We Keep Coding

upgrading Apache Camel 2 to 3, where did Main.setApplicationContextUri() method go?

I have an old codebase that uses camel 2.something. We have to upgrade to camel 3.14 for Nexus-flagged security issues. I'm going through the Upgrade Camel 2 to 3 docs. I see that Main moved packages, which I did, but now I'm getting an error that Main.setApplicationContextUri("camel-context.xml") is no longer a method on Main. I can't find it, nor a replacement in the upgrade docs.
What am I missing?
Also, if there's a way to do a simple camel config via beans and annotations instead of xml, I'd love a pointer to that. I'm also running into an issue parsing the camel-context.xml, so if I can get rid of that whole mess, I'd love to.
We are using Java 8 so I think the latest that works with that is Camel 3.14.6 so that's what I'm trying.
Here's our camel-context.xml:

Edit: Just found this. Are we supposed to convert camel-context.xml to application.properties? We also have an app-context.xml for basic Spring configuration, and there's a reference to the camel-context.xml there. I wonder if we replace camel-context.xml with application.properties, what to do with this reference? Just remove it, or change it?

primary attribute not allowed inside bean tag

I have tried to set the default validation message file to messages.properties file. It worked. However, for some reason the primary attribute inside validator bean is marked red in the applicationContext.xml file.
The error message, "Attribute primary is not allowed here".
I have tried to find the reason of this in many resources and cross-checked many possibilities, but everything seems fine with my configuration.
I use Intellij Idea, Spring version - 3.2.17 RELEASE, Hibernate version - 3.6.10.Final.
Can anyone explain the reason ?
applicationContext.xml -

Spring MVC is not recognizing mvc:resource in config file

Update :Now Working properly. Kindly follow the comments.
This is my Spring configuration file:

All jars are included in this project, and the configuration file is shown above. I get errors for this part:

can you try below configuration that is copied from GIT - spring-mvc-showcase

change to spring-mvc.xsd to spring-mvc-3.0.xsd .Similarly change at all the remaining places too.

Cannot resolve property `paramName` in Spring MVC

I need to set Spring MVC interseptors to catch url parameter language and accordingly get data from .properties file. Getting error Cannot resolve propertyparamName when configuring context in servlet-config.xml:

I think you meant to use org.springframework.web.servlet.i18n.LocaleChangeInterceptor rather than SessionLocaleResolver.
<bean class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
<property name="paramName" value="language"/>
</bean>
This class is a HandlerInterceptor and does have a paramName property.
SessionLocaleResolver, on the other hand, is not.

Not sure what you expect but SessionLocaleResolver doesn't have such a param. Maybe you meant locale?

no declaration can be found for element 'mvc:annotation-driven'

I have the requirement of returning JSON/XML data from my controller.From what i found,I needed #ResponseBody in my method and for that I need <mvc:annotation-driven> enabled. I have tried all sorts of RnD but am still stuck! :(
Apparently my problem lies in my servlet.xml file (the schema isnt getting validated!)
I am using Spring 3.1.1 & have explicitly put in spring-mvc-3.1.1.jar in my classpath.
Here's my servlet-context file sample-servlet.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<context:component-scan base-package="com.sample.controller"/>
<mvc:annotation-driven/>
<!--Use JAXB OXM marshaller to marshall/unmarshall following class-->
<bean class="org.springframework.web.servlet.view.BeanNameViewResolver" />
<bean id="xmlViewer"
class="org.springframework.web.servlet.view.xml.MarshallingView">
<constructor-arg>
<bean class="org.springframework.oxm.jaxb.Jaxb2Marshaller">
<property name="classesToBeBound">
<list>
<value>com.sample.model.SampleClass</value>
</list>
</property>
</bean>
</constructor-arg>
</bean>
<bean class="org.springframework.web.servlet.view.ContentNegotiatingViewResolver">
<property name="viewResolvers">
<list>
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</list>
</property>
</bean>
My controller class looks like this :
#Controller
public class XmlController {
#RequestMapping(value="/getXml",method = RequestMethod.POST)
public #ResponseBody AssociateDetail getXml(){
System.out.println("inside xml controller.....");
AssociateDetail assoBean=null;
try{
AssociateService add=new AssociateService();
assoBean=add.selectAssociateBean();
}catch(Exception e){
e.printStackTrace();
}
return assoBean;
}
}
Now the problem is <mvc:annotation-driven /> gives error:
cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'mvc:annotation-driven'.
And I have tried all the workarounds suggested on this site and beyond. Have updated my schema namespaces, using Spring 3.1.1 and #ResponseBody.

As the error suggests there's something wrong with the schema declaration. You do not have the xsd s declared.
Use this instead.
