I have a Java Web Services project that was created in an older version of NetBeans, and I haven't accessed it in many months, so my paths and installed libraries are different.

When I try to open the project, I get a "Resolve Reference Problems" dialog, and two Reference Problems are listed:

```
"metro" library could not be found
"JAX-WS-ENDORSED" library could not be found

```

I have a fresh installation of [JDK 6 Update 25 with NetBeans 7.0](http://www.oracle.com/technetwork/java/javase/downloads/install-jdk6-22nb691-177131.html), and am running Windows 7.

What steps can I take to solve this? I don't even know where to start, as every approach I've taken so far hasn't gotten me anywhere.

**Note:** JAX-WS-ENDORSED does not appear in my Libraries listing, so I can't remove it. Something hidden is referencing it. How would I find this?
