we will look at two ways to register a Java Servlet in Jakarta EE — one using aweb.xmlfile, and the other using annotations. Then we’ll register servlets in Spring Boot using XML configuration, Java configuration, and through configurable properties. ...
If enabled, Tomcat will send information such as the Servlet and JSP specification versions and the full Tomcat version, among others. This gives attackers a workable starting point to craft an attack. To prevent this information leakage, disable the xpoweredBy attribute in the server.xml file....
It does this by reading the testProgressListener object that was placed in the session by TestServlet. It calls the getMessage() method on the testProgressListener object and outputs this to the response. ProgressServlet.javapackage test; import java.io.IOException; import java.io.Pr...

Thepurpose of the main method in Javais to be a program execution start point. When you runjava.exe, thenthere are a couple of Java Native Interface (JNI) calls. These calls load the DLL that is really the JVM (that’s right –java.exeis NOT the JVM). JNI is the tool that we ...
Java servlet containers may be combined with other web servers to provide a more complete runtime environment for deployingJava-based web applications. Apache Tomcat also provides additional services such as security and resource management. Is Apache Tomcat a web server or an application server? In...
