Setting web part title from resource file

Question

I am trying to set web part the title and description through a resource file. My .webpart file has this content:

<?xml version="1.0"?>
<webParts>
  <webPart xmlns="http://schemas.microsoft.com/WebPart/v3"&gt;
    <metaData>
      <type name="MyWebParts.MyWebPart" />
      <importErrorMessage>Cannot import this web part.</importErrorMessage>
    </metaData>
    <data>
      <properties>
        <property name="Title" type="string">$Resources:MyWebPartResources,WebPartTitle</property>
        <property name="Description" type="string">$Resources:MyWebPartResources,WebPartDescr</property>
      </properties>
    </data>
  </webPart>
</webParts>

I have put the resource file in 12\Resources folder.

But, the Add Web Part dialogue does not seem to be picking the title and description from the resource file.

Have anyone fixed this?

Update-1: On Add Web Part dialogue, I see the following instead of the text in resource file:

$Resources:MyWebPartResources,WebPartTitle
$Resources:MyWebPartResources,WebPartDescr

Answer 1

The resource file needs to be in websiteroot/App_GlobalResources I think.

The contents of 12/Resources folder only gets copied to App_GlobalResources when the web application is first created.

Answer 2

The link, SharePoint Internals: Resources (given by, anchorpoint in the comment) helped a lot. Lee Dale is also correct. Though, Still it didn't work on my machine for the first time even though I was correct. It may be because of some caching issue.

Later, I tried clearing temporary internet files, deactivating and activating the feature, it worked!
