[Pki-users] Startup problem

Hi! I tried to install the pki-ca as it mentioned in the documentation (yum install pki-ca). It finished successfully and /etc/init.d/pki-ca restart says OK but it doesn't run. I found only one relevant log file /var/log/pki-ca/catalina.out and it contains: java.lang.reflect.InvocationTargetException at java.lang.reflect.Method.invoke(libgcj.so.8rh) at org.apache.catalina.startup.Bootstrap.load(bootstrap.jar.so) at org.apache.catalina.startup.Bootstrap.main(bootstrap.jar.so) Caused by: java.lang.ClassFormatError: org.apache.tomcat.util.net.jss.JSSImplementation (unrecognized class file version) at java.lang.VMClassLoader.defineClass(libgcj.so.8rh) at java.lang.ClassLoader.defineClass(libgcj.so.8rh) at java.security.SecureClassLoader.defineClass(libgcj.so.8rh) at java.net.URLClassLoader.findClass(libgcj.so.8rh) at java.lang.ClassLoader.loadClass(libgcj.so.8rh) at java.lang.ClassLoader.loadClass(libgcj.so.8rh) at java.lang.Class.forName(libgcj.so.8rh) at java.lang.Class.forName(libgcj.so.8rh) at org.apache.tomcat.util.net.SSLImplementation.getInstance(tomcat-util-5.5.26.jar.so) at org.apache.coyote.http11.Http11BaseProtocol.checkSocketFactory(tomcat-http-5.5.26.jar.so) at org.apache.coyote.http11.Http11BaseProtocol.init(tomcat-http-5.5.26.jar.so) at org.apache.catalina.connector.Connector.initialize(catalina-5.5.26.jar.so) at org.apache.catalina.core.StandardService.initialize(catalina-5.5.26.jar.so) at org.apache.catalina.core.StandardServer.initialize(catalina-5.5.26.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.26.jar.so) at org.apache.catalina.startup.Catalina.load(catalina-5.5.26.jar.so) at java.lang.reflect.Method.invoke(libgcj.so.8rh) ...2 more What did I wrong? The Google wasn't my friend in this question. Every help or idea is welcome! :-) Thanks, Arpad Kunszt PS: The pki-ca server application really need rhgb, gtk and some other desktop packages in dependency?
