Read XML file from KM location

[chinna_babu2]

Hi Experts,

Does any one have the idea about reading the XML file from the KM location.

I have a Web Dynpro running in portal, which reads the XML file from within Web Dynpro server's location.

For this I am using java.io.File and DOM parser to read the XML file. But now my iView needs to read this XML file KM.

I found some api's in SDN to be used to access the KM files

bc.rf.framework_api.jar

bc.rf.global.service.urlgenerator_api.jar

bc.sf.framework_api.jar

bc.util.public_api.jar

Can any one please provide me the sample code to access XML file.

Thanks in Advance

Chinna.

Hi,

Following document explains how to access KM from Wd

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/user-interface-tec...

Once the document is available in Webdynpro. Use the DOM or SAX to parse it and load the values to respective context attribute.

Hi Ayyapparaj,

I followed the docuement and tried to run the demo application. When I run the application, it is throwing

java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/clientserver/uielib/standard/api/IWDAbstractTableColumn exception. I did set the class path of all the jar files, even then it is giving this error.

I have deleted the Table control and run the application with static document location. It is finding the resource location.

Because I know the path of the document in design time itself, I can fix the path of the document. As shown in the below code.

wdComponentAPI.getMessageManager().reportSuccess("in refreshtable");
        IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
        com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
      //create an ep5 user from the retrieved user
       IUser ep5User = WPUMFactory.getUserFactory().getEP5User(sapUser);
      //establish resource context
       IResourceContext resourceContext = new ResourceContext(ep5User);
      //get a resource factory
      IResourceFactory resourceFactory = ResourceFactory.getInstance();
 //get a RID from the current path to display the according content
     //RID pathRID = RID.getRID(wdContext.currentContextElement().getPath());
     RID pathRID = RID.getRID("/documents/TestFolder/Test.xml");

But my problem is, because I am using the java.io.File stream and DOM object to parse the XML file in my existing iView, I want to use the reading part as it is as shown in below. code

File file = new File("Test.xml");//Which picks up from server location
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(file);

Can you please give me some suggestions on how to approach

Thanks,

Chinna

HI

This exception indicates that you run an application on a Web AS where the interface IWDAbstractTableColumn does not exist (e.g.a NW04 server).

Probably you deployed an application created with NW04s (7.0) on a NW04 (6.40) server.

Also try to put required jar file into lib folder of your application

thanks

Hi Anup Bharti,

You may be exactly correct because I have deployed this application on WAS 6.4.

But, here my requirement is not to recurse the folders/files inside the KM. I have an XML file, where I know the path in design time itself.

I am using DOM parser to parse and read the XML file and for this parser I can feed either java.io.File path or Input stream.

Could please give me some suggestions for the above approach.

Thanks,

Chinna.

try this

DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();

DocumentBuilder db = dbf.newDocumentBuilder();

Document doc = db.parse("http://localhost:8084/XmlApplication1/sss.xml");

String name = "Banglore";

NodeList nlst = doc.getElementsByTagName("name");

Node node= nlst.item(0).getFirstChild();

// Node nod2=node.getFirstChild();

node.setNodeValue(name);

}

catch(Exception e)

{

out.println(e) ;

}

Hi All,

My issue has been solved with the following piece of code

IResourceContext resourseContext = new ResourceContext(ep5User);
          com.sapportals.wcm.repository.IResource resource = ResourceFactory.getInstance().getResource(rid, resourseContext);
         DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
         DocumentBuilder db = dbf.newDocumentBuilder();
         Document doc = db.parse(*resource.getContent().getInputStream()*);
        doc.getDocumentElement().normalize();

Thanks for all your replies.

Chinna.
