How a plugin method can return a (javascript) properties object

[gobie]

Hi,

With VC0 4.1, I have a plugin method written in Java. I would like this method to return an object that Orchestrator (VCO) will see as a javascript properties object, directly without going through serialization or other processing...

To do so:

- What class of java object my plugin method should return?

- what do I use as return-type attribute when declaring my method in the VSO.xml file?

<method script-name="myMethod" java-name="myMethod" return-type="????">

Thanks in advance.

Hi Arnaud,

Your Java method should return a java.util.Properties (or java.util.Hashtable) object.

And your vso.xml file declaration should look like:

<method script-name="myMethod" java-name="myMethod" return-type="Properties">

I hope it helps.

Hi Sergio,

Thanks for your answer.I gave it a try but my method still does not seem to return a Javascript Properties.

I wrote my method so that it returns a java.util.Properties :

public Properties getInfosInProperties() {
        Properties retMap = new Properties();

        retMap.put("key1", "valeur 1");
        retMap.put("key2", new Long(2));
        retMap.put("key3", true);

        return retMap;
    }

And I described it in the vso.xml :

<method script-name="getInfosInProperties" java-name="getInfosInProperties" return-type="Properties">

But I do not get a Properties object when I call it from a Javascript action in VCO :

Here is a test script

[...]

var map = myServiceFromMyPluggin.getInfosInProperties();

var className = System.getObjectClassName(map);
var pluginName = System.getObjectPluginName(map);
var type = System.getObjectType(map);

System.log("class name : " + className);
System.log("plugin name : " + pluginName);
System.log("type : " + type);

Here is what I get in the log:

[2012-03-15 10:29:45.125] [I] class name : Object
[2012-03-15 10:29:45.125] [I] plugin name : Server
[2012-03-15 10:29:45.125] [I] type : null

I should have got the following log if the returned object was a javascript Properties.

[2012-03-15 10:52:47.179] [I] class name : Properties
[2012-03-15 10:52:47.179] [I] plugin name : Server
[2012-03-15 10:52:47.179] [I] type : Properties

Hi Arnaud,

You're right, the object that your method returns must be Hashtable actually (I was thinking that Properties should be valid also since it extends Hashtable).

Try with:

public Hashtable<String, Object> getInfosInProperties() {
    Hashtable<String, Object> retMap = new Hashtable<String, Object>();

    retMap.put("key1", "valeur 1");
    retMap.put("key2", new Long(2));
    retMap.put("key3", true);

    return retMap;
}

The vso.xml file is fine with "Properties". And you'll get a Properties scripting object from the vCO scripting API.

I hope it helps.

Hi Sergio,

It works! This is great. You saved me hours.

Thank you!

Hi!

Thank you both for this great thread! I think it can save other people hours of time, too

Could please a forum moderator COPY this thread to the Orchestrator Plugin section
