Problem accessing domino database by jsp

Hi all,

i'am running an tomcat server with an web-application accessing domino
by jsp-pages. on my win32 workstation everything run's fine. but on my
linux server (which is SuSE 7.2) i'll get an error when the jsp try's
to open a domino session.

----Schnipp ----
org.apache.jasper.JasperException: Notes initialization failure - err

org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
	at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241)

Has anybody ever seen this failure or even better find a solution for
this?
By the way, my domino server is Release 6.0.1 CF1 and the JDK tomcat is
running with is 1.4

any help is welcome
