problem with running Servlet on Tomcat: InvocationTargetException
- by Fahim
Hi,
I am new to Tomcat, and trying to run a simple HelloWorld servlet. I have installed Tomcat 6, and Jdk1.6 on Mandriva Linux, set CLASSPATH and JAVA_HOME. I have the following files and directories:
$CATALINA_HOME/webapps/MyApp/WEB_INF/classes/TestServlet.class
$CATALINA_HOME/webapps/MyApp/WEB_INF/web.xml
My web.xml file contains the following:
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5"
<description>ZibJana Localization</description>
<display-name>ZibJana Localization</display-name>
<!-- Define the servlets for this application-->
<servlet>
<servlet-name>ZibJana</servlet-name>
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>ZibJana</servlet-name>
<url-pattern>*</url-pattern>
</servlet-mapping>
But when I try to invoke my servlet with url http://localhost:8080/MyApp, tomcat fails to launch launch the servlet. I checked in the $CATALINA_HOME/logs/catalina.out log-file and found the following error, which occurs every time I start tomcat service.
INFO: Deploying web application directory MyApp

SEVERE: End event threw exception
java.lang.reflect.InvocationTargetException

at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
Please let me know where my mistake is.
Thanks in advance.
