I have a stateless session bean called UploadService that handles file uploads. I was able
to use it with no problems for days till I added few setters/getters and a method to scale
the uploaded image.
After login and once a reference of uploadService is encountered, an instantiation
exception is thrown that is caused by " IllegalAccessError: class XYZ cannot access
its superinterface com.truerunes.core.Upload"

I did not include the scale code since it is a bit verbose and might be irrelevant to the
problem. However, you can find the imports used:
| import java.awt.Graphics2D;
| import java.awt.RenderingHints;
| import java.awt.Transparency;
| import java.awt.image.BufferedImage;
| import java.io.ByteArrayInputStream;
| import java.io.ByteArrayOutputStream;
| import java.io.IOException;
| import java.io.InputStream;
| import java.io.OutputStream;
| import java.util.Date;
|
| import javax.ejb.Stateless;
| import javax.imageio.ImageIO;
| import javax.persistence.EntityManager;
|
| import org.jboss.seam.annotations.Factory;
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Logger;
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.Out;
| import org.jboss.seam.annotations.security.Restrict;
| import org.jboss.seam.log.Log;
|
| @Stateless
| @Name("uploadService")
| public class UploadService implements Upload {
|
| @Logger Log log;
|
| @In(create = true, value = "entityManager")
| private EntityManager em;
|
| private byte[] data;
| private String contentType;
| private String fileName;
| private String title;
| private int size;
|
| // setters/getters omitted.
|
| @Restrict("#{s:hasRole('gsadmin')}")
| public void upload() {
| }
|
| private byte[] scale(){
| }
| }
|
here is the page that references the uploadService component:
| <h:form id="registration-form"
enctype="multipart/form-data">
| <span class="error"><h:messages
globalOnly="true"/></span>
| <s:validateAll>
| <fieldset>
| <legend>Enter file to upload</legend>
| <div>
| <h:outputLabel for="title" value="Title"/>
| <h:inputText styleClass="input-field" id="title"
required="true"
| value="#{uploadService.title}" size="40"
maxlength="40"/>
| <h:message styleClass="error" for="title"/>
| </div>
| <div>
| <h:outputLabel for="artwork" value="Artwork"/>
| <s:fileUpload id="artwork" styleClass="input-field"
| data="#{uploadService.data}" accept="image/*"
| contentType="#{uploadService.contentType}"
| fileName="#{uploadService.fileName}"
fileSize="#{uploadService.size}"
| size="40" maxlength="40" required="true"/>
| <h:message styleClass="error" for="artwork"/>
| </div>
| </fieldset>
|
| <div class="submit-buttons">
| <h:commandButton value="Upload"
| action="#{uploadService.upload}" id="registerButton"/>
| </div>
| </s:validateAll>
| </h:form>
|
I tried updating from JDK 5 to JDK 6, rebuilding and removing the old deployed archive but
the problem is still there.
