Maven free and public repository?

Hello,

We'd like to have a maven repository, to publish our projects. Are there
free available solutions in the market?

I have try to put my project on a apache webserver. It doesn't work
actually due to unknown reasons. I don't have the possibility to have my
own apache webserver due to technical or econimical reasons, neither
change the actual configuration of my website.

My sources are on codeplex.com, owned by microsoft. I don't want to put
them on java.net because java.net don't want to publish my projects.

In fact where should I go?
