Hi Eva,

This article was written quite a long time ago, for ADF 10g. In 11g, there is built-in support for export to excel, using the the panelCollection component and the af:exportCollectionActionListener component.

See for an example Exporting table to Excel in Oracle ADF

Hi Lucas, Great Job!!!
Only a small problem: when you click the export buttom on the popup window, the excel file is downloaded, but this buttom is left waiting, disabled, and does not respond. It is necessary to reload de popup for the button to display correctly again.
Â¿Any solution?Â¿Any idea?

Thanks you,
Eva

Note: I am working with JDeveloper 11.1.1.5.0

Enlightening! I particularly like the way you initialize your variables for the page with the command button action method and then return the action. Something I’ve not considered before. Great stuff!

Hi,

I just wanted to know whether it is possible to use it with JHeadstart as well as in ADF JDeveloper or not ?

Thank you,
Ahmed

Hi Lucas, Great job. we are using this in our project. While compiling ExcelExport.Java in JDeveloper 10.1.3.3.0, I am getting following errors:

HSSFCell not found
HSSFCellStyle not found
HSSFDataFormat not found
HSSFFont not found
HSSFRow not found
HSSFSheet not found
HSSFWorkbook not found
HSSFColor not found

Not able to compile the following:
import org.apache.poi.hssf.usermodel.HSSFCell;
import org.apache.poi.hssf.usermodel.HSSFCellStyle;
import org.apache.poi.hssf.usermodel.HSSFDataFormat;
import org.apache.poi.hssf.usermodel.HSSFFont;
import org.apache.poi.hssf.usermodel.HSSFRow;
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
import org.apache.poi.hssf.util.HSSFColor;

I put poi-2.5.1-final-20040804.jar in the WEB-INF/lib and also placed this poi jar file in JDev15/jdk/jre/lib directory. Am I missing something here.
I appreciate a quick response.

Thanks a lot.
Ram

Hi, used you’re code and works nice.
I made a popup dialog where the user can choose from witch table the want the make an export. After choosing the ExcelPopup.jsp is loaded.

Then I get a null pointer exception:
Caused by: java.lang.NullPointerException at apro.view.backing.global.ExcelPopup.exportThisTableToExcel(ExcelPopup.java:69)
Caused by: javax.faces.el.EvaluationException: java.lang.NullPointerException at com.sun.faces.el.MethodBindingImpl.invoke(MethodBindingImpl.java:150) at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:92)

This is the code of row 68&69:
DCBindingContainer bc = getBindingContainer();
containerName = bc.getName();

Could you please tell me what goes wrong and how I can fix it?
