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 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.

According to J2EE standards:
The web appl directory structure should be:
WebAppRootDirectory
|
|---html, jsp, images etc
|
|---WEB-INF---
|---classes--
|---lib
|
|
1) Make sure WEB-INF is in capital letters
2) Place all ur beans in classes dir or sub-directory in
classes
3) In Tomcat place WebAppRootDirectory in webapps
directory

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.

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.

Calling Classes From JSP pages

I am importing an application specific class in a JSP page and calling it
          (Win NT). It compiles the servlet successfully but cannot appear to find the
          class during execution.
          I have tried placing the class file / jar file containing the class in
          CLASSPATH environment / weblogic JAVAPATH variable / weblogic ServletClasses
          directory .. so far without any luck.
          I would appreciate any suggestions.
          Regards,
          Pradeep


Put it in WEBLOGICCLASSPATH variable. And make sure it is only in
          WEBLOGICCLASSPATH , nowhere else.
          Cheers - Wei
