s:fileupload OutOfMemory

[toni]

Hi,

I'm using s:fileupload with Seam 1.1.6 to upload files. The problem is that I run into outofmemory, when I try to persist the entity.

The maximum heap size has been set to 2048 mb. The files are around 120 mb big. Any way how I can configure seam and/or hibernate so that I don't run into OutOfMemory errors?

The entity bean:

@Name("pictureArchive")
@Entity

public class PictureArchive implements Serializable
{
  @Id
  @GeneratedValue(strategy = GenerationType.IDENTITY)
  long id;

  String fileName;

  @Lob
  @Basic(fetch = FetchType.LAZY, optional = true)
  byte data[];


  public long getId()
  {
    return id;
  }

  public void setId(long id)
  {
    this.id = id;
  }

  public String getFileName()
  {
    return fileName;
  }

  public void setFileName(String fileName)
  {
    this.fileName = fileName;
  }

  

  public byte[] getData()
  {
    return data;
  }

  public void setData(byte[] data)
  {
    this.data = data;
  }

}

The jsp code:

<f:view>

  <title></title>

  <%@ include file="common/top.jsp" %>

  <h1></h1>

  <h2></h2>

  <div id="body">


    <h:form id="upload" enctype="multipart/form-data">

      <s:fileUpload data="#{fileUploadBean.file}" accept="" fileName="#{fileUploadBean.name}"/>

  
      <h:commandButton value="Upload" action="#{fileAction.uploadFile}"/>

    </h:form>

  </div>

  <%@ include file="common/bottom.jsp" %>
</f:view>

The relevant function in the session bean:

  public String uploadFile()
  {
    log.info("Call to uploadFile");
    if (fileUploadBean.getFile() != null)
    {
      log.info("Size: " + fileUploadBean.getFile().length);

      PictureArchive pictureArchive = new PictureArchive();
      pictureArchive.setData(fileUploadBean.getFile());    
      pictureArchive.setFileName(fileUploadBean.getName().replaceAll("^.*[\\\\/]", ""));
      entityManager.persist(pictureArchive);
      return "files";
    }
    return "file";
  }
