Java - Set attribute value

Does anyone have a java example how to update an attribute value of a document that already has a category attached with some of the attributes already set?

I don't have a Java sample but take a look at the Categories and Attributes (C#) sample I posted here:

https://knowledge.opentext.com/knowledge/cs.dll/Open/17990651

This should get you started with how to work with categories and attributes.

To update an attribute value on an existing node first call GetNode() and then modify the Metadata property of the node containing the existing category information and then call the UpdateNode function.

Hope that helps.

I'm trying to follow the C# example but it's totally different in java.

I don't have an IntegerValue class under docman.

IntegerValue runningTimeValue = categoryTemplate.Values[3] as IntegerValue;
runningTimeValue.Values = new int?[] { 136 };

Here's what have so far:

            // Get nodeID of the document
           objNode = objDocMan.getNodeByName(intNodeID, strFileName);
           intNodeID = objNode.getID();

           // Get the document's metadata
           objMetadata = objNode.getMetadata();

// Get the attribute(s) attached to the document
lstAttrGroups = objMetadata.getAttributeGroups();

// Get the eRexS Documents attribute group
objAttributeGroup = lstAttrGroups.get(0);

Now how do I update the Metadata object? There's no set method at all. I can't do "metadata.AttributeGroups =" like in the C# example.

Perhaps this could help know not...

Thanks for the reply. I read that post but I'm still not understanding how to set the attribute value.

Here's what I have so far:

             // Set the OwnID value
           objDataValue = new DataValue();
           objDataValue.setKey("OwnID");
           How do I set the value now?
           objAttributeGroup.getValues().add(objDataValue);

How do I set the "OwnID" attribute value?

I think I'm close but I still don't know how to set the attribute value:

I'm got it working but I don't think what I'm doing is the best way to do it. Does this look correct?

// Get the effective document's metadata
objNode = objDocMan.getNodeByName(objDocData.getIntEffectiveID(), objDocData.getStrEffectiveDocName());
objMetadata = objNode.getMetadata();
objMetadata2 = new Metadata();
// Get the attribute(s) attached to the effective document
lstAttrGroups = objMetadata.getAttributeGroups();
// Get the eRexS Documents attribute group
objAttributeGroup = lstAttrGroups.get(0);
lstDataValues = objAttributeGroup.getValues();
iterDataValues = lstDataValues.iterator();
for(int i=0;i<lstDataValues.size();i++)
{
   objDataValue = lstDataValues.get(i);
   // Get the DataValue for the OwnID attribute
   if(objDataValue.getKey().endsWith(MigrationUtilProps.getOwnIdAttrID(lstPropList)))
   {
       // Set the OwnID value
       objIntegerValue = new IntegerValue();
       objIntegerValue.getValues().add(objDocData.getIntEffectiveID());
       objIntegerValue.setKey(objDataValue.getKey());
       objAttributeGroup.getValues().remove(i);
       objAttributeGroup.getValues().add(objIntegerValue); do i need to remove then add new?
   }
   else
   {
       objAttributeGroup.getValues().remove(i);
       objAttributeGroup.getValues().add(objDataValue); do i need to remove then add new?
   }
}
objNode.getMetadata().getAttributeGroups().remove(0);
objMetadata2.getAttributeGroups().add(objAttributeGroup);   do i need to remove then add new?
objNode.setMetadata(objMetadata2);
// Update the effective document Node
objDocMan.updateNode(objNode);

Does this get answered by anyone yet ?

I don't see docman webservice has all those Objects available in C# , so C# samples are useful to some extent , but using Java Docman api methods seems lacking few object defintions .

If anybody has any example of how to read/modify an Attribute Values using Java Docman web service , please share.

This replay is late, but we set attributes all the time in Java. Here is some code that might help.
