weblogic服務器中的CXF Webservice問題

Question

我想從我的web應用程序中調用web服務，它可以很好地與Apache Tomcat或JBoss等服務器一起工作，但在Weblogic服務器中會出現以下異常。

任何解決方案？

Answer 1

在你的weblogic-application.xml中，你必須定義JAXB提供者是從CXF的一個沒有太陽的參考實現（了com.sun.xml ...）。

添加以下所提到的文件

<prefer-web-inf-classes>true</prefer-web-inf-classes> 

這導致倒車類加載過程的。因此，您在戰爭中提供的類會在來自weblogic的類之前加載。

編輯：

的提供程序的文檔說：

用於定位提供商子類使用該算法包含 以下步驟：

• 如果資源用META-INF/services/javax.xml.ws.spi.Provider這個名字存在，那麼它的第一行
  一行，如果存在，則用作實現類的UTF-8編碼名稱。
• 如果$ java.home/LIB/jaxws.properties文件存在，並且它是可讀的由java.util.Properties.load（InputStream的）方法，它
  包含其鍵是javax.xml.ws一個條目。 spi.Provider，那麼該條目的值將被用作實現類的名稱。
• 如果定義了名稱爲javax.xml.ws.spi.Provider的系統屬性，則其值將用作類的實現名稱
  類。
• 最後，使用默認實現類名稱。

所以，如果改變了類加載不夠添加以下

<prefer-application-resources> 
    <resource-name>META-INF/services/javax.xml.ws.spi.Provider</resource-name> 
</prefer-application-resources> 

到Weblogic-application.xml中
