jsvc - Cannot register native methods error
Would greatly appreciate insights into "Cannot register native methods"
error below encountered while trying to start tomcat 6.0.29 using jsvc on 64
bit RHEL 5.5. Suggestions to fix this problem in the past have involved
making sure commons-daemon.jar was in class path, this does not appear to be
my issue in this particular case. Downloaded and built jsvc from src. I've
included debug output below from jsvc. Thanks so much for any suggestions

Problem solved - thanks for your response. I had built native portion of
JSVC but failed to build the java portion (ant dist) commons-daemon-1.0.3
jar. My script was using the commons-daemon.jar found in the apache tomcat
6.0.29 bin directory when I should have updated it with
commons-daemon-1.0.3.jar instead. Updating the jar to match built binary
version did the trick. Thanks again,
Jason

I suppose you have done what README says:
$ export CFLAGS=-m64
$ export LDFLAGS=-m64
$ ./configure
$ make
If you have compiled jsvc from the
commons-daemon-native that comes with 6.0.29
you will need to (some trash left in distro)
$ make clean
and the repeat the upper export; configure; make procedure
However I'd suggest to use 1.0.3 binaries
http://www.apache.org/dist/commons/daemon/binaries/1.0.3/linux/
(They were compiled on RHEL5, so should work)
