The last of your messages is strange:
vfsfile:/C:/jboss5/server/default/deploy/management/console-mgr.sar/ -> java.lang.NoSuchMethodError: org.jboss.system.server.ServerConfigLocator.locate()Lorg/jboss/system/server/ServerConfig;
Seems a JBoss integrated app does not work. Do your own apps (ReportsWeb.war, crystaljsp.war) contain JBoss system classes from 4.2? Is your JBoss installation a plain new version, or did you add e.g. JARs to /common/lib or other directories?
Also, did your see this part of what you posted: "(SEE PREVIOUS ERRORS FOR DETAILS)"? There should be stack traces earlier in the console log that detail what the causes for the error are - what you posted was just a report that said things failed. (You might need to increase the console buffer size to prevent the exception stack traces from overflowing the buffer - I set mine at 9000 lines).
