Hi all, My name is Netta and I would appreciate your help with this:
I have the following jetty.xml file: Here is its content: <?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" " http://www.eclipse.org/jetty/configure.dtd";> <!-- =============================================================== --> <!-- Configure the Jetty Server --> <!-- --> <!-- Documentation of this file format can be found at: --> <!-- http://wiki.eclipse.org/Jetty/Reference/jetty.xml_syntax --> <!-- --> <!-- =============================================================== --> <Configure id="Server" class="org.eclipse.jetty.server.Server"> <!-- =========================================================== --> <!-- Server Thread Pool --> <!-- =========================================================== --> <Set name="ThreadPool"> <!-- Default queued blocking threadpool --> <New class="org.eclipse.jetty.util.thread.QueuedThreadPool"> <Set name="minThreads">10</Set> <Set name="maxThreads">10000</Set> <Set name="detailedDump">false</Set> </New> </Set> <!-- =========================================================== --> <!-- Set connectors --> <!-- =========================================================== --> <Call name="addConnector"> <Arg> <New class="org.eclipse.jetty.server.bio.SocketConnector"> <Set name="host"><SystemProperty name="jetty.host" /></Set> <Set name="port"><SystemProperty name="jetty.port" default="8983"/></Set> <Set name="maxIdleTime">50000</Set> <Set name="lowResourceMaxIdleTime">1500</Set> <Set name="statsOn">false</Set> <Set name="requestHeaderSize">1000000</Set> <Set name="requestBufferSize">1000000</Set> </New> </Arg> </Call> <!-- =========================================================== --> <!-- Set handler Collection Structure --> <!-- =========================================================== --> <Set name="handler"> <New id="Handlers" class="org.eclipse.jetty.server.handler.HandlerCollection"> <Set name="handlers"> <Array type="org.eclipse.jetty.server.Handler"> <Item> <New id="Contexts" class="org.eclipse.jetty.server.handler.ContextHandlerCollection"/> </Item> <Item> <New id="DefaultHandler" class="org.eclipse.jetty.server.handler.DefaultHandler"/> </Item> <Item> <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler"/> </Item> </Array> </Set> </New> </Set> <!-- =========================================================== --> <!-- extra options --> <!-- =========================================================== --> <Set name="stopAtShutdown">true</Set> <Set name="sendServerVersion">false</Set> <Set name="sendDateHeader">false</Set> <Set name="gracefulShutdown">1000</Set> <Set name="dumpAfterStart">false</Set> <Set name="dumpBeforeStop">false</Set> <Call name="addBean"> <Arg> <New id="DeploymentManager" class="org.eclipse.jetty.deploy.DeploymentManager"> <Set name="contexts"> <Ref id="Contexts" /> </Set> <Call name="setContextAttribute"> <Arg>org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern</Arg> <Arg>.*/servlet-api-[^/]*\.jar$</Arg> </Call> </New> </Arg> </Call> <Ref id="DeploymentManager"> <Call name="addAppProvider"> <Arg> <New class="org.eclipse.jetty.deploy.providers.ContextProvider"> <Set name="monitoredDirName"><SystemProperty name="jetty.home" default="."/>/contexts</Set> <Set name="scanInterval">0</Set> </New> </Arg> </Call> </Ref> </Configure> It worked until we decided to upgrade the jetty version from 8.1.10.v20130312 to 9.4.29.v20200521. Now the server fails to start. I'm trying to change it so it will a - work (i.e. fit the API changes that happen between the versions) b - will be as close to the original file as possible (since I don't know the consequences of changing one part or another, the impact on performance it will have, etc.) This is what I have so far (major changes are in bold): Here is the content: <?xml version="1.0"?> <!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN" " http://www.eclipse.org/jetty/configure_9_3.dtd";> <!-- =============================================================== --> <!-- Configure the Jetty Server --> <!-- --> <!-- Documentation of this file format can be found at: --> <!-- http://wiki.eclipse.org/Jetty/Reference/jetty.xml_syntax --> <!-- --> <!-- =============================================================== --> <Configure id="Server" class="org.eclipse.jetty.server.Server"> <!-- =========================================================== --> <!-- Server Thread Pool --> <!-- =========================================================== --> <!-- <Set name="ThreadPool">--> <!-- Default queued blocking threadpool --> <!-- <New class="org.eclipse.jetty.util.thread.QueuedThreadPool">--> There is no setThreadPool method in the new API <!-- <Set name="minThreads">10</Set>--> <!-- <Set name="maxThreads">10000</Set>--> <!-- <Set name="detailedDump">false</Set>--> <!-- </New>--> <!-- </Set>--> <!-- =========================================================== --> <!-- Set connectors --> <!-- =========================================================== --> <Call name="addConnector"> <Arg> <New class="org.eclipse.jetty.server.ServerConnector"> <Arg name="server"><Ref refid="Server" /></Arg> <Set name="host"><SystemProperty name="jetty.host" /></Set> <Set name="port"><SystemProperty name="jetty.port" default="8983"/></Set> <Set name="idleTimeout">50000</Set> <!-- <Set name="lowResourceMaxIdleTime">1500</Set>--> <!-- <Set name="statsOn">false</Set>--> Some fields are not available anymore <!-- <Set name="requestHeaderSize">1000000</Set>--> <!-- <Set name="requestBufferSize">1000000</Set>--> </New> </Arg> </Call> <!-- =========================================================== --> <!-- Set handler Collection Structure --> <!-- =========================================================== --> <Set name="handler"> <New id="Handlers" class="org.eclipse.jetty.server.handler.HandlerCollection"> <Set name="handlers"> <Array type="org.eclipse.jetty.server.Handler"> <Item> <New id="Contexts" class="org.eclipse.jetty.server.handler.ContextHandlerCollection"/> </Item> <Item> <New id="DefaultHandler" class="org.eclipse.jetty.server.handler.DefaultHandler"/> </Item> <Item> <New id="RequestLog" class="org.eclipse.jetty.server.handler.RequestLogHandler"/> </Item> </Array> </Set> </New> </Set> <!-- =========================================================== --> <!-- extra options --> <!-- =========================================================== --> <Set name="stopAtShutdown">true</Set> <!-- <Set name="sendServerVersion">false</Set>--> <!-- <Set name="sendDateHeader">false</Set>--> <Set name="stopTimeout">1000</Set> <Set name="dumpAfterStart">false</Set> <Set name="dumpBeforeStop">false</Set> <Call name="addBean"> <Arg> <New id="DeploymentManager" class="org.eclipse.jetty.deploy.DeploymentManager"> <Set name="contexts"> <Ref refid="Contexts" /> </Set> <Call name="setContextAttribute"> <Arg>org.eclipse.jetty.server.webapp.ContainerIncludeJarPattern</Arg> <Arg>.*/servlet-api-[^/]*\.jar$</Arg> </Call> </New> </Arg> </Call> <Ref refid="DeploymentManager"> <Call name="addAppProvider"> <Arg> <New class="org.eclipse.jetty.deploy.providers.ScanningAppProvider"> ContextProvider is not available anymore. I chose ScanningAppProvider because <Set name="monitoredDirName"><SystemProperty name="jetty.home" default="."/>/contexts</Set> it seems to have a similar interface (a similar behavior - monitoredDirName, scanInterval) <Set name="scanInterval">0</Set> </New> </Arg> </Call> </Ref> </Configure> I have a few questions: 1. The old API had a setThreadPool method for the server. The new one hasn't. Instead, it has a constructor that accept a ThreadPool as argument . My problem is that in the jetty.xml file there is no way to give the server an argument, since the configure element doesn't support the Arg element. What can I do? Is there a way to the "set" the server's ThreadPool in version 9.4.29.v20200521? Is there a way to define a server constructor with a ThreadPool argument? Can I set the ThreadPool fields somehow? 2. The ScanningAppProvider is causing problems. I get the following error when I try to start my application: No suitable constructor: <New class="org.eclipse.jetty.deploy.providers.ScanningAppProvider"><Set name="monitoredDirName"><SystemProperty name="jetty.home" default="."/>/contexts</Set><Set name="scanInterval">0</Set></New> on DeploymentManager@8383a14{STOPPED} java.lang.IllegalStateException: No suitable constructor: <New class="org.eclipse.jetty.deploy.providers.ScanningAppProvider"><Set name="monitoredDirName"><SystemProperty name="jetty.home" default="."/>/contexts</Set><Set name="scanInterval">0</Set></New> on DeploymentManager@8383a14{STOPPED} at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.newObj(XmlConfiguration.java:1036) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.itemValue(XmlConfiguration.java:1561) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.value(XmlConfiguration.java:1462) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.access$600(XmlConfiguration.java:416) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration$Args.<init>(XmlConfiguration.java:1720) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration$Args.<init>(XmlConfiguration.java:1707) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.call(XmlConfiguration.java:963) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:536) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.refObj(XmlConfiguration.java:1084) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:551) at org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:452) at org.eclipse.jetty.xml.XmlConfiguration.configure(XmlConfiguration.java:385) As far as I can tell, I used the correct xml structure, the correct names of the class and methods (at this part, when comparing to the previous version that worked, all I changed was the class name, from ContextProvider to ScanningAppProvider, so I don't understand why I get this error. I would appreciate any and all comments, suggestions and solutions. Best regards, Netta
