How to set environment variable and read it using .vm

[Dmitry Brin, módosítva 13 év-val korábban]

Hi,
I am looking for a simple way to set an environment variable at portal instance level (set it once) and read it in using VM template (init.vm actually) I don't want to use URL mappings as those can change.

Thanks for any suggestions,
Dmitry.

Hi,

This link might help you - Custom Velocity Variables

To check existing variables refer to class VelocityVariables.java

Thanks for the suggestion. Isn't there a way to read it from a properties file like ext-portal.properties using propUtil?

You can use propsUtil to read from properties file in VM.
Something like this - $propsUtil.get("keyName").

Refer to the link - Access Object from a Velocity Template

Tina, I was able to use you suggestion. Here is what I had to do:

on the portal_normal.vm I added

$propsUtil.get("my.special.url")

to source the property stored in myspecial.properties file.

In order for Liferay to read my properties file I added this line

include-and-override=portal-instance.properties, myspecial.properties

to the portal-ext.properties .

This allows me to add and read properties at the portal level without modifying the install.

Hi Tina and all,

Thank you all for useful information.
But please let me know how to implement the scenario like-
I want to create a properties file (say test.properties) inside theme plugin and define variables inside it.
so how to read this properties file in vm template file?
and in which folder should I create this properties file?

Thanks,
Himanshu

Hi Dmitry,

It's look to me that $propsUtil.get("xxx") only read the properties declared in portal-ext.properties :/
I try to use this mecanism but it doesn't work ..

If i try to call $propsUtil.get("my.special.url") only present in myspecial.properties, liferay displaying $propsUtil.get("my.special.url") but when i write my.special.url property in portal-ext, $propsUtil.get("my.special.url") displaying the right value ..
