In this lesson, you will add two .jar files to enable the Lotus® Forms Server API to compute some of the values in the Order form automatically.
To add the two .jar files, complete the following steps. 
- In WebSphere® Integration Developer, select  and expand the list of configurable items by clicking the  . .
- Select .Note: If Java™ does not display as an option, switch to a Java perspective. Select  and switch back to the Business Integration perspective. 
- Add two variables named FORMS_API and FORMS_API2 as shown in the following figure.  These variables point to the location of the .jar files, pe_api.jar and uwi_api.jar.  The location of these files depends on how Lotus Forms Server was installed.  If Lotus Forms Server was installed into WebSphere Integration Developer, these files are typically located at: <WID62_Install>\API\lib\java.  If not, these files are typically located at C:\Windows\PureEdge\76\java\classes.
- Click OK.
