Java – ServletContext getresource does not work

I tried to use ServletContext Getresource to retrieve the Java net. URL reference (then I'll include it in the PDF library using iText)

Example 1:

String picture = ServletContext.getRealPath("picture.jpg");
// picture contains a non-null String with the correct path
URL pictureURL = ServletContext.getResource(picture);
// pictureURL is always null

Example 2:

URL pictureURL = ServletContext.getResource("picture.jpg");
// pictureURL is always null

Then build a Java. Net file that points to the files in my webapps / folder net. What is the correct method for URL objects? Why does getrealpath work but not getresource?

In case of help, here is my folder structure

webapps -> mySite -> picture.jpg

My pictures need to be stored in WEB-INF or WEB-INF / classes before they can be read by getresource?

Solution

Therefore, you must provide a full path relative to the context For example:

URL pictureURL = servletContext.getResource("/images/picture.jpg");

(note the ServletContext variable below)
