我遇到了和Yeray完全一样的问题，遇到了这个帖子。我现在已经找到了一个解决方案，所以我回来分享我的代码，我希望可以帮助Yeray或其他人。

public class InsertDepartment {

public static final String DRIVER = "org.exist.xmldb.DatabaseImpl";
public final static String URI = "xmldb:exist://localhost:8080/exist/xmlrpc";
public final static String COLLECTION = "/db/first_steps";
public final static String USERNAME = "admin";
public final static String PASSWORD = "";

public static void main(String[] args) throws Exception {
    String value = "";

    Class cl = Class.forName(DRIVER);
    Database database = (Database) cl.newInstance();
    DatabaseManager.registerDatabase(database);
    Collection col = DatabaseManager.getCollection(URI + COLLECTION, USERNAME, PASSWORD);

    int depNumber = 42;
    String depName = "Department 42";
    String depAddress = "42 Galaxy Avenue, Betelgueuse 23458 OH";

    String sQuery = "update insert <department><dep_number>" + depNumber
            + "</dep_number><dep_name>" + depName + "</dep_name><dep_address>"
            + depAddress + "</dep_address></department> into /departments";

    EXistXQueryService service = (EXistXQueryService) col.getService("XQueryService", "1.0");
    service.setProperty("indent", "yes");
    service.query(sQuery);
}

请注意，为了使这段代码正常工作，我在我的项目中使用了以下库列表。这些代码可能不需要。

exist-xqj-1.0.1.jar
j8fu-1.21.jar
log4j-1.2-api-2.11.0.jar
log4j-api-2.11.0.jar
log4j-core-2.11.0.jar
log4j-jul-2.11.0.jar
log4j-slf4j-impl-2.11.0.jar
org.apache.commons.pool.jar
org-apache-commons-logging.jar
ws-commons-util-1.0.2.jar
xmldb-api-1.7.0.jar
xmlrpc-client-3.1.3.jar
xmlrpc-common-3.1.3.jar
xqj2-0.0.1.jar
xqjapi.jar
exist.jar
exist-optional.jar

此外，我必须将文件log4j2.xml添加到项目的src文件夹中。你可以在这篇文章中找到这个文件的示例。
