[appengine-java] Help needed : "found more than 100 URLMap entries in application configuration"

[mably]

I'm hitting the "Found more than 100 URLMap entries in application
configuration" limit.

What is strange is that I have only 82  definitions in my
web.xml (many servlets).

Is it possible to have it increased by someone at Google?  My app ID
is webwinewatch.

Any help will be greatly appreciated as I can't deploy my app anymore.

Thanx in advance.

[appengine-java] Re: Local datastore is empty after migrating to 1.3.1

[mably]

Same thing happened to me.

Got an empty local datastore after updating to 1.3.1.

Hopefully I didn't have much data in it.  But it might not be the case
for everybody.

[appengine-java] Re: Generating QR Codes with ZXing

Hi Roberto, thanx for your answer.

I finally succeeded generating QRCodes with the ZXing QRCode encoder
and a home made PNGEncoder (derivated from the ones found there :
http://catcode.com/pngencoder/).

But I'm still stuck with Datamatrix bar codes coz ZXing doesn't
generate them.

Any help will be greatly appreciated.

More generally, has anybody heard of an open source barcode generator
java library running on GAE ?

We need to generate QR Codes or Datamatrix bar codes from our
application running on GAE.

We are using the Google Charts API for generating QR Codes for the
moment.

Thanx for you help.

[appengine-java] Re: Multipart mail regression in 1.2.8 ?

[mably]

Hi Ikai,

Effectively the code you provided seems to work but not exactly as I
hoped.

Before 1.2.8, I was able to send an html email with inline images
using the previous code.

Now the image is sent as an external attachment.

It's really sad we can't send nice html messages with images anymore.

Do you know if it will work again anytime soon ?

Thanx again for your help.

François

[appengine-java] Multipart mail regression in 1.2.8 ?

[mably]

This code doesn't work anymore for me :

public void test() throws Exception{

String from = "x...@gmail.com";
String to = "x...@gmail.com";
String subject = "Testing multipart email";
String htmlText = "Hello";
byte[] imgData = this.obtainByteData(
"/com/mably/cms/themes/standard/resources/images/
enveloppe.gif");

Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);

Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(from));
msg.addRecipient(Message.RecipientType.TO, new InternetAddress
(to));
msg.setSubject(subject);

Multipart mp = new MimeMultipart("related");

MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(htmlText, "text/html");
mp.addBodyPart(htmlPart);

MimeBodyPart attachment = new MimeBodyPart();
attachment.setFileName("test.gif");
attachment.setContent(imgData, "image/gif");
attachment.setHeader("Content-ID","");
mp.addBodyPart(attachment);

msg.setContent(mp);

Transport.send(msg);
}

What needs to be changed ?

Any help will be greatly appreciated.

[appengine-java] Re: HttpSession and setMaxInactiveInterval

[mably]

The session cookie is lost when you close your browser.

So no way to get back to the original session once you reconnect.

Nothing in common with an eventual authentication cookie.

By the way, do you know if Google plans to open source some parts of
GAE librairies so we could investigate deeper when we encounter such a
problem ?

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I haven't found a way to set a Content-ID header on a mimebodypart/
attachment using the low-level API.  The MailService.Attachment class
is quite rudimentary (only filename and data).

May be some part of the low level API are still undocumented ?

Thanx for all.

Of course, the code above doesn't need to be run in mail handler
servlet :-)

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I've written a simple class sending an HTML email with an embedded
image (cf. below) via GMail SMTP.  It works perfectly fine when run
locally from Eclipse.

The same code in a GAE mail servlet handler produce the infamous
"Converting attachment data failed" error.

So it really seems to be a problem in GAE javamail implementation.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

I'm just sending a simple mail from my Gmail account with an embedded
gif image.

I can perfectly read it from my mail servlet handler but when I try to
relay it (cf. code from first message) I get this annoying "Converting
attachment data failed" error which seems to be specific to GAE.

Here is the mail sent data :

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

In fact standards attachments works.

But it's not what I'm trying do do.

I'm need to relay HTML messages with inline images and this is still
not working.

Is it a kind of limitation of GAE or is it supposed to work ?

Thanx for your help.

Hi Ikai, have you been able to reproduce my "Converting attachment

I'm still stuck on this strange bug.

[appengine-java] Re: Can't send mail with attachment using JavaMail API

[mably]

Of course, here is below my email relay servlet class.  What I'm
willing to do is to hide my customers email addresses by relaying
email to them via my google app email adress.

I would like to be able to relay html emails with images which is
quite common nowadays.  I am sending my test emails from a gmail
account.

Thanx for your help.

[appengine-java] Can't send mail with attachment using JavaMail API

I keep getting this exception :

javax.mail.SendFailedException: Send failure
(javax.mail.MessagingException: Converting attachment data failed)

Seems related to issue :

Does anybody knows if there is fix or workaround available ?

Thanx for your help.

Thanx for your answer, the response times seems to be back to normal.
I'll keep an eye on it.

May be the two pages where served from different machines ?

[appengine-java] Re: PDF Generator Library

[mably]

Are you sure that JasperReports works fine on GAE ?

I thought it was using iText which doesn't seem to run on GAE (it
needs an unsupported patch).

[appengine-java] Datastore index deletion

[mably]

I tried to use appcfg command line with action "update_indexes" but it
doesn't delete my unnecessary indexes.

It seems there is no "vacuum" action like in the python version, am I
right ?

So, does anybody have another solution to delete a datastore index
with the java SDK ?

[appengine-java] Need GAE logs explanation

[mably]

Hello everybody,

I dont really understand the logs GAE shows me in the admin console :

I have a first URI showing a simple search form that gives me :

09-24 08:24AM 30.341 /default/ftsearch.do?_contenttype_=content 200
117ms 103cpu_ms 73api_cpu_ms

But my servlet service method lasts only :

INFO : com.mably.cms.web.DispatcherServlet service: 6ms

And I have a second URI listing data from the datastore that gives
me :

09-24 08:24AM 28.575 /default/notifications.do 200 38ms 27cpu_ms
13api_cpu_ms

INFO : com.mably.cms.web.DispatcherServlet service: 10ms

What's annoying me is that the fastest (6ms versus 10ms) servlet seems
to last longer for GAE (117ms vs 38ms) and to take more CPU.

Can somebody explain these numbers to me ?

Thanx in advance.
