web module servletpath

[jokoul webster]

Hi Phil:

       If I wanna write some jsps in WebModule1(Which is as same level as WebModule2) and wanna invoke some atcions which are in WebModule2,how to set the link in jsp? For Example,

       1:if the jsp is embedded in Host module,then "<a href="WebModule2/action">xxx</a>" is right,I have tried it successfully;

       2:if the jsp is within the WebModule2,then "<a href="../WebModule2/action">xxx</a>" is right,I have tried it successfully;

       3:if the jsp is within the WebModule1,then neither "<a href="WebModule2/action">xxx</a>"  nor "<a href="../WebModule2/action">xxx</a>" is right,and if the value is"<a href="${request.contextPath}/WebModule2/action">xxx</a>" ,the request.contextPath is empty,how to handle it?

      

Thanks

You should be able to refer to the JSP using a relative URL from any
other page. It is just a question of making sure that the relative URL
reflects the relative locations of the referring action/page, and the
target page.

I've now added an additional option into the "to-module" attribute,
which I think makes things a bit easier and more intuitive when
dealing with JSPs.

In the web frameworks example, there is now a JSP-only module which
has the following Spring definition:

<web:mapping>
<web:to-module prefix = "/jsp" setContextPath="true"/>
<web:to-handler extension = "jsp" servletName="jspServlet"/>
<web:to-handler extension = "gif" servletName="jspResources"/>
<web:to-handler extension = "css" servletName="jspResources"/>
</web:mapping>

<web:servlet id = "jspResources"
servletClass = "org.impalaframework.web.servlet.ResourceServlet"/>

<web:jsp-servlet id="jspServlet"/>

The setContextPath attribute means that requests which are mapped to
the module using the '/jsp' prefix will have the context path
(HttpServletRequest.getContextPath()) equal to the application path
plus /jsp (e.g. /webframeworks/jsp).

In this case, the URL:

http://localhost:8080/webframeworks-host/jsp/hello.jsp

is mapped to hello.jsp, which is in the 'default' package in
webframeworks-jsp module's classpath.

For resources, this works similarly. The stylesheet

http://localhost:8080/webframeworks-host/jsp/css/style.css

is mapped to style.css, contained within the 'css' package.
