Patrick Decat commented on CXF-5428:
------------------------------------
On JBoss EAP 5 with CXF 2.6.13, the services list page generates an exception
when serving the servicelist.css file:
{noformat}

This is due to {{response.getOutputStream()}} being called after
{{response.getWriter()}}:
{noformat:title=http://svn.apache.org/repos/asf/cxf/branches/2.6.x-fixes/rt/transports/http/src/main/java/org/apache/cxf/transport/servlet/servicelist/ServiceListGeneratorServlet.java}
69 public void service(HttpServletRequest request,
…
86 PrintWriter writer = response.getWriter();
87 AbstractDestination[] destinations =
destinationRegistry.getSortedDestinations();
88 if (request.getParameter("stylesheet") != null) {
89 renderStyleSheet(request, response);
90 return;
91 }
…
169 private void renderStyleSheet(HttpServletRequest request,
HttpServletResponse response)
170 throws IOException {
171 response.setContentType("text/css; charset=UTF-8");
172 URL url = this.getClass().getResource("servicelist.css");
173 if (url != null) {
174 IOUtils.copy(url.openStream(), response.getOutputStream());
175 }
176 }
{noformat}
Hence the initial suggestion from the original reporter to move the
{{response.getWriter();}} call.
Should I open a new issue?

Patrick.
