Java: sun.güvenlik.sağlayıcı.certpath.SunCertPathBuilderException: geçerli bir sertifika yolu bulmak için, istenen hedef için açılamıyor
burada bir dosya indirme bir Dersim varhttpsserver. Ben bu çalıştırdığınızda, hata bir sürü verir. Benim sertifika ile ilgili bir sorun var gibi görünüyor. İstemci-sunucu kimlik doğrulaması göz ardı etmek mümkün müdür? Eğer öyleyse, nasıl? Çok teşekkürler.
