How to invoke a call to a dll program with java

[admin]

Im a beginner using java in html pages, and this question may seem very easyto answer for a professional java programmer. My doubt is "how can i showa dinamic html page generated by a dll program an its parameters from a databasetable instead of showing a static html page created previously. Is therea way to call this program using java by triggering a click event maybe?and if this is posible, how can i do it ??.thanksZarval
