Hi there,

I have a Java Stored Procedure in Oracle that converts a CLOB feed of SVG based XML into a PDF file and stores it as a BFILE.

The following code works.

Code:

CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED DMG."com/aca/pdfwriter" AS

package com.aca.pdfwriter;

//import Java

import java.io.BufferedReader;

import java.io.File;

import java.io.IOException;

import java.io.OutputStream;

import java.io.BufferedReader;

import java.io.InputStream;

import java.io.InputStreamReader;

import java.sql.PreparedStatement;

import java.sql.Blob;

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.ResultSet;

import java.sql.SQLException;

import java.sql.Statement;

//import oracle

import oracle.jdbc.pool.OracleDataSource;

import oracle.jdbc.OracleResultSet;

import oracle.sql.BFILE;

import oracle.sql.BLOB;

import oracle.sql.CLOB;

//import Batik

import org.apache.batik.transcoder.Transcoder;

import org.apache.batik.transcoder.TranscoderException;

import org.apache.batik.transcoder.TranscoderInput;

import org.apache.batik.transcoder.TranscoderOutput;

import org.apache.batik.gvt.font.GVTGlyphVector;

import org.apache.avalon.framework.configuration.Configuration;

import org.apache.avalon.framework.configuration.DefaultConfigurationBuilder;

import org.apache.fop.svg.PDFTranscoder;

import org.apache.fop.fonts.apps.PFMReader;

public class svg2pdf{

public static int convertSVG2PDF(oracle.sql.CLOB svg) throws IOException, TranscoderException,SQLException {

InputStream in = null;

int seq =0;

Transcoder transcoder = new org.apache.fop.svg.PDFTranscoder();

//Setup input

//InputStream in = new java.io.FileInputStream(svg);

//svg.open();

//in = svg.getBinaryStream();

in = svg.getAsciiStream();

try {

TranscoderInput input = new TranscoderInput(in);

//get the current connection

Connection conn = DriverManager.getConnection("jdbc:default:connection");

conn.setAutoCommit(false); //must be set to false

//Get unique sequence number

Statement stmt = conn.createStatement();

ResultSet rset = stmt.executeQuery("select TEMP_BLOB_SEQ.nextval from dual");

while (rset.next()) {

seq = ((OracleResultSet)rset).getInt(1);

}

stmt.close();

//Prepare the new blob

PreparedStatement pstmt = conn.prepareStatement("insert into temp_blob (unique_id,blobby) values (" + seq + ", ?)");

oracle.sql.BLOB myBlob = oracle.sql.BLOB.createTemporary(conn, true, oracle.sql.BLOB.DURATION_SESSION);

//Setup the outputstream

OutputStream out = null;

out = myBlob.setBinaryStream(0);

try {

System.out.println("start PDF" );

TranscoderOutput output = new TranscoderOutput(out);

//Do the transformation

transcoder.transcode(input, output);

System.out.println("Generated PDF" );

pstmt.setBlob(1,myBlob);

pstmt.execute();

pstmt.close();

} catch (Exception e){

System.out.println(e.getMessage() );

e.printStackTrace();

PreparedStatement xxx = conn.prepareStatement("insert into z (z) values (" + e.getMessage() + ")");

xxx.execute();

xxx.close();

} finally {

out.close();

conn.commit();

conn.close();

}

} finally {

in.close();

//svg.closeFile();

}

return seq;

}

**********************************

If I use the following code as my input CLOB the source is successfully transformed to PDF output.

However, if I change the hi-lighted bit to output the character 4 or x it throws an error:

*********************

I am quite baffled as to how I resolve this.

I tried naming standard fonts e.g. Courier, Arial Times Helvitica. But it came down to the same issue each time, it is only when the character 4 or x is displayed as text that the error occurs.

Any ideas would be appreciated.
