Hi Jose,
thanks for your response. Actually you can split my post in 2. - In the first part, I ask how to use Struts 1.0.X in order to implement ActionForms that could match HTML forms with a number of parameters known at runtime. I have solved the problem for checkboxes, by defining a parameter of type String[] in ActionForm with its get/set methods. The JSP checkboxes could be something like: <html:checkbox property="mycheckbox" value="on1"/> <html:checkbox property="mycheckbox" value="on2"/> <html:checkbox property="mycheckbox" value="on3"/> ....` In that way I am able, in validate() method of ActionForm, to get [on1, on2, on3...] (supposing all of them are checked by user). I mean, I am able to distinguish in the String[] which on* belong to which JSP <html:checkbox>. To write on1, on2 and on3 in HTML page source I fall again in the problem of not been able to embed custom tags but that is a minor problem. (I want to avoid scriplets in JSPs). My intend is to extend previous for <html:text> and other struts tags, but, I can not figure it out, specially <html:text>. I intend to do it without upgrading to Struts 1.1. Anyone with ideas about how to get inputs from several <html:inputs>, radiobuttons, etc is very welcome. - Second point is more an suggestion, or at least, to get info why it has not been posted before. The idea is to enable Struts to work out ActionForms itself, specially suitable for that I meant before, JSP forms obtained at runtime, as a consequence of results of a database query, by instance. I would like to know why DynaBeans, could not be applied for it. Another idea, as someone posted before is using BCEL from Jakarta, but I agree that it is really really cool. However, if I missuderstood something or I am in some mistake, any correction would be really really appreciated.
