Hej

Jeg har et problem med en Servlet som via RMI kontakter en java applikation
kørende på en anden maskine. Hvis koden køres i en servlet opstår fejlen,
mens hvis den køres som almindelig applikation kan det fint køre. Servletten
køres i en Tomcat 4.1. Der benyttes JDK 1.3.1.

Udsnit af koden:

// FORBINDELSE TIL REMOTE OBJEKT remoteDiasNet1 oprettet
// get the file PeterPan.pdf from the user test:
PatientData patientData = remoteDiasNet1.loadPatientData("PeterPan.pdf",
"");
System.out.println("patientdata er hentet");

System.out.println("before guiData");
// insert patientdata in model
GuiData guiData = remoteDiasNet1.insertPatientData(new PatientData());

System.out.println("after guiData");

}
catch( Exception ex ) {
System.out.println("before getmsg");
System.out.println(ex.getMessage());
ex.printStackTrace();
}

Følgende fejl opstår under kørsel i servletten:

patientdata er hentet
before guiData
before getmsg

Hvor kommer den URL fra? PatientData? Prøv file:///C:/Programmer/Apache
(tror jeg, ikke sikker på om det er /C:/ eller /C/).
