Listing Folders From WebFOCUS

Topics:

Visual Basic .NET Example
Java Example
HTML and jQuery Example

This section provides code examples that demonstrate how to retrieve a list of the top-level folders from WebFOCUS. A successful sign-on request is a prerequisite for running this example, including retrieving the HTTP Header cookies from its response.

Visual Basic .NET Example

Imports System.Net
Imports System.IO
Imports System.Text
Dim request3 As HttpWebRequest
Dim response3 As HttpWebResponse
Dim webStream3 As Stream
Dim webResponse3 As String = ""
Dim tempfile As String
request3 = WebRequest.Create("http://localhost:8080/ibi_apps/rs/ibfs/WFC/
Repository?IBIRS_action=get")
request3.Method = "GET"
'cookies is defined as CookieContainer in the Signing-On to WebFOCUS example
request3.CookieContainer = cookies
response3 = request3.GetResponse()
webStream3 = response3.GetResponseStream()
Dim webStreamReader3 As New StreamReader(webStream3)
tempfile = "c:\temp\Folders.xml"
FileOpen(1, tempfile, OpenMode.Output)
While webStreamReader3.Peek >= 0
     webResponse3 = webStreamReader3.ReadToEnd()
     PrintLine(1, webResponse3)
End While
FileClose(1)
Dim xmlElem = XElement.Parse(webResponse3)

Java Example

import java.awt.Frame;
import java.io.BufferedReader;
import java.io.File;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import org.apache.commons.httpclient.*; 
import org.apache.commons.httpclient.methods.*;
String request3 = "http://localhost:8080/ibi_apps/rs/ibfs/WFC/Repository?IBIRS_action=get";
						
GetMethod method_getFolders = new GetMethod(request3);
// cookies is defined as Header[] in the Signing-On to WebFOCUS example			
for(int h=0; h<cookies.length; h++){
       method_getFolders.addRequestHeader(cookies[h].getName(), cookies[h].getValue());
}
// client is defined as HttpClient in the Signing-On to WebFOCUS example 			
int statusCode3 = client.executeMethod(method_getFolders);
					
InputStream rstream3 = null;
rstream3 = method_getFolders.getResponseBodyAsStream();
File tempfile = new File("c:\\temp\\Folders.xml");
FileOutputStream fos = new FileOutputStream(tempfile);
PrintWriter out=new PrintWriter(fos);
BufferedReader br3 = new BufferedReader(new InputStreamReader(rstream3));
String line3;
String newOutput = null;
while ((line3 = br3.readLine()) != null) {
	newOutput = line3;
	out.println(newOutput);
	System.out.println(line3);
}
br3.close();
out.close();
