Re: [appengine-java] Apache POI spreadsheet autoSizeColumn() throws NoClassDefFoundError
Hi Mathew,
POI uses GAE restricted classes.
Please refer to
http://code.google.com/p/googleappengine/wiki/WillItPlayInJava
Alternate way is to use jxl library.
Thanks
George

I'm working on an export to XLS service using Apache POI 3.6, and I've

The code:

PrintSetup printSetup = sheet.getPrintSetup();
printSetup.setLandscape(true);
sheet.setFitToPage(true);
sheet.setHorizontallyCenter(true);

for (int i = 0; i = 4; i++) {
sheet.autoSizeColumn(i); //Commenting this line out resolves the

...Whaa..? Like a good baby-java dev, I checked the GAE developers guide
as directed, but couldn't find anything useful. I upgraded to POI 3.7 for
kicks, but the error remained. Anyone have experience with POI + Excel
Spreadsheets + GAE? Anyone? ...Bueller?

Re: [appengine-java] OAuth and google chrome
Hi Chris, Solution to your problem can be fixed by moving oauthParameters.setOAuthCallback(http://myappengine/connect.jsp;); after oauthHelper.getUnauthorizedRequestToken(oauthParameters); But this is oauth 1.0 not the updated 1.0.a, means you won't receive a verifer id and will have the yellow warning message. Solution to this 1. Make no changes in step one index.jsp as you have written now. 2. In Connect jsp * String accessToken = request.getParameter(oauth_token); oauthParameters.setOAuthToken(accessToken);* oauthParameters.setOAuthTokenSecret(Unauthorizedtoken); oauthHelper.getOAuthParametersFromCallback(request.getQueryString(),oauthParameters); String accessToken =oauthHelper.getAccessToken(oauthParameters); String accessTokenSecret = oauthParameters.getOAuthTokenSecret(); Thanks George On Thu, Jan 19, 2012 at 12:46 AM, Ikai Lan (Google) ika...@google.comwrote: This is strange - there should be nothing browser specific about the session.

[appengine-java] Gmail IMAP and SMTP using OAuth
Hi Guys, Anyone knows about integrating Gmail IMAP and SMTP using OAuth on GAE. Both of them using sockets. Also if I use GAE Mail java API to send mails, from address(sender) becoming an issue as only the app developers email address can be added. Basically my app is integrated to Google APPS and I am looking to send mails on behalf of the logged in user. Any thoughts on this?

[appengine-java] Re: built in security features of GAE
Thanks Jason. We are migrating our apps to GAE in 2-3 months, so our customers may ask some of the security measures. Though I know GAE is fully secured environment and google take security very seriously, I would like to know 1. Any firewall running? 2. Do you provide any safeguards to prevent the user's credentials from being captured by a spyware? 3. Incase of the system failure how fast we are notified... If you can share some informartion, it will be great. Thanks in Advance. On 9/16/09, Jason (Google) apija...@google.com wrote: This can mean several things, so you'll have to be more specific.
