XSD SchemaFactory 错误 - Java 6
在下面的代码中，我尝试验证 XML。当我从 eclipse 运行它时发现一切正常。当我在 weblogic 上部署它时，代码失败并出现错误：“处理 src-resolve 时出现 SAX 异常：无法将名称 XX:sometag 解析为（n）‘类型定义’组件。”
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
System.out.println("schemaFactory -> " + schemaFactory.getClass());
Schema schema = schemaFactory.newSchema(resourceHandler.getXSDStreams());
StreamSource xmlContent = new StreamSource(new StringReader(requestXML));
Validator validator = schema.newValidator();
validator.validate(xmlContent);
这是在 eclipse 上为 Schema Factory 生成的输出： 模式工厂-> class com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory
在 Weblogic 上，具有相同 JAR 文件的相同代码会出现上述错误。 schemaFactory 完全相同。
Config - 2
我尝试设置系统属性来加载 xerces 文件并将 xerces 添加到类路径中，
String schemaFactoryProperty = "javax.xml.validation.SchemaFactory:" + XMLConstants.W3C_XML_SCHEMA_NS_URI;
System.setProperty(schemaFactoryProperty,"org.apache.xerces.jaxp.validation.XMLSchemaFactory");
模式工厂的输出仍然保持不变：“schemaFactory -> class com.sun.org.apache.xerces.internal.jaxp。 validation.XMLSchemaFactory”，但这次错误更改为：
java.lang.IllegalArgumentException: Source parameter of type 'javax.xml.transform.stream.StreamSource' is not recognized this SchemaFactory.

我使用 Java 6 和 WLS 10.3.0 (Java 6) 并使用 Spring 框架。
In the code below, I am trying to validate a XML. Everything works find when i run it from eclipse. When i deploy it on weblogic the code fails with error: "SAX Exception while processingsrc-resolve: Cannot resolve the name XX:sometag to a(n) 'type definition' component."
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
System.out.println("schemaFactory -> " + schemaFactory.getClass());
Schema schema = schemaFactory.newSchema(resourceHandler.getXSDStreams());
StreamSource xmlContent = new StreamSource(new StringReader(requestXML));
Validator validator = schema.newValidator();
validator.validate(xmlContent);
This is the output generated on eclipse for Schema Factory:
schemaFactory -> class com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory
On Weblogic the same code with the same JAR files gives the error mentioned above. The schemaFactory is exactly the same.
Config - 2
I tried setting the System property to load xerces files and added xerces to the classpath
String schemaFactoryProperty = "javax.xml.validation.SchemaFactory:" + XMLConstants.W3C_XML_SCHEMA_NS_URI;
System.setProperty(schemaFactoryProperty,"org.apache.xerces.jaxp.validation.XMLSchemaFactory");
Still the output for the schema factory remains the same: "schemaFactory -> class com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory" but this time the error changed to:
java.lang.IllegalArgumentException: Source parameter of type 'javax.xml.transform.stream.StreamSource' is not recognized this SchemaFactory.

I am on Java 6 and WLS 10.3.0 (Java 6) and using Spring framework.

开始工作了（4 小时后！！！）。
在本地，它工作的原因：架构是从文件夹加载的，因此 XSD 中的导入就像以前一样工作。
在服务器上，我放入了一个 jar 文件，因此 sourceLocation="SomeFile.xsd" 从未用于生成文件，因为实际路径是 URI。
是什么解决了它：
1）我更改了加载模式的顺序（从无导入 - >所有导入）以确保当前xsd编译时它的所有依赖项已经在schemaFactory中（这是可能的，因为我没有下一步导入，所以我有一个明确的顺序，即首先加载哪个文件等等）
2）我也可以做的是 - 将所有 XSD 合并到一个文件中。
3) 或者我可以将 XSD 保存在 web-inf/ 中，然后查找它们而不是 JAR 文件。然后 import sourceLocation="" 就会找到该文件。
希望这对某人有帮助！
干杯。

Got it working (after 4 hrs !!!).
On local why it worked: The Schemas were loaded from a folder so the imports within the XSD like used to work.
On Server i had put in a jar file so the sourceLocation="SomeFile.xsd" never used to result in a file as the actual path was a URI.
What fixed it:
1) I changed the sequence in which i load the schemas (from no imports --> all imports) to make sure when the current xsd compiles all dependencies for it are already in the schemaFactory (It was possible as i did not have nexted imports so i had a clear order of what file to load first and so on)
2) What i could have done as well was - combine all XSDs to one file.
3) OR I could have kept the XSD in web-inf/ and then looked them up instead of a JAR file. Then the import sourceLocation="" would have found that file.
Hope this helps someone !!!
Cheers.
