domino的java開發，找不到方法故障處理過程
故障現象：
2010-04-18 14:09:20 HTTP JVM: java.lang.NoSuchMethodError
2010-04-18 14:09:20 HTTP JVM: at org.apache.axis.deployment.wsdd.WSDDDocument.setDocument(WSDDDocument.java:136)

===============================================
分析：
1、 類是找到了，但找不到相關方法。應該是找錯了同名類。現在關鍵是要定位出 “org.apache.axis.deployment.wsdd.WSDDDocument” 類在哪個 jar 包。
用以面的測試代碼來調試：
import lotus.domino.*;
import java.io.*;
import java.util.*;
import java.lang.*;
public class JavaAgent extends AgentBase {
public void NotesMain() {
try {
Session session = getSession();
AgentContext agentContext = session.getAgentContext();
Class test = Class.forName("org.apache.axis.deployment.wsdd.WSDDDocument");
System.out.println(test.getClassLoader().getResource(""));
System.out.println(ClassLoader.getSystemResource(""));
System.out.println(test.getResource(""));
System.out.println(test.getResource("/"));
System.out.println(new File("").getAbsolutePath());
System.out.println(System.getProperty("user.dir"));
} catch(Exception e) {
e.printStackTrace();
}
}
}
2、運行第一步寫的那個類後，報下面的權限錯誤：
2010-04-18 16:35:17 HTTP JVM: java.security.AccessControlException: access denied (java.lang.RuntimePermission getClassLoader)
2010-04-18 16:35:17 HTTP JVM: at java.security.AccessControlContext.checkPermission(AccessControlContext.java:272)
2010-04-18 16:35:17 HTTP JVM: at java.security.AccessController.checkPermission(AccessController.java:399)
2010-04-18 16:35:17 HTTP JVM: at java.lang.SecurityManager.checkPermission(SecurityManager.java:545)
2010-04-18 16:35:17 HTTP JVM: at java.lang.Class.getClassLoader(Class.java:433)
2010-04-18 16:35:17 HTTP JVM: at JavaAgent.NotesMain(JavaAgent.java:16)
2010-04-18 16:35:17 HTTP JVM: at lotus.domino.AgentBase.runNotes(Unknown Source)
2010-04-18 16:35:17 HTTP JVM: at lotus.domino.NotesThread.run(NotesThread.java:249)
說明沒有執行權限。
3、由於沒有權限，所以執行上面的 jar 包定位代碼時報錯，需要在 " domino\jvm\lib\security\java.policy" 文件中加入：
//開放所有權限
permission java.security.AllPermission;
然後再執行剛纔測試程序
4、運行結果：
HTTP JVM: file:/maildata/
HTTP JVM: file:/maildata/
HTTP JVM: jar:file:/opt/lotus/notes/65060/sunspa/jvm/lib/ext/axis.jar!/org/apache/axis/deployment/wsdd/
HTTP JVM: file:/maildata/
HTTP JVM: /maildata
HTTP JVM: /maildata
HTTP JVM: file:/maildata/
HTTP JVM: jar:file:/opt/lotus/notes/65060/sunspa/jvm/lib/ext/axis.jar!/org/apache/axis/deployment/wsdd/
HTTP JVM: file:/maildata/
HTTP JVM: /maildata
HTTP JVM: /maildata
5、把/opt/lotus/notes/65060/sunspa/jvm/lib/ext/axis.jar 這個jar包換掉就解決了
