I have created a JSP page and from this page i will invoke a servlet and process something and redirect back to same JSP.
But when i deploy only JSP all is fine. But when i include my servlet in a project tomcat 8 fails to start and it throws below error.

I defined my web.xml in following way

<servlet-mapping>
<servlet-name>SolrServlet1</servlet-name>
<url-pattern>SolrServlet1</url-pattern> </servlet-mapping> </web-app>
Please help me to resolve this
If I look at your error logs, it says it is caused by
java.lang.IllegalArgumentException: Invalid <url-pattern> SolrServlet1 in servlet mapping
Please use /SolrServlet1
instead of SolrServlet1
(basically prepending a forward slash) in your url-pattern and check the results.
The url-pattern specification:
- A string beginning with a ‘/’ character and ending with a ‘/*’ suffix is used for path mapping.
- A string beginning with a ‘*.’ prefix is used as an extension mapping.
- A string containing only the ’/’ character indicates the "default" servlet of the application. In this case the servlet path is the request URI minus the context path and the path info is null.
- All other strings are used for exact matches only.
