将应用程序升级到Grails 2后JBoss部署错误(JBoss deploy error after upgrading app to Grails 2)
我已将Grails应用程序从1.3.6升级到2.1.1。 经过一些修复和整理后，run-app可以运行（大多数情况下，还有一些已弃用的问题需要处理）。 grails war也可以毫无错误地构建。
然而，当我部署到JBoss（4.2.2）时，与grails 1.3.6战争相同，我得到了这个错误：

谢谢。
I've upgraded a Grails app from 1.3.6 to 2.1.1. After some fixing and tidying up, run-app works (for the most part, still some deprecated issues to deal with). grails war also builds without error.
When I deploy into JBoss (4.2.2) however, the same as has been done for the grails 1.3.6 war, I get this error:
Caused by: javax.management.ReflectionException: Cannot find setter method setLoader StandardContext[null] at org.apache.tomcat.util.modeler.ManagedBean.getSetter(ManagedBean.java:560) at org.apache.tomcat.util.modeler.BaseModelMBean.setAttribute(BaseModelMBean.java:407) at org.jboss.mx.server.RawDynamicInvoker.setAttribute(RawDynamicInvoker.java:70) at org.jboss.mx.server.MBeanServerImpl.setAttribute(MBeanServerImpl.java:608) at org.jboss.web.tomcat.service.TomcatDeployer.performDeployInternal(TomcatDeployer.java:212) at org.jboss.web.tomcat.service.TomcatDeployer.performDeploy(TomcatDeployer.java:104) at org.jboss.web.AbstractWebDeployer.start(AbstractWebDeployer.java:375) ... 112 more Caused by: java.lang.NoSuchMethodException: org.apache.catalina.core.StandardContext.setLoader(org.apache.catalina.Loader) at java.lang.Class.getMethod(Class.java:1605) at org.apache.tomcat.util.modeler.ManagedBean.getSetter(ManagedBean.java:553) ... 118 more 2012-11-08 16:09:51,604 INFO [org.jboss.web.tomcat.service.TomcatDeployer] deploy, ctxPath=/jmx-console, warUrl=.../deploy/jmx-console.war/ 2012-11-08 16:09:51,664 ERROR [org.jboss.deployment.scanner.URLDeploymentScanner] Incomplete Deployment listing: --- Incompletely deployed packages --- org.jboss.deployment.DeploymentInfo@5cc18807 { url=file:/usr/local/JBoss/jboss-4.2.2.GA/server/default/deploy/xxxxx-1.0.war } deployer: MBeanProxyExt[jboss.web:service=WebServer] status: Deployment FAILED reason: Error during deploy; - nested throwable: (javax.management.ReflectionException: Cannot find setter method setLoader StandardContext[null]) state: FAILED watch: file:/usr/local/JBoss/jboss-4.2.2.GA/server/default/deploy/xxxxx-1.0.war altDD: null lastDeployed: 1352390987263 lastModified: 1352390987000 mbeans: --- MBeans waiting for other MBeans --- ObjectName: jboss.web.deployment:war=xxxxx-1.0.war,id=1556187143 State: FAILED Reason: org.jboss.deployment.DeploymentException: Error during deploy; - nested throwable: (javax.management.ReflectionException: Cannot find setter method setLoader StandardContext[null]) --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM --- ObjectName: jboss.web.deployment:war=xxxxx-1.0.war,id=1556187143 State: FAILED Reason: org.jboss.deployment.DeploymentException: Error during deploy; - nested throwable: (javax.management.ReflectionException: Cannot find setter method setLoader StandardContext[null])So am thinking it's a collision between a catalina class in a lib in the war, and one already in jboss? As it worked ok when it was 1.3.6, is it something that's been added to the 2.1.1 grails tomcat plugin and is it possible to exclude a sub-dependency from a grails plugin?
Thanks.

'0' + rem没有按你的想法做：'0'是char字面值，rem是int值。 将它们一起添加将产生一个int，表示ASCII值为'0'或'1'。更多信息： “将int转换为ASCII字符”
'0' + remis not doing what you think:'0'is acharliteral andremis anintvalue. Adding them together will result in anintthat represents the ASCII value of either'0'or'1'.More information: "Convert an int to ASCII character"

首先，您使用=进行比较测试。 相反，我认为你想使用!= （不等于）： while n != 1: =仅用于分配。 另外，该行： n/10 什么也没做。 相反，它应该是： n /= 10 这相当于： n = n / 10 First of all, you used = for a comparison test.
