnectors>


Squid:

-> without authentication

Consumer:

ant consumer -Durl=tcp://broker-1:61616

Producer:

ant producer -Durl=tcp://broker-2:61616

If i stop the squid-proxy -> no messages are delivered anymore

If i restart the squid-proxy -> messages are delivered 

So, i guess it works......

One last issue:

I can not pass parameters in the URI like:

?proxyHost=myProxy&proxyPort=3128

The broker gives me the following error on startup:

ERROR: java.lang.RuntimeException: Failed to execute start task. Reason:

Instead i have to use:

?proxyHost=myProxy&*amp;proxyPort=3128

(Minus the "*" because the mailing-list won't show this part of the string.)

According to the Jira-entry here:

-> https://issues.apache.org/activemq/browse/AMQ-1099

this should not be necessary.

Any ideas?
