Call Oracle Reports From Your ADF Application

One of the main issues that can face oracle ADF Developers is calling oracle reports.
This post will illustrate step by step how to call oracle reports.

1- Create new ADF Application and make new .jspx page (this page will be a parameter page which will send the parameters to the report).

2- Insert inside page inputTexts which will hold the parameters and insert one commandButton which will run the report.



3- Bind the command button to the method in backbean and write this code:
OracleReportBean reportBean =
new OracleReportBean("oracleServerId", "Port", null);
reportBean.setReportServerParam(OracleReportBean.RS_PARAM_DESTYPE,"DisplayType");// which will be one of the [cashe - file - mail - printer]
reportBean.setReportServerParam(OracleReportBean.RS_PARAM_DESFORMAT,"Format"); // Which will be onr of the [HTML - HTML CSS - PDF - SPREADSHEET- RTF].
reportBean.setReportParameter(parameterName1, parameterValue1);// as report name
reportBean.setReportParameter(parameterName2, parameterValue2);
reportBean.setReportParameter(parameterName3, parameterValue3);
String url = reportBean.getReportServerURL();
reportBean.openUrlInNewWindow(url);
as in picture

4- Make a new java file which will be OracleReportBean (assume its name will be OracleReportBean.java) and write this code inside OracleReportBean.java:

import java.util.HashMap;
import java.util.Iterator;

import javax.faces.context.FacesContext;

import org.apache.myfaces.trinidad.render.ExtendedRenderKitService;
import org.apache.myfaces.trinidad.util.Service;

* This bean performs the following functions:
* Constructing the Report URL with various parameters passed in by client.
* Sending the report request.
* Execute printed report and retrieve return status in the indicated format.
* Execute a binary report (PDF, RTF, XML, with DESTYPE CACHE) and return the
* InputStream for processing.

Oracle Report URL should be at this format
http://myServer:myport/reports/rwservlet?destype=cache&desformat=PDF&report=myreport.jsp&myparameter=myvalue

5- Save and Run the application.
