Hi,

Did you try "msg.setText(...);" to set message plain-text ?

[appengine-java] Re: Which one is best for development...Spring Framework or Servlet& Jsp....

[Thomas Wiradikusuma]

I'm also using Spring MVC and Spring Security.

I tried to ditch Spring in favor of Guice, but in the end I couldn't
live without it. Form handling, i18n, security, etc, everything make
me go back to Spring :) I use manual wiring, so performance is
acceptable. I no longer get timeout when first loading.

[appengine-java] Many /_ah/warmup - Deadline ExceededException

[Aswath Satrasala]

Hello,
My app-id has 'Always on' enabled
Our app-id activity has increased.  I am noticing 2-3 related issues.
* I am seeing many many "/_ah/warmup " in the logs.  (maybe our app-id
activity is increased)
* A lot of these are throwing 'DeadlineExceededException'.
* Why should that exception be thrown for some and not thrown for few
/_ah/warmup.

My logs are filled with above messages and errors.I feel something unusual
here.

  A serious problem was encountered with the process that handled
this request, causing it to exit. This is likely to cause a new
process to be used for the next request to your application. If you
see this message frequently, you may be throwing exceptions during the
initialization of your application. (Error code 104)

[appengine-java] Re: How to store these values in AppEngine Datastore using JDO

[Nick Rudnik]

You found the right article. Simply, you have to create a POJO with the 
proper annotations for the fields you want to persist, instatiate the POJO 
and set the properties with your two values, get a reference to the 
PersistenceManager and save the POJO.

[appengine-java] Two fields of sister classes in an entity!

[Muhammad Ijaz Khan]

Hi,
App engine doesnt allow yet, two fields of same class type as it says
"Class Card has multiple relationship fields of type Red: border1 and
border2.  This is not yet supported."
But can we use fields of different inherited classes from one parent? eg.
Card may have Red and Blue field types but both Red and Blue derived from
class Color.
Please update.
regards
Ijaz

[Simon Knott]

What storage mechanism are you using JPA or JDO?  I'm assuming that if 
you've got the error message for your Card object, that it would be a 
two-minute job to test the scenario you're querying about.

Simon

[appengine-java] Re: How to trace the TaskQueue status

[branflake2267]

I setup a JDO class and store the task attributes. I send back the JDO key 
and track it on the client side by polling it. I delete the entry after the 
task is finished. It works quite well for me.

[appengine-java] Timeout when trying to upload to Blobstore (files < 5k)

[Josh F.]

I'm trying to upload to the blobstore by programattically creating the POST 
request using the following class:

MultiPartFormOutputStream

 BlobstoreService blobstoreService = 
BlobstoreServiceFactory.getBlobstoreService();
 try
 {
 uploadURL = 
blobstoreService.createUploadUrl("/upload");
 }
 catch(BlobstoreFailureException e)
 {
resp.sendRedirect("close.jsp");
 }
 
 //add host if in dev mode
 if(uploadURL.indexOf("http") == -1)
 {
 uploadURL = "http://localhost:"; + uploadURL;
 }
 URL url = new URL(uploadURL);
 // create a boundary string

 String boundary = MultiPartFormOutputStream.createBoundary();
 URLConnection urlConn = 
MultiPartFormOutputStream.createConnection(url); 
 urlConn.setReadTimeout(3);
 urlConn.setConnectTimeout(3);
 urlConn.setRequestProperty("Accept", "*/*");
 urlConn.setRequestProperty("Content-Type", 
MultiPartFormOutputStream.getContentType(boundary));
 urlConn.setRequestProperty("Cookie", name + "=" + value);
 // set some other request headers...
 urlConn.setRequestProperty("Connection", "Keep-Alive");
 // no need to connect because getOutputStream() does it 

 MultiPartFormOutputStream out = null; 
try
{
 out = new MultiPartFormOutputStream(urlConn.getOutputStream(), 
boundary);
 // write a text field element
 out.writeField("old", oldBlobKey);
 out.writeField("topic", topic);
 out.writeField("category", category);
 out.writeField("key", key);
 // write bytes directly
 out.writeFile("myFile", "text/html", "content.html", htmlData);
 out.close();
}
catch(IOException e)
{
resp.sendRedirect("close.jsp");
}

Even when it times out  uploading and an exception gets thrown, the byte 
array still gets uploaded and the content.html file gets updated...I'm now 
sure how that works. I tried catching the exception with the above code, but 
sometimes it STILL displays an erro rmessage saying there was an uncaught 
IOException.

1.) Why is app-engine timing out when  uploading a file that is <5k in size?
2.) Why is it that even when I am attempting to catch the exception after 
creating the connection to the upload URL (in the case of the timeout), it 
still comes back as an uncaught exception...

Any help would be greatly appreciated! I really need to figure out why this 
Timeout is occurringI see people who talk about uploading files 
>1MB...how is it that my tiny HTML files timeout when being uploaded to the 
Blobstore?

[appengine-java] trying to import FileServiceFactory

[Josh F.]

I'm trying to do something like the code example for "Writing file to 
Blobstore", however I can't seem to import the FileServiceFactory class.

http://code.google.com/appengine/docs/java/blobstore/overview.html#Writing_Files_to_the_Blobstore

The API documentation says it's under 
com.google.appengine.api.files.FileServiceFactory; but eclipse can't find 
it.

[appengine-java] Session and load balancing

[hadf]

I would like to know if GAE insures that requests attached to the same
HttpSession are redirected on the same server instance, considering
that it may not because of load balancing.

[appengine-java] Re: Many /_ah/warmup - Deadline ExceededException

[Nischal]

When a new instance is spun, it gets the same 30 second limit that other 
http requests get on the appengine. You should see to it that your app loads 
up in under 30s. These errors are usually a result of the app taking more 
than 30s to load.

Re: [appengine-java] Two fields of sister classes in an entity!

[Bruno Fuster]

Using lists might solve your issue. If you assume item 0 is border1 and item
1 is border2, you could even create methods like getBorder1(return
list.get(0)) and getBorder2(list.get(1))

[appengine-java] Re: Cheapest way to update a versioned object?

[blue]

Thanks for the responses.

I'm using Objectify, but am bypassing it to write only to memcache.  I can 
definitely write-through, but that would mean I have datastore writes on 
every request, which is what I'm trying to avoid.

Does anyone know where the virtual ceiling is for memcache?  I would really 
like to sweep my memcache every 5 minutes and write to the datastore, but if 
I have a million users storing 1mb objects in memcache, are some going to be 
falling off the LRU cliff?

>From all the docs I've read and research I've done on GAE memcache, it seems 
that I shouldn't have to worry so much about losing anything in memcache if 
I'm doing a sweep every 5 minutes.  I guess I could write up some tests, but 
I'd like to know if anyone has any hard evidence as to if my objects are 
going to be evicted if I attempt this?

Thanks everyone!

Re: [appengine-java] Session and load balancing

[Nick Rudnik]

Why would this be needed? The session implementation stores its data outside 
of a specific jvm so every instance has access to all sessions. It is a very 
excellent design decision not to have to connect a user to a single instance 
for the life of a session. Instances can come and go as they please without 
affecting any existing sessions.

It will only clear when the execution succeeds. Check your log to see why it 
failed. Make sure your cron job actually returns a clean response with the

[appengine-java] is the remoteapi classes available in Maven repository?

[mingfai]

hi, a quick question, does anyone know if the following two classes are 
available in any jar/artifact in the Maven repository?
import com.google.appengine.tools.remoteapi.RemoteApiInstaller;
import com.google.appengine.tools.remoteapi.RemoteApiOptions;

I think I tried every artifact and checked the jars quickly and do not seem 
to be able to find these two classes.

[appengine-java] Re: Session and load balancing

[hadf]

This is not needed and we can manage with session store, but
developpers must be informed not to use static attributes, given that
they are shared between server instances. If not, developments that
works locally may not in production context.

[appengine-java] Re: why two regsitered caches share same space

[Stefan]

Hi Ikai,

could you please elaborate on this. Specifically, how do you use the
namespaces api in a local TESTING environment, i.e. using
LocalServiceTestHelper etc.? (It works fine in production and dev
server.)

When I call NamespaceManager.set("testing") in my test setUp() method,
this results in a NullpointerException in NamespaceManager.set().

Here is my setUp() method:

NamespaceManager.set("testing");
memcacheService = new LocalServiceTestHelper(new
LocalMemcacheServiceTestConfig());
memcacheService.setUp();

Please advice.

Best regards,
Stefan
