View state is not maintained for transient instance variables  and static variables also. Then what exactly is the difference between transient instance variable and  static variable ?

Hi All,


I have tried invoking Apex (SOAP based) web service by sending out bound message , but it's throwing error :

" INVALID_SESSION_ID: Invalid Session ID found in SessionHeader: Illegal Session"





I've created a Outbound XML Message for the Lead object that only sends the Id,  Name,Source,Industry and Date Of Creation. Whenever I trigger it, I get this error in the Outbound Message Delivery Status Page:

org.xml.sax.SAXException: Processing instructions are not allowed within SOAP messages

Can anyone please help me abou that also about the SOAP messages ??

Hi everyone,

I don't know if it's possible or not. I know we can create apex class that used as web service and get the wsdl using generate wsdl from salesforce setup. I want to know if the apex class that I created as web service can be call from url ? Is it possible to call from outside salesforce instance ? any suggestions would be great
