How do I make Weblogic 10 prefer the jars in myApp.war:/WEB-INF/lib/ without throwing VerifyErrors?
提问by neu242
The Weblogic classloader seems to prefer system libraries over the libraries in my war's WEB-INF/lib/.
Weblogic 类加载器似乎更喜欢系统库而不是我的WEB-INF/lib/.
I've tried setting the following in WEB-INF/weblogic.xml, without success:
我试过在 中设置以下内容WEB-INF/weblogic.xml，但没有成功：
<weblogic-web-app>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
This just gives me a lot of VerifyErrors:
这只是给了我很多验证错误：

I was never able to fix this satisfactorily, other than by specifying -Djavax.xml.parsers.SAXParserFactory=[xerces sax parser factory class name](and so on for the other JAXP factories like validation SchemaFactory) when starting Weblogic.
除了-Djavax.xml.parsers.SAXParserFactory=[xerces sax parser factory class name]在启动 Weblogic 时指定（以及其他 JAXP 工厂，如验证 SchemaFactory等）之外，我一直无法令人满意地解决这个问题。
None of the filtering / prefer-web-infstuff worked, possibly due to Weblogic requiring JAXP libraries on startup before it even reads any of the WAR / EAR config files.
过滤/prefer-web-inf东西都不起作用，可能是因为 Weblogic 在启动时需要 JAXP 库，甚至在它读取任何 WAR/EAR 配置文件之前。

I had this problem too with tomcat-arquillian. Turns out "xml-apis 2.0.2" was in my classpath, which is actually xml-apis 1.0.b2 and which is too old to be compatible with xercesImpl 2.9.1 which requires xml-apis 1.3.04.
我在使用 tomcat-arquillian 时也遇到了这个问题。原来“xml-apis 2.0.2”在我的类路径中，它实际上是 xml-apis 1.0.b2，它太旧了，无法与需要 xml-apis 1.3.04 的 xercesImpl 2.9.1 兼容。
