问题 Using grails 2.4.2, quartz:1.0.2, I'm trying to gain access to configuration properties class MyJob { def grailsApplication int propA def MyJob() { propA = grailsApplication.config.foo.bar.propAVal } ... } grailsApplication, however, doesn't get injected, and is null.

问题 I want to develop a simple Java Web app to send an email notifications after some task is done, such as a request submitted for approval, and reminders (to say approvers) at regular intervals. I want to do this using the Quartz Scheduler. I am a newbie, so can anyone help me to start on this. Thanks in Advance. I copy and pasted the JAR file : quartz-1.8.0 in WEB-INF\lib and even in common\lib, then it is not found while importing in my Java file. :( 回答1: Create a servlet that starts at web

问题 I can use dynamic finders on my domain classes in my Quartz job, but get org.hibernate.LazyInitializationException when accessing relationships. I thought they would either both work, or none. class MyJob { def author = Author.list().first() // fine def book = Book.get(1) // fine println author.books // lazy exception } Any idea why this might be happening? According to the Quartz plugin documentation each job thread gets a Hibernate session, yet I'm running into this problem. Grails 2.1.1 ,

问题 I am creating an application that uses Quartz.NET, which is utilised within a Windows service. There is also an administration backend written in ASP.NET, where administrators can add jobs and monitor the state of the scheduler. I am however having issues with the ASP.NET backend. The connection is made in the Global.asax file, which seems to work at first - when the user logs on to the main dashboard, it works fine. The problem is when the user clicks onto a different page, where it then

问题 I am trying to configure my Quartz scheduler to support logging. I had tried doing following: Added log4j.xml in classes folder of my app. The code for the same is: log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.Target=System.out log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern= %d{ABSOLUTE} %5p %c{1}:%L - %m%n log4j.rootLogger=debug, stdout Added following statements in my scheduler class: static Logger

问题 I am exploring on quartz scheduler, What are the differences between Cron trigger and Simple trigger except for how they are being defined. I dint find any other differences. like which is thread safe or which is said as best practice or anything like that. can someone explain what are the differences between them and at what scenarios we could use them 回答1: The differences between the two are merely how you wish to schedule the execution of your jobs. There are no other differences in terms

问题 Scenario: I have a console application that needs to access a network share with read/write permissions. There is no problems when run it manually. The problem: When I add this application as a job in my quartz.net server, it cannot access the share. I do not have access to change permissions on the network share, so basically I need my quartz job or if necessary my quartz server to run jobs as me (or as a user that has the proper permissions). Any ideas in how to accomplish this? Thanks 回答1:

问题 Is it possible using the Quartz .NET assembly to generate a cron expression? I saw that the CronScheduleBuilder class has a private member cronExpression which is essentially what I am looking for. Is there any other way to get the cron expression itself? 回答1: Possible using ICronTrigger.CronExpressionString CronScheduleBuilder csb = CronScheduleBuilder .WeeklyOnDayAndHourAndMinute(DayOfWeek.Monday, 12, 0); ICronTrigger trigger = (ICronTrigger)TriggerBuilder .Create() .WithSchedule(csb)

问题 guys, I have monthly jobs scheduled(using Quartz) by users. Users provide starting date f or first job to run, it could be any day of month 1-31 My question is how to schedule this using cron trigger, having in mind that not all month have 31,30,29th days. In such case job should run closest previous day of the month. So, lets say April has only 30 days, so job has to run on 30th of April. Can it be done using single cron trigger? Or should it be combination of triggers? I tried to play with
