can you post your code ?
Please also make sure that jacob.dll is somewhere Windows can find it - as mentioned in one of those links I sent
What happens when you do something like :-
try {
LibraryLoader.loadJacobLibrary();
ActiveXComponent oWord = new ActiveXComponent("Word.Application");
oWord.setProperty("Visible", new Variant(true));
} catch (Throwable th) {
th.printStackTrace(new java.io.PrintWriter(out));
}
