Add OpenSocial Gadget

Brian Rodecap (51●8●3) | asked Jan 14 '11, 12:15 a.m.
I am trying to add Sonar OpenSocial gadgets to my personal dashboard. When specifying the URL to the gadget, I get the following error...

org.apache.http.conn.ConnectTimeoutException: Connect to exogadgets.appspot.com/74.125.67.141:80 timed out

I've tried the Wikipedia example also, with the same result.

I suspect that the issue is with my proxy settings or outbound whitelist but cannot troubleshoot further. I would appreciate any thoughts or suggestions. Thanks!

If you're able to open the gadget XML in your browser, then it sounds like a firewall issue, i.e. the firewall is blocking the request from your server to the gadget. You can confirm this by doing a wget on the server and see if it goes through.

Good idea on testing using wget from the command line. I'm now certain that my proxy is the issue. Still, I cannot seem to find a way to set the proxy values in RTC.

I did find some instructions on setting up "org.eclipse.core.net.prefs" here...

http://www.mainsoft.com/jazz-doc/proxysettings

...but that didn't seem to do the trick. Any thoughts on configuring the server to work with a proxy?

I may be wrong, but I don't think RTC supports this type of proxy. Is there any chance you can open up the firewall a bit so that these requests can go through?

I'm not positive if this will work, but give it a shot. Please let us know if it works -- we should definitely document this!

Create a new text file org.eclipse.core.net.prefs in a Jazz server folder, depending on application server type:

For Apache Tomcat: JazzInstallDir/server/tomcat/work/Catalina/localhost/jazz/eclipse/workspace/.metadata/
.plugins/org.eclipse.core.runtime/.settings/

For IBM WebSphere Application Server: WASInstallDir/profiles/profile/temp/node/server1/jazz_war/jazz.war/eclipse/workspace/.metadata/
.plugins/org.eclipse.core.runtime/.settings/

Paste the following contents to org.eclipse.core.net.prefs and edit it according to you proxy configuration: 

# General proxy settings

org.eclipse.core.net.hasMigrated=true

eclipse.preferences.version=1

proxiesEnabled=true

# HTTP proxy settings

# proxyData/HTTP/host=<proxy>

# proxyData/HTTP/port=<proxy>

# proxyData/HTTP/hasAuth=false

# HTTPS proxy settings

proxyData/HTTPS/host=<proxy>

proxyData/HTTPS/port=<proxy>

proxyData/HTTPS/hasAuth=false

# Hosts that will not use proxy 

# nonProxiedHosts=<hostname1>

nonProxiedHosts=127.0.0.1|localhost


Restart the Jazz Team Server.

No chance of opening up the firewall. Any chance a feature request could be opened to configure proxy settings?

As mentioned in my previous post, the "org.eclipse.core.net.prefs" settings do not appear to work.
