I have a web application running on Tomcat 5.0.
One of the features is this appln enables file upload. After an upload, If I
stop and restart the server , I get this particular expception.
SEVERE: IOException while loading persisted sessions:
java.io.WriteAbortedException: writing aborted; java.io.
NotSerializableException:
org.apache.commons.fileupload.DeferredFileOutputStream

As a solution that I found , I added this to the server.xml of Tomcat.
<Manager className="org.apache.catalina.session.StandardManager"
pathname=""/>
Can someone tell me what could be the root of this problem.
