[appengine-java] Re: gae.encoded-pk not working on MySQL
Hi,
This is what I do/did. Sadly, my method requires commenting and
commenting out for each persistent entity class, but I could not get
pre-compilation directives to work (quickly), so I lost patience with
that approach.
Enjoy(?)
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = true)
public class Stuff implements Serializable
{
private static final long serialVersionUID = 1L;
//
// This block is required since this entity has an entity group
root.
// It does not work with MySQL, so we use an alternative for that
database.
// We have the getter method for getting the encoded key here for
convenience.

@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-pk,
value=true)
private String sEncodedKey;
@Persistent
@Extension(vendorName=datanucleus, key=gae.pk-id, value=true)

Hi all,
I'm experiencing some problems using gae.encoded-pk on MySQL.
Reading the documentation (http://code.google.com/intl/en/appengine/
docs/java/datastore/creatinggettinganddeletingdata.html) I found that:
Encoded string keys allow you to write your application in a portable
manner...
but I can't find any information on how to achieve this. Consider this
sample code from the docs:
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
@Extension(vendorName=datanucleus, key=gae.encoded-pk,
value=true)
private String encodedKey;
This will work on appengine, but if used on an alternative stack of
DataNucleus + MySQL, then it won't work (the automatic schema tool
ignored the extension, and attempts to create a varchar column with an
AUTO_INCREMENT attribute, which makes no sense).
Does anybody know how to achieve the desired behaviour?
Many thanks in advance!!

[appengine-java] Re: Restricting upload size to the blob store
I don't see anything in the docs about limiting the size of blobs that can be uploaded. My guess (if it's helpful) is you have to check the size after it's uploaded (via BlobInfo) and delete a blob that's too large and return an error to the user. I don't think there's any reliable http/html/browser standard that would limit the size of a file upload and handle the UI to alert the user, so it's seems fair that the blobstore gives the basic building blocks up a file upload and you have to add your limit and code/UI to handle files over the limit. If you're interested, I did find the following discussion about a JavaScript approach to check and limit file sizes for uploads, but apparently it doesn't work in all browsers http://forums.digitalpoint.com/showthread.php?t=1461121 -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Securing JSESSIONID cookie
Or a better question, since I don't actually want to use sessions: Why is the JSESSIONID cookie set even though sessions aren't enabled in appengine-web.xml, per http://code.google.com/appengine/docs/java/config/appconfig.html#Enabling%5FSessions You can get rid of it by adding %@ page session=false % to each JSP, so this is an academic question I guess.

[appengine-java] Issues with JavaMail
Hi,
I'm using the MailService feature of Google App Engine in my
application. It works fine in one application without any issues.
But the same code doesn't work in another app. I'm not able to figure
it out. Please help. Following is the piece of code that I use to
send mail.
public static void sendHTMLEmail(String from, String fromName, String
to,
String toName, String subject, String body) {
_logger.info(entering ...);
Properties props = new Properties();
Session session = Session.getDefaultInstance(props, null);
_logger.info(got mail session ...);
String htmlBody = body;
try {
Message msg = new MimeMessage(session);
_logger.info(created mimemessage ...);
msg.setFrom(new InternetAddress(from,
fromName));
_logger.info(from is set ...);
msg.addRecipient(Message.RecipientType.TO, new
InternetAddress(
to, toName));
_logger.info(recipient is set ...);
msg.setSubject(subject);
_logger.info(subject is set ...);
Multipart mp = new MimeMultipart();
MimeBodyPart htmlPart = new MimeBodyPart();
htmlPart.setContent(htmlBody, text/html);
mp.addBodyPart(htmlPart);
_logger.info(body part added ...);
msg.setContent(mp);
_logger.info(content is set ...);
Transport.send(msg);
_logger.info(email sent successfully.);
} catch (AddressException e) {
e.printStackTrace();
} catch (MessagingException e) {
e.printStackTrace();
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
System.err.println(e.getMessage());
}
}
When I look at the log (on the server admin console), it prints the
statement content is set ... and after that there is nothing in the
log. The mail is not sent. At times I get the following error after
the above statement is printed (and the mail is not sent).
com.google.appengine.repackaged.com.google.common.base.internal.Finalizer
getInheritableThreadLocalsField: Couldn't access
Thread.inheritableThreadLocals. Reference finalizer threads will
inherit thread local values.
But the mail quota usage keeps increasing.
Remember this works fine in one application, but not in other. I'm
using the same set of email addresses in both the apps (for from and
to).
I'm really stuck with this. Appreciate any help.
Thank you.
Velu

Re: [appengine-java] How to make GWT + App Engine application crawlable?
I'm using Google plugin for Eclipse to build two identical GWT application
except that one is built with App Engine and the other without App Engine.
Both application are configured with the same servlet filter and mapped to
URL pattern /*
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
HttpServletRequest req = (HttpServletRequest) request;
// query is null when run on App Engine
String query = req.getQueryString();
...
}
When run in the GWT development mode, e.g.
http://127.0.0.1:/X.html?_escaped_fragment_=gwt.codesvr=127.0.0.1:9997,
the
application without App Engine is able to retrieve the query string as
_escaped_fragment_=gwt.codesvr=127.0.0.1:9997.
The problem is, the application with App Engine is always getting the null
query string!
Can anyone help me on this?

Re: [appengine-java] How to make GWT + App Engine application crawlable?
Probably that was a bad query string, but the servlet filter is not able to retrieve the query string from http://127.0.0.1:/Hello.html?A=Bgwt.codesvr=127.0.0.1:9997 too! http://127.0.0.1:/Hello.html?A=Bgwt.codesvr=127.0.0.1:9997 On Thu, Sep 23, 2010 at 10:04 AM, John Patterson jdpatter...@gmail.comwrote: On 23 Sep 2010, at 07:47, hezjing wrote: When run in the GWT development mode, e.g. http://127.0.0.1:/X.html?_escaped_fragment_=gwt.codesvr=127.0.0.1:9997, the application without App Engine is able to retrieve the query string as _escaped_fragment_=gwt.codesvr=127.0.0.1:9997. The problem is, the application with App Engine is always getting the null query string! You need to encode the query string - the character is not allowed in a value. http://download.oracle.com/javase/1.4.2/docs/api/java/net/URLEncoder.html -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.
