User development, A new message was posted in the thread "Editing the JBoss AS Configuration": http://community.jboss.org/message/530070#530070 Author : Csaba Toth Profile : http://community.jboss.org/people/tothc Message: -------------------------------------------------------------- Thanks for the quick reply Denis,   The twiddle.jar is there in JBOSS_HOME\bin, and if I look into it, the MANIFEST.MF contains "5.1.0.GA" as Specification-Version. Then what does it do with this info? BTW, I selected But the dialog still displays the error message about the run.jar. I don't have JBOSS_HOME\server\conf directory, but instead I have JBOSS_HOME\server\default\conf.   BTW, this dialog is a page in a Wizard. The previous page of this wizard is the "Define a New Server" dialog, Where I selected "JBoss AS 5.1" as the server type.   What should I do? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530070#530070
