Tomcat antwortet auf localhost:8080 auf einmal nicht mehr

[bastula]

Hallo Apache Freunde,

ich als blutiger Anfänger weiss nicht einmal, ob ich meine Frage ins richtige Forum eingestellt habe. Falls doch, hier ist sie:

Ich habe für eine Webanwendung einen bestehenden Tomcat benutzt und dort ein Servlet und diverse Java Klassen unter ../webinf/classes erstellt. Bis gestern lief alles wunderbar, doch heute startet der Tomcat nicht richtig. Wenn ich ihn anschmeisse, dann scheint er hochzufahren, ich kann einen ping auf 127.0.0.1 erfolgreich absetzen, aber unter http://localhost:8080/ bekomme ich die Fehlermeldung:

HTTP Status 404 - /

type Status report

message /

description The requested resource (/) is not available.

Ich habe in der Zwischenzeit definitiv nichts an der Konfiguration o.ä. geändert, das würde ich mich garnicht trauen.

Das logfile localhost-date.log hat beim letzten Startversuch folgenden Eintrag produziert:

Das sagt mir alles garnicht ... hat jemand einen Tipp für mich ?

VIELEN DANK im voraus,

[KingCrunch]

Also erstmal hat ein ping so ziemlich rein garnix mit einem Webserver zu tun. Es sagt dir nur, ob der Rechner im Netzwerk erreichbar ist. Und da ein Loopback (localhost/127.0.0.1) immer "im Netzwerk" erreichbar ist, ist allein ein ping da drauf etwas witzlos

Der Server scheint auch zu laufen, sonst würde er nicht mal nen 404 zurück geben. Was sagt denn das error.log vom Apachen?

Hi KingCrunch,

ich habe in der Zwischenzeit den Tomcat 5.0.28 neu installiert. Da lief mein Programm erst wieder, jetzt hängt er wieder. Auf die unter HTMLs, die im entsprechenden Verzeichnis /servlets-examples/ abgelegt habe, kann ich noch zugreifen, aber der Aufruf des servlets scheitert. Zugriff auf localhost:8080 auch, mit der gleichen Fehlermeldung wie gestern.

Die Datei localost.log hat als letzten Eintrag:

Die stderr.log ist leer. Kann das irgendwie ein Problem mit dem JRE sein ? Ich hab 1.4.2_09.

Ahnunglos: Bastian

[KingCrunch]

Bevor ich mich da jetzt durchwurschtele:

Was sagt denn das error.log vom Apachen?

[bastula]

HI,

wo liegt die Datei ? Ich hab nur das Verzeichnis ...\Apache Software Foundation\Tomcat 5.0\logs gefunden, da ist nur die stderr.log, und die wie schon gesagt ist leer.

Gruss & Dank,

Bastian

Hi KingCrunch,

ich habe noch etwas gefunden, beim TomCat Start macht er diese Meldung:

SCHWERWIEGEND: Skipped installing application listeners due to previous error(s)
16.03.2007 16:41:23 org.apache.catalina.core.StandardContext start
SCHWERWIEGEND: Error listenerStart
16.03.2007 16:41:23 org.apache.catalina.core.StandardContext start
SCHWERWIEGEND: Context startup failed due to previous errors

Irgendwas stimmt mit den listenern nicht, die sind wohl kaputt gegangen ... hast Du eine Ahnung, was da lost ist ?

DANK & Gruss,

Bastian

[KingCrunch]

Die vom Oberhäuptling sollten sich einfach im apache/logs-Verzeichnis befinden.

Hab vom Tomcat nu nicht so viel Ahnung, aber "due to previous errors" deutet ja eher darauf hin, dass der Fehler vorher auftrat ^^

Bin bei deinen Postings auch auf

Code: Select all

2007-03-16 13:15:30 StandardContext[]Error configuring application listener of class listeners.SessionListener

gestoßen, vielleicht hilft es dir nach Fehlern mit dem SessionListener zu googeln.
