I' m trying to build dogtag rest client but after adding jars I found in system: here is the list: pki-ca.jar pki-certsrv.jar pki-cms.jar pki-cmscore.jar pki-cmsutil.jar pki-console.jar pki-kra.jar pki-nsutil.jar pki-ocsp.jar pki-tks.jar pki-tomcat.jar pki-tools.jar pki-tps.jar I got some problem with dependencies with them(resteasy was missing) so I resolved them with maven pom. Now i have problem with mozilla JSS lib. In mozilla ftp(https://ftp.mozilla.org/pub/security/jss/releases/) i found .jar and .so packages for difrent versions(from 3.0 to 4.3 ) but after checking all of them none of them have inner class SSLVersionRange in SSLSocket(check stacktrace bellow). So i checked what is dogtag source package dependecies and all i found in CMakeLists.txt is that dogtag is build with jss4.jar *So, my question is what exact version of JSS is dogtag using and where I can get it? * Exception in thread "main" java.lang.NoClassDefFoundError: org/mozilla/jss/ssl/SSLSocket$SSLVersionRange at com.netscape.certsrv.client.PKIConnection$JSSProtocolSocketFactory.connectSocket(PKIConnection.java:333) at org.apache.http.impl.conn.DefaultClientConnectionOperator.openConnection(DefaultClientConnectionOperator.java:177) at org.apache.http.impl.conn.ManagedClientConnectionImpl.open(ManagedClientConnectionImpl.java:304) at org.apache.http.impl.client.DefaultRequestDirector.tryConnect(DefaultRequestDirector.java:611) at org.apache.http.impl.client.DefaultRequestDirector.execute(DefaultRequestDirector.java:446) at org.apache.http.impl.client.AbstractHttpClient.doExecute(AbstractHttpClient.java:882) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:55) at org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:283) at org.jboss.resteasy.client.jaxrs.internal.ClientInvocation.invoke(ClientInvocation.java:436) at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientInvoker.invoke(ClientInvoker.java:102) at org.jboss.resteasy.client.jaxrs.internal.proxy.ClientProxy.invoke(ClientProxy.java:64) at com.sun.proxy.$Proxy37.listProfiles(Unknown Source) at com.netscape.certsrv.profile.ProfileClient.listProfiles(ProfileClient.java:59) at com.company.CATest.test(CATest.java:93) at com.company.Main.main(Main.java:15) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:497) at com.intellij.rt.execution.application.AppMain.main(AppMain.java:140)
