如何在Java EE 7应用程序中设置上下文根

Question

I've seen this link and this one but I can't find the sun-web.xml anymore. I am going through the java ee 7 tutorial, specifically the hello1 application. I don't understand how the application knows that /hello1 is the context root, I mean, I don't see it specified anywhere in the web.xml file under /WEB-INF/web.xml . How does glassfish know, and how can we change it to, perhaps, /abc for example.

Answer 1

By default, context root is the same as package name.

If you use wildfly or jboss, you can add jboss-web.xml to webapp/WEB-INF/ to change context root, content like:

<?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>yourownroot</context-root>
</jboss-web>
