When iam tring to insert a pdf of 2mb in to oracle database.This is my source code.import java.io.File;import java.io.FileInputStream;import java.sql.Connection;import java.sql.DriverManager;import java.sql.PreparedStatement;public class PDFConnect { public static void main(String args[]) { try{ Class.forName("oracle.jdbc.driver.OracleDriver"); Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@10.81.7.169:1521:PTS", "TESTPTS", "TESTPTS"); System.out.println("connection established"); PreparedStatement ps = conn.prepareStatement("insert into DEMOBLOB values(?)"); System.out.println("insert executed"); File photo= new File("D:/Thinkingjava.pdf"); System.out.println("image loaded "); FileInputStream photostream= new FileInputStream(photo); System.out.println("photo taken"); ps.setBinaryStream(1,photostream,(int)photo.length()); ps.executeUpdate(); photostream.close(); } catch(Exception e) { e.printStackTrace(); } } }above is the code which iam using and below is the exception i am gettingORA-01460: unimplemented or unreasonable conversion requested at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:114) at oracle.jdbc.ttc7.TTIoer.processError(TTIoer.java:208) at oracle.jdbc.ttc7.Oall7.receive(Oall7.java:542) at oracle.jdbc.ttc7.TTC7Protocol.doOall7(TTC7Protocol.java:1311) at oracle.jdbc.ttc7.TTC7Protocol.parseExecuteFetch(TTC7Protocol.java:738) at oracle.jdbc.driver.OracleStatement.executeNonQuery(OracleStatement.java:1313) at oracle.jdbc.driver.OracleStatement.doExecuteOther(OracleStatement.java:1232) at oracle.jdbc.driver.OracleStatement.doExecuteWithBatch(OracleStatement.java:1353) at oracle.jdbc.driver.OracleStatement.doExecute(OracleStatement.java:1760) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1807) at oracle.jdbc.driver.OraclePreparedStatement.executeUpdate(OraclePreparedStatement.java:332) at PDFConnect.main(PDFConnect.java:24)
