Roller Tips: Titles as Permalinks and Category Display A few more tips for your Roller blog. You can edit your "_day" template to make your titles permalinks. I just added this feature to this site - try it now by clicking on this title for any post. To enable this feature, simply wrap your $entry.title element with a permalink URL. For example, change <b>$entry.title</b> to the following: 

<a href="$baseURL/page/$userName?anchor=$entry.anchor" 
   style="font-style: bold; color: black">$entry.title</a>

Adjust the style as appropriate for your theme. The second tip is to add the ability for users to see the category you've posted to. Simply add the following under the $entry.title entry to display the category name in the top right corner of the post: 

<span class="dateStamp" style="float: right">
    Category: $entry.category.name</span>

Again, the CSS for the span may depend on your theme. Lastly, if you click on a permalink for your blog and you're not routed to the specific entry you expect, for the love of God add the following before your $entry.title.

<a name="$entry.anchor" id="$entry.anchor"></a>

Infact, thanks to a tip from Sergio I used the $entry.category.name to display an icon for the relevent category.

This may be kind of silly - but do you know how to retrieve the anchor part of the url in a jsp or servlet? I tried HttpServletRequest.getRequestURL(), but the "anchor" part is missing.

Will, I believe that request.getQueryString() is what you're looking for.

<p/>No, that really doesn't work. I want the anchor part - the part after the "#" sign. <p/>I made a simple jsp with one line: <%= request.getQueryString() %>
With a request url of "http://localhost:8080/testgeturl.jsp?bob=5&tom=4#someanchor"
The output is: bob=5&tom=4 <p/>Any other ideas? I assumed that perhaps the anchor wasn't sent with the html request...but obviously that isn't the case!

Hmm, well, velocity runs under java, so it has to be in there somewhere, huh?

To be honest, I don't have an answer for you. I just know that the anchor (everything after #) is recognized by browsers, but I don't know that there's any way to retrieve it using Java. You'd think it's possible, but I've never had a need to grab it.

[Trackback] OK, so I've been hacking my template to pieces again, you will see some changes soon, but importantly for now, thanks to Matt Raible I have made the titles of each story their own permalink, as well as the little '#' down in the comments bar, which s...
