Ich bin echt am verzweifeln. Ich habe das Beispiel aus dem Video2Brain JavaEE benutzt. In den Kapiteln wird weder etwas in jndi.properties eingestellt, noch ein Local Interface erstellt. Selbst das Beispielprogramm der DVD funktioniert nicht. Was kann hier denn noch das Problem sein?
Am liebsten würde ich fluchen um mir wenigstens etwas Frust von der Seele zu schreien.
