[vtp-dev] execute java code in jar from script module

Discussion:

2012-06-14 12:37:00 UTC

I am trying to inclode java code developped in external project as a
jar in dependencies folder.
But when executing the script the classes and methods in in jar are
not available.
Is it possible to execute code developped in other java projects from
the script module? How is it done?

Thanks.

Toni

Code in DemoTools.jar
--------

import java.util.Date;

public class Demo {
public void date(){
Date d = new java.util.Date();
System.out.println("date: " + d);
}

public static void main(String [ ] args)
{
Demo d = new Demo();
d.date();
}
}

Code in the script module
-------------------------------
var d = new java.util.Date();
Log.info('date: ' + d);

var d2 = new DemoTools.Demo();
d2.date();

Error in Tomcat logs
-------------------------------

Toni,

To access the classes in your jar file simply address them using the fully
qualified class name like you did for java.util.Date. It doesn't appear
that Demo is in the DemoTools package so that line should look like:

var d2 = new Demo();

Is dependencies folder the correct place to put my DemoTools.jar where
he Demo.class is defined?

It sure is. You might try using the special namespace Packages.Demo.

Sorry I am trying to include the Demo.java in a package namespace like
demotools or Demo, but I still get similar errors, the name of the
package is reported as not defined.
I have verified that my jar is deployed in the war inside

webapps\Demo2\WEB-INF\eclipse\plugins\Demo2.e19222ebb03d4b17aa7af744a233baec_0.0.0\project\Dependencies\DemoTools.jar

inside the jar there my class Demo as
Demo.Demo.class or demotools.Demo.class (I have tryied both)

It sure is. You might try using the special namespace Packages.Demo.

The form worked for me in our lab:

d.date();
