Workflow Service Example to get a Attachment ID

****************************************** ***START UPDATE 10/3/2016*****************

LAPI and its client installer has become very hard to find. Moreover clients written in LAPI  in say Java/.NET will only work if your Livelink a.k.a Content Server is of version less than CS16.Readers who are new to LL programming is encouraged to read this to the approach and not to the exact lines of the code.What I mean is when you used to program in LAPI you were basically passing parameters to discrete calls by modelling it based on the webgui of livelink .SOAP based webservices called CWS is also the same,so if you do not try to do the task in the webgui and try to understand the business rules you will almost have no success in CWS too. OT is notorious for not putting fully functioning use cases and a walk through,so whenever possible I write code assuming the user has not worked in Livelink for X number of years and try to educate you all. Livelink,Content Server,Enterprise Server all of this has been Livelink’s marketing brand name changes over the years.CS i sused in many of the integrations like AGA, XECM, RMLINK  and you know you are programming against livelink if you see a link that looks like this  http(s)://somefriendlyURL/livelink.exe|cs.exe|llisapi.dll|cs.dll|livelink.In many places SAP/ SP /Exchange will be configured to talk to Archive Server and then they will use Livelink to read into archive server and turn that into LL objects for better presentment/RM and other aspects. The AGA product is moving away from LAPI(not sure totally or not) to REST API in LL.

A fellow poster in KB is asking for help with Workflow Service examples.

Again my guess is the programmer does not no enough about how livelink handles workflow data structures so hopefully my article does some help. A frustrated developer in this case because there ain’t official samples from OpenText will start to trash the product which I hate to be happening. OT is busy with Core and Appworks(nothing was said about this at conference so is it already dead?) it seems and to this day I cannot understand why OT responses to WebReports is such a high pleasurable experience whereas everything else is basically a lukewarm thing.

I needed to brush my new java skills so I downloaded java samples from KB and started looking at it. It looks to me there is a lot of setup one does with java in C# alsl one does is type a little bit of code….Anyway the poster was using System.out so I am guessing he was a java programmer.There might be several better ways to do it but what I did was convert my old C# code to do that

which was here https://communities.opentext.com/communities/cs.dll?func=ll&objId=10153785&objAction=download&viewType=1.The site is free to the public.

 

1. Workflows are Churned by a map created in livelink See Pic of the new 10.5 Map
2. When you Click Initiate a WF Record is inserted with a pair of dataids called WorkID, SubWorkID in most simple workflows they are the same when you or livelink creates subworkflows they differ.
3. By programming all you are doing is making sure you can get to the running instance and look at its internals
4. It never seldom one changes the logic of map with CWS or LAPI programming.
5. The livelink workflow carries several packages of the workflow,when you say you want Attachments you get a Container much like a folder to put documents,if you say Attributes you get that,if you put a Form template you get that and so on and so forth
6. The above map is reproduced faithfully in a table that is how livelink knows the evaluate conditions etc, if you change the real master map then only instances churned form that will be affected not earlier ones
7. Attributes and Forms are basically going to borrow/rely heavily on categories and attributes code
8. The code for finding the Attachments in a Workflow Instance and downloading it.
9. My code shows how to get one item in the WF Data Structure a.k.a Container ID .You will need to write recursive algorithms if there were folders within that particular id.
