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.

Posted by Anne Thomas Manes <an...@manes.net>.
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.)
