I am getting below mentioned exception while creating secure socket through https - ava.security.KeyStoreException: JKS at java.security.KeyStore.getInstance(KeyStore.java:203) at java.security.KeyStore.getInstance(KeyStore.java:130) at org.mortbay.jetty.security.SslSocketConnector.createFactory(SslSocketConnector.java:198) at org.mortbay.jetty.security.SslSocketConnector.newServerSocket(SslSocketConnector.java:407) at org.mortbay.jetty.bio.SocketConnector.open(SocketConnector.java:73) at org.mortbay.jetty.AbstractConnector.doStart(AbstractConnector.java:272) at org.mortbay.jetty.bio.SocketConnector.doStart(SocketConnector.java:147) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:39) at org.mortbay.jetty.Server.doStart(Server.java:233) at org.mortbay.component.AbstractLifeCycle.start(AbstractLifeCycle.java:39) at org.mortbay.xml.XmlConfiguration.main(XmlConfiguration.java:977) at java.lang.reflect.VMMethod.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:327) at org.mortbay.start.Main.invokeMain(Main.java:194) at org.mortbay.start.Main.start(Main.java:509) at org.mortbay.start.Main.main(Main.java:119) at java.lang.reflect.VMMethod.invoke(Native Method) at java.lang.reflect.Method.invoke(Method.java:327) at jamvm.java.lang.JarLauncher.main(JarLauncher.java:50) Caused by: java.security.NoSuchAlgorithmException: Algorithm [JKS] of type [KeyStore] from provider [gnu.javax.security.auth.callback.GnuCallbacks: name=GNU-CALLBACKS version=2.1] is not found at gnu.java.security.Engine.getInstance(Engine.java:191) at gnu.java.security.Engine.getInstance(Engine.java:105) at java.security.KeyStore.getInstance(KeyStore.java:188) It seems that keystore of type 'JKS' is not supported by classpath. is there any way to use keystore of type 'JKS' with classpath?

I will try to resove above issue but can somebody help me how to get or generate keystore file supported by the classpath ? is it possible to generate keystore supported by classpath bu some other tool like keytool from sun or can i get some sample keystore ? -- View this message in context: http://www.nabble.com/Problem-in-using-SSL-%28secure-socket%29-with-classpath-0.98-and-Jamvm-1.5.3-tp23997596p23997596.html Sent from the Gnu - Classpath - General mailing list archive at Nabble.com.
