Hi All, I want to display Blog of specific category on the main page. I want
to keep the existing content (an image and mostly text) and also include a
section for blog roll tagged as 'News'. Is there a way to display/include
the latest blog entry tagged to a certain category? Thanks in advance for
your time.

Well, I tried something using Xwiki Query Manager. Code below -
{{velocity}}
#set($resultDocuments = $services.query.xwql("from
doc.object(Blog.BlogPostClass) as blog where blog.published = '1' and
:category member of blog.category and blog.hidden = '0' and doc.web =
'Blog'").execute())
#foreach($resultDocument in $resultDocuments)
$resultDocument
#end
{{/velocity}}
I get this below error. What is programming right and how do I enable this
right?
Caused by: org.xwiki.query.QueryException: Full form statements requires
programming right. Query statement = [select doc.fullName where from
doc.object(Blog.BlogPostClass) as blog where blog.published = '1' and
:category member of blog.category and blog.hidden = '0' and doc.web =
'Blog'] at
org.xwiki.query.internal.SecureQueryExecutorManager.execute(SecureQueryExecutorManager.java:88)

I'm not known in the velocity scripts but I implement the Blog entries as a RSS feed.
Maybe that helps you in a other way.

I don't get this error. I get another one, because you didn't bind the
parameter value. So adding
.bindValue('category', 'Blog.News')
before executing the query fixes the problem for me. See
http://extensions.xwiki.org/xwiki/bin/view/Extension/Query+Module#HXWiki-sp…
for what a short form query is. As for what Programming Right is, it
controls whether users can use protected APIs & Groovy code in wiki
pages.
Hope this helps,
Marius

Thank you all for your input. Here is a snippet of code that solves my
problem.
{{include document="Blog.BlogCode"/}}
{{velocity filter="none"}}
{{html clean="false" wiki="true"}}
#set($blogDoc = $xwiki.getDocument("Blog.Webhome"))
#getBlogEntries($blogDoc $entries)
#foreach ($entryDoc in $xwiki.wrapDocs($entries))
#getEntryObject($entryDoc $entryObj)
#if($entryObj.getxWikiClass().getName() == $blogPostClassname)
#set($categories = $entryObj.getProperty('category').value)
#set($first = true)
#if($categories.size() > 0)
#foreach($category in $categories)
## Do not indent
#set($categoryDoc = $!xwiki.getDocument($category))
#set($result =
"$!categoryDoc.getObject(${blogCategoryClassname}).getProperty('name').value.trim()")
#if($result == 'Category1234')
#displayEntry($entryDoc $entryObj true true)
#end
#end
#end
#end
#end
