问题描述
在部署包含spring-ws的战争时，我遇到此错误：
{"WFLYCTL0062: Composite operation Failed and was rolled back. Steps that Failed:" => {"Operatio
n step-2" => {"WFLYCTL0080: Failed services" => {"jboss.deployment.unit.\"FLUX-WSApp.war\".undertow-deploym
ent" => "org.springframework.beans.factory.BeanCreationException: Error creating bean
...
Caused by: org.xml.sax.SAXException: SAX2 driver class org.apache.xerces.parsers.SAXParser not found
java.lang.classNotFoundException: org.apache.xerces.parsers.SAXParser from [Module \"deployment.FLUX-WSApp.
war\" from Service Module Loader]
Caused by: java.lang.classNotFoundException: org.apache.xerces.parsers.SAXParser from [Module \"deploym
ent.FLUX-WSApp.war\" from Service Module Loader]"}}}}
所以我查看了模块是否已加载（他是）：

}
}
我可以比较它们，但是看不到任何区别。（特别是在standalone.xml中）。
jar和main / module.xml在两个服务器上相同。 ACL完全相同。
cat ~/modules/system/layers/base/org/apache/xerces/main/module.xml

我不能编辑部署战争的代码，我不是开发人员，但可以反编译它。 我注意到有关org.apache.xerces的唯一参考是：
package org.springframework.instrument.classloading;
...
/**
* ClassLoader decorator that shadows an enclosing ClassLoader,* applying registered transformers to all affected classes.
...
public class ShadowingClassLoader extends DecoratingClassLoader {
/** Packages that are excluded by default */
public static final String[] DEFAULT_EXCLUDED_PACKAGES =
new String[] {"java.","javax.","sun.","oracle.","com.sun.","com.ibm.","COM.ibm.","org.w3c.","org.xml.","org.dom4j.","org.eclipse","org.aspectj.","net.sf.cglib","org.springframework.cglib","org.apache.xerces.","org.apache.commons.logging."};
有人可以帮忙吗？ 我应该去哪里找？
解决方法
我已经完全重新安装了wildfly。该问题不再发生。
