URI is not registered (Settings | Languages & Frameworks | Schemas and DTDs) in applicationContext.xml
XmlIntellij IdeaXml Problem Overview
I created an application Context.xml at the WEB-INF/classes directory.
and I have added the <!DOCTYPE> in the xml. I am getting the below error:
> URI is not registered (Settings | Languages & Frameworks | Schemas and DTDs)
You can see the snapshot below:
The xml is below:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> // -> there comes the issue
<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.xsd">
</beans>

Solution 1 - Xml
You can easy solve it by: Fetch external resource.

Click the light(your is red) -> Fetch external resource.
Solution 2 - Xml
This did the work:
Alt+Enter -> Fetch external resource
Solution 3 - Xml
I'm assuming this is in IntelliJ IDEA or some other JetBrains tool. If you place the cursor over the URL (or select it), you should see a red bulb on the left border of the window. That red bulb, when clicked, will give you some options to correct any errors. One of the options should be to download the DTD (Fetch external resource). Do that and the error should go away.
Solution 4 - Xml
If you select and hit ALT+ENTER i.e. More Actions... then following options would be displayed:
1. Add xsi schema location for external resource
2. Fetch external resource <- my preferred way
3. Ignore external resource
4. Manually setup external resource
Most of the time you would either select option no. 2 or 3 to get rid of this error.
Solution 5 - Xml
For me Build > Clean Project worked.
Solution 6 - Xml
Times change and Apache simply does not support that 1.xx version of log4j anymore. That XML really is not there on that address.
log4j is dead. Long live log4j2!
Look here:
https://logging.apache.org/log4j/2.x/manual/migration.html.
New configuration language is shorter and more convenient:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">
<PatternLayout pattern="%d %-5p [%t] %C{2} (%F:%L) - %m%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="org.apache.log4j.xml" level="info"/>
<Root level="debug">
<AppenderRef ref="STDOUT"/>
</Root>
</Loggers>
</Configuration>
If you feel you must use the old version, you should download the old XML that lived at the old address, put it on your server and use the new address.
Solution 7 - Xml
In my case, I was opening XML resource files from debug build variant while my Android Studio had beta build variant selected.
I switched to the debug build variant (to which the XML file belonged) and voila! errors gone.
Solution 8 - Xml
If you're in a JetBrains context, and Fetch external resource does not work, try File -> Invalidate Caches. Equivalent to clean project in eclipse, as mentioned in other answers.
Solution 9 - Xml
If "fetch" does not help, it means You have created this xml-file as empty file with .xml extention and filled config manually. Now delete it and recreate it propperly as "Spring config" file from template.
Solution 10 - Xml
Clean project worked for me. go to Build then click clean project.
