Hello! I am using JBoss 4.0.4 with jbossws 1.0.3GA. I am developing a WS DII client which talks with a third party Web Service. I am having problems serializing one field which is specified as "base64Binary" on the WSDL: <xsd:complexType name="BinaryData"> <xsd:sequence> <xsd:element name="data" type="xsd:base64Binary" nillable="true"/> <xsd:element name="mimeType" type="xsd:string" nillable="true"/> <xsd:element name="URL" type="xsd:string" nillable="true"/> <xsd:element name="removeOnUpdate" type="xsd:boolean" nillable="false"/> </xsd:sequence> The "data" field should be sent as a Base64 String. Although, the Request SOAP message has the following data: <ns1:data xmlns:ns1="urn:drm/ingest-ex/IngestService/SchemaTypes"> <ns1:data>-1</ns1:data> <ns1:data>-40</ns1:data> <ns1:data>-1</ns1:data> <ns1:data>-32</ns1:data> ...... <ns1:mimeType>image/jpeg</ns1:mimeType> <ns1:URL xsi:nil="1"/> <ns1:removeOnUpdate>false</ns1:removeOnUpdate> </ns1:data> I have implemented a client using jboss.net (org.jboss.axis...) and I have the same problem. I have implemented a standalone client using axis (org.apache.axis...) and I can call the Web Service correctly. The Request SOAP message contains: < data> < data>j/4AAQSkZ..... < mimeType>image/gif < URL xsi:nil="true"/> < removeOnUpdate>false < /data> In this case, the "data" field is correctly encoded as a Base64 String. Am i missing any configuration with jbossws? What must I do to have the correct behavior? Any help would really be appreciated.
