[Building Sakai] Very basic velocity question: parsing data from java to template in Sakai

[David Wafula Wanyonyi]

Thanks all. Took me a while, but turned out the jar file was not being deployed correctly. All is good now.
Regards.

Lose the curly braces, you don't need them in this instance, you only need them if the variable name was actually part of another sentence. Also, if the variable isn't set, then Velocity outputs the variable name in its entirety. You can disable that by printing it as:

$!passwordExpireMessage

and it will be blank.

And thats what you are getting (the var name being printed because the contents are not set), so I would be checking that where you set the variable in the Java class, is the correct spot.

So what I would end us with is:

<span class="pawword-expire-warning">
$passwordExpireMessage
</span>

Once you have it working, then internationalise with the resource loader and the properties file. Don't introduce that complexity just yet ;)

cheers,

Steve

I'm not sure, it works for me. You're redeploying the webapp with the new war, and new source code from that java file, right? I'd make 100% that your variable names match up, in your span class it says pawword-expire-warning, making me think you might have had a typo.

Though what you *really* want to do for something like this is put it in
portal-impl/impl/src/bundle/sitenav.properties

pwd_expire_msg = Some message about expiration

And use the ResourceLoader, which for portal looks like it is

${rloader.pwd_expire_msg}

Hi all,
Never used velocity before, so my first attempt is not going any where; please point me where am getting it wrong:

in   https://source.sakaiproject.org/svn/portal/tags/portal-base-2.9.2/portal-impl/impl/src/java/org/sakaiproject/portal/charon/SkinnableCharonPortal.java,


there is  includeLogin(),  with lines:
....
  rcontext.put("loginLogInOutUrl", logInOutUrl);
  rcontext.put("loginMessage", message);
.......

so am adding something simple:

 String pwdMessage = "Warning: Your password is expiring in 6 days";
  rcontext.put("passwordExpireMessage", pwdMessage);


I go to includeTabs.vm:

<span class="pawword-expire-warning">
${passwordExpireMessage}
</span>

it prints '${passwordExpireMessage}' instead of actual message


if i try and replace this with say ${loginMessage}, just for testing, the correct message is printed.



The trick ?
Thanks.
