UCCX8 - script that reads XML file failing, used to work fine in UCCX 5 and 7

I have a existing script that I've used many times before to read a simple XML file to check open hours for a queue. In both UCCX 5 and 7
I loaded up all my same scripts, documents , structure, etc..
When I run script I get the below error.
The error implies its a security problem but I also wonder if it could simply be a incorrect directory structure as well
I have the document located in the repository under en\GlobalDocuments\HolidayDatesWithHours.xml
Is there a differnet way we need to reference documents in UCCX 8 than 5 or 7
I think I doing it correctly, using the CreateFileDocument and CreateXMLDocument steps, NOT trying to access the filesystem directly
Do I need to use forward slashes in the file path for UCCX 8 ,
Any ideas where to look. This same error appears wherever in my script that I'm trying to read a XML file. different scripts as well so it seems that I'm doing something consistently wrong that used to work correctly on multiple UCCX 5&7 servers in the past.
Thanks.

It should be fine, I assume you mean to reference the full location of your files such as:
DOC[en\GlobalDocuments\HolidayDatesWithHours.xml]
Or you could use a document variable such as:
docVariable = DOC[en\GlobalDocuments\HolidayDateWithHours.xml]
then in the script reference that:
doc = Create XML Document (docVariable)

Reading XML file to use its content

Hi, I'm trying to read from a XML file that contents the following:
<conf>
<address>some address</address>
<body>some body message</body>
</conf>
I'm using the following code to try to read it:
import java.io.*;
import javax.xml.parsers.*;
public class XMLReader {
public static void main(String[] args) throws Exception {
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder parser = factory.newDocumentBuilder();
Document documento = parser.parse(new File("C:/salida.xml"));
Element elemento = documento.getDocumentElement();
System.out.println(elemento.toString());
catch (Exception elemento) {
elemento.printStackTrace();
I though it was good, but it gives me compilation error, it says it 'cannot resolve symbol' on "DocumentBuilder parser = factory.newDocumentBuilder();", I already added the following libraries: jaxp-api.jar, sax.jar, dom.jar, xalan.jar, xercesImpl.jar, xsltc.jar (all from JAXP API). So, I don't know what else do I need to make it work, what is it?, thanks in advance.

try this:

InputSource iSource = new InputSource(fis);
parser.parse(iSource);

Read XML file in WEB-INF works in exploded format but fails in EAR

I'm able to read an XML file stored in the WEB-INF when my application is deployed in the exploded format, but when its deployed in an EAR, the reading fails.
          I read from forums that getRealPath could fail, so I added in the getResourceAsStream to fall back on. But in the EAR format, both fails.
          What did I miss out?
          Here's my codes:
                      StringBuffer configFileName = new StringBuffer();
            configFileName.append(File.separatorChar).append("WEB-INF");
            configFileName.append(File.separatorChar).append("app-config.xml");
            String fileName = getServletContext().getRealPath(configFileName.toString());
            if (fileName == null) {
              request.setAttribute("efs/xmlmappings-is", getServletContext().getResourceAsStream(configFileName.toString()));
            } else {

Droplet Script used to work fine in Tiger and Leopard, now doesn't

Hey everyone,
I'd like to apologize in advance, I'm not really good with AppleScript and was only able to create my droplet in the first place by changing little bits of a Droplet example script I found on the internet (I forgot where I found it, but it might even have been here at Apple).
The script worked perfectly fine in Tiger and Leopard but throws an error in Snow Leopard. The error says "Can't make alias "...filepath... "into type file."
The problem is that I can't find the problem in my script. I don't get any indication which line it may be and I hope someone here will be able to help me.
I also tried Script Debugger, but the script works there! So that doesn't help either...
I'd appreciate any help, here is the script:
-- QuickTime supported image formats

end if
end repeat
end open

if (exists file new_name of the parent_folder) then
error "A file named \"" & new_name & "\" already exists."
end if
-- open the image file
set this_image to open this_file
-- save in new file. The result is a file ref to the new file
set the new_image to save this_image as PNG in file new_name of the parent_folder with icon

set the default_name to this_name
else
set the default_name to text 1 thru -((length of this_extension) + 2) of this_name
end if
return (the default_name & "." & the new_extension)
end add_extension

Here's the faulty line:
--open the image file
*set this_image to open this_file*
The command open doesn't return anything that could be assigned to the variable this_image.
I also wonder if it wouldn't be better to add “as alias” at the end of each of the following two lines:
*set this_info to the info for this_file*
*set the item_info to info for this_item*
I hope this help.

How to read XML file kept on NON-SAP server using the Http URL ?

Dear Experts,
I am working on CRM2007 web UI. I need to read a XML file placed on a shared server location by a third party program. Then process that XML file into CRM and create a quotation using the data extracted from the file.
All i have with me is the http URL that points to the location of the file.
I am supposed to read the file , create quotation and at later point of time i would be asked to update the quotation and then generated new XML representing updated quotation and replace the XML file on shared server location with this new updated XML file.
I know how to extract data from XML file into ABAP but i have no clue as to how to access the file on some other server using the http url i have and how to read it ?
I searched on the forum and i found the codes for reading XML file that is located either on client machine OR on the Application server wheareas my file is on some other than sap application server.
Please help me as its an urgent issue .
Points will be rewarded for sure.
Please help.
Thanks in advance,
Suchita.
p.s. : the http url to the file location is like -->
http://SomeServerDomain/SomeDirectory/file.xml

hi,
interesting task.
to request the file by a http call you need to create an if_http_client object.
More info is [here|http://help.sap.com/saphelp_nwmobile71/helpdata/en/e5/4d350bc11411d4ad310000e83539c3/frameset.htm]
to parse the file you either have to work with the ixml packages ([info|http://help.sap.com/saphelp_nwmobile71/helpdata/en/47/b5413acdb62f70e10000000a114084/content.htm]) or you use an XSLT transformation ([info|http://help.sap.com/saphelp_nwmobile71/helpdata/en/a8/824c3c66177414e10000000a114084/content.htm]).
uploading the final file isn't so easy. if you only have http, you should write a server script to allow uploading of the new file and copying it into the place of the old file. but you definitely need the script.
now it's your take. depending on how experienced you are in ABAP and networking this might turn out to be easy or pretty complicated.
have fun,
anton

Reading XML file using BAPI I must use adapters .

Reading XML file using BAPI and then uploading that xml file data into SAP using BDC.
I cant take file on to my Application server I am getting the file dynamically from other file server and I need to use BAPis to read data from XML file.please tell me what should be my Import,Export and Tables parameterrs should be.
Thanks

Hi,
Import, export and table parameters for BAPI is required, without that BAPI will not able to collect the data from XML. What you need to do is write a Zprogram and collect the data, store that data in internal table and call the BAPI by passing required parameters.
Different Scanarios:
1) Before calling a BAPI write some other program which collects the data from XML and create a UNIX file. Try to get the data from UNIX FILE
2) If you see the XML tags, data will be in side that tags, try to get the data from XML tags and store that data in one SAP table. You can use the BAPI by fetching the data from table
3)Create a table and store the data in the table. Use the table in SAP to extract the data.
BAPI won't work without any parameters, you have to pass some parameters then the BAPI will return some values.
Hope i am clear.
Thanks&Regards,

Need a VB-Script that read a txt-file and only the lines that are new since last time

Hi,
I need help to write a VB script that read all new lines since the last time.
For example: The script reads the textfile at specific time, then 10 minutes later the script read the file again, and it should now only read the lines that are new since last time. Anyone that has such a script in your scriptingbox?
cheers!
DocHo
Doc

Based on the excellent idea by Pegasus, where is a VBScript solution. I use a separate file to save the last line count read from the file, then each time the file is read I update the line count. Only lines after the last count are output by the program:
Option Explicit
Dim strFile, objFSO, objFile, strCountFile, objCountFile, strLine, lngCount, lngLine
Const ForReading = 1
Const ForWriting = 2
Const OpenAsASCII = 0
Const CreateIfNotExist = True
' Specify input file to be read.
strFile = "c:\Scripts\Example.log"
' Specify file with most recent line count.
strCountFile = "c:\Scripts\Count.txt"
' Open the input file for reading.
Set objFSO = CreateObject("Scripting.FileSystemObject")
Set objFile = objFSO.OpenTextFile(strFile, ForReading)
' Check if the line count file exists.
If (objFSO.FileExists(strCountFile) = False) Then
    ' Initial count is 0, so all lines are read.
    lngCount = 0
Else
    ' Open the line count file.
    Set objCountFile = objFSO.OpenTextFile(strCountFile, ForReading)
    ' Read the most recent line count.
    Do Until objCountFile.AtEndOfStream
        lngCount = CLng(objCountFile.ReadLine)
    Loop
End If
' Read the input file.
lngLine = 0
Do Until objFile.AtEndOfStream
    ' Count lines.
    lngLine = lngLine + 1
    strLine = objFile.ReadLine
    If (lngLine >= lngCount) Then
        ' Output the line.
        Wscript.Echo strLine
    End If
Loop
' Close all files.
objFile.Close
If (lngCount > 0) Then
    objCountFile.Close
End If
' Ignore last line of the file if it is blank.
If (strLine = "") Then
    lngLine = lngLine - 1
End If
' Save the new line count.
Set objCountFile = objFSO.OpenTextFile(strCountFile, _
    ForWriting, CreateIfNotExist, OpenAsASCII)
objCountFile.WriteLine CStr(lngLine + 1)
objCountFile.Close

How to read xml file that has changing element names?

Idon't know much about xml, nor reading it with java, but I have this problem with reading xml file. The file something like this:
<configuration>
 <DEV001>
 <serial>001</serial>
 <id>number 1</id>
 </DEV001>
 <DEV002>
 <serial>002</serial>
 <id>number 2</id>
 </DEV002>
</configuration>I have imported the org.w3c.dom.* api, that I use for parsing. I don't know is this a generic or a parser specific issue, but how can I get all the nodes starting with "DEV" into a NodeList?
If you know a solution for this with another parser, please share it. I have no reason to use that specific parser, I just found a sample using that.
kari-matti

Well, NodeList is an interface, so you cannot construct one and put the "good" elements into it. But, you might be able to cast the NodeList with all of the children of the root into an IIOMetadaNode (which is the class that implements the NodeList interface. That class has a removeChild() method that might be able to remove the text nodes and any that don't start with DEV.
But, if you remove nodes, and still want to do things with the full DOM Document, be very careful and run tests. It may remove those nodes from the full Document.
If, on the other hand, the printingData( Nodelist nl) method could be modified so it takes an ArrayList or some other collection, it is very simple.
Just create an ArrayList, and when you find an element starting with DEV, add it to the ArrayList. When you are done, process that list and you are finished.

UCCX Reading XML file hosted on IIS web server

hi guys,
i have a customer on CCX 8.5 environment and they have a .NET application running on an IIS web server. As part of this .NET application, the app produce an XML file.
My questions is
"Can CCX read XML file that is hosted externally on IIS web server rather than parsing the XML file on CCX document repository?"
All of the examples of XML parsing points to the XML file in document repository.
Any pointers to links and documentation/example on how to do this would be greatly appreciated.
If this is not achievable, if you could kindly suggest a different way of doing it too would be greatly appreciated.
Thanks in advance,
Daniel

Hi,
to be quite honest with you, I don't know anything about Sharepoint - so I am afraid I cannot help you with its XML editing capabilities. XML is just a well formed text file that follows some logical rules, so no additional application is required for editing, in fact, I always encourage everybody to use Notepad/Textpad/ to read and edit XML files. Of course, if it's not possible, you will find a great number of various user friendly XML editing applications.
A UCCX script will normally access an XML using the Create URL Document step and then, using the Get XML Document data step with the help of an XPath expression, will filter out the necessary information from the XML document.
The protocols used are standard and well known, including HTTP and XPath (and XML itself). So it does not really matter what kind of HTTP server serves the XML file, IIS is just an option.
Examples may be found in the Scripting guides for your particular UCCX version.

Newbie help please: "Validation of XML file failed."

Hopefully my question is short and easy.
I'm a developer and haven't used FrameMaker before. However for unforeseen reasons, I've inherited our technical help documentation constructed in FrameMaker which I've never used. Unfortunately I'm under a very tight deadline and I'm attempting to update our already existing and fairly extensive application help files.
However, I'm getting a "Validation of XML file failed" error for 90% of our .xml help docs. I opened our .book file in FrameMaker fairly easily, and can see all of our .xml files. However the variables already embedded in the documents aren't being recognized and seem to be causing the above error. I've located our variable definition files (xml) in the concepts folder, but FrameMaker doesn't seem to recognize them. Any suggestions on what I can check or how I can get FM to refer to the variable definitions? I'm working with a new installation of FM, is there some setup I overlooked?
Many thanks,
dana.

Sheila and Rick,
Thank you both so much for your offer of help. My apologies for not replying earlier. Other 'emergencies' and priorities at work took me in other directions. It turns out another solution has been found for the time being. But thank you again for your replies. They say a lot about this community and its support. :)
Thanks again,

Problem while reading XML File from Memory

I want to read the data from an XML File which is residing in memory.The XML File should be read not by the name or the location of the file but by a Response String.
So Can anybody help me out how can get this.
I tried it with BufferedInputStream but BufferedInputStream needs InputStream as a Parameter and i am not able to get what parameter should be passed into the BufferedInputStream as the syntax of this is
BufferedInputStream(InputStream in)
Its very Urgent !!!
Thanks in Advance

I have created the parsing method.
The code is like this.
if(response.toString().equals("CS_NEWS_RESPONSE"))
*//InputStream in = new BufferedInputStream(InputStream());*
*//InputStream in = new BufferedInputStream(response.toString());*
*//BufferedInputStream b = new BufferedInputStream(in);*
DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory.newInstance();
DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder();
Document doc = docBuilder.parse(in);
Element root = doc.getDocumentElement();
The code will go like this....
response.toString() is containing the response type which is the identification of that particular XML File. By using this my file is identified and after identification of this file, i should read the contents and parse them.
Sentences in the bold are the ways. Is this the correct way ??
Amit Will you be able to help me or is there anybody else who knows about this.
