List of evaluateExpressionGet() Examples

Examples of evaluateExpressionGet()

javax.faces.application.Application.evaluateExpressionGet()

Get a value by evaluating an expression.

Call {@link #getExpressionFactory} then call {@link ExpressionFactory#createValueExpression} passing the argumentexpression and expectedType. Call {@link FacesContext#getELContext} and pass it to {@link ValueExpression#getValue}, returning the result.

An implementation is provided that throws UnsupportedOperationException so that users that decorate the Application continue to work.

      order.setOrderDate(new Timestamp((new Date()).getTime()));
