*Hello, I use Tomcat 6. Tomcat works very well.* *I download: "OWL-S/UDDI Matchmaker version 1.3" and I followed the steps in this link: * http://www.cs.cmu.edu/~softagents/atlas/matchmaker/inst-mm.htm *But, my problem: when I modify the the "config.properties" file and I install the Matchmaker ie: In the installation directory type the following command on the command line:"ant install-juddi-matchmaker". **It gives me:* *install-juddi-matchmaker: BUILD SUCCESSFUL* *But the problem: Tomcat can not work and it gives me this error:* java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Caused by: java.lang.NullPointerException at org.apache.catalina.startup.Catalina.await(Catalina.java:642) at org.apache.catalina.startup.Catalina.start(Catalina.java:602) ... 6 more java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.apache.catalina.startup.Bootstrap.start(Bootstrap.java:288) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:413) Caused by: java.lang.NullPointerException at org.apache.catalina.startup.Catalina.await(Catalina.java:642) at org.apache.catalina.startup.Catalina.start(Catalina.java:602) ... 6 more
