I have a Tomcat5.5.9 server that works fine with JDBCRealm. I am trying to configure a customRealm for the sever. The customRealm.jar file was placed in the directory of $Tomcat_Home/server/lib. The realm in the server.xml has been defined as:
<Realm className="edu.aces.realm.JDBCUnixRealm" connectionName="XXXX" connectionPassword="XXXXXXX" connectionURL="jdbc:mysql://oscar.acesag.auburn.edu:3306/authenticate" driverName="org.gjt.mm.mysql.Driver" roleNameCol="role_name" userCredCol="user_pass" userNameCol="user_name" userRoleTable="tomcat_user_roles" userTable="tomcat_users" validate="true" /> After starting tomcat, I can see tomcat page via IE browser, but when click on Tomcat Manager, just got a blank page. I got exception in catalina.out as: WARNING: Exception executing accept java.net.SocketException: Invalid argument at java.net.PlainSocketImpl.socketSetOption(Native Method) at java.net.PlainSocketImpl.setOption(PlainSocketImpl.java:264) at java.net.Socket.setSoLinger(Socket.java:869) at org.apache.jk.common.ChannelSocket.accept(ChannelSocket.java:300) at org.apache.jk.common.ChannelSocket.acceptConnections(ChannelSocket.j$ at org.apache.jk.common.SocketAcceptor.runIt(ChannelSocket.java:852) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(Thread$ at java.lang.Thread.run(Thread.java:595) In most case this exception means "The server is not running (nobody is listening on the specified port)" or "The host is not reachable". Is there any additional configuration I missed? How to fix this problem? Please help.
