Subject Re: Httpclient under weblogic 7.0
Date Wed, 28 May 2003 02:25:46 GMT
Here is the modified example from weblogic:

package examples.security.sslclient;

import java.io.File;
import java.net.URL;
import java.io.IOException;
import java.io.InputStream;
import java.io.FileInputStream;
import java.io.OutputStream;
import java.io.PrintStream;
import java.util.Hashtable;
import java.security.Provider;

import javax.naming.NamingException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.servlet.ServletOutputStream;

//import com.sun.net.ssl.internal.www.protocol.https.*;
//import com.sun.net.ssl.*;

import weblogic.net.http.*;
import weblogic.jndi.Environment;

import org.apache.commons.logging.*;
import org.apache.commons.httpclient.*;
import org.apache.commons.httpclient.methods.*;


public class SSLClientTest {


  public static void main (String [] argv)
    throws IOException {
    try {

      testURLConnect();


    } catch (Exception e) {
      e.printStackTrace();
      System.out.println("----");
    }

  }
public class SSLClientTest {


  public static void main (String [] argv)
    throws IOException {
    try {

      testURLConnect();


    } catch (Exception e) {
      e.printStackTrace();
      System.out.println("----");
    }

  }


  public static void testURLConnect()
  {

    try
    {
System.setProperty("org.apache.commons.logging.Log",
"org.apache.commons.logging
.impl.SimpleLog");
System.setProperty("org.apache.commons.logging.simplelog.showdatetime",
"true");
System.setProperty("org.apache.commons.logging.simplelog.log.httpclient.wire
", "
debug");
System.setProperty("org.apache.commons.logging.simplelog.log.org.apache.comm
ons.
httpclient", "trace");

        // set protocol handler
      java.util.Properties p = System.getProperties();
      String s = p.getProperty("java.protocol.handler.pkgs");
      if (s == null) {
        s = "weblogic.net";
      } else if (s.indexOf("weblogic.net") == -1) {
        s += "|weblogic.net";
      }
      p.put("java.protocol.handler.pkgs", s);
      System.setProperties(p);
        String url_str = "https://www.dell.com/us/en/gen/default.htm";
        URL url = new URL(url_str);

        System.out.println("Use Weblogic classes");
        //-------------------------------
        // try weblogic apis first
      weblogic.net.http.HttpsURLConnection sconnection =
        new weblogic.net.http.HttpsURLConnection(url);


        sconnection.connect();
        System.out.println("WLS api returned: " +
sconnection.getResponseCode());
        sconnection.disconnect();

        System.out.println("Use HTTPClient classes");
        //-------------------------------
        // next try httpclient apis
        GetMethod get = new GetMethod(url_str);
        org.apache.commons.httpclient.HttpClient httpclient = new
org.apache.comons.httpclient.HttpClient();
        int result = httpclient.executeMethod(get);

        System.out.println( "Returned::" + result );
        get.releaseConnection();

    } catch (Exception ioe) {
      ioe.printStackTrace();
    }
  }
}


The trace when I run the above program is as follows (note that weblogic
apis return 200).
