I don't understand Session scope, but the difference between Request and Application scope is pretty simple: Request scope means each thread in the router servlet has its own copy of the service class; Application scope means each thread shares a single instance of the service class. Therefore in Application scope your service class must be threadsafe. If it isn't, you could see problems like the one below...for example if one thread nulls-out a variable that another thread tries to use. -Don >I have scope set to Application, could that be the reson for this error: > >Fault Code = SOAP-ENV:Server >Fault String = Exception from service object: SQL=[null]: Unable to create >query: Java.lang.NullPointerException > >It dosn't occur the first time I run it, and maybe not the second time - but >then it gives this error. > >Med venlig hilsen/Best regards >S�ren Neigaard >------------------------------- >Mobilethink A/S >Arosgaarden >�boulevarden 23, 5.sal >DK - 8000 �rhus C >Telefon: +45 86207800 >Direct: +45 86207810 >Fax: +45 86207801
