Can I use Swing in Servlets?

Can I use JOptionPane.showConfirmDialog in my servlet? When I test on the live web server, a classnotfound error is found.

If not, how can I call the windows message box from my servlet?

What type of windows dialog box?? you just want a box to pop up to tell them that their stuff was submitted or accepted? If thats the case, you would inbed some javascript to call the box.

this is a long javascript that pops up a little window if someone didnt enter at least 3 characters in a box or forgot to enter something in a text box... i am just too lazy to edit it for you right now... you can take out all the if statements and make it say what you want... I am not sure if you have any exp with JavaScript (it is new to me) but you have to call the script from an event like link click or button click... i will give example of it after this script


out.println("<SCRIPT LANGUAGE = \"JavaScript\">");
out.println("function oops(form1) {");
out.println(" if (form1.actDesc.value == '') {");
out.println(" alert('Please insert a description.');");
out.println(" return false;");
out.println(" } else if (form1.actType.selectedIndex == 0");
out.println(" && form1.actName.value == '') {");
out.println(" alert('Please insert an activity.');");
out.println(" return false;");
out.println(" } else if (form1.actType.selectedIndex == 0");
out.println(" && form1.actName.value.length < 3) {");
out.println(" alert('Activity must be at least 3 characters.');");
out.println(" return false;");
out.println(" }");
out.println(" form1.submit();");
out.println("}");
out.println("</SCRIPT>");

Then wherever you may call the script kinda like

out.println("<TD colspan=2 align=center><INPUT align=middle name=actSubmit type=button value=\"Submit This Activity\" onClick='oops(document.agentAct);'></P>");


hope this is kinda what you were looking for.

eh?... swing in servlet?....
first time hearing this.

Swing is for GUI.. Servlet is a server-side tech...
i know you can use a Servlet to create HTML tag
or javascript and send it back to the client side..
then the client side will do interpretation for
the these 2 tags and send more requests to the server
by looking at what items are requested inside the tags.
e.g. an Applet

you can use Swing in the Applet, but duno if all
browsers are supporting it. The Applet can call
a Servlet and communication with it...

that's all i know, hope it helps.
