hello ,
i've installed sun's jdk/jre with linux emulation fro pkgsrc (
pkgsrc/lang/sun-sdk15 & sun-jre15 )
did all the things i think i had to do to make it work
like mount emul linux procfs , set env variables ( JAVA_HOME , CLASSPATH
) etc ,
so far java (with linux emulation) works fine ,
the problem started when i installed the j2me toolkit ,
(it is used to create java applications for mobile phones and some
embedded boards)
exact name : j2me_wireless_toolkit-2_2-linux-i386.bin ( it's linux and
it will run with emulation as jdk)
everything went ok with installation and running , i could run
precompiled example applications ,
but ,
couldn't compile new ones ,
after a while a traced it down to , toolkit not being able to load and
use the "javac" class
decompiled code from sun's toolkit
try
{
class1 =
toolLoader.loadClass("com.sun.tools.javac.Main");
method = class1.getMethod("compile", new Class[] {
java.lang.String[].class
});
}
this error is easy reproduced if unset the CLASSPATH env variable
and compile any java program that makes use of loadClass(".....javac.....")
i found out that the script to fire up the toolkit ( ktoolbar )
actually uses :
javac -cp {location libraries of toolkit} other_options other_options
this way it overrides totally (i think) the CLASSPATH env which points
to the correct tools
and here is the problem ,
if i add javac -cp location_libraries_sdk15:location_libraries_wtk it
works ok ,
since i've recently switched from debian to netbsd at the computer where
i work ,
i digged a little at my back up tapes from linux , and didn't observed
anything
that could reproduce this problem on linux
a friend of mine (with more java background than me and mostly a freebsd
guy )
pointed out that this might be happening due to not having a "native"
installation of java
so ,
a) has anyone any thoughts on this ? could this be happening due to non
native java ( sun-jdk instead of scsl-source-jdk )
b) could someone reproduce this with a native java installation ?
(from what i have tried on my system it's enough to just visit
http://www.javaworld.com/javatips/jw-javatip131.html?page=2
download the simple example ,
and compile with out specifying "-cp" at the command line.
if we find a good solution ,
we can fix wip/sun-j2me package which has set PKG_FAIL_REASON
for quite a while now i think ,
thanks in advance
