Karaf: Connection refused (Corporate Proxy but proxy is correctly configured in Karaf/Maven)

I'm sitting behind a coorporate proxy that has its own certificate. E.g. when I want my Java runtime to be able to communicate with the outer world I need to import my "coorporate certificate" to the Java truststore e.g. with keytool -import -keystore %JAVA_HOME%/jre/lib/security/cacerts -trustcacerts -file coorp-cert.crt

How do I import this certificate to Apache Karaf (4.3.0)?

Background: I cannot install features into Karaf. E.g. karaf@root()> feature:repo-add ecf results in the error Error executing command: Connection refused: connect : [...]. The proxy is configured correctly (tested with maven:summary which displays valid "HTTP Proxies" values). So I suspect the missing proxy certificate is causing this problem.

Solution

  • Okay, although the commands http:proxy-list and maven:summary displayed the correct proxy settings, I fixed the problem by appending -Dhttps.proxyHost=<proxy url> -Dhttps.proxyPort=<proxy port> in the line starting with set DEFAULT_JAVA_OPTS in the $KARAF_HOME/bin/karaf.bat file. Alternatively one can probably set the JAVA_OPTS or EXTRA_JAVA_OPTS variables before starting karaf (haven't tested the latter, though).

    The certificate apparently wasn't the problem.
