Maurizio Cucchiara's answer seems like a good idea excepting I have add the personbean.name=xxx. (The personBean is required) I do not want to use the ParameterAware,I want to use a object save some default value of some parameters rather than the map. Also,if using the parameterAware,why not using the ActionContext.getcontext().getParameters() instead? > > Jason > > On Mon, Nov 29, 2010 at 5:25 AM, maven apache <apachemav...@gmail.com > >wrote: > > > 2010/11/29 Maurizio Cucchiara <maurizio.cucchi...@gmail.com> > > > > > Frankly, even after I watched your question on stackoverflow, I can't > > > figure out what you meant. > > > > > :( > > > > > You don't necessary need struts tag, you can pass parameter via http > > > request, so, for example, if you enter > > > http://your_url:your_port > > > /your_struts.action?personBean.firstName=your_name > > > in the address bar > > > > > Thanks. > > > > I use the http://xxx.action?firstName=name.
