Hi Anne
By "simple type", do you mean "primitive type"? Such as int (note, no package) vs. java.lang.Integer? There is no primitive type for a String, it is always an instance of the class java.lang.String. I have been developing in java for 5 years, and am also a lecturer on the subject - So unless i've been missing something big, I don't think that's it :-)
But your comment holds true: This is generated code, so this must be a bug - though I need to find out if anybody else has used String attributes in axis? (Specifically 1.2RC)

In Java, "string" is a simple type; "String" is not. The question is why did Axis map your CurrencySymbolT type to "String" rather than "string", and since it did so, why does the code expect a simple type. Since this is all generated code, I'd say this is a bug. Please file a bug report.
As a work around, you could try modifying your bean and define CurrencySymbol as type java.lang.string. (This may cause other problems in the serializer, though.)

Subject: Help! String xs:attributes not supported?
(java.lang.reflect.InvocationTargetException)
Hi, I have a serious problem with Axis 1.2 - in my schema (which I have no control over), I basically have a type which represents a currency: It's a complex type, with a xs:string attribute for Currency Symbol:
<complexType name="CurrencyT"> <sequence> <element minOccurs="1" maxOccurs="1" name="Value" type="i0:CurrencyValueT" /> </sequence> <attribute form="qualified" use="required" name="CurrencySymbol" type="i0:CurrencySymbolT" /> </complexType>
and
<simpleType name="CurrencySymbolT"> <restriction base="string"> <pattern value="(\S){1,3}" /> </restriction> </simpleType>
Everything is document/literal in the schema.
wsdl2java compilation runs perfectly (and infinitely better than Sun's crap implementation) - and my service compiles and deploys fine. When, however, I request the WSDL from <service_name>?wsdl I get the following error: (the second part ['Caused by'] is the interesting bit):

Why does it seem that Axis does not like the idea of String being a simple type? (which a String attribute must surely be). It's not a matter of Java primitive types or not - if I change that attribute to either xs:integer (java.lang.Integer) or xs:int (Java: int) everything goes well, so it's specifically the String that's causing issues.
I have switched our project over to Axis (from JAX-RPC SI) in an
emergency, and now I'm having these issues (placing it at risk) - if anybody
can help me resolve them I shall be most grateful.
