Hello everybody! I have installed JDK1.4 and Tomcat 4.1.16 LE on a Windows 2000 machine.
To support SSL protocol in my servlet I use the version of JSSE API integrated in JDK 1.4: import javax.net.ssl.*; //package present in JDK 1.4 ... URL url = new URL(urlString); HttpsURLConnection Con = (HttpsURLConnection)url.openConnection(); .... in this way I receive this Exception when the servlet tries to connect to the https URL: java.lang.ClassCastException: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl If I change the code in this way: import com.sun.net.ssl.*; //package present in old JSSE 1.0.x API ... URL url = new URL(urlString); HttpsURLConnection Con = (HttpsURLConnection)url.openConnection(); .... all works correctly. This means that the servlet works if it uses "com.sun.net.ssl" package and not "javax.net.ssl". How come? I would like to use javax.net.ssl package because it is more up-to-date and it is that one integrated with JDK 1.4. Sincerely I don't know why Tomcat searchs for "com.sun.net.ssl package" and throws that Exception because I haven't installed in Tomcat old JSSE 1.0.x API!!! I found indications about this problem at: http://forum.java.sun.com/thread.jsp?thread=290800&forum=2&message=1146586 and at: http://java.sun.com/j2se/1.4/docs/guide/security/jsse/JSSERefGuide.html#Inst allProbs but they aren't very clear to me.... Is it possible that Tomcat uses internally old JSSE 1.0.x API?? HOW CAN I USE "javax.net.ssl" without having the "java.lang.ClassCastException"??? I hope someone can help me!! Thanks averybody in advance. Luca
