Procedure
Perform the following steps to add JSPs in BOM Transformer:
1. Copy the created JSP files to the location: Windchill/codebase/netmarkets/jsp/mapsb.
2. Add the following entries to the mpmlink.properties.xconf file to specify the JSP files to be used for the upstream and downstream custom tabs:
<Property name="com.ptc.windchill.mpml.mapsb.DisplayUpstreamCustomJSPs" default="upstreamCustomJsp1"/>
<Property name="com.ptc.windchill.mpml.mapsb.DisplayDownstreamCustomJSPs" default="downstreamCustomJsp1"/>
In the above example, Custom Tab 1 is specified for upstream and downstream structures. To specify multiple tabs in each structure, add comma-separated values without any space as shown:
<Property name="com.ptc.windchill.mpml.mapsb.DisplayUpstreamCustomJSPs" default="upstreamCustomJsp1,upstreamCustomJsp3"/>
<Property name="com.ptc.windchill.mpml.mapsb.DisplayDownstreamCustomJSPs" default="downstreamCustomJsp1,downstreamCustomJsp2,downstreamCustomJsp4"/>
3. Run xconfmanager and restart the method server.
4. Open BOM Transformer. The custom tabs are created and the contents of the JSP files appear on the tabs.

If you copy the contents of one JSP file to another, ensure that the IDs of the tags in the JSP files are different. Otherwise, it can result in issues.
