"Unable to locate Spring NamespaceHandler for XML schema namespace" happening only in Executable jar

Question

I found several question with similar topic Context initialization failed org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 2 in XML document from ServletContext resource [/WEB-INF/App-servlet.xml] is invalid; nested exception is org.xml.sax.SAXParseException; systemId: http://www.springframework.org/schema/beans/spring-beans-4.2.xsd; lineNumber: 2; columnNumber: 18; s4s-elt-character: Non-whitespace characters are not allowed in schema elements other than 'xs:appinfo' and 'xs:documentation'..

I tried to applied the suggestions I have read but I keep getting same error.

Moreover, there is a specific thing to my case which I have not found around: the application below works perfectly in Eclipse. The error only happens in executable jar. I mean, I righ click on App.java and run it approperly. Nevertheless, if I export as Runnable Jar File and start it with java -jar I get the error showed below.

Static main method:

import org.apache.catalina.startup.Tomcat;
import javax.servlet.ServletException;
import org.apache.catalina.Context;
import org.apache.catalina.LifecycleException;
import org.apache.catalina.Wrapper;


public class App6 {

       public static void main(String[] args) throws ServletException, LifecycleException {

              Tomcat tomcat = new Tomcat();
              tomcat.setPort(8080);
              tomcat.setBaseDir(".");

              Context appContext = tomcat.addWebapp(tomcat.getHost(), "","C:\\STS\\wsRestTemplate\\AuthFileUpload\\target\\classes");

              Wrapper jspServlet = appContext.createWrapper();
              jspServlet.setName("jsp");            jspServlet.setServletClass("org.apache.jasper.servlet.JspServlet");

              jspServlet.addInitParameter("fork", "false");
              jspServlet.addInitParameter("xpoweredBy", "false");
              jspServlet.setLoadOnStartup(2);
              appContext.addChild(jspServlet);
              appContext.addServletMapping("*.jsp", "jsp");                

              tomcat.start();
              tomcat.getServer().await();
       }
}

App-servlet.xml (note that spring-beans-4.2.xsd and spring-context-4.2.xsd has the exact version in POM - some forum suggested it as possible error):

The problem most likely is in the packaging process, multiple spring dependencies have different META-INF/spring.schemas files that override each other. Hence, the final jar has a messed up spring.schemas file.

To fix this problem you can add the following configuration so that the contents of the .schema files are in proper format.

<configuration> <transformers> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.handlers</resource> </transformer> <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer"> <resource>META-INF/spring.schemas</resource> </transformer> </transformers> </configuration>

I followed your sggestion and now I am getting a new error "Unable to compile class for JSP". I have been struggling for the last 8 days to get an executable jar with Tomcat embedded. Certainly the process is with packaging process but I can't figure out what I am doing wrong. I can make the application run correctly if I do it inside of eclipse but I need to reach an executable jar with Tomcat or give up from embedded approach and come back to deploy to a server and, I am sure all my tentatives would work if I export as an EAR to Websphere or WAR to Tomcat server and forget embedded idea — Jim C, Mar 07 '16 at 21:28
