The same thing happen to me. I think this is a debian java-package bug.
The IBM Java try to find its home directory by following the symbolic link.
(File /usr/bin/java should be a symbolic link on your machine.) But the IBM
Java follow the symbolic link only once, which cause the problem.
In the default debian settings, /usr/bin/java is a symbolic link
to /etc/alternatives/java, and /etc/alternatives/java is a symblic link to
/usr/lib/j2sdk1.5-ibm/bin/java.

If you strace java binary, you will find the problem. The java binary
find /usr/bin/java is point to /etc/alternatives/java, and consider
directory /etc is java home directory. Then it try to find libjvm.so under
directory /etc and failed.

Here is my work around solution. Remove all the java stuff under /usr/bin,
and re-create them.

jarsigner java javac javadoc javah javap java-rmi.cgi \
javaw javaws jconsole jdb jdmpview keytool native2ascii \

rm /usr/bin/$f
ln -s /usr/lib/j2sdk1.5-ibm/bin/$f /usr/bin/$f
done

BTW, there is a mozilla plugins in IBM Java 1.5. So you can watch java applet
with mozilla or firefox. Just create the symbolic links as the following.
~~~snip~~~
ln -s /usr/lib/j2sdk1.5-ibm/jre/bin/libjavaplugin_oji.so \
/usr/lib/mozilla/plugins/
ln -s /usr/lib/j2sdk1.5-ibm/jre/bin/libjavaplugin_oji.so \
/usr/lib/mozilla-firefox/plugins/
