    • resolveURI

      @Deprecated public static String resolveURI(jakarta.servlet.http.HttpServletRequest request, boolean includePath)
      Deprecated.
      Use resolveFullUri(HttpServletRequest) instead.
      Resolve a URI (usually a resource subject or info URI) based on the settings of org.eclipse.lyo.oslc4j.publicURI and org.eclipse.lyo.oslc4j.disableHostResolution. If the publicURI property is set, it takes precedence and is used to build the full URI. If the disableHostResolution property is false or not set, resolution of the local hostname is attempted. If the disableHostResolution property is true or resolution has failed, the hostname is retrieved from the request. Query parameters from the request are not copied to the resolved URI.
      Parameters:
      request - - request to base resolved URI on
      includePath - - if the path (after the context root) should be included in the resolved URI
      Returns:
      String containing the resolved URI

    • getServletURI

      public static String getServletURI()
      Return the public URI including the servlet path. Typically, this would be something like "localhost:8080/adaptor-webapp/services", whereas the publicURI would typically be the base "localhost:8080/adaptor-webapp"
