Exception while trying to read a file from applets

Posted: Mar 19, 2002 6:23 PM

Hi everybody

I'm programming a system with an applet. I need to read a text file from the applet and I have this exception:

Exception occurred during event dispatching:
com.ms.lang.VerifyErrorEx: controlador.Leer: recursive jsr
at controlador.validar
at interfaz.Validar
at interfaz.actionPerformed

Controlador is the class where I have the method Leer (reading the file from an URL).

This is the Method that I think it has problems:

public Vector Leer(String arch){
URL archivoP;
String registro;
InputStreamReader isr;
BufferedReader lector;
StringTokenizer tok;

Vector archivo = new Vector();

try{
archivoP = new URL("http://vigia.ens.uabc.mx/~al304371/proyectos/poo/" + arch);

isr = new InputStreamReader(archivoP.openStream());
lector = new BufferedReader(isr);
lector.readLine(); //Menu del archivo.
registro = lector.readLine();
archivo.addElement(registro);
lector.close();

}catch(Exception e){
System.out.println("Fallo en lectura :"+ e.toString());
}finally{
return(archivo);
}
}

If you know what's the problem I'll appreciate a lot your replies.

Thank you!

Hi, This is me again.

My friend Julio who also is member of this Forum (jfonseca) and my CS classmate helped me to solve the problem :).

It was a problem caused by the security of the JVM of the first server where I implemented my applet.

So, we moved the applet to a different server and it worked. Then we realized that it was a server JVM's problem.

Thank you!
