Hi,
I updated a product using a custom distribution from 4.2.6 to 4.2.7.
Because of this in the runtime the following versions has been changed:
* Pax Web: 7.2.10 to 7.2.11
* Jetty: from 9.4.18.v20190429 to 9.4.20.v20190813
There is a bundle that contains a HTTP servlet for a fie upload.
The POST request is handled by a method that takes the
HttpServletRequest "request" and the HttpServletResponse "response".
At the beginning it calls:
final Collection<Part> parts = request.getParts();
After that it handles the parts.
This worked before but does not anymore.
An exception is raised.

I do not use the "MultiPartInputStreamParser" myself just call
"request.getParts()" in line 152 of the UploadServlet.java file.
I assume the Jetty bundle misses some import for that specific util.
But this does not seems to be the case...
karaf@root()> bundle:list -t 0 -l | grep jetty | grep server
192 (0x Active │ 30 │ 9.4.20.v20190813 │
mvn:org.eclipse.jetty/jetty-server/9.4.20.v20190813
202 (0x Active │ 30 │ 9.4.20.v20190813 │
mvn:org.eclipse.jetty.websocket/javax-websocket-server-impl/9.4.20.v20190813
203 (0x Active │ 30 │ 9.4.20.v20190813 │
mvn:org.eclipse.jetty.websocket/websocket-server/9.4.20.v20190813
The command "bundle:headers 192" shows:
Import-Package =
...
org.eclipse.jetty.util;version="[9.4.20,10)",
...
There is also only one util bundle (except the additional ajax one):
karaf@root()> bundle:list -t 0 -l | grep jetty | grep util
195 (0x Active │ 30 │ 9.4.20.v20190813 │
mvn:org.eclipse.jetty/jetty-util/9.4.20.v20190813
196 (0x Active │ 30 │ 9.4.20.v20190813 │
mvn:org.eclipse.jetty/jetty-util-ajax/9.4.20.v20190813
For me the following command shows the class is exported:
karaf@root()> bundle:classes 195 | grep MultiPartInputStreamParser
org/eclipse/jetty/util/MultiPartInputStreamParser$1.class | exported: true
org/eclipse/jetty/util/MultiPartInputStreamParser$Base64InputStream.class
| exported: true
org/eclipse/jetty/util/MultiPartInputStreamParser$MultiPart.class |
exported: true
org/eclipse/jetty/util/MultiPartInputStreamParser$NonCompliance.class
| exported: true
org/eclipse/jetty/util/MultiPartInputStreamParser.class | exported: true
What's wrong?
I assume it is not relevant, but let's not loose any information:
There is an init method of the http servlet implementation class that
looks like:
===
@Override
public void init() throws ServletException {
/*
* @MultipartConfig annotation for the class does not seem to work.
* So let's configure it programmatically.
*/
final MultipartConfigElement mc = new
MultipartConfigElement(tempDir.getAbsolutePath(), MAX_FILE_SIZE,
MAX_REQUEST_SIZE, FILE_SIZE_THRESHOLD);
for (final Entry<String, ? extends ServletRegistration> entry :
getServletContext().getServletRegistrations()
.entrySet()) {
final ServletRegistration reg = entry.getValue();
if (reg == null) {
continue;
}
if (reg instanceof ServletRegistration.Dynamic) {
final ServletRegistration.Dynamic regDyn =
(ServletRegistration.Dynamic) reg;
regDyn.setMultipartConfig(mc);
}
}
}
===
