问题描述
我需要在Lotus Notes 6.5 DB中编写JavaAgent来访问Web服务。我为此目的使用了Axis Apache API。我创建了一个Java代理,并使用编辑项目按钮在代理中添加了轴的jar文件。
I needed to write a JavaAgent in a Lotus Notes 6.5 DB to access a web service. I used Axis Apache API for this purpose. I created A Java agent and added the jar files of axis in the agent by using Edit Project button.
以下是代理代码:
import lotus.domino.*;
import javax.xml.*;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.net.URL;
public class JavaAgent extends AgentBase {
public void NotesMain() {
try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();
String endpoint = "http://ws.apache.org:5049/axis/services/echo";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpoint) );
call.setOperationName(new QName("http://soapinterop.org/", "echoString"));
String ret = (String) call.invoke( new Object[] { "Hello!" } );
System.out.println("Sent 'Hello!', got '" + ret + "'");
} catch(Exception e) {
e.printStackTrace();
}
}
}
以下是抛出的异常:
java.lang.ExceptionInInitializerError: org.apache.commons.discovery.DiscoveryException: No implementation defined for org.apache.commons.logging.LogFactory

我很想跟随互联网上的一些链接,但我无法得到它要求的确切内容。例如:
I thried to follow some links on the internet like, But i was not able to get exactly what it was asking to do. eg: http://www-10.lotus.com/ldd/nd6forum.nsf/55c38d716d632d9b8525689b005ba1c0/40d033fba3897f4d85256cd30034026a?OpenDocument
任何帮助将是巨大的。我想做的就是写一个代理,这样我就可以访问一个网络服务,比如w3schools上的温度转换网络服务。
Any help will be great. All i wanted to do is write an agent so that i can access a web service, say temperature conversion web service on w3schools. http://www.w3schools.com/webservices/tempconvert.asmx?op=FahrenheitToCelsius
推荐答案
我用Google搜索了您的错误消息,这是第一次点击:
I googled with your error message and this is the first hit:
建议使用 commons-logging.properties 文件:
org.apache.commons.logging.Log = org.apache.commons.logging.impl.Log4JLogger
org.apache.commons.logging.LogFactory = org.apache.commons.logging.impl.LogFactoryImpl
或将其放入您的代码:
@BeforeClass
public static void beforeClass() {
System.setProperty("org.apache.commons.logging.Log", "org.apache.commons.logging.impl.Log4JLogger");
System.setProperty("org.apache.commons.logging.LogFactory", "org.apache.commons.logging.impl.LogFactoryImpl");
}
可能你已经尝试过这个,因为它是谷歌的第一个热门但只是如果......
Probably you've already tried this because it's the first hit with google but just in case...
这篇关于使用axis api的Lotus Notes 6.5中的JavaAgent给出了Exception“没有为org.apache.commons.logging.LogFactory定义的实现”。的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
