[appengine-java] Re: email in yahoo junk - amazon ses

2011-07-08 Thread pac

I was also trying to contact yahoo, they get back to me and asked me
to do few things but I don't have access to do those , may be some
body from google can do this i.e.

Thank you for writing to Yahoo! Mail.

To further troubleshoot the issue, please send a test email (from the
affected server/IP) via a telnet session to see if you can recreate
the
problem.

The URL below describes how you can do a manual telnet test. Please
telnet to this host "a.mx.mail.yahoo.com" (i.e., "telnet
a.mx.mail.yahoo.com 25").

http://www.spamsoap.com/how-to-manually-send-an-email-message-via-telnet-to-port-25

Once you've followed the steps, please send us the transcript of the
telnet session when you reply to this email.

For assistance with delivery issues to Yahoo! Mail, please visit:

  http://help.yahoo.com/l/us/yahoo/mail/postmaster/

Please let us know if you need any assistance, so we may assist you
further.

Your patience is greatly appreciated.

Thank you again for contacting Yahoo! Mail.

I think ip address in that email case was

X-Originating-IP: [209.85.216.205]

but I guess that could be any e.g.
74.125.79.27
74.125.53.27
209.85.143.27
74.125.43.27
72.14.213.27
209.85.229.27
74.125.157.27

[appengine-java] email in yahoo junk - amazon ses

2011-07-08 Thread pac

Is it possible to use amazon SES to send emails?
Emails sent by application are going in yahoo's junk folder.
My application hardly send few emails per day.

Just looking various posts:
http://code.google.com/appengine/forum/?place=topic%2Fgoogle-appengine%2FazhX_BKiNiE%2Fdiscussion
http://code.google.com/p/googleappengine/issues/detail?id=3161

It looks that people have used amazon SES with success.

But I am unable to make it work in java, on connect I get error

   Transport t = new AWSJavaMailTransport(session, null);
t.connect();

Caused by: java.lang.NoClassDefFoundError:
javax.net.ssl.KeyManagerFactory is a restricted class. Please see the
Google  App Engine developer's guide for more details.

In production log I see good few

Though I have code under try catch and handling Exception and printing

It was changing during transformation.

ProcessingInstruction pi =

rootElement.appendChild(pi);

fixed it.

Thanks for your response Brandon.

But in my case, file is served from blobstore i.e.

 blobstoreService.serve(blobKey, res);

So file serving is not an issue but angular brackets get changed which
I want to avoid i.e.

<   to  <
>   to  >

Are you suggesting, I should fetch data from blobstore and write it to
response?

[appengine-java] issue in serving xml file from blobstore

2011-04-27 Thread pac

I am creating xml file in blobstore but after serving from blobstore,
when saved through browser then

CDATA barckets get changed i.e



to

]]>

Thought elements brackets stay fine i.e.  remains as it is.

During file creation I use:

fileService.createNewBlobFile("text/xml",xmlFileType + ".xml");
new PrintWriter(Channels.newWriter(writeChannel, "UTF8"));

and when it is served then:

 res.setContentType("text/xml");
 res.setHeader("Content-Disposition","inline; filename=" + xmlFileType
+ ".xml");
//res.setHeader("Content-Disposition","attachment; filename=" +
xmlFileType + ".xml");
 blobstoreService.serve(blobKey, res);

Any suggestions to fix it?

Thanks.

[appengine-java] Re: gae gwt - to serve compressed java script

2011-03-24 Thread pac

Hi Didier,

Yes, I have looked into this.
It says if request has gzip then app engine will supply compressed
contents.

So in this case request does have gzip i.e.

Accept-Encoding: gzip,deflate


But it looks that it still does not send compressed data.

I am not sure what can I do to fix it.

Thanks.

[appengine-java] gae gwt - to serve compressed java script

2011-03-24 Thread pac

It looks that app engine is not serving compressed contents.
Is there something I need to configure? though it says that it does
that automatically

http://code.google.com/appengine/kb/general.html#compression

I have application written in gwt and java scripts are served
uncompressed from app engine as per Page Speed plugin of Chrome and
FireFox. It suggests to enable compression.

>From Page Speed:

Compressing ./4.cache.js could save 336.2KiB (77% reduction).



>From Live HTTP Headers plugin of Firefox:


./4.cache.js

May be I am wrong, but I am guessing that if app engine is serving
compressed contents then in its response it will say something like

Content-Encoding: gzip



May be I am missing something, any suggestions to fix it?

Thanks.

Hi Ikai,

If you could confirm this - from earlier Stephen's post:

"then I think you
will be safe even though it might take another minute or two for
Google's
infrastructure to stream it to the client. I have not tested this
though.
Can anyone confirm or deny this assumption on my part."

is download outside 30 sec limit i.e. after servlet finished in 30
seconds?

Thanks.

2010-11-29 Thread pac

Sorry, did not see your post earlier Stephen.

I was not aware of this 10 minute feature to create a file, I will
look into.

File size will be greater then 10MB, it is an existing website which I
am thinking to port to gae, file size already gets around 12MB or so.

So I guess more than 10MB download will be an issue and I guess
download should also complete in 30 second, is that so?

[appengine-java] Re: data in xml format from data store

2010-11-29 Thread pac

A client will download a xml file instead of uploading.
Records will be created (or updated, deleted) in a table/kind over
time and all records from a kind need to be downloaded in form of a
xml file, I hope I am explaining the issue bit more clearly.

I am not sure if I could make use of blobstore in this case as it will
require update of blobstore object (in background may be using task)
every time a record gets added/updated/deleted i.e. if I create xml
file programmaticaly and store as blobstore object.

[appengine-java] data in xml format from data store

2010-11-29 Thread pac

In a website I need to provide a feature to get data in xml format
i.e. some url

e.g.
http://www.mysite.com../data.xml

I think in gae I can not create a file. Any suggestions to create such
feature to get data from data store in this way?

Data store will have large number of records, so in general, a file
created from that could be of good few MBs.

[appengine-java] Re: blobstore - map returned empty

2010-10-31 Thread pac

I have gone through your sample code few times, could not find what I
am missing.
What I tried now - is created a dialog with simple file upload field
(rest functionality nearly copy pasted), now that seems to be working.
May be I will come back to other code and see what causing it.
Though another thing which I came across is that some time
ImageService ( String imageURL =
imagesService.getServingUrl(blobKey); ) returns serving url with ip
address i.e. instead
/_ah/img/iS_QaJQHwq-tmmA4_5i6kw

it returns

http://0.0.0.0:/_ah/img/iS_QaJQHwq-tmmA4_5i6kw

In such case image does not get display as incorrect local ip address
i.e. http://127.0.0.1:

[appengine-java] Re: blobstore - map returned empty

2010-10-27 Thread pac

Hi Ikai,

Upload page is a composite, in which I have a decorator panel which
contains another composite which has FormPanel (Upload field)

As for servlet code:


public void doPost(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
String userIdStr = req.getParameter(IAppConstants.PARAM_UserId);

Map blobs = 
blobstoreService.getUploadedBlobs(req);

BlobKey blobKey = blobs.get(IAppConstants.PARAM_MyFile);
.
.
.

blobs returned  is empty and so blobKey is null.

IAppConstants.PARAM_MyFile is name of upload field at client side
i.e.

uploadField.setName(IAppConstants.PARAM_MyFile);

In servlet if I do

String myFile = req.getParameter(IAppConstants.PARAM_MyFile);
then myFile is also null.

Upload form at client does have

uploadForm.setEncoding(FormPanel.ENCODING_MULTIPART);
uploadForm.setMethod(FormPanel.METHOD_POST);

Any suggestions?
Thanks.

Initially, I was thinking to use JDO but after finding all the posts
about slow start up, I decided to use Objectify and it is great.
Thanks to app engine team for such great platform, though I missed few
things especially search capability and limitation of querying on list
property due to index limitation, but still it is great and hopefully
in near future they will be implemented.
Thanks to all those people who take time to respond to questions in
forum and especially to Objectify’s Jeff who replied to all my silly

only query on ItemIndex and transform them to parent keys (http://
www.youtube.com/watch?v=AgaL6NGpkB8) and then filter in memory as per
invoiceDate? But this way I may end fetching lots of invoices which do
not meet criteria, any  suggestions?

class Invoice
{
@Id Long id;
Date invoiceDate;
Long invoiceNo;
}

class ItemIndex
{
@Id Long id;
@Parent Key invoice;
List items;
}
