Spring schemaLocation fails when there is no internet connection
JavaXmlSpringXsdJava Problem Overview
I am using Spring and in application-context.xml
I have the following definitions:

When my internet connection is lost, I cannot run my application via tomcat or jetty.
It gives:

Any suggestions how to fix it?
Java Solutions
Solution 1 - Java
There is no need to use the classpath: protocol in your schemaLocation URL if the namespace is configured correctly and the XSD file is on your classpath.
Spring doc "Registering the handler and the schema" shows how it should be done.
In your case, the problem was probably that the spring-context jar on your classpath was not 2.1. That was why changing the protocol to classpath: and putting the specific 2.1 XSD in your classpath fixed the problem.
From what I've seen, there are 2 schemas defined for the main XSD contained in a spring-* jar. Once to resolve the schema URL with the version and once without it.
As an example see this part of the spring.schemas contents in spring-context-3.0.5.RELEASE.jar:
http\://www.springframework.org/schema/context/spring-context-2.5.xsd=org/springframework/context/config/spring-context-2.5.xsd
http\://www.springframework.org/schema/context/spring-context-3.0.xsd=org/springframework/context/config/spring-context-3.0.xsd
http\://www.springframework.org/schema/context/spring-context.xsd=org/springframework/context/config/spring-context-3.0.xsd
This means that (in xsi:schemaLocation)
http://www.springframework.org/schema/context/spring-context-2.5.xsd
will be validated against
org/springframework/context/config/spring-context-2.5.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-3.0.xsd
or
http://www.springframework.org/schema/context/spring-context.xsd
will be validated against
org/springframework/context/config/spring-context-3.0.xsd
in the classpath.
http://www.springframework.org/schema/context/spring-context-2.1.xsd
is not defined so Spring will look for it using the literal URL defined in schemaLocation.

is the key for working offline mode (no internet connection). Also i copied spring-context-2.1.xsd
near (same directory) the application-context.xml file

Something like this worked for me.
xsi:schemaLocation=
"http://www.springframework.org/schema/beans
classpath:org/springframework/beans/factory/xml/spring-beans-3.0.xsd
http://www.springframework.org/schema/context
classpath:org/springframework/beans/factory/xml/spring-context-3.0.xsd"
Solution 4 - Java
In case anyone arrives here via the same root I did - I hit this problem because I was building a single JAR with all dependencies, including Spring JARs. As a result the spring.schemas file in some of the META-INF directories of Spring JARs was overwritten.
I found suggested solutions here: https://stackoverflow.com/questions/11160534/how-to-create-spring-based-executable-jar-with-maven
Solution 5 - Java
Ran into a similar issue today. In my case, it was the shade plugin that was the culprit, in addition to springframework.org having an outage. The following snippet cleared things up:
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.schemas</resource>
</transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
<resource>META-INF/spring.handlers</resource>
</transformer>
HTH someone
Solution 6 - Java
You should check that the spring.handlers
and spring.schemas
files are on the classpath and have the right content.
This can be done with ClassLoader.getResource(..)
. You can run the method with a remote debugger in the runtime environment. The extensible XML authoring setup is described in the Spring Reference B.5. Registering the handler and the schema.
Normally, the files should be in the spring jar (springframework.jar/META-INF/) and on the classpath when Spring can be initiated.
Solution 7 - Java
Find class path
If you are using eclipse click on corresponding jar file. Goto ->META-INF-> open file spring.schemas
you will see the lines something like below.
copy after = and configure beans something like below.
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:util="http://www.springframework.org/schema/util" xmlns:rabbit="http://www.springframework.org/schema/rabbit" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/rabbit classpath:org/springframework/amqp/rabbit/config/spring-rabbit-1.1.xsd http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-3.1.xsd http://www.springframework.org/schema/context classpath:org/springframework/context/config/spring-context-3.1.xsd http://www.springframework.org/schema/util classpath:org/springframework/beans/factory/xml/spring-util-3.1.xsd">
Solution 8 - Java
You need to add schema locations to your bean definition, and then they can be found in classpath instead of fetched over the net. Given your formatting problems, I'm not 100% sure that you aren't doing this already.
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
<!-- empty: the beans we use are in the base class's context. -->
</beans>
Solution 9 - Java
The problem lies in the JAR files that you use in your application.
What I did, which worked, was to get inside the JARs for SPRING-CORE, SPRING-BEANS, SPRING-CONTEXT, SPRING-TX that match the version I am using. Within the META-INF folder, I concatenated all the spring.handlers and spring.schemas that come in those JARs.
I killed two birds with one stone, I solved the problem of the schemas so this also works correctly in offline mode.
P.S. I tried the maven plugin for SHADE and the transformers but that did not work.
Solution 10 - Java
We solved the problem doing this:
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setNamespaceAware(true);
factory.setValidating(false); // This avoid to search schema online
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaSource", "TransactionMessage_v1.0.xsd");
Please note that our application is a Java standalone offline app.
Solution 11 - Java
If you are using eclipse for your development , it helps if you install STS plugin for Eclipse [ from the marketPlace for the specific version of eclipse .
Now When you try to create a new configuration file in a folder(normally resources) inside the project , the options would have a "Spring Folder" and you can choose a "Spring Bean Definition File " option Spring > Spring Bean Configuation File .
With this option selected , when you follow steps , it asks you to select for namespaces and the specific versions :
And so the possibility of having a non-existent jar Or old version can be eliminated .
Would have posted images as well , but my reputation is pretty low.. :(
Solution 12 - Java
I would like to add some additional aspect of this discussion. In windows OS I have observed that when a jar file containing schema is stored in a directory whose path contains a space character, for instance like in the following example
"c:\Program Files\myApp\spring-beans-4.0.2.RELEASE.jar"
then specifying schema location URL in the following way is not sufficient when you are developing some standalone application that should work also offline
<beans
xsi:schemaLocation="
http://www.springframework.org/schema/beans org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
/>
I have learned that result of such schema location URL resolution is a file which has a path like the following
"c:\Program%20Files\myApp\spring-beans-4.0.2.RELEASE.jar"
When I started my application from some other directory which didn't contain space character on its path then schema location resolution worked fine. Maybe somebody faced similar problems? Nevertheless I discoverd that classpath protocol works fine in my case
<beans
xsi:schemaLocation="
http://www.springframework.org/schema/beans classpath:org/springframework/beans/factory/xml/spring-beans-2.0.xsd"
/>
Solution 13 - Java
I had this problem. For posterity, my exception was:
org.xml.sax.SAXParseException; lineNumber: 7; columnNumber: 117;
schema_reference.4: Failed to read schema document
'http://www.springframework.org/schema/beans/spring-beans-4.2.xsd'
I solved it when I realised the the version of spring-beans
specified in my Maven pom.xml
was 4.1.x
, thus meaning the specific .xsd
could not be found on the classpath.
This was masked for a long time because I normally am online, so I thought being offline had "broken" the build. But it really had nothing to do with it. Updating my pom.xml
to specify the correct version of spring-beans
, namely 4.2.x
, fixed it.
Solution 14 - Java
I had the same problem when I'm using spring-context version 4.0.6 and spring-security version 4.1.0.
When changing spring-security version to 4.0.4 (because 4.0.6 of spring-security not available) in my pom and security xml-->schemaLocation, it gets compiled without internet.
So that mean you can also solve this by:
-
changing spring-security to a older or same version than spring-context.
-
changing spring-context to a newer or same version than spring-security.
(any way spring-context to be newer or same version to spring-security)
Solution 15 - Java
I had ran into this similar problem as well. In my case, my resolution is quite different. Here's my spring context xml file:
...
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
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
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
...
I'm not specifying any xsd version as I want spring to use the latest xsd version inside spring dependencies. The spring version my application used was spring-beans-4.3.1.RELEASE.jar:4.3.1.RELEASE and when I assembly my application into jar, all spring dependencies exist in my classpath. However, I received following error during startup of my spring application context:
org.xml.sax.SAXParseException: schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/beans/spring-beans.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.
After some hard time troubleshooting, I found the issue is due to the index.list inside the META-INF folder of my jar file. With index.list file, spring namespace handlers cannot be located to parse the spring application context xml correctly. You can read more about this spring issue SPR-5705
By removing indexing from my maven-jar-plugin, I manage to resolve the issue. Hope this will save some times for people having the same problem.
Solution 16 - Java
Just make sure the relevant spring jar file are in your runtime classpath. In my case this we were missing spring-tx-4.3.4.RELEASE.jar from runtime classpath. After adding this jar, the issue was resolved.
Solution 17 - Java
If there is no internet connection in your platform and you use Eclipse, follow these steps (it solves my problem)
- Find the exact xsd files (You can unzip these files from their jars. For example, spring-beans-x.y.xsd in spring-beans-x.y.z.RELEASE.jar)
- Add these xsd files to Eclipse XML Catalog. (Preferences->XML->XML Catalog, Add files)
- Add these files location to configuration file. (Be careful, write the exact version of file)
Example:
> xsi:schemaLocation=" http://www.springframework.org/schema/beans > http://www.springframework.org/schema/beans/spring-beans-x.y.xsd "
Solution 18 - Java
Remove jars you added recently in the web-inf ->lib. for example jstl jars.
