NWDS 2.0.13 Startup Problem

Hello. I run WIndows XP and I have installed J2EE 1.4 SDK

Then I have installed the NWDS 2.0.13

WHen trying to start the Developer Studio I get the following message :

Problem during startup. Check the ".log" file in the ".metadata" directory of your workspace.

In the log file I find the following information, but I do not know what to do with it.

I read in another post that I could try to run in console mode (java.exe instead of javaw.exe) to read extra infos on the console, but it disappears as soon as it appears...

Any help is welcome,

    Hi Claudio,

    While installing NWDS you were asked for Proxy settings. Andf i guess you have not specified anything there. Because of that it gives such error.

      Great it worked! In the above mentionned file the two following lines were already present:



      Both with nothing after the = sign.

      I replaced the first with a fake proxy address as below


      And the NWDS 2.0.13 finally started !

      The first thing I did after that was to go to menu

      WIndow / Preferences / Workbench / Proxy Settings

      and unchecked the "Use Proxy Server" checkbox.
