problem with InputStreamReader

[vitaly87]

Hello all!
I have a function search(String target) that return me the correct link that I need.
I use this link for this function

public static String  htmlContentParser(URL address) throws MalformedURLException, IOException{
String sourceLine;
                String content = "";
 
                // The URL address of the page to open.
                
 
                // Open the address and create a BufferedReader with the source code.
                InputStreamReader pageInput = new InputStreamReader(address.openStream());
                BufferedReader source = new BufferedReader(pageInput);

But get error on:
InputStreamReader pageInput = new InputStreamReader(address.openStream());

The errors are:
Exception in thread "main" java.io.FileNotFoundException: http://www.gsmarena.com/samsung galaxy-3294.php
at sun.net.http://www.protocol.http.HttpURLConn...tion.java:1311)
at java.net.URL.openStream(URL.java:1010)
at datamining.html.extratorNodes.htmlContentParser(ex tratorNodes.java:116)
at datamining.html.extratorNodes.<init>(extratorNodes .java:41)
at datamining.html.getTraningDate.main(getTraningDate .java:34)

when I dont use search(target) and sent to htmlContentParser the link manually it's all work fine.
Why is that?

the code of search is:

public  String search(String target) {
//Convert the target to lowerCase
    target=target.toLowerCase();
if (target.length()==0)return "model is empty";
target = target.trim( );
//QueryString query = new QueryString("search", target);
try
{//Open the URL for reading
  URL address = new URL("http://www.gsmarena.com/results.php3?sQuickSearch=yes&sName=" + target);
 
System.out.println("the links to search is: " +address);
//Get links from the page,links-all the links from the correct page
HTMLLinkExtrator links = new HTMLLinkExtrator();
ArrayList correctLinks = new ArrayList();
links.LinkExtrator(address.toString());
 
 
 
 
   InputStream in = new BufferedInputStream(address.openStream());
    // Chain the InputStream to a Reader
    InputStreamReader theHTML = new InputStreamReader(in);
    //System.out.println(StreamToString(theHTML));
 
 
 
    //Find in the links the target word like (iphone 4)-->(iphone_4)
correctLinks=links.findCorrectLinks(target.replaceAll(" ","_"),links.listLinks);
 
 
//If the model(target) not found the print empty
   if (correctLinks.isEmpty()) System.out.println("the correctLinks is empty ");else
   {
//ModelId is the id of the model in the web http://www.gsmarena.com/
   String modelId=links.link(correctLinks.get(0).toString(),"-",".php");
   if ((modelId.length()!=0)){
   //Creating the link for the model
  URL corectModel = new URL("http://www.gsmarena.com/"+target+modelId+".php");
  //Return the correct link of the target model
 System.out.println("the correct link of model is: "+correctLinks.get(0));
 theHTML.close();
 in.close();
  return corectModel.toString();
    }else  System.out.println("not found");}
//System.out.println("the first link: "+correctLinks.get(0));
}
catch (IOException e)
{
    System.err.println(e);
}
 
return "not found";
}

thanks a lot

i think the problem is the space between samsung and galaxy !
replace it with '+' sign, or use URLEncoder.encode.

URL address = new URL("http://www.gsmarena.com/"+URLEncoder.encode("samsung galaxy-3294.php", "UTF-8"));

works fine.
