Guys,
I am able to convert FormFile into byutes using getFileData();
But when I am tryint oconvert into BLOB,it is dhoowing me the error.
Please find the complete details below.
I am trying to Upload one file using FormFile of Struts and I need to pass that Form File into one procedure having BLOB as aIn parameter. SO I need to convert that file into BLOB object
The code that I am trying is :
try{
BLOB blob= BLOB.getEmptyBLOB();
System.out.println("before");
blob.setBytes(theFile.getFileData());
System.out.println("after");
cs.setBlob(3, blob);
}catch(Exception e){System.out.println("in the BLOB "+e);}
After running the code,I am getting the following error
