How to supply an in memory document for signing to the applet

I use the eid-applet for signing a document.  This document is an in memory 
string. To supply the document to the applet, I create a stateful session bean 
(ejb3) that implements the eid-applets SignatureService interface 
(be.fedict.eid.applet.service.spi.SignatureService). In my webapp I create the 
ejb and set the document to sign using a setter from the stateful session bean. 
The applet calls the servlet that (should) create the same ejb. Unfortunately 
this ejb is not the same instance of this stateful session bean. How can I get 
the document (in memory string) from the session of the webapp (struts action) 
into the applet for signing.

This is the code of the stateful session bean I use :

@Stateful(name = "DocumentSignatureService")
@Local(DocumentSignatureService.class)
public class DocumentServiceBean  implements DocumentSignatureService {

    ...

    public void setDocument(byte [] doc) {
        ...
    }
    @Remove
    public byte [] getSignature() {
        ...
    }

    @Override
    public byte[] getDocument() {
        return doc;
    }

    @Override
    public void setSignature(byte[] sig) {
        ...
    }

    @Override
    public String getFilesDigestAlgorithm() {
        return null;
    }

    @Override
    public void postSign(byte[] arg0, List<X509Certificate> arg1) 
        throws ... {
        ...
    }

    @Override
    public DigestInfo preSign(List<DigestInfo> arg0,
                              List<X509Certificate> arg1) throws ... {
        return null;
    }
}

public interface DocumentSignatureService extends SignatureService {
    byte [] getDocument();
    void setDocument(byte [] doc);
    byte [] getSignature();
    void setSignature(byte[] sig);
}
