How I can retrieve the category-object from a document with the API for 9.0.0.1 ?

Hi Robert, here are the calls I use to get and set attributes: LAPI_DOCUMENTS documents = new LAPI_DOCUMENTS( session );LAPI_ATTRIBUTES attributes = new LAPI_ATTRIBUTES( session );LLValue objID = ( new LLValue() ).setAssocNotSet();LLValue cats = new LLValue();objID.add("ID",33333);// list all cats associated with the object 33333:documents.ListObjectCategoryIDs(objID,cats);// get the first one:LLValue catID = cats.toValue(1);String catname = catID.toString("DisplayName");LLValue catVersion = ( new LLValue() ).setAssocNotSet();documents.GetObjectAttributesEx( objID, catID, catVersion );// list attribute names for this category:LLValue attrnames = ( new LLValue() ).setAssocNotSet();attributes.AttrListNames( catVersion, null, attrnames );Hope it helps.Sergey

Hi Sergey,Could you tell me what are the next instructions to get and set attributes. I dont know how to extract the information from "attrnames".ThanksRachel

Hi I am using GetObjectAttributesEx( objID, catID, catVersion );for getting the catVersion which is working finewhile i query for catVersion.size() it gives me 3My problem is setting of values to an attributeby using AttrSetValues.I do it in the following way:-LLValue attrValues= new LLValue().setList();//attrValues.setString("700");//here Amount is the attribute nameString amount="Amount";attrValues.add("500");attributes.AttrSetValues( catVersion, amount, LAPI_ATTRIBUTES.ATTR_DATAVALUES,new LLValue(), attrValues);I then use documents.SetObjectAttributesEx(catID, catVersion );when I do this and add the documents the document getsadded but the value for the attribute Amount does not changeand it is the same value as the folder in which i put the documentPlease help me out .Qhat error am I making. This is quite urgent.thanx

Here is a code fragment of how I get NATIVE JAVA TYPES out of the JAVA LAPI.I have yet to do a set of attributes, but I only imagine it is also as straightforward ;-). public Hashtable getCategories(int volId, int id, int verNum) throws LLException { //our return value Hashtable retVal = new Hashtable(); try { LLValue sourceObjectId = new LLValue().setAssocNotSet(); sourceObjectId.add("ID",id); LLValue categoryIds = new LLValue(); int i = this.getLapiDocuments().ListObjectCategoryIDs(sourceObjectId,categoryIds); if (i != 0) { throw new LLException(i,this.getSession()); } else { Hashtable category = new Hashtable(); LLValueEnumeration categoryEnumeration = categoryIds.enumerateValues(); while (categoryEnumeration.hasMoreElements()) { LLValue categoryId = categoryEnumeration.nextValue(); String categoryName = categoryId.toString("DisplayName");//System.out.println("categoryName="+categoryName); LLValue categoryVersion = new LLValue().setAssocNotSet(); i = this.getLapiDocuments().GetObjectAttributesEx(sourceObjectId,categoryId,categoryVersion); if (i != 0) { throw new LLException(i,this.getSession()); } else { LLValue attributeNames = new LLValue().setAssocNotSet(); LLValue attributeValues = new LLValue().setAssocNotSet(); i = this.getLapiAttributes().AttrListNames(categoryVersion,null,attributeNames); if (i != 0) { throw new LLException(i,this.getSession()); } else { LLValueEnumeration names = attributeNames.enumerateValues(); while (names.hasMoreElements()) { LLValue name = (LLValue)names.nextElement();//System.out.print(name.toString()+"="); i = this.getLapiAttributes().AttrGetValues(categoryVersion,name.toString(),LAPI_ATTRIBUTES.ATTR_DATAVALUES,null,attributeValues); if (i != 0) { throw new LLException(i,this.getSession()); } else { LLValueEnumeration values = attributeValues.enumerateValues(); while (values.hasMoreElements()) { LLValue value = (LLValue)values.nextElement(); String s = ""; //you have to parse here for the LLValue type and convert it to a Java Type if (value.isString()) { s = value.toString(); } else if (value.isDate()) { s = value.toDate().toString(); }//System.out.println(s); category.put(name.toString(),s); } retVal.put(categoryName,category); } } } } } } } catch (Exception e) { e.printStackTrace(); throw new LLException(e.getMessage()); } return retVal; }

Hoi Sergey,Is it meant to do a cats.toValue(1) for the first LLValue in the LLValue of cats? Does this mean that the folks at Livelink have implemented their LLValue objects with a starting id of 1 (That would make as much sense as the rest of the LAPI)?Look at my later post that uses an LLValueEnumeration to iterate through the Categories rather than using a numerical reference.Ciao,Jon K
