I am trying to unit test an upload call but I get this error for the following code:
@MultipartConfig(maxFileSize = 3145728)
class WebServlet extends ScalatraServlet with FileUploadSupport {
override def isSizeConstraintException(e: Exception) = e match {
case se: ServletException if se.getMessage.contains("exceeds max filesize") ||
se.getMessage.startsWith("Request exceeds maxRequestSize") => true
case _ => false
}
error {
case e: SizeConstraintExceededException => RequestEntityTooLarge("too much!")
}
post("/uploadscript") {
val privateParam = try {params("private") != null && params("private").equals("true") } catch { case _ => false }
println("privateParam = " + privateParam)
val file = fileParams("file")
println(s"The size of the file is ${file.size}")
}
The error is:
java.lang.IllegalStateException: No multipart config for servlet
at org.eclipse.jetty.server.Request.getParts(Request.java:2064) ~[jetty-server-8.1.10.v20130312.jar:8.1.10.v20130312]

And this is my unit test, and the first one succeeds, so it is finding my webservice:
class WebServletSpecification extends MutableScalatraSpec {
addServlet(classOf[WebServlet], "/*")
"GET /hello" should {
"return status 200" in {
get("/hello/testcomputer") {
status must_== 200
}
}
}
"POST /uploadscript" should {
"return status 200" in {
val scriptfile = "testfile"
val scriptname = "basescript"
post("/uploadscript", Map("private" -> "true"), Map("file" -> new File(scriptfile))) {
status must_== 200
}
}
}
}
I am running this inside of Eclipse and I am not certain what is going on.
It works fine with using HttpPost
and MultipartEntity
so it seems to be a problem with Eclipse or how the scalatra specification framework works.
Any idea what may be going wrong?
I don't have a separate web.xml.
I am only using jetty 8.1.10, as seen from what I use in build.sbt:
"org.eclipse.jetty" % "jetty-webapp" % "8.1.10.v20130312" %
"container"
,
This is the solution I found when using ServletContextHandler and not WebAppContext. From here : https://bugs.eclipse.org/bugs/show_bug.cgi?id=395000
import org.eclipse.jetty.server.Handler;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.server.handler.HandlerList;
import org.eclipse.jetty.servlet.ServletContextHandler;
import org.eclipse.jetty.servlet.ServletHolder;
import javax.servlet.MultipartConfigElement;
public class WebServer {
protected Server server;
public static void main(String[] args) throws Exception {
int port = 8080;
Server server = new Server(port);
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
ServletHolder fileUploadServletHolder = new ServletHolder(new FileUploadServlet());
fileUploadServletHolder.getRegistration().setMultipartConfig(new MultipartConfigElement("data/tmp"));
context.addServlet(fileUploadServletHolder, "/fileUpload");
server.setHandler(context);
server.start();
server.join();
}
}
In case anyone else is looking for this in Jetty 9:
Add this to the request.handle( ... )
MultipartConfigElement multipartConfigElement = new MultipartConfigElement((String)null);
request.setAttribute(Request.__MULTIPART_CONFIG_ELEMENT, multipartConfigElement);
The @MultipartConfig
is a Servlet spec 3.0 annotation.
You'll need to add the appropriate artifacts and configuration to support annotation in your Jetty environment.
You'll want the jetty-annotations
and jetty-plus
artifacts.
Then you'll want to setup the test server with the appropriate configurations.
like this...
(I don't know the Scala specifics here, sorry)
package com.company.foo;
import org.eclipse.jetty.annotations.AnnotationConfiguration;
import org.eclipse.jetty.plus.webapp.EnvConfiguration;
import org.eclipse.jetty.plus.webapp.PlusConfiguration;
import org.eclipse.jetty.server.Server;
import org.eclipse.jetty.webapp.Configuration;
import org.eclipse.jetty.webapp.FragmentConfiguration;
import org.eclipse.jetty.webapp.MetaInfConfiguration;
import org.eclipse.jetty.webapp.TagLibConfiguration;
import org.eclipse.jetty.webapp.WebAppContext;
import org.eclipse.jetty.webapp.WebInfConfiguration;
import org.eclipse.jetty.webapp.WebXmlConfiguration;
public class EmbedMe {
public static void main(String[] args) throws Exception {
int port = 8080;
Server server = new Server(port);
String wardir = "target/sample-webapp-1-SNAPSHOT";
WebAppContext context = new WebAppContext();
context.setResourceBase(wardir);
context.setDescriptor(wardir + "WEB-INF/web.xml");
context.setConfigurations(new Configuration[] {
new AnnotationConfiguration(), new WebXmlConfiguration(),
new WebInfConfiguration(), new TagLibConfiguration(),
new PlusConfiguration(), new MetaInfConfiguration(),
new FragmentConfiguration(), new EnvConfiguration() });
context.setContextPath("/");
context.setParentLoaderPriority(true);
server.setHandler(context);
server.start();
server.join();
}
}
This is from the https://github.com/jetty-project/embedded-servlet-3.0 example project.
