I have the following code:

    URL u = null;
    try
    {
      String isapiurl = m_ISAPIURL + "?AccessMode=GET" + "&CompanyName=" + 
     m_CompanyName + "&Category=" + m_Category + "&";
      u = new URL(isapiurl);
    }
    catch(MalformedURLException e)
    {
      m_URLContent = "URL not specified correctly";
    }

    try
    {
      if (u != null)
      {
        byte b[] = new byte[10000];

        u.openStream().read(b);

        int i;

        m_URLContent = new String(b, "8-bit");

m_URLContent is a String.  As you can see it opens a URL connection to a
site with some parameters.  It then uses openStream to read the response. 
I then want to take the response, which comes in the form a byte, and
convert it to a String.  The String constructor I used to use was the
String(b, 0) which has since been depreciated.  I decided to try the new
character encoding version, but do not know what the valid encoding strings
are.

Can someone either tell me an easier way to open a URL connection and read
the response into a string or what the posible character-encoding strings
are?  If the latter, I especially need the one to convert from byte to
string.

thanks, Tony
