Using LAP to modify Admin page preferences

Nishan_Vijayaratnam

Hi,I am wondering if its possible to USE LAPI, to update flags or preferences on the Admin page and if there are examples out there.Specs: LL 9.5 SP1, coding in JavaSpecifically, under Custom Module Administration, I have a flag that I want to toggle on and then toggle off after execution. Is there anyway to get into the Admin page or the database table where this is stored and manipulate from the backend.Thanks.

Perhaps if u could post a little more detailed info the members could help.Livelink stores preferences in many ways sometimes it is the table kini,sometimes it is kuafprefs and sometimes we read off preferences from an ini file.None of these can be manipulated by lapi other than the fact that if you know how to access tables/files this could be made into a 'kludged' solution.Oscript would be more ideal.Frankly I cannot understand how an action in lapi code has to effect a module setting to put an example we have notifications enabled as a flag.Would you be saying that you would have to have a way thru lapi to update the flag so notifications is not enabled anymore would that be a parallel to a flag in your custom module.If you know where your custom module stores its info then perhaps lapi could just do a table update .

I think we are on the same page, but to re-state. Lets look at the Configure Notifications section on the Admin page. There is an Enable and a Disable option. If I were to toggle this, that is disable or enable it, you are saying it would be best to use OScript or to go to the DB directly and do a table update for that field?I looked in kini table and could not find any references to the field I am looking for.Thanks.

NO NO NO NO NOWhy if it was oscript I could find the corresponding oscript command that does the same GUI action.This would mean that I don't need to know all the associated schema for this eg how would I know whether to update agentschedule,notifyinterest2s etc and what key and by what filter unless one was the original designer for the app.So a better design would be either when you design your custoemmodule you would either choose to use kuafprefs,kini or ini and use ocript methods.Oscript allows you access of these tables by oscript methods that are very self explanatory.If you directly update tables of core livelink you do not ever know if OT intended lots of extra code (callbacks) to run so you will put the whole schema in a compromising state.

A lot of things in Livelink are cached at start up (like the enable/disable option mentioned above). Changing these types of things after startup requires a stop/start of the Livelink service...which you will not be able to accomplish via LAPI.You would just have to figure out (trial and error) if the setting you want to change is cached or not...

Nishan_Vijayaratnam

Thanks for the response, seems like I should look at oscript but then I would need to call it as a Windows Scheduled task to toggle the preference on/off.However, I was looking at the following functions in the Java API documentation and was wondering if I cannot utilize these. As you said though< i would need to know the property name to retrieve?com.opentext.elf.plugin.core.prefs.ServerPrefs.getSystemPref(String section, String key)Returns the value of a system preference specified by sectoin|key.com.opentext.elf.plugin.core.prefs.ServerPrefs.getSystemPrefs()Returns a map contains system preferences from both INI file and INI table.

Nishan_Vijayaratnam

Thanks John. I will use trial and error to if that is the case, I am thinking that since this is a scheduled task, I can schedule the LL Services to restart after this or do a script to restart as part of the process.

Appu_Nair

you can call those only if your livelink is running on a appserver infrastructure or whether a java servlet deployemnt of livelink is running IMHO:)Anyways the java port of livelink has entered maintenance so probably would run into problems anyway.But there ought to be a one to one match of oscript and java calls.I never did take on to that ll dev.

I am going to try and print the below out and see if what I get back. Have you used this before? There is no constructor for the ServerPrefs class but there is a getInstance() method. However, it does not specify how this is tied into the LLSession or what the fileSpec is that must have already been called???ServerPrefs llfetch = ServerPrefs.getInstance(); // #getInstance(fileSpec) method must have already been calledMap LogFile = llfetch.getSystemPrefs();Map IniFilePrefs = llfetch.getINISystemPrefs();Map UserPrefs = llfetch.getUserPrefs();

Nishan_Vijayaratnam

I got the code working, upto connecting to the enterprise workspace and retrieving some IDs, however I am unable to get the .getSystemPrefs() function in ServerPrefs class to work because of initialization. It doesn't seem to like me doing just ServerPrefs.getInstance(). Any help on what is meant by // #getInstance(fileSpec) method must have already been called, is much appreciated. It seems to throw a initialization error due to this, no lloml in java.library.path.Thanks.

Message from Carsten Kulms via eLinkIf I understand correctly what you are trying is to utilize code fromthe Java Modules SDK in a LAPI client.This cannot work. LAPI and Java Modules are very different things.

Nishan_Vijayaratnam

Hi Carsten,Thanks for the reply. I am actually just using Java API, but the documentation is a limited in the initialization of the classes. That is, you can look-up the class, but it does really say how to initialize the class or tie it into the session object. I do not believe I am mixing the LAPI and the Java code here, cause I can successfully connect to the Enterprise workspace, retrieve the ID and disconnect. However, I am unable to go further and retrieve the opentext.ini file preferences or the kini table preferences.So, the question was given that I have a LLSession and a LAPI_DOCUMENT, how do I use the java classes or initialize or connect to LLSession:1. SystemPrefsFile llfile = SystemPrefsFile();or2. ServerPrefs llprefs = ServerPrefs.getInstance();For example, I cannot do: SystemPrefsFile llfile = new SystemPrefsFile(LLSession);Thanks.

Nishan,

You should know that Java Modules just providesread-only functionality and to the best of my knowledge is now in maintenancemode.

You should also know that while LAPIprovides for read/write functionality it too is now in maintenance mode. So ifyou are writing code that you hope to use for years to come then I suggest youseriously consider writing your code in either Builder or Web Services.

Howard

Hi Carsten,

Thanks for the reply. I am actually just using Java API, but the documentation is a limited in the initialization of the classes. That is, you can look-up the class, but it does really say how to initialize the class or tie it into the session object. I do not believe I am mixing the LAPI and the Java code here, cause I can successfully connect to the Enterprise workspace, retrieve the ID and disconnect. However, I am unable to go further and retrieve the opentext.ini file preferences or the kini table preferences.

So, the question was given that I have a LLSession and a LAPI_DOCUMENT, how do I use the java classes or initialize or connect to LLSession:

1. SystemPrefsFile llfile = SystemPrefsFile();
or
2. ServerPrefs llprefs = ServerPrefs.getInstance();

For example, I cannot do: SystemPrefsFile llfile = new SystemPrefsFile(LLSession);

Thanks.

Carsten_Kulms

Message from Carsten Kulms via eLinkLLSession and LAPI_DOCUMENTS are classes of the (good old

) LAPIwhereas SystemPrefsFile is a class of the Java Modules stuff. Thereforeyou cannot bind it to a LLSession--LAPI and Java Modules are differentconcepts with different and separate purposes.Remove everything from your classpath except the lapi.jar and you willsee what I mean.Sorry, I'm quite sure there is no way to achieve what you want by meansof LAPI. (And even if you would develop a Java Module you will notsucceed, I think.)

Nishan_Vijayaratnam

Folks,Thanks for the responses here, this turned out to be simpler than expected as the custom module had the params in the opentext.ini file. The utility was written in Perl and did what was required.
