PATCH: fix for null pointer in wsdl2java

[Calvin Smith <ca...@hotmail.com>]

I was getting a nullpointer when I run wsdl2java.
here is the fix:
class: org.apache.axis.wsdl.symbolTable.SymbolTable
method: addMIMETypes
old code:
                if (obj instanceof MIMEContent) {
                    MIMEContent content = (MIMEContent) obj;
                    TypeEntry typeEntry = findPart(op, content.getPart());
                    String dims = typeEntry.getDimensions();
                    if(dims.length() <=0 && typeEntry.getRefType() != null) 
{
                        Node node = typeEntry.getRefType().getNode();
                        if(getInnerCollectionComponentQName(node)!=null)
                            dims += "[]";
                    }
                    String type = content.getType();
                    if(type == null || type.length() == 0)
                        type = "text/plain";
                    bEntry.setMIMEInfo(op.getName(), content.getPart(), 
type, dims);
                }

new code:
                if (obj instanceof MIMEContent) {
                    MIMEContent content = (MIMEContent) obj;
                    TypeEntry typeEntry = findPart(op, content.getPart());
                    String type = content.getType();
                    if(type == null || type.length() == 0)
                        type = "text/plain";
                    String dims;
                    if (typeEntry != null)
                    {
                      dims = typeEntry.getDimensions();
                      if(dims.length() <=0 && typeEntry.getRefType() != 
null) {
                          Node node = typeEntry.getRefType().getNode();
                          if(getInnerCollectionComponentQName(node)!=null)
                              dims += "[]";
                      }
                    }
                    else
                      dims = "[]";
                    bEntry.setMIMEInfo(op.getName(), content.getPart(), 
type, dims);
                }


and here is the offending wsdl.  if this wsdl is wrong and axis was right 
before just let me know.
