Demise of communities.opentext.com

RIP communities.opentext.com

Years of developer activity retired…. Just like that

How would a developer who does not have access to KB find anything informative?

Is that intentional?

Why wouldn’t  OT give out a fair warning to migrate content for content owners?

Much of code I kept for public consumption was here

So if anybody is looking for that write me I will try to find from local copies

General Help Series 3-Privileges (Am I allowed something)

Privileges

Privileges apply to you as the “user” versus permissions are what the Object allows a “user” to do.There are differences.For e.g for installing something in windows you need to be part of the “administrators” group similarly to install something you need to be in the “system administrators” group. A “administrator group user” has almost very high privileges to do things in a OS similarly they have a high degree of authority in livelink as well.So when a user is created we set at the minimum these privileges Login Enabled and Public Access So when a objects is accessed at run time livelink’s algorithm is does user have login,does user have PA and does Object have PA and what like S,or SC so it is a given that the user will be able to click the link. In very simple terms use PA effectively to address contents that is useful for the whole environment almost like using livelink as a glorified web server.

Now other things are self explanatory has User Creation,System administration and others leading to making Group Leaders etc.In short if you spend some time understanding the architecture you will be amazed and the simple but very effective thought being given into its devlopment.

The Add New Item Truth Table

The livelink system is replete with several subtypes some  of the are very useful and harmless like folders,documents etc so nobody changes anything from default. However you would be very concerned if somebody go unauthorized access to Live Reports,workflows,form templates etc,so what I do is I will look at the personal workspace of a default user and see all the “New Items” being shown there.Then I evaluate what should a untrained user be allowed to create in my system.For all the complicated ones I will create a manual group called “r-Form Template Creators” and add ‘Admin’ to that.Now if I have trust to give a group or a user I would expand my group.So when these new person goes and he has permissions to “Add Items,Reserve , Delete” this user will see “Form Template” there. However h(s)e moves to another folder where he has only “S,SC” he does not see it there.Note different object subtypes do different things.I am not keen to explain everything like Tasks,Discussions,Projects ec they are for you to explore and set right.Before releasing a system to production give a simple user access and do some Gorilla Testing  that will help you more than the amount of money spent on stress testing.Obviously you should have at laest oe or two good front ends and a good beefy admin server to do your search stuff.

General Help Series 2-Permissions (Would the Object allow me to do this)

Permissions 

At the outset a Livelink system represents some vestiges of a File System like Unix or Dos.People having worked in that is probably familiar with the term U G O which stood for User,Group,Others.This is what you see in the std permission bit of an object on its ACL. Every object has one ,many times you set the container object right and let the inheritance trickle in.In many places if you set it right you can forget it.But if you install livelink Out of the Box and has no training or nobody to watch it over you are probably going to end up in rogue territory.This is because the user ‘Admin’ and ‘Default Group’ has very high permission bits set.Out of which the owner is a role,so if you start a folder where Admin did not willfully do the permissions set normalization and if you gave ‘Appu’ creation privileges  for folder when ‘Appu’ creates objects he becomes owner who is very powerful and so on.Now this could be argued as not a big problem until it runs amok.So what a good permission model is Owner See,See Contents or Nothing,Group See,SC or Nothing and PA,S,SC or nothing.Now you will create administrative groups something simlilar to these discussions and you will be fine.

Always rely on proper groups that you can create and maintain in a directory service (AD is very common) and have those groups synchronized in.It is quite possible that HR systems release feeds into Directory services hence when users leave your organization they will go as well.There will be no permission problems because the real administrative group has overriding permissions that the owner based approach.Simple try it and  you will be happy and 50 % of your help desk tickets will come down.

This is what one hears in OpenText engagements as “Community Modelling” well my next part will cover object truth tables as well.

Permissions bit use BitWise logic in FileSystems as well as livelink does recently a programmer told me he finds the awesome bitwise logic un understandable.I just thought wow where is the programming world heading into 🙂

There is nothing wrong in owner having high permissions so long as the administration is willing to support it and understand it.

Security Clearance and Supplemental Markings are OT’s way of securing against inheritance rules in big hush hush organizations.

HTTPS with Webservices in Livelink

Contrary to stuff that I do this post is basically something I hacked together to make it work.I must have received at least 50 emails for several web services questions.In the absence of OT providing good easy to understand hand holding examples I offer these.If OT ‘s thinking is basically to code a web service a developer needs to take paid training all those things have come to pass.Almost every programming language snippets are available and so there is an expectation that the Vendor provides proper code samples.What I think they should start putting quality samples like what Jason is attempting &  conducting webinars .They could do several official things such as how to code when RCS is present, what is the difference between Enterprise Library Services & Livelink web services,How does the new OTDS come into authenticationg into livelink,What one should do and not do,many things the livelink programming community needs help on.This in my mind will ensure a good talent pool of programmers out there who would do things as OT intends to.

I naturally like to understand what I am doing unfortunately in this installment I have resorted to mostly ‘trial & error’

HTTPS and Livelink Web Services code

As we learned on our SSO attempt and livelink web services this time we start with this

Part 1

  1. Make VM IPv4 and disable IPv6 it should work for IPv6 provided you do the stuff in my previous blog.
  2. Make sure the IIS7 livelink webserver is functioning fine
  3. Make sure anonymous(livelink) authentication is fine  i.e.’ we can login as the powerful ‘Admin’ and the right password.
  4. Now with our baseline favorite Kyle Swidrowich’s piece of code start making it work without https
  5. We then make IIS HTTPS. Note you cannot make a webserver https commercially without shelling some money.HTTPS needs a certifying authority. For purposes of demonstration I will be using Microsoft’s self-signing certificate. Self-signing certificates are the same secure protocol other than the fact that a commercial company will not stand by it. Products such as archive server uses self-signing certs and OT bundles a signer program so I have used it many times to create closed loops between SAP ,livelink and archive server. For the completely uninitiated a secure transmission means only with the private key can you decipher the communication between the browser and the application so snooping with fiddler/wire shark etc. will give you a lot of garbled messages.
  6. So we manage to login as HTTP on that livelink

Again VC#, At this point this looks promising, Now add quickly DocumentManagemnt.svc and ContentService.svc as well Try Kyle’s code and make it work for HTTPS .Perfect everything works we added the document

Part 2

Making IIS HTTPS

I used this site and followed that

see how simple it was for me a non MS/IIS person to figure this out that is what we sadly lack with OT.

BTW word press cannot do embedded images from my word document.I have the word document replete with screen caps in communities.

And this Now for good measure we need to remove http

If you remember a posting I made and Guy Pomerleaux commented if you have http and https running and OT web services code  is accessed you don’t really know you are talking https unless you do this. To keep it simple my livelink is now HTTPs Web GUI or web services. Perhaps if you leave a http listening port this would make your coding easier, but since I am doubtful which protocol will be used I resort to this.My builder program reports HTTPS=on that tells me everything is SSL.

We say yes to the IE warning and proceed to our newly created Livelink website which is now on HTTPS

We have cert errors even after we import the cert to keep IE happy

But I guess it will complain until I paid VeriSign or Thawte some money Perhaps readers can pool some money and buy me a certificate J for all practical purposes I am https

When I try to change my web service references we get this

I say yes

I got this and plenty of yellow looking errors at the livelink web services server when I tried to call the web service. Too many to list and too unknowing to comment on the mumbo jumbo.Essentially at this point I am trying on the server to get this service created.

https://appuw2k8vm/les-services/Authentication.svc

Several errors ensued which I basically got around by removing all traces of places I thought was written for HTTP stuff.

So I remembered form my 9.7.1 that there is some SSL binding stuff we have to do on the web services on the server. So we make a copy of the Web.Config and try it.

Mostly if you remove everything that did not contain SSL and enable the SSL stuff it should work.

Also could not establish trust relationship means you have to install the certificate into the trusted certificate store

A working Web.Config you can find a working app.config you can also find. I am not able to explain the mumbo jumbo as it is mostly trial and error. I hope if any OT knowledgeable people read this they would conduct a webinar on how to do this.

Link 1 The above article replete with screen caps as a word doc

Link 2 The Web.Config that goes on the web services install that works for me 

Link 3 The App.Config from my C# application

To jQuery or Not to Jquery

(ODD results is SAP ,EVEN is CS)

Recently a poster facing problems with how xECM and Livelink manages content posed this question.He basically wants some results excluded when a search is performed.The correct implementation of this is by permissions.The poster wants to use appearances and cheap gimmicks like that .I also do not really know a lot of advanced html so when I hear people rave about jQuery and its infinite possibilities I am  usually thinking wow I could never understand those.Note any self respecting programmer will be able to trace the weblingo of my implementation to a file in the livelink directory  Here’s the question posed by the poster in KB RE How to restrict Function Menu in search result?

Now a fair amount of warning as advertisers put in Advertisements .Professional do not attempt this at a live livelink installation. You need to really use htmlmap, overrideutils or customizations_RT before attempting this.But here’s the  jist of what I am doing

For some context I am considering every odd row of my results to be coming from SAP and evens to be “showable with the function menu”. So if we look at the source of the document of the  searchresults in a 9.7.1 livelink I see this the ‘x5’ is the dead giveaway in this case.Since I mess with oScript all the time I can see that count going x1,x3,x5,x7 etc…..

<A HREF=”javascript:(0)” ONCLICK=”javascript:setSectionName(”);showFunctionMenu2(‘nextURL=%2Flivelink%2Fllisapi%2Edll%3Ffunc%3Dsrch%2ESearchCache%26cacheId%3D1125829432’, 5, event, ”, ‘?func=SearchResultsFunctionMenu&amp;hitID=5&amp;searchCacheID=1125829432&amp;version=0&amp;dataID=62740&amp;HH=false&amp;subtype=264’ );setSectionName(”);return false”><IMG SRC=”/img/actions.gif” ID=”x5″ BORDER=”0″ ALT=”Functions” ></A>

Now that we have done our research we need to see if we have JQuery in livelink. In short of time and doing this not for money and interest only in this I googled and downloaded

jquery-1.8.2.min.js and then I found this file called resultlist2.html. It is my livelink on a VM and I have a snapshot thing so I am doing in place editing(Tsk Tsk Do Not Ever Do It)

Now I put where OT has a js file .My oscript tells me that that is the webnode support directory

<SCRIPT TYPE=”text/javascript” SRC=”`webNodeImgPrefix`browsecorermenu.js” LANGUAGE=”javascript”></SCRIPT>
<SCRIPT TYPE=”text/javascript” SRC=”`webNodeImgPrefix`jquery-1.8.2.min.js” LANGUAGE=”javascript”></SCRIPT>

Now to see if everything works we need some tests

so from the web lots of excellent samples I put these together

<script>
$(document).ready(function(){
$(“p”).click(function(){
$(this).hide();
});
});
</script>

<script>
$(document).ready(function(){
$(“TR”).click(function()
{
$(“#x1”).hide();
$(“#x3”).hide();
$(“#x5”).hide();
$(“#x7”).hide();
}

);
});
</script>

<script>
$(document).ready(function(){
$(“a”).click(function(){
$(this).hide();
});
});
</script>

This is like a recipe in a cookery show.I must have spent close to 3 hrs twiddling with what I am doing.Note I would have been able to do this in oscript much faster but that was not my intention.I wanted to learn Jquery so that is why this looks weird if there are a some oscripters going  “that appu he is really going down the edge….”

Now when I restart my livelink and conduct a search all my ODD results don’t have any function menu.Here’s when the page loads first

Full Results

Now when I click that is I have a event that says when the <TR> area is clicked that is when my event fires

What remains maybe do it for real when it is called for remove the hard code and put a real counter,maybe make it work without the <TR> click event….

I am sure the poster gets some kind of header variable like MYSAPSSO2 in livelink so some keying off that and implementing the business rules could be thought off

This is great Long Live JQuery….
