Hi,

This isn't the "real way" to add tool chains (but given that 4.5.2
tool chains support is a bit hacky to say the least....).

You could create a tool chain in toolchain.tcl which would only
have JAVA support (i.e. only a Java toolchain)

This example is close to what you want:

# Sun Java compiler toolchain.

set sunjava [snToolChain SunJavaTarget]
$sunjava SetIsEmbedded 0
$sunjava SetShortName sunjava
$sunjava SetDebuggerName gdb
$sunjava AddRule JAVA .class.o javacc "-c $<"
$sunjava AddRuleInfo JAVA "Java" "Compile a Java file"

# does suns compiler need an entry point.
# $sunjava AddExeLinkerEntryPointFlag JAVA "--main="

$sunjava AddRuleSuffix JAVA .class

#DEBUG FLAGS
$sunjava AddRuleFlagSet JAVA Debug "" DBG_DEFAULT

#OPRIMIZATION FLAGS
$sunjava AddRuleFlagSet JAVA Optimize "" OPT_DEFAULT

#CODE GENERATION FLAGS
$sunjava AddRuleFlagSet JAVA CodeGen "" CG_DEFAULT

#WARNING FLAGS
$sunjava AddRuleFlagSet JAVA Warning "" WN_DEFAULT



You need to find all the hard coded bits for selecting
a tool chain (5.0 will handle this much better).

Another alternative would be to just modify the GNU java
compiler support to use the Sun Java compiler.

Anyway, hope this is of some use to you.
Thanks,
    Ian.
