[xwiki-users] Groovy Notification Tutorial
Hello everyone, In the Groovy Notification Tutorial (http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial), there is a field source that is an Object. To have the full name of the source, we have to write : source.fullName. For what I'm doing, I just want to have the space of the source. I've tried different things, but no one seems to work. Do you have an idea of how I can have only the space of the source ?

Re: [xwiki-users] Groovy Notification Tutorial
source is an XWikiDocument (inner document of a Document from XWiki api) as can be seen here, in the sample : http://extensions.xwiki.org/xwiki/bin/view/Extension/Observation+Module+Local I think source.space might work (was deprecated, didn't check if it's still there). Or something like source.getDocumentReference().getLastSpaceReference().getName() Jerem 2012/6/4 Stéphanie stephanie.roull...@gmail.com: Hello everyone, In the Groovy Notification Tutorial (http://platform.xwiki.org/xwiki/bin/view/DevGuide/GroovyNotificationTutorial), there is a field source that is an Object.

the test for the change coming from a space's Blog so that any

Still no joy.
The only clue in the log is when calling the notify method from a
velocity script:
[WARNING] Cannot retrieve method notify from object of class
BlogMailNotificationGroovyClass due to security restrictions.
This looks to me very likely to be linked with the security
configuration of the servlet container.
In which environment does your wiki run in ?

Ok, I have another idea. Did you try sending the mail without
attachments ?
This because what you pass the plugin API are XWikiAttachments
(http://maven.xwiki.org/site/xwiki-core-parent/xwiki-core/apidocs/com/xpn/xwiki/doc/XWikiAttachment.html
),
while it expects com.xpn.xwiki.api.Attachment (see the plugin API
here
http://code.xwiki.org/xwiki/bin/view/Plugins/MailSenderPlugin).
If you want to have the proper wrapped attachments to pass the plugin,
you should use newdoc.newDocument(context).getAttachmentList()
Hope this helps,
Jerome.

It is probably due to the following :
if(newdoc.getSpace().substring(lastFour) == Blog) {
in Java, if you have the following :
String st1 = Blog;
String st2 = new String(Blog);
then st1 == st2 will always return false, as the objects are not the
same. What you want is to compare their values, using
st1.equals(st2),
which will return true.
You can read here to find out more
http://www.unix.com.ua/orelly/java/langref/ch04_09.htm (especially
this
sentence : Because the == operator determines if two objects are
the
same object, it is not appropriate for comparisons that need to
determine if two objects have the same contents. For example, if you
need to know whether two String objects contain the same sequences
of
characters, the == operator is inappropriate. You should use the
equals() method)
Anyway, their is even simpler for you. What you want to do is
check if
the space name finishes by Blog. For this the appropriate method
is
String#endsWith
(http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#endsWith(java.lang.String

I believe those logs are generated when you call

Re: [xwiki-users] groovy notification
It is probably due to the following :
if(newdoc.getSpace().substring(lastFour) == Blog) {
in Java, if you have the following :
String st1 = Blog;
String st2 = new String(Blog);
then st1 == st2 will always return false, as the objects are not the
same. What you want is to compare their values, using st1.equals(st2),
which will return true.
You can read here to find out more
http://www.unix.com.ua/orelly/java/langref/ch04_09.htm (especially this
sentence : Because the == operator determines if two objects are the
same object, it is not appropriate for comparisons that need to
determine if two objects have the same contents. For example, if you
need to know whether two String objects contain the same sequences of
characters, the == operator is inappropriate. You should use the
equals() method)
Anyway, their is even simpler for you. What you want to do is check if
the space name finishes by Blog. For this the appropriate method is
String#endsWith
(http://java.sun.com/j2se/1.4.2/docs/api/java/lang/String.html#endsWith(java.lang.String))
As in :
if(newdoc.getSpace().endsWith(Blog)) {

From what I understand, when using new we deliberately state that the
String should not be interned, thus the object are not going to be the
same any case.
Strings can be automatically interned by the JVM (without calling
.intern()) only when initialized not using new :
String st1 = Blog;
String st2 = Blog;
and then can potentially be considered as same.
Anyway, I'm discovering this :) I read that from

There's even an intern() method to force your string content to be

[ERROR] Left side ($index) of addition operation has null value.
Operation not possible. [line 20, column 25]
The number of lines corresponds to the number of comments present in
the Blog article. There's nothing in the log pertaining to the groovy
class.
Indeed, this has nothing to do with your groovy notification. This is
generated by the velocity engine.
Is your skin customized ? Is the blog application modified ? (The log
says that somewhere a variable $index is trying to add something to
null. Might be the pagination of blog articles ?)
Jerome.
I can't find a variable $index in any arithmetical expression in any
velocity script anywhere on the site.

Re: [xwiki-users] groovy notification
Do you actually encounter a problem, besides the error in the logs ?
I believe those logs are generated when you call getRenderedContent on
your blog article, so I maintain they have nothing to do with your
notification class.
Which version of XWiki Enterprise are you using ?
Jerome.

Hi,
I'm trying to use the notification system to trigger the sending of
email whenever a comment is added to a blog article. I'm patterning my
groovy class after the pircbot example on the xwiki snippets site.
My system is xwiki workspaces as a virtual xwiki under xem. The
platform version is 1.5.2.
Here's my groovy class (XWSNotify.BlogMailNotificationGroovyClass):
/* Groovy Class #* */
import com.xpn.xwiki.api.XWiki;
import com.xpn.xwiki.XWikiContext;
import com.xpn.xwiki.notify.XWikiDocChangeNotificationInterface;
import com.xpn.xwiki.notify.DocObjectChangedRule;
import com.xpn.xwiki.notify.XWikiNotificationRule;
import com.xpn.xwiki.doc.XWikiDocument;
public class BlogMailNotificationGroovyClass implements \
XWikiDocChangeNotificationInterface
{
def xwiki;
def rule;
def name;
public void initClasses(XWikiContext context)
{
this.xwiki = context.getWiki();
// listen to notifications
this.rule = DocObjectChangedRule(this);
context.getWiki().getNotificationManager().addGeneralRule(rule);
}
public void notify(XWikiNotificationRule rule, XWikiDocument
newdoc, \
XWikiDocument olddoc, int event, XWikiContext
context)
{
def length = newdoc.getSpace().length();
def lastFour = length - 4;
if(newdoc.getSpace().substring(lastFour) == Blog) {
def ms = xwiki.getPlugin(mailsender);
def nb = ms.sendHtmlMessage(context.getUser(),
[EMAIL PROTECTED] mailto:[EMAIL PROTECTED]
, \
context.get(ccrecipients),
context.get(bccrecipients), \
context.get(subject),
newdoc.getRenderedContent(), \
newdoc.getContent(),
newdoc.getAttachments());
}
}
}
/* *# */
Here's a velocity script I'm using to initialize/test:
#set($sc = $context.getContext().getEngineContext().getServletContext())
$sc.getAttribute(blgmailnotif)br/
#set($blgmlnotif =
$xwiki.parseGroovyFromPage(XWSNotify.BlogMailNotificationGroovyClass))
#set($ok = $sc.setAttribute(blgmailnotif, $blgmlnotif))
#set($blgmailnotif = $sc.getAttribute(blgmailnotif))
$sc.getAttribute(blgmailnotif)br/
#set($ok = $blgmlnotif.initClasses($context))
#set($ok = $blgmlnotif.notify($blgmlnotif.rule,$newdoc,$newdoc,
3,$context))
Here's the output from the velocity script:
[EMAIL PROTECTED]
[EMAIL PROTECTED]
So, the groovy class gets initialized to a new reference successfully
each time parseGroovyFromPage is called.
Here's what appears in the log after running the velocity script:
[ERROR] Left side ($request.title) of '!=' operation has null value.
Operation not possible. [line 53, column 43]
[WARNING] Cannot retrieve method notify from object of class
BlogMailNotificationGroovyClass due to security restrictions.
If I alter the velocity script to:
#set($sc = $context.getContext().getEngineContext().getServletContext())
$sc.getAttribute(blgmailnotif)br/
Here's what appears in the log:
[ERROR] Left side ($request.title) of '!=' operation has null value.
Operation not possible. [line 53, column 43]
So, the [WARNING] is the only log entry pertaining to the groovy class.
If I add a comment to a Blog article (with or without the
BlogMailNotificationGroovyClass initialized), the following appears in
the log:
[ERROR] Left side ($index) of addition operation has null value.
Operation not possible. [line 20, column 25]
