Hi, I have written a servlet and an applet, the applet opens an url socket to the servlet which loads the applet. I have tested my servlet-applet with JavaWeb Server and it works, but when I tried to run the servlet with apache-tomcat, my web server run the servlet and it loads the applet, but when applet tries to open the url connection to the servlet, it gives the following exception. java.io.FileNotFoundException: http://www.yfas.com.tr/servlet/servlet/Login at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getHeaderField(Unknown Source) at sun.plugin.protocol.jdk12.http.HttpURLConnection.checkCookieHeader(Unknown Source) at sun.plugin.protocol.jdk12.http.HttpURLConnection.getInputStream(Unknown Source) at LoginApplet.validateUser(LoginApplet.java:238) at LoginApplet.handleEvent(LoginApplet.java:133) at java.awt.Component.postEvent(Unknown Source) at java.awt.Component.postEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEvent(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) The codes in the applet to connect the servlet is as follows: String urlString = "http://" + getDocumentBase().getHost() + "/servlet/servlet/Login"; java.net.URL url = new java.net.URL(urlString); I want to wonder that tomcat whether loads the Login servlet at startup, I have added the following entry into web.xml file: <servlet> <servlet-name>Login</servlet-name> <servlet-class>LoginServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> Is there any mistake in the url of the servlet? I have written the url of the servlet in the address bar of the browser as http://www.yfas.com.tr/servlet/servlet/Login and the servlet runs, so, I have written this address into the appet as indicated above. Is there any idea? Deniz...
