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.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.
