How to get parameter's value from URL in Gatein Portlet?

[terry.lin]

Hi all,

Is there any way to get parameter's value form URL in Gatein Portlet?

ex: http://localhost:8080/portal/myapp/search?id=234

how can i get 「id」 value ？

thanks.

Hello,

Portlets specification doesn't define how URL are managed. It's part of

portal implementation.

Having said that, your "id" parameters should be visible from action phase

but not from render phase.

In master we are patching this to allow to get also public render

parameters from URL:

https://github.com/gatein/gatein-portal/commit/51456e416e717a10b2a0a6410d0019468228a327

Meanwhile you can use two workarounds:

- One can be to import private packages of gatein and get the underlying

HttpRequest object.

- Other can be to access to PortalRequest object and maps your parameter in

the path like a "rest-style" parameter

http://localhost:8080/portal/lipc_patent/ptSearch?id=234

should be http://localhost:8080/portal/lipc_patent/ptSearch/id/234

and then you can access full path using public gatein api:

        PortalRequest pRequest = PortalRequest.getInstance();

        String path = pRequest.getNodePath().toString();

I have an example here:

*https://github.com/lucasponce/gatein-wcm/blob/master/wcm/src/main/java/org/gatein/wcm/portlet/content/render/RenderActions.java#L538

<https://github.com/lucasponce/gatein-wcm/blob/master/wcm/src/main/java/org/gatein/wcm/portlet/content/render/RenderActions.java#L538>*

*But as I said, in gatein master, the patch for Public Render

Parameters from URL allows to perform this functionality.*

Hope this helps,

Lucas
