Java 客戶端 Axis2 OMException

Question

我從 Axis2 版本 1.6.0 的 wsdl 文件生成了 java 類。

當我調用該服務時，出現以下異常：

org.apache.axiom.om.OMException：未找到功能“默認”的元工廠； 這通常意味着 axiom-impl.jar 不在類路徑中或無法讀取 META-INF/axiom.xml 資源

使用的依賴項axis2是：

        <dependency>
            <groupId>org.apache.ws.commons.schema</groupId>
            <artifactId>XmlSchema</artifactId>
            <version>1.4.7</version>
        </dependency>
        <dependency>
            <groupId>org.apache.axis2</groupId>
            <artifactId>axis2</artifactId>
            <version>1.6.2</version>
        </dependency>
        <dependency>
            <groupId>org.apache.ws.commons.axiom</groupId>
            <artifactId>axiom-api</artifactId>
            <version>1.2.12</version>
        </dependency>
        <dependency>
            <groupId>org.apache.ws.commons.axiom</groupId>
            <artifactId>axiom-impl</artifactId>
            <version>1.2.12</version>
        </dependency>

我該如何解決這個異常？

Answer 1

我找到了這個解決方案，在axis2 1.6.2中axiom.xml不存在，所以我繼續使用以下依賴項：
