Hello everyone,
I tried to pass my web application (eclipse project) from maven 7 to
maven 9 version(9.3.7.v20160115).
I changed the necessary settings in the various files, but when starting
jetty with the eclipse jetty-maven-plugin launching the command jetty:run
I got the error when loading the WebAppContext file specified in
jetty-env.xml:
the error message is
-------------------------------
|java.lang.IllegalArgumentException: Object of class
'org.eclipse.jetty.maven.plugin.JettyWebAppContext' is not of type
'org.eclipse.jetty.webapp.WebAppContext'. Object Class and type Class
are from different loaders. in
file:/xx/WebApp/src/main/webapp/WEB-INF/jetty-env.xml at
org.eclipse.jetty.xml.XmlConfiguration$JettyXmlConfiguration.configure(XmlConfiguration.java:295)
at
org.eclipse.jetty.xml.XmlConfiguration.configure(XmlConfiguration.java:245)
at
org.eclipse.jetty.plus.webapp.EnvConfiguration.configure(EnvConfiguration.java:116)|
-------------------------------
Following the instructions for configuring JNDI connections with jetty i
specified jetty-env.xml as follow:
|<Configureid='wac'class="org.eclipse.jetty.webapp.WebAppContext"><Newid="resInspector"class="org.eclipse.jetty.plus.jndi.Resource"><Arg><Refrefid="wac"/></Arg><Arg>jdbc/xxx</Arg><Arg><Newclass="org.apache.commons.dbcp.BasicDataSource"><Setname="driverClassName">org.postgresql.Driver</Set><Setname="url">jdbc:postgresql://xx:5432/xx</Set><Setname="username">xx</Set><Setname="password">xx</Set><Setname="maxActive">100</Set><Setname="maxIdle">30</Set><Setname="maxWait">-1</Set><Setname="defaultAutoCommit">false</Set></New></Arg></New></Configure>|
any idea what is set wrong?
In the source code I see in line 292 of the class
org.eclipse.jetty.xml.XmlConfiguration in subclass JettyXmlConfiguration
the condition that an IllegalArgumentException is thrown, when the
condition oClass != null && !oClass.isInstance(obj) is fulfilled.
There are compared the two classes
org.eclipse.jetty.maven.plugin.JettyWebAppContext and
org.eclipse.jetty.webapp.WebAppContext. The former being a subclass of
the second one.
thanks for your suggestions
Markus
