BI Publisher API Example – Creating EXCEL Report from XML/XSL-FO/RTF in Oracle Apps?

Oracle has shared us a set of BI Publisher Java Classes for performing various BI Publisher function like converting RTF to XSL-FO, generating PDF output from XSL-FO and XML etc.
In this post, we will generate an EXCEL report output from XML file and RTF Template using the standard Oracle BI Publisher API’s (Java based).

STEP1: Prepare and Convert RTF template to XSL-FO file

Oracle has provided a Java Class to generate PDF output based on XSL-FO file and XML input. Hence, first step is to generate the XSL-FO file based on RTF template. Details are available in another article,
Now, we should be having a XSL-FO file now.

STEP2: Prepare the Java wrapper Class for calling Standard class FOProcessor

import java.io.InputStream;
import java.io.OutputStream;
import oracle.apps.xdo.template.FOProcessor;
import oracle.apps.xdo.template.fo.util.FOUtility;
import java.io.*;
import oracle.apps.xdo.common.pdf.util.PDFDocMerger;
import oracle.apps.xdo.batch.DocumentProcessor;

public class convertxmltoexcel {

  public static void main(String[] args)
      FOProcessor processor = new FOProcessor();
      processor.setData(args[0]); //input XML
      processor.setTemplate(args[1]);  //input XSL template
      processor.setOutput(args[2]); // output Excel File
          // Set output format (for EXCEL generation)
      // Start processing
    catch (Exception e)


STEP3: Compile the Java wrapper

javac -classpath $CLASSPATH convertxmltoexcel.java

Step 4: Copy the Wrapper Class to JAVA_TOP

cp convertxmltoexcel.class $JAVA_TOP

STEP5: Verify the Sample RTF template, XSL-FO file and XML File

Input XML:
Actual RTF:
Generated XSL-FO based on Step 1:

Step6: Place the XSL-FO and Input XML file in Desired Directory and Call the Wrapper Java Class

java -classpath $CLASSPATH convertxmltoexcel ./INPUTDATAXML.xml ./RTFTEMPLATEEX.xsl ./RTFTEMPLATEEX.xls

Output Excel Report:
Now the Command given in the step6 can be called from HOST based concurrent program in Oracle Apps.

Happy Shairng !! Enjoy Learning!!

even if I pass format as FOProcessor.FORMAT_EXCEL, file contains data in HTML format. Any suggestions.
