Installing Groovy
Install the groovy*.jar and asm*.jar files from the Groovy distribution in
the directory $RESIN_HOME/lib/groovy/:
$RESIN_HOME/ext-lib/groovy
$RESIN_HOME/ext-lib/groovy/groovy-1.0-beta-4.jar
$RESIN_HOME/ext-lib/groovy/asm-1.4.1.jar
$RESIN_HOME/ext-lib/groovy/asm-attrs-1.4.1.jar
$RESIN_HOME/ext-lib/groovy/asm-util-1.4.1.jar
The Groovy compiler groovyc compiles *.groovy files
directly to *.class files. With Resin classloader configuration
.groovy files are automatically compiled the same as .java files are:
resin.conf - Groovy for all web-apps
<web-app-default>
<class-loader>
<compiling-loader path="WEB-INF/classes"
compiler="groovyc"
source-extension=".groovy"/>
</class-loader>
</web-app-default>
resin-web.xml - Groovy for one web-app
<web-app>
<class-loader>
<compiling-loader path="WEB-INF/classes"
compiler="groovyc"
source-extension=".groovy"/>
</class-loader>
</web-app>
A Groovy Servlet
Since Groovy compiles to Java .class files, application can write servlets using groovy.
WEB-INF/classes/example/MyServlet.groovy
package example;
import javax.servlet.GenericServlet;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
public class MyServlet extends GenericServlet {
public void service(ServletRequest req, ServletResponse res)
{
out = res.getWriter();
out.println("Hello, world");
}
}
