How to print report from JSP Page

Hi Everybody,
I am developing a simple project in JSP with MS Access. I hav some tables and reports for them. I hav a JSP page which gets inputs from user and save it in the table. Its working fine. But my problems are,
1) I hav a button called "SAVE & PRINT" in that bottom of the page, if i click that button, the currently entered data has to save in the table and the same data has to print from the MS Access report. I dont know how to print this report from JSP page.
2) Another button called "REPRINT". If i click that button, it has to ask a number to print the report page, that number is nothing but a field in that report.
Could anyone help me to solve this problem.

Urgent: how to call servlet from JSP

I have a working servlet which returns a table in html format. I also updated the web.xml file according to the information I got from the previous message. My problem is how to correctly invoke the servlet in the JSF. I tried the following ways:
<jsp:include page="/report">
<jsparams>
<jsparam name="srcDev" value="#{Page1.srcDevice}"/>
<jsparam name="tgtDev" value="#{Page1.tarDevice}"/>
<jsparam name="format" value="complete"/>
</jsparams>
</jsp:include>
and
<frame src="/report?param1=val1&param2=val2" name="body" frameborder="YES" scrolling="YES" bordercolor="#999999" noresize>
both doesn't work.I am able to run the servlet within a html form. I just don't know what's the right syntax for calling the servlet inside a JSP page in JSF.
Can anybody help me?
Thanks,
Christine

Hi Christine,
This forum is exclusively for Sun Java Studio Creator related issues.
In case you are using Creator then you can find a sample application named RedirectionExample which makes use of a servlet and would be of help to you. You can find the tutorial on the following page:

How to send info from JSP page as email-body

Hi,
i have a JSP page that generates dynamically as a result of some query. I have a Button - "Send Email".
I want to send the information to the receipient thru email automatically on a button click,
All information is in the memory. How can we pick the info from memory and send it as a message thru email?
Pls help.
thanx & regards,
Shalini

create a servlet to send mail (use the JavaMail api) then Post the message to the servlet when you click on the button.
OR, put the message and any other data (like the email address) into the session, and then just call the servlet on click of the button, and have the servlet retrieve the information from the session.

How to catch ClassCastException from JSP page?

I get a ClassCastException within my JSP page and I know where my bug is. However, this classcastexception message is displayed in the browser and I want to catch this exception to also log it into my log file. But I can't find the place where to catch it: in my servlet's doPost() method I can't catch it - i tried it by enclosing the method body with try/catch but it isn't catched. I wonder if I can catch it at all or if this error is handled internally in the servlet engine?

It should only be displayed in the browser if you're not catching the exception in the jsp itself. If the exception is happening in the jsp, then there's no point in trying to catch it in the servlet.
What happens if you put a try-catch just around the actual code in the jsp? You could put it around the entire jsp, but that's not necessary.
One problem I've encountered in catching exceptions is if there are escape sequences within the try block, for example:
try{
//java code
%>

<%
//java
catch (Exception e)I'm not sure if that works or not, but to be safe, make sure you're not escaping from jsp within the try block.

Trying to trigger a servlet from .jsp page on combo box change

I have a jsp page with two combo boxes ( single select ).
Here's a snippet from the jsp page containing the code for the two combo boxes:
<form name="frmCountry" id="frmCountry" method="POST">
     <select name="selCountry" id="selCountry">
          <jsp:include page="/country" />
     </select>
</form>
<form name="frmCity" id="frmCity" method="POST">
     <select name="selCity" id="selCity">
          <jsp:include page="/city" />
     </select>
</form>
"country" and "city" are both mapped to servlets in the web.xml file
The country servlet successfully connects to the database and retrieves all countries
and populates the country combo box.
However, the populating of the city combo box depends on what country
is selected in the country combo box;
Here is a snippet of my code from the City servlet:
ResultSet rs;
rs = statement.executeQuery("SELECT City.countryID, City.id, City.name " +
               "FROM City " +
               "WHERE City.countryID = ( Country id ) " +
               "ORDER BY City.name");
Where ( Country id ) has to be somehow retrieved from the Country combo box
on the jsp page. Country id is actually the "value" property of each <option> in the
Country combo box. i.e.:
<option value="5">Portugal</option>
If it's not possible to retrieve the value property from the option,
I could always just use the Country name
So to reiterate, I need the City servlet to be called into action
any time a different country is selected in the country combo box.
I'm a newbie to jsp & servlets, so any suggestions much appreciated.

Cheers, I came up with a solution using Ajax, where I didn't have to change
anything in my servlets and only had to make minor changes to my jsp page.
I didn't want to use any javascript in my web app, but I guess Ajax
has addressed the issue of cross platform independence.

WL10 generated servlets from jsp pages

hi!
I'm looking for .java servlet files automatically generated from JSP (Weblogic 10). Do anybony know where can I find this files?
Thanks in advace,
Bartek

Well, Servlet and JSP both are server side technologies and both can be used in web applications. You can write web pages using both servlet and JSP. In fact, your JSP pages are converted to Servlet by container while serving requests. However, writing a JSP page is relatively easier and requires minimal Java knowledge.
When you will develop real world java based web applications you will find that you are writing more JSP pages than servlet.
In a typical MVC (Model View Controller) architecture a single servlet is used as controller and JSP pages are used to generate web content.

How to call servlet from jsp

How to run servlet and jsp in Eclipse

i am trying to run a jsp and servlet file in Eclipse its showing error in editor its self.

yep, eclipse can do that. I've never done it, but
Tomcat needs to have remote debugging enabled, which
means you need to use the tomcat that WASN'T
installed by an installer. don't ask me why, ask the
boys at Jakarta! eclipse attaches itself to the
debugger in some way or other. I dunno. there's a
book called Eclipse Distilled that only costs about
?10 or so and has a chapter on doing exactly this, if
you're using Eclipse for fairly advanced stuff like
this, I'd invest in a copy of that. well worth the
moneyTry [url http://www.eclipse.org/webtools/]WTP★ plugin (Web Tools Platform). I am using this plugin, and as far as I know it is free. You just have to install Tomcat normally, and configure WTP plugin to pointing that Tomcat. You can run, debug, do everything you want.
