Hello
I want to write a portlet for Jetspeed2. This portlet should display a given html page. Let's call this portlet HtmlPortlet. I want to put 4 portlets on my page, each of them should display a given page.
++++++++++++++++++++++++++++++++++++++++++++++ | | | | | | | HtmlPortlet | HtmlPortlet | | | | | displays a.html | displays b.html | | | | | | | ++++++++++++++++++++++++++++++++++++++++++++++ | | | | | | | HtmlPortlet | HtmlPortlet | | | | | displays c.html | displays d.html | | | | | | | ++++++++++++++++++++++++++++++++++++++++++++++
Does anybody know how to set an "myUrl" property of these portlets? Is it possible? I know that properties of portlets are stored in database, but I would like to set the property "myUrl" in a file. If it is impossible, maybe you know how to make my application to set this property in database for each portlet.
Regards Marek
Think you mean preferences.
The storage method of preferences is up to the portal impl.
You shouldn't really be concerned with the details of how the portal stores preferences...
Are you looking for an external link or a local file? We already have a web content portlet for external links in Jetspeed-2.
For a local html file, I just took 5 minutes and wrote this portlet for you.
I guess I should commit it to Gems if Ken doesnt already have something like this.
