I am having problem consuming a web service written in asp.net/vb.net hosted at http://www.transmodallimited.com. After writting the code i discovered that the app wasn't really hitting the web service. So, in order to be sure, I went testing with the httpconnection demo and discover that even the httpconnection demo is not working. I tried switching the MDS on, tried adding ';deviceside=true' to my link and it still not working.
If you want to use KSOAP2 you can use this link BlackBerry and Ksoap2 Tutorial. Also see this thread on suppots forum Consuming .NET Web Service With BlackBerry JDE 4.6, Java Wireless Toolkit and KSOAP. If you want to use jsr-172 compliant stub you can use Calling a Webservice from Blackberry Java Application.
I strongly recommend you to use any sniffer tool like Wireshark in order to trace any HTTP/XML packages, if there isn't any HTTP/XML package, and your MDS is running before you run your application, then the problem could be in your code.

I have a Google AppEngine (Java) project in Eclipse. I want to debug my local code in Eclipse but use the deployed database on AppEngine. Until now I use Remote API with username/password (old way)
This method will be deprecated and I want to use OAuth but when I try to use it, it throws an exception:
java.lang.IllegalStateException: OAuth-based authorization not supported for clients running on App Engine
at com.google.appengine.tools.remoteapi.RemoteApiOptions.getOrCreateHttpTransportForOAuth(RemoteApiOptions.java:359)
at com.google.appengine.tools.remoteapi.RemoteApiOptions.useApplicationDefaultCredential(RemoteApiOptions.java:162)
Everthing is fine when I run a simple Java client app that uses remote api in Eclipse. But if the client is AppEngine development environment in Eclipse, it doesn't work.
How can I debug the server code in eclipse using appengine database?
Bug report: https://code.google.com/p/googleappengine/issues/detail?id=12556
This is expected, as value returned by ApiProxy.getCurrentEnvironment() will not be null, but com.google.appengine.tools.development.LocalHttpRequestEnvironment object. For development server you'll have to use old style (username/password) for now.
According to the documentation, you need to add appengine-remote-api.jar from ${SDK_ROOT}/lib/appengine-remote-api.jar to your WEB-INF/lib directory (or add it to your Maven dependencies) before this will work.
Update: Indeed, it looks like OAuth from App Engine with Remote API has not yet been implemented. I would assume this will change before ClientLogin is fully deprecated, but for now I would recommend opening a feature request on the public issue tracker.
One possible workaround would be to create a regular console application that connects to the Remote API (as per the example in the docs) and can act as a proxy for your App Engine application running on the development server.
In addition to what my colleagues Adam and Nikita previously said, I can officially confirm that the Google Cloud Engineering Team is determined to provide a solution to all reasonable use-cases which are affected by the ClientLogin shutdown before its deadline.
Presumably, the Remote API solution will be available in the upcoming releases 1.9.31/32, although this is just an assumption and there's no ETA for it yet.
As an alternative, you can access Cloud Datastore using Protobufs remotely using service account credentials, which might fit your needs for the moment.
UPDATE 2016/01/21:
The team has extended the ClientLogin shutdown deadline to April 12, 2016.
UPDATE 2016/04/12:
As mentioned before, the fix was properly applied and available in the latest versions of the SDK and gcloud. Remote API can now be used again with OAuth for app-to-app (or devserver-to-app) connection.
I'm trying to develop a small server which would include one restful webservice.
I'd like to use JAX-RS for the webservice part, but every example I'm seeing is using a tomcat server, and I can't use any 'application' server (meaning I can create a server in my code, but can't run it from the outside).
Well anyway I was wondering if anyone had any sample to show, and any advice on which light library I could use to run such a simple server into my code (can't use any gpl /lgpl etc licence, so no jersey for example).
Thank you.
It's possible to embed Tomcat in your application, see here for an example: http://java.dzone.com/articles/embedded-tomcat-minimal
Another popular choice for an embedded servlet container is Jetty, they have a tutorial here.
Edit
The examples provided with Jersey can also be helpful, here's one for running using the Grizzly HTTP library: https://github.com/jersey/jersey/blob/master/examples/helloworld/src/main/java/org/glassfish/jersey/examples/helloworld/App.java
You can even use the HTTP server that's bundled with the JDK (probably not the way to go for a real application): https://github.com/jersey/jersey/blob/master/examples/helloworld-pure-jax-rs/src/main/java/org/glassfish/jersey/examples/helloworld/jaxrs/App.java
Have you checked out http://www.sparkjava.com/?
It's very light-weight and concise.
Building a server into code is nothing. See "Embedding Jetty", for one. There are plenty of other options with varying degrees of difficulty and capabilities, like the Simple Framework, Tomcat, Grizzly, Netty, and Vert.x, to name a few. Then, if you're not stuck with Java, the language, there's Ratpack for a lightweight REST server. Otherwise, running something like Jersey in an embedded server is quite simple. I do it every day in tests.
I'm a PHP Developer and Web Designer. In my work a partner asked me if I could set up a Google Cloud Messaging server.
I read the documentation but couldn't find a clear tutorial to set up this server.
I got no knowleadge about Java so it makes my job harder. I could "compile" a war file using ant as GCM Demo Tutorial says. But I can't deploy it to my AppEngine server to try it out (It's my first time using AppEngine too).
Could you give me some steps to create my own GCM server?
Sorry about my bad english.
Thanks!
A easy way to import the gcm-server-demo to eclipse:
①Download a “Eclipse IDE for Java EE Developers”，and create a dynimic web project.
②Copy the ‘src’ and ‘webcontent’ from the gcm-server-demo to cover the web project.
③Add a server like tomcat or jetty to run the project.
And the registration id is sent by the Android application with a 'Post' request.
You can handle it with servlet or PHP
I've read some articles on the Internet that this is not possible. To communicate own SQL database that is located on other server from GWT application. Jetty doesn't allow it.
I found a way how to perform it but it's not very cosy. I have client and server part inside GWT. The server has to communicate with MySQL database on localhost. So I've written an ant script to build a war that I can launch on Apache Tomcat server. It works perfectly there but I'm not able to debug the code effectively.
Do you have some advices how to perform this task? I was thinking of writing the clienty only in GWT and find some waz how to communicate my own server written outside the GWT. I've found Apache Thrift for GWT but this edited library of thrift seem not to work properly.
Thank you very much for your answers:)
It is possible to communicate with a database from a GWT application. The client side has to call the methods of the server via GWT-RPC, which can communicate with any database.
Maybe Jetty does not support it (have not tested it personally) but you can develop your web application using Apache too. There you can access the database the same way as from any web application:
You will need the mysql-connector-java-5.1.20-bin.jar file (downloadable from: http://dev.mysql.com/downloads/connector/j/ ), and restart the server added to the $CATALINA_HOME/common/lib directory.
OR added to the WEB-INF/lib folder of your web application.
You can find tutorials online of how to develop an application using Tomcat instead of Jetty. For example: https://wiki.auckland.ac.nz/display/BeSTGRID/Deploying+GWT+to+Tomcat+in+Eclipse
Reshi, stop and think about how applications really work. Nobody provides web pages with javascript to read/write databases, that would be crazy and unsecure. Servers are always in themiddle of all communication in this case. You need to create services that run inside your server, one of these services will be a database layer.
Javascript cant create network connections and read/write binary data, thus it would be insane to attempt to get the gwt compiler to compile any jdbc drvier and more.
Jetty does NOT stop us from connecting to a database. All you have to do is to follow the MVP model way. Although MVP is better bet against all hurdles, at a minimal point, you would have to try not having SQL code on the client package.
I am new to jetty. I want to use jetty web socket in my application. I tried my best but unable to find a good tutorial how to write server and client. I want to write client in jquery and server in JAVA EE 1.6.
I used http://wiki.eclipse.org/Jetty_WTP_Plugin/Jetty_WTP_Websocket_Wizard
but there is some library error on private Outbound outbound; So Please help me by providing a good tutorial having implementation in eclipse, jetty and jdk 1.6.
I will be really very very thankful to you all.
The wtp wizards have not kept up with the latest released drafts (nor the final release of the spec) of the websocket protocol.
for an example of a websocket client and server in jetty take a look at the cometd project, they have a fully working setup with it.
http://cometd.org/
Alternately take a look at the test cases in jetty-websocket itself for other examples of working client and server examples in java.
