Class JasperMultipleReportBaseAction

java.lang.Object

org.openxava.actions.BaseAction

org.openxava.actions.ViewBaseAction

org.openxava.actions.JasperMultipleReportBaseAction

All Implemented Interfaces:

IAction, IChangeModeAction, IModelAction, IModuleContextAction, IMultipleForwardAction, IRequestAction

Direct Known Subclasses:

JasperConcatReportBaseAction

public abstract class JasperMultipleReportBaseAction
extends ViewBaseAction
implements IMultipleForwardAction, IModelAction

To generate several custom Jasper Reports with the same action.

You only need to overwrite the abstract methods.
To send parameters to the reports you have 3 options.

1. If all the repors use the same parameters just overwrite getParameters().
2. If each report has different parameter overwrite getParameters(int i), or well
3. overwrite execute() and before calling to super.execute() call to addParameters() method.

Option 1 for parameters

public Map getParameters() throws Exception { Map parameters = new HashMap(); parameters.put("param1", value1); parameters.put("param2", value2); return parameters; }

Option 2 for parameters

protected Map getParameters(int index) throws Exception { Map parameters = new HashMap(); switch (index) { case 0: parameters.put("param1", value1); parameters.put("param2", value2); return parameters; case 1: parameters.put("param3", value3); parameters.put("param4", value4); return parameters; } return null; }

Option 3 for parameters

public void execute() throws Exception { Map parameters1 = new HashMap(); parameters1.put("param1", value1); parameters1.put("param2", value2); addParameters(parameters1); Map parameters2 = new HashMap(); parameters1.put("param3", value3); parameters1.put("param4", value4); addParameters(parameters2); super.execute(); }

Method Detail

getDataSources

protected abstract net.sf.jasperreports.engine.JRDataSource[] getDataSources()
                                                                      throws java.lang.Exception

Data to print.

If return null then a JDBC connection is sent to JasperReport, this is for the case of a SQL inside JasperReport design.

Throws:

java.lang.Exception

getJRXMLs

protected abstract java.lang.String[] getJRXMLs()
                                         throws java.lang.Exception

The name of the XML with the JasperReports design.

If it is a relative path (as reports/myreport.jrxml has to be in classpath. If it is a absolute path (as /home/java/reports/myreport.xml or C:\\JAVA\\REPORTS\MYREPORT.JRXML then it look at the file system.

Throws:

java.lang.Exception

getParameters

protected java.util.Map getParameters()
                               throws java.lang.Exception

Parameters to send to report.

Throws:

java.lang.Exception

getParameters

protected java.util.Map getParameters(int i)
                               throws java.lang.Exception

Retrieve parameters for the specified report index.

Maintains backward compatibility by calling getParameters() if parameters list is empty or not enough parameter sets defined.

Throws:

java.lang.Exception

Since:

4.5

getFormat

public java.lang.String getFormat()
                           throws java.lang.Exception

Output report format, it can be 'pdf' or 'excel'.

Throws:

java.lang.Exception

setFormat

public void setFormat(java.lang.String format)
               throws java.lang.Exception

Output report format, it can be 'pdf', 'excel' or 'rtf'.

Throws:

java.lang.Exception

Throws:

java.lang.Exception

getForwardURIs

public java.lang.String[] getForwardURIs()

Description copied from interface: IMultipleForwardAction

The URIs to go.

If it starts with "http://" or "http://" the action will forward to the absolute URL in internet, if it starts with "javascript:" the corresponding code will executed by the browser, otherwise it will forward to a resource inside this application.

Specified by:

getForwardURIs in interface IMultipleForwardAction

inNewWindow

public boolean inNewWindow()

Set parameter list.

Allows setting the parameter list outside this code.

Since:

4.5

getParametersList

public java.util.List<java.util.Map> getParametersList()
