Hi there.
I am trying to install swamp on Tomcat 5.5.23 on CentOS 4.5.
After installing the latest version of swamp, 1.5.7, I get the following
when I try to access /webswamp/swamp/
exception
java.lang.NullPointerException
org.apache.turbine.Turbine.doGet(Turbine.java:869)
javax.servlet.http.HttpServlet.service(HttpServlet.java:690)
javax.servlet.http.HttpServlet.service(HttpServlet.java:803)
I've tried to do my due-diligence on this; I've read
http://en.opensuse.org/Swamp/KnownIssues but log files are writing fine.
I've also made sure no -security options are set, etc.
So I tried installing older versions of swap and found that 1.5.3 works
great; but 1.5.4 does not. I then started checking out revisions from
subversion in order to narrow down the problem. The error is introduced
with revision #370. Specifically when this line was added to Data.java:
I18n i18n = new I18n(getClass(), "de.suse.swamp.i18n.Core");
Why this would cause an error I do not know; my java knowledge is not
strong enough. Perhaps it has something to do with this stacktrace
error from catalina.out?

Does anyone have any ideas? Am I missing something in my tomcat config?
Any assistance is greatly appreciated. Thanks!
