Removing commit history in Git
To avoid committing files to version control you can add their names to a .gitignore file, and to committing local changes to an already version controlled file you can use the git command described in my previous post here.
How can you remove history if you’ve already committed a file? For example, let’s say you have a properties file with some environment specific values that you’ve committed, but you want to remove the history of those committed values?
This FAQ walks through the steps needed, which in summary are:
- Remove all history from the repo:
git filter-branch --force --index-filter 'git rm --cached --ignore-unmatch path/to/your_file_name' --prune-empty --tag-name-filter cat -- --all
- on Windows, replace the ‘ with “
- add the filename to .gitignore if you want to avoid future commits (and commit .gitignore: git commit -m “updated gitignore” )
- push changes back to your remotes: git push remotename master –force
If you need to make local changes to a tracked file and then not commit them in future commit, use the ‘git update-index -skip-worktree’ as described here.
Setting the default/welcome page for a JSF app
Since <welcome-file-list> only works with physical files, you cannot use a *.jsf filename here since this resolves to a different physical file (like *.xhtml).
To define a welcome file, use one of the following approaches:
- add an index.html file, and include a refresh meta tag in the head:
<head>
<meta http-equiv="Refresh" content="0; URL=your_welcome_page.jsf">
</head>
- add an index.jsp file, and redirect to your welcome page:
<% response.sendRedirect("dropdowns.jsf"); %>
Initializing a JSF ManagedBean
Sometimes things really are easy – the fact that I Googled how to do this now seems pretty silly. The more I use JSF the more I like it 🙂
To initialize the state of the ManagedBean that a JSF page is using (like to preload data, or initialize other displayed values), just call the code from the bean’s constructor. Simple as that.
For example
@ManagedBean
public class ExampleController
{
private String exampleProperty1;
private String exampleProperty2;
public ExampleController()
{
//example init code here, e.g. to init property values
}
...
}
