Build Identifier: 20110615-0604 I'm having problem with internet connection within Eclipse (using Eclipse Modeling Tools x64). When I click install new software or install modeling components, I get the following message: "We can't connect to the discovery source, make sure you're connected to internet and try again." And the following is Exception Stack Trace: java.lang.RuntimeException: java.net.ConnectException: Connection timed out: connect at

at org.eclipse.amalgam.discovery.modeling.handlers.ModelingDiscoveryHandler$1.load(ModelingDiscoveryHandler.java:58) ... 44 more My internet is working fine and EclipseMDT works well on my laptop, but it does not work on my desktop. My desktop is connected to internet wirelessly via USB device. That wasn't a problem though. I hooked up my modem directly to my desktop to see if the USB device was the problem, but it was not. Reproducible: Always Steps to Reproduce: 1. Click install Modeling Components or install new components. 2. Error message on a pop-up window 3.
I can confirm this. Altough I don't get a time out, I can't even connect. I am behind a company firewall/proxy, however, I have no problems connecting to the Internet from Eclipse otherwise (e. g. updates, javadoc, etc.). Is there an issue with Amalgam not honoring the proxy settings, perhaps? It's also unfortunate that the error message does not give any indication as to which URL the connection attempt was made to. Thus there is no way to check if there actually _is_ some kind of connection problem to the discovery source. There may be a content filter in place on my firewall/proxy. However I doubt that. Thus I suggest catching java.net.ConnectException at org.eclipse.amalgam.discovery.modeling.handlers.ModelingDiscoveryHandler$1.load(ModelingDiscoveryHandler.java:63) and printing an error message including the URL tried to the error log as a first step to solve the issue. I had the problem in 4.3M4, and updating to 4.3M5 (just did it via p2, so I do have internet connectivity from eclipse!) didn't fix it.

Thanks for your feedback. The file the discovery is trying to access is an XMI file stored on the eclipse http server. We are using EMF to load it. I assumed EMF was respecting the Eclipse proxy settings but based on your report it probably does not. I'll digg further.
Here is an update site containing a first fix : https://hudson.eclipse.org/hudson/job/amalgam-1.2.0/275/artifact/features/org.eclipse.amalgam.update/target/org.eclipse.amalgam.update.zip I don't have a proxy myself so I had not really tested yet, feel free to have a try and tell me .
I checked that defining a bogus proxy leads to the catalog not being resolved. This change will be part of the Kepler RC2 release, feel free to re-open if it is not fixing your problem.
