I was trying to run application in eclipse, it was running fine. I created jar using Maven install, and while running the jar I am getting the error "Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/context]

First time working with web apps and created a simple springboot rest api and it worked fine locally. Deployed the war to a tomcat server by copying the war file into the /webapps/ directory and restarted tomcat.
I checked if this was successful by opening the tomcat web application manager page and can see the app listed:
http://1xx.xxx.xxx.xxx:8080/manager/
When I click start to get it running the following error appears:
FAIL - Application at context path [/first_restapi] could not be started
I searched around and most answers suggest ensuring all pom file dependencies are included and to check the logs. I checked the logs on the tomcat server and the following error stuck out:
Exception sending context initialized event to listener instance of class
[org.springframework.web.context.ContextLoaderListener]
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem:
Unable to locate Spring NamespaceHandler for XML schema namespace
[http://www.springframework.org/schema/security]
Offending resource: ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml]
I did not include a servlet-context.xml file as the tutorial did not show that. But I added it anyway and still got the same error. Can anyone help with this issue?

You have a dependency problem. For each XML namespace that you (effectively) use in your configuration file, you need the appropriate NamespaceHandler. So in your case, to use the:
beans or util namespace you need spring-beans.jar,
context or task namespace you need spring-context.jar,
mvc namespace you need spring-webmvc.jar,
security namespace you need spring-security-config.jar.
You certainly don't have the last one dependency.
I am trying to integrate spring and Apache solr. For that i am trying NamespaceHandler http://www.springframework.org/schema/data/solr. But this giving me the following error.
Can any please help me.

This is leading to an error
Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/data/solr]Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml]
Thanx in advance for any help..
If this is a new project, you should start from Spring Boot and add Spring Data Solr into it. There are sample projects of how to do it. You can also check a real project using Spring Boot, and Spring Data Solr for auto-complete.
I need to integrate Spring with CXF version 3.0. CXF libraries are in the classpath. I am getting the error "Unable to locate Spring NamespaceHandler for XML schema namespace [http://cxf.apache.org/jaxws]" when trying to access the web service. What could be the wrong here ? By any chance Schema url got changed?

Did you put the cxf-rt-frontend-jaxws.jar into the class path?
The offline xml schema can be found there.

Here is the screen shot of my included jars
What i am doing wrong with the namespace ?
Thanks
I think the problem is your using spring-data-commons-core version 1.1 and spring-data-jpa version 1.2. Align the versions of these libraries.
Looking at a pom.xml file from one of my projects I see.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>1.2.0.RELEASE</version>
</dependency>
and it uses spring-data-commons-core-1.4.0.RELEASE.jar
If you switch the packaging of spring-data-jpa to pom, it should download the necessary dependencies, then switch it back to jar.
I'm using Spring+Drools in my Web Application.The following is the drools modules configuration

When I ran my application using this configuration in my junit project it worked, yet it came with the following problem when I startup my Web application. As a result, I couldnot find my kbase bean.

You see, I didn't put the drools-service-spring.xsd in my .xml file. So I'm quite stuck with it. Any suggestions?
