Key: TUSCANY-2349
URL: https://issues.apache.org/jira/browse/TUSCANY-2349
Project: Tuscany
Issue Type: Bug
Components: Java SCA Axis Binding Extension, Java SCA Data Binding
Runtime
Affects Versions: Java-SCA-Next
Reporter: Vamsavardhana Reddy
I have a service method that takes a byte array as parameter and returns a byte
array. When I invoke the method using webservice binding, I am getting a

Among other observations, the input and output types (given below) for the
service operation in the generated wsdl seems to be proper.
<xs:element name="negateByteArray">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" minOccurs="0" name="arg0"
nillable="true" type="xs:byte"/>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="negateByteArrayResponse">
<xs:complexType>
<xs:sequence>
<xs:element maxOccurs="unbounded" minOccurs="0" name="return"
nillable="true" type="xs:byte"/>
</xs:sequence>
</xs:complexType>
</xs:element>
