<html:javascript />

The <html:javascript /> tag is used to insert JavaScript validation methods based on the Commons Validator Plugin, which we discussed in Chapter 12, "Working with the Validator." The JavaScript methods used for validation are retrieved from the Validator definition file using the formName as the index. The <html:javascript /> tag has no body and supports eight attributes, described in Table 16.12.
