Re: [Wrapper-user] problem loading libwrapper.so

[Xavier T. <tx...@gm...>]

Yeah the link didn't actually help. I'm running on Fedora Core 4 with
selinux enabled and the real error is:

INFO   | jvm 1    | 2006/04/18 13:21:17 | Loading native library failed:
libwrapper.so  Cause: java.lang.UnsatisfiedLinkError:
/opt/jwss/lib/libwrapper.so: /opt/jwss/lib/libwrapper.so: cannot restore
segment prot after reloc: Permission denied

so I had to do the following to get it to work:

chcon -t texrel_shlib_t /opt/jwss/lib/libwrapper.so
