Java Development

[tibi95]

Hello,

I've created a small JAR file with some classes inside, to be shared between BlackBerry and Android platforms (let's say "common.jar").

I've preverified this JAR for BlackBerry and I've added in Eclipse project, and the application is working on Emulator.

The building for device (using a build.xml with blackberry ant tasks) is working, but after installation on the device, when I want to start the application I receive an error:

"Error starting app_name: Module 'common' not found."

So, I have some java files (for BlackBerry platform) and this JAR (for common code).

Can you help me with this BB ant tools? For sure the problem is with these tasks parameters (I've read the documentation), but I cannot handle

Thank you very much,

Tibi.

Hello,

Meantime I found a solution: the external preverified JAR file must be included together with the rest of the project files.

If you are using the "import" attribute of rapc, it is not enough: the application just compiles ok, but that external JAR (or its content) is not added in final COD files.

I fixed this stuff in the following way:

<rapc destdir="${dest.dir}" output="${app.name}" jdehome="${jde.home}" jdkhome="${jdk.home}">
  <src>
    <fileset dir="${app.source}"/>
    <fileset file="${external.lib}"/>
  </src>

  <jdp ....

Maybe you know a better solution...

The other solution is to import them and load COD's for those libaries with your main app.

If those JAR's are simply interface stubs, you won't get anything useful by fusing them into the distribution.

To clarify what dnepr said, since it took me some research to figure it out.

If you compile a library file in eclipse, as part of compiling the main application, then you will find a library.jar file in the deliverables folder of the library project.

That jar file only contains interface stubs, with no actual method implementations.

If you want your library.jar file to contain valid code, it must not be compiled in this way.
