Hi I don't have a lot of experience that's why I'm here to ask some help. I get a String from the server which contains HTML to display. It works well but I need to display pictures sometimes (like img src="./images/mypic.jpg"/>).

So I decided to load every picture I need to display from the server and to save them into a folder that can be opened when HTML is read. I don't know how to do it, I tried to save pictures with this path : Executions.getCurrent().getDesktop().getWebApp().getRealPath("/")

But question is still how can I find my pictures ?

Thank you

EDIT : SOLUTION

I found a solution : When I create my file, I use this method :

public void saveAsFile() {
    try {
        BufferedImage pic = ImageUtils.decodeToImage(this.getImage());
        String path = Executions.getCurrent().getDesktop().getWebApp().getRealPath("/ressources/");


        File outputfile = new File(path.replaceAll("\\\\", "/") + "/pics/tmp/" + this.getNom_image());

        ImageIO.write(pic, "jpg", outputfile);
    } catch (IOException e) {
        System.out.println(e.getMessage());
    }
}

Then my picture can be created in webapp resources folder. And when I read the content of my HTML, I replace src with this expression :

contentHTML = contentHTML.replaceAll("src=\"./images/","src=\"./ressources/pics/tmp/");

It works on local and when I access to my computer with my tablet on web browser.

Don't know if it is the best way of doing it, but it works for now.

Thank you
