Ich erstelle eine RESTful-Anwendung und ich habe Probleme, eine Konvertierung für eine neue Verbindung. Mein Anwendungsserver ist Wildfly 10.0.ClassCastException zwischen gleichen Klassen Wildfly 10
Datasource und Treiber im Standalone-full.xml:
<datasource jndi-name="java:jboss/datasources/PostgreDS" pool-name="PostgreDS" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://192.168.0.112:5432/bdns</connection-url>
<driver>postgresql</driver>
<transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>40</max-pool-size>
<prefill>true</prefill>
</pool>

Können Sie Ihre Pom-Datei teilen? Was ist in deiner WAR-Datei? –
Also welcher Typ wird von 'ds.getConnection()' zurückgegeben? –
@JohnAment pom.xml wird hinzugefügt. –
