जावा में सरल SOAP क्लाइंट लागू करने के लिए, आप SAAJ फ्रेमवर्क का उपयोग कर सकते हैं (इसे JSE 1.6 और इसके बाद के संस्करण के साथ शिप किया गया है):
जावा (SAAJ) के लिए SOAP अटैचमेंट एपीआई के साथ मुख्य रूप से SOAP अनुरोध / रिस्पॉन्स संदेशों के साथ सीधे निपटने के लिए उपयोग किया जाता है जो किसी भी वेब सेवा एपीआई में पर्दे के पीछे होता है। यह डेवलपर्स को JAX-WS का उपयोग करने के बजाय सीधे साबुन संदेश भेजने और प्राप्त करने की अनुमति देता है।
SAAJ का उपयोग करके SOAP वेब सेवा कॉल का कार्यशील उदाहरण (इसे चलाएं!) देखें। यह इस वेब सेवा को कॉल करता है ।
