Need to know what kind of values and how to pass them to Map<String String>

[Matt Kohanek]

I have a Device class under my DeviceCOntainer package that declares a map and then the setter and getter for it like so:

  @ElementMap(entry = "property", key = "name", attribute = true, inline = true, required=true, data=false, empty=true) 
    private Map<String, String> properties;

public Map<String, String> getProperties() {
		return properties;
	}

	public void setProperties(Map<String, String> properties) {
		this.properties = properties;
	}  

Then I have an App class also under the DeviceContainer package where I am trying to set the values for this Map. Like this:

  Device device = new Device();
device.setProperties(null);  

I get no errors when I leave null between the ( ), but I am trying to add this to a web service and there has to be a value there. I have tried putting many diferent things between the ( ), such as ("property1", "property2"), (String "property"), (Map<"property1", "property2">) and many other variations, but I always get errors. So if I am wanting to just set this to a simple string or set of strings, what is the correct syntax to do so? I have never worked with the Map class, so I am readng up on it now, but I wanted to go ahead and post this now in case I am unable to figure it out on my own. That way hopefully there will be an answer here by the time I get through with the reading. Im guessing this is a pretty simple problem for most of the vets here.

Thanks

You need to create a Map<String,String> object, add all properties, and then use that object as your parameter.

So I would create this as its own class under the DeviceContainer package? Something like

class DeviceProperties{
String property1;
String property2;

}


Then in the App classs I would need to do:

DeviceProperties properties = new DeviceProperties;

device.setProperties(properties);


But that still leaves each property blank, so I suppose I would need setters in getters in the new DeviceProperties class right? Is this about right, or is there an easier way to go about it?


edit - Im guessing I would need to use put(Object key, Object value) which is something Ive been reading about while looking into the map class right?

I was more thinking this:

Map<String,String> properties = new HashMap<String,String>();
properties.put("property1", "value1");
properties.put("property2", "value2");
properties.put("property3", "value3");
device.setProperties(properties);

Thanks man, your the greatest, exactly what I was needing. Works perfectly.

At least I was on the right track when I guessed I would need to use put () x-P

You guys should get a donation link going, I know they do that at cybertechhelp.com, and I donate every year, because just like this site, I get tons of great help.

Thanks again for the great info

What makes you think we don't already have such a link?

And thank you for the kind remarks about us

[Matt Kohanek]

Thanks, I looked around a bit for it but couldnt find one.

As soon as I get paid in a couple of weeks you are going to see my status changed to "gravedigger"

unless I change my mind about which one to choose between now and then x-)

[Matt Kohanek]

So um, how do I go about changing my status to something of my choosing? I made the donation but I havent been presented with the option to do so

That last sort of question is usually discussed on the "Ranch Office" forum.
