Jetty configuration: problems with MySQL JNDI

问题

The Jetty embedded has a jetty.xml for the configuration. This configuration has a mysql jndi-connection.

When I run jetty with gradle, it throws an exception:

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource
at org.eclipse.jetty.util.Loader.loadClass(Loader.java:86)

at com.sahlbach.gradle.plugins.jettyEclipse.JettyEclipseRun.startJetty(JettyEclipseRun.groovy:318)

This is the line of jetty.xml where the exception is thrown:

<New id="relevante" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg></Arg>
    <Arg>jdbc/Relevante</Arg>
    <Arg>
        <New id="relevanteDataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource">
           <Set name="url">jdbc:mysql://localhost:3306/xxxx</Set>
           <Set name="user">xxxx</Set>
           <Set name="password">xxxx</Set>
        </New>
     </Arg>
</New>

The MySQL connector is a dependency of gradle and I don't know if I need to place the connector into a local address (in addition to as dependency in gradle).

jettyEclipse {
     additionalRuntimeJars = files( new File("$rootDir/src/main/webapp/WEB-INF/lib/mysql-connector-java-5.0.8-bin.jar") )
     warFile = file("$rootDir/build/libs/relevanteme.war")  
     jettyConfig = file("$rootDir/jetty.xml")
     contextPath = ""
     automaticReload = "true"
     scanIntervalInSeconds = 5
     webDefaultXml = file("$rootDir/webdefault.xml")
}

Thanks!!

回答1:

What's the task to run jetty? Do you know if there is a separate configuration for that and does it extends from compile?

回答2:

The solution's to have two xml files for server configuration. One of these two files will be jetty.xml which will have all the server configuration. The other file will be jetty-env.xml with webApp configuration and connection to the database (this file has to be in webapp/WEB-INF/).
