SSO2Ticket within servlet filter - Orionserver

Question

Hi,
I need to validate user that already logged in via SAP portal.
So I get ticket as cookie.
I read this cookie and try to validate it with SSO2Ticket.java that is JNI wrapper for C application.
For this I put 2 files in system32 folder: sapssoext.dll and sapsecu.dll and I register first one with regsvr32.
Now I try to run SSO2Ticket.java and it works perfectly. But I need this functionality inside my login servlet filter.
So I still use SSO2Ticket.java but in stead of main method I put same calls into may filter.
It seams to load sapssoext.dll but what ever method I call I get:
java.lang.UnsatisfiedLinkError
Here is method that performs calls. Method is called from filter doFilter method.
There is SSO2Ticket.java attached here.
private void checkSAPTicket(HttpServletRequest request) throws Exception
System.out.println("checkSAPTicket");
//Ticket is hardcoded and valid
String ticket="AjExMDAgABNwb3J0YWw6U0VEQVZJRFNTT05QiAATYmFzaWNhdXRoZW50aWNhdGlvbgEADFNFREFWSURTU09OUAIAAzAwMAMAA0hTMQQADDIwMDYxMjE1MDgwOQUABAAAAAgKAAxTRURBVklEU1NPTlD/APUwgfIGCSqGSIb3DQEHAqCB5DCB4QIBATELMAkGBSsOAwIaBQAwCwYJKoZIhvcNAQcBMYHBMIGAgEBMBMwDjEMMAoGA1UEAxMDSFMxAgEAMAkGBSsOAwIaBQCgXTAYBgkqhkiG9w0BCQMxCwYJKoZIhvcNAQcBMBwGCSqGSIb3DQEJBTEPFw0wNjEyMTUwODA5NTFaMCMGCSqGSIb3DQEJBDEWBBRhLnWWaKW8yXyGSrs6gBTC97XnlTAJBgcqhkjOOAQDBC8wLQIUQrgjCpKQeEScuFP7rGWO7V76b5ICFQCT0WhSpqIB11L+HVLmyAjcWeUlw==";
// get PAB (public key) of issuing system. It is in root of my app server
File pab=new File("verify.pse");
String pabFilePath=pab.getAbsolutePath();
System.out.println("pabFilePath="+pabFilePath);
Object [] o=null;
File sapsecu=new File("sapsecu.dll");
String ssf_library=sapsecu.getAbsolutePath();
System.out.println("ssf_library="+ssf_library);
try
String version =SSO2Ticket.getVersion();
//String ssf_library="sapsecu.dll";
if(!SSO2Ticket.init(ssf_library)) {
System.out.println ("Could not load library: " + ssf_library);
return;
System.out.println("evalLogonTicket call...");
// Validate logon ticket.
o = SSO2Ticket.evalLogonTicket (ticket, pabFilePath, null);
} catch (Exception e) {
System.out.println(e);
} catch (Throwable te) {
System.out.println(te);
System.out.println("evalLogonTicket call ended...");
And the log I get when I run this:
checkSAPTicket
pabFilePath=C:\project\GSS\orion-2.0.2\verify.pse
ssf_library=C:\project\GSS\orion-2.0.2\sapsecu.dll
SAPSSOEXT loaded.
static part ends.
java.lang.UnsatisfiedLinkError: getVersion
evalLogonTicket call ended...
Could not validate SAP login ticket from HTTP Header.
If I omit call SSO2Ticket.getVersion(); than the same exception is for SSO2Ticket.init(ssf_library).

Hi,
I think java.lang.UnsatisfiedLinkError means that it cannot find the .dll files.
I am not sure it will find them even if the are registered with regsvr32.
Have you tried placing the .dll files somewhere in the classpath ?
