> ==========================================
> Things go well until 'Team1' (the second complextype) is about to be
> processed, at which point the 'unexpected subelement' runtime exception
> occurs.
> I'll dive in and take a gander at what's going on - please forgive. It seems
> the generated code is unaware of the nested/complex nature of the
> 'StadiumInfo' element as relates to advancing to the next starting element,
> so when it tries to 'climb out/up' the tree to find the next sibling, it
> doesn't make it. So, instead of being positioned at the closing 'StadiumInfo'
> tag upon returning from parsing the 'StadiumInfo' element, it is somewhere a
> bit deeper - maybe at the whitespace just before the closing 'StadiumInfo'
> tag. The pre-ordained sequential processing means that the next element
> sought, in our case 'Team1', will not be found and the RuntimeException
> occurs.
> I was able to get past this error in a couple of ways:
> 1) Adding a couple more 'reader.next();' statements just above the test
> looking for the start of the next element. These statements must be inserted
> after processing all complex types.
> 2) Changing the 'reader.next()' paradigm into one that doesn't pay any
> attention to depth level or complex types, but just looks at every 'next()'
> element until it satisfies the conditions we're looking for - that is, that
> the next starting element we find has the name we want.
> Here is the generated code for a typical (simple/not-complex) element.
> // do certain number of 'reader.next()' calls to skip
> whitespace/comments/etc., then hope you're in the right place in the tree (my
> comment)
> if (reader.isStartElement() &&
> new javax.xml.namespace.QName(
> "http://www.dataaccess.nl/wk2006";,
> "sDescription").equals(
> reader.getName())) {
> // process the current element (my comment)
> java.lang.String content = getElementTextProperly(reader);
>
> object.setSDescription(org.apache.axis2.databinding.utils.ConverterUtil.convertTostring(
> content));
> And here is another way that I hacked the generated code to get it going:
> // what is the qualified name of the next element we're
> looking for? (my comment)
> javax.xml.namespace.QName qname = new
> javax.xml.namespace.QName("http://www.dataaccess.nl/wk2006";, "sDescription");
> // keep moving ahead until you find the element you're
> looking for (my comment)
> while ( ! ( reader.isStartElement() &&
> qname.equals(reader.getName())) ){
> reader.next();
> }
> // process the current element (my comment)
> java.lang.String content = getElementTextProperly(reader);
>
> object.setSDescription(org.apache.axis2.databinding.utils.ConverterUtil.convertTostring(
> content));
> That's it.
