[appengine-java] Re: Setting Namespace for an entire Request
According to the docs, the namespace is set globally within the app, but you can use it On a per-User Basis for users that are logged in as an example and that user is the tenant. The docs aren't clear, but the namespace must be globally just for that tenant, yes? If that's the case, then you wouldn't need to worry about concurrent access. You could make a quick test with 2 users and different namespaces... On May 13, 11:55 pm, Aswath Satrasala aswath.satras...@gmail.com wrote: Namespace-api is set normally in a Servlet Filter, which is normally the beginning point for most application HttpRequests. This means, there is a request coming in, it is serviced by a single-thread. Namespace-api is threadsafe and the namespace is put in the threadlocal, and hence, the same namespace is available during the complete HttpRequest serviced by that thread. -Aswath On Fri, May 13, 2011 at 9:13 PM, mpire sebastian.wennin...@googlemail.comwrote: Hi! I'm trying to use the Namespace-API to build a multi-tenant app. Therefore i have defined a filter that sets the Namespace for each request regarding to the User making the request. However, if there's a new Request before the current request finishes its datastore-operation, the namespace would be overwritten by the new request and the current operation would have an incorrect namespace. I could also set the namespace before each datastore operation, but the problem would be the same.If another request overwrites the namespace before the operation is finished, the data in the database will be messed. Is there a way to set the namespace for an entire request? Or should i try to build some kind of Mutex around the NamespaceManager?

[appengine-java] Re: How To: Persist an entity, if and only if, another successfully persists
I like Jeff's solution as it's failsafe, but one more pattern I often use is to set a couple of flags, and complete the 2nd action in a finally clause if needed. The timeout for the 30 sec limit does allow for a very quick transaction to still succeed, so I use that time to persist any state needed for the service I'm running, for example. On May 14, 4:09 pm, Jeff Schnitzer j...@infohazard.org wrote: Depending on your application, you may be able to perform the 2nd entity write in a task. Enqueue the task transactionally with the first operation. You'll be guaranteed that if the first entity commits, the 2nd will *eventually* be written as well.

[appengine-java] Re: App engine SDK jars in WEB-INF/lib. Why???
On May 13, 2:29 am, Nichole nichole.k...@gmail.com wrote: Just a quick summary, the servlet spec requires that a servlet container such as appengine provider an implementation for a service. Those jars such as servlet- api-2.4.jar are needed at compile time. That's why there's provided scope in Maven. They are sometimes provided by the servlet container/ engines at run time in a global directory that is found by the container/engine classloader. They have to always be provided by the container. E.g. the HttpServletRequest interface that the container classes implement and that you program against have to be the same class defined by the same classloader otherwise you get a LinkageError. appengine provides the servlet, jsp implementations for us at runtime. The appengine specific service implementations are also needed at runtime and compile time and are present in the appengine-api-1.0-sdk-ver.jar. They've chosen not to add the latest sdk to the container global classpath, so yes, the application must provide it. But that's silly. That means you deploy the local simulation implementations into production.

1. Allow the request to process normally, trapping any HTTP errors that

2. If no error was returned then do nothing, allowing the request to
complete successfully. If any error other than 404 was returned then send
the error through.

there is no file system in gae so

Re: [appengine-java] Re: how to transfer request to a different servlet ?
no, sorry :( . i want (kind of) server side redirect. you can think of a scenario where multiple applications are hosted in a single google appengine app but each app has to respond to its own unique domain. all the applications are handled by a master application. master application will accept all incoming requests, check the domain in the request and pass the request to the application the request is mapped to. for example: www.mydomain.com is mapped to MyHomeApp gallery.mydomain.com is mapped to MyGalleryApp test.mydomain.com is mapped to MyTestApp etc. all the apps have a main servlet (which you will map to /* in web.xml if you are not doing what i am trying to do), say HomeServlet, GalleryServlet and TestServlet. now if MasterServlet (mapped in web.xml to /*) receives a request which matches www.mydomain.com/*, it will pass that request to HomeSevlet; if it receives a request of type test.mydomain.com/*, it will pass the request to TestServlet. now here are my doubts : is it possible to transfer request from one servlet to another servlet ? MasterServlet to HomeServlet for example. is calling new HomeServlet().doGet() from MainServlet just fine (same as mapping HomeServlet to /* in web.xml) ? thanks.

Re: [appengine-java] Re: how to transfer request to a different servlet ?
Using Spring MVC you could use it to solve the problem. Basically you want different Controller for http://www.mainsite.com and http://test.mainsite.com I have used it in one of my application. I write all the steps in a blog here. I hope it will helpfull http://techsravi.blogspot.com/2011/05/managing-multiple-domain-and-sub-domain.html thanks, Ravi.

You should be able to use the RequestDispatcher object to do what you want but you'll have to have mappings in web.xml for each of the servlets your forwarding to for instance MyGalleryApp would have mappings that all start with /MyGalleryApp/ (or something similar) so GalleryServlet would map to something like /MyGalleryApp/GalleryServlet (or something similar) On Sun, May 15, 2011 at 7:51 AM, Prashant antsh...@gmail.com wrote:web thanks a lot Ravi. i will read your article and give it a try On Sun, May 15, 2011 at 8:20 PM, Ravi Sharma ping2r...@gmail.com wrote: Using Spring MVC you could use it to solve the problem.

[appengine-java] Re: Backends.xml ERROR when deploying
Dennis, You're half-way there :) GAE won't create a backend for you until you use the appcfg.sh 'update' command to update the backends. Check out the docs here: http://code.google.com/appengine/docs/java/backends/overview.html#Commands I also was really expecting the backends.xml file backends to show up in the admin UI - because all the other xml config files (cron.xml web.xml queue.xml) take effect as soon as you deploy. My guess is that the GAE team didn't intend it to be this way or that it's necessary to do that appcfg.sh step one reason or another. As soon as you get the backend running, you may have a hard time calling URLs on the backend. I got a not ready message a lot but that seems to go away after a little while. I'm having a hard time figuring out how to get the backend to run cron scheduled tasks. If you figure out a good way to do that, let me know.

Re: [appengine-java] Re: open source pdf engine for GAE
The code snippet is from the link I provided. Replace the attachmentData in the code snippet with the byte[] array returned from toByteArray(). You do not convert the ServletResponseOutputStream to a ByteArrayOutputStream. Create your own ByteArrayOuputStream.

[appengine-java] Vs: Re: Vs: Re: Stripes + UrlBinding + Google App Engine
Hello I did implement an empty mulitpart wrapper as I listed in my previous message so that was not the problem. Fortunately, I did solve my problem. The problem was not in the Stripes configuration at all. I had a following tag in my web.xml: jsp-config jsp-property-group url-pattern*.jsp/url-pattern include-prelude/jsp/include.jsp/include-prelude /jsp-property-group /jsp-config After removing it my app started working on the app engine as well. The app engine documentation (http://code.google.com/appengine/docs/java/config/webxml.html#web_xml_Features_Not_Supported) doesn't list this feature as unsupported. This threw me off a bit. But again, like so many time before, the problem lied in the configuration and the solution was found through relentless trial and error. Thanks for your help!

[appengine-java] Will requests from the same source typically be routed to the same GAE instance?
I'm planning to build a web service on GAE that I anticipate having to deal with significant amounts of load. I therefore want to make full use of memcache such that hopefully, most requests won't need to go to the datastore. There will be several different users of this web service, and each one is likely to require different, and not-overlapping data from the datastore. My hope is that GAE's load balancing will tend to send requests from the same user to the same Google App Engine instance, which will increase the memcache hit-rate. Is this how the load balancer works? Ian. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

Re: [appengine-java] Re: Backends.xml ERROR when deploying
Hi Jake, Can you give me the exact command you used? I'm not sure how to use appcfg.sh for the backend features. I'm actually planning to use the affcfg.py (which I believe is the same but just the python version) So what are the dir and [update] values supposed to be to make these backends.xml appear in the admin UI? My best guess is: appcfg.py ~/myapp/war/WEB-INF/appengine-web.xml backends update I dont think that's correct and want to know what you typed to get it to appear in the admin UI. Thanks! On Mon, May 16, 2011 at 3:29 AM, JakeP jake.pier...@gmail.com wrote: Dennis, You're half-way there :) GAE won't create a backend for you until you use the appcfg.sh 'update' command to update the backends. Check out the docs here: http://code.google.com/appengine/docs/java/backends/overview.html#Commands I also was really expecting the backends.xml file backends to show up in the admin UI - because all the other xml config files (cron.xml web.xml queue.xml) take effect as soon as you deploy. My guess is that the GAE team didn't intend it to be this way or that it's necessary to do that appcfg.sh step one reason or another. As soon as you get the backend running, you may have a hard time calling URLs on the backend. I got a not ready message a lot but that seems to go away after a little while. I'm having a hard time figuring out how to get the backend to run cron scheduled tasks. If you figure out a good way to do that, let me know.

They are sometimes provided by the servlet container/ engines at run time in a global directory that is found by the container/engine classloader. They have to always be provided by the container. E.g. the HttpServletRequest interface that the container classes implement and that you program against have to be the same class defined by the same classloader otherwise you get a LinkageError. appengine provides the servlet, jsp implementations for us at runtime. The appengine specific service implementations are also needed at runtime and compile time and are present in the appengine-api-1.0-sdk-ver.jar. They've chosen not to add the latest sdk to the container global classpath, so yes, the application must provide it. But that's silly. That means you deploy the local simulation implementations into production. No, appengine-api.jar is the definition of the App Engine API, with a convenient interface that wraps the running API implementation. In the case of the dev_appserver, the implementation is in appengine-local-runtime.jar (which you should not be uploading). In the case of production, the implementation is our production servers, running code you do not have access to.
