## Class JasperReportsResult

- java.lang.Object
- - org.apache.struts2.result.StrutsResultSupport
  - - org.apache.struts2.views.jasperreports.JasperReportsResult

- All Implemented Interfaces:
    Result, Serializable, StrutsStatics, JasperReportConstants

      public class JasperReportsResult
      extends StrutsResultSupport
      implements JasperReportConstants

  Generates a JasperReports report using the specified format or PDF if no format is specified.

  This result type takes the following parameters:

  - location (default) - the location where the compiled jasper report definition is (foo.jasper), relative from current URL.
  - dataSource (required) - the EL expression used to retrieve the datasource from the value stack (usually a List).
  - parse - true by default. If set to false, the location param will not be parsed for EL expressions.
  - format - the format in which the report should be generated. Valid values can be found in `JasperReportConstants`. If no format is specified, PDF will be used.
  - contentDisposition - disposition (defaults to "inline", values are typically filename="document.pdf").
  - documentName - name of the document (will generate the http header `Content-disposition = X; filename=X.[format]`).
  - delimiter - the delimiter used when generating CSV reports. By default, the character used is ",".
  - imageServletUrl - name of the url that, when prefixed with the context page, can return report images.
  - reportParameters - (2.1.2+) OGNL expression used to retrieve a map of report parameters from the value stack. The parameters may be accessed in the report via the usual JR mechanism and might include data not part of the dataSource, such as the user name of the report creator, etc.
  - exportParameters - (2.1.2+) OGNL expression used to retrieve a map of JR exporter parameters from the value stack. The export parameters are used to customize the JR export. For example, a PDF export might enable encryption and set the user password to a string known to the report creator.
  - connection - (2.1.7+) JDBC Connection which can be passed to the report instead of dataSource
  - wrapField - (2.3.18+) defines if fields should warp with ValueStackDataSource see https://issues.apache.org/jira/browse/WW-3698 for more details

  This result follows the same rules from `StrutsResultSupport`. Specifically, all parameters will be parsed if the "parse" parameter is not set to false.

  Example:

       <result name="success" type="jasper">
         <param name="location">foo.jasper</param>
         <param name="dataSource">mySource</param>
         <param name="format">CSV</param>
       </result>

  or for pdf

       <result name="success" type="jasper">
         <param name="location">foo.jasper</param>
         <param name="dataSource">mySource</param>
       </result>
