Invalid URL Pattern exception when deploying ear file

Question

Hi,
I encountered some problem during deploying an ear file into SJSAS PE. This ear file has successfully been deployed into WebLogic Server and works fine.
The error message is as follows:
Deploying application in domain failed; Error loading deployment descriptors for module [wsgServerRel1_0] -- Invalid URL Pattern: [pfk/PfkMainServlet] Error loading deployment descriptors for module [wsgServerRel1_0] -- Invalid URL Pattern: [pfk/PfkMainServlet] The following is the relevant part regarding URL pattern:
     <servlet>
          <servlet-name>PfkMainServlet</servlet-name>
          <servlet-class>com.sns.pfk.servlet.PfkMainServlet</servlet-class>
          <load-on-startup>0</load-on-startup>
     </servlet>
     <servlet-mapping>
          <servlet-name>PfkMainServlet</servlet-name>
          <url-pattern>pfk/PfkMainServlet</url-pattern>
     </servlet-mapping>What else I need to do to make it work?

Answer 1

You have an error in your url-pattern. A url-pattern must either begin with a slash ("/") for the exact match or directory match or it could begin an asteric("*") for the extension match(refer to the servlet spec).
In your case it should be something like:
<servlet-mapping>
          <servlet-name>PfkMainServlet</servlet-name>
          <url-pattern>/pfk/PfkMainServlet</url-pattern>
</servlet-mapping>
or
<servlet-mapping>
          <servlet-name>PfkMainServlet</servlet-name>
          <url-pattern>/pfk/*</url-pattern>
</servlet-mapping>
