Seam 1.2.1GA
Jboss 4.0.5
I think the challenge here is not receiving the file, but then being able to
write the file to a specified location.
Specifically, I wish to allow a user to upload a .jpg or .png and have it saved
off my webroot so that the image can be displayed using an image tag. I do not
want to save these images into the database as seamspace and ui does. I want
to put them into the filesystem.
I currently have s:fileupload configured and working. The filecontents are
available to my SFSB as
| private byte[] picture
|
Even if it was an InputStream, I still need to be able to write it out to a new
file off of webroot.
Here is what I have so far:
profile.xhtml
| <s:fragment rendered="#{user.picture ne null}">
| <s:div id="memberPicture">
| <h:outputLabel for="picture">Member
photo:</h:outputLabel>
| <h:outputText
value="#{user.picture.originalFilename}" />
| <h:graphicImage
value="/content/#{user.picture.filename}"/>
| </s:div>
| </s:fragment>
| <s:fragment rendered="#{identity.loggedIn and
(loggedInUser.id==user.id)}">
| <s:fragment rendered="#{user.picture==null}">
| <h:form enctype="multipart/form-data">
| <s:validateAll>
| <div class="formRow">
| <h:outputLabel
for="picture">Member photo</h:outputLabel>
| <s:fileUpload id="picture"
data="#{profile.picture}" accept="images/png,images/jpg"
contentType="#{profile.pictureContentType}"
fileName="#{profile.pictureOriginalFilename}"/>
| <div
class="validationError"><h:message for="picture"/></div>
| </div>
| </s:validateAll>
| <div class="buttons">
| <h:commandButton value="Upload"
action="#{profile.addPicture}" />
| </div>
| </h:form>
| </s:fragment>
| <s:fragment rendered="#{user.picture ne null}">
| <h:form enctype="multipart/form-data">
| <div class="buttons">
| <h:commandButton value="Delete"
action="#{profile.deletePicture}" />
| </div>
| </h:form>
| </s:fragment>
| </s:fragment>
|
ProfileAction.java (the SFSB)
| @Stateful
| @Name("profile")
| public class ProfileAction implements Profile
| {
| @In(required = false, create = false)
| @Out(required = false, scope=SESSION)
| private User loggedInUser;
|
| private String pictureOriginalFilename;
| private String pictureContentType;
| private byte[] picture;
| ...
|
| public String addPicture()
| {
| log.info("addPicture() called");
| log.info("addPicture() - picture size in bytes:#0",
picture==null?"0":picture.length);
| log.info("addPicture() - original filename:#0",
pictureOriginalFilename);
| log.info("addPicture() - contentType:#0",
pictureContentType);
|
| User userToUpdate = em.find(User.class,
loggedInUser.getId());
| if (picture != null && picture.length > 0)
| {
| log.info("addPicture() - about to save MemberImage");
|
| // need to save byte[] picture to a unique filename
| try
| {
| OutputStream pictureFileStream = new
FileOutputStream(pictureOriginalFilename);
| pictureFileStream.write(picture);
| pictureFileStream.close();
| } catch (Exception e)
| {
| log.info("addPicture() - Problem saving picture: #0", e);
| }
| MemberImage img = new MemberImage();
| img.setMember(userToUpdate);
| img.setContentType(pictureContentType);
| img.setOriginalFilename(pictureOriginalFilename);
| img.setFilename(pictureOriginalFilename);
| em.persist(img);
| log.info("addPicture() - saved MemberImage:#0", img);
|
| userToUpdate.setPicture(img);
| em.persist(userToUpdate);
|
| loggedInUser = userToUpdate;
| }
|
| return "success";
| }
|
| ...
|
| }
|
How do I write the file out to my webroot? Specifically, I want to write them
into /content and be able to use s:graphicImage to display it. Any code
examples would be very much appreciated.
