Hi Wu, IoTivity Simulator Core is implemented with pure IoTivity code which align to the latest IoTivity code rom Jenkins and Scons always. More specifically, simulator consists of, Eclipse Simulator Code ? Simulator specific Java API ? JNI Wrapper ? Simulator centric C/C++ IoTivity Code ? IoTivity C/C++ API from Layer perspective.
Regarding porting concept, I believe IoTivity language/platform port should be on top of common IoTivity layer instead of coap library independent from IoTivity repo. This is only tool resolve the language/platform variation.

Hi, My changes already include a working SimpleClient/SimpleServer working with Java Bindings, you should be able to compile them by running ./auto_build.sh linux_unsecured_with_java on the latest patch in the change. To run the simpleclient you will need to run these commands in the root iotivity folder, assuming you have not changed the output folder: export LD_LIBRARY_PATH=$(pwd)/out/linux/x86_64/debug/:$LD_LIBRARY_PATH java -cp java/examples-java/simpleclient/build/libs/simpleclient.jar:java/iotivity-linux/build/libs/iotivity-linux.jar org.iotivity.base.examples.SimpleClient What I could use help with is removing the dependency on Android from the other examples in java/examples-java.

I am trying to work on a client application to make request to iotivity cloud server or iotivity resource. There is already C/C++ library running on Linux, I am thinking wrapping it with JNI will enable Generic Java development, that is what you are working on, it that right? I will take a look at your changes and see if I could create a simpleclient with it. One more thing, wiki has a Iotivity Simulator which run on Eclipse. It is a Java wrapper on simulator core. I am wondering what this simulator core actually do. Will I able to import this library and use it to communicate with a genuine iotivity server? Or maybe I could try to understand what CoAP message it sends out and develop a generic CoAP client to talk to iotivity server? If the CoAP and application layer protocol of Iotivity is not going to have a drastic change, implementing a generic Java CoAP client could be a viable solution.

Hi Maxi, I am currently on getting Java API working on Linux, but review and testing might take a while since it?s a major change in how the Java API is being built for Android as well. For now transport is only IP, no BLE. You can find my changes here: https://gerrit.iotivity.org/gerrit/#/c/7895/, and you should be able to build and run the simpleclient and simpleserver examples, or your project as well. The API documentation should be very similar to the Android one, minus Activity or Context. However, keep in mind that some things might change and not everything has been tested thoroughly, and there?s no official documentation for how to build and run a program right now, although I can offer you help here, if you need any. -- Petre Eftime From: iotivity-dev-bounces at lists.iotivity.org<mailto:iotivity-dev-bounces at lists.iotivity.org> [mailto:[email protected]] On Behalf Of ???(Uze Choi) Sent: Wednesday, April 27, 2016 12:14 PM To: 'Maxi Wu' <maxi.wu at u-media.com.tw<mailto:maxi.wu at u-media.com.tw>>; iotivity-dev at lists.iotivity.org<mailto:iotivity-dev at lists.iotivity.org> Subject: Re: [dev] Is it possible to port the Java(Android) API to general java application?

Hi, Java is cross-platform, but JNI uses native library. Is it possible to use this Android API like normal JAVA application? If not, How to create a Java client? Do we need to interact with iotivity cloud using CoAP?
