Re: Fetching images for users: where to put them?

[Matias Costa]

In web.xml:

<servlet>
    <servlet-name>imageReceiver</servlet-name>
    <servlet-class>xxx.ImageReceiver</servlet-class>
    
    <init-param>
        <param-name>imagePath</param-name>
        <param-value>/the/place</param-value><!-- or C:\the\place -->
    </init-param>
</servlet>

And in the servlet:

public void init(ServletConfig servletConfig) throws ServletException{
    imagePath = servletConfig.getInitParameter("imagePath");
    if (!imagePath.endsWith(File.separator)) imagePath += File.separator
    try {
        File imageFolder = new File(imagePath);
        if (!File.exists()) Util.mkdirRecursive(imagePath);
    } catch ... whatever you want to do if something fails
  }
