We recently upgraded to 64 Bit Windows/Intel-Xeon workstations. My jboss setup was migrated ovber from the 32 bit machine. I seem to get the, java.lang.UnsatisfiedLinkError: no sapssoext in java.library.path, error all the time now. We are looking for a solution in the DLL set of files that should be in the windows/system32 folder. We are on 2.1.8 JCO and cannot find the DLL set for my computer setup.

Anthony, I’m not sure I understand what you’re trying to achieve. I’m using the LogonTicket (actually, it’s an AssertionTicket which is only valid for 120 seconds) to validate the caller in a non-SAP backend system using web services. I don’t know if SAP EP can be forced to accept a LogonTicket to have some kind of 8h-lasting browser-based SSO. Doesn’t sound to me like something I would want to use in a production environment if that is what you’re up to :-)

Cheers,
Jan

Jan, would it be possible to eliminate the ticket expired class of error (StdErrMessage 4) if we already had a logon ticket, and continuously pass that to the Enterprise Portal before the ticket expires (by default in 8 hours)? So the user supplies the password only once, your program retrieves a valid ticket, then we continuously get a new logon ticket with the previous logon ticket.

This should work as long as mysapcomusesso2cookie in transaction SSO2 is set to 1, I believe.

If true, then another trick77 :-)

HI,
what I cud make out from this discussion is to use this code and along with it, use the SSO2Ticket.java as supplied by SAP in sapext library.
I am using eclipse java perspective and used you code as a java class and second java class is sso2ticket.java.
I put my .dll file in c:/windows/system 32.
but when i run the code i am getting the following error:
Establishing connection to remote server…OK
SAPSSOEXT loaded.
static part ends.

java.lang.UnsatisfiedLinkError: getVersion
at com.mysap.sso.SSO2Ticket.SSO2Ticket.getVersion(Native Method)
at com.trick77.sapsso.TicketSample.main(TicketSample.java:98)
Exception in thread “main”
Please help me with what is missing. I understand that unsatisfiedlink error is coming because of native function declaration in our class. but how to resolve.

Santosh, to me this sounds like an encoding problem.

Cheers

hi,

I am getting a return error of 5:
Ticket syntactically invalid (5);

What could be the reason ?

If I copy the ticket content from the Firefox Browser and run the java class from the OS. I am able to extract details pertaining to the user.

How can you get a SAP logon ticket delivered by the AS Java itselft without a Portal ticket issuer installed? Is this possible?

Looks like a problem with the ticket. Where/How did you obtain it?

I am getting a return error of 1:

“No user provided to function (1)”;

Can’t figure out what the problem could be.

Any suggestions?
