Hallo Community,

ich bin gerade dabei unser Service Modul in ein Maven-Projekt umzubauen.

Vorgegangen bin ich nach folgender Anleitung

FS Module mit Maven2 bauen

Das Projekt lässt sich auch bauen und installieren. Erhalte jedoch beim Aufruf der Konfiguration im ServerManager folgenden Fehler

ERROR 16.02.2017 09:55:38.293 (de.espirit.firstspirit.client.AbstractGuiHost): ExceptionHandler.uncaughtException() -

Hallo Hüseyin

ich habe mir nun gerade nicht dein ganzes Posting durchgelesen, aber ich nutze diese Stelle mal um Werbung für den FSM package type zu machen:
GitHub - zaplatynski/fsm-packagetype: A simple approach to a Maven package type for FirstSpirit modu...

Vielleicht macht der auch für euch die Entwicklung leichter.

Hallo Hüseyin,

vielleicht hilft auch das hier:

FirstSpirit Maven Artifacts for external use (Release 1.1)

Viele Grüße,

Raphael.

[HSener]

Hi Raphael,

danke für den Hinweis.

Mein Problem ist eher die GUI die sich nicht öffnen lässt, denn ohne GUI funktioniert das Maven-Modul.

Gibt es denn kein Beispiel Projekt eines Service Moduls, das mit Maven erstellt worden ist?

Gruß

Hüseyin

[rrichter]

Hi Hüseyin,

das hängt sicher nicht damit zusammen, dass es ein Service-Modul ist. Dass sich ein fsm bauen lässt, ist noch kein Garant dafür, dass das Modul dann auch fehlerfrei im Servermanager funktioniert.

Hast du denn mal in Zeile 150 geschaut, wo hier ein Null-Wert vorkommen kann, der anscheinend nicht abgefangen wird?

de.kittelberger.module.service.ServiceProviderConfigPanel.initGuiValues(ServiceProviderConfigPanel.java:150)

[HSener]

Hallo Raphael,

in Zeile 150 wird die GUI mit dem Feld _textGuiField befüllt

private void initGuiValues() {
     _textGuiField.setText(_config.getTextGuiField().toString().trim());
}

Ist es möglich, dass er die Config-Datei nicht einlesen kann?

Gruß

Hüseyin

[marza]

Hallo Hüseyin,

ich denke, dass es schon helfen könnte, wenn Du aus Deiner Zeile 150 mehere Zeilen Code machst, um eine Chance zu haben, die NullPointerException einzugrenzen.

Grüße

Marian

[thmarx]

Hallo Hüseyin,

an der Stelle können ja einige Sachen null sein:

_textGuiField.setText(_config.getTextGuiField().toString().trim());

_textGuiField, wurde das TextField richtig initialisiert?

_config, das Einlesen der Config musst du selbst machen, erzeuge vielleicht entsprechen Logs, damit du sicher sein kannst, dass es geklappt hat

_config.getTextGuiField(), kann es sein, das beim ersten Aufruf ein null zurück kommt, es wurde bis jetzt ja noch keine Config gespeichert.

Viele Grüße

Thorsten

[tenter]

Hallo Hüseyin,

Konnten dir Raphael, Marian und Thorsten weiterhelfen? Über einen neuen Stand zu deinem Problem würden wir uns freuen

Grüße,

Hannes

[HSener]

Hallo Hannes,

bin derweilen noch nicht dazu gekommen weiter am Modul weiterzumachen.

Sobald ich wieder zeitlich wieder dazu komme, werde ich hier berichten.

FYI thmarx​ & marza​
