Extend the LENGTH of Attribute using LAPI/Java

I am trying to extend the length of Attribute using LAPI. Following code I am using to Extend/Add the length.

***********

    int status = 0;
    status = attr.AttrSetValues(catVersion, "Publisher", attr.ATTR_DATAVALUES, attrValPath, attrValues);
    if (status != 0)
     {
      System.out.println("AttrSetValues Failed.");

      return;
     }
     else
     {
        attrValues.add( "Length", 150 );
        attrValues.add( "DisplayLen", 150 );
    }

I get below error messge when I do it..

add(name,value) not implemented for this datatype
com.opentext.api.LLIllegalOperationException: add(name,value) not implemented fo
r this datatype
        at com.opentext.api.LLInstance.add(Unknown Source)
        at com.opentext.api.LLValue.add(Unknown Source)
        at ADWC.main(ADWC.java:197)

*************

When I see the ouput of the ASSOC, it shows Length=48. Some of the attributes what we are using are more than 150 charecters in length.

How should I set the length of attribute using LAPI.

Thanks

attrValues is of type List holding the attribute values.To update an attribute definition you would have to use the AttrSet function (see also AttrGetInfo.)

I get the following error when try to use AttrSet function..

Hi Ravindra,

That typically means there was a Content Server error, resulting in an error response.

If you try to dot into the response looking for methods/properties, you’ll get an error like that.

Have a look at your Content Server thread logs (with wantLAPILogs=TRUE in [options] of the opentext.ini).

I think there is a misunderstanding...What you attempt is to modify a category's attribute definitions.For this you have to - first get the current category definition by means of LAPI_DOCUMENTS.FetchCatgeoryVersion, - then retrieve an attribute's definition by LAPI_ATTRIBUTES.GetAttr, - modify this definition (its an Assoc, its properties are documented in the LAPI documentation about "attrInfo"), - set the modified attribute definition by LAPI_ATTRIBUTES.SetAttr, - and finally create a new category version by LAPI_DOCUMENTS.CreateCatgeoryVersion.Attached you find a creepy code example (under the usual "AS IS" disclaimer). It has a rather weird usage, sorry, but something more user friendly was not possible in a hurry.Note: you cannot update an existing category version. This is by design - see the online help about categories. See LAPI_DOCUMENTS.UpgradeObjectCategory how to apply a new category version to an object (i.e. update its metadata to the new attribute schema).
