Download Content using CWS from java

Khandelwal_Vipul

Hi

I am able to download a document using CWS from Java, when I pass DataID and Version of the document by calling services of documentManagement and  contentService.

But, I have only Document ID (System Category attribute) for any document which I can pass to the java code.

So, I need to get the DataID and Version against the Document ID, which I can pass.

Here, I cannot query the database directly from Java to get the above values.

Is there any API or service which I can use to get the DataID and version of any document based on attribute (Document ID).

Any help is most welcome. This is really urgent.

 

Thanks

H'mm to me this looks like a young programmer who has not taken any time to know what he is programming against.Livelink a.k.a content server has numbers which you call dataid,objid,nodeid etc.So if I were you I would take one of these ID's that you talk about and put that in the URL of any object's properties,you know you get into livelink and click on any folder link.using the functions button you click that and change that to 'properties'. Now in the URL that is running on the browser replace that with the dataid you have that you say you want to use something in a program.Does it work? did the tabs magically change to a versions as well? If it worked how did that work? the smae thing alos works if you put that number and do a search.

armed with a dataid of a object one if you looks at the WSDL should have a method that gives you stuff about that object one of them is a subtype which we would call as a 144 or a documentsubtype.Only documents in livelink will have that subtype.Now if you were sure it was a documentsubtype you should find another call that says give me the versions.so you have methods in livelink to give you latest version,base version or any version.In fact if you omit the versions number you will get the latest version.So long as the number that you say is the dataid of a document object

Now you introduced another term in your qn (

But, I have only Document ID (System Categoryattribute) for any document which I can pass to the java code .)

H'mm I am not sure what that means Livelink has another object with subtype of 131 called a category object with which you can "tag" metadata . Livelink also has a thing called "additional attribute" that one refers to as "System Categories"

Your assignment gets pretty difficult if all you have is a category id and you want to know how many document objects that are attached with that and perhaps you want to know that as well.Well you have many things in livelink searches,live reports etc.

one final thing the programming against livelink is an extremely simple affair,one has to resist the temptation of thinking livelink programming can be accomplished by only looking at examples or a black box approach.all it takes is to login to the web gui and observe the product , its application logic.The API exposes almost everything you can do with the GUI using a programming language.

hence no examples or code provided .somebody in this forum will give you code.I try to educate... thinking that you may want to do a proper job

I wonder how one could debug livelink  if Fiddler, Wireshark and Softerra LDAP browser was not invented and not free
