FOMUnsupportedTextTypeException - Remove type="Text/Html" attribute from Atom feed

Question

I am having trouble getting entries from parsed Atom Feed. I am getting these feed from web service. Thing is Code work absolutely fine in my local server but when I deploy it on my dev box I am getting FOMUnsupportedTextTypeException Exception. when I check the difference in generated Atom feed i found little change in feed xml. below is my local feed

<atom:entry>
<atom:id>e0f7f5e7-a5f3-4a2e-a87d-d8def2b6bc2c</atom:id>
<atom:title">Locations</atom:title>
<atom:author>
<atom:uri>uid=wpsadmin,o=defaultWIMFileBasedRealm</atom:uri>
<atom:name>wpsadmin</atom:name>
</atom:author>

and here my dev box generated xml.

<atom:entry>
<atom:id>e0f7f5e7-a5f3-4a2e-a87d-d8def2b6bc2c</atom:id>
<atom:title type="text/html">Locations</atom:title>
<atom:author>
<atom:uri>uid=wpsadmin,o=defaultWIMFileBasedRealm</atom:uri>
<atom:name>wpsadmin</atom:name>
</atom:author>

the only difference is type="text/html"in atom:title

I am using abdera parser to parse atom and using IBM Portal 8 in both local and dev.

I am getting error at this code

Document<Feed> doc = response.getDocument();   
Feed feed = (Feed) doc.getRoot();   
for (Entry entry : feed.getEntries()) {  //exception at this line

exception is FOMUnsupportedTextTypeException

Can anybody tell me how to remove type="text/html" attribute from atom:title?

Answer 1

As the Atom spec shows, that feed is incorrect:

Text constructs MAY have a "type" attribute.  When present, the value
MUST be one of "text", "html", or "xhtml".  If the "type" attribute
is not provided, Atom Processors MUST behave as though it were
present with a value of "text".

Abdera is correct to reject it. From your question, it seems like that feed is being generated by Lotus Web Content Manager; if so, that's a bug in WCF that may have been fixed. If those two boxes are producing different feeds, perhaps they're running different versions.

Edit: From your other question I can see that your code is fetching the feed from azeez:10039/wps/mycontenthandler/. You need to figure out why your two environments are producing different feeds here rather than trying to patch up invalid data.
