BI Publisher API Example – Creating PDF Report from XML/RTF?











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 a PDF output from XML file using the standard Oracle BI Publisher API’s (Java based).

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

Oracle have 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.

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 convertxmltopdf {

  public static void main(String[] args)
  {
    try
    {    
      FOProcessor processor = new FOProcessor();
      processor.setData(args[0]); //input XML
      processor.setTemplate(args[1]);  //input XSL template
      processor.setOutput(args[2]); // output PDF File
     
          // Set output format (for PDF generation)
      processor.setOutputFormat(FOProcessor.FORMAT_PDF);
      // Start processing
   
      processor.generate();
    }
    catch (Exception e)
    {
       e.printStackTrace();
       System.exit(1);
    }

    System.exit(0);
   
  }
}

STEP3: Compile the Java wrapper

javac -classpath $CLASSPATH convertxmltopdf.java

Step 4: Copy the Wrapper Class to JAVA_TOP

cp convertxmltopdf.class $JAVA_TOP

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

Input XML:
clip_image001[6]
Actual RTF:
clip_image003[6]
Generated XSL-FO based on Step 1:
clip_image005[6]

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

java -classpath $CLASSPATH convertxmltopdf ./INPUTDATAXML.xml ./RTFTEMPLATEEX.xsl ./RTFTEMPLATEEX.pdf
clip_image007[6]

Output PDF:
clip_image009[6]

Hi Team,
Do we have a way to we can call the XML report which is attached in data definition via API. I understand this example is placing the data definition and RTF template at the particular direcotry and processing the output. But i like to know is there a way where we can use the data definition which is attached in the XML administrator respondibility data defintion screen. Thanks in advance.
