File upload error

[jegadeeshsp]

Dear all,

I'm trying to upload a file to database, i uploaded a image size is lessthan 4 kb using blb,
when I try with a image or file morethan 4kb, i'm getting an error:
ORA-01460: unimplemented or unreasonable conversion requested

i added my java code below,
package Action;

import java.io.FileInputStream;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Blob;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;
import org.apache.struts.upload.MultipartRequestHandler;

import Form.StrutsUploadForm;

/**
* @author jegadeeswaran
*
*/
public class StrutsUploadAction extends Action {

Connection conn = null;
ResultSet rset = null;
int s=0;

public ActionForward execute
(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception{

StrutsUploadForm myForm = (StrutsUploadForm)form;
FormFile myFile = myForm.getTheFile();
String contentType = myFile.getContentType();
System.out.println(">> contentType: >> " +contentType);
String fileName = myFile.getFileName();
System.out.println(">> File Name: >> " +fileName);
int fileSize = myFile.getFileSize();
System.out.println(">> File Size: >> " +fileSize);
byte[] fileData = myFile.getFileData();
System.out.println(">> file data: >> " +fileData);
InputStream inFile = myFile.getInputStream();
Class.forName("oracle.jdbc.driver.OracleDriver");
conn =DriverManager.getConnection("jdbc:oracle:thin:@de vdbserver.edkaladc.com:1521:EDKADCDB","jegadeeswar an","jeg");
System.out.println("connection >> "+conn);
PreparedStatement pstmt = conn.prepareStatement("insert into ABSFILEUPLOAD (filename,upfile) values(?,?)");
// conn.prepareCall("{call package.functionname(?,?)}");
System.out.println("prepared statement >> "+pstmt);
pstmt.setString(1,fileName);
pstmt.setBinaryStream(2,inFile,fileSize);
s = pstmt.executeUpdate();
System.out.println("quert execute resultset >> "+s);
pstmt.close();
System.out.println("Insertion successfull");
return mapping.findForward("success");
}
}

note:
1.i have given the buffer size in the controller
2.i added ojdbc jar also

Is that a Database error message? It doesn't look like a java error message.

Is that a Database error message? It doesn't look like a java error message.

you may be right, but i am able upload a file or image <4kb to database.
but when the size is exceeding 4kb this ORA error coming.....

To upload more size i have given the buffer size also in struts-config.xml
<controller maxFileSize="99999k" bufferSize="99999"/>.
