Issue with Persisting Blob to Database

[programmermattsrum]

So, I am able to persist to the database the Blob, BUT when it trys to resume execution on the flow I get a big fat fileNotFound Exception. Any help would be appreciated.

Thanks,

Matt

UserService.java

Images images = new Images();
		  
		  try {
			  images.setContent(Hibernate.createBlob(user.getFile().getBytes()));
		  } catch (IOException e) {}
		  
		  images.setName(user.getFile().getOriginalFilename());
		  images.setSize(new Long(user.getFile().getSize()).intValue());
		  images.setType(user.getFile().getContentType());
		  user.getPerson().setImages(images);
		  personDao.save(user.getPerson());

jsp fragment

 <label class="float-left" for="person.images"><spring:message code="profilePhoto" /></label>
	        <span class="float-right"><form:input type="file" class="text ui-widget-content ui-corner-all" path="file" /> </span>
	        <br class="clear-float"/>

I really need an answer or some lead on what to do to fix this. Any ideas Keith?

So I finally found a post that has my problem. It is solved in post - http://forum.springsource.org/showthread.php?t=54466. Basically i just set the bean that is the multipartfile to null after saving to the database and then there is no error anymore.
