I found out at http://jcs.mobile-utopia.com/jcs/6622_CertificateException.java that 'Certificate was issued by an unrecognized entity' is the most important reason. The reason says: UNRECOGNIZED_ISSUER
At http://www.j2meforums.com/forum/index.php?PHPSESSID=2f414d70a50123a17b390d7debf7f65b&action=printpage;topic=8492.0 I found out that it also may be related to the j2me environment (or the WTK toolkit environment). The way it handles certificates may be the issue. For me the problem is not yet solved unfortunately. In the stack trace i found out that I indirectly use a X509 certificate. When I looked at http://en.wikipedia.org/wiki/X.509#Sample_X.509_certificates i found out what it was what I needed: a certificate with indeed an issuer. Probably I must create a signed certificate or so... How does google implement x509 certificates? And why is it sometimes working and sometimes not? I guess a certificate runs out of date after a while??? On Dec 28, 10:26 pm, hs <[email protected]> wrote: > Hello, I'm working at a J2ME implementation of the google API for > calendar information.
