    copied!<p>I've been working on a program to extract information from a dynamic web application, and the program worked fine until I set my tomcat server to use SSL using a self-signed(thus, untrusted) certificate. The stack trace of the error is:</p> <pre><code>javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target Error: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Alerts.java:150) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1584) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:174) at com.sun.net.ssl.internal.ssl.Handshaker.fatalSE(Handshaker.java:168) at com.sun.net.ssl.internal.ssl.ClientHandshaker.serverCertificate(ClientHandshaker.java:848) at com.sun.net.ssl.internal.ssl.ClientHandshaker.processMessage(ClientHandshaker.java:106) at com.sun.net.ssl.internal.ssl.Handshaker.processLoop(Handshaker.java:495) at com.sun.net.ssl.internal.ssl.Handshaker.process_record(Handshaker.java:433) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:877) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1089) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1116) at com.sun.net.ssl.internal.ssl.SSLSocketImpl.startHandshake(SSLSocketImpl.java:1100) at sun.net.www.protocol.https.HttpsClient.afterConnect(HttpsClient.java:402) at sun.net.www.protocol.https.AbstractDelegateHttpsURLConnection.connect(AbstractDelegateHttpsURLConnection.java:170) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:857) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getOutputStream(HttpsURLConnectionImpl.java:230) at com.certicom.gls.glscs.nongui.URLReader$PostURL.setupURL(URLReader.java:34) at com.certicom.gls.glscs.nongui.URLReader.getLogin(URLReader.java:227) at com.certicom.gls.glscs.nongui.URLReader.testLogin(URLReader.java:436) at com.certicom.gls.glscs.nongui.Controller.loginMenu(Controller.java:384) at com.certicom.gls.glscs.nongui.Controller.menu(Controller.java:324) at com.certicom.gls.glscs.nongui.Controller.&lt;init&gt;(Controller.java:49) at com.certicom.gls.glscs.nongui.Controller.main(Controller.java:61) </code></pre> <p>In a web browser, the user is prompted a warning when accessing a HTTPS site with an untrusted certificate, and asked to make an exception if he likes to proceed; I would like to implement a similar functionality for my command-line application... I admit that I am new to socket programming and networking in general; any advice solving this problem will be great!</p>
