[appengine-java] Guice Errors while trying to integrate the sample google app marketplace

[Jaspal Sawhney]

I'm trying to run the sample google marketplace app and my application is 
throwing guice errors in the logs.
*
*
*Setup:* 
1. Java Application deployed Google App Engine
2. Google Marketplace listing pointing to the app.

*Issue*
1. Accessing the application from both directly the appspot.com as well as 
from the universal navigation from within google app results in the 
following error

*Uncaught exception from servlet

[appengine-java] oauth_token_secret does not exist - Accessing Google Calendar using Open Id + OAuth

[Jaspal Sawhney]

 Steps to reproduce issue:
1. Trying to implement a 3 - legged Oauth to access google calendar using 
OpenIdfilter library (which internally uses Step2 and OpenId4Java).

2. Code snippet being used is as follows
*GoogleOAuthHelper oauthHelper = new GoogleOAuthHelper(new 
OAuthHmacSha1Signer());
OAuthParameters oauthParameters = new OAuthParameters();
oauthParameters.setOAuthConsumerKey("jbbssopoc.appspot.com");
oauthParameters.setOAuthConsumerSecret("PcVxBDDTZ9mfnzbVvUe68rCp");
oauthParameters.setOAuthToken((String)req.getAttribute("openid.oauth.token"));
oauthParameters.setOAuthTokenSecret("");
String accessToken = oauthHelper.getAccessToken(oauthParameters);*

3. As per the oauth spec and other posts online setting the token secret as 
"" should not throw an error however I'm getting a 
"*com.google.gdata.client.authn.oauth.OAuthException: oauth_token_secret 
does not exist*" error.

4. If I however make the OauthTokenSecret to " " then I do not get an error 
but do not get the access token. 


Expected output:
1. Expecting the call to return an access token

Actual results:
Error or Empty Access Token

Thanks

Jaspal./

Re: [appengine-java] Re: Weird but Why is my code not getting deployed to the app engine?

[Jaspal Sawhney]

Ok this got resolved. I was doing 1 thing wrong 
I had the logs set to show incase of errors but my app was not throwing any 
errors so had to change the filters.
However I was not able to see the dashboard record any hits at that time - 
however that is working too now.

Thanks for the help.

[appengine-java] Re: Weird but Why is my code not getting deployed to the app engine?

[Jaspal Sawhney]

The version was the same on the appengine console too.
I created a new version. Removed the last one and now I'm not getting
any logs or hits in the dashboard.

[appengine-java] Re: Weird but Why is my code not getting deployed to the app engine?

[Jaspal Sawhney]

Version is 1.0 like it was all the time so far. Also I'm sure that I
have not deployed 1000 times for sure.
Would it make sense for me to change the version # and try?

[appengine-java] Weird but Why is my code not getting deployed to the app engine?

[Jaspal Sawhney]

So it sounds weird but I'm seeing the app engine logs shows errors on code 
snippets which do even exist in my code now?
When I deploy my code to the app engine its not giving me any error.

Is there a limit to how many times can one deploy code to the appengine in a 
day or something?
Any pointers?

Jaspal./

[appengine-java] SSL Issues while integrating step2 library to GAE

[Jaspal Sawhney]

I'm trying to use 'openId-Filter' 
which uses 
'Step2'  lib for OpenId and Oauth 
Integration in a demo app using eclipse (I'm not using Maven)
While trying to integrate the code I'm getting the following error in 
eclipse
1. javax.net.ssl.TrustManager is not supported by Google App Engine's Java 
runtime environment
2. javax.net.ssl.X509TrustManager is not supported by Google App Engine's 
Java runtime environment

Anyone has any idea on how to resolve these errors? also as to why are these 
errors coming - considering that step2 would have been used extensively in 
GAE apps.

Thanks
