Getting List of Documents with LAPI 2

Hi there,

i am stuck... i am trying to get the Itemnames of Documents in my Contentserver via LAPI. My Code:

LLValue numberOfObjects = new LLValue();
doc.GetNumberOfObjects(0, 14869, numberOfObjects);
Console.WriteLine("Number of Objects " + numberOfObjects.toInteger());

LLValue node = new LLValue();
// LLValue node = (new LLValue()).setList();

doc.ListObjects(0, 14869, "DTree", "subtype=144", LAPI_DOCUMENTS.PERM_FULL, node);
LLValueEnumeration enumVal = node.enumerateValues();
while (enumVal.hasMoreElements())
{
LLValue element = (LLValue)enumVal.nextElement();


String name = element.toString("Name");
int id = element.toInteger("ID");
int pid = element.toInteger("ParentID");
int subType = element.toInteger("SubType");
Console.WriteLine("Node " + name);

}

getting the correct Count of items works fine... so basically i have a connection. so when i try to get the list, i got serveral errors. I i choose 0 as VolumeID i get an
toInteger() is not implemented for this datataype Exception
if i coose 2 or 4 as Volume Type (i got these number from my archive server) the listObjects routine works fine, but when i come to node.enumerateValues(); i got:
enumerateValues() is not implemented for this datatype

i dont know what i amm doing wrong, or if there is an other possibility to get the objects.

What i plan to do is, write a small .net programm in which i will show a Tree of some existing documents. Therefore i need the names.

thanks
mcnanuk
 
if i try:
doc.ListObjects(0, 2000, "DTree", "subtype=144", LAPI_DOCUMENTS.PERM_FULL, node);
and no document is located in my workspace i recieve a valid empty enumeration.
if i put one .txt file there... i recieve the error toInteger() not implemented ....

maybe this helps
 
Your enumeration is wrong for e.g what we are trying to do is basically try to represent header info like

dataid,parentid,subtype,ownerid
1234,1234,144,0
1567,0,0,0

when you say enumerateValue you are sitting at a value record.What you want to do is enumeratenames.The volume number really has no meaning unless you were enumerating a container object like project or discussion.archive server volumes are different and they are not known to the livelink schema.Livelink talks to archive server using http api's

See a working example concentrate on the printtypetree I have a hardcodedm objid in the example that is a container in my livelink ,and sufficient comments in the code

Thanks....

lets say: doc.ListObjects(0, 33346, "DTree", "subtype=0", LAPI_DOCUMENTS.PERM_FULL,node);

33346 represents a folder. Within this folder are 2 files located.
What do i have to do, to get these two filenames, or mime.types


i got your code running, and it works. it gives me a list like:
|: - Type is TABLE
|VOLUMEID - Type is LIST
|PARENTID - Type is LIST
|ID - Type is LIST
|NAME - Type is LIST
|ORIGINOWNERID - Type is LIS
|ORIGINDATAID - Type is LIST
|USERID - Type is LIST
|GROUPID - Type is LIST
|USERPERM - Type is LIST
|GROUPPERM - Type is LIST
|WORLDPERM - Type is LIST
|SYSTEMPERM - Type is LIST
|ACLCOUNT - Type is LIST
|PERMID - Type is LIST
|TYPE - Type is LIST
|CREATEDBY - Type is LIST
|CREATEDATE - Type is LIST
|MODIFIEDBY - Type is LIST
|MODIFYDATE - Type is LIST .......

I dont see, how this could help me. Thanks again for your help
 
*bonk against my head* okay ListObjects doesnt list all children... it lists all fields from one specific item.

so i have to find out, how i get all DATAIDs which have the same PARENTID.

Is there a way like: select * from DTREE where subtype =144, just using this sql in LAPI ? Something like a Statement using jdbc drivers in Java.
 
Mimetypes are not in the dtree/webnodes record as you want.also lapi is very old type of datastructure programming,OT has discontinued dev and use of it but people like me who did not have the liberty of websvcs still make use of it.

Code:
select dt.name,dv.mimetype from dtree dt,dversdata dv where dv.docid=dt.dataid and dt.dataid=944708

In fact if you search greggriffiths.org I wrote a lapi downloader which uses a jdbc connection may not work now because java has progressed tremendously but I used the relation above to burn a folder full of livelink objects.the file is called Bulk Fetch
you should be able to use purely lapi to get everything you want by recursively going to each container you encounter some clues in this for you

BTW see if you can download EasyLapi from the kb all these crazy data structures have been encapsulated into useful calls so it looks more or less like one java call.For e.g there may be a call to give you a recursive listing in one shot

Sorry I should have mentioned that before sending you on raw lapi stuff it might be a whole lot easier and un frustrating

thanks again....

but this also leads me nowhere :D
I AM IMPATIENT SHOW ME JUST NAME***************
|: - Type is LIST
I AM IMPATIENT SHOW ME JUST SUBTYPE***************
|: - Type is LIST
I AM IMPATIENT ALL I CARE IS THE NAME RECORD***************

the children Object contains no Values. I choose a folder which contains two *.msg Files: Parentdir is 2000.

I found a way of getting the information i want:
doc.GetObjectInfo(0, id, dirInfo);

but to use this, i need the DATAID. Is there a way of getting ALL Dataids contaning in the contenServer? I dont see it. ListObjects might no work for that. Or is there a mistake ?
 
RUN your listobjects call without a subtype filter and try to understand what the call is doing
what is your output when you run select * from dtree where parentid=2000 do you see your two msg files in that.If so list objects also is doing that

Is the lapi user connecting a user who cannot see the files permission wise? can you for testing use the livelink user 'Admin'

Here's how livelink uses the ListObjects to show you the hierarchy

2000(Enterprise)
1234(subtype 0 My Folder)
1568 (subtype=144 My Document inside it)
1345(subtype=144 My document)

If you do
ListObjects without a subtype=filter
on 2000 and assuming you have permissions to see all the children it will display
2000
1234
1345

It will not show 1568 because the call will not recurse into 1234.You have to code to do the traversing.

If you do ListObjects on 2000 with subtype=0

1234

If you do ListObjects on 2000 with subtype=144
1345

That is how the oscript code(the lapi converts into oscript) is written,if it is not happening for you you might want to ask OT suppport why it is not working the way it should be.

String ViewName, String QueryStr, Int32 Permissions, LLValue children)
bei OpenTextTest.Program.Main(String[] args) in C:\Users\Outlook\Documents\Vi.....

i dont know what is wrong here. If i select 33346 as Objectid, and paste subtype =144 i got the same error, if i put subtype=0 it is working, but only gives empty results like i postet above.
The user i connected with has all viewing rights... he is the owner of the docs.

same tointeger Error occurs, when i use: String queryStr = "";
 
okay .... i solved it !

String viewName = "DTREE"; was the problem

Code:
 parentVol = 0;
                    parentID = 2000;
                    LLValue children = (new LLValue()).setTable();
                    String viewName = null;
                    String queryStr = "subtype=144";
                    status = doc.ListObjects(parentVol, parentID, null, queryStr, 0, children);


i had to set viewName to null.... now i am gettig all the Information i want.... maybe you can explain it to me, why "DTree" is not working, like in all examples i found. Also in the documentation it is mentioned to use Dtree if you want all columns .... i would be happy to get an explanation
 
if viewname is null then webnodes is used listnodes is a call that can be maliciously used.You have to sometimes enable calling tables in livelink.if you search in KB you can get the real scoop on that.You have to do something like whitelisting and blacklisting I cannot determine for sure until I can see debug logs

Well, if I called the wrong number, why did you answer the phone?
