catch (Exception e) { }
E) byte [] b = baos.toByteArray();
try { recId = rs.add(b, 0, b.length); }

5. Given:
a JAR containing a MIDlet named TesterMIDlet
a JAD with this content:
CertificationExam: Sun Certified Mobile Application DeveloperMIDlet-1: TesterMIDlet, , certification.TesterMIDlet MIDlet-Jar-Size: 2038 MIDlet-Jar-URL: Certification.jar MIDlet-Name: Certification MIDlet-Vendor: A Testing Company MIDlet-Version: 1.0 MicroEdition-Configuration: CLDC-1.0

B) String ExamName = System.getProperty("MIDlet-CertificationExam");
C) String ExamName = System.getProperty("CertificationExam");
D) String ExamName = this.getAppProperty("MIDlet-CertificationExam");
