Hi Guys

Hoping one of you can help me out, im new to liferay and JAVA, i'm vb.net normally but after finding liferay by chance i love it and its much better than .net nuke out of the box (in my opinion) anyway ive been able to use the help articles and learnt some cool stuff so far, but now im stuck.

I have many organisations in my company and what id like to do is is redirect them to the organsation landing page when they login depending on what organisations they belong to. (in some isntances it could be many i know but ill handle that with an if statement)

I have seen this post but its left me with some questions. post

1) Am i right in thinking that i just need to update the code here in notepad and save it?
portal-impl/src/com/liferay/portal/events/DefaultLandingPageAction.java
2)How can i get the organisation the user belongs to programmatically
3)How would i structure the if statment to determine where to redirect them to, for example in vb.net i could do it like

If user.organisation = "Business" then
Response.redirect("blabala"

Any help would be greatly appreciated as im alittle stuck on what to update where, and what code i need to actually achieve the desired result

Thanks in advance

Dan

There are two steps involved here -

1) If a user has to access an organization , user should belong to that organization
there are two ways to do that -


2) Redirecting user to respective organization .
You can achieve this by writing your code in DefaultLandingPageAction.java

Now to your questions -

1) Am i right in thinking that i just need to update the code here in notepad and save it?
portal-impl/src/com/liferay/portal/events/DefaultLandingPageAction.java

If you are building directly from source code , you can do the way you mentioned . Otherwise you have to add DefaultLandingPageAction.java to you ext code in following directory ext-impl/src/com/liferay/portal/events/DefaultLandingPageAction.java


2)How can i get the organisation the user belongs to programmatically

User this code to fetch User's Organization


You can iterate through this list to find all the organization user belongs to.

3)How would i structure the if statment to determine where to redirect them to, for example in vb.net i could do it like

Here is the sample code to redirect the User based on Organzation - It will go inside run() method of DefaultLandingPageAction.java


Hope this helps

Thanks
Arvind

Hi Arvind

Thanks so much for your help so far, but i have a few more questions.

I am using netbeans and have downloaded the source code for liferay, i have copied the file DefaultLandingPageAction.JAVA and renamed it CustomLandingPageAction.JAVA

I have written this code so far:

public class CustomLandingPageAction extends Action {

public void run(HttpServletRequest request, HttpServletResponse response) {
String userId = request.getRemoteUser();
User user = UserLocalServiceUtil.getUserById(Long.parseLong(userId));
List<Organization> userOrganizations = null;
userOrganizations = OrganizationLocalServiceUtil.getUserOrganizations(Long.parseLong(userId));

Is this correct so far? as i am getting an error message "unreported exception com.liferay.portal.PortalException; must be caught or declared to be thrown

I am not quite sure what this means, can you advise.

Thanks in advance.

Because the methods in LocalServiceUtils throw this exceptions .
You can handle them like this

Hi Arvind

Thanks for all your help, I came up with this, was going to let you know, i realised i needed a try catch block after doing some searching online, does this code look right to you?

Hi Dan

Code is fine . But there is one thing . Although you have declared the "user" variable , you are not using it any where. But later on if you want to use this variable you have to change your code .



Thanks
Arvind

Hi Arvind

Thanks for pointing that out, ill change it now, 1 more piece of advice if you wouldnt mind,

I am running the liferay tomcat bundle. not from source code, i have also downloaded th source which i am opening with netbeans ide. I have created the code in the liferay source within netbeans ide.

How can i now get this inside the tomcat bundle, do i do one of the following:

1) Simply copy my JAVA file and paste it inside the current tomcat bundle jar file
C:\liferay-portal-5.2.3\tomcat-6.0.18\webapps\ROOT\WEB-INF\lib\portal-impl
2) do i need to compile the file or build it or something like this
3) do i need to complie all my Liferay source code and then take the compiled JAR of C:\liferay-portal-5.2.3\tomcat-6.0.18\webapps\ROOT\WEB-INF\lib\portal-impl and put this inside my liferay tomcat bundle?

Can you advise, im alittle confused as i havent done this before.

Thanks in advance.

You need to compile source code and place portal-impl.jar inside webapps\ROOT\WEB-INF\lib

thanks
Arvind

Hi Arvind

That worked, and it compiled fine, however the code doesnt seem to work, once i login it comes up with a html page cannot be displayed message.

I have tried this code,

public class CustomLandingPageAction extends Action {

public void run(HttpServletRequest request, HttpServletResponse response) {

String userId = request.getRemoteUser();
String forwardUrl = "";
User user = null;
try
{
user = UserLocalServiceUtil.getUserById(Long.parseLong(userId));
}
catch (PortalException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
catch (SystemException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
List organizations = null;
try
{
organizations = OrganizationLocalServiceUtil.getUserOrganizations(Long.parseLong(userId));
}
catch (SystemException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
for (int i = 0; i < organizations.size(); i++)
{
Organization organization = (Organization) organizations.get(i);

}
if (organizations.contains("Consumer")){
forwardUrl = "web/consumer";
}
else if (organizations.contains("Business")){
forwardUrl = "web/business";
}
else if (organizations.contains("Team Leader")){
forwardUrl = "web/teamleader";
}
else if (organizations.contains("Technical")){
forwardUrl = "web/technical";
}
else
{
forwardUrl = "web/consumer";
}

if(forwardUrl !=null && !forwardUrl.equals(StringPool.BLANK)){
LastPath lastPath = new LastPath(StringPool.BLANK, forwardUrl , new HashMap<String, String[]>());

HttpSession session = request.getSession();
session.setAttribute(WebKeys.LAST_PATH, lastPath);
}
}
}
And also this

public class CustomLandingPageAction2 extends Action {

public void run(HttpServletRequest request, HttpServletResponse response) {

String userId = request.getRemoteUser();
String forwardUrl = "";
User user = null;
try
{
user = UserLocalServiceUtil.getUserById(Long.parseLong(userId));
}
catch (PortalException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
catch (SystemException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
List organizations = null;
try
{
organizations = OrganizationLocalServiceUtil.getUserOrganizations(Long.parseLong(userId));
}
catch (SystemException ex)
{
Logger.getLogger(CustomLandingPageAction.class.getName()).log(Level.SEVERE, null, ex);
}
for (int i = 0; i < organizations.size(); i++)
{
Organization organization = (Organization) organizations.get(i);

}
if (organizations.contains("Consumer")){
forwardUrl = "/web/consumer/home";
}
else if (organizations.contains("Business")){
forwardUrl = "/web/business/home";
}
else if (organizations.contains("Team Leader")){
forwardUrl = "/web/teamleader/home";
}
else if (organizations.contains("Technical")){
forwardUrl = "/web/technical/home";
}
else if (organizations.contains("Sales")){
forwardUrl = "/web/sales/home";
}
else
{
forwardUrl = "web/consumer/home";

}
HttpSession session = request.getSession();

Map<String, String[]> params = new HashMap<String, String[]>();

params.put("p_l_id", new String[] {"1806"});

LastPath lastPath = new LastPath(StringPool.BLANK, forwardUrl, params);

session.setAttribute(WebKeys.LAST_PATH, lastPath);

}
}

Both have the same result, page cannot be displayed. Is there a way for me to debug this and step through so i can actually evaluate if once i click submit its actually evaulating the conditions and then see whats happing with the redirect.

after this add the print statement

if (organizations.contains("Consumer")){
forwardUrl = "web/consumer";
}
else if (organizations.contains("Business")){
forwardUrl = "web/business";
}
else if (organizations.contains("Team Leader")){
forwardUrl = "web/teamleader";
}
else if (organizations.contains("Technical")){
forwardUrl = "web/technical";
}
else
{
forwardUrl = "web/consumer";
}

to see what is forward URL

Hi Arvind

I managed to setup netbeans to debug my code, works very well. Basically from what i can see it doesnt seem to find the values inside the organisation list array, it creates the list as an arraylist and adds many values about the organisation into it as there is only one organisation for this user it sets the array at [0]. it then adds the organisation id, name, parent ogranisationid, name etc etc. I thought organisation.contains("Business") would pick up the string value business from the name, but this doesnt seem to be the case.

Any ideas?

Daniel, have a look at another way of setting landing page for each user individually. This one will forward user to private pages of a specific community when user's 'Comments' field has the following line:
default.landing.group=Community Name

You can make something similar, adjust action class to suit your requirements. Source code will be inside the dowloaded jar file. Here is the link.
.

Oh , i missed that part in your earlier code ...

organizations is an array list containing Organization Object . so when you will do organizations.contains("ABC") , this condition will fail.

You can do one thing . Create one more list and add all the names in to that list .



Then check the forward string against new list


}

Hi Victor

Thank you for the suggested solution, it looks very promising and if i cannot get this to work i might look at using this. My only concern with it is with a potential 1000 users it could become very difficult to manage as id have to assign each users default individually, my aim was to use the organisation they belonged to as it meant i could direct them on mass and would be easier when they move organisations etc.

Arvind, i have just updated the code and it works to the point where it should be taking the user to the page, see the attached screen shot of my debug in net beans, and then the screen shot of my page cannot be displayed, it assigns the lath path variable to my website addresss but then it seems not to find the page.

Any ideas?

Does that URL exists . I mean , can the logged in user access http://localhost:8080/web/consumer/home

Hi Victor and Arvind

Got the code working, here it is, im going to post it up for everyone incase someone else ever needs it, the reason it wasnt working is due to the missing params that the original tutorial had in which i left out, including them and it works fine.

I might post this up on a seperate item as ive seen others ask how to do it before and not sure they;ll find it here,

Thank you Victor for your suggested solution and a big thank you Arvind as without you i wouldnt have been able to do this

How would I modify this to send the user to the respective public page of the community rather than the private?

I did using the following way.
