<url-pattern> confusion

[Ahmed Bin S]

Hello,

I am creating my first servlet (well, technically I am not, as I did this stuff in 2010 but as I have forgotten it all, for all intents and purposes I am!).

I am creating it using the New Dynamic Web Project in Ecplise (and am using Wildfly 10).

My deployment descriptor is below, and my application is LearningServlets.jar. What I would like is to map the servlet to a URL that doesn't have LearningServlets in it i.e. localhost:8080/Intro, and not localhost:8080/LearningServlets/Intro.
I tried hardcoding the entire URL in but it didn't work. Any ideas would be appreciated.

Thank you.

That's not the way things work by default. A servlet container will usually requires that the first thing in the URL path be the context path, in your case /LearingServlets.

In Tomcat, you can make the application the ROOT web context and the context path will simply be /.

I have no idea how to make that happen running in an IDE (which I do not do).

Ah, great, thanks. Will look into context root for Wildfly.

PS, is there a reason you shun IDEs?

[Ahmed Bin S]

Thanks, you were right, I had to set the context-root to /.

For Wildfly, this can be done by creating a jboss-web.xml file under WEB-INF, and adding the following:

<?xml version="1.0" encoding="UTF-8"?>
<jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="
http://www.jboss.com/xml/ns/javaee
http://www.jboss.org/j2ee/schema/jboss-web_5_1.xsd">
<context-root>/</context-root>
</jboss-web>

I use my IDEs as smart editors. What I don't do is to run the servlet container in the IDE because it adds extra complexity and doesn't adequately mimic the real-world environment that the app will eventually run in. I run my own separate instances of the servlet container.

Ah, thanks for clarifying - that makes perfect sense.
