Hi Janak,
the problem is solved.
Having yoiur hints and taking some extra-time for the problem, I realized
the the entries in the web.xml were not correct.
After correcting the web.xml everything works with Tomcat.
Here ist the corrected part of the web.xml.
<servlet>
<servlet-name>BApplet</servlet-name>
<servlet-class>com.ulcjava.container.servlet.server.ServletContainerAdapter</servlet-class>
<init-param>
<param-name>application-class</param-name>
<param-value>de.wb.b.application.BApplet</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>BApplet</servlet-name>
<url-pattern>/BApplet</url-pattern>
</servlet-mapping>
Mit freundlichen Grüßen
