Reading XML file from java web service

Hi
I am developing web service using Netbeans and the application server is glassfish.
but I am facing a problem
I have folder called "config" which will include the xml files. What I need to do setting path into that folder
but it will read from another location when I am deploying it
How to set our own path ?

I didn't quite get what the problem is but if the the desired file is in custom directory why don't you just use absolute path to reference it?
Like: "/home/my/OSconfig/MConfig.xml"

Reading an xml file in the web services java file

I want to read some data in the webservices file.so i am writing my own xml file through which i want to read data.but i am not able to read xml file from web services file.also , i am not able to put xml file in the .ear file,as there is no such tag in servicegen script through which i can add xml file in the .ear file.
i know in case of servlets,i will specify context-param attributes in web.xml,and i can access those in my servlet.can i do anything like this for webservices,and i am not using any servlets for web services.
kindly tell any solution.

One possible option to parse an xml-file to a flex XML object:
public function parseConXML(source:String):void
                xmlLoader = new URLLoader();
                xmlLoader.load(new URLRequest(source));
                  // Eventlistener: if URL loaded --> onLoadComplete function
                  xmlLoader.addEventListener(Event.COMPLETE, xmlLoadComplete);
            public function xmlLoadComplete(evt:Event):void{
                var xml:XML = new XML();
                 // ignore comments in XML-File
                XML.ignoreComments = true;
                   //ignore whitespaces in XML-File
                 XML.ignoreWhitespace = true;
                // XML-Objekt erstellen
                xml = new XML(evt.target.data);
               //AFTERWARDS use your xml as your wish

Open a local file from a web Service

Hello!
Likely this is a trivial question, but I need to open a local file from a Web Service and i don't know how to get the file path. I mean that I have a WS source code placed in a proper package (my.ws.package) with an additional configuration XML file placed in the same directory. I need to read it, but if I use merely
File conf = new File("Conf.xml");it can't find it. I've tryed with:
MyWS.class.getClass().getProtectionDomain().getCodeSource().getLocation().getPath()in order to get the file path, but a
java.security.AccessControlException access denied (java.lang.RuntimePermission getProtectionDomain)arises...
I don't know...
Suggestions?
Thanks.

Is there any way to read XML directly from a Web Page ??

i have a url, which on sending request, shows XML in browser.
Now i need to read this XML in browser and then manipulate it according to my need and display it on another page.
actually the process is. :
1) i have to first retrieve an xml from other site. (XML will only be shown in browser)
2.)then i have to read the Xml and show it in according to my requirements.
Is there any way to read XML directly from a Web Page ??
is their logic to accomplish this.
e.g in Servlet i can do somewhat like this :
String wholeXml=Somemethod(url);
Please Advice

the average Java XML parser will accept an InputStream, so just open an URLConnection to the webpage, get the inputstream from it and feed that inputstream to the XML parser. If the URL has valid XML data, it will get parsed without problems.

Hi all
i am able to create XML file with the sample data as below from java programming.
i need sample code on how to edit the existing data in the XML file?
for example
<?xml version="1.0"?>
   <mydata>
           <data1>
                     <key1>467</key1>

But i would like to know if there is any thing in java core classes,
I have seen XMLEncoder, but this is not what i want.
Any ideas

How to modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

FM to read XML files from Application server in ECC5.0

Hi All,
We need to pick up an XML file from Application server/FTP server. The requirement is to parse the XML file and process it to create material master. SAP provides standard function modules to read XML files.
Now we need to read the XML file contents of MM01 and upload into SAP Data Base through BAPI
I need to know about the Function modules to read XML files from Application Server and also about the FM's that will update the Date base tables with the data obtained form XML files.
Regards
Prathima

Parsing XML data:
http://help.sap.com/saphelp_nw04/helpdata/en/86/8280ba12d511d5991b00508b6b8b11/frameset.htm
or alternatively check out ABAP online help for "CALL TRANSFORMATION".
For creating the material master look at BAPI_STANDARDMATERIAL_CREATE.

Reading XML file from application server and put into internal table-4.6C

Dear All,
Is there any way of reading XML file from application server to SAP? I am using 4.6C. Function module SCMS_STRING_TO_XSTRING function module is not available. Please suggest.
Thanks and regards,
Atanu

Hi Atanu!
Simply use the XSLT transformation 'ID'.
FIELD-SYMBOLS <ls_result> TYPE ANY.
CREATE DATA lref_data TYPE (your_structure).
ASSIGN lref_data->* TO <ls_result>.
CALL TRANSFORMATION id
SOURCE XML xmlstr
RESULT result = <ls_result>.
"xmlstr" contains your XML file. Just read it into it via standard I/O operations. "<ls_result>" will contain your DDIC formatted content.
Best regards

How I can create a XML file from java Aplication

How I can create a XML file from java Aplication
whith have a the following structure
<users>
<user>
<login>anyName</login>
<password>xxxx</password>
</user>
</users>
the password label must be encripted
accept any suggestion

Let us assume you have all the data from the jsp form in an java bean object..
Now you want a xml file. This can be acheived in 2 ways
1. Write it into a file using java.io classes. Say you have a class with name
write("<name>"+obj.getName+</name>);
bingo you have a flat file with the xml
2. Use data binding to do the trick
will recommend JiBx and Castor for the 2nd option
