धन्यवाद
वाह। यह बहुत सारे कोड है। क्या आप वाकई एक [न्यूनतम पूर्ण सत्यापन योग्य उदाहरण] (http://stackoverflow.com/help/mcve) है, न्यूनतम पर जोर? एक न्यूनतम उदाहरण बनाना दूसरों को आपकी त्रुटि की अधिक तेज़ी से पहचानने में सहायता करता है और आपको समस्या को स्वयं ढूंढने में भी मदद कर सकता है। – Cecilia
क्षमा करें, मैं समस्या को अधिक आसानी से ढूंढने के लिए जितना संभव हो उतना अधिक जानकारी देने की कोशिश कर रहा था। यदि आप पोम पर ध्यान देते हैं, वेब और सर्वलेट संदर्भ xml फ़ाइलें आवश्यक हैं क्योंकि त्रुटि हो सकती है, इसके अलावा आप त्रुटि लॉग भी पा सकते हैं जो कि महत्वपूर्ण है और दो वर्ग फाइलें जो ठीक थीं, मैंने उन्हें पूर्ण प्रारूप में रखा क्योंकि समस्या उन दो फाइलों के नीचे थी। वैसे भी धन्यवाद –
