Eftime,
Report on what I've done so far. I've try ./auto_build.sh linux_unsecured_with_java on iotivity root folder, it shows done building target. I do not change the output folder. And then I run the java -cp command, I believe this is to configure the classpath. There is no file inside folder $(pwd)/out/linux/x86_64/debug/java/examples-java/simpleclient But there is a simpleclient.jar found in $(pwd)/java/ examples-java/simpleclient/build/libs I am not sure where do I mess up the build process. I do managed to import the gradle project found inside $(pwd)/java into my Eclipse Mars. There is an error saying that line 20 of build.gradle value of $TARGET_OS not defined, could be because this script is for Scons. I edit it to /iotivity-linux/build/libs/ then I am able to import it. I think I could somehow manage to use JNI with files inside $(pwd)/java/jni with those .so library to test Iotivity. But would be better if I could do things in your way in order to make changes and commit back to gerrit. If I run SimpleServer project inside Eclipse under debug mode. This line will have linking error OcPlatform.Configure(platformConfig); <- UnsatisfiedLinkError It could be telling me that it couldn't find the library file which is trying to link with. I am still working on this issue. Could you please share with me what kind of development environment you are using to wrap iotivity with JNI?

Eftime, I have checkout the source from IOT-1089, and have some trouble trying to build it. Not familiar with Scons. If I run ./auto_build.sh, first time g++ gives me a virtual memory used up error. I tried it after expanding my memory, it ends with "done building target". Then I look into the /out folder, there is /linux/x86_64/release, inside /resource/example with executable files of c. I looked into SConstruct, auto_build.sh and Readme.scons.txt, I should be looking for folder generic_java/examples, is it? I have also tried the build command "scons RELEASE=true BUILD_JAVA=ON", gives me an error "AttributeError 'SconsEnvironment' object has no attribute 'Download': SConstruct line28 I've also tried to import gradle project found in folder /java/examples-java to Eclipse Mars, a gradle project preview failed window pop up. Could not fetch model of type 'GradleBuild' ysing Gradle distribution http://services.gradle.org/distributions/gradle-2.2.1-all.zip Please give me some information or what command to use, on how to build java examples and core for Linux platform.

Eftime, Thank you. Glad to have any help with Java API. 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: [email protected] [mailto:iotivity-dev-bounces at lists.iotivity.org] On Behalf Of ???(Uze Choi) Sent: Wednesday, April 27, 2016 12:14 PM To: 'Maxi Wu' <maxi.wu at u-media.com.tw>; 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? -------------- next part -------------- An HTML attachment was scrubbed...
