Hello,
The problem is that the URL constructor and the openStream method both
throw Exceptions (not Runtime Exceptions). You are not allowed to throw
non Runtime Exceptions in initializers.
You can, however, initialize the private members in an empty constructor.
There, you can either explicitly throw the two exception, or you can
catch the exceptions and deal with them appropriately.
See below for examples, and good luck,

Possibility 1:
--------------------------------------------------------------------------
package emailtools;
import java.io.*;
import java.net.*;
...
...
public class EmailBean {
...
...
private URL url = null;
private BufferedReader in = null;
public EmailBean() throws MalformedURLException, IOException {
url = new
URL("http://127.0.0.1:8080/examples/jsp/emailtools/test.jsp");
in = new BufferedReader(new InputStreamReader(url.openStream()));
}
}
--------------------------------------------------------------------------
Possibility 2:
--------------------------------------------------------------------------
package emailtools;
import java.io.*;
import java.net.*;
...
...
public class EmailBean {
...
...
private URL url = null;
private BufferedReader in = null;
public EmailBean() {
try {
url = new
URL("http://127.0.0.1:8080/examples/jsp/emailtools/test.jsp");
in = new BufferedReader(new
InputStreamReader(url.openStream()));
} catch (MalformedURLException e) {
throw new RuntimeException("Provided URL invalid");
} catch (IOException e) {
throw new RuntimeException("Unable to open URL input stream");
}
}
}
