Hi all ,
I am trying to upload a file from my machine on to the server and also trying to download the file that has been uploaded to the server . I am using the FileTransferServiceApi for this purpose . But when I run my code I am getting the following exception . Could anyone please help me with this
The exception is
<b>Failed to look up the service: com.sap.engine.services.jndi.persistent.exception
s.NamingException: Exception while trying to get InitialContext. [Root exception is com.sap.engine.services.security.exceptions.BaseLoginException: Cannot creat
