WDTypeNotFoundException: type java:byte not found

[Former Member]

Hi,

When I import a webservice I get the following error when I start my Web Dynpro application:

WDTypeNotFoundException: type java:byte not found

(In datatypebroker)

This happens when I import a webservice that contains type xsd:base64Binary. (If I don't map this node to my controller I don't get the error.)

In other posts I read that a conversion using com.sap.engine.lib.xml.util.BASE64Encoder should solve the problem. But the error occurs at startup, before my custom code is reached.

Anyone?

Thanks in advance.

R.,

Please try the following: open generated model class, select necessary property and select "Edit".

Now change type from whatever it is to "binary".

Hi Valery,

Thanks for your reply.

I cannot change the type. When I edit the model class, It does not allow me to change the type.

To be more precise:

The webservice has an import parameter 'FOTO'. This does not appear as a property but as a relation and refers to array_byte.

I can edit the relation (in a popup window), but the only types I'm allowed to change it into are the three nodes under my generated model class: request, response and array_byte.

When I edit array_byte I cannot change the type. There is a property named 'value' of type byte, I cannot change this. I can edit the relation, with the same result as described before.

(When I link the model to my controller context, I get a context node FOTO (cardinality 0:n) that contains an attribute 'value' of type byte.)

I suspect that (Java) Web Dynpro's do not support webservices that contain xsd:base64Binary types.

R.,

Well, is is WebService public?

I mean, can you share WSDL url to let me see what WD generates?

Hi,

Unfortunately it is not.

What we are trying to do is upload an image and have the webservice store the image.

The code fragment in WSDL that causes the error is:

<xsd:element name="DT_A01_H07_UPLOAD_IMAGE_REQ">

<xsd:complexType>

<xsd:sequence>

<xsd:element name="FOTO" type="xsd:base64Binary" />

<xsd:element name="PERSNR" type="xsd:string" />

</xsd:sequence>

</xsd:complexType>

</xsd:element>

Hello, I have exactly the same problem has anyone found a solution?

I saw that one solution is to change the byte[] to a String encodend with Base64, however I do not have the possibility to change the WebService interface, so I have to somehow work with it.

Thanks for any help that you can provide.
