在Windows的squid代理后面运行的Java servlet应用程序

Question

I'm behind a squid HTTP proxy requiring authentication and want to make API requests to an external server. However when I do so, I get the following error :

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.0 407 Proxy Authentication Required"

I've tried setting the proxy configuration by going to Control Panel > Java > Network Settings, but to no avail. How to solve this?

Answer 1

You should set the proxy-settings in java.

System.getProperties().put("http.proxyHost", "someProxyURL");
System.getProperties().put("http.proxyPort", "someProxyPort");
System.getProperties().put("http.proxyUser", "someUserName");
System.getProperties().put("http.proxyPassword", "somePassword");

Answer 2

Copy from http://www.it.iitb.ac.in/~roshan/articles/javahttpproxy.html :

Tomcat Settings: catalina.properties

Append these properties to the catalina.properties file in Tomcat: ${CATALINA_OME}/conf/catalina.properties file:

http.proxyHost=yourProxyURL http.proxyPort=yourProxyPort http.proxyUser=yourUserName http.proxyPassword=yourPassword Tomcat Settings: catalina.bat

Add all the parameters defined above in the ${CATALINA_HOME}/bin/catalina.bat (for Windows) or ${CATALINA_HOME}/bin/catalina.bat (for *nix): JAVA_OPTS="-Dhttp.proxyHost=yourProxyURL ..." (Each option is seperated by spaces.)
