[Ant, javac] Probleme beim compile mit Java5

Hallo Community,

wir haben es nun eindlich geschafft von Java 1.4 auf Java 5 umzusteigen. *pray*

Nur habe ich jetzt das Problem, dass mein build-script nicht mehr Fehlerfrei arbeitet. :(

Der javac-Task schmeißt während des Ablaufs folgende Info-Meldung:
Code: 
Note: Some input files use unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

Der Compile-Vorgang wird aber nicht abgebrochen.

Wenn der Tomcat das war-File entpackt, lockt er folgendes mit:
Code:

Weder mit der Infomeldung, noch mit demLogging kann ich etwas anfangen, zumal es unter Java1.4 problemlos ging und noch immer geht.

Kann mir einer von euch weiter helfen?
 
Erst einmal vielen Dank für deine Antwort.

Jetzt wo du es sagst... der läuft auch noch unter 1.4. :suspekt:

Das erklärt die Probleme beim Entpacken.

Was das Compilieren betrifft:
Seit Java5 werden Collection doch generisch (ich glaub das heißt so) deklariert, sprich:
PHP: 
List<Object> l = new ArrayList<Object>();

Da dies bei uns (noch) nicht der Fall ist, schmeißt der javac-Task diesen Hinweis. Dies lässt sich folgerndermaßen umgehen:
PHP: 
<javac srcdir="src" destdir="bin"  source="1.4" target="1.5">

Dass der Tomcat die gleichen Logs ausspuckt, liegt dann aller Wahrscheinlichkeit daran, dass dort noch immer die 1.4-Version läuft.
