What steps will reproduce the problem?
1. Use the GData Java Client within the Google App Engine SDK for Java
2.
3.

What is the expected output? What do you see instead?
Expected is to be able to fetch a Contacts feed for example. Instead an error 
gets thrown which is most likely due to a restriction within the App Engine SDK


What version of the product are you using? On what operating system?
GData 1.30.0 + App Engine SDK 1.2.0 + Windows XP


Please provide any additional information below.

Workaround seems to be to disable automatic cookie handling by calling:

service.setCookieManager(null);

just don't know about the side effects...

Actually the right way to disable automatic cookie handling (which would 
currently be needed due to the restrictions of the App Engine Java Environment) 
is to set the according system property:

System.setProperty(GoogleGDataRequest.DISABLE_COOKIE_HANDLER_PROPERTY, "true");

Unfortunately this results in getting an error because of missing 
authentication header information:

java.lang.NullPointerException: No authentication header information

interestingly java.net.CookieHandler seems to be on the white list for Google 
App Engine: http://code.google.com/appengine/docs/java/jrewhitelist.html.

Still, invoking this code:

java.net.CookieHandler.setDefault(new CookieHandler(){

    @Override
    public Map<String, List<String>> get(URI uri,
            Map<String, List<String>> requestHeaders)
            throws IOException {
        return null;
    }

    @Override
    public void put(URI uri, Map<String, List<String>> responseHeaders)
            throws IOException {
    }
});

results in an java.security.AccessControlException: access denied 
(java.net.NetPermission setCookieHandler) error.

Its kind of a readonly access.  You can use the default cookie handler, but 
cannot
inject your custom handler.  So you need the system property.

As far as the authentication issue., could you send me the http trace for the 
failing
auth request?

Weird I retried gdata client lib 1.30.0 with appengine 1.2.0 sdk.  I couldnt
reproduce the issue.  Please send me the wire trace, that may provide more 
clues into
why you are seeing that error.

While preparing the HTTP traces, I found the following:
it seems as if the problem occured because of a wrong authentication scope when 
generating the auth sub url using AuthSubUtil.getRequestUrl(...).

I used: http://www.google.com/m8/feeds/ (this failed) - when I am using: 
https://www.google.com/m8/feeds/contacts/default/full it works.

The official documentation 
(http://code.google.com/intl/de-DE/apis/contacts/docs/2.0/developers_guide_proto
col.html#auth_sub) however says to use http://www.google.com/m8/feeds/.

By the way, I do not have any of these problems when using the Docs API instead 
of the Contacts API.

Regarding the traces: I prepared them, but it seems as if there is a lot of 
sensitive data in there - which parts do I need to remove before posting them 
here?!

Did you try the contacts API or a different one? I have an idea why it fails: 
if the 
the auth scope is using a different protocol (e.g. http instead of https) than 
the 
requested URL has, a NullPointer exception gets thrown.

I havent had chance to look at this issue.  It should work with http as well. 
weird.

Is this blocking you? or using https is an acceptable solution for you?

Having the same issues (google apps + gdata 1.30) - tried
service.setCookieManager(null) - no luck

The code works when running from a shell and retrieves portfolio data

Through commenting/uncommenting it seems that one can authenticate but using a 
feed
from the FinancialService produces a security exception.

FinanceService service = new FinanceService("MyService-1.0");
service.getAuthTokenFactory().getAuthToken();
service.setUserCredentials("[a valid email]", "[a valid password]"]);

//OK to Here

String feedUrl = "http://finance.google.com/finance/feeds/default/portfolios";
//Requesting Feed 
PortfolioFeed portfolioFeed = _service.getFeed(new URL(feedUrl), 
PortfolioFeed.class);

//Dies with the following stack

I see there is a new load of gdata (1.31). Mine is 1.30. Does anyone know if the
update fixes tis issue? Nothing about it in the release notes

I'm having the same problem with the spreadsheets API.  Adding 

<system-properties>
  <property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>
to the web.xml didn't seem to help with using 1.30.0 and earlier.  I can't tell 
if
1.31.1 has this changed since 1.31.1 throws an exception on creating the 
service. Am
I doing something wrong?

zed163,

Are you referring to issue with authentication or disabling cookie handler in 
appengine?

Sorry my fault. 
<system-properties>
  <property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>

do you still have the problem after disabling the cookiehandler?

<system-properties>
  <property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>

solution (for me) : put 

<system-properties>
  <property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>

 in  eclipse_project/war/WEB-INF/appengine-web.xml

This worked for me as well.  I don't know if there are any negative 
side-effects yet.

Well, for those asking about the side effects of disabling the cookie handler, 
it's 
pretty brutal in my case: the app won't deploy while using the Eclipse plug-in.

com.google.apphosting.utils.config.AppEngineConfigException: XML error 
validating 
C:\Documents and Settings\User\My Documents\Java\workspace\Contacter\war\WEB-
INF\appengine-web.xml against C:\Documents and Settings\User\My 
Documents\Java\eclipse\plugins\com.google.appengine.eclipse.sdkbundle.1.2.8_1.2.
8.v20
0912062003\appengine-java-sdk-1.2.8\docs\appengine-web.xsd

Removing the bit from appengine-web.xml will allow deployment but cause an 
exception 
at run time.

Any solution?

Does not happen to me with 1.39.1 release, consider updating.

As per release notes in 1.40.2 there is no need to use:

<system-properties>
  <property name="com.google.gdata.DisableCookieHandler" value="true"/>
</system-properties>

I have just tested.

I got same exception while GoogleGDataRequest is initializing:
"Caused by: java.security.AccessControlException: access denied
(java.net.NetPermission getCookieHandler)"

althought I updated to  1.40.3

I'm using GData (Picasa) in a web application deployed with Apache Tomcat 6 
with Jdk
1.6_07, setting System.setProperty("com.google.gdata.DisableCookieHandler", 
"true");
fixed my problem.

I just took a look at the changes which was made to fix this bug at
http://code.google.com/p/gdata-java-client/source/detail?r=114.
The diff for GoogleGDataRequest.java shows the class
"com.google.apphosting.api.ApiProxy" is required to make that fix work, but this
class is in my environment not availabe cause I don't use Google apphosting 
api..

The fix was intended to make it workable in Google App Hosting environment.  If 
this is 
another restricted environment use the system property.

I am facing the issue while getting data into the GAE. 
I have created a jar file which gets all the data from the domain using the 
admin
userid and pwd. Now, I am using this jar into my webapp and getting the list of
users/document in the domain.

1. I am getting proper output in Eclipse console (i.e. 3 users/11 docs)
2. When i deploy the same to GAE, it does not show any users/docs.

Question: Has anyone faced the above issue. 
I am using 1.3.1 SDK.

Please let me know how to get rid of this issue (comment #31)...

System.setProperty(GoogleGDataRequest.DISABLE_COOKIE_HANDLER_PROPERTY, "true");

This worked perfectly for me :)

I'm using Single-user "installed" client authentication though

 coolprosu where exactly did you use :
System.setProperty(GoogleGDataRequest.DISABLE_COOKIE_HANDLER_PROPERTY, "true");

it seems to make no difference to me :(
