Bingo! It can't!
{BTW, it shouldn't be org.jasper.xxxxx, as that's Paul Jasper's site,
whoever he is}
What should be happening with JspC [and in the JspServlet IMO] is:
/hello.jsp => org.apache.jsp.hello_jsp in {output}/hello_jsp.java
/subdir/hello.jsp => org.apache.jsp.subdir.hello_jsp in
{output}/subdir/hello_jsp.java
with the resultant web.xml fragment:
<servlet>
<servlet-name>org.apache.jsp.hello_jsp</servlet-name>
<servlet-class>org.apache.jsp.hello_jsp</servlet-class>
</servlet>
<servlet>
<servlet-name>org.apache.jsp.subdir.hello_jsp</servlet-name>
<servlet-class>org.apache.jsp.subdir.hello_jsp</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>org.apache.jsp.hello_jsp</servlet-name>
<url-pattern>/hello.jsp</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>org.apache.jsp.subdir.hello_jsp</servlet-name>
<url-pattern>/subdir/hello.jsp</url-pattern>
</servlet-mapping>
Then they can be compiled by an ordinary <javac> ant task, and warred and
deployed in any servlet container.
Now, why might you want to do this?
The resultant WAR file can be put into a container that doesn't have JSP or
tools.jar support. It's great for embedded applications. Much lower
overhead, and more predictable response. It's also great for QA. You test
exactly the bits that get shipped.
