在Liferay 7中使用apache-cxf Web服务时出现链接错误 [英] Linkage Error while Consuming apache-cxf Web Services in Liferay 7
问题描述
我正在尝试使用apache-cxf Web服务在Liferay-7 portlet中，我在linux环境中遇到以下错误。
I am trying to consume apache-cxf Web Services In Liferay-7 portlet ,I got the following error in linux environment.
13：39：14,374 ERROR [ http-nio-4080-exec-9] [status_jsp：950] com.liferay.portal.kernel.portlet.PortletContainerException：com.liferay.portal.kernel.portlet.PortletContainerException：javax.servlet.ServletException：java.lang.LinkageError ：com / sun / org / apache / xpath / internal / jaxp / XPathImpl
13:39:14,374 ERROR [http-nio-4080-exec-9][status_jsp:950] com.liferay.portal.kernel.portlet.PortletContainerException: com.liferay.portal.kernel.portlet.PortletContainerException: javax.servlet.ServletException: java.lang.LinkageError: com/sun/org/apache/xpath/internal/jaxp/XPathImpl
如果我在liferay 7 windows环境中运行相同的portlet它运行正常
If I run the same portlet in liferay 7 windows environment it is working fine
以下是示例jsp代码（view.jsp）
And here is the sample jsp code (view.jsp)
<portlet:defineObjects />
<%@ page import="org.apache.cxf.endpoint.Client" %>
<%@ page import="org.apache.cxf.jaxws.endpoint.dynamic.JaxWsDynamicClientFactory" %>
<%@ taglib uri="http://java.sun.com/portlet_2_0" prefix="portlet" %>
<%
String endpoint="http://*******/***-ws/soap/login?wsdl";
String method ="login";
String uname ="admin";
String pwd = "admin";
String result = "";
Object[] params = new Object[2] ;
params[0] = (Object)uname;
params[1] = (Object)pwd;
result = call(endpoint, method, params);
System.out.println("Result : "+result);
%>
<%!
public static String call(String endpoint, String method, Object[] params) {
JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance();
try {
Client client = dcf.createClient(endpoint);
System.out.println("Client Object Create successfully :");
Object[] returnVals = client.invoke(method, params);
//extract returned value. getting 1st value as sakai ws calls returns only one value.
if(returnVals!=null && returnVals.length>0)
return (String)returnVals[0];
}
catch (Exception e) {
e.printStackTrace();
System.out.println("A connection error occurred: " + e.getClass() + ": " + e.getMessage());
}
return null;
}
%>
问题发生在
客户端客户端= dcf.createClient（端点） ;

我的方法不同。我在Liferay实例上安装了必要的Apache CXF模块作为OSGi包，之后我使用导出到OSGi容器的CXF API构建了一个简单的WS客户端。作为OSGIi包安装的Apache CXF模块。
My approach was different. I installed the necessary Apache CXF modules as an OSGi bundle on the Liferay instance, after which I built a simple WS client using the CXF APIs exported to the OSGi container. Apache CXF modules installed as OSGIi bundle.

安装九个元素Apache CXF框架可以通过telnet连接到Apache Felix GoGo Shell来执行。 Liferay 7门户运行后，可以通过执行命令安装Apache CXF框架安装$ URL_CXF_BUNDLE
The installation of the nine elements of the Apache CXF framework can be performed by connecting via telnet to the Apache Felix GoGo Shell. Once the Liferay 7 portal is running, the Apache CXF framework can be installed by executing the commands install $URL_CXF_BUNDLE
