Spring Batch Admin UI with Grails?

[AnthonyRyan]

Hey mminella,

I generated the web.xml using the install-templates command. It's at src/war/web.xml

The only other servlet mapping in there besides the one I put in for my batch servlet is the gsp one. There doesn't seem to be any for the grails servlet:

    <servlet-mapping>
        <servlet-name>gsp</servlet-name>
        <url-pattern>*.gsp</url-pattern>
    </servlet-mapping>

The actual servlets are defined above it then:

    <!-- Grails dispatcher servlet -->
    <servlet>
        <servlet-name>grails</servlet-name>
        <servlet-class>org.codehaus.groovy.grails.web.servlet.GrailsDispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <!-- The Groovy Server Pages servlet -->
    <servlet>
        <servlet-name>gsp</servlet-name>
        <servlet-class>org.codehaus.groovy.grails.web.pages.GroovyPagesServlet</servlet-class>
    </servlet>

Maybe I should add one for the grails servlet? A simple "/"? But I woulda thought my Batch pattern of "/batch/*" would still work.

I'll add in another mapping and see what happens. If you think of anything else, let me know, and thanks for your help so far, too.

I added in the following servlet mapping to the web.xml:

        <servlet-mapping>
		<servlet-name>grails</servlet-name>
		<url-pattern>/*</url-pattern>
	</servlet-mapping>

Now it doesn't seem to be going to /grails-app/views/ anymore but I still get a 404 just saying that "the requested resource () is not available" when I hit any of the links at the top of the batch admin pages:

<li><a href="/myapp/batch">Home</a></li>
<li><a href="/myapp/batch/jobs">Jobs</a></li>
<li><a href="/myapp/batch/jobs/executions">Executions</a></li>
<li><a href="/myapp/batch/files">Files</a></li>

So it's like the pages are actually missing.

Does anyone know what page it should redirect to when it goes to, say: /myapp/batch/jobs? Like, is it /myapp/batch/jobs/index.jsp? Or /myapp/batch/jobs/home.jsp?

What's also strange is that if I go to /myapp/batch I get a 404 (this is the "Home" link above), but /myapp/batch/ works fine!

Cheers,

I turned on extra logging and it does look like the grails servlet is still having an effect.

Here is the stack trace for the sample batch admin project when the jobs page is rendered correctly:

And here is the output from myapp when I try to access the jobs page. Note that the Freemarker output is looking for a view with name 'null' now instead of a view with name 'jobs':

It is trying to render /WEB-INF/grails-app/views/jobs.jsp (even tho the servlet mentioned is the Batch Servlet and not the grails one) instead of the normal jobs.ftl freemarker layout page.

I think I'm close to giving up on this. Btw, I also explicitly added freemarker version 2.3.19 to my buildconfig but no dice.
