Question

Hi:
I have a question about the bar code report in printer server, i can do the bar code report in my local computer ,
but it can't be work when put it into the printer server ,
It would be get the error message :
REP-110: can't open the file 'null'.
REP-1070: it have a error when it open or sqve the document.
REP-0110: can't open the file 'null'.
I had study the document orbr_barcode.pdf before,
and I do something below:
1. copy a new oraclebarcode.jar into my computer.
2. change the regedit HKEY_LOCAL_MACHINE\SOFTWARE\ORACLEHOME1\REPORTS_CLASSPATH,
add a new path that the oraclebarcode.jar was.
3. import java class
oracle.apps.barcode.util.BarCodeConstant
oracle.apps.barcode.BarCodeMaker
4. new PACKAGE globals IS
bcobj ora_java.jobject;
barcode_to_use varchar(256);
tempdir varchar(100);
directory_sep varchar(2);
END;
5.modify function BeforeReport return boolean is
begin
globals.barcode_to_use := BarCodeConstants.BAR_CODE_39;
globals.bcobj := barcodemaker.new();
return (TRUE);
end;
6. new Formula in the DataModel, and set to image,
function CF_barCodeFormula return VARCHAR2 is
myfilename varchar2(500);
result varchar2(500);
barcodeData VarChar2(500) := :ast_no;
begin
myFileName := srw.create_temporary_filename;
barcodemaker.setBarWidthInch(globals.bcobj,0.005);
barcodemaker.setBaseCodeData(globals.bcobj,barcodeData);
barcodemaker.setBarCodeType(globals.bcobj,globals.barcode_to_use);
myFileName := barcodeData;
barcodemaker.setFullPath(globals.bcobj, myFileName);
barcodemaker.renderBarCode(globals.bcobj);
return(myfilename);
end;
It's success when I build a bar code report in local computer,
but I copy the oraclebarcode.jar into printer server and chage the HKEY_LOCAL_MACHINE\SOFTWARE\ORACLEHOME1\REPORTS_CLASSPATH, but it get the error message ...
