My suggestion: For datastore access use Objectify: http://code.google.com/p/objectify-appengine/ For your MVC framework go with AJAX/Javascript/HTML5 and use Backbone.js: http://documentcloud.github.com/backbone/ We've used Tapestry5 on App Engine before but without lazy loading and serious optimization you can have 15 second cold starts. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Axis2 soap client implementation doesn't work
When I was researching WS clients for GAE, I found that Axis attempts to open
network sockets directly, rather than using HttpUrlConnection. That was a
while ago, perhaps a work-around has been found.
The AccessControlException you are getting could be a result of that.

[appengine-java] Need some help with GWT / GAE and serialization - I'm missing something
I have an app that uses GWT and GAE. I recently looked at it after not having done anything with it for a long time. Since the App Engine SDK and the GWT SDK had new versions since the last time I looked at it I upgraded to the latest: GAE 1.4.2 and GWT 2.2.0. I'm able to run the app locally in development mode and everything is good. But when I deploy it to App Engine and try to run it I'm getting an error saying: ERROR: The serialization policy file '/webtroopmanager/A5CAB72C510469B1D74BD9576D34BED3.gwt.rpc' was not found; did you forget to include it in this deployment? I don't understand where this file is supposed to come from in the App Engine environment. I've got it on my dev system in war/modulename. But the appengine-web.xml has exclude path=**.gwt.rpc /, which I think means it's not going to get deployed along with the app. I'm not clear on what the file is or what's in it, but the error messages suggest that it's supposed to be on the server and it isn't. How is it supposed to get there? Thanks for the help. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

If you are seeing this problem:

This is fixed in 1.4.2 - 2011-02-16, look closely at the Location of

HI All,
I found a very dirty workaround but at least it works for me.
I was not aware of the doNotValidateCertificate() API that Fred
mentioned.
I made a very small change (one line of code) to the SDK appengine-
api.jar.
I have decompiled com.google.appengine.api.urlfetch.HTTPRequest and
added the call to doNotValidateCertificate() on the FetchOptions in
the constructor:
public HTTPRequest(URL url, HTTPMethod method, FetchOptions
fetchOptions) {
payload = null;
this.url = url;
this.method = method;
this.fetchOptions = fetchOptions;
this.fetchOptions.doNotValidateCertificate(); \\ADDED BY ME
headers = new LinkedHashMap();
}
Then I repackaged the jar with my change and that solved the issue for
me - No certificate validation by default (Only on Dev server).
This way I don't have to change every piece of code that uses
URLFetchService with https and more important the production env still
makes sure the validation occurs.
Note that this solution will fix only flows where the URLFetchService
is used.
I do hope a better fix is provided by the App Engine team soon.
Thanx, Lior

In order to help me diagnose the problems, could you respond with what

FetchOptions (http://code.google.com/appengine/docs/java/javadoc/com/

Hi hari,
Yes, calling account.isEnabled() before makePersistent() seems to be
required for the update to happen, but I'm not sure how this relates
to the issue of lazy-loading you mentioned. This is a detachable
entity (pm.setDetachAllOnCommit(true) + annotation). Maybe that has
something to do with it?

[appengine-java] Execute CSS files as JSP
Hello, I need to dynamically generate CSS files and would like to do it with JSP. I know that there are various existing solutions to do this with servlets mapped to the .css extension and forwarding to JSPs to generate the content and that would technically work. However, I would like to maintain the css extension so that my IDE correctly loads the css editor with color coding and formatting. Ideally, I would like to map the css extension to the JSP servlet. I did this with the Google developer container in Eclipse (mapped .css - _ah_jsp servlet) and it worked fine. However, when I deployed the app to appengine, I got an error saying the _ah_jsp servlet did not exist. I expect this has to do with JSPs getting precompiled before the app is deployed to appengine. Is there anyway to get my CSS files to execute as JSPs or precompile as JSPs (while maintaining the css extension on my local filesystem for the IDE) for appengine?

[appengine-java] Re: JSF2 f:ajax does not work for me... Any Ideas Why?
Hi Daniel,
For a possible workaround, have you tried manually coding the
JavaScript for the Ajax request call?
For example, instead of:
h:commandButton
f:ajax render=foo/
/h:commandButton
... manually coding the JavaScript for the Ajax request call would be:
h:commandButton onclick=jsf.ajax.request(this,event,
{render:'foo'});return false;/
This was taken from:
http://andyschwartz.wordpress.com/2009/07/31/whats-new-in-jsf-2/#ajax-declarative
Also, is this the only JSF2 tag that you've encountered that does't
appear to be working in App Engine?

[appengine-java] Re: Need help choosing a frontend framework for a GAEj app, GWT seems like overkill
Hi Mike, I think the reason we don't explicitly publish a list of frontend frameworks that play well with App Engine is because there really is no technical barrier between front end frameworks that work in the browser such as JQuery, etc and the backend (App Engine). Many App Engine users make full use of a myriad of front end technologies/ frameworks for UI creation ranging from HTML5/JS/CSS to flash etc. JQuery is especially popular for a variety of Web app usages, so if that works for you, I'd definitely continue trying it out. Hope this helps, -Chris On Sep 9, 10:43 am, tempy fay...@gmail.com wrote: Hello all, A little background... I'm mostly new to web frontend development, I come from a mostly backend and desktop background. I have a GAEj app that provides the backend for a rather sophisticated desktop/mobile app. This backend will also drive a website in addition to the desktop/mobile app. The website will show a small subset of the data in the system. I started with GWT, but it doesn't seem to be quite right. The website is for presentation of a small subset of the system's data only, and users do not interact with the data in any way other than searching for it. As the data is mostly unstructured text and some images, I feel most comfortable formatting it with plain old html/css. In fact, the layout of the site will be minimal and look a lot like a blog. As such, the website should certainly not feel like a single-page web application a la gmail. With GWT, I have little use for widgets and find myself constantly fighting with it to get a non-application look- and-feel. The only functionality that I thus really need from GWT is the RPC component, the page should be AJAX, I don't want to do round trips to the server for every navigation event. So, I'm not quite sure which framework to use with the GAEj backend. At first GWT seemed like a natural fit, but now seems like overkill. I'm doing some research on jquery, but I haven't seen a list of frontend frameworks that play well on GAEj anywhere.

[appengine-java] Re: Applets in GAE
Applets should be fine as long as the applet jar file(s) are not too big. (10M) If they are bigger, you'll need to upload and deploy your app via the command line appcfg with option --enable_jar_splitting specified. For networking you should be able to send REST request from your applet to your server using standard Java networking. You could create a test servlet on the server to listen for your applet.

Hi Reena, It looks like you have a problem with your web.xml file. I believe I had a similar issue where I can run locally, even with a slightly invalid web.xml file. You might want to doublecheck that your war/WEB-INF/web.xml file is syntactically correct. If you're curious what a clean one looks like, you can always just create a new project using the Eclipse plugin, and generate a new app with both GWT and GAE checkboxes checked. You could then compare and contrast between the two.

[appengine-java] Re: One To Many. JDO. Error while save data.
Here's some ideas to try...
I see that you have a if statement in your JSP..
if(request.getContentLength() 0) {
...
Are you sure this condition is true in your case? Otherwise the JSP
will never attempt to save the object.
If that's not it, you could always create a new JSP and just drop the
exact servlet code into the page via a scriptlet and work backwards
from there.
Hope this helps..

Is the object you're trying to save onto the session serializable? Does it implement serializable? (although just making the class implement serializable will not always work) I believe that you can have a class bypass validation for this when running locally - so you may not be seeing the serialization error because of this. In any case, I would definitely make sure you can actually serialize the object that you're saving. -Chris On Jan 5, 7:41 am, avdhesh avdhesh.ya...@gmail.com wrote: I got following exception wehn i deploy a application to google apps engineEverything works fine with EclipsePlugin...May be EclipsePlugin not able to catch this..

[appengine-java] 5000 row query
Hi, I'm trying to return 5000 rows by using 5 sets of 1000. However the CPU utlization is really high. I need to get the full 5000 to work out a calculation based on the data. This prevents me from performing any paging operations. I don't need to display all the data at once but simply getting the rows is causing some issues. I don't want the high cpu utilization to cause the requests to timeout. Does anyone know of anything i could try?
