How to configure a proxy for WSO2

Hi, Please refer [1]. This post has details on how this could be done. This change should be done to the axis2-client.xml found in the conf directory. Thanks, Keith. Blog : http://www.keith-chapman.org [1] http://www.keith-chapman.org/2008/10/how-to-run-axis2-behind-proxy-and.html

Thanks that kind of helped. But i still got a problem...

was found. Anyway I still dont get a authentification. My username and password are correct. Is there an other way to set my proxy? regards Kruettli

The reason could well be https://issues.apache.org/jira/browse/AXIS2-4050. You might have to use the nightly build to get this fix. This has been fixed in the trunk. Thanks, Keith. Blog : http://www.keith-chapman.org/

Hi Nightly built does not work at all. I tested 259 and 257, neither did even start:-( In addition I tryed JDK 1.5 and 1.6. Same result. Any idea what could cause this issue? I allways get a Windows error during installation (the part where the commandline is active) and everytime I try to start my PC... Thanks for helping me regards Kruettli

Hi My proxy now almost works. I took two different Javascripts to test my proxy functionality. The first one worked fine, the other one did not. The first script was developed within WSO2 Mashup Server (WSO2 Yahoo GeoCode) The second is a scraping script, have a look please: ____________________________________________________ function getString(){ var config = ; var scraper = new Scraper(config); var result = scraper.response; return result; } ____________________________________________________ Now the result I get if I execute this script on my WSO2 Server is as follows: ____________________________________________________ Fault: Transport error: 503 Error: Service Unavailable [detail] org.wso2.mashup.MashupFault: Transport

____________________________________________________ What can I do now? Does WSO2 use different Proxy settings for scraping and API usage? Regards Kruettli

The scraper uses the same proxy configuration which is picked from axis2-client.xml. When proxy information is present, all request sent out of the Mashup Server will use it. Thanks, Keith. Blog : http://www.keith-chapman.org/
