GlassFish tip: Broken or Corrupted domain.xml

August 31, 2007 § 2 Comments

domain.xml (located in GLASSFISH_INSTALL/domain/DOMAIN_NAME/config) is a key configuration file in GlassFish and it should never be edited by hand. So now that I’ve said this, I’d be lying if I said I never did this myself. And yes I’ve had times when my config file was corrupted which would prevent GlassFish from starting. If you end up with a corrupted domain.xml file *without* editing it by hand (never happened to me), you have one thing to do: file a bug with steps to reproduce.

If for some reason domain.xml is indeed corrupted (malformed XML or not compliant to the associated DTD), here are a few things you can do before or after the corruption:

• run the following command to verify the correctness of the file :
% asadmin verify-domain-xml

• restore the entire domain :
% asadmin restore-domain

…if you had previously backed it up :
% asadmin backup-domain

• if you’re happy losing all domain configuration (deployed applications, JDBC resources, JVM options, …) or desperately want to get back to a working domain, you can create a new one :
% asadmin create-domain domain-name

…or recreate default domain1 by first deleting it :
% asadmin delete-domain domain1

and running the setup script again from the root directory (GlassFish 2.x only) :
% ant -f setup.xml

You can also try to fix the content of this config file with a smart XML editor providing code completion, color syntaxing and well-formeness verification based on its DTD. If you’re using NetBeans, go to “DTDs and XML Schema Catalogs”. If you’re using GlassFish 3 and above, you probably want to read why there is no longer a DTD/Schema.
