JBoss 6 發佈WAR工程錯誤 Trying to resolve systemId as a non-file URL: xxxx 解決辦法

我把項目打了個WAR包，在JBoss 4 下發布可以正常工作，但在JBoss 6 下發布拋出如下錯誤：

08:57:17,305 WARN  [org.jboss.util.xml.JBossEntityResolver] Trying to resolve systemId as a non-file URL: http://java.sun.com/j2ee/dtds/web-jsptaglib_1_1.dtd
08:57:59,695 ERROR [org.jboss.kernel.plugins.dependency.AbstractKernelController] Error installing to Parse: name=vfs:///C:/tools/jboss-6.1.0.Final/server/default/deploy/GHS_Utility_GUI.war state=PreParse mode=Manual requiredState=Parse: org.jboss.deployers.spi.DeploymentException: Error creating ma

DEPLOYMENTS IN ERROR:
  Deployment "vfs:///C:/tools/jboss-6.1.0.Final/server/default/deploy/GHS_Utility_GUI.war" is in error due to the following reason(s): java.net.ConnectException: Connection timed out: connect

看了一下log，發現錯誤的根源是找不到那個URL：

http://java.sun.com/j2ee/dtds/web-jsptaglib_1_1.dtd

解決方案：

（1）因爲這個URL是在bsf-2.3.0.jar裏，

（2）所以在war裏打開 \WEB-INF\bsf-2.3.0.jar\META-INF\taglib.tld

（3）編輯taglib.tld， 把

http://java.sun.com/j2ee/dtds/web-jsptaglib_1_1.dtd

替換成：

http://java.sun.com/j2ee/dtds/jsptaglibrary_1_2.dtd

問題就解決了，不知這種方案可否解決你的問題，歡迎回復。
