Hi All, Recently I came across a weird issue where in getChildnodes call in xerces library was not thread safe. I have a small Servlet based application where in i had a xml document in every users session ( this is created by cloning a empty xml document ). So sometimes I see the call getchildNodes() was throwing ClonebinTree error. Does anyone know if its ok to use a XML document in session or is it not advisable. Does anyone know if getchildnodes or any other calls being not thread safe ??? I have done all checks in my servlet and at no point we have any xml as globally shared - e.g. static calls etc. But the GetChildNodes call in xerces seems to be statis and has a static member variable of document type. any he   More>>
