Spring XSD's access error

Question

I'm trying to run a system left by an ex-employee here in my job, but I'm having problems to do it.

If the XSD runs by remote access:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:tx="http://www.springframework.org/schema/tx"
    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-3.0.xsd
                           http://www.springframework.org/schema/aop 
                           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
                           http://www.springframework.org/schema/tx
                           http://www.springframework.org/schema/tx/spring-tx.xsd">

It gives an not found exception:

Failed to read schema document 'http://www.springframework.org/schema/context/spring-context-3.0.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>.

And if the XSD runs by local access:

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
           classpath:org/springframework/beans/factory/xml/spring-beans-3.0.xsd
           http://www.springframework.org/schema/tx
           classpath:org/springframework/transaction/config/spring-tx-3.0.xsd
           http://www.springframework.org/schema/context  
           classpath:org/springframework/context/config/spring-context-3.0.xsd
           http://www.springframework.org/schema/tool
           classpath:org/springframework/beans/factory/xml/spring-tool-3.0.xsd">

It gives this exception:

C:\Users\claudiomazur>java -jar c:\temp\fin\c.jar  
0 [AWT-EventQueue-0] INFO support.ClassPathXmlApplicationContext  - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@4fa52fdf: startup date [Thu Sep 06

        at org.springframework.beans.factory.parsing.FailFastProblemReporter.error(FailFastProblemReporter.java:68) 

Some idea to solve this problem?

Big hug!!

Answer 1

The Spring XDSs are defined and shipped with the Spring jars! For Example the spring-context.jar contains the spring-context-3.0.xsd. (see spring-context.jar/META-INF/spring.schema)

So check that you have this jar in your project.

So what you called "remote" is not really remote! And I have never see what you called "local access", so I would try to check why the "remote" (that is not remote) stuff works for all xsds but the spring-context.

---

If it is a desktop program and you use a single jar that contains all the other exploded jars, then you need a to take care that the content of the single spring.handlers and spring.schames files from the different spring-xxx.jar is COMBINED in (two) "hunge" files. So that in the end this (two) files contains all the schema names and handler names.

Answer 2

Its true that the SPRING XSD's are shipped along with the jars.

The information where these XSD's are stored :

1. Lets say in the XML file, we have used beans namespace and we need to look into

   xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans.xsd
   

2. Please check the file "spring-schemas" spring-beans-4.0.1.RELEASE.jar in META-INF folder. Sample context from this file should be:

   http\://www.springframework.org/schema/beans/spring-beans-4.0.xsd 
   =org/springframework/beans/factory/xml/spring-beans-4.0.xsd
   
   http\://www.springframework.org/schema/beans/spring-beans.xsd 
   =org/springframework/beans/factory/xml/spring-beans-4.0.xsd
   

3. Thus

        http\://www.springframework.org/schema/beans/spring-beans.xsd  is mapped to      
        org/springframework/beans/factory/xml/spring-beans-4.0.xsd
   

   in your jar

Answer 3

try run wget http://www.springframework.org/schema/context/spring-context-3.0.xsd.

should be something like: wget http://www.springframework.org/schema/context/spring-context-3.0.xsd

If you have a problem with getting xsd schema, it makes difficult to work with xml files inherited this schema.

In second case you simply don't have in classpath any of spring-*-3.0.xsd files.
