Hi Marthias,<div><br></div><div>In documentation, you see the method:</div><div><span style="color:rgb(153,153,136);font-family:Consolas,'Liberation Mono',Courier,monospace;font-size:12px;font-style:italic;line-height:16px;white-space:pre;background-color:rgb(255,255,255)">// site roots must never end with a "/"</span> </div>

<div><span style="font-family:'courier new',monospace;font-size:x-small"><br></span></div><div>Good luck,</div><div><br></div><div>Deiverson</div><div><br></div><div><br><div class="gmail_quote">2012/7/13 Mathias Lin <span dir="ltr"><<a href="mailto:mail@mathiaslin.com" target="_blank">mail@mathiaslin.com</a>></span><br>
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I try to create a scheduled job, which worked fine so far when I created it manually, in code. Idea is that I want the scheduled job to be created automatically when a module is being imported and initialized, using the Module Action class. (OpenCms 8.0.3)<div>
<br></div><div>The problem that I encounter though is that the programmatically created scheduled job appears fine in the Opencms workplace / job administration. And the configuration of all it's fields looks exactly the same in the OpenCms workplace admin.</div>
<div>Here's a screenshot of the config: <a href="http://imageshack.us/photo/my-images/10/ocmsjobconfig.jpg/" target="_blank">http://imageshack.us/photo/my-images/10/ocmsjobconfig.jpg/</a></div><div><br></div><div>But: it throws some exception when it's being executed (NullPointer on OpenCms core code level), and also I cannot modify the job anymore. When I try to modify the job via OpenCms workplace, I get some error message ("The following errors occurred when validating the form: Adding text to an XML document must not be null"); marked red in the screenshot above.</div>

<div><br></div><div>I noticed the following problems:</div><div><br></div><div>1) As you can see in my comment in my code above, I tried to set the siteRoot of the contextInfo to something other than null, i.e. "/" or some other path, but this is not reflected in the OpenCms workplace / admin section when looking into the job configuration after it's been created. The siteRoot field will always remain empty there, regardless of what I had put in my code, which created the job.</div>
<div><br></div><div>2) I cannot modify the job in the workplace after it's automatic creation. I get an error "The following errors occurred when validating the form: Adding text to an XML document must not be null", as shown in above screenshot.</div>
<div>When I hit the 'save' button a second time, I get a detailed log which shows me the following error message - which actually makes me wonder: where are the scheduled jobs stored actually? I couldn't find them in the DB nor in any of the config files.</div>
