Hi dear All.

1. I load JXL package to database using
loadjava -v -r user_name/pass@sid -r jxl.jar


2. I have created stored procedure in oracle as follows:
create or replace and compile java source named createReport as

import jxl.Workbook;
import jxl.write.Label;
import jxl.write.WritableSheet;
import jxl.write.WritableWorkbook;
import java.io.File;

public class createReport {
  private static String filePath;
  private static String fileName;

//for excel writing  
  private static WritableSheet sheet;
  private static Label label;
  private static WritableWorkbook workbook;  
  
  
  private static String runReportByRows() {
    try{
      int fileIndex = 0;
      workbook = Workbook.createWorkbook(new File(filePath+fileName+"_"+fileIndex+".xls"));
      sheet = workbook.createSheet("Sheet"+fileIndex, 0);

      label = new Label(1, 1 ,"TEST");
      sheet.addCell(label);

      workbook.write();
      workbook.close();
      return "OK";
    } catch (Exception e){
      return "Error: "+ e.toString();
    } 
  }
  
  public static String createReport(String filePath1,String fileName1){
    filePath = filePath1;
    fileName = fileName1;

    String selectStatement = "";
    try {
      String returnedString = runReportByRows();  
      return returnedString;
    } catch (Exception e) {
      return "Error: "+ e.toString();
    }
  }
}
/

create or replace function Func_createReport(filePath String, fileName String) return varchar2
is language java name
'createReport.createReport(java.lang.String,java.lang.String) return java.lang.String';
/


3. I have granted permissions to my user from sys account to folder in which i want to create file:
BEGIN
  DBMS_JAVA.GRANT_PERMISSION ( 'user_name', 'java.io.FilePermission','C:\temp\', 'read,write' );
  COMMIT;
END;
/


4. I call procedure:
declare
  str varchar2(1000);
begin
  str := odb.func_createReport('c:/temp/','test');
  dbms_output.put_line(str);
end;


I get following error:
Quote:
call was terminated by uncaught Java exception: java.lang.AbstractMethodError: Error detected by bytecode verifier when class was created


I create additional table and insert rows to that table from different places in code and i see that the error happens on
workbook.write();
statement.

Someone can help me?

I will not say that this is urgent. Razz

Hello Again.

Thanks for answers. Laughing

All the problem is in the JXL package, which use the latest version of jdk that Oracle 9iR2 got. I test same package on Oracle10g and it works great.

Thanks for everyone. If someone can slove that problem on Oracle9iR2 please tell me to.
