What would be the return type of java action to convert a file/document to BLOB
I am trying to convert file/document to BLOB. I have created a custom java action but facing issue with the code which otherwise works in a backend service. Blob attachment = null; byte data = Files.readAllBytes(this.BulkUploadFile); attachment = new SerialBlob(data); return attachment;
You can't return SerialBlob in a Mendix Java Action. If you need the blob contents in a microflow, you should convert the blob to a string and return the string.
