VALIDATION PROBLEMS WERE FOUND error while trying to deploy war on weblogic 12c

Question

I'm trying to deploy maven project on weblogic 12c. Project is configured in spring 4, (Java 1.8). Below is my WebLogic.xml

<?xml version="1.0" encoding="UTF-8"?>

<weblogic-web-app xmlns="http://xmlns.oracle.com/weblogic/weblogic-web-app" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd http://xmlns.oracle.com/weblogic/weblogic-web-app http://xmlns.oracle.com/weblogic/weblogic-web-app/1.0/weblogic-web-app.xsd">
<jsp-descriptor>
<keepgenerated>true</keepgenerated>
<debug>true</debug>
</jsp-descriptor>
<context-root>/FileCompare</context-root>
<fast-swap>
<enabled>false</enabled>
</fast-swap>
</weblogic-web-app>

Below is my web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">
  <display-name>FileCompare</display-name>
  <welcome-file-list>
    <welcome-file>login.jsp</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

The location of these two files are under WEB-INF. I'm successfully able to deploy this on apache tomcat8. But getting below error while trying to deploy war on weblogic 12c

Answer 1

I have deleted entire blow lines and after that application worked with some warning.

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1">

Answer 2

<web-app> has the wrong xml namespace. Try using xmlns="http://java.sun.com/xml/ns/javaee" instead.
