Manually call action servlet from JSP

Hi All,
I have a struts form that uploads a file (which works perfect with no problem). IN this form i have a <html:submit> button.
My problem is, if I have a field say Employer field; and i would like to search the employer address as soon as the focus leaves the employer text field and display it in the same form. I wrote a javascript onchange="javascript:getEmpaddress(this)"my javascript is:
function getEmpaddress(objForm) {
document.objForm.action = "/searchForm";
document.objForm.submit();
return true;
}this form is not submitting... anyone having a clue on this?
PS: for the the upload part, i have written seperate action & form
for the employer search i worte seperate action & form
and registered them both in my struts config file

You can call the servlet via RequestDispatcher (include or forward method):
RequestDispatcher dispatcher=getServletContext().getRequestDispatcher("/servlet/ServletName");
dispatcher.include(request,response);In the request you can store the data with setAttribute methode.
And in the servlet you can get this data via request.getAttribute methode.

Problem in calling a servlet from JSP

Hi,
I am trying to call Loginservlet from my UserLogin.jsp and the code I used in jsp is:
<form method="post" action="/LoginServlet name=form1>
All the components are here
</form>
And I have also checked web.xml. It looks like
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>servlets.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServletServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>
But still when I submit the Jsp page, I am getting error which says the resource "servlets.LoginServlet" is not available.
I am using TOMCAT5.0 server and eclipse IDE.

change
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>servlets.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServletServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>to
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>servlets.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/LoginServlet</url-pattern>
</servlet-mapping>and check wid
<form method="post" action="LoginServlet" name=form1>& make sure you have placed LoginServlet.class in <WEB_APP>/WEB-INF/classes/servlet/ folder
Hope this might help :)

Hi,
You have not said if your servlet is in a package in which case which one.
you need to add the '/servlet/' to the href so it becomes
'/servlet/test1'.

Calling a Servlet from a JSP within Portal Portlet

We've created a JSP that calls a Servlet when the form is submitted. The servlet handles the request, does some basic processing and then forwards back to a JSP. This works fine outside of Portal.
What needs to be done in order for this to work within a portlet in Portal? We can get to the first JSP which is in a portlet, but as soon as we click the submit button (which tries to call the servlet) we get the basic page not found error. We need to click the button, go to the servlet and have the servlet forward back to our portlet.
I know this is not the ideal way of using Portal however...
Any ideas?
Thanks!

I was wondering is there any way I can call a servlet from jsp? There are two scenarios here
1 - if the jsp is currently being executed/evaluated on the server, then you can use <jsp:include> to "call" a servlet, or <jsp:forward> to cancel the jsp and transfer the control to the servlet.
2 - if the page is already loaded and running in the client, then the only way to call a servlet is making a HTTP request as from any other html page. Jave code does not execute on the client, so you have to use html/javascript at that point.
Calling a servlet within another servlet.
lets say one servlet maintains all dynamic html. I call this servlet from another servlet to create a dynamic page and then insert values into it.Close, but the standard pattern is the reverse of that. What normally happens is you retrieve the values to put in the page, and then call the page, passing in those values. Thats why often you get a servlet/actionbean getting called, which then forwards to a JSP to display the result. The servlet/bean loads all the values required into scope, and then the JSP presents the data.

Error in accessing servlet from JSP

Hello everybody,
When I access a servlet from a JSP page,I am getting the following error message :
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I am using Weblogic 7.0 and my web.xml code is as follows:
<web-app>
<servlet>
<servlet-name>TestServlet</servlet-name>
<servlet-class>TestServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>TestServlet</servlet-name>
<url-pattern>/TestServlet</url-pattern>

I am accessing the servlet from a javascript function in my JSP page.
I am quite new to the Java technology. So any help in this regard would be highly appreciated.
Thanks in advance,

The form action event is in a javascript function. I am sorry I mentioned that I am accessing this servlet from JSP. Actually,this servlet is accessed from an HTML document.
The following is the javascript code:
<script language="javascript">
function lfnCallNext()
     alert("In the function");
     frmMain.method="POST";
     frmMain.action="/TestServlet";
     frmMain.hidChoice.value="GetList";
     frmMain.submit();
</script>
And this function is called from an hyperlink as follows:

Did you package your JSPs in a WAR and your EJBs in a JAR and package the
          WAR and JAR in an EAR? That is how to do it in 6.0. Works well.

How to call a servlet from another servlet

hi everybody,
i have a problem, i have to call one servlet from another one.
Everything works on my pc, but when i install the application on the customer's server i got an error about an Uknown URL followed by the name of the machine.
Wjat i do is the folloqing :
String urlString = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+"/"+servletName;
URL url = new URL(urlString);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
the variable servletName is the name of the servlet i have to call.
Is there another way to call the servlet ?
All the servlet are installed in the same server.
Any suggestion ?
Cheers.
Stefano

Sweep is correct about requestDispatcher being another approach for inter-servlet delegation; the only issue that i recall with this approach is that it defaults the method of the destination servlet to the one it was called from...for example, calling servlet2 from within servlet1.post() resulted in the dispatcher attempting to utilize servlet2.post() - i believe that i searched for a parameterize solution to no avail :( (ended up handling the request by placing a "fake" doPost() in servlet2 that simply called servlet2.doGet())
however, if your application is functioning correctly on your pc/webserver then the problem may be external to servlet communication (e.g. client webserver's ports not configured or blocked, missing runtime classes, etc.)
my suggestion would be to set aside the programmatic concerns for the moment - what is the response if you open a browser on a client's machine and access the URL in question (i.e. http://clientserver:port/stefanoServlet)? If it will not respond to access in this manner then it certainly won't when your application calls for it.
It's possible that there is a coding error but, given the info supplied, i'd start examining the environment, first. Let us know if you have any luck with the test i recommended or not (please provide abundant detail). Or, if you've found the solution then you may want to post back with a quick blub so the next person knows how to escape the trap.

How can i call a servlet from a servlet ?

Hello,
Can i call a Servlet from within a Servlet ?
and is it "right thing" to Do ?
Thanks

JMO, but I wouldn't do it like this.
Don't have a remote object like a servlet doing database queries for your app. That will mean TWO network hops for every query if the database resides on another machine. The network is the biggest bottleneck you've got.
Write a JavaBean that does the database stuff for you and just have the first servlet instantiate it when it needs it. A Bean has a better chance of being reused, too. Write a TableGateway or DAO for your object.
Or write an EJB to do it.
The only time I've done a servlet-to-servlet connection like that was for one servlet running in a DMZ that would authenticate a user and then forward the request to another servlet running inside the second firewall.
I wouldn't encapsulate database query logic in a servlet like that. JMO - MOD

Hi ,
Its easy to call a WS from jsp what you can do is this. Think in manner that u will be keeping the client classes on a particular container, then in same container you can refrence the classes and can invoke service through a jsp..this works in my case.. it depends what kind of client do u want to create may be static or proxy or DII

Calling a servlet from a servlet?

Is it possible to call one servlet from another servlet?

You should use servlets to process requests. If what you're asking for is to execute a piece of logic within a servlet before its finished processing the request, then you should consider using a regular java class instead of a servlet. If you just want to send the request information to another servlet you can use getRequestDipatcher().forward(..) method. Keep in mind that by doing so you'll interupt the current servlet.
