Installing the LDS-D Component
The sections below describe the steps that you have to carry out in order to set up the LDS-D component on the Lotus Domino server. You have to carry out these steps for every Domino server that is accessed from your portal.
To access the user’s database (.nsf), the LDS-D component must be installed on the same Domino server as that on which the database in question is available. If users are distributed among multiple Domino servers, install the component on each of the servers and create a configuration as described in Creating a Lotus Transport. Alternatively, you can set up one Domino server with replication that hosts all portal Domino users. You can then install the LDS-D component only on this server.

If other JAR or CLASS files are already listed, enter a semi-colon (;) and add the above entry. The path in the Domino server document is based on Lotus Administration client 5.0.12. If you are using a different version of the Lotus Administration client, refer to the Help documentation for the exact location of this property.
Create a temporary
folder (such as c:\temp) for attachments. Attachments are downloaded to the
user’s folder within this folder before read, send, or save operations
are performed. Soon after the operation is performed, the attachment is
deleted from this folder.

To change the folder used to temporarily store attachments, modify the value in the AttachmentFolder attribute in the servlets.properties file in the Lotus Domino data directory.
Update the
servlets.properties file in the Lotus Domino data directory, for
example c:\Lotus\Domino\Data\servlets.properties
with the following
servlet:
servlet.CalendarServlet.code=com.sap.ip.collaboration.gw.impl.transport.lotus.CalendarServlet
servlet.CalendarServlet.initArgs=saveperiod=50,width=7,AttachmentFolder=
C:\\temp
servlet.AttachmentServlet.code=com.sap.ip.collaboration.gw.impl.transport.lotus.AttachmentServlet,useEmail=true
servlet.AttachmentServlet.initArgs=saveperiod=50,width=7,AttachmentFolder=C:\\temp,useEmail=true

If the servlets.properties file does not exist, create a new file in the Lotus Domino data directory.
Update
c:/Lotus/Domino/notes.ini
as below:
JavaUserClasses=c:\Lotus\Domino\Data\domino\servlet;C:\Lotus\Domino\Data\domino\servlet\coll.appl.gw.translotus_api.jar
