Unable to deploy WebService in Weblogic 12c on LINUX

Question

Using JAX-WS we have developed a WebService and unable to deploy on WebLogic 12c running on LINUX JAVA 64Bit. However, same WAR file is deployed on WebLogic 12c running on Windows 7 using JAVA 32Bit and it works perfect. Here are the infos. Please let us know where / what could have gone wrong from our side. Thanks in advance

Thanks in advance and appreciate any help/hint.

Answer 1

Finally I found what was going on. It was basically misleading error log from WebLogic 12c. The problem was not related to <No Spring WebApplicationInitializer types detected on classpath> or java.lang.NoClassDefFoundError .

WebService class was getting instance of another class which in turn was loading properties (application.props) which was not found on the classpath. Instead of throwing NullPointer for prop file not found, system was showing different error message at WebService deployment.

Error was due to APP_PROP_FILE was not in any classpath

applicationProps.load(AppUtils.class.getClassLoader().getResourceAsStream(
                    APP_PROP_FILE));

Sample snippets

    static Properties applicationProps;
    public static synchronized AppUtils getInstance() {
        if (appUtils == null) 
            appUtils = new AppUtils();
        return AppUtils;
    }
    public AppUtils() {
        PropertyConfigurator.configure(System.getProperty("log4j.configuration"));
        loadProperties();
    }
    public static Properties getApplicationProps() {
        if (applicationProps == null)
            loadProperties();
        return applicationProps;
    }
    private static void loadProperties() {
        applicationProps = new Properties();
        try {
            applicationProps.load(AppUtils.class.getClassLoader().getResourceAsStream(
                    APP_PROP_FILE));
        }
        catch (IOException e) {
            e.printStackTrace();
        }
    }
