Uploaded File Problem

hoetschmann Dec 8, 2005 2:15 PM

Hi!
I' m using the DVD example as template for a small application, which should download Files.

I use the tomahawk extensions:

...
<x:inputFileUpload id="myFileId"
 value="#{topic.mytmpfile}"
 storage="file"
 required="true"/>
 <h:message for="myFileId" styleClass="errors" />
 </div>
 <div class="entry">
 <div class="label"> </div>
 <div class="input">
 <h:commandButton action="#{topic.processMyFile}" value="Hochladen"/>
 </div>
 </div>
...

The managed bean (extends the EntityBean Topic) has an attribut mytmpfile and a method to process the file(persist somewhere):

public class TopicBean extends Topic implements Serializable{
 private UploadedFile mytmpfile;
...
public String processMyFile() {

 if (mytmpfile != null && tmptopic!=null) {
 //here the exception occurs!
 MyFile tmp=new MyFile(mytmpfile);
 Topic tmpTopic= Utils.getTopicEdit().getTopicByName(tmptopic);
//get the interface of the stateless session bean and addthe file
Utils.getTopicEdit().addFile(tmp,tmpTopic);
 mytmpfile=null;

 return "uploaded";
 } else {
 System.out.println("Data incomplete...");
 return null;
 }
 }

When this line(MyFile tmp=new MyFile(mytmpfile)) is executed the following Exception occurs:

java.lang.LinkageError: loader constraints violated when linking org/apache/myfaces/custom/fileupload/UploadedFile class

This is the Entity Bean MyFile:

package org.jboss.projects.performance.entities;


import static javax.persistence.GeneratorType.AUTO;

import java.io.File;
import java.io.Serializable;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;

import org.apache.myfaces.custom.fileupload.UploadedFile;
import org.hibernate.validator.Length;
import org.hibernate.validator.NotNull;

@Entity
@Table(name="files")
public class MyFile implements Serializable{

 private static final long serialVersionUID = 1L;

 private long id;
 private String name;

 private UploadedFile file;

 public MyFile()
 {

 }
 public MyFile(UploadedFile file)
 {
 this.file=file;
 this.name=file.getName();
 }

 @NotNull @Id(generate=AUTO)
 public Long getId()
 {
 return id;
 }
 public void setId(Long id)
 {
 this.id = id;
 }
 @Length(min=2, max=30)
 public String getName() {
 return name;
 }
 public void setName(String name) {
 this.name = name;
 }
 public UploadedFile getFile() {
 return file;
 }
 public void setFile(UploadedFile file) {
 this.file = file;
 }

}
