---------------------------------
Summary: Cannot call getOutputStream(), getWriter() already called
Key: WFLY-3281
URL: https://issues.jboss.org/browse/WFLY-3281
Project: WildFly
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Web (Undertow)
Affects Versions: 8.1.0.CR1
Environment: linux
Reporter: Jakob Munih
Assignee: Stuart Douglas
Priority: Minor
Similar to WFL-1276 I got “UT005023: Exception handling request to /hsb/web-services/: java.lang.IllegalStateException: UT010005: Cannot call getOutputStream(), getWriter() already called” when accessing CXFNonSpringServlet servlet that shows all web services deployed with ApacheCamel 2.13.0. The exception is was not present in WF 8.0. Even with the exception the servlet renders all available service correctly.
Servlet:
{code}
import com.parsek.hsb.commons.Hsb;
import org.apache.cxf.Bus;
import org.apache.cxf.transport.servlet.CXFNonSpringServlet;
import javax.inject.Inject;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
// reuse camel bus
@WebServlet(value = "/web-services/*", name = "HsbWebServices", asyncSupported = true, loadOnStartup = 1)
public class ExposeCxf extends CXFNonSpringServlet {
@Hsb
@Inject
private Bus bus;
@Override
public void init(ServletConfig sc) throws ServletException {
setBus(bus);
super.init(sc);
}
}
{code}
Exception
