Can`t call Servlet form JSP in JDev 3.1.1.2

Even after correctly registering a servlet with "Web Object Manager", I can`t access it as an form action on JSP page, running latter from within JDeveloper (famous "Web-to-go URL not found" message).
Exactly the same configuration works for the old JDeveloper 3.1. There is no mentions in doc about any change here.
Is there any workaround or patch?

TooMuchConfusionException
If you have a class to be called from the JSP, place it in WEB-INF/classes directory under your web app directory... not in the lib directory.
I wonder how you manage to work on EJB...

Malay,
In your application servers' oracle_home\forms90 there is a file named "formsweb.cfg" configure that file with all parameters and application path also.

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!
- Park-

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.

Calling Servlets in JSP forms

Hello,
I'm trying to invoke in a html form (jsp file) a servlet, something like this:
<form method="POST" ACTION="validateLogin" ONSUBMIT="return ValidateForm(this)">
but the browser returns me this:
WTG-10109: Web-to-go could not locate requested URL
Web-to-go could not locate requested URL /validateLogin
the only way i have to run the servlet is replacing the ACTION field in form by:
ACTION="MyProj/_servlet_"
How can i change this?

You might want to look at using a Java Bean wrapper, this can be done automically using WebSphere. It creates what is called an access bean which the JSP imports.

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.
