i new spring integration , while working project requirement. facing below issue marshall pojo(java object) soap response(using spring integration ws): please find below details same:
i have sample xsd file below:
</xsd:element> <xsd:element name="myuserresponses"> <xsd:complextype> <xsd:sequence> <xsd:element minoccurs="0" maxoccurs="unbounded" name="myuserresponse" type="tns:myuserresponse" /> </xsd:sequence> </xsd:complextype> </xsd:element> <xsd:complextype name="myuserresponse"> <xsd:sequence> <xsd:element minoccurs="0" maxoccurs="1" name="somenumber" type="xsd:string"/> <xsd:element minoccurs="0" maxoccurs="1" name="referenceid" type="xsd:string" /> </xsd:sequence> </xsd:complextype> </xsd:schema>
i have created below java object files using xjc compiler:

my soap request below:
<soapenv:envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:sch="http://tempuri.org/"> <soapenv:header/> <soapenv:body> <sch:myuserrequest> <sch:somenumber>8009618916</sch:somenumber> <sch:referenceid>referenceidreferenceid</sch:referenceid> </sch:myuserrequest> </soapenv:body> </soapenv:envelope> again receive proper response(one record) if changes in xsd file getting single record , corresponding changes in java object file created face issue when try multiple record response.
please me find doing mistake or missing something.
just quote link got:
the above exception occurs because jaxb expects @xmlrootelement annotation on entity, gets marshal. mandatory , can not skipped. @xmlrootelement annotation required meta data root element of xml marshalled java object. arraylist class or java collection class not have jaxb annotations on it. due jaxb unable parse such java objects , raises error.
[solved]: javax.xml.bind.jaxbexception: class java.util.arraylist nor of super class known context
seems myuserresponse not have @xmlrootelement annotaion.
