Hello,
I have a quick question on the JetExpress tutorial, which I find
very useful, since I'm new to both Jetspeed and the portlet
development.
In the "05. Jetspeed Services" section, there is a code snippet
after the line "Enter the following code into the init(PortletConfig
config) method, replacing whats there:". I think there should be a
call made to super.init(config) in the beginning of that snippet,
but am I correct?
Without this call, I get "Failed to load portlet
com.bluesunrise.portal.portlets.services.ServicesTutorialPortlet:
java.lang.NullPointerException" message in the portlet window
fragment.
Thanks
By the way, at the end of that section, the tutorial instructs me to
implement the undefined methods, but I wasn't quite clear on how to
implement modifyPages(). I looked into the API document, but still
can't figure out how.
Can you give me a pointer to further information on how to use
Jetspeed Services?
Well its supposed to be an exercise, but I can give you a solution if
you want
I have a real solution but its on my other computer that is on loan
right now
This is one I just wrote without testing, its not exactly complete
but should give you the general idea
private String modifyPages()
{
// using the users init param, modify pages with the
PageManager service.
// If the page doesnt exist, dont create it. Modifications:
for user1, create a 1 column collection of 1 portlet,
// for user2, create a 2 column collection of 2 portlets,
for user3 create a 3 column collection of 3 portets
int count = 0;
Iterator users = this.newUsers.iterator();
while (users.hasNext())
{
String username = (String)users.next();
try
{
if (!pageManager.folderExists(Folder.USER_FOLDER +
username))
{
Folder folder = pageManager.newFolder
(Folder.USER_FOLDER + username);
folder.setTitle("Home");
pageManager.updateFolder(folder);
Page page = pageManager.newPage
(Folder.USER_FOLDER + username + Folder.PATH_SEPARATOR + "home.psml");
Fragment root = pageManager.newFragment();
root.setName("jetspeed-
layouts::VelocityOneColumn");
Fragment portlet = pageManager.newPortletFragment
();
portlet.setName("app::portletname");
root.getFragments().add(portlet);
page.setRootFragment(root);
pageManager.updatePage(page);
count++;
}
}
catch (Exception e)
{
// ....
break;
}
}
...
