Tomcat and proxy settings

Question

There is a servlet running on tomcat7 and it makes a webservice call to a third party website. The call works fine from the windows machine but when run from tomcat it fails. Wont Tomcat automatically use the Windows' proxy settings? I added

set JAVA_OPTS=%JAVA_OPTS% "-Dhttp.proxySet=true"
set JAVA_OPTS=%JAVA_OPTS% "-Dhttp.proxyHost=IP"
set JAVA_OPTS=%JAVA_OPTS% "-Dhttp.proxyPort=8080"

to CATALINA.BAT and

http.proxyHost=IP
http.proxyPort=8080

to catalina.properties But still there is no change. How do we set Tomcat to use the proxy settings of windows and is there a way to check if tomcat is picking up the proxy settings specified?

Answer 1

I do not agree with the usage of java.net.Proxy.

What happens if you need to change it ? New build, new release. The setting of the proxy should be easy. It works well with both system properties or tomcat JAVA_OPTS. I used it in both ways. Just pay attention and be sure you know what JAVA_OPTS are loaded, what java is used and so on, because there are tomcats that have their own java version. Regardint the previous post, there is no way java can be used before was loaded :). So Tomcat cannot use it before the system properties are used...only if tomcat uses another JRE that does not read system properties.

I just test this setup :

set "JAVA_OPTS=%JAVA_OPTS% -Dhttp.proxyHost=proxy.com -Dhttp.proxyPort=8080 "

in catalina.bat and works well.
