Geachte lezer,

ik heb de volgende code aangepast en krijg hem niet werkend, hij zegt bij de eerste regel dat hij een semicolon verwacht maar dit is volgensmij niet het geval.

is er iemand die ziet wat er fout is?

PHP:

WebFile file = new WebFile( "http://voorbeeld.com" );
String MIME    = file.getMIMEType( );
Object content = file.getContent( );
if ( MIME.equals( "text/html" ) && content instanceof String )
{
    document.page.html.value = (String)content;
    
}

/**

 */
public final class WebFile {
    // Saved response.
    private java.util.Map<String,java.util.List<String>> responseHeader = null;
    private java.net.URL responseURL = null;

Bij voorbaat dank.

Code:

WebFile file = new WebFile( "http://voorbeeld.com" );
String MIME    = file.getMIMEType( );
Object content = file.getContent( );
if ( MIME.equals( "text/html" ) && content instanceof String )
{
    document.page.html.value = (String)content;
    
}

Moet na public class... komen..

ff editten want ik zat fout, maar het heeft idd te maken met de verkeerde positie van je eerste lijnen.

Oké, dit werkt (er staat wel een deeltje in comment want ik zit achter een proxyserver)

				System.out.println("1: "+MIME);
				Object content = file.getContent( );
				System.out.println("2: "+content.toString());
			} catch (MalformedURLException e) {
				e.printStackTrace();

Bedankt voor jullie antwoorden, ik had het ook in die volgorde geprobeerd.

de laats geposte code heb ik zojuist geprobeerd maar ook daar krijg ik een foutmelding:
