Jetty 9 Maven plugin and JNDI with No Suitable Constructor

Question

I'm trying to get JNDI resource creation to work with the Jetty 9 Maven plugin. The same configuration works correctly with Jetty 8 but yields an java.lang.IllegalStateException: No suitable constructor with Jetty 9. Here are the relevant files:

pom.xml:

<?xml version="1.0"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0

      <artifactId>hsqldb</artifactId>

    </dependency>
  </dependencies>
</project>

src/test/resources/jetty-ds-dev.xml:

<?xml version="1.0"?>
<Configure id="Server" class="org.eclipse.jetty.webapp.WebAppContext">
  <New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">

    <Arg>
      <New class="org.hsqldb.jdbc.JDBCDataSource">
        <Set name="DatabaseName">mem:foo</Set>
        <Set name="User">SA</Set>
      </New>
    </Arg>
  </New>
</Configure>

and the actual error:

                        <New class="org.hsqldb.jdbc.JDBCDataSource">
                                <Set name="DatabaseName">mem:foo</Set>
                                <Set name="User">SA</Set>
                        </New>
                </Arg>

Change the comment two lines down (to restore Jetty 8) and the application launches correctly.

Answer 1

You need the following line in your jetty-ds-dev.xml file as the 2nd line:

<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://www.eclipse.org/jetty/configure_9_0.dtd">

Not sure why it worked with 8 without having the configure.dtd specified, but definitely should be there, and at version 9_0.
