I need to store a pdf (each pdf will be < 5 pages maximum) in a mySQL database (yes I know this is not recommended). The column is defined as mediumblob. The test pdf is 198 KB. I get the error “Errors occurred in addMedicalPlan: java.io.FileNotFoundException: " followed by a dump of the file " JVBERi0xLjcKCjQgMCBvYmoKKElkZW50aXR5KQplbmRvYmoKNS …” and at the end “(The filename or extension is too long)”.
I have managed to do this with images and have been trying to re-purpose that code to store the pdf; by researching articles and other questions. Unfortunately, for me, most of the example relate to PHP. I have been able to read the pdf and display it in the page with this code:
HTML:
<div class="form-group">
<embed width="191" height="207" id="image" src="" type="application/pdf">
<input class="form-control-file col-lg-12 col-md-12 col-sm-12 col-xs-12 photo-input" type="file" id="photo" name="photo" placeholder="PDF">
</div>
jQuery:
$(document).on( 'change' , '.photo-input' , function(){
//Check for a valid image extension
var img1 = this .files[ 0 ].type;
alert( "img1: " + img1);
var mySubString = img1.substring(
img1.lastIndexOf( "image" ) + 13
);
alert( "mySubString: " + mySubString)
if ($.inArray(mySubString, [ 'pdf' ]) == - 1 ) {
alert( 'Add invalid extension 1!' );
$( '#image' ).attr( 'src' , '' );
} else {
//Check for a valid image size
if ( this .files[ 0 ].size < 10000000 ){
readURL( this , this .id);
} else {
alert( "This image is to large (must be < 1 MB)." )
$( '#image' ).attr( 'src' , '' );
}
var img1 = document.getElementById( 'image' );
img2 = (img1.getAttribute( 'src' )).replace(/^data:application\/(pdf);base64,/, "" );
}
});
function readURL(input, id) {
if (input.files && input.files[ 0 ]) {
var reader = new FileReader();
reader.onload = function (e) {
$( '#image' ).attr( 'src' , e.target.result);
}
reader.readAsDataURL(input.files[ 0 ]);
}
}
Do I need to strip off “data:application/(pdf);base64”, i.e., img2 = (img1.getAttribute(‘src’)).replace(/^data:application/(pdf);base64,/, “”); for the pdf? I do similar for storing my images (i.e., img2 = (img1.getAttribute(‘src’)).replace(/^data:image/(png|jpg|jpeg|gif);base64,/, “”);). Is this superfluous for pdf files?
I then pass the pdf to be stored with ajax:
$.ajax({
type: "POST" ,
url: "MedicalPlanAddView" ,
cache: false ,
data : {
ssAccountLevel : sessionStorage.getItem( 'ssAccountLevel' ),
ssAccountID : sessionStorage.getItem( 'ssAccountID' ),
ssNameID : sessionStorage.getItem( 'ssNameID' ),
image : img2,
mpNameAdd: $( "#mpNameAdd" ).val(),
},
})
And the server side java is:
private static byte [] getByteArrayFromFile( final String handledDocument) throws IOException {
final ByteArrayOutputStream baos = new ByteArrayOutputStream();
final InputStream in = new FileInputStream(handledDocument);
final byte [] buffer = new byte [ 500 ];
int read = - 1 ;
while ((read = in.read(buffer)) > 0 ) {
baos.write(buffer, 0 , read);
}
in.close();
return baos.toByteArray();
}
ps.setString( 1 , nameId);
ps.setString( 2 , medicalPlanName);
ByteArrayInputStream bais = new
ByteArrayInputStream(getByteArrayFromFile(medicalPlan)); //pdf image
ps.setBlob( 3 , bais);
ps.setString( 4 , updateDate);
ps.executeUpdate();
I am not a programmer and am doing this pro-bono and learning as I go for my organisation.
