I'm trying to run the sample program, which comes with Google Data API. I get a runtime error at following line

YouTubeService myService = new YouTubeService("gdataSample-YouTube-1");

The error is the following:

run:

Java Result: 1

I tried both Google Data API versions 1.35.0 and 1.35.1, and I get the same error in both cases.

Looks like you don't have the collections library in your class path.

It's in the gdata/java/deps directory in the zip file. Include the google-collect-1.0-rc1.jar file in your classpath and you should be fine. (You may also need jsr305.jar - I'm not sure.)

  • i tried to download google-collect-1.0-rc1.jar ,from http://code.google.com/p/gdata-java-client/source/browse/#svn/trunk/java/deps, but i get a file of only 32 kb when the actual size shown on that site is 535 kb is there any other location when i can get this file? Can u mail it to me. my email id is mindedges@gmail.com – user93796 Aug 11 '09 at 08:49
  • You don't need to download it separately - it's in the GData API zip file. – Jon Skeet Aug 11 '09 at 08:58
