Interface AsyncRequestDispatcherConfig


public interface AsyncRequestDispatcherConfig
AsyncRequestDispatcherConfig is used to pass custom config for a particular request dispatcher including error messages, timeouts, etc. If various encodings are not specified, the default encoding value of the top level response's getCharacterEncoding() method is used.

      Returns:
      encoding
    • setExecutionTimeoutOverride

      void setExecutionTimeoutOverride(int ms)
      Set the maximum length of time allowed for the execution of an include. Does not apply to insertFragmentBlocking calls.

    • getExecutionTimeoutMessage

      String getExecutionTimeoutMessage()
      Return the message displayed if the maximum length of time for the execution of an include is reached. The default value is 60000 ms (or one minute). If this execution timeout is reached, but the actual include results are ready once the data can be flushed, preference is given to the actual results to be sent.
      Returns:

      true/false
    • setRetriable

      void setRetriable(boolean retriable)
      Set whether or not we will retry the include if we've received a rejected work item.
      Parameters:
      retriable -
    • isTransferState

      boolean isTransferState()
      This must be set if the developer needs request attributes and internal headers returned to the top level request. This only works for insertFragmentBlocking since that is the only insertion method that guarantees the top level request still exists.
      Returns:
      true/false
    • setTransferState

      void setTransferState(boolean state)
      Set the value of transfer state.
      Parameters:
      state -
    • isUseDefaultJavascript

      boolean isUseDefaultJavascript()
      Returns true when ARD sends the javascript to aggregate the content on the client side. Returns false when the customer must implement their own code to aggregate content on the client side. They should retrieve the request attribute "com.ibm.websphere.webcontainer.ard.endpointURI" to get this endpoint and then make XMLHttpRequests to retrieve the results
      Returns:
      true/false
    • setUseDefaultJavascript

      void setUseDefaultJavascript(boolean useDefaultJavascript)
      sets whether to allow ARD to insert javascript into customer code to retrieve results for client-side aggregation.
      Parameters:
      useDefaultJavascript -
    • addThreadLocalToPropagate

      void addThreadLocalToPropagate(ThreadLocal threadLocals)
      Since the AsynchBeans executes the includes on a non-child thread, InheritableThreadLocals will not work so a mechanism is provided to propagate them
      Parameters:
      threadLocals -
    • getThreadLocalsToPropagate

      List<ThreadLocal> getThreadLocalsToPropagate()
      Since the AsynchBeans executes the includes on a non-child thread, InheritableThreadLocals will not work. This method allows the retrieval of the current set that need to be propagated.
      Parameters:
      a - list of ThreadLocals
    • initThreadLocals

      void initThreadLocals()
      Since the AsynchBeans executes the includes on a non-child thread, InheritableThreadLocals will not work. This method clears the list of ThreadLocals to propagate if any were set on a previous request.
