Problem in accessing the web service through https

We have web service written in java that can be successfully invoked through normal http using EasySoap. But having problem invoking through https.

Getting this error.

It is working well with SoapUI through https.

We have PB 11.5 professional and we are testing web services with PowerBuilder 12.5.2 Build 5006 Evaluation software.

Please help.

Thanks,

John
