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:

Very urgent: call servlet from JSP

Hello,
I'm facing a problem in invoking a servlet from a JSP having the JSF components.
The application has a text field to implement ajax for search functionality in the database .I have written a servlet to make the database connection and fire the querry.
Ajax implementation in a js file is called on every keyup event in the jsp file,and
a call is given to the servlet from the ajax methode.
The function in the js file is as follows:-
function getPersonByFirstNameXML( firstName ) {
    if (!firstName) {
        clearPersonByFirstNameXML();
    } else {
        var url = BASE_URL + "/servlet/get_PersonsXML";
        alert(url);
        return new AJAXRequest("post", url, "firstName=" + encode(firstName), processGetPersonByFirstNameXML);
}Im getting the myAJAX.status value as 500.
I think I'm not able to access the servlet properly.
what changes do i need to make in the we.xml file ?
and what should be the url to be passed.
Please provide me a sloution to the above problem as it is very urgent else if anybody is aware of a readymade JSF componet with search functionality freely available please let me know.
PS:
The 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:
http://developers.sun.com/prodtech/javatools/jscreator/reference/codesamples/sampleapps.html
is not available as stated in some of the suggestions by Author: mayagiri
Thanks for any help.
Abhi

the status 500 generally means either HTTP server internal error or that execution of CGI script or servlet aborted with error.
It can be reasonably supposed that the request reaches the servlet, ie. that "url" value points to some existing servlet, otherwise most probably the status value would be 404.
To test that the servlet is working i'd try to access it using some simple html page with form like this (with {BASE_URL} replaced by real value):
<form method=post action={BASE_URL}/servlet/get_PersonsXML>
<input type=text name=firstName>
<input type=Submit>
</form>

Problem calling servlet from JSP

Hi All,
I am running Tomcat 4.1.31 + Apache 2.0.54 for a web app. I have a jsp in a folder in my context root that is calling a servlet. My web.xml looks like this
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
<display-name>Web Application</display-name>
- 
- <servlet>
<servlet-name>Controller</servlet-name>
<description>Testing Servlets</description>
<servlet-class>servlets.Controller</servlet-class>
<load-on-startup />
</servlet>
- <servlet-mapping>
<servlet-name>Controller</servlet-name>
<url-pattern>/Controller</url-pattern>
</servlet-mapping>
</web-app>
and my jsp is as below:
<form name="loginForm" id="loginForm" action="/Controller" method="post">
<table border="1" cellpadding="5" width="300">
<tr>
<td>User Id </td>
<td><input type="text" name="userid" size="20" maxlength="15"/></td>
</tr>
<tr>
<td>Password</td>
<td>
<input type="password" name="passwd" size="20" maxlength="10"/>
</td>
</tr>
<tr>
<td colspan="2">
<input type="submit" name="submit" id="submit" value="Submit"/>
</td>
</tr>
</table>
<input type="hidden" name="action" id="action" value="login"/>
</form>
However, this doesnt work at all. Whenever I hit the submit button I get a 404 File not Found error.
I have to give the entire url starting with the context root in the JSP for the servlet to work. Is that how it is supposed to work?? I was under the impression that once everything is defined correctly, Tomcat will figure out that the JSP and the servlet belong to the same app and get it from there.
Can anyone help me please???
Let me know if anything is not clear enough.
Thank you!
amrutaa

Actually this is just an example app ... but I am going to have other jsps that will call the controller servlet ..
Thanks a lot for your help. I really appreciate it.
What stumps me is that the call to the servlet was working day before yesterday and yesterday it just wouldnt!
and I am sure I touched only the servlet in the meanwhile + restarted Apache as well as Tomcat.
Thanks again!

C:import tag - Query string while calling servlet from JSP

Hi,
From my JSP I am calling a servlet to write back to the response stream of the JSP. From the JSP i am trying to pass some values into the query string as follows
     <%
     String strGetParameters = "/servlet/MyServlet?path=" + strPath;
      %>
     <pre><c:import url="<%=strGetParameters%>" /></pre>In the servlet I try to get the path from the query string by using
request.getParameter("path")But in the servlet the query string doesnt have the "path" parameter that I added in the strGetParameters string (in the JSP).
Am i missing something? Do i have to use something else or do something else?
Any help is appreciated.

I've taken some time to do a simple test and it just works.

How to call reports from JSP/HTML application

Hi,
We have a web application developed in JSP, I'd like to use Oracle Reports writer to generate reports (Since our back office application is developed using Oracle forms and Reports - 6i).
I don't know how to place a request to Oracle Reports server and view the output. Can someone please help me with this.
Thanks in advance.
Best Regards,
Karthik

Hello Karthik,
You have a web application developed in JSP. In that you are calling Reports though URL through your JSP.
User views the source of the HTML page, in browser which is the result of execution of JSP. So Client will see the
HTML output, but not the real JSP.
Still if you donot want to hard code the user/password in file, have a form and ask client to enter user/password.
Or you can combine your JSP with other Java components , like Java bean or Servlets to get user/password at run time.
With Regards
Sachin

How to call servlet from applet residing in Oracle9i forms bean area.

Dear Members
I have an applet which is calls a servlet for database operations. If access this from a browser it works fine as the applet is signed. But When i place this applet in a bean area of Forms in Oracle 9i. It gives access control exception. Can anyone help me, as i feel this problem is with oracle9i forms.

Dear Members
I have an applet which is calls a servlet for database
operations. If access this from a browser it works
fine as the applet is signed. But When i place this
applet in a bean area of Forms in Oracle 9i. It gives
access control exception. Can anyone help me, as i
feel this problem is with oracle9i forms.As far as I recall - Oracle 9i forms is operating on a top of another special/internal servlet. I can't really recall, since I've been working with Oracle 9i forms 2 yrs ago. So total procedure looks like following:
applet -> Oracle 9i Forms servlet -> my servlet
instead of
applet -> my servlet
I think this is an actual reason why your signed applet can't work with your servlet.
Oracle 9i servlet has a number configuration files, I think among them you should change smth to get your construction working. Another approach would be to use servlet filtering before calling Oracle 9i servlet
Hopefully it will help

Calling servlet from a java program

Hi
I need to call a servlet's doPost() method from a java program. I have a specific situation, where I need to call servlet from a java program. DUring this call I need to pass a file and two string to the servlet. Servelt after receiving the file and string uploads the file to the server at a specified location. I am stuck up as how to call servlet from a java program instead of a HTML or JSP.
Can anyone help me to start with this.
any suggestion is welcome.

You have to establish a URLConnection with servlet from your java program.
URL servletURL = new URL("http://localhost:8080/Myservlet?str1=abc&str2=def");
URLConnection servletConnection = servletURL.openConnection();you can get the objectOutputStream
ObjectOutputStream oos = new ObjectOutputStream (servletConnection.getOutputStream());
oos.writeObject(your file object);-------------------------------------------------
In the servlet u can get the strings using request.getParameter("str1");
In the servlet u can get the strings using request.getParameter("str2");
file = new ObjectInputStream (request.getInputStream()).readObject()a lot of resources are available on this ...
hope this helps :)
