Hi all,
I am trying to get a FileInputStream object on a EJB bean. Because
FileInputStream doesn't implement serializable interface so I created a
class that contains FileInputStream object and implements writeObject() and
readObject
Following is the class
***********************************************
public class ASIFileInputStream implements Serializable {
private FileInputStream fis = null;
public ASIFileInputStream(File dbFile) throws IOException {
fis = new FileInputStream(dbFile);
}
public void writeObject() throws IOException {
FileOutputStream fos = new FileOutputStream("asitest");
ObjectOutputStream out = new ObjectOutputStream(fos);
out.writeObject(fis);
out.flush();
}
public void readObject() throws IOException, ClassNotFoundException
{
FileInputStream fi = new FileInputStream("asitest");
ObjectInputStream ois = new ObjectInputStream(fi);
fis = (FileInputStream)ois.readObject();
}
public FileInputStream getFileInputStream() {
return fis;
}
}
****************************************************************************
I am creating an object of above class inside EJB Bean and calling
writeObject() method to write FileInputStream data. And Finally returning
ASIFileInputStream object from ejb function.
Now I use the following code to call ejb and get that FileInputStream
***********************************************************
InitialContext context = new InitialContext(environment);
Object obj =
context.lookup("java:comp/env/ejb/asi.XMLDataFile");
XMLDataFileHome dataFileHome =
(XMLDataFileHome)javax.rmi.PortableRemoteObject.narrow(obj,
XMLDataFileHome.class);
XMLDataFile file = dataFileHome.create("");
ASIFileInputStream afis =
file.getXMLDataFile(dsFullPath);
afis.readObject();
FileInputStream fis = afis.getFileInputStream();
*****************************************************************
But it fails and return nothing.
Has anybody ever tried sending FileInputStream or any other stream through
EJB.
Thanks for help in advance.
