Web application in other web application

Question

I am a student, I write final work at university, with Java EE I work half a year.

Below is what am looking for:

I need to create a web application (servlets/jsp) as a JAR file which can be added in another web application in WEB-INF/lib folder. And it should be made available by making an entry in web.xml file.

Can this be done?

If you use Servlet 3.0 you can please check the following question http://stackoverflow.com/questions/5013917/can-i-serve-jsps-from-inside-a-jar-in-lib-or-is-there-a-workaround — seenukarthi, May 09 '13 at 08:02

Of course you can do that:

1) Create Servlet classes / JSP files. Package them all in a jar file. Don't include web.xml or any other files.

2) Import the jar in your web application classpath.

3) Configure Servlet classes and JSP files in your web.xml as below:

For JSP:

<servlet>
    <servlet-name>MyJSPFile</servlet-name>
    <jsp-file>/path/to/jsp/MyJSP.jsp</jsp-file>
</servlet>

<servlet-mapping>
    <servlet-name>MyJSPFile</servlet-name>
    <url-pattern>/MyJSP.jsp</url-pattern>
</servlet-mapping>

For Servlet:

<servlet>
    <servlet-name>MyServlet</servlet-name>
    <servlet-class>my.servlet.classpath.MyServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>MyServlet</servlet-name>
    <url-pattern>/MyServlet.do</url-pattern>
</servlet-mapping>
