Decompose your Pessoa Class attributes and elements into smaller XSD attributes and elements representing finer functional units
to quote object composition from Wikipedia
object composition (not to be confused with function composition) is a way to combine simple objects or data types into more complex ones. Compositions are a critical building block of many basic data structures, including the tagged union, the linked list, and the binary tree
so Pessoa class could be composed of 'finer-grain' simple-type elements for example assume this namespace space assignment
<schema targetNamespace="http://soapinterop.org/xsd"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:xsd1="http://soapinterop.org Pessoa_Intthis would be represented in the XSD as a simple-type e.g. <xs:simpleType name="Pessoa_Int">
<xs:restriction base="xs:int"/>
</xs:simpleType>
Pessoa_Charthis would be represented in the XSD as a simple-type e.g. <xs:simpleType name="Pessola_Char">
<xs:restriction base="xs:char"/>
</xs:simpleType> Now compose Pessoa class to be composed of the previously created finer grain elements of Pessoa_Ints and Pessoa_Chars<element name="Pessoa">
<complexType>
<sequence><!-- this could be the index -->
<element name="abstract" type="Pessoa_Int"/>
<!-- this could be the name --> <element name="abstract" type="Pessoa_Char"/> </sequence>
</complexType></element> <xsd:import namespace=http://localhost:8080/axis2/schema/unqualified/datatypes schemaLocation="datatypes.xsd" />
now reference the namespace thusly<xsd:schema targetNamespace="http://apache.org/axis2/schema/unqualified/companyService"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:types=http://localhost:8080/axis2/schema/unqualified/datatypes> now your wsdl can itself compose Simple or Complex Elements referencing the previously declared elements of
<types:Pessoa>
<types:Pessoa_Int>
<types:Pessoa_Char> then use WSDL2Java to create your Java Classes from the XSD elements which have been incorporated in the WSDL via the xsd:import Capire?

You mean you are trying to use Complex objects in your interface and you are getting NULL on the way back?
The solution is to wrap all the return complex objects into a ResponseObject and return it from your method.
If its unclear send more information like your service class etcHope this helps,
