I googled it, but can't get much help,</p> <p>here is my code</p> <pre><code>public static String getGmailContactList() { String response = ""; StringBuilder str = new StringBuilder(); String statusString = ""; ArrayList list = new ArrayList(); ContactsService myService = new ContactsService(""); String email = "xxxxx@gmail.com"; String password = "xxxxxxxx"; try { try { myService.setUserCredentials(email, password); } catch (AuthenticationException ex) { ex.printStackTrace(); //****I got exception here when using this code on LINUX ENVIORMENT** *** } response = printAllContacts(myService, email); Iterator itr = list.iterator(); while (itr.hasNext()) { ArrayList contact = (ArrayList) itr.next(); try { str.append(contact.get(1)).append(","); } catch (Exception e) { log.debug("Exception ocurred inside fethching gmail contact &amp;gt; &amp;gt; &amp;gt; " + e); str.append("no contacts found"); } str.substring(0, str.length() - 1); } } catch (Exception ae) { response = statusString; log.debug("Exception ocurred inside ReadContacts : getGmailContactList()" + ae); } return response; } public static String printAllContacts(ContactsService myService, String emailSent)// throws ServiceException, IOException { URL feedUrl = new URL("http://www.google.com/m8/feeds/contacts/" + emailSent + "/full"); Query myQuery = new Query(feedUrl); myQuery.setMaxResults(100); ContactFeed resultFeed = myService.getFeed(myQuery, ContactFeed.class); String phones = null; String emails = null; log.debug(resultFeed.getTitle().getPlainText()); StringBuilder contacts = new StringBuilder(); contacts.append("&lt;?xml version=\"1.0\"&gt;&lt;Contacts&gt;"); for (int i = 0; i &lt; resultFeed.getEntries().size(); i++) { contacts.append("&lt;Contact&gt;"); ContactEntry entry = resultFeed.getEntries().get(i); if (entry.hasName()) { Name name = entry.getName(); if (name.hasFullName()) { String fullNameToDisplay = name.getFullName().getValue(); if (name.getFullName().hasYomi()) { fullNameToDisplay += " (" + name.getFullName().getYomi() + ")"; } contacts.append("&lt;Name&gt;").append(fullNameToDisplay).append("&lt;/Name&gt;"); } else { contacts.append("&lt;Name&gt;").append("").append("&lt;/Name&gt;"); } } else { contacts.append("&lt;Name&gt;").append("").append("&lt;/Name&gt;"); } StringBuilder emailIds = new StringBuilder(); if (entry.hasEmailAddresses()) { List&lt;Email&gt; email = entry.getEmailAddresses(); if (email != null &amp;&amp; email.size() &gt; 0) { for (Email e : email) { emailIds.append(e.getAddress()).append(","); } emailIds.trimToSize(); if (emailIds.indexOf(",") != -1) { emails = emailIds.substring(0, emailIds.lastIndexOf(",")); } contacts.append("&lt;Email&gt;").append(emails).append("&lt;/Email&gt;"); } else { contacts.append("&lt;Email&gt;").append("").append("&lt;/Email&gt;"); } } else { contacts.append("&lt;Email&gt;").append("").append("&lt;/Email&gt;"); } contacts.append("&lt;/Contact&gt;"); } contacts.append("&lt;/Contacts&gt;"); return contacts.toString(); } </code></pre> <p>so where I am lacking behind, some sort of help will be appriciated</p> <p>here is the stack trace</p> <pre> com.google.gdata.client.GoogleService$InvalidCredentialsException: Invalid credentials at com.google.gdata.client.GoogleAuthTokenFactory.getAuthException(GoogleAuthTokenFactory.java:660) at com.google.gdata.client.GoogleAuthTokenFactory.getAuthToken(GoogleAuthTokenFactory.java:560) at com.google.gdata.client.GoogleAuthTokenFactory.setUserCredentials(GoogleAuthTokenFactory.java:397) at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:364) at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:319) at com.google.gdata.client.GoogleService.setUserCredentials(GoogleService.java:303) at com.gmail.ReadContacts.getGmailContactList(ReadContacts.java:55) </pre>

    3. COStrange as the code is straightforward. I would suggest to download the source code of the gdata client and put breakpoints in it.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
