Project: Tomcat Category: Bug Report SubCategory: New Bug Report Class: support State: received Priority: high Severity: critical Confidence: public Environment: Release: jakarta-tomcat-4.0-m4 JVM Release: JDK-1.2.2_005 Operating System: Solaris OS Release: 2.7 Platform: Sun Ultra Synopsis: java.lang.NullPointerException with jakarta-tomcat-4.0-m4 Description: I am using a third party software package by a company called Tom Sawyer. It is a topology engine, and can be used in a servlet environment. It works in the following way. You create a graph that represents a network, which is composed of nodes (such as servers and storage devices) and edges (connections between the nodes). You can then apply different layouts to the graph, such as circular or hierarchical. I installed and configured jakarta-tomcat-3.2, as well as the Tom Sawyer software on my system, and it works correctly. However, when I try it with jakarta-tomcat-4.0-m4, I get get several errors, as shown below in the output from catalina.out, localhost_log.2000-12-12.txt, and from the Tom Sawyer program as well, which is called Tomahawk. I made sure that environment for both the 3.2 and 4.0 was set up correctly, as shown under Additional Environment Description. The reason we want to use 4.0 is because it has struts, while 3.2 does not. If you have any ideas on how to solve this problem, or when 4.1 might be available, please let me know.

- Synopsis:
- java.lang.NullPointerException with jakarta-tomcat-4.0-m4
- Environment: (jvm, os, osrel, platform)
- JDK-1.2.2_005, Solaris, 2.7, Sun Ultra
- Additional Environment Description:
- wiseguy 152 =>echo $PATH /files/jbuilder/jdk1.2.2/gltj-1.0/lib/sparc-sunos5:/files/java/jdk1.2.2/bin:/fil es/jbuilder/jdk1.2.2/src:/files/jbuilder/jdk1.2.2:/files/jbuilder/jdk1.2.2/jni:/ usr/local/bin:/usr/java1.2/bin:/home/ejamison/bin:/usr/ccs/bin:/usr/dist/pkgs/de vpro/5.x-sparc/bin:/usr/openwin/bin:/usr/dt/bin:/usr/dist/svr4/bin:/usr/dist/loc al/bos/exe:/usr/dist/local/exe:/usr/dist/exe:/usr/bin:/usr/etc:/usr/sbin:/usr/uc b:. echo $CLASSPATH .:/files/jbuilder/jdk1.2.2/src.jar:/usr/java1.2/jre/lib/ext: Likewise the tomcat_home was set correctly as well: wiseguy 140 =>echo $TOMCAT_HOME /files/jakarta-tomcat-4.0-m4 and I was using the same version of Java: wiseguy 141 =>echo $JAVA_HOME /files/java/jdk1.2.2 wiseguy 142 =>java -version java version "1.2.2" Classic VM (build JDK-1.2.2_005, green threads, sunwjit) The only slight difference that I noted was that for 4.0 was that it required this line in the web.xml file: Which the 3.2 version did not seem to like. I am not sure if this could be related to the error message I was getting though.
- Report Description:
-
I am using a third party software package by a company
called Tom Sawyer. It is a topology engine, and can be used
in a servlet environment. It works in the following way. You
create a graph that represents a network, which is composed
of nodes (such as servers and storage devices) and edges
(connections between the nodes). You can then apply different
layouts to the graph, such as circular or hierarchical.
I installed and configured jakarta-tomcat-3.2, as well
as the Tom Sawyer software on my system, and it works
correctly. However, when I try it with jakarta-tomcat-4.0-m4,
I get get several errors, as shown below in the output
from catalina.out, localhost_log.2000-12-12.txt, and
from the Tom Sawyer program as well, which is called
Tomahawk. I made sure that environment for both the 3.2
and 4.0 was set up correctly, as shown under Additional
Environment Description. The reason we want to use 4.0 is
because it has struts, while 3.2 does not. If you have any
ideas on how to solve this problem, or when 4.1 might be
available, please let me know. Thanks Eric Jamison
