[appengine-java] Re: Request for best practice ideas for deployment of GWT JARs in AppEngine project
Hi Daniel.
That makes sense when internally you create Jars for modules to use in
multiple projects.
We are not using doing that. We inherit sub-modules in different ("top-
level") modules that we GWT compile.
So the Javac/GWT compile takes care of all that putting the .class
files into /war/WEB-INF and the JavaScript files into /war/module
name.
The problem is the third-party GWT library jars we are using. I'm
looking at them now, and many of them (gwt-maps, gwt-visualizations,
etc) will be client side only, others may have server code in them
(need to be very generic server side code to be included in a GWT
library jar)
So, I guess I'll have to split into three types of jars
- server side only jar -> normal case, nothing to do with
GWT. Just copy to /war and deploy
- GWT client side only -> I could not include these in /war at
all
- GWT server+client code -> Need to split them up somehow (if any
exist)

[appengine-java] Request for best practice ideas for deployment of GWT JARs in AppEngine project
We use GWT in our GAE project for UI stuff, plus RPC to back-end. In GWT you can use third party packages/modules that are packaged into .jar files, and can include Java source for server side, client side Java source (which is used during the GWT compile cycle to produce javascript), native javascripts, image files, css, etc.. We have these GWT jar files in our /lib directory and reference them from our class path, and our external ant build and Eclipse (with GWT plugin) are quite happy with all that. The GWT modules get compile, which generates the compiled javascript and files in the module's 'public' directory (images, css, etc) in / war. So far, so good. If a module has server side code (such as server side of an RPC the client code does, etc), then these .class files must be deployed to the server. Until now we were copying these .jar to our /war/WEB-INF/lib/ for deployment. But I have just realized a few problems with unecessary deployment of files due to that approach: - if a gwt jar (say, gwt-maps.jar) comes with source files (even Javadoc could be in there!) then we will also be deploying that - the client-side java .class files in a library .jar (used to generate javascript) will also be deployed, but never used on the server. I am not sure if that will make our app start-up slowed in AppEngine, or not. Either way, not too nice. What are other people doing in their build/deploy of GAE apps using GWT to avoid such things? -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Creating and Retrieving a blobstore file
Hi,
I'm trying to save a file to the blobstore similar to what is
described in docs at this page:
http://code.google.com/appengine/docs/java/blobstore/overview.html#Writing_Files_to_the_Blobstore
My code to write the file is:
// Create a new Blob file with mime-type "text/html"
AppEngineFile file =
fileService.createNewBlobFile("text/html");
// Open a channel to write to it
boolean lock = true;
writeChannel = fileService.openWriteChannel(file, lock);
PrintWriter out = new
PrintWriter(Channels.newWriter(writeChannel,
"UTF8"));
out.print(htmlText);
// Close without finalizing and save the file path for
writing
later
out.close();
filePath = file.getFullPath();
writeChannel.closeFinally();
I then save the filePath as a field on one of my Datastore entities.
However when I try and read it back, the following code falls into the
catch for FileNotFound exception:
public String fetchHtml(String remoteUrl) {
StringBuilder sb = new StringBuilder();
String returnString = null;
FileService fileService = FileServiceFactory.getFileService();
FixtureEntity fixture = getRecordByRemoteUrl(remoteUrl);
String fileName = fixture.getFileName();
AppEngineFile file = new AppEngineFile(fileName);
FileReadChannel readChannel;
try {
readChannel = fileService.openReadChannel(file, false);
BufferedReader reader = new
BufferedReader(Channels.newReader(
readChannel, "UTF8"));
String inputLine;
while ((inputLine = reader.readLine()) != null) {
sb.append(inputLine);
}
// line = "The woods are lovely dark and deep."
readChannel.close();
returnString = sb.toString();
} catch (FileNotFoundException e) {
logger.warning(e.getMessage());
} catch (LockException e) {
logger.warning(e.getMessage());
} catch (IOException e) {
logger.warning(e.getMessage());
}
return returnString;
}
I'm working on the dev server, with SDK v1.6.1. If I look in the
Datastore Viewer, the fileName is set on my entity to /blobstore/
writable:4IoqzMo2yJHJ7336lvNABg. There are __BlobInfo__ entities, but
all their "filename" properties are null.
If I do this:
FileService fileService = FileServiceFactory.getFileService();
BlobKey key = fileService.getBlobKey(file);
if (key == null) {
Thread.sleep(2000);
key = fileService.getBlobKey(file);
}
Key definitely gets populated. So I'm not sure why
readChannel = fileService.openReadChannel(file, false);
isn't working.
Can anyone see anything obviously wrong with my code? Or have any
suggestions as to how to get things working?
Many thanks in advance,
Andrew.

[appengine-java] Re: problem with Content-type: null with css files
A FYI about alternating versions for deployment to production... Our build script names the version according data from SVN (GIT would be similar), as a working copy (name = data and time), revision (name=r123), or tag (name = tag name = our release version number). Then the uploaded versions in appengine Dashboard all show either with their release number (or revision, or date). You can have up to 10 of them uploaded in production, working against production data - but just one as the 'default'... On doing a new release/deploy to production (after previously testing on another appid in integration and qa), we test the basics via the specific version urlif everything looks fine we then make the new version the default. If something goes wrong, you can quickly sqitch back to any of the previous 9 releases you have made, usually the penultimate one off course. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] Re: How to Limit/Slow Down Task Queue Execution
You might want to look into the algorithm for scheduling workers, as mentioned here http://code.google.com/appengine/docs/java/config/queue.html#Queue_Definitions (push queues only) Task queues use a "token bucket" algorithm for dequeueing tasks. The bucket size limits how fast the queue is processed when many tasks are in the queue and the rate is high. This allows you to have a high rate so processing starts shortly after a task is enqueued, but still limit resource usage when many tasks are enqueued in a short period of time. If no is specified for a queue, the default value is 5. For more information on the algorithm, see the Wikipedia article on token buckets. which links to this Wikipedia article http://en.wikipedia.org/wiki/Token_Bucket Haven't studied it yet, but your 100 bucket size might be influencing things. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

The problem with a cron every 30 seconds is that it will fire, and start up instances if you have none running - or extra instances if you have one busy - even where there is no "work" to be done. Maybe you have this non-time-critical work to be done once a day (as is my case also) and you don't care if it takes an hour or more, just want to crunch away at it in the background until it's done and then stop.

[appengine-java] Servlet Mapping not working as expected
I'm trying to get Velocity up and running with GAE, and the first problem I'm bumping into is that servlet mapping doesn't seem to be working as I'd expect. I've cut down the Web.xml to its bare minimum: velocity org.apache.velocity.tools.view.VelocityViewServlet velocity *.vm index.vm Now, when I access http://localhost:/ it presents with me with a page that looks as I'd expect (give or take). But when I access http://localhost:/index.vm it shows me the source of the page, rather than the processed version. With "*.vm" in the url-pattern, I'd have expected it to work exactly the same in both cases. I did a bit of further testing, rerouting things to my own servlet to see when it got called and when it didn't. If I use a uri to a file that exists then I get the source of it. If I use a uri for a file that doesn't exist (i.e. http://localhost:/DoesntExist.vm) then my servlet is called. Any suggestions as to why it would be getting the file directly rather than calling the servlet? Is there a setting I need to configure to tell it to call the servlet even if the file exists?

[appengine-java] Re: JPA/JDO vs low level API
I couldn't agree more with Jeff. JDO/JPA on GAE is pants for any real project. I am part of a 4 person development team that recently completed a fairly hefty 6 month GAE project built using GAE, GWT and Guice. We used JDO/Datanucleus for the persistence technology which caused significant problems across the project. As well as the issues that Jeff points out, simple things like IDE integration (predominantly Eclipse) with Datanucleus never seemed to work very well. Getting transaction demarcation to work with how the store 'actually' works is also practically impossible. We burnt a lot of days getting around a mass of silly little issues for no real benefit. To be clear, in standard relational environments we'll use Hibernate (et al) almost exclusively as an ORM, but, in my view, trying to use JDO/JPA on GAE is at this point in time a frivolous exercise that ultimately will heavily limit what you can do on the platform (not discounting the great work done be those that did port the standard over). It also lures you into this familiar relational way of looking at persistence problems which really does not, in any way, translate to how the datastore actually works. I'd be very interested to know how Google's internal projects work with the store -- as presumably, it's going to be a fairly similar interface -- but, if we were starting from scratch, I'd lobby very hard for using the low-level API on its lonesome (it's already a pretty clean service).

[appengine-java] Can you add Handlers to the root logger?
Hello, We're trying to add a handler to the root logger, which seems to work in dev, but, doesn't work in live. Our specific use case is that we are trying to add a Handler to facilitate sending log messages of a particular level to a remote log aggregation service. Has anyone had success in adding a handler to the root logger? If so, could you please detail your experience. We have tried things like: * Adding directly to the root logger through static initialization in Guice. This works in dev but gets a security exception (LoggingPermission) in live. * Various combinations of AOP. * Using logging.properties to explicitly define the logger. This was the most promising lead and actually seemed to be working, but, ultimately suffered the same problematic fate. We're currently exploring mitigation options like a logging facade (SLF4J or possibly just subclassing Logger), but, this has a host of obvious problems (no support for 3rd party libraries etc). Another option is to potentially try and use the admin logging console. If pertinent our app stack is GWT on Guice. Also, if we're lucky enough to have someone from the Google GAE team look at this it would be terrific to understand a little bit about the technical detail of logging for java in GAE. There is a reasonable amount of conflicting information around the web which has resulted in a lot of burnt time. An authoritative view would be very helpful and of obvious benefit when trying to design these types of solutions.

[appengine-java] Checking admin priviledges using UserService in a cron/task-queue task execution
I am trying to debug some issues with task execution and have a
question.
Background
==
Documentation states that tasks (cron and task queue) are executed by
a system process with admin priviledges.
To protect task execution from unauthorized execution I originally
protected them with a security constraint in the web.xml file. That
seemed to work OK.
Now, for other reasons, I'd like to protect them with code of my own
in a filter.
I have been trying to confirm admin priviledges in the filter, using
code like this:
public boolean isAdmin() {
UserService user = UserServiceFactory.getUserService();
if ( user.isUserLoggedIn() ) {
return user.isUserAdmin();
}
else {
return false;
}
}
and I also tried directly:
return user.isUserAdmin();
without checking for login first.
Problem
===
In both cases this seems to return false, even when when the request
comes from the system to run a task-queue task.
Despite the statement that these requests are run as admin.
Question:
===
Can I use the UserService to check admin permissions when the code is
being run in a request started by the system to serve a cron or task-
queue task?
thanks!

The problem is the URL returned by the call:

it returns

which is then NOT served.

[appengine-java] Re: Is programmatic access to cron jobs possible?
thanks for the replies. BTW: Didier, your code helps me fix the path differences for JUnit inside Eclipse which also bugged me! :-) For what I want to do I need to be able to delete a scheduled cron task Why? The idea was for a workaround for the "Can I detect a new deployment?" question I asked a few months back The idea was that the app would have a cron.xml that schedules a task every (say) one minute. After app deployment, the task would run almost immediately (which in itself implies a new deployment), do my "new deployment" activity, and then delete itself so it would not run again until the next deployment. On any subsequent deployment, the task would still be in the cron.xml and so would be rescheduled and it would all happen again. But it avoids a task running every minute checking a file or something. IKAI: I'm not sure I get your proposal if it could be done with that?

I wanted to have a servlet/task/cron be able to read the list of scheduled cron jobs and to disable/delete one so that it is no longer run in the future. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

[appengine-java] ImageService from dev server
I am having issues getting a url for an image to be served from the
ImageService when running locally on the dev server.
The code (which works fine when deployed) is this:
ImagesService imagesService =
ImagesServiceFactory.getImagesService();
String imageLocation = imagesService.getServingUrl(blobKey);
When running on the dev server locally (with a server URL of http://127.0.0.1)
the ImageService returns a URL of:
http://0.0.0.0:80/_ah/img/{key}
I also see that in the local dashboard there is no blobviewer.
Should I take this to mean that there is no image serving of blobs
when running on the dev server?
If so, it makes debugging more painful...
thanks

[appengine-java] No Billing -> No Blobstore
I am developing an app and have been working WELL within all development quotas for a while now (almost all of them show 0%). I recently coded image upload and use of blobstore for image storage, only to find that when attempting to deploy to production I get the following run-time exception: com.google.apphosting.api.ApiProxy$FeatureNotEnabledException: The Blobstore API will be enabled for this application once billing has been enabled in the admin console. at com.google.gwt.user.server.rpc.RPC.encodeResponseForFailure(RPC.java: 378) at com.google.gwt.user.server.rpc.RPC.invokeAndEncodeResponse(RPC.java: 581) ... So, I understand that there is NO Blobstore for free within development quotas? If I enable billing, will I be charged for Blobstore API use ONLY with other in-quote usage remaining free, or will billing be switched on for everything? The message seems clear, but it's a major hurdle for us, and so I just want to make sure I've got it right. This might be the trigger for me to investigate S3 and EC2....

[appengine-java] Bulk uploader not working reliably
Hi all,
I've been struggling to get the Python bulk uploader working reliably
with my Java GAE app.
My bulkuploader.yaml is correct (I think) yet sometimes when I'm
partway through uploading a CSV file the uploader barfs with the error
shown at the bottom of this post. The log viewer in GAE shows the
warning "com.google.apphosting.api.DeadlineExceededException: This
request (a5a74b909963ecc7) started at 2010/11/15 16:28:41.971 UTC and
was still executing at 2010/11/15 16:29:11.422 UTC." - I'm not sure
this is relevant though.
My CSV file is 500,000 lines. I split it up into 15,000-line files but
it's hit and miss as to whether those smaller files upload. I reduced
the number of worker threads, bandwidth limit, batch size, etc, but
that didn't seem to make the uploader more reliable.
I guess I could change my app to use app-assigned IDs for keys so I
don't get duplicate entities when I re-upload a file that's failed
partway through, but it'd be great to know why the bulk uploader
doesn't work out of the box.
Is anyone else having this problem and is there a simple solution or
workaround?
Thanks in advance
Andrew.

[appengine-java] Re: GAE or EC2
Hi Muhammad, here is a quick response: - read the datanucleus documentation on JDO for a general background - read the Datastore, Queries, Indexes and Relationships documentation from App Engine (we use Java API) for the set of restrictions they place on using JDO with the GAE datastore. - avoid using GAE specific types and APIs (e.g. Don't use "Key", use "Long", etc). That is what leads to most of the restrictions on what you can and can't do with JDO on datastore. such as having both Parent and child persistent objects with Long keys...etc - I expect that JDO on MySql has some restrictions also. I am not familiar with them, but our developer ran into a few of them. - we are looking at using namespaces for the datastore, and might create an emulation of it on MySql to keep our application code portable... >From that you get a kind of sub-set of what can and can´t be done with JDO on GAE/MySql, and leads to you having to manage child object storage via keys manually. Then off course, set up your project to be able to be built and ran on Tomcat/MySQL with little extra effort, and test on that other platform regularly and as part of your test and release process. It IS extra work, no doubt about that, even after the initial learning and experimenting. More coding, and more testing If there was a common place to share experiences in these attempts at portability (e.g. a wiki?) then we'd be happy to contribute to it, and learn from it... not sure to what extend Google (with it´s cloud portability goals) would be willing to host/contrinbute to that -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Solved, and my (obvious) error The task worker was being invoked with the (default it seems) POST method, but I had only implemented GET. The Dashboard log showed the servlet being invoked with no error and no output, but in fact it was trying to do the POST with no post doPost() method implemented. Although an obvious error on my part, maybe some error logging on the Dashboard for dummies like me in this case might be a good idea - when the required method needed to invoke doesn't exist.

[appengine-java] ManyToMany with list properties - IllegalArgumentException: name: String properties must be 500 characters or less.
Hi, I have a problem that I have a model where there are two hierarchys A---*B---*C D---*E---*F (---* = one to many relationships) B has a Key with A as its parent etc So the keys grow to be fairly large Everything was working fine until I added the extra condition (a unidirectional many to many relationship) F*>*C The only way that worked for me was to store it as a Set however I believe I have hit a problem in that it seems that the maximum size for the persisted ListProperties is 500 characters. ( I am using JPA.) Is that correct? Has anyone a suggestion to get around this problem. The exception is as follows: java.lang.IllegalArgumentException: name: String properties must be 500 characters or less. Instead, use com.google.appengine.api.datastore.Text, which can store strings of any length. at com.google.appengine.api.datastore.DataTypeUtils.checkSupportedSingleValue(DataTypeUtils.java: 192) at com.google.appengine.api.datastore.DataTypeUtils.checkSupportedValue(DataTypeUtils.java: 157) at com.google.appengine.api.datastore.DataTypeUtils.checkSupportedValue(DataTypeUtils.java: 123) at com.google.appengine.api.datastore.Entity.setProperty(Entity.java: 280) I cant tell what the property is but my guess is that it is the ListProperty. however as it says "name" it could be the name attribute from the MappedSuperclass that all the classes A-F inherit from. It would be helpful for the error message to say what class and or object generates the problem! The name property should not be more than 500 characters. more like 50 at most. Any suggestions?

[appengine-java] Using multiple PersistenceManagerFactorys for multiple concurrent Transactions.
Hello, Can someone from the GAE team please confirm whether this would be possible? My specific use-case is that I have meta data in one entity group and instance data in another. Services, using nested transactions and different PersistenceManagerFactorys, could hopefully access both (as they would be different 'Transactions' and never refer to the same entity groups). I've run various tests that seem to indicate that this should be possible, but I'm now getting IllegalStateExceptions as it seems I have: "Attempted to deregister a transaction that is not currently registered". The only way I could really see that this would be possible is if there was some type of thread-local stack that explicitly prohibits this from happening (as the nested tx would close the parent). It's no big deal if it can't happen, but would certainly be great if it could.

[appengine-java] Enhancement: Mail traffic and management in Dashboard

[appengine-java] Re: Determine in runtime (Java) who deployed app
Our use case in general is: We plan to allow users to openly login (which creates their initial account) to our app using google account, google apps domain account or openid. We plan to allow some users to be given "super-user" permissions for the application instance. They in turn will be able to give other users super-user permissions for a given area of the app. How to start the process of allowing super-user permissions? i.e. who is the first super-user, or the root user who starts that process, but in a secure and controlled fashion (not just the first person to log-in!). Our idea was to have the application deployer be detected on first login to the application (via google account, open id or other) via their e-mail address and be give "first super-user" or "root" permissions. They can then convert other users to super-users and everything if off and running. Just becase a Google Apps Domain user is the admin for the domain doesn't necessarily mean they should be able to admin any/all deployed instances of the application in that domain Conversely, to allow someone to admin the app we'd prefer to NOT give them admin permissions for the whole Google Apps Domain This made us look for alternatives to just checking if the user is an admin using the Users API. We want to have the app deployed on multiple different application IDs, and on different Google App Domains, and to have control over who is the "root" user on each independently, without hard-coding user names and passwords into the code or config files, so that the same "war" could be deployed to multiple appID/domains without change. If there is another recommended way of doing this, or similar, then we'd be interested to hear more about ir (and especially see sample code in Java :-) ). thanks. -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

up. It just seemed to work incorrectly in this case.
I wondered if it was something to do with the freemarker modifications
that were made in order to get things running on GAE. Can anyway else
reproduce this?
I'm using GAE 1.3.4 with Struts 2.1.8 via the Eclipse Plugin.

[appengine-java] Re: Security restrictions may not be entirely emulated errors in Dev mode with Spring 3.0 on 1.3.4
Hi Bill, I can see what you mean now. I have actually jumped over to a Struts 2 app at the moment, and whenever I change Java code I need to stop the development server and restart it. Very painful. Is this just the way it is, or are we missing something? Regards, Andrew. On Jun 3, 10:32 am, Bill Milligan wrote: > If you've gotten past point 2, I'd love to see it.

[appengine-java] Re: Security restrictions may not be entirely emulated errors in Dev mode with Spring 3.0 on 1.3.4
Thank you very much Bill. The suggestion in point 1 worked a treat. To answer your other questions, I am using asm 2.1 and spring 3.0.2. My url pattern is: /* When I said that the app was actually running, I meant that even though there were those errors in the console, I was able to browse to the hello world file and it gave me the expected output so it appeared the errors actually hadn't stopped anything from working. If you would like me to send you my eclipse project in a zip file please let me know and I'm happy to do so. Best regards, Andrew.

[appengine-java] Security restrictions may not be entirely emulated errors in Dev mode with Spring 3.0 on 1.3.4
Hi, I'm trying to get spring 3.0 up and running as per the blog post at http://www.ardentlord.com/apps/blog/show/829881-spring-3-0-on-google-app-engine However I'm running into some issues when I try and start it up in Development (have not tried in production yet): The console is showing a stack of these messages: 02/06/2010 2:50:19 AM com.google.appengine.tools.development.agent.impl.Transformer transform SEVERE: Unable to instrument org.springframework.web.servlet.view.DefaultRequestToViewNameTranslator. Security restrictions may not be entirely emulated. java.lang.NoSuchMethodError: org.objectweb.asm.ClassWriter.(I)V However as far as I can tell the app is actually running. There was a thread in this group late last year that described a similar issue, and the suggested solution seemed to be to rename the plugin.jar file to plugin2.jar: http://groups.google.com.au/group/google-appengine-java/browse_thread/thread/5e34079b5b3d58a1/b6db94a2df4ea58c?lnk=gst&q=Security+restrictions+may+not+be+entirely+emulated.#b6db94a2df4ea58c However the posters seemed to be using macs. I am on Windows 7 (Eclipse Galileo with the Google Plugin) and cannot locate this file - does anyone have any advice on where I may find it?

[appengine-java] Using Spring Javaconfig on Google App Engine

[appengine-java] Re: Anyone successfully redirected "naked domain" to their "www" domain with NetworkSolutions?
I just setup a non-AppEngine server that redirects all non-www requests to the same URL but with "www." added on the front. The server is setup to do this for any request, not just my domains, so anyone can use it. You don't need to mess with CNAMEs, just point the A record for the base (naked/@) domain to 74.53.18.72. I had extra hosting that I wasn't using since I moved an app onto AppEngine.
