Usage

From source file:org.jbpm.bpel.tutorial.invoice.ComputePricePT_Impl.java

protected void sendInvoiceMessage(float shippingPrice) throws JMSException {
    ServletContext servletContext = endpointContext.getServletContext();
    Integer orderId = (Integer) servletContext.getAttribute(ORDER_ID_ATTR);
    Float linePrice = (Float) servletContext.getAttribute(LINE_PRICE_ATTR);

    // create a session
