javax.ejb.EJBException:JBAS014516:无法在org.jboss.as.ejb3.component的org.jboss.as.ejb3.pool.strictmax.StrictMaxPool.get(StrictMaxPool.java:109)的5分钟内获取许可证. org.jboss.as.ejb3.remote.EJBRemoteTransactionPropagatingInterceptor.processInvocation(EJBRemoteTransactionPropagatingInterceptor.java:8 0)中的org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)中的pool.PooledInstanceInterceptor.processInvocation(PooledInstanceInterceptor.java:47) )在org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)在org.jboss.as.ejb3.component.interceptors.CurrentInvocationContextInterceptor.processInvocation(CurrentInvocationContextInterceptor.java:41)在org.jboss.invocation.InterceptorContext.在org.jboss.as.ejb3.component.interceptors.LoggingInterceptor.processInvocation(LoggingInterceptor.java:59)在org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)进行(InterceptorContext.java:288)在组织.jboss .as.ee.component.NamespaceContextInterceptor.processInvocation(NamespaceContextInterceptor.java:50)在org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)在org.jboss.as.ejb3.component.interceptors.AdditionalSetupInterceptor.processInvocation org.jboss.invocation.InterceptorContext.proceed(InterceptorContext.java:288)org.jboss上的org.jboss.as.ee.component.TCCLInterceptor.processInvocation(TCCLInterceptor.java:45)中的(AdditionalSetupInterceptor.java:32).在org.jboss.as.ee.component.View的org.jboss.invocation.ChainedInterceptor.processInvocation(ChainedInterceptor.java:61)中的invocation.InterceptorContext.proceed(InterceptorContext.java:288)$ View.invoke(ViewService.java: 165)在org.jboss.as.ejb3.remote.LocalEjbReceiver.processInvocation(LocalEjbReceiver.java:179)在org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:179)在org.jboss.ejb.client .TransactionInterceptor.handleInvocation(TransactionInterceptor.java:4 3)在org.jboss.ejb.client.EJBClientInvocationContext.sendRequest(EJBClientInvocationContext.java:181)在org.jboss.ejb.client.ReceiverInterceptor.handleInvocation(ReceiverInterceptor.java:128)在org.jboss.ejb.client.EJBClientInvocationContext .sendRequest(EJBClientInvocationContext.java:181)在org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:136)在org.jboss.ejb.client.EJBInvocationHandler.doInvoke(EJBInvocationHandler.java:121)在有机jboss.ejb.client.EJBInvocationHandler.invoke(EJBInvocationHandler.java:104)

我有两个表,我正在做一个完整的外连接.表有一个时间戳列.我希望通过时间戳排序连接的结果.比如表a有行

表A.
