I really have done this before, but this is throwing me curves that I
can't quite figure out. Here's the link I'm trying to create:
http://orgmeta.xmlsweb.com:3245/orgs.xml?
And here's the code I'm using...
StringBuilder sb;
String host="orgmeta.xmlsweb.com";
CgiProcessor cgi=new CgiProcessor(host,3245,true);
BufferedReader br;
try
{
br=new BufferedReader(new InputStreamReader(
cgi.get("orgs.xml","")));
} catch (heavyweight.Exception he)
{
throw new IOException(he.toString());
}
String str;
while((str=br.readLine())!=null)
{
System.out.println(str);
}
File[] imgs=imgPath.listFiles();
return imgs;
And the class that uses:
