Hello
I have created a proxy service in WSO2 2.0 which connects to a an external web service, but when i try to start the ESB from my university I cannot start it. the Server console states

I believe this is a problem that occur because i am behind a proxy, For when i have a direct connection to the internet no problem at all.
I tried appending "-Dhttp.proxyHost=192.168.1.10 -Dhttp.proxyPort=3188" to the JAVA_OPTS in the wso2server bat file still no use.
I need more information from you on what exactly is the proxy server software you use etc. Also, can you get a trace through TCPMon for a request passing through your proxy?
I really need more information to pin point any issue and help you on this :-)
Can you check from your IT department on the proxy server your company uses? Also, can you let me know the URL of the service you try to access through the ESB? You may send this information privately to me if you do not want to share this publicly
i have the ESB, the client and the server in the same machine. This machine no have a direct acces to Internet. All conection pass trought a router. Firefox and i.e. are configurated to pass the router. I am looking for a way to configure ESB to pass through the router. It's all :S
But it through a Error when I try to put a external webservice to prove the system: (http://webservices.iter.dk/calculator.asmx?WSDL)

For this, you could configure the ESB to use your proxy services. See http://java.sun.com/j2se/1.5.0/docs/guide/net/proxies.html for more details
Basically you will start the ESB (by editing the start scripts) to use the system properties "-Dhttp.proxyHost=webcache.mydomain.com -Dhttp.proxyPort=8080"
I have had problems after amend whatYou said. Look, this happens when I try to access a webservice outside:

OK.. now this happens as the NIO based http/s transport is not aware of the non-transparent proxy server. Let me look at possible solutions and get back to you.. when you originally posted this question, I assumed you wanted this - but then the problem you had was getting the WSDL of the external service - which does not take place over the NIO http/s transport
However, if you configure your proxy as a transparent proxy - this will work fine as it is in your environment.. is this a possibility?
