Java: Spring: XML conflict while reading spring context.xml Duplicate definition for: 'identType'

Any advice or help is greatly appreciated.

There are many links, but no clear solution. I wonder how Spring projects interact with PLSQL procedures that return XMLType output. you need XMLParser, and then we all get this error when used with Spring. Does anyone have any recommendations?

I have a Maven Spring application (mvc / Rest) that works well, and I added the following dependencies to interact with PLSQL procedures,

<dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.2.0.4</version> </dependency> <dependency> <groupId>com.oracle</groupId> <artifactId>xdb6</artifactId> <version>11.2.0.4</version> </dependency> <dependency> <groupId>com.xmlparserv2</groupId> <artifactId>xmlparserv2</artifactId> <version>11.1.1</version> </dependency>

After enabling xdb6 and xmlparserv2 I get the following error when starting the Spring application (when starting the server)

Suppose that I delete Line16 and its links, then the same error occurs on another line, for example, line 13

More error stack trace:

Update 1

Based on the answer, he says a quick solution is available,

To override the changes made using xmlparserv2.jar, add the following JVM properties to the startup arguments of your application server. The logic java.xml.parsers.FactoryFinder will first check the environment variables.

 -Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl -Djavax.xml.transform.TransformerFactory=com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl

This is not recommended, as clearly indicated in the link https://community.oracle.com/thread/1080787

Here's another solution mentioned (related to hibernation but similar): Using an Oracle XMLType column in hibernation

In the maven Spring project, override the xmlparserv2.jar parameters by creating the following files in the% PROJECT_HOME% / src / main / resources directory:

 %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.DocumentBuilderFactory (which defines com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl as the default) %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.parsers.SAXParserFactory (which defines com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl as the default) %PROJECT_HOME%/src/main/resources/META-INF/services/javax.xml.transform.TransformerFactory (which defines com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl as the default)

I don’t understand this.

How to transfer these files to the specified directory? and is this a recommended solution?

Update 2

I tried adding the VM argument -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl and it works.

However, the search for an alternative and more suitable solution. This is just a workaround. When an application is deployed to a server using Jenkins, it is impractical to set these VM argument parameters associated with the XML parser.

Update 3

@ Ying Roberts responded to fix the problem. I cleaned up context.xml to consistently use the version number for xsd.

The schemaLocation scheme is a mixture of version versions ( spring-beans-3.2.xsd ) and unversioned ( spring-tx.xsd ) schemes. You should use one style or the other in series, and not mix them. I suspect that what is happening here is that you are explicitly referencing version 3.2 of spring - beans, but one of your unversioned schemas imports another version of the same schema, resulting in two conflicting definitions of beans:identifiedType .

This article is quite old, but in any case, I came across this today and found a reason and another solution. It turns out that when you add the jazbc oracle driver dependency through maven using the Oracle maven repo, it transits other libraries that cause this problem when parsing XML. I just ruled out transitive dependencies for the oracle driver, and everything works fine. I do not think that these additional libraries are necessary at all at runtime.

If you have this in your pom:

 <dependency> <groupId>com.oracle.jdbc</groupId> <artifactId>ojdbc7</artifactId> <version>12.1.0.2</version> </dependency>

This is a dependency tree:

  • ojdbc7: 12.1.0.2
    • xdb6: 12.1.0.2
    • orai18n: 12.1.0.2
    • xmlparserv2: 12.1.0.2 <- Culprit
    • oraclepki: 12.1.0.2
    • osdt_cert: 12.1.0.2
    • osdt_core: 12.1.0.2

Thus, you can exclude such an abusive library:

 <dependency> <groupId>com.oracle.jdbc</groupId> <artifactId>ojdbc7</artifactId> <version>12.1.0.2</version> <exclusions> <exclusion> <artifactId>xmlparserv2</artifactId> <groupId>com.oracle.jdbc</groupId> </exclusion> </exclusions> </dependency>

I actually ruled out all the transitive dependencies, and everything seems to be working fine. I am not sure if they are really used. I don’t think so, because the manual way to enable the jdbc library is to simply load the ojdbc banner.

Here is your decision.

 -Djavax.xml.parsers.DocumentBuilderFactory=com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl`
