Help web services and tomcat

[humz]

Hi I was hoping someone could shed some light on the following error:

java.lang.NoClassDefFoundError: org/apache/tools/ant/BuildException
org.apache.jasper.JspCompilationContext.createCompiler(JspCompilationContext.java:197)
org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:508)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:295)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:292)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)
javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

It occurs when I click the list button on http://localhost:8080/soap/admin/

Thanks

I think you should... add the Ant jars to the common/lib in Tomcat
