I have installed AppEngine Eclipse plugin for Juno according to the instructions here: https://developers.google.com/appengine/docs/java/tools/eclipse
However when running a number of the provided sample projects (eg. ShardedCounter), a NoClassDefFoundError would be thrown, stating that class com/google/appengine/tools/development/DevAppServerFactory$CustomSecurityManager$StackTraceAnalyzer cannot be found:

The only modification I did to the sample projects was to remove the usage of Google Web Toolkit, as the test server could not be started if GWT is used. I have just started trying out AppEngine, any help is greatly appreciated.
You need to add specific jars to your classpath so that they are available during runtime
Set Eclipse to use JDK 7 seem to fix the issue, which explains why it runs on the actual App Engine server but fails locally. Still the error it gives is quite strange...
Probably will do further testing and update the info.

I want to connect my Google App with SAP to retrive data from SAP.
I tried using SAP Java Connector in simple Java application and it worked fine.
However it thorws an exception when I try to do the same thing in Google App.
Here is my code :
public static final void getConnection() {
Properties connectProperties = new Properties();
connectProperties.setProperty(DestinationDataProvider.JCO_ASHOST, SAP_IP);
connectProperties.setProperty(DestinationDataProvider.JCO_SYSNR, "00");
connectProperties.setProperty(DestinationDataProvider.JCO_CLIENT, "350");
connectProperties.setProperty(DestinationDataProvider.JCO_USER, SAP_USER_NAME);
connectProperties.setProperty(DestinationDataProvider.JCO_PASSWD, SAP_PASSWORD);
connectProperties.setProperty(DestinationDataProvider.JCO_LANG, "en");
try {
JCoDestination destination = JCoDestinationManager.getDestination(SAP_DESTINATION);
System.out.println("Attributes:");
System.out.println(destination.getAttributes());
System.out.println();
destination.ping();
} catch (JCoException e) {
e.printStackTrace();
}
}
Here SAP_DESTINATION, SAP_IP, SAP_USER_NAME and SAP_PASSWORD are the String variables having respective values.
Here is the exception thrown when I call this getConnection() method:

This same code works fine with simple java app.(Without Google SDK for Java)
Can any one confirm that the JCO jar is compatible with Google App or not.
Is this a issue with JCO or Google sdk ?
Or Can any one suggest me some other way to connect Google App with SAP.(instead of JCO)
The SAP Java Connector offers a platform independent API for Java, but itself is platform dependent. It needs to load a platform dependent native library.
Please see SAP note 1077727 for a list of supported JREs and operating systems.
The SAP Java Connector uses the RFC protocol for communicating with SAP systems. As an alternative you may use HTTP/HTTPS instead. Please have a look at the Internet Communication Framework (ICF) and the Internet Communication Manager (ICM) for this. Maybe this link will be useful as an introduction:
https://help.sap.com/saphelp_qim100/helpdata/EN/48/641ea1bdbc51eee10000000a421937/frameset.htm
I've tried the following combos and can't get rid of this error:
Spring Boot 1.1.6 RELEASE and Spring 4.0.7
Spring Boot 1.2.0 RC1 and Spring 4.1.2
Declared a custom DispatcherServlet with event publication disabled
#Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet() {
DispatcherServlet dispatcherServlet = new DispatcherServlet();
dispatcherServlet.setPublishEvents(false);
return dispatcherServlet;
}
This is similar to Exception from running spring-boot-legacy but that issue has been fixed and the exception that I am getting now does not appear to be covered by the Spring Bug (https://jira.spring.io/browse/SPR-12151).

Unfortunately, I didn't have enough understanding of how everything was connected to figure this out quickly via the stacktraces.
I have a problem running jsf + primeface on app engine. Specifically I have:
primefaces 3.4.1
jsf 2.1.7
appengine sdk 1.8.9
Java 7
I get the following exception on every page I load. However if I refresh the page it loads normally. I started having this issue only when I migrated to appengine 1.8.9. Previously I was using 1.6.6 and everything was running smoothly.
I searched around and it seems that this is a common issue. However I couldn t find any solution. Anybody has an idea about that? Thank you

Number conversion software varies in how lenient or strict to be about number formats. The one in BufferUtil looks rigid and quite strict.
Try logging or outputting the String you wish to convert, between some delimiters, and look for other suspicious characters that may have crept into your String as a result of the software upgrade. Even a '+' or a trailing space can spoil the party.
I have a Google App Engine project that I'm trying to implement Google BigQuery for XML caching.I'm using the CredentialUtils class from BQ tutorials for offline web server authorization. I have created the client_secrets and all that.
I've been trying my best for solving this, tried newest library releases yet to no avail. What would you suggest?
Here's the error log.

Not sure if I understand the question, but why not use App Engine Service accounts? https://developers.google.com/bigquery/authorization#service-accounts-appengine
I am trying to use Dropbox's java API in GAE to override a dropbox file.
I am using putFileOverwrite API to the override file contents however the api throws an "access denied (java.lang.RuntimePermission modifyThreadGroup)" error. Which I figured out was due the fact that multithreading programming is not allowed in GAE, so i updated the code in AbstractSession.java wherein i made IdleConnectionCloserThread a normal class and not a thread.
Now when i try to run the function, i get java.net.Socket exception.
Does any1 have any suggestions as to how to get the Dropbox + GAE setup working ?
The source code :
AccessType ACCESS_TYPE = AccessType.APP_FOLDER;
AppKeyPair appKeys = new AppKeyPair(APP_KEY, APP_SECRET);
AccessTokenPair accessTokenPair = new AccessTokenPair(ACCESS_TOKEN, ACCESS_KEY);
WebAuthSession session = new WebAuthSession(appKeys, ACCESS_TYPE, accessTokenPair);
DropboxAPI<WebAuthSession> dropboxApi = new DropboxAPI<WebAuthSession>(session);
String fileContents = "Hello world";
ByteArrayInputStream inputStream = new ByteArrayInputStream(fileContents.getBytes());
try
{
dropboxApi.putFileOverwrite("/myFile.txt", inputStream, fileContents.length(), null);
}
catch(DropboxException e)
{
}
The exception i get after using the dropbox's jar AS-IS :

This shows up very high in a Google search for Dropbox gae, so for those who stumble upon it:
The java sdk as of this post will work with GAE provided you replace the use of HttpsURLConnection with HttpURLConnection. GAE will handle https automatically.
