Undeployment Failure 項目中缺少jar檔案

解決辦法：

把項目中引用的jar檔案重新加一遍就行了，基本原因就是以前的jar檔案不存在了，但是項目資訊中還有，即項目的.classpath檔案中還有不存在的jar檔案引用。

可以右鍵點項目名稱，選擇Properties,選擇Java Build Path,選擇Libraries,把所有項目中的jar都remove，然後再點"add jars"，把項目中的jar檔案都加進來，再次部署就正常了

Tomcat 部署 Could not copy all resources to 或者Undeployment Failure could not be redeployed

Tomcat 部署，在部署可能會出現以下問題：

Deployment failure on Tomcat 6.x. Could not copy all resources to
E:/apache-tomcat-6.0.16/webapps/HebbnWebServices. If a file is locked,
you can wait until the lock times out to redeploy, or stop the server
and redeploy, or manually remove the deployment at
E:/apache-tomcat-6.0.16/webapps/HebbnWebServices

再次點部署按鈕時就會提示如下：

Undeployment Failure could not be redeployed because it could not be
completely removed in the undeployment phase. the most common cuase of
this problem is attempting to redeploy while the server is running,which
has locked one or more files.

to correct the deployment you will need to stop the server and then redeploy the project before restarting the server.

解決的辦法就是在Eclipse中把項目中引用的jar檔案重新加一遍就行了，基本原因就是以前的jar檔案不存在了，但是項目資訊中還有，即項目的.classpath檔案中還有不存在的jar檔案引用。

可以右鍵點項目名稱，選擇Properties,選擇Java Build Path,選擇Libraries,把所有項目中的jar都remove，然後再點"add jars"，把項目中的jar檔案都加進來，再次部署就正常了。
