I haven't tried with the latest CVS version of Seam. But i got it working with
Seam-beta2 and Jboss-4.0.4-RC1. Here's what I did:
1. You need 2 Seam components. A "backing bean" required by Tomahawk and SLSB
to deal with your JSF action:
1a. Backing Bean:
| @Name("uploadBean")
| public class UploadBackingBean {
|
| private UploadedFile file;
|
| public void setFile(UploadedFile file) {
| this.file = file;
| }
|
| @NotNull
| public UploadedFile getFile() {
| return this.file;
| }
|
| }
|
1b. Action and its interface
| @Stateless
| @Name("upload")
| @Interceptors(SeamInterceptor.class)
| public class UploadAction implements Upload {
|
| private Logger logger;
|
| /**
| * O arquivo que foi enviado.
| */
| @In
| private UploadBackingBean uploadBean;
|
| @In
| private FacesContext facesContext;
|
| @PostConstruct
| public void init() {
| logger = Logger.getLogger(this.getClass());
| logger.debug("init()");
| }
|
| public String upload() {
| logger.debug("upload()");
| UploadedFile file = uploadBean.getFile();
|
| logger.debug("Abrindo o arquivo como DOM4J");
|
| logger.debug(file.getName());
|
| facesContext.addMessage(null, new FacesMessage("Nome do arquivo: "
| + file.getName()));
|
| return "success";
| }
|
| }
|
| @Local
| public interface Upload {
|
| public String upload();
|
| }
|
2. You need to define a tomahawk.taglib.xml if you want to be able to access
your tomahawk upload component via facelets. It shoud go in your .war WEB-INF
| <?xml version="1.0"?>
| <!DOCTYPE facelet-taglib PUBLIC "-//Sun Microsystems, Inc.//DTD Facelet
Taglib 1.0//EN" "facelet-taglib_1_0.dtd">
| <facelet-taglib>
| <!-- author: [EMAIL PROTECTED] -->
| <namespace>http://myfaces.apache.org/tomahawk</namespace>
| <tag>
| <tag-name>inputFileUpload</tag-name>
| <component>
|
<component-type>org.apache.myfaces.HtmlInputFileUpload</component-type>
| </component>
| </tag>
| </facelet-taglib>
|
A full taglib definition is available here:
http://wiki.apache.org/myfaces-data/attachments/Use_Facelets_with_Tomahawk/attachments/tomahawk.taglib.xml
3. Apart from the normal Seam stuff in your web.xml you need to reference
whatever is that Tomahawk needs:
| <!-- My Faces Extensions Filter -->
| <filter>
| <filter-name>extensionsFilter</filter-name>
|
<filter-class>org.apache.myfaces.component.html.util.ExtensionsFilter</filter-class>
| <init-param>
| <param-name>uploadMaxFileSize</param-name>
| <param-value>100m</param-value>
| <!--
| <description>Set the size limit for uploaded files.
| Format: 10 - 10 bytes
| 10k - 10 KB
| 10m - 10 MB
| 1g - 1 GB
| </description>
| -->
| </init-param>
| <init-param>
| <param-name>uploadThresholdSize</param-name>
| <param-value>100k</param-value>
| <!--
| <description>Set the threshold size - files
| below this limit are stored in memory, files above
| this limit are stored on disk.
|
| Format: 10 - 10 bytes
| 10k - 10 KB
| 10m - 10 MB
| 1g - 1 GB
| </description>
| -->
| </init-param>
| <!--
| <init-param>
| <param-name>uploadRepositoryPath</param-name>
| <param-value>/temp</param-value>
| <description>Set the path where the intermediary files will be
stored.
| </description>
| </init-param>
| -->
| </filter>
|
| <filter-mapping>
| <filter-name>extensionsFilter</filter-name>
| <url-pattern>*.seam</url-pattern>
| </filter-mapping>
|
| <!-- MyFaces Tomahawk Library -->
|
| <context-param>
| <param-name>facelets.LIBRARIES</param-name>
| <param-value>/WEB-INF/tomahawk.taglib.xml</param-value>
| </context-param>
|
4. The HTML would look something like this:
| <h:form enctype="multipart/form-data">
| <t:inputFileUpload storage="file" value="#{uploadBean.file}"/>
| <h:commandButton value="Submit" action="#{upload.upload}"/>
| <h:messages/>
| </h:form>
|
5. Finally I put the tomahawk.jar and the commons-file-upload.jar and
common-io.jar in the .ear that packages the web application and the EJB's. Of
course you need to add the class-path in the MANIFEST.MF of the .ear file.
| Class-Path: jboss-seam.jar commons-fileupload-1.1.jar commons-io-1.2.jar
tomahawk.jar
|
Hope it helps.
Regards.
