New folder inside an existing plugin

[Marco Rossi]

Hi all,

I am extending org.eclipse.wst.xml.ui and I have created a "properties" folder which contains, of course, some properties file I need during execution.

This "properties" folder is at the root of the plugin, but how can I access to it?
I mean, which is the path?

"./properties"? I tried but it seems not working.

Thanks
Marco

If the properties file is inside your source you can use

URL url = Trial.class.getResource("a.properties");

[Marco Rossi]

For example:

my source code is in the folder org.eclipse.wst.xml.ui which contains some of classes for default XML Editor inside Eclipse.

I have added org.eclipse.wst.xml.ui/properties.

So, I will try with your code but, what is "Trial"?

Thanks
Marco

Trial can be any of your custom class where you wish to refer the .properties file.

Therefore is it the name of the class where I am calling the properties file from?

Not necessarily be. But please try and let us know if you were able to access the .properties file. It can be any class present in your source file.

Ok, thanks.
I will try tomorrow at work, not I am at home

I will write tomorrow.

Thanks

It seems not working...I explain better what I am doing.

I have Test1.java whose path is /org/eclipse/wst/xml/ui/internal/contentassist/Test1.java

Here I am trying to load a file which is in the root of my plugin inside folder /properties.

I tried with

xmlFile = this.getClass().getResource("/xml/example.xml");
		
		System.out.println(xmlFile.getPath());
		
		if(new File(xmlFile.getPath()).exists()) {
			xpr = new LoadXML(xmlFile.getPath());
		}
		else {
			logManager.log("No file defined");
		}

but I get a NullPointerException

Thanks
Marco

You are not supposed to use the Class and resource to load from a Plugin. An Eclipse plugin is a bundle and lives in a Context of an OSGi-instance. Hence, you need to use the Bundle and Context.

Bundle bundle = Platform.getBundle("se.lime.example.readfile");
URL fileURL = bundle.getEntry("files/test.txt");
File file = null;
try {
    file = new File(FileLocator.resolve(fileURL).toURI());
} catch (URISyntaxException e1) {
    e1.printStackTrace();
} catch (IOException e1) {
    e1.printStackTrace();
}

Of course, if you are in the bundle you want to read from, you can get the Bundle from the current Context.

Alternatively you can also use URL directly.

URL url;
try {
        url = new URL("platform:/plugin/se.lime.rcp.plugin.filereader/files/test.txt");
    InputStream inputStream = url.openConnection().getInputStream();
    BufferedReader in = new BufferedReader(new InputStreamReader(inputStream));
    String inputLine;
 
    while ((inputLine = in.readLine()) != null) {
        System.out.println(inputLine);
    }
 
    in.close();
 
} catch (IOException e) {
    e.printStackTrace();
}

This works fine.

Thanks a lot

Too difficult for "beginning". Moving thread.
