I had previously installed the full package of tinyOS, including its
dependencies, such as java, the JNI library, etc; And they were all
working OK. It was on a machine in which ubuntu was running.
Well, some things happened, and we switched to Fedora9.
I reinstalled tinyOS (with a lot of more trouble as there is no way of
installing it through the 'yum' command of Fedora), but when I try to run
some java apps, lots of errors appear, for example, the Oscilloscope
application.
"[EMAIL PROTECTED]:/opt/tinyos2/tinyos-2.x-src/apps/Oscilloscope/java$ java
Oscilloscope.java
Exception in thread "main" java.lang.NoClassDefFoundError: Oscilloscope/java
Caused by: java.lang.ClassNotFoundException: Oscilloscope.java

or:
"[EMAIL PROTECTED]:/opt/tinyos2/tinyos-2.x-src/apps/Oscilloscope/java$ ./run
getenv JNI library not found. Env.getenv will not work
(run the tos-install-jni tool, see man tos-install-jni for more details)"
I've already set the PATH and JAVA_HOME so they have the java installation
dir location there, and I also tried using ./update-alternatives --config
java, and no matter where I say it is, nothing works.
Regarding the JNI library, when I try to install it through the
tos-install-jni command, it returns 'Java not found, not installing JNI
code', but hell, there IS java installed !!!!! And nor do tos-locate-jre
--java or tos-locate-jre --jni return its path ! they do not display
anything at all.
I simply don't know what should I do.. These java stuff are just... Ahw,
driving me mad
Any possible solutions?
(ps.: saying to rerun tos-install-jni or anything related to it will not
help at all, because the tos-locate-jre --* do not return anything, as it
should (and yes, I'm absolutely sure that java is installed, even more
than once actually, and none of its installations are recognized there))
Thanks, Fernando
