The Struts dispatcher cannot be found.
Hello, Struts version 2.5.17 I am trying to setup struts 2 on tomcat, but there is coming up an error. The .jsp was opened directly. If there are more files needed to figure out what is wrong, feel free to ask. Error-message: HTTP Status 500 – Internal Server Error Type Exception Report Message An exception occurred processing JSP page /web/welcome.jsp at line 15 Description The server encountered an unexpected condition that prevented it from fulfilling the request.

RE: Struts2 - multipart/related - HttpServletRequest#getParts not working
I see Struts REST plugin has a handler for multipart request but it and even
the whole Struts framework also talks only about multipart/form-data ;)
Unfortunately it seems Struts doesn't know such content type at all. Anyway,
some tips can be found in net via googling "UT010016: Not a multi part request".
Regards.

Re: Struts2 - multipart/related - HttpServletRequest#getParts not working
Hi Yesser, thanks for your response. Yes, it is the issue with the
servlet. I am suspecting that MutiPartConfig works only for
multipart/form-data and does not work with multipart/related. I passed
the request directly to HttpServlet instead of Sturts mapped Action with
@MultiPartConfig configured and I got the exception:
javax.servlet.ServletException: UT010016: Not a multi part request.
Almost all documentation I saw talks only about multipart/form-data.
I am assuming using Struts rest plugin also will not help in this case.
Kindly let me know.
Best regards,
Nikhil P kookkiri

Subject: Struts2 - multipart/related - HttpServletRequest#getParts not working
I have request coming from another application which is 'multipart/related'. In
the mutlipart request body, I am receiving image/jpeg and application/xml. I
suppose, I should be iterating over the http part obtained from getPaths method
in the HttpServletRequest object and read the stream available on each of the
parts. When I try doing that, I am getting the following error:
java.lang.IllegalStateException: UT010057: multipart config was not present on
Servlet ERROR [stderr] (default task-2) at
io.undertow.servlet//io.undertow.servlet.spec.HttpServletRequestImpl.verifyMul
tipartServlet(HttpServletRequestImpl.java:523)
ERROR [stderr] (default task-2) at
io.undertow.servlet//io.undertow.servlet.spec.HttpServletRequestImpl.getParts(
HttpServletRequestImpl.java:512)
ERROR [stderr] (default task-2) at
javax.servlet.api//javax.servlet.http.HttpServletRequestWrapper.getParts(HttpSer
vletRequestWrapper.java:375)
Please let me know the best possible solution for this.
Here is what I am doing in the code:
public class TestMultiPart extends ActionSupport implements
ServletRequestAware
{
private InputStream inputStream;
private HttpServletRequest request;
public String execute()
{
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try
{
Collection parts = request.getParts();
for(Part part : parts)
{
String contentType = part.getContentType();
System.out.println("Content type is: " + contentType);
File file = getFileToDownload(getContentType(contentType));
if(file != null)
{
bis = new
BufferedInputStream(request.getInputStream());
bos = new BufferedOutputStream(new FileOutputStream(file));
byte[] bytes = new byte[bis.available()];
while(bis.read(bytes) > 0)
{
bos.write(bytes);
bos.flush();
bytes = new byte[bis.available()];
}
}
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ServletException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
if(bis != null)
{
try {
bis.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
if(bos != null)
{
try {
bos.close();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
inputStream = new
ByteArrayInputStream("200".getBytes(StandardCharsets.UTF_8));
return SUCCESS;
}
public InputStream getInputStream() {
return inputStream;
}
public void setInputStream(InputStream inputStream) {
this.inputStream = inputStream;
}
@Override
public void setServletRequest(HttpServletRequest requestObject)
{
this.request = requestObject;
}
}
