oms_error Message:[oms] empty or null xml map request string.

I'm using mapviewer. I create a stored procedure in oracle that uses the utl_http package to make the map request. The omserver response with an error but when i make a map request via internet explorer the server response its ok and show me the correspondent map. This is my pl/sql code it fails in this line:
UTL_HTTP.SET_HEADER(l_http_req, 'Content-Type', 'application/x-www-form-urlencoded');
     UTL_HTTP.SET_HEADER(l_http_req, 'Content-Lenght', LENGTH(map_request));
     UTL_HTTP.SET_HEADER(l_http_req, 'Host', 'cobogis09');
     UTL_HTTP.SET_HEADER(l_http_req, 'Port', '8888');
As you can see it tells to me that the map request string is empty but im sending the map request in the next way:
     UTL_HTTP.WRITE_TEXT(l_http_req, '<?xml version="1.0" encoding="UTF-8"?><map_request datasource="stream" srid="8307" basemap="" width="960" height="768" antialiasing="false" format="GIF_URL" title="Demonstration"></map_request>');
     l_http_resp := utl_http.get_response(l_http_req);
     utl_http.read_text(l_http_resp, l_value);
     response := sys.XMLTYPE.createxml(l_value);
     utl_http.end_response(l_http_resp);
     img_url := response.EXTRACT('/map_response/map_image/map_content/@url').getstringval();
img_url := response.EXTRACT('/map_response/map_image/map_content/@url').getstringval();
obviously because the server response its not ok
the server response is (i get this message in my l_value variable):
<?xml version="1.0" encoding="UTF-8"?><oms_error>Message:[oms] empty or null xml map request string.

What i want to know its why the server says that the map request string is empty. As you can see the map request is not empty, but when i send to the server something happens that sends this map request string empty to the server.
The next is the console of the omserver:

As you can see the arrive empty to the server, what can be wrong

Hi,
in this map request, it looks that the basemap string is empty.
UTL_HTTP.WRITE_TEXT(l_http_req, '<?xml version="1.0" encoding="UTF-8"?><map_request datasource="stream" srid="8307" basemap="" width="960" height="768" antialiasing="false" format="GIF_URL" title="Demonstration"></map_request>');

Display Error message in Empty grid

Hi All,
A query again !!!
I have an AdvancedDataGrid , in which I want to show an error msg , No Records found , if my dataprovider is null.
I dont want to show an alert.
Want to display a message in empty grid.
How can I do that,if someone can help?
Thanks in Advance
Ashudeep

It depends on why the dataProvider is null.
If your remote object has not returned data, you can detect that in its result handler, and then manually construct a data item that has a message in one of the fields, but null in the rest.
If this post answers your question or helps, please mark it as such.

Question about XML mapping to ABAP internal table

Hi experts.
I'm trying to XML mapping. But it doesn't work well. Assume there are XML file as below.
<HEADER>
<ITEM>
    <FOO>123</FOO>
    <BAR>ABC</BAR>
</ITEM>
<ITEM>
    <FOO>456</FOO>
    <BAR>DEF</BAR>
</ITEM>
<HEADER>
and I want to trasformation it as below.
ITAB
FOO       |      BAR
123         | ABC
456         | DEF
How could I trasformation using "call transformation"?

ExcelXML mapping---problem with XML maps in Excel sheet

Hi Friends,
I have one issue with ExcelXML mapping in Xcelsius.
The problem is I have designed one dashboard using ExcelXML mapping and everything is working fine but I was afraid that I could not able to find the mappings which were embedded in Excel.It happened many times.What I was doing is everytime Im re-mapping.I could be a big problem for me to do this procedire for everytime.How to recover my XML maps into excel sheet.Can anyone please provide the solution to achieve this.

Shouldnt it be equivalent ? I mean, as far as I know the ns0: shouldnt be a problem
when you have a namespace in the message then you need to associate it with some prefix....since ns0 (or any other prefix) is not present you are getting the error....having the namespace but not ns0 is the problem.
XMLAnonymizer bean may help you to add the namespace prefix...

InterConnect - FTP adapter:Message queue empty

Hi,
I have installed oracle InterConnect 9.0.4.
The send point and receive end point are configured as separate folders
ota.send.endpoint=ftp://hcsdlx01/interexample/sender/
ota.receive.endpoint=ftp://hcsdlx01/interexample/receiver
We have placed an xml file at the sender location.
And trying to retrieve at reciever end point
But we are getting a message saying message queue empty in the oailog.txt
can anyone shed the possible sources of error.
Regards
Venkat

Finally succeeded in spotting error.
The FTP adapter.ini file was not configured properly
The point is that The send point and receive points should be as per the file system.
In our case the endpoint as we see in browser say:
ftp://example/endpoint
but in the file in Unix server was
<dir1>/<dir2>/endpoint
In the adapter.ini we changed to endpoint = <dir1>/<dir2>/endpoint.
It started working properly,
Thank u marcus

How to check if message is empty in Integration Process

Hi!
I have Integration Process with container object OUT_CR This type of message I get from another message using xsl-mapping. The point is that result message can be empty (only message header - "<MT_1C_BXY_CR/>").
In Integration Process I place the step Switch where I use condition to determine if my message is empty and if it's not - to send it to receiver system.
I'm beginner in PI and it's the first time I try to use Condition Editor. I tried to put condition like "EX OUT_CR./p1:MT_1C_BXY_CR/ONE" but it doesn't work.
Could you advise me how can I check If the message is empty using Condition Editor in IP? Or may be any tutorial on working with Condition Editor in PI?

you might have to try the XSL function exists - http://www.w3schools.com/xpath/xpath_functions.asp
Try the EX operator as shown in this blog Customise your 'XPATH' Expressions in Receiver Determination

XML MAPPING - swf not updating

When I make a change to the xml file it is not picking up the change in my published swf file. When I open the project in CX and refresh the mapping updates.
So it is connected but when I click on "refresh" on the sxf it is not updating.
I have xml maps, added in the data connection manager, with a refresh button tied to the xml connection. I also have the refresh on load checked in the connection manager.
Need help.
Thanks
Mark

Shamim my scenario was that I wanted the SWF on a network so that a call center employee could access the file from a mapped drive, open the file direct on her/his client machine. My problem was that I developed the file on the server machine and mapped the data connection path to the XML initially from the server, not the scenario of a client machine's path looking for the file. (not sure if cache is the right term)
Initial Path from server development.. D:\Datafiles\data.xml
The client machine(s) network path, mapped drive was Z: for example. In the excelsius model you need to bind the data path to the excel model and hardcode the Path that the client machines will go thru to access the data. This solved my issue perfectly. Z or name of the mapped drive mapped to the server.
Z:\Datafiles\data.xml
So now if your on the server machine and try to open the file from the swf you will incur the error message that correlates to the swf not being able to find the data. From the clients works fine but not from the server machine as the path has to be exact for the swf to find the data file.
Hope this helps.
I have a question for trying to deploy this same example on th server embedded into a swf movie player to the web. Might have been my path issue, cross domain policy file... But I could not get it to be deployed in a website, live. If you are familiar with this please explain to me.

Mark

Xpath Debatching in Orchestration -The part 'part' of message 'Message_In_Copy' contained a null value at the end of the construct block

Hi ,
Facing strange issue in Xpath debatching in Orchestration.
Getting following error in construct shape:
The part 'part' of message 'Message_In_Copy' contained a null value at the end of the construct block
Code inside the construct block:
sXpath = System.String.Format("/*[local-name()='Customers' and namespace-uri()='http://Debatch.Customer']/*[local-name()='Customer' and namespace-uri()='http://Debatch.Customer' and position()={0}]", nLoopCount);
System.Diagnostics.Debug.WriteLine(sXpath);
Message_In_Copy= xpath(Message_In, sXpath);
Schema used:
<?xml version="1.0" encoding="utf-16"?>
<xs:schema xmlns="http://Debatch.Customer" xmlns:b="http://schemas.microsoft.com/BizTalk/2003" targetNamespace="http://Debatch.Customer" xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="Customers">

</xs:sequence>
</xs:complexType>

Can anyone help me out ? to identify the root cause for above issue.
Thanks,

I agree with Shankycheil here, querying XPath will return XMLNode and thus can't be assigned to XMLNode.
But for debatching in Orchestration using Xpath is not a very good idea.
Because using XPATH loads the complete message in memory(XML Structure) and then performs processing.
This approach is always prone to throwing Out of Memory exception and low in performance also.
Therefore I would suggest you to perform debatching by calling XML Disassembler(XMLReceive) pipeline.
As pipeline works with Stream it will have better performance and you will also get complete control over the messages.
Refer the below samples for debatching using XML Receive pipeline within Orchestration.
Comparrison between XPATH and ReceivePipeline for Debatching:-

How to handle source empty field in FDM maps

Dear all,
In our projects, data was extracted from EBS with ERPi adapters to HFM through FDM. In this case, some source fields are empty after the data extraction from EBS. The problem is, how can I deal with the empty field in the maps. For now, the workaround is using wildcard (like *->[None]), sth like that. But there is a risk in it, it may happen to ignore some records with error. Do your guys know any special characters stand for the Null in the mapping?
Thanks!

We have had a workaround solution since moving to V11. This was not a problem in System 9.
The issue with blanks not defaulting to [None] is that some values escape the test. Such as forcing default values using "Like (* = [None])". If a new code is in your data that is not in your map, the Validation process foiled since [None] is valid and all blanks are now [None]. Only then do you either have an intersection violation that shows up during Export or you get bad data in HFM.
I don't like this new "feature" in S11 FDM. We will be submitting a request to have the default functionality added back. Perhaps as an option?

XML mapped directly into dbtable

Hi guys,
I've one doubt related to xml mapping. I've searched and read lots of posts on the forum about XML, but the doubt is still remaining...
Imagine I have a XML response to an webservice and I'd like to pass it to an dbtable.
I know I can use DOM to parse the xml, and I've even seen I can build a table based on hierarchies nodes, but what I'd like to know is if it's possible to pass all the content from the XML directly to my dbtable.
Why do I want to do this? Because the xml which is sent is really huge, and if I'd have to parse it, there would be tons of abap code.... So, I'd like to pass it directly to my table...
I could validate the xml with a DTD and then if there were no errors, I would pass it directly to the dbtable...
Is there any way of doing it?
I'm really thankful for your answers....

Hi,
If you are looking at passing the whole XML response into a field in the target, this would be simple.
Convert the InputStream ( In Java Mapping) into a string and pass it to the String.
You can use this code to convert InputStream to string,
In this code, <b>in</b> is the inputstream to the execute() of java mapping,
BufferedReader inp = new BufferedReader(new InputStreamReader(in));
StringBuffer buffer = new StringBuffer();
String line="";
while ((line = inp.readLine()) != null) {
buffer.append(line);
String source=buffer.toString();
is this what you are looning at?

Copy of source message to an element with graphical mapping

Hi all,
Is there a way to copy the complete source message of a mapping to an element of the destination message (with CDATA) with the graphical mapping (or UDF, but I want to avoid XSL) ?
For example, from this message:
<source>
<element>test</element>
<element2>test2</element2>
</source>
I expect the following result:
<dest>
<data><![CDATA[<source><element>test</element><element2>test2</element2></source>]]>
</data>
</dest>
Thanks for your help.
Greg

Source selection is empty due to inverse mapping

Hi Experts,
When execute data collection task, one of Cons unit got the below error.
"Source selection is empty due to inverse mapping" Message no. UCT8250.
I checked BI mapping rules and also compare mapping rules in LDS with other cons unit. There is no change in mapping rules in LDS and nothing had changed in BI mapping rules.
This is error is shown for one cons unit only, for all remaining task run successfully. Please explain me how to overcome from this.
NB: Data collection method was Load from data streams.

Hi Madhu,
Please could you elaborate on the master data field in BI (RSA1) as I could see SAP note 751686 to bypass the error message, as the error could be due to incomplete data for the respective company.
Awaiting your early response
Regards,
