Hi,
I am using Upload to uplaod an image into a streamresource and tried to create output image as document suggests:
Element avatar = new Element( "object" );
avatar.setAttribute( "type" , memoryBuffer.getFileData().getMimeType() );
avatar.getStyle().set( "display" , "block" );
avatar.setAttribute( "data" , new StreamResource( memoryBuffer.getFileName() ,
() -> new ByteArrayInputStream( userImage ) ) );
thumbnail.getElement().removeAllChildren();
thumbnail.getElement().appendChild( avatar );
However, errors popped up like:
java.io.IOException: UT010015: Could not delete file C:\Users\Joey\AppData\Local\Temp\undertow4514037988779775402upload
