Cannot use Fileupload Multipart on Weblogic server

I'm having a blocking exception while requesting the servlet parts in Weblogic 12.2.1.4-dev on docker.(please note that this is working on Wildfly server)
The Java code i'm using is:
import javax.servlet.http.*;
protected void doPut(HttpServletRequest request, HttpServletResponse response) throws IOException {
...
Collection<Part> parts = request.getParts();
...
}
the error i'm having in the server.log:
<Oct 2, 2020 9:17:59,302 AM GMT> <Warning> <HTTP> <BEA-101394> <The exception "The request content-type is not a multipart/form-data" occurred when processing getParameter or getParameterValues from a multipart value of a ServletRequest.>

And the Http request details on google chrome:

I faced the same issue.
FileUpload's servlet implementation from WebLogic core libs only allow multipart requests under "POST" method:
private boolean isMultipart() {
if (!this.request.getMethod().toLowerCase().equals("post"))
return false;
String contentType = this.request.getContentType();
if (contentType == null)
return false;
if (contentType.toLowerCase().startsWith("multipart/form-data"))
return true;
return false;
}
If this validation fails, it will throw an exception including a message that does not have any relation with the actual error:
if (!isMultipart())
throw new ServletException("The request content-type is not a multipart/form-data");
So I switched my method from PUT to POST.

Rebuild HTTP flow with incubated Java 10 HttpClient

I'm trying to rebuild the session setup to a web server by a Java HttpClient application. I have chosen the incubated HttpClient provided with Java 9 and Java 10.
With Chrome I captured this headers from a single request:
General
Request URL: https://<some_url>?user_id=1176&onlyDirectUserItems=true&onlyAssignedToUser=true&show=Unresolved&itemsFilter=0
Request Method: GET
Status Code: 302 Found

What can be seen the Response Header provides a URL (header-key: "location") which I need to grab and call next. But with my http client I fail with status-code 400 and get almost nothing
This is my code
url = "https://<some_url>?user_id=1176&onlyDirectUserItems=true&onlyAssignedToUser=true&show=Unresolved&itemsFilter=0";
HttpClient client = HttpClient.newBuilder()
.proxy(ProxySelector.of(new InetSocketAddress("<theProxy>", 8000)))
.cookieHandler(new CookieManager(null, CookiePolicy.ACCEPT_ALL))
.followRedirects(HttpClient.Redirect.SAME_PROTOCOL)
.build();
HttpRequest request = HttpRequest.newBuilder()
.header("User-Agent", "Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:60.0) Gecko/20100101 Firefox/60.0")
.header("Upgrade-Insecure-Requests", "1")
// .header("Host", "<host>")
.header("Connection", "keep-alive")
.header("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8")
.header("Accept-Language", "de-DE,de;q=0.9,en-US;q=0.8,en;q=0.7")
.header("Accept-Encoding", "gzip, deflate, br")
.uri(new URI(url))
.build();
HttpResponse<String> response = client.send(request, HttpResponse.BodyHandler.asString());
HttpHeaders headers = response.headers();
Map<String, List<String>> headerMap= headers.map();
for (String key : headerMap.keySet()) {
System.out.println(">"+key+"<");
for (String value : headerMap.get(key)) {
System.out.println(" " + value);
}
}
System.out.println(response.statusCode());
System.out.println(response.body());
I have no clue what might be wrong and how to proceed to get this done. I hope someone can tell me what to ty next.
What I also do not understand: I had to remove the header "Host" - because I got the response: "Your browser sent a request that this server could not understand."
The very same header as can be found in the Chrome-listing

I could get it run with Apache HttpClient. I cannot tell what is wrong with the incubated HttpClient - but there is for sure a reason that it is not a fully integrated part of the Java 9/10 delivery

Getting 500 error from HttpClient, works in browser

I'm using Apache HttpClient to try to submit some post data to a server. Unfortunately, I don't have access to the server to get any log information so that won't be possible.
If I go through this process with Firefox, it works fine. (I do get a 302 warning on this particular page)
I have matched the Request headers of both Firefox and my program.
Firefox Request Headers:
Host: server ip
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Referer: https://server ip/
Content-Type: application/x-www-form-urlencoded
Content-Length: 407
Cookie: sessionId=blahblah
Connection: keep-alive
Upgrade-Insecure-Requests: 1
My Programs Request Headers shown from context.getRequest().getAllHeaders();
Host: server ip
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Referer: https://server ip/
Content-Type: application/x-www-form-urlencoded
Connection: keep-alive
Upgrade-Insecure-Requests: 1
Content-Length: 406
Cookie: sessionId=blahblah
I have matched the body of the request by comparing the output of EntityUtils.toString(httpPost.getEntity(), "UTF-8"); and the built in tool for Firefox's tool to look at the request body, and they match almost character for character. (Just a slight difference in the session id which is expected as it's not using the same session.)
I'm not sure what else to check. What could be causing the server to behave differently between the Browser and the program?
Below is my code for the POST request.
HttpPost httpPost = new HttpPost("https://" + getIp() + "");
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("FTPUsername", "blah"));
params.add(new BasicNameValuePair("FTPPassword", "blah"));
params.add(new BasicNameValuePair("FormButtonSubmit", "OK"));
httpPost.setEntity(new UrlEncodedFormEntity(params));
httpPost.setHeader("Host", ip);
httpPost.setHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0");
httpPost.setHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
httpPost.setHeader("Accept-Language", "en-US,en;q=0.5");
httpPost.setHeader("Accept-Encoding", "gzip, deflate, br");
httpPost.setHeader("Referer", referer);
httpPost.setHeader("Content-Type", "application/x-www-form-urlencoded");
httpPost.setHeader("Connection", "keep-alive");
httpPost.setHeader("Upgrade-Insecure-Requests", "1");
//Response
HttpResponse response = getHttpClient().execute(httpPost, LoginRequest.context);
int statusCode = response.getStatusLine().getStatusCode();
httpPost.releaseConnection();
I realize this could probably be many things since 500 is a server error, but it's got to be something I'm submitting wrong or I'm missing something as it works perfectly in the browser.

302 "warning" is actually a redirect. HTTP Client does do redirect automatically, you must flag the RedirectStrategy, For HttpClient 4.3:
HttpClient instance = HttpClientBuilder.create()
.setRedirectStrategy(new LaxRedirectStrategy()).build();
see examples in answer and w3 docs:
If the 302 status code is received in response to a request other than
GET or HEAD, the user agent MUST NOT automatically redirect the
request unless it can be confirmed by the user

Do you work with Windows machine? or Linux machine?
If you use a windows machine, have you tried working with WAMP server for Linux use LAMP server, so if you install it, you won't get those errors, that's how I fixed my error. Once if you install these two servers, change the port number in skype by logging into Skype and change the port number or uninstall your skype. It should work.

Build HttpServletRequest from predefined data

For testing I want to build HttpServletRequest object from some predefined data, something like:
GET / HTTP/1.1
User-Agent: Opera/9.80 (Windows NT 6.1; WOW64; U; en) Presto/2.10.289 Version/
12.01
Host: www.foo.com
Accept: text/html, application/xml;q=0.9, application/xhtml+xml, image/png,
image/webp, image/jpeg, image/gif, image/x-xbitmap;q=0.1
Accept-Language: ru-RU,ru;q=0.9,en;q=0.8
Accept-Encoding: gzip, deflate
Pragma: no-cache
Cache-Control: no-cache
Connection: Keep-Alive
And also setup url and client address. Is there some simple way to do it?

Kirill! I think the best way in your case is using Mockito framework.
For example, you can make mock of HttpServletRequest interface. And use:
HttpServletRequest httpRequest = Mockito.mock(HttpServletRequest.class);
Mockito.when(httpRequest.getHeader("Host")).thenReturn("http://www.foo.com");
Mockito.when(httpRequest.getHeader("Referer")).thenReturn("blalba");
Mockito.when(httpRequest.getHeader("User-Agent")).thenReturn("Opera");
Mockito.when(httpRequest.getRemoteAddr()).thenReturn("127.0.0.1");

You can write a parse to read the predefined data and use HttpClient to send requests as per your requirements.

how to test gwt requestbuilder with junit in gwttestcase?

My GWT app contains data which must be read out from xml-files which are on the client side.
For this i am using RequestBuilder.
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET,GWT.getHostPageBaseURL()+"myFile.xml");
try{
builder.sendRequest(null, new RequestCallback() {
#Override
public void onResponseReceived(Request request,Response response) {
// read out data and put into to a list
}
});
.........
The data will be read out put it into an list and from this list the datas will be put into to the view.
How to test this?
When i try this in the GWTTestCase class with some assertEquals methods inside the onResponseReceived i get this error-message:
[WARN] 404 - GET /com.test.app.appName.JUnit/myFile.xml (192.168.2.102) 1466 bytes

What i am doing wrong?
Please help.

You should follow up with GWT Test code for RequestBuilder available in their source code. You can search as RequestBuilder test cases.
Also in your case you might be best served to just use mocking to avoid slowing down test cases.
