[appengine-java] OutOfMemoryError in appstats
Hi, Today after updating my application appstats started to throw OutOfMemoryError (see some stacktraces below). I had to remove appstats filter because this consumes too much cpu quotas. I found one note about OOME in appstats here: http://groups.google.com/group/google-appengine-java/browse_frm/thread/8cef51a7098584a7/740ad6145f1a628d?tvc=1q=appstats+outofmemoryerror#740ad6145f1a628d but there's no solution. So how can I fix this? - java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Unknown Source) at java.lang.AbstractStringBuilder.expandCapacity(Unknown Source) at java.lang.AbstractStringBuilder.append(Unknown Source) at java.lang.StringBuilder.append(Unknown Source) at java.lang.StringBuilder.append(Unknown Source) at java.lang.StringBuilder.append(Unknown Source) at com.google.appengine.repackaged.com.google.protobuf.TextFormat $TextGenerator.write(TextFormat.java:344) at com.google.appengine.repackaged.com.google.protobuf.TextFormat $TextGenerator.print(TextFormat.java:327) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printUnknownFields(TextFormat.java: 250) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printUnknownFields(TextFormat.java: 256) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.print(TextFormat.java: 47) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printToString(TextFormat.java: 73) at com.google.appengine.tools.appstats.Recorder.makeSummary(Recorder.java: 157) at com.google.appengine.tools.appstats.Recorder.makeSyncCall(Recorder.java: 216) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:98) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:48) at com.google.appengine.api.memcache.MemcacheServiceImpl.makeSyncCall(MemcacheServiceImpl.java: 179) at com.google.appengine.api.memcache.MemcacheServiceImpl.putAll(MemcacheServiceImpl.java: 460) at com.google.appengine.api.memcache.MemcacheServiceImpl.putAll(MemcacheServiceImpl.java: 499) at com.google.appengine.tools.appstats.MemcacheWriter.persist(MemcacheWriter.java: 264) at com.google.appengine.tools.appstats.MemcacheWriter.commit(MemcacheWriter.java: 177) at com.google.appengine.tools.appstats.AppstatsFilter.doFilter(AppstatsFilter.java: 94) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.ParseBlobUploadFilter.doFilter(ParseBlobUploadFilter.java: 97) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter(SaveSessionFilter.java: 35) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java: 43) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java: 388) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java: 216) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java: 182) --- java.lang.OutOfMemoryError: Java heap space at java.lang.AbstractStringBuilder.init(Unknown Source) at java.lang.StringBuilder.init(Unknown Source) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.escapeBytes(TextFormat.java: 1027) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printUnknownFields(TextFormat.java: 249) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printUnknownFields(TextFormat.java: 256) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.print(TextFormat.java: 47) at com.google.appengine.repackaged.com.google.protobuf.TextFormat.printToString(TextFormat.java: 73) at com.google.appengine.tools.appstats.Recorder.makeSummary(Recorder.java: 157) at com.google.appengine.tools.appstats.Recorder.makeSyncCall(Recorder.java: 216) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:98) at com.google.apphosting.api.ApiProxy.makeSyncCall(ApiProxy.java:48) at com.google.appengine.api.memcache.MemcacheServiceImpl.makeSyncCall(MemcacheServiceImpl.java: 179) at com.google.appengine.api.memcache.MemcacheServiceImpl.putAll(MemcacheServiceImpl.java: 460) at com.google.appengine.api.memcache.MemcacheServiceImpl.putAll(MemcacheServiceImpl.java: 499) at com.google.appengine.tools.appstats.MemcacheWriter.persist(MemcacheWriter.java: 264) at
[appengine-java] How to use OpenID on the GAE (with the GWT frontend)
I am doing a major rewrite of a working website. We have chosen GWT and GAE as the target architecture. I would like to complement our propriatory user authentication schema with OpenID. Hence, I was very happy that GAE supports the federated login. After spending the last 8 hours, I have failed to discover any useful artifacts that would make me understand how to use the User API in the federated mode. Additionally, I found out that the guestbook sample gets broken when switching the authentication option from the Google Account API to the Federated Login, causing the login page to be repeatedly called (shortly showing the CheckCookie URL inbetween). I guess this is not a planned behaviour, even thought the method used for obtaining the redirect URL is not forseen for the federated mode (createLoginURL vs createFederatedLoginURL). I would appreciate any comments and/or pointers on this topic as I am aiming on producing a set of basic demo applications using the most promising libraries. The findings will be published in the blog (super-easy.blogspot.com) with the hope that others won't need to waste so much time. I read lots of posts reffering to the dyuproject as a viable OpenID library for GAE and will use it as the next candidate.

[appengine-java] BlobstoreService serve method
Hi,
I'm using java in GAE and i recently started using Blobstore to serve
my application download file, the only issue that i have is that
when it serves the file, the size is not sent to the browser so it
can't estimate the time for the download to complete...
here is the piece of code that i use to serve the file:
BlobstoreService blobstoreService =
BlobstoreServiceFactory.getBlobstoreService();
IteratorBlobInfo iterator = new
BlobInfoFactory().queryBlobInfos();
while(iterator.hasNext()) {
BlobInfo b = iterator.next();
if (b.getFilename().equals('myfile.exe'))
blobstoreService.serve(b.getBlobKey(),resp);
}
is there a way to also send the file size to the browser while serving
the file?
thanks,
Oded.

[appengine-java] GfS and Struts
Hello i try integrated Google file service and Struts 1
i'm using lib: common-fileupload 1.2.1 and common-io 1.4
This is my Action:
--
codepublic class AddProductAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm
form, HttpServletRequest request, HttpServletResponse response)
throws Exception {
//private static final long serialVersionUID = 8367618433138027430L;
AddProductFormBean myForm= (AddProductFormBean) form;
String fileId = ;
String fileOwner = ;
int fileSize;
FormFile File = myForm.getUpFile();
String contentType = File.getContentType();
String fileName= File.getFileName();
fileOwner = myForm.getFileOwner();
fileId = myForm.getFileId();
InputStream stream = File.getInputStream();
stream.close();
fileSize = DatastoreUtils.insertGoogleFile(fileId, fileOwner,
fileName, contentType, stream);
return (mapping.findForward(success-addproduct));
}
}/code
-
And this is my FORM FILE:
public class AddProductFormBean extends ActionForm
{
private FormFile upfile;
private String fileOwner;
private String fileId;
public String getFileId() {
return fileId;
}
public void setFileId(String fileId) {
this.fileId = fileId;
}
public String getFileOwner() {
return fileOwner;
}

this.fileOwner = fileOwner;
}
public FormFile getUpFile() {
return upfile;
}
public void setUpFile(FormFile upFile) {
this.upfile = upFile;
}
}

[appengine-java] Mailservice - creating a conversation
Hello I'd like to send several mail messages so that they create a conversation in the recipient's mailbox. I assume this is accomplished by 'Message-ID', 'In-Reply-To' and maybe also 'References' headers. Unfortunately: For security purposes, the Mail service does not allow arbitrary headers on outgoing email messages. Some headers are overridden by the Mail service, such as the message send date. Other headers added to the outgoing message are stripped. http://code.google.com/appengine/docs/java/mail/usingjavamail.html#Messages_and_Headers Is there a chance GAE would white-list some headers and add their respective methods to Mailservice API?

[appengine-java] Re: IllegalArgumentException: ETA too far into the future
oops the bug was in my code instead of a delay or countdown, I was giving a time value, so the delay would have been something like 2010 years. I would still be curios to know what max eta is though.

[appengine-java] Restriction for URL fetch with the same URL
I'm trying to make my ajax site crawlable following: http://code.google.com/web/ajaxcrawling/docs/getting-started.html Basically, whenever I receive a request with _escaped_fragment_=..., I need to fetch the same page with HTMLunit, but without the _escaped_fragment_ part (and with a hash fragment). So, I got HTMLunit unit to run on GAE (with the fine patch by Amit Manjhi), and I'm able to fetch pages from all across the web and render them with it. I'm also able to use HTMLunit on another site to render my webapp. But whenever I try to use HTMLunit in my app to render my webapp, it seems to fail. I don't see anything helpful in the logs, but I suspect this has to do with the URL fetch service restriction that disallow fetching the same URL. Now, the URL is not exactly the same (I remove some parameter and add a hash fragment) but it's fairly similar. I was wondering: - Are the precise restrictions on using URL fetch on the incoming URL documented somewhere? - Is there any good workaround for the problem? - Or maybe my problem is something else altogether and you have an idea for me? Thanks a lot! Philippe -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

I've just checked my app against the new JDK. The bug is *somehow* fixed. Freemarker run fine now.

Hence, I was very happy that GAE supports the federated login. After spending the last 8 hours, I have failed to discover any useful artifacts that would make me understand how to use the User API in the federated mode. Additionally, I found out that the guestbook sample gets broken when switching the authentication option from the Google Account API to the Federated Login, causing the login page to be repeatedly called (shortly showing the CheckCookie URL inbetween). I guess this is not a planned behaviour, even thought the method used for obtaining the redirect URL is not forseen for the federated mode (createLoginURL vs createFederatedLoginURL). I would appreciate any comments and/or pointers on this topic as I am aiming on producing a set of basic demo applications using the most promising libraries. The findings will be published in the blog (super-easy.blogspot.com) with the hope that others won't need to waste so much time. I read lots of posts reffering to the dyuproject as a viable OpenID library for GAE and will use it as the next candidate.
