[appengine-java] Re: Google Analytics tracking code on GAE

[Prashant]

I am using GWT, Adsense, Analytics and YUI, all of them are working fine
with 
Servlets
.

Anyway, today i tried javascript with JSP also and it works,
http://gaeapptest.appspot.com/test.jsp .

You guys must be doing something wrong or may be your builder is not
recompiling the JSPs every time you change your code and then you feel like
GWE removed JS code ! try creating a new project and share some code next
time if problem persists.

[appengine-java] Re: Google Analytics tracking code on GAE

[YONG]

Prashant,

why I could not use Google Analytics JS code in my index.jsp?
I tried to upload, but the JS code is removed.

If you are not using JSP, what are you using? GWT?

[appengine-java] cron job being executed even though it is not yet time

[victor]

I have a cron job that has the following definition
---
Checks for Expired postings every mon, tue, wed 00:00 (UTC)
2009/10/19 00:00:01 on time Success
-

When I was checking my logs just now, I was surprised that it was run
and today is Sunday. As can be seen on the cron definition, the job is
supposed to run only on mon, tue, wed

Anybody has encountered this issue before?

The only correlation that I could make is I created a new version of
the app and deleted the old one about 10 mins prior.

Where and what did you read?

That doesn't seem consistent with the published limits.  I guess it
depends on what they were doing with the app.

[appengine-java] Re: Google Analytics tracking code on GAE

[Prashant]

you guys meant that GAE removes javascript from your code? i don't think GAE
does any such thing. Currently I am using only servlets (no JSP) on all apps
and all javasrcipts (including adsense & analytics) are working fine. I gave
up using JSPs long back and I don't remember if I have ever faced any such
issue.

[appengine-java] Re: Google Analytics tracking code on GAE

[JonRWarren]

This is a good question. From what I can gather, javascript isn't
allowed in app engine code. Can anyone please verify lack of
javascript support, or if js is supported, please point to references
explaining how to include js in jsp pages.

[appengine-java] Re: javax.jdo.JDOFatalUserException

[Jorge]

Hi Jason,

I am retaking this thread because I am experiencing the same "Caused
by: javax.jdo.JDOFatalUserException..." issue. I'm not using other
frameworks than GAE. The IDE I'm using is NetBeans and I'm using Java.
The PMF singleton is in place, just like explained in the docs.

Thanks,

[appengine-java] Re: GAE Performance

[Geraldo Lopes]

Hi,

Have in mind I'm not demanding anything here.
At this point it probably exists applications in production in google
app engine java.
It would be very nice if you (the ones who developed such apps) could
nicely share with us some numbers, experience etc.

Thanks in advance,

[appengine-java] remote_api for java

[Gaurav]

I understand that the remote_api module is only available for python
for now,
but is it possible to use python's remote_api to manipulate datastore
used
by a java application?
Since remote_api uses lowest level api and datastore is app
independent this
seems to be feasible.
Has anyone tried this?
Can we expect a similar module released for java environment anytime
soon?

[appengine-java] Re: java.lang.IllegalAccessException: Private fields can not be set on JRE classes.

[Toby Reyelts]

Groovy is trying to use reflection to set the private
fieldsof
java.lang.String as an optimization. This only works if Groovy is
granted
unsafe JVM reflection permissions, which we don't do in GAE. When this
fails, Groovy automatically reverts to the safe, normal way of creating a
string, which works just fine.
You're seeing this error in dev_appserver in 1.2.6, because we've done a lot
of work to make the dev_appserver more closely mirror the security
restrictions in prod. If you want to prevent Groovy from even attempting to
try this, you can set the System
property, "stringchararrayaccessor.disabled" to true.

Hey Max,

thanks for your quick reply. After cleaning up I saw that my build
process copied a wrong jdoconfig.xml causing the uppercase behaviour.
Thanks for pointing me to that.

Maybe it's interesting for you (@google) to know that it is pretty
straight forward to change from JPA to JDO. I did not use any fancy
JPA features, but all I had to do is updating my persistent classes
and creating the default jdoconfig.xml. My app now runs with JDO and
there was no need to convert the raw data in the datastore. Nice :)

[appengine-java] Instances of google service objects

I am using google guice with my App Engine application. Is it alright if I
bind instances of DatastoreService, MemcacheService or Service
interfaces as singletons?
In short should I call DatastoreServiceFactory.getDatastoreService(); inside
a servlet method for each request or is it ok to call it once and store the
instance in application startup?

[appengine-java] Re: Persisting java.util.TimeZone

[datanucleus]

DataNucleus itself provides support for persisting TimeZone fields to
datastores (as String). Why not define what your class is and what XML/
annotations you use, and what was in the log ?

okies
Great.. please update on the group for others benefit as well. I find it
pretty time consuming to build JSF  apps w/o IDE support in case of GAE
apps.
Thankx and Regards

 Vik,
 When doing JSF development with the Google AppEngine and the Eclipse
 plug-in, go ahead and select the Google Web Application project.

 You'll have to manually copy the JSF libraries into the WEB-INF/lib
 directory of your web application.  The WEB-INF/

[appengine-java] java.lang.IllegalAccessException: Private fields can not be set on JRE classes.

[aldrinm]

Hi,

What does this exception indicate? "Unable to use direct char[] access
of java.lang.String. Disabling this method.
 [java] java.lang.IllegalAccessException: Private fields can not
be set on JRE classes."
This has started occurring after updating the GAE SDK to the latest
(ver 1.2.7 - 2009-10-15). Tried googling but absolutely nothing! I'm
using grails and do not understand what the framework is doing. Though
the app continues to work irrespective of this error, am curious abt
this. Here is a part of the stack trace.
