CORB：未定义的外部变量 fn:QName("","URI")

Question

我是 CORB 新手，尝试使用 Java 代码删除文档，但出现 com.marklogic.xcc.exceptions.XQueryException: XDMP-EXTVAR: (err:XPDY0002) declare variable $URI as xs:string* external; -- Undefined external variable fn:QName("","URI") 异常。

我在我的 java 项目中使用 CORB 2.5.0 作为 Maven 依赖项。

URIS_MODULE就是get-uri.xql

xquery version "1.0-ml";
let $uris := cts:uris()
return (count($uris), $uris)

PROCESS-MODULE 是 transform-docs.xqy

xquery version "1.0-ml";
declare variable $URI as xs:string* external;
xdmp:document-delete($URI)

这里是执行模块的java代码，

    Properties properties = new Properties();
    properties.setProperty(Options.XCC_CONNECTION_URI, "xcc://admin:admin-password@localhost:8061/test");
    properties.setProperty(Options.THREAD_COUNT, Integer.toString(8));
    properties.setProperty(Options.PROCESS_MODULE, "src/test/resources/transform-docs.xqy.xqy|ADHOC");
    properties.setProperty(Options.URIS_MODULE, "src/test/resources/get-uri.xqy|ADHOC");
    properties.setProperty(Options.MODULES_DATABASE, "8061-test-modules");

    Manager executor = new Manager();
    executor.init(properties);
    executor.run();

执行上述代码后，我收到此警告并且代码将永远执行，

    Warning at char 9 in xsl:with-param/@select on line 106 column 123 of jobStatsToJson.xsl:
  FODC0002: I/O error reported by XML parser processing
  jar:file:/C:/Users/Shivling%20Bhandare/.m2/repository/com/marklogic/marklogic-corb/2.5.0/marklogic-corb-2.5.0.jar!/: no entry name specified
Warning at char 9 in xsl:with-param/@select on line 107 column 118 of jobStatsToJson.xsl:

  jar:file:/C:/Users/Shivling%20Bhandare/.m2/repository/com/marklogic/marklogic-corb/2.5.0/marklogic-corb-2.5.0.jar!/jobStatsToJson.xsl

更新这个错误是通过更改 CoRB 版本而发生的，但现在我遇到了这个异常，

最新代码是

        Properties properties = new Properties();
        properties.put(Options.PROCESS_MODULE, "src/test/resources/transform-docs.xqy");
        properties.put(Options.URIS_MODULE, "src/test/resources/get-uris.xqy");
        properties.put(Options.THREAD_COUNT, "20");
        properties.put(Options.MODULE_ROOT, "/");
        properties.put(Options.MODULES_DATABASE, "8067-TCOMP-modules");
        properties.put(Options.INSTALL, "1");
        properties.put(Options.XCC_DBNAME, "TCOMP");
        properties.put(Options.XCC_PORT, "8067");
        properties.put(Options.XCC_HOSTNAME, "localhost");
        properties.put(Options.XCC_USERNAME, "admin");
        properties.put(Options.XCC_PASSWORD, "admin");

        Manager manager = new Manager();
        manager.init(properties);
        manager.run();

上面提到的错误通过更改 CoRB 版本消失了，但现在我得到了

WARNING: Connection error count for ContentSource user=admin, cb=TCOMP [provider: address=localhost/127.0.0.1:8067, pool=1/64] is 1. Max limit is 3.

感谢任何帮助。

Answer 1

如果您想要运行 CoRB 作业，那么您想要使用 Manager class。

参考这个集成测试的例子： https://github.com/marklogic-community/corb2/blob/master/src/test/java/com/marklogic/developer/corb/ManagerIT.java#L100

ModuleExecutorclass用于执行单个主模块

CoRB 管理器和 ModuleExecutor 都以相似的方式配置，具有相同的属性，因此 ModuleExecutor 试图执行您配置的 PROCESS-MODULE 并且因为没有默认值外部变量 $URIS 的值，它会引发错误。

谢谢 Mads Hansen，如果没有您的意见无法解决这个问题，

完整的解决方案是，

使用的 Corb 版本

        <dependency>
            <groupId>com.marklogic</groupId>
            <artifactId>marklogic-corb</artifactId>
            <version>2.4.0</version>
        </dependency>

使用的 XCC 版本

        <dependency>
            <groupId>com.marklogic</groupId>
            <artifactId>marklogic-xcc</artifactId>
            <version>10.0.6</version>
        </dependency>

属性和管理器配置

        Properties properties = new Properties();
        properties.put(Options.PROCESS_MODULE, "src/test/resources/transform-docs.xqy|ADHOC");
        properties.put(Options.URIS_MODULE, "src/test/resources/get-uris.xqy|ADHOC");
        properties.put(Options.THREAD_COUNT, "20");
        properties.put(Options.MODULE_ROOT, "/");
        properties.put(Options.MODULES_DATABASE, "8067-test-modules");
        properties.put(Options.INSTALL, "1");
        properties.put(Options.XCC_DBNAME, "test");
        properties.put(Options.XCC_PORT, "8067");
        properties.put(Options.XCC_HOSTNAME, "localhost");
        properties.put(Options.XCC_USERNAME, "admin");
        properties.put(Options.XCC_PASSWORD, "admin");

        Manager manager = new Manager();
        manager.init(properties);
        manager.run();
