How to properly locate Spring Context property-placeholder?

I am attempting to implement an outdated open-source Properties File Manager (https://github.com/Confluex/Zuul/wiki) with a Mule Test Application in MuleSoft's Anypoint Studio platform. This appears to require the Spring Context Schema, but the project cannot locate it. It continually states there is no 'context:property-placeholder'. I feel a versioning error may be the problem. Here is my attempt:
<mule
xmlns="http://www.mulesoft.org/schema/mule/core"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:spring="http://www.springframework.org/schema/beans"

zuul-spring-client-1.5.1 zuul-spring-client-1.5.1.xsd">
<context:property-placeholder properties-ref="MuleMeetZuul" />
</mule>
Here is the error thrown:

Any advice would be much appreciated. Thanks.

If you are trying to use the Mule 3 implementation in a Mule 4 it will fail, and that should be expected. Mule 3 property placeholder providers where directly Spring property placeholder providers. Mule 4 uses a different way to implement them. <context:property-placeholder> doesn't exist in Mule 4. Its replacement <configuration-properties> will not work for this usage.
Instead you will have to use Mule SDK for Java to develop a custom configuration property provider by implementing the ConfigurationPropertiesProviderFactory interface in a factory class and extending the DefaultConfigurationPropertiesProvider class to implement the provider. In the provider you will need to use the Zuul library to implement the operations to get the keys and values.
Instructions are available in the documentation: https://docs.mulesoft.com/mule-runtime/4.3/custom-configuration-properties-provider

NoSuchBeanDefinitionException: No bean named 'FirstPage' is defined

I am very new to Spring Framework. I am using NetBeans for IDE. I followed couple of tutorials to learn it by myself. However, I am stuck in the middle and cannot proceed further. Let me breakdown my project here:
My project folder structure looks like this:
There are two classes; the major one MainApp.java contains following code:
package com.myprojects.spring;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class MainApp {
public static void main(String[] args) {
ApplicationContext context;
context = new ClassPathXmlApplicationContext("classpath*:beans.xml");
FirstPage obj;
obj = (FirstPage) context.getBean("firstPage");
obj.getMessage();
}
}
Second class file FirstPage.java looks like this:
package com.myprojects.spring;
public class FirstPage {
private String message;
public void setMessage(String message){
this.message = message;
}
public void getMessage(){
System.out.println("Your Message : " + message);
}
}
The beans.xml file looks like below:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.0.RELEASE.xsd
">
<bean id = "firstPage" class = "com.myprojects.spring.FirstPage">
<property name = "message" value = "Hello World!"/>
</bean>
</beans>
Now, the error I am getting is like below:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'firstPage' is defined
I know I have been doing some silly mistake here.
Thank you in Advance !

Almost similar problem have been discussed before. I think your program is unable to locate beans.xml.
Try doing this:
context = new ClassPathXmlApplicationContext("META-INF/beans.xml");
EDIT:
This new error XmlBeanDefinitionStoreException means that your schema is not valid. Try changing your schema as described in one of these answers:

Spring configuration XML schema: with or without version?
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<bean id = "firstPage" class = "com.myprojects.spring.FirstPage">
<property name = "message" value = "Hello World!"/>
</bean>
</beans>

According to the directory structure you posted it is very likely that src/main/resources is on your classpath. If you like to reference your spring context file beans.xml you have to specify it relative to the folders on your classpath. Hence you should try:
context = new ClassPathXmlApplicationContext("classpath:/META-INF/beans.xml");
Besides: the notation classpath*:beans.xml means you want to read in all context files having a name of beans.xml.

Put beans.xml to outside Meta-inf ,
or use new ClassPathXmlApplicationContext("META-INF/beans.xml");
And http://www.springframework.org/schema/beans/spring-beans-4.0.0.RELEASE.xsd
should change to
http://www.springframework.org/schema/beans/spring-beans-4.0.0.xsd , as spring's xsd filenames don't contain "RELEASE".
The xsd files are in org.springframework.beans.factory.xml package in spring-beans.jar, see if the xsd file is in that package.

Doing following two things solved my issue.
1) There was an incorrect beans.xml path. I changed that to context = new ClassPathXmlApplicationContext("META-INF/beans.xml");.
2) Also, there was an invalid xsi:schemaLocation attribute value. I changed that attribute's value to http://www.springframework.org/schema/beans/spring-beans-3.0.xsd.
Thank you all for your help.

Spring, XMLCOnfiguration: Without indicating annotation in xml file how it is working?

I am trying to write a spring program with using Annotation config in xml file, It is working without this configuration initiating also. I wrote method() in one file and and declared CLassPathXmlApplicationContext with Beans.xml file, I wrote a Student bean and applied the #Required annotation for setter methods, Please find the Bean configuration xml file below:
<?xml version = "1.0" encoding = "UTF-8"?>
<beans xmlns = "http://www.springframework.org/schema/beans"
xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"
xmlns:context = "http://www.springframework.org/schema/context"
xsi:schemaLocation = "http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:annotation-config/>
<!-- Definition for student bean -->
<bean id = "student" class = "com.tutorialspoint.Student">
<property name = "name" value = "Zara" />
<property name = "age" value = "11"/>
</bean>
</beans>
When i run this program with or without following Annotation indication in xml file, the code works fine, Please guide me the underlying reason for it.
<context:annotation-config/>

The #Required annotation applies to bean property setter methods and it indicates that the affected bean property must be populated in XML configuration file at configuration time.
Once <context:annotation-config/> is configured, you can start annotating your code to indicate that Spring should automatically wire values into properties, methods, and constructors. It does not means that some things will wrong without it when you using the #Required
In your xml, you have defined your properties, so the #Required will run well

Spring XML cannot find my Spring Java Configuration Class

So I have been using the 3.2.0.RELEASE Spring XML configurations for most of my beans but now I am faced with a unique situation where the Getters and Setters can't be used (bad legacy code - can't get around it).
As such, I want to use Spring #Configuration class and the XML to workaround this problem.
However, I am getting "Class Not Found" exception when it tries to read my #Configuration Class.
Caused by: java.lang.ClassNotFoundException: v1.inventory.item.myJavaConfig
My XML file which is failing looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="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:annotation-config/>
<bean class="v1.inventory.item.myJavaConfig"/>
</beans>
My #Configuration class looks like this:
package v1.inventory.item;
#Configuration
#ImportResource("classpath:v1/inventory/item/baseItemConfigs.xml")
public class myJavaConfig {
#Autowired
#Qualifier("parentItem")
Item baseItem;
#Bean
public Item realItem(){
Item modifiedBean = baseItem;
modifiedBean.setManufacturer("Fake Setter for Manufacturer");
modifiedBean.setDesigner("Fake Setter for Designer");
return modifiedBean;
}
}
I need this to be read by the ApplicationContext so I need to make sure these beans can be found. Is this a bug with Spring 3.2.0.RELEASE? Or my code?
For the record, I am pulling in the #Configuration last (parentItem is scanned first in XML).

I figured out the issue here.
It seems that maven/spring (not sure which) wasn't looking in my "resource" directory for the file. Only my "java" directory. When I moved my file into the "java" directory, Spring found the file just fine.
The tests which were passing in JUnit now pass using the Maven compiler (which was throwing the above error during the test phase)

Why does the context initialization fail for the Spring MVC tutorial section 4.6?

I have followed the following Spring MVC tutorial which works fine until I deploy step 4.6:
Spring MVC step by step tutorial
The Errors I get are:
SEVERE: Context initialization failed
org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 10 i

I don't know why they are showing it like that and honestly you shouldn't be looking at a super old tutorial like that, but the solution is to simply remove the <beans> in
