Keep Coding

Returning to jetty-maven-plugin I've trouble to set buffers size.
My use-case imply file upload (usual size is ~700Ko).
Because the upload is too big for jetty-maven-plugin default configuration I get Http response with error status code 413 (request too large)
I tryied using plugin configuration :
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${jetty-maven.version}</version>
<configuration>
<scanIntervalSeconds>3</scanIntervalSeconds>
<connectors>
<connector implementation="org.eclipse.jetty.server.nio.SelectChannelConnector">
<port>8080</port>
<maxIdleTime>60000</maxIdleTime>
<requestHeaderSize>8192</requestHeaderSize>
<requestBufferSize>2097152</requestBufferSize>
</connector>
</connectors>
</configuration>
</plugin>
Then I tried to use jetty-maven-plugin with a jetty.xml file
<plugin>
<groupId>org.mortbay.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>${jetty-maven.version}</version>
<configuration>
<scanIntervalSeconds>3</scanIntervalSeconds>
<jettyConfig>${basedir}/src/main/config/jetty/jetty.xml</jettyConfig>
</configuration>
</plugin>
The jetty.xml is below:
<?xml version="1.0"?>
<!DOCTYPE Configure PUBLIC "-//Mort Bay Consulting//DTD Configure//EN" "http://jetty.mortbay.org/configure.dtd">
<Configure id="Server" class="org.eclipse.jetty.server.Server">
<Call name="addConnector">
<Arg>
<New class="org.eclipse.jetty.server.nio.SelectChannelConnector">
<Set name="port"><SystemProperty name="jetty.port" default="8080"/></Set>
<Set name="requestHeaderSize">8192</Set>
<Set name="requestBufferSize">2097152</Set>
</New>
</Arg>
</Call>
</Configure>
Nothing works.
Could someone hand me the correct configuration please?

I'm not sure whether this fixes the problem in your use case, but you could try adding the following to your <configuration> section of the maven-jetty-plugin:
<systemProperties>
<systemProperty>
<name>org.eclipse.jetty.server.Request.maxFormContentSize</name>
<value>-1</value> <!-- or any other value -1 is for max -->
</systemProperty>
<systemProperties>
as mentioned by jesse mcconnell the property was renamed in jetty 7/8 to org.eclipse.jetty.server.Request.maxFormContentSize.
For jetty 6 for me org.mortbay.jetty.Request.maxFormContentSize is working.

change your pom as per this and add this two xml file into your project. I hope, it will work for you.
<plugin>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-maven-plugin</artifactId>
<version>9.2.11.v20150529</version>
<configuration>
<contextPath>/random-api</contextPath>
<scanIntervalSeconds>5</scanIntervalSeconds>
<jettyXml>jetty.xml,jetty-http.xml</jettyXml>
</configuration>
</plugin>

After a pause (lunch) I grabed the code of the web-app I was supposed to test.
There was a redundant limitation into its "internal" configuration (use an upload agent with it's own size limit).
In fact the two configuration proposed for jetty are working (now that web-app doesn't have any redundant limitation)
