if you create the Script from QC it will always have the Web Addin as Default. U need to First launch QTP, load the addins, then Save into Qc to insure that the Addin are stored with the test. you can also Load QTP with Java, open a QC Script with Web and add in the Jasva and resave for all the existing scripts.
1.) start QTP with the AddIns you need (select it from the first screen, the AddIn screen is shown by default
2.) open the test (from QC or from anywhere else)
3.)go to the test settings (File -> Setting)
4.)press the button "Modify"
5.)elect/deselect the addins like you want (you can only see loaded AddIns)
6.) save your test (in QC)
7.)on the next test start via QC (Test Lab) the test will be loaded with all the associated AddIns
