Why rmic does not compile the remote interface implementing?

On platform RH8.0, J2SDK1.4.1_02, I use rmic to compile the implementing class of remote interface, but output the following message. On window2000, J2SDK1.4.1_02, the rmic works fine. Could someone tell me why the rmic does not work on RH8.0? Thanks very much!

At the command prompt where you are trying to RMIC, check the version of Java you are running using java -version.
Also check which java at the command prompt. Is it pointing to your JDK1.4?

And, please check if the classpath is set correctly? the rmic has the option classpath to locate the relative classes.

I checked the rmic compiler(which rmic), the system showed me that /usr/bin/rmic. So, in RH8.0,
there two rmic, one is at /usr/bin/rmic and the other is at /usr/java/j2sdk1.4.1_02/bin. In fact, the rmic in JAVA_HOME should be used.
Thanks all of you!

Hi Light,
Do you have kaffe installed? (try rpm -q kaffe) - if so, then I would recommend you uninstall it (if you are allowed to) since you dont really want to have two java compilers installed.
(For anyone interested: Kaffe is a cleanroom implementation of Java (that is, it was developed by people outside of Sun based purely on the published documentation from Sun) that was developed when Sun used to release each version of Java for Linux several months after they had released the version for Solaris and Windows).
If you dont have kaffe installed, it might be worth trying to find out what has installed the non desired rmic compiler. Try rpm -q --whatprovides /usr/bin/rmic. Once you have found out what the package is, decide if you really need it - other similar problems could also occur with other clashes in executables, or libraries, or .....
By the way, there is a Linux forum in JavaRanch - perhaps this question should have been raised there?
Regards, Andrew

Hi Andrew,

Thank you very much! You are right!

On RH8, other three packages need libgcj. I use rpm -e to delete all of them. Now, I do not need to specify the path of rmic. rmic works fine.
Thank your reply on this and linux forum.
Regards, Light rpm -e
I agree. Here's the link:
