'we had difficulty reading this feed. host parameter is null' I am getting no where here, help!?

I've had an RSS feed created for an online video podcast but keep getting the message: 'we had difficulty reading this feed. host parameter is null' i've looked at the forums but none of them make any sense. My IT team say the RSS feed is valid and it should work and that is more like down to an itunes error, any help?

This will be our first podcast so do not currently have a page. Below is the feed.
Thank you Roger.

Getting null returned when working with Linked Lists

Ok, i'm having the same problem with a couple of methods that deal with linked lists, and i was hoping someone could lend me a hand. First off, the specifications for one of the methods:
An iterative procedure smallElements
PARAMETERS: a ListItem reference, ls
an integer n
RETURN VALUE: a new list identical to the given list, except
that it contains no occurrences of numbers greater than n.
for example, given input list ( 3 2 6 3 4 ) and 3,
the return value would be the list ( 3 2 3 )
And here is my code:
ListItem smallElements(ListItem ls, int n){
ListItem small = null;
ListItem result = small;
if(ls == null)
return null;
else{
while(ls!=null){
     if(ls.number <=n){
     result = new ListItem(ls.number, null );
     result = result.next;
     ls = ls.next;
return small;
Like the topic says, i keep getting null returned as a value. I have tried setting small= new ListItem(ls.number, null), and that actually returns the correct list, except that the first number is repeated twice. I would greatly appreciate any assistance.

I am not sure I understand your code. What exactly are those ListItems? It seems to me that you are dealing with single List elements, while the specification says that you are supposed to return a List.
But the main error is that you have two ListItem objects there, which seems to fill the same purpose - only that you use one, and return the other. 'small', which is the one you return, never get set to anything else than null.
I think you should do something like this: make a new, empty list to return
for element in parameterlist
    if number is smaller than n
        add this element to returnlist
return returnlist

We had difficulty reading this feed. host parameter is null

Hi,
I'm fairly new to creating podcasts and have come across the 'host parameter is null' error when submitting my podcast to itunes.
The RSS feed validates )bar the <itunes:link> tag to which I understand Feed Validator doesn't yet support due to previous errors. (correct me if i'm wrong)
I've tried linking copying the source code and uploading a XML file to the server and linking to that, but still get the same error in itunes.
Any help is welcome

Error Message from ITS "host parameter is null" - Huh?

I am having trouble submitting a podcast to the iTunes Store.
I have a podcast that I can access directly through my blog: blog.mindthegap.us
The RSS2 feed to my podcast is: http://blog.mindthegap.us/podcasts-only/rss2.aspx
I have subscribed to my podcast through the "Advanced" menu in iTunes. It finds my podcast and adds them to my podcast library.
BUT, when I submit my podcast to the iTunes Store, I get this message:
We had difficulty reading this feed. host parameter is null
I just spent an hour with tech support from godaddy determining that the feed is legit.
Can someone help me resolve why iTS won't take it?
Thanks

I had sumitted the same (or variations of the same) for nearly a week and after submitting the question to iTunes Technical Support, tried one more time.
Eureka! It was accepted. The only thing that I could possibly have changed was to have added some episode descriptions. The error message "host parameter is null" isn't very helpful if that WAS the solution.
Now, I can get back to my podcasts.

RSS Help - iTunes Error - "host parameter is null"

hello all,
I checked the history and there seems to be no answer why iTunes is giving this error, but that it some how fixes itself. I am trying to submit a new podcast (and podcast series) to iTunes. The error that I am getting is "host parameter is null". I am not creating the xml myself i am using Feeder and I have checked it again the FeedValidator.org. I am pretty sure that I have all the fields filled out. Any ideas?
Thanks
http://flixmakers.net/feeds/NoBudgetMovieMaking(MP4).xml
http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fflixmakers.net%2Ffeeds%2FNoB udgetMovieMaking%28MP4%29.xml

I'd start by taking those parentheses out of the URL - they might be the cause of trouble. If you want to let people know that this is an MP4 version of your feed, put the (MP4) in the podcast title.
Hope this helps.

Iweb/itunes problem - host parameter is null

i use iweb to publish and host our website. everything works fine, except... i have never been able to successfully publish a podcast to itunes through iweb. the error message in itunes is that the host parameter is null. i'm really scratching my head on this, because why would iweb offer an application that does not sync up with itunes automatically? please help!

The feed appears to be OK: it references a media file:
http://www.undergroundfellowship.info/undergroundfellowship/Media/uftv.intro.m4v
However making this URL into a link in an html page and then downloading from the the link produces not the m4v file but an html file called uftv.intro.m4v.html which references the media file:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

<frame src="http://web.me.com/growingdeeper/undergroundfellowship/Media/uftv.intro.m4v " frameborder="0" />
<frame frameborder="0" noresize />
</frameset>

I don't know how this is happening, or how this page is being generated, but it's what is causing the problem.

Host Parameter is null / Podcast submission

Hi there!
I'm starting a new podcast, in the hope that it will be avaliable via iTunes soon! but I hit a brick wall when I submitted my XML/rss feed to itunes and the following error message occured...
"We had difficulty reading this feed. host parameter is null"
What does it mean and how do i get rid of it?
here is my xml file >>> http://www.intfi.in/rss/intfi.xml
Any info wouldbe greatly appreciated!
+The Squire+ ^_^

pyrotech13 - your feed appears to be valid.
LBesquire: there are some minor errors in your feed. The 'lastpubdate' doesn't have a timezone (and is earlier than the date of the last episode) - also your dates are variously GMT or +0100. The 'itunes:subtitle' for both episodes is too long - they should be limited to 255 characters.
None of these errors is likely to be serious. Both feeds can be subscribed to manually from the 'Advanced' menu and work OK. I can't say why submitting them is failing, unless perhaps there is a temporary glitch in the system. Certainly the error message doesn't make much sense - it would suggest a failure to communicate with your servers. I should leave it for a day and try again. Do come back if you continue to have failures.

Host Parameter is Null Error

So i'm trying to publish my podcast on itunes, but all i get is ''Host Parameter is Null''. The rss feed has been created following itunes instructions, and it has been 100% validated on the feed validator. If you also paste our feed manually it works. this is the feed http://www.someguysonemic.com/rss.php

I had sumitted the same (or variations of the same) for nearly a week and after submitting the question to iTunes Technical Support, tried one more time.
Eureka! It was accepted. The only thing that I could possibly have changed was to have added some episode descriptions. The error message "host parameter is null" isn't very helpful if that WAS the solution.
Now, I can get back to my podcasts.

SOAP Axis receiver: host parameter is null

Hello,
we are on a PI 7.11 (SP06) system & we are trying to setup a scenario SOAP - SOAP (Axis) where we initiate a third party webservice. To connect to this service we are obliged to go through our proxy, which we defined in our JVM parameters:
http.nonProxyHosts: [*.ont.local|*.val.local|*.mon.local]
http.proxyHost: [proxypac.mon.local]
http.proxyPort: [8080]
http.proxySet: true
When we execute our scenario via soapUI we get following error:
com.sap.engine.interfaces.messaging.api.exception.MessagingException:
com.sap.engine.interfaces.messaging.api.exception.MessagingException:
XIAdapterFramework:GENERAL:com.sap.engine.interfaces.messaging.api.exception.MessagingException:
java.lang.IllegalArgumentException: host parameter is null
We already tried with http://proxypac.mon.local as parameter as well but still we get this error.
Furthermore we are able to make a connection to the service via a SM59 connection.
Axis details:
Adapter Common Library Version: 1.7.1106.20110202095400.0000, NW711_06_REL
Adapter Application Version: 1.7.1106.20110202095400.0000, NW711_06_REL
Axis Version: Apache Axis version: 1.4 Built on Apr 22, 2006 (06:55:48 PDT)
Many thanks in advance for your help,
Frédéric.

For the Axis receiver it looks like one of the handlers can't get the value of our host parameter.
Any help or tips would be really appreciated!

how to solve this problem....
please help me
Best Regards
Ravi Shankar B

Hi Ravi,
First i would suggest you to test/execute the webservice to makesure that its working properly.
If yes, pass all the madatory fields to the webservice input parameters. In your case customerID could be a madatory parameter to get the address.
You can pass that parameter by customer.setCustomerNo().

Getting "null" when trying to commit

Dear All,
am using Jdeveloper 11.1.1.3 ...
i have a master-detail jsp page , i tried to insert a new row and when i commit the transaction ( press on the commit button ) nothing happen i mean the transaction is not saved and when i checked the log of the IntegratedWebLogicServer i found the the commit generated no error just "null" was there in the log , i have other pages working correctly am not sure what is wrong with this one ...this is a very serious problem since no error message was generated to the user !!!
Any help please

problem solved !! the problem was that i wrote this statement
if ( ADFContext.getCurrent().getSessionScope().get("ClientType").equals("1") ) ....
and this session scope parameter returned null thats why ... i changed into the following then it worked if ( ADFContext.getCurrent().getSessionScope().get("ClientType") ==1 instead of .equals
but am not sure why this didnt generate an error message , that way we could know what is the problem

Error: Operation illegal on linked parameter.

Hi,
I am running a reports from c# application after updating datasource to a dataset. But I get the following error when running reports with sub-reports.
Error in File RptGroup {37DC74F5-5A6A-4517-AA4C-D5D9C5991968}.rpt:
Operation illegal on linked parameter.
I am updating all stored procedure parameters for the report, but not doing anything for other parameter types. What should I do to get rid of this error?
Thanks
Ajith

Well,.I thought I was not setting values for parameter types other than stored procedure, but I was.
rptParam.ApplyCurrentValues(rptParamValues); was outside the code that loops through parameter values.
I have fixed this and the code is working fine.
Thanks.

List of Homes on this system:
Inventory load failed... OPatch cannot load inventory for the given Oracle Home.
Possible causes are:
   Oracle Home dir. path does not exist in Central Inventory
   Oracle Home is a symbolic link
   Oracle Home inventory is corrupted
LsInventorySession failed: OracleHomeInventory gets null oracleHomeInfo
OPatch failed with error code 73
-bash-3.2$Any idea what could be wrong

From which OS user you are applying the patch? Is it the same user who installed the Oracle in first place? It looks like a permission problem.
