Hi all,

I need to get the proxy setting details before accessing any url using URL class (java net package).

In jdk 1.5 there is a class called ProxySelector, which is supposed to do the job. But it is failing.

Below is source code iam trying

package com.httpclient;

import java.io.BufferedInputStream;
import java.io.BufferedReader;
import java.lang.reflect.Type;
import java.net.HttpURLConnection;
import java.net.InetAddress;
import java.net.InetSocketAddress;
import java.net.Proxy;
import java.net.ProxySelector;
import java.net.URL;
import java.net.URLConnection;
import java.util.List;

public class testURL {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
BufferedInputStream in;

HttpURLConnection conn;
BufferedReader bin;
URL u;
String fileContents="";
try {
ProxySelector ps = ProxySelector.getDefault();
URL url = new URL("http://google.com");
URLConnection connection = url.openConnection();
List proxyList = ps.select(connection.getURL().toURI());


int len = proxyList.size();
System.out.println("size : "+ len);
for (int i = 0; i < len; i++) {
Proxy p = (Proxy) proxyList.get(i);
InetSocketAddress addr = (InetSocketAddress) p.address();
if (addr == null) {
System.out.println("MANUAL");
}

else {
InetAddress ip_addr = addr.getAddress();

int tcp_port = addr.getPort();
// Use the specified IP and port number as the proxy

System.out.println("IP ADDR " + ip_addr + "tcp_port " + tcp_port);
}
}

} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}

Please help on solving this issue. Immediate response will be of very useful.

I have a WSDL url.

I need to invoke the webservice with serviceName, portName and operation using simple java standalone program.

Can any one give me some example or some site which gives these details.

Can be any type of client.

i.e. Static stub, Dynamic proxy or DII

thanks in advance

Hi

I want to create a XML from the folder specified.
For example if i give c:\\ to my xml generator, the generator should generate an xml file containing all the folders and files recursively in the c:\\.

It will look some thing like this.


<?xml version="1.0" encoding="utf-8" ?>

<folder_root name="Passed folder name with complete path">

<folder name="A">

<folder name="B">

<folder name="C">

<file name="file2" />

</folder>

<file name="file3" />

</folder>

<file name="file1" />

<file name="file3" />

</folder>

</folder_root>

Wrap them in the corresponding wrapper classes (int -> Integer, char -> Character, etc.) and the reflection API will automatically unwrap them.


--------------------------------------------
Suppose i have

public void set(int i){
}

public void set(Integer i){
}

And if i wrap the primitive int into Integer wrapper, which of the above methods will be considered. Actually the second one. But i want the first method to invoke. Now how do i do it.

Service service = (Service) ic.lookup(java:comp/env/service/SDFWs);
servicePort = service.getPort(com.sdf.SDFWsSEI.class);

String targetNameSpace = "urn:SDFWs/wsdl"; // This target namespace from WSDL
// <definitions name="SDFWs" targetNamespace="urn:SDFWs/wsdl"

QName portName = new QName(targetNameSpace,"SDFWs");
HandlerRegistry registry = service.getHandlerRegistry();
if(registry != null){
List handlerList = new ArrayList();
handlerList.add(new HandlerInfo(ClientHandler.class,null,null));
registry.setHandlerChain(portName, handlerList);

cache.put(jndiHomeName, servicePort);
}


In the above snippet of code, iam getting NullPointerException at line

HandlerRegistry registry = service.getHandlerRegistry();

Not able to HandlerRegistry.

What could be the problem?

Please let me know if there is some problem the way oam registering the Handler.

thanks in advance.
