Using JNI with Eclipse+MTJ [message #32116] Mon, 13 July 2009 10:23 Go to next message

Hello,

I'm having trouble trying to use JNI with Eclipse and MTJ. My VM
implementation supports JNI so I am trying to create a Midlet that uses
it. I have included the external libraries that implement JNI in the
project build path (but not exported them). Also, in the "Native Library
Location" I give the folder that contains the native libraries (.dll and
h). I am able to compile my project successfully, however I get a
preverification error in the class that declares the native method.

Please, does anyone has some ideas that could help me solve this problem?
Thanks a lot in advance.

Best regards,

María

Hello Craig,

Thanks for your quick answer.
Well, I'm using Sun's Wireless Toolkit 2.5.2. I donŽt have any specific
SDK that supports JNI, but my VM does support it (I use IBM's J9).

Regards,
María

Given that MIDP doesn't, by default, allow for JNI you aren't going to
be able to use Sun's toolkit for this work. The preverification will fail.

I have no idea what SDK you could use for this testing. It would have
to look like a standard ME SDK for MTJ to be able to use it.

OK. Thank you Craig. So far, I havenŽt found that SDK. I'll let you know
if I do.
