１、測試"Sample 655: Message Relay - Basics"時，出現”Login failed! Please recheck Server URL and try again.“錯誤訊息
http://wso2.org/project/esb/java/4.0.3/docs/samples/misc_samples.html

狀況說明：
依照範例說明，將axis2.xml檔案中，
org.wso2.carbon.relay.ExpandingMessageFormatter
org.wso2.carbon.relay.BinaryRelayBuilder
這兩種Formatter與Builder之設定“取消註解”(生效)後，範例可以正常完成。
但是，登入Management Console後，卻無法登入，會跳出如下訊息的dialog
Login failed! Please recheck Server URL and try again.
 

若恢復原設定值，則又可以順利登入。（但是就無法達到想要的結果了）

此外，在Server Console上，有底下錯誤訊息：
Caused by: org.apache.axis2.AxisFault: namespace mismatch require http://authentication.services.core.carbon.wso2.org found http://ws.apache.org/commons/ns/payload 

處理方式及原因說明：
由底下網址
http://docs.wso2.org/display/ESB403/Message+Relay+Module
可以看到一段說明，
This module is designed to be used by Admin Services that runs inside the ESB. All the admin services are running with content type: application/soap+xml. So if a user wants to use admin console and use the ESB for receiving messages with content type application/soap+xml, this module should be used.

所以，依照該網址上的步驟，啟用relay module之後，即可登入Carbon。

 ２、ESB部署到JBoss AP Server時 - 出現"Database Error - Table "UM_DIALECT" not found"錯誤訊息！

2012-03-01 09:17:12,104 ERROR [org.wso2.carbon.user.core.util.DatabaseUtil] (Start Level Event Dispatcher) Database Error - Table "UM_DIALECT" not found; SQL statement:
SELECT COUNT(UM_ID) FROM UM_DIALECT WHERE UM_TENANT_ID=? [42102-140]
org.h2.jdbc.JdbcSQLException: Table "UM_DIALECT" not found; SQL statement:
SELECT COUNT(UM_ID) FROM UM_DIALECT WHERE UM_TENANT_ID=? [42102-140]
at org.h2.message.DbException.getJdbcSQLException(DbException.java:327)
at org.h2.message.DbException.get(DbException.java:167)

處理方式及原因說明：
應該是資料庫的對應設定沒有設定正確，
檢查
１、registry.xml或usr-mgt.xml中，資料庫所在目錄設定不正確。
２、/etc/profile中的CARBON_HOME是否設定正確。或是，直接以export CARBON_HOME=<wso2主目錄>後，再啟動JBoss AP Server。

３、新增message processor時 - 出現"Couldn't find repository location './samples/axis2Client/client_repo'"錯誤訊息！

2012-03-01 10:38:46,104 INFO [org.apache.axis2.deployment.FileSystemConfigurator] (http-0.0.0.0-8443-10) Couldn't find repository location './samples/axis2Client/client_repo'
2012-03-01 10:38:46,104 ERROR [org.apache.synapse.message.processors.forward.BlockingMessageSender] (http-0.0.0.0-8443-10) Error initializing BlockingMessageSender : Couldn't find repository location './samples/axis2Client/client_repo'
org.apache.axis2.AxisFault: Couldn't find repository location './samples/axis2Client/client_repo'

處理方式及原因說明：未處理
 

４、Integrating Different Systems with WSO2 ESB，遇到的一些問題
http://wso2.org/library/articles/2012/01/integrating-different-systems-with-wso2-esb

狀況說明：
１、不曉得ProcessDocument這個物件要建立在哪裡？

２、解壓縮"sample_8.zip"之後，按照目錄下的README.txt，要建置Builder及Formatter時，
　　在sample/extensions目錄底下，執行mvn clean install -Dmaven.test.skip=true -o，出現Error訊息而無法完成：

[root@wso2 extensions]# /opt/maven/bin/mvn clean install -Dmaven.test.skip=true -o

[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException

處理方式及原因說明：
１、ProcessDocument是
　　sample/extensions/src/main/java/sample/shop/builder/CSVFileBuilder.java
　　這個Class底下的一個Method，用來將CSV檔轉成XML檔。

２、透過mvn -h這個指令，以及底下網址，
　　http://juvenshun.iteye.com/blog/213959
　　http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html#Lifecycle_Reference
　　http://maven.apache.org/maven-1.x/plugins/test/properties.html
　　了解到mvn clean install -Dmaven.test.skip=true -o這條指令， 是表示
　　A. 清除上一次建構所生成的檔案
　　B. 依照extensions/src/pom.xml的配置內容，將package(Builder與Formatter)建置到本地端的repository
　　C. 忽略測試的動作
　　D. 離線進行動作 
　　
　　指令之所以錯誤，可能是因為Maven需要上網去下載相關的資訊，而這台主機沒有設定Proxy連線資
　　訊導致無法連上網路，也就無法下載資訊了。
　　編輯$MAVEN_HOME/conf/settings.xml內容中，Proxy的相關資訊後，即可順利連上網路下載相關
　　資訊進行compile。

　　最後編譯後，節錄最後顯示的資訊如後：
[DEBUG] Configuring mojo org.apache.maven.plugins:maven-install-plugin:2.3.1:install from plugin realm ClassRealm[plugin>org.apache.maven.plugins:maven-install-plugin:2.3.1, parent: sun.misc.Launcher$AppClassLoader@13f5d07]

　　這時，在sample/extensions目錄底下，會產生一個"target"的目錄，
　　底下會有範例所客製化的Builder與Formatter類別編譯後之class檔，以及shop-1.0.0.jar檔。

－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－－
　　另外，
　　README.txt中還提到要將sample/conf/axis2.xml複製到repository/conf/目錄中，如此一來就會將我
　　們原本的axis2.xml配置都蓋掉了，所以，應該是在/repository/conf/axis2.xml中，"Formatter"區塊下
　　，新增
　　<messageFormatter contentType="text/csv"
        　　           class="sample.shop.formatter.EmailMessageFormatter"/>
　　引用CSV格式轉成Email格式的Class，

　　同樣的， 在"Builder"區塊下，新增
　　<messageBuilder contentType="text/csv"
　　　　          class="sample.shop.builder.CSVFileBuilder"/>
　　引用CSV格式轉成XML格式的Class。 

　　此外，在Transport區塊中，也要設定
　　<transportSender name="mailto" class="org.apache.axis2.transport.mail.MailTransportSender">
　　底下的內容，才能進行E-mail的寄送。

　　設定完成後，重啟ESB。 

５、在Management Console上的Source View中，按下「Update」鍵更新時，
　　出現「Error while updating the mediation configuration.」錯誤訊息。
　　而且，有些Proxy Service無法被顯示出來。

狀況說明：
　在Management Console左側選單按下Service Bus / Source View，可以在右邊區塊中顯示XML內容。
 

嘗試在Source View中，直接編輯內容，然後按下最底下「Update」鍵，想說能夠直接更新設定內容，
結果，彈出一個視窗顯示「Error while updating the mediation configuration.」訊息，
 
然後回復到原本的設定內容，然後有一些Proxy Service就無法顯示在列表上，只能由Source View上
看到內容。 

處理方式及原因說明：
重啟服務後，就有恢復了。
不過，只敢從Proxy Service列表那邊去修改，不敢從Soruce View去修改了。
