Changed server name, reconfiged emca, still getting java errors on console

Question

I installed 10gr2 with local database control only, and had all working fine. I then moved the server into production after testing and changed the server name. Of course this changed all the settings for dbconsole so I ran the emca config again from some info I got off of this forum a week or so ago. I can't seem to find that thread any more, and I need to get this working. I could not find any more references to the old server name, but the java error is still showing one. I can bring up the login page and login, but then it wont display any info.
I've been searching to see what I need to do to totally re-install the local database control component but can't seem to find anything. I am also going to eventually have grid control running on another machine as well, but I imagine that I still have to have all the proper things in place on this server before I can connect either thru grid control or locally in any case.

REPOSITORY_URL=http://winms-wwscale.millsite.net:5500/em/upload/
I searched every file in the <server url> directory and changed any references to the old servername to the new one. The only ones that showed up were for isqlplus items.
I am pretty sure I have run the "emca dbcontrol db -repos recreate" command, but perhaps I'll do it again. I also have a thread going on this in metalink and one suggestion is to do the following:
SHUTDOWN IMMEDIATE;
STARTUP RESTRICT;
A. Drop the repository manually using following procedure.
Stop the DB Console if not already stoped: $ORACLE_HOME/bin/emctl stop dbconsole
Log on in sqlplus as sys user and run the following commands:
a. drop user sysman cascade;
b. drop role MGMT_USER;
c. drop user MGMT_VIEW cascade;
d. drop public synonym MGMT_TARGET_BLACKOUTS;
e. drop public synonym SETEMVIEWUSERCONTEXT;
(Note If any of the above statement failed and saying object doesn't exist just skip that
statement)
B. Drop the DB Control configuration files.
Remove the following directories:
$rm -rf $ORACLE_HOME/<HOSTNAME_SID>
$rm -rf $ORACLE_HOME/oc4j/j2ee/OC4J_DBConsole_<HOSTNAME_SID>
On Windows systems just delete the folders above from the Explorer.
You have to replace the values in the <> with the correct values from your environment .
The shutdown and startup restrict seems a tad severe to me, I'm thinking thats if others may be trying to access the database control page while you are doing all of this.
