The simple procedure on this page describes how to change the default view of issues from 'Comments' to 'All'. To do this, change the configuration file which controls the display of the tabs:

  1. Edit the file <jira-install\WEB-INF\classes\system-issuetabpanels-plugin.xml).
  2. Each tab is controled by a <issue-tabpanel> tag. To change the default selection, the <default>true</default> needs to be placed in the wanted <issue-tabpanel> tag.
