In der Java-Web-Service-Entwicklungsumgebung generieren Entwickler immer ein Testzertifikat mit "keytool". Während des Client-Tests wird der Web-Service-Test-Client häufig die folgenden Fehlermeldungen erhalten:
-
link://webservices/jax-ws/java-security-cert-certificateexception-no-name-passende-localhost-found/[java.security.cert.CertificateException:
Kein passender Name für localhost gefunden]. link://webservices/jax-ws/suncertpathbuilderexception-ungültiger-zertifizierungspfad-zum-angefordertes-ziel/gefunden[SunCertPathBuilderException:
Es wurde kein gültiger Zertifizierungspfad für das angeforderte Ziel gefunden.]
Hier ist ein Quellcode, den ich aus dem Buch kopiert habe: Java Web Services: In Betrieb genommen, 1st Edition von Martin Kalin . Ein sehr nützlicher Code in der Testumgebung NUR ** , zu studieren und als Lesezeichen für zukünftige Referenz zu empfehlen.
