copied!<p>Ive had a similar question as this one before, and when that solved this came. So here we go again.</p> <p>The content of doGet pretty much works but when I try it as a part of a servlet that eclipse created for me I get errors. Its looks a bit like I don't have the appropriate files referenced in the library, but I think I do.</p> <p>The java code looks like this:</p> <pre><code>package picasatest; import java.io.IOException; import java.net.URL; import javax.servlet.http.*; import com.google.gdata.client.photos.PicasawebService; import com.google.gdata.data.photos.AlbumEntry; import com.google.gdata.data.photos.UserFeed; @SuppressWarnings("serial") public class PicasaTestServlet extends HttpServlet { public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException { resp.setContentType("text/plain"); try { PicasawebService service = new PicasawebService("Picasa test"); service.setUserCredentials("username@gmail.com", "password"); URL feedURL = new URL("http://picasaweb.google.com/data/feed/api/user/username?kind=album"); UserFeed feed = service.getFeed(feedURL, UserFeed.class); for (AlbumEntry entry : feed.getAlbumEntries()) { System.out.println(entry.getTitle().getPlainText()); } } catch (Exception e) { e.printStackTrace(); } } </code></pre> <p>}</p> <p>I have referenced to google-collect-1.0-rc2.jar, mail.jar, activation.jar, servlet-api.jar, gdata-client.jar, gdata-client-meta.jar, gdata-core.jar, gdata-media.jar, gdata-photos-2.0.jar and gdata-photos-meta-2.0.jar according to instruction from <a href="http://code.google.com/apis/gdata/articles/eclipse.html" rel="nofollow noreferrer">google</a>. Is there anything else I have to do for it to work?</p> <p>And I get this error to the console:</p> <pre><code>java.lang.NoClassDefFoundError: com/google/gdata/client/photos/PicasawebService at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2357) at java.lang.Class.getConstructor0(Class.java:2671) at java.lang.Class.newInstance0(Class.java:321) at java.lang.Class.newInstance(Class.java:303) at org.mortbay.jetty.servlet.Holder.newInstance(Holder.java:153) at org.mortbay.jetty.servlet.ServletHolder.getServlet(ServletHolder.java:339) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:463) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1093) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java:43) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) at com.google.appengine.tools.development.StaticFileFilter.doFilter(StaticFileFilter.java:124) at org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1084) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:360) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:712) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) at com.google.apphosting.utils.jetty.DevAppEngineWebAppContext.handle(DevAppEngineWebAppContext.java:54) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) at com.google.appengine.tools.development.JettyContainerService$ApiProxyHandler.handle(JettyContainerService.java:313) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:139) at org.mortbay.jetty.Server.handle(Server.java:313) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:506) at org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete(HttpConnection.java:830) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:514) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:211) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:381) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:396) at org.mortbay.thread.BoundedThreadPool$PoolThread.run(BoundedThreadPool.java:442) </code></pre> <p>Any idea on what I have missed?</p>
