问题 I have created an index.html file for a Java (.war) application that I deployed on tomcat. I already have a Java Servlet file that queries a remote db server for a picture i stored there. The java servlet file is called ImageServlet.java. I need the HTML page to display that image that the ImageServlet.java queries.
