मेरे पास एक वर्ग है जो एक फ़ाइल को https सर्वर से डाउनलोड करेगा । जब मैं इसे चलाता हूं, तो यह बहुत सारी त्रुटियाँ देता है। ऐसा लगता है कि मुझे अपने प्रमाण पत्र के साथ समस्या है। क्या क्लाइंट-सर्वर प्रमाणीकरण को अनदेखा करना संभव है? यदि हां, तो कैसे?

एक बार मुझे यह त्रुटि मिली और हमारी सुरक्षा टीम से संपर्क किया, और यह पता चला कि मुझे JAR को पैच करना था जो हम उपयोग कर रहे थे, क्योंकि हमारी टीम कंपनी द्वारा प्रदान की गई एक पुरानी का उपयोग कर रही थी। किसी अन्य व्यक्ति के लिए बस एक FYI करें जो समान स्थिति में हो।
