[appengine-java] Re: Which java framework to use?
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/. But the appengine-web.xml has "", 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:
http://permalink.gmane.org/gmane.comp.systems.google-appengine.jre/18014
This is fixed in "1.4.2 - 2011-02-16", look closely at the Location of
the App Engine SDK under Preferences -> Google -> App Engine and make
sure you don't have v201102111811.

[appengine-java] JSP compiling fails after upgrade from 1.3.8 to 1.4.0
I'm having issues using my GAE/GWT project after upgrading the GAE Java SDK from 1.3.8 to 1.4.0. It has issues compiling the JSPs, according to the error output. I've attached the stack trace. If I revert back to using 1.3.8, it compiles fine. (I'm using the Eclipse plugins.) It's entirely possible that this is a configuration error on my part, and that it just happens to work with 1.3.8, but I really don't know where to start debugging this. The answers I've found on the web so far are not GAE-specific, and point to classpath or read/write permissions issues. Because this is working with 1.3.8, I don't think either of those are my problem. Let me know if more information would be helpful. I'll continue using 1.3.8 for now. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: JDO update only happens if Entity is 'accessed' before makePersistent
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] JDO update only happens if Entity is 'accessed' before makePersistent
Hello.
I have a strange issue where I occasionally fail to update the Account
object in this method.
If I call the isEnabled() method (which returns true or false) before
I call makePersistent, the update always happens.
But if I don't 'access' the account object before makePersistent(),
the update doesn't happen.
I have no idea why this happens.
public final boolean enableAccount(final String key)
{
PersistenceManager pm =
PersistenceManagerFactoryUtils.getPersistenceManager(pmf, true);
pm.setDetachAllOnCommit(true);
final Query query = pm.newQuery(Account.class);
query.setFilter("enableKey == enableKeyP");
query.declareParameters("String enableKeyP");
try
{
List results = (List)
query.execute(key);
if (results.iterator().hasNext())
{
for (Account account : results)
{
if(!account.isEnabled())
{
account.setEnabled(true);
pm.makePersistent(account);
pm.close();
}
}
}
else
{
return false;
}
}
catch (Exception e)
{
LOGGER.warn("enableAccount() problem", e);
return false;
}
return true;
}

[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?

Yes Guillaume, We're looking into that, as well as some of the recent outages such as Farmigo (that seems to be back up now).

Hi Daniel,
For a possible workaround, have you tried manually coding the

For example, instead of:

[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.

[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.

[appengine-java] Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects.
Hi, I've got a strange problem with (I believe) my servlet mapping. I'm trying to map all requests for "/mountain/*" to a JSP file called "mountain.jsp". It works fine when I run it on my localhost, but when I upload the project to AppEngine, I get errors like the following: /mountain/5429370/index.html/index.html/index.html/index.html/ index.html/index.html/index.html/index.html/...etc The "/index.html" is repeated over and over until Chrome gives me the following error: "Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects." Chrome suggests clearing the cookies for the site, but I there are no cookies to clear. Here is my web.xml: http://java.sun.com/dtd/web-app_2_3.dtd";> mountain mountain.jsp mountain /mountain/* PeakPeekSite.html Has anyone seen this problem or understand what is going on?

[appengine-java] Compiling JSP with gdata: java.lang.NoClassDefFoundError: com/google/gdata/data/DateTime
Hi,
I've run through the example StockWatcher app, now attempting to
extend it by turning it into a JSP to add some server side
functionality with the java gdata client library. I can add a simple
appengine User service based piece of code and even create a URL
object:
<%@ page import="com.google.appengine.api.users.User" %>
<%@ page import="com.google.appengine.api.users.UserService" %>
<%@ page import="com.google.appengine.api.users.UserServiceFactory" %>
<%@ page import="java.net.URL" %>
...
<%
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user != null) {
%>
Hello, <%= user.getNickname() %>! (You can
sign out.)
<%
}
URL feedUrl = new URL("http://www.google.com/calendar/feed/
@group.calendar.google.com/public/full");
%>
However, when I go to add something from gdata, say something simple
like:
<%@ page import="com.google.gdata.data.DateTime" %>
...
DateTime foo = new DateTime();
I get the exception below in runtime. The jar files are in the build
path (I can build a straight-up java file with the gdata classes), and
it seems to find the DateTime class file during compile (if I remove
the import, I get a compile error). Is this some sort of runtime
thing? I am using gdata 2.0, jvm 1.5, appengine 1.3.

[appengine-java] Re: Session problem
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 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.. > > I filed a Bug report... > > http://code.google.com/p/googleappengine/issues/detail?id=2606 > > java.lang.RuntimeException: java.io.NotSerializableException: > com.google.apphosting.utils.jetty.AppEngineWebAppContext > $AppEngineServletContext > at > com.google.apphosting.runtime.jetty.SessionManager.serialize > (SessionManager.java:361) > at > com.google.apphosting.runtime.jetty.SessionManager.createEntityForSession > (SessionManager.java:341) > at > com.google.apphosting.runtime.jetty.SessionManager > $AppEngineSession.save(SessionManager.java:162) > at > com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter > (SaveSessionFilter.java:41) > at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter > (ServletHandler.java:1084) > at > com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter > (TransactionCleanupFilter.java:43) > at > org.mortbay.jetty.servlet.ServletHandler$CachedChain.doFilter > (ServletHandler.java:1084) > at org.mortbay.jetty.servlet.ServletHandler.handle > (ServletHandler.java:360) > at org.mortbay.jetty.security.SecurityHandler.handle > (SecurityHandler.java:216) > at org.mortbay.jetty.servlet.SessionHandler.handle > (SessionHandler.java:181) > at org.mortbay.jetty.handler.ContextHandler.handle > (ContextHandler.java:712) > at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java: > 405) > at > com.google.apphosting.runtime.jetty.AppVersionHandlerMap.handle > (AppVersionHandlerMap.java:238) > at org.mortbay.jetty.handler.HandlerWrapper.handle > (HandlerWrapper.java:139) > at org.mortbay.jetty.Server.handle(Server.java:313) > at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java: > 506) > at > org.mortbay.jetty.HttpConnection$RequestHandler.headerComplete > (HttpConnection.java:830) > at > com.google.apphosting.runtime.jetty.RpcRequestParser.parseAvailable > (RpcRequestParser.java:76) > at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:381) > at > com.google.apphosting.runtime.jetty.JettyServletEngineAdapter.serviceReques t > (JettyServletEngineAdapter.java:135) > at > com.google.apphosting.runtime.JavaRuntime.handleRequest > (JavaRuntime.java:235) > at > com.google.apphosting.base.RuntimePb$EvaluationRuntime > $6.handleBlockingRequest(RuntimePb.java:5235) > at > com.google.apphosting.base.RuntimePb$EvaluationRuntime > $6.handleBlockingRequest(RuntimePb.java:5233) > at > com.google.net.rpc.impl.BlockingApplicationHandler.handleRequest > (BlockingApplicationHandler.java:24) > at com.google.net.rpc.impl.RpcUtil.runRpcInApplication(RpcUtil.java: > 363) > at com.google.net.rpc.impl.Server$2.run(Server.java:838) > at > com.google.tracing.LocalTraceSpanRunnable.run > (LocalTraceSpanRunnable.java:56) > at > com.google.tracing.LocalTraceSpanBuilder.internalContinueSpan > (LocalTraceSpanBuilder.java:536) > at com.google.net.rpc.impl.Server.startRpc(Server.java:793) > at com.google.net.rpc.impl.Server.processRequest(Server.java:368) > at > com.google.net.rpc.impl.ServerConnection.messageReceived > (ServerConnection.java:448) > at com.google.net.rpc.impl.RpcConnection.parseMessages > (RpcConnection.java:319) > at com.google.net.rpc.impl.RpcConnection.dataReceived > (RpcConnection.java:290) > at com.google.net.async.Connection.handleReadEvent(Connection.java: > 466) > at > com.google.net.async.EventDispatcher.processNetworkEvents > (EventDispatcher.java:759) > at com.google.net.async.EventDispatcher.internalLoop > (EventDispatcher.java:205) > at com.google.net.async.EventDispatcher.loop(EventDispatcher.java: > 101) > at com.google.net.rpc.RpcService.runUntilServerShutdown > (RpcService.java:251) > at > com.google.apphosting.runtime.JavaRuntime$RpcRunnable.run &
[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..

[appengine-java] Re: Web based application in java.
Hi Yadav, I would recommend stepping through the "Getting Started" tutorial on the main docs pages for App Engine. In addition to providing some basic getting started info, you get to build a simple guestbook application that updates and queries data from the Datastore. http://code.google.com/appengine/docs/java/gettingstarted/introduction.html Hope this helps, -Chris On Jan 5, 1:22 am, yadav wrote: > Hi.. > I am trying to develop a small application in java on google apps.it > is mainly depends on data base.my question is how to create entities > and how to retrieve the data from it. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: Error while deploying GWT application on google app engine.
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] Creating an app with Fusion tables an Visualization
Hi App Engine community I am wanting to get some advice on an app I am looking to create. Basically the app is going to show analytics (google visualizations) to an authenticated user. These are the components that I am looking to employ. -send structured data from an external source into a google fusion table. -based on the user that logs in, query the data and display visualizations to them. Would fusion tables, GWT, GAE, Visualizations be the best components to use and are there any good code examples out there? I have stepped through a few other examples Stockwatcher example, gdata example, message board example, so have a basic grasp of the technologies Any thoughts? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

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'm probably just overlooking something, but according to the API documentation located here (http://code.google.com/appengine/docs/java/ javadoc/com/google/appengine/api/users/User.html) the User object should have a public getUserId method on it.

So your objects need to be mapped to the datastore somehow. I think of object/relational mappers performing that role even if it doesn't apply precisely in the case of a non-relational data store like Big Table. But I don't know if it's worth debating this point. I just want to know the best way to get up and running with a simple framework. Coming from the Ruby world, I'm used to have an ORM to translate my domain objects to relational structures in a way that I think is probably close to what Hibernate does.

I'm not familiar with JDO/JPA but since you make a point about there not being a need for an ORM, I will assume for now that these are some kind of data access objects that carry out the persistence operations for your domain layer.
