Posted on Dec 10, 2004 at 03:29 PM 12 Views

Hello,

I have th following code:

...

...

public void doContent(

IPortalComponentRequest request,

IPortalComponentResponse response)

{

IResource aResource = null;

ResourceContext rContext = new ResourceContext(aUser);

RID aRid = new RID("/documents/test/myfile.xml");

try

{

IResourceFactory aResourceFactory = ResourceFactory.getInstance();

aResource =

ResourceFactory.getInstance().getResource(aRid, rContext);

IContent con = aResource.getContent();

}

catch (AccessDeniedException ex)

{

ex.getLocalizedMessage();

}

catch (com.sapportals.wcm.repository.ResourceException ex)

{

ex.getLocalizedMessage();

}

}

...

...

...

myfile.xml has just a line like "test"

How could I read the myfile.xml content ? I want to get the above string.

Thanks for any feeback

    Hi Altafin,

    1.) Just for the code being beautiful: Replace RID aRid = new RID("/documents/test/myfile.xml"); by RID aRid = RID.getRID("/documents/test/myfile.xml");

    2.) 

    InputStream xmlIS = con.getInputStream();
BufferedReader br =
    new BufferedReader(new InputStreamReader(xmlIS));
String yourLine = br.readLine();
br.close();

    etc. pp.

    Hope it helps

      Hi Altafin,

      sorry, a small mistake in my code: readLine() only reads lines ending with cr/lf/cr-lf.

      So if the one (last) line is not guaranteed to end by one of these codes, code is a bit more complex (but now also complete file is read, for your convenience):

      InputStream xmlIS = con.getInputStream();
ByteArrayOutputStream out = new ByteArrayOutputStream();
byte[] buffer = new byte[4096]; // as you like
int bytesread = 0;
while ((bytesread = in.read(buffer)) != -1) {
  out.write(buffer, 0, bytesread);
}
String myFile = out.toString("UTF-8"); // as saved

      Hope it helps
