XML Validation Problems - A schema cannot contain two global components with the same

I'm not sure how to resolve this problem. I'm getting the following error in eclipse (STS 2.8.1.RELEASE) with my spring web project. My spring version is 3.1.0.RELEASE.

Error Description
--------------------------
The errors below were detected when validating the file "spring-context-3.0.xsd" via the file "applicationContext-jpa.xml". In most cases these errors can be detected by validating "spring-context-3.0.xsd" directly. However it is possible that errors will only occur when spring-context-3.0.xsd is validated in the context of applicationContext-jpa.xml.

Any help would be much appreciated! Thanks.

I'm having this same problem, exactly the same, and don't have any idea how to solve.
I'm using this same versions of Spring Framework and STS, but my web project was generated by Spring Roo 1.2.

I've thinking that the problem would be caused by Roo, but seems not.

If you look closely, you'll see a couple of references to Spring Roo (1.2) in the config as well. That is also how my headers were generated. I posted in this forum because I didn't think it was a problem specific to Roo.

The problem is that spring-jpa-1.0.xsd hardcoded the version of spring-context to 3.0. That is the cause of the problems. Looks like this issue was fixed a while ago: https://jira.springsource.org/browse/DATAJPA-160. Unfortunately the fix is not in spring-data-jpa-1.0.2.RELEASE

Thank you very much!

I've changed the version of spring-data-jpa to 1.1.0.BUILD-SNAPSHOT and all worked fine.

weird, I started having a problem like this when I installed cloud foundry plugin for eclipse, tried your solution, it did not solve my problem.


the file applicationContext.jpa is acusing these errors:

the application works, its just a pain in the ass the compilation error, it was right after I installed the cloud foundry plugin =/

http://www.springsource.org/spring-data/jpa shows the exactly configuration.

Like this:

Code:

---

<repository>
 <id>spring-milestone</id>
 <name>Spring Maven MILESTONE Repository</name>
 <url>http://repo.springsource.org/libs-milestone</url>
</repository>

<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-jpa</artifactId>
 <version>1.0.3.RELEASE</version>
</dependency>

---

or this:

Code:

---

<repository>
 <id>spring-snapshot</id>
 <name>Spring Maven SNAPSHOT Repository</name>
 <url>http://repo.springsource.org/libs-snapshot</url>
</repository>

<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-jpa</artifactId>
 <version>1.1.0.BUILD-SNAPSHOT</version>
</dependency>

I'm pretty new to this.

Therefore I'm looking for a step by step procedure to avoid the error.

There should be some easy way because this error appears always directly after:

web mvc setup

any help is appreciated

1- Open the file pom.xml located at root of your project.
2- Locate the tag <repositories> and the respective end tag
3- before the end tag, put

Code:

---

<repository>
 <id>spring-snapshot</id>
 <name>Spring Maven SNAPSHOT Repository</name>
 <url>http://repo.springsource.org/libs-snapshot</url>
</repository>

---

now you will have a new repository location in internet that your maven will search for artifacs!
4- Now you must update your artifact version, crtl+F (or command if you are in mac) and search for spring-data-jpa. You will find something like this:

Code:

---

<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-jpa</artifactId>
 <version>1.0.2.RELEASE</version>
</dependency>

---

5 - Replace the above with the right version like in :

Code:

---

<dependency>
 <groupId>org.springframework.data</groupId>
 <artifactId>spring-data-jpa</artifactId>
 <version>1.1.0.BUILD-SNAPSHOT</version>
</dependency>
