Hi colleagues! I need some help for the Scheduler. I already have some not small script in a velocity. This script select some pages with complex conditions (hql), make some calculations and sending emails. Now this script is working when I simply open it page (where script is placed). I need to make automatic schedule for this script (for example - every day). Unfortunately, scheduler scripts permit only groovy scripts ... Also, problem for me - I dont't now groovy at all (velocity - so-so) and I am not a programmer. For me - groovy learning is difficult (in any case - not quickly). My question - is any possibility to use my velocity script without total rewriting for groovy? Maybe I can write groovy script with redirection for my page with velocity script? Maybe is it possible to include code of one scripting language in another? If is not (only need to totally rewrite script to grovvy) can somebody can help me in this operation? I attached my original velocity script (it's working fine). http://xwiki.475771.n2.nabble.com/file/n5666438/velocity_script.txt velocity_script.txt -- Thanks beforehand Eugen Colesnicov -- View this message in context: http://xwiki.475771.n2.nabble.com/Using-Scheduler-issues-groovy-questions-t… Sent from the XWiki- Users mailing list archive at Nabble.com.

My first hint would be to consider groovy as java. It's not exactly the same but it shares most. The other idea is to simply call the web page from groovy? new java.net.URL("blablalba").getContent() paul On 23 oct. 2010, at 23:26, Eugen Colesnicov wrote:

I tried redirecting in a scheduler script. I wrote: {{groovy}} response.sendRedirect(xwiki.getURL("ETVCCorrespondenceCode.CronJobProgrammingCode")); {{/groovy}} After this I started to using scheduler. First, I tried to trigger my job (as I understand - this button starts execution of script immediately). This give me error: Error number 90012 in 5: com.xpn.xwiki.plugin.scheduler.SchedulerPlugin: Error occured while trying to trigger job ETVCCorrespondenceJob Wrapped Exception: The job (DEFAULT.xwiki:Scheduler.ETVCCorrespondenceJob_0) referenced by the trigger does not exist. Looks like program cannot find job ETVCCorrespondenceJob_0 - but my job named ETVCCorrespondenceJob without "_0". what is "_0" - I don't know. I tried to rename my job to ETVCCorrespondenceJob_0 - but also give me error but with ETVCCorrespondenceJob_0_0 ... I cannot understand this error. This error exists also, if I write ANY script (also empty script field). Ok ... I tried to schedule my job. I putted small interval (30 seconds) - I don't see any results (no emails in my mailbox) - but computer processor gets high CPU (100%). I saw - java process giving this. I restarted my ApplicationServer (Glassfish) - all is ok for the next time, when I tried to schedule my job for 30 seconds interval. No any errors or special message in a logs ... I am not a professional in these and I cannot understand - this is my problem (maybe I doing something wrong) or is it bugs? -- View this message in context: http://xwiki.475771.n2.nabble.com/Using-Scheduler-issues-groovy-questions-t… Sent from the XWiki- Users mailing list archive at Nabble.com.

You can't redirect a scheduled job. Redirects affect HTTP responses only, and a job executes without a valid request/response pair.

Yes, but note that the URL will be fetched without any session information, so if the requested page is private (not visible for guests), it won't work. -- Sergiu Dumitriu http://purl.org/net/sergiu/

Paul, can you give exactly example? What I should write in a scheduler field - "Job script"? Because of I tried different variants - but without results. Also, I rewrited my original code from velocity to groovy. I tested my groovy rewrited code in a another xwiki page - all is working fine. But when I putted this groovy code to the scheduler - no any actions. Looks like, that scheduler don't work at all, but standart xwiki watchlists - working ... I cannot understand nothing. Maybe somebody can help me. I attached my groovy code (as I said - from another xwiki page - this code working fine). http://xwiki.475771.n2.nabble.com/file/n5667864/groovy_code.txt groovy_code.txt Also, my original question (how need to call velocity code from groovy code in a scheduler) also is interesting for me.

Could be not a script problem at all. If you test the scheduler via triggering, you need to unschedule, then reschedule, then trigger the job.

I made like you said - no result. Also I really waiting for scheduled time - also no result. But another bad thing - after this (manually triggered or automatically triggered the job) the CPU for the JAVA process goes to 100%. No any logs in a jvm or application logs ... - all look like as normal. My config - Windows, Oracle10G, Glassfish 3.01, XWiki Enterprise 2.4. What it can be?

I found what is it!!! I am writing groovy code in a job page with {{groovy}} at the beginning and {{/groovy}} at the end of script. If I do like this - process JAVA.EXE goes to 100%. I simply deleted {{groovy}} and {{/groovy}} and my full groovy script, which I rewritted from my original velocity and pasted in a scheduler job page - started to work. Also I checked this 100% processor using variant at another machine, with another configuration - same situation. Very strange, but I think need to make some notes in a scheduler - that users shouldn't use {{groovy}} at the beginning and {{/groovy}} at the end of script. But, calling velocity or groovy script from scheduler script doesn't work ... I think, I wrote something wrong. Can somebody give me exactly example?

I don't think so. But I note that I'm using an older xwiki. Could be that they disabled that in more modern ones because it's not a good practice

the scheme there isn't the same. paul

Eugen, you said you have a velocity page, say accessible at http://server/xwiki/bin/iview/MyScheduler/Velo what I was telling is that you should be able to get its execution from groovy with new URL("http://server/xwiki/bin/iview/MyScheduler/Velo").getContent() and, if you needed secure access for that execution you could request new URL("http://admin:psps@server/xwiki/bin/iview/MyScheduler/Velo").getContent() provided the user admin has password psps. paul On 24 oct. 2010, at 17:13, Eugen Colesnicov wrote:

Great! All is working! Without pass - is working too.
