How to get all additional attributes of Magento Product without explicitly specifying them

Question

My goal is to get and display all additional attributes for the Magento product using SOAP API. For example Gender, Shirt Size and Color for T-Shirt product. But the program shouldn't know the attribute names.

In the SOAP Call: catalogProductInfo there is additional attributes parameter and it looks like I have to explicitly specify additional attribute names.

I am using Java and Apache Axis to connect to Mangeto SOAP API and the code is following:

stub.catalogProductInfo(sessionId, "118", null, null);

call declaration:
public com.magentocommerce.api.CatalogProductReturnEntity catalogProductInfo(java.lang.String sessionId, java.lang.String productId, java.lang.String storeView, com.magentocommerce.api.CatalogProductRequestAttributes attributes) throws java.rmi.RemoteException {

attributes parameter constructor declaration:
public CatalogProductRequestAttributes(
       java.lang.String[] attributes,
       java.lang.String[] additional_attributes) {

But I have to specify last parameter somehow to get all additional attributes. Is it possible to do through SOAP API?

Update: "*" as attribute doesn't work

CatalogProductRequestAttributes attrs = new CatalogProductRequestAttributes();
attrs.setAttributes(new String[] {"*"});
attrs.setAdditional_attributes(new String[] {"*"});

Resulted object is not filled neither with standard attributes nor with additional attributes.

Answer 1

I haven't tried through the API specifically, but have you tried specifying * as the attribute name? That's how it's done in the framework itself.
