Send some atributes from a Servlet to a JSP program

Hi all,
          I am quite new to JSP programming and am facing a problem. I have a
          Servlet code which is supposed to send some attributes to a JSP, which
          will display the attribute that has been passed through the Servlet.
          the Servlet code to do so is,
          request.setAttribute("emailtxt","emailNewTxt");
          RequestDispatcher rd=request.getRequestDispatche("/emailChangeSuc.jsp");
          rd.forward(request,response);
          on the JSP side, I am reciving this attribute in the following way,
          <body>
          <%@content_type="text/html"%>
          <%! String emailTxt=HttpSession.getAttribute("emailNewTxt");%>
          and am displaying the value in this way
          <b><%=emailTxt%>
          but I am getting an error
          "non-static method getAttribute(java.lang.String) cannot be referenced
          from a static context
          probably occurred due to an error in /emailChangeSuc.jsp line 9:
          <%! String emailTxt=HttpSession.getAttribute("emailNewTxt");%>"
          Please help me solve this problem.
          Thanks in anticipation,
          Rajiv.

          First of all, you put the attribute into the request, but you're trying to read
          it from the session. Change it to "request.getAttribute(...".
          Second, your compile error is stating that the "getAttribute()" method of
          HttpSession is not a static method. If you really needed to reference the
          session, it would just be "session". Changing to "request" as in the first
          point, will avoid this problem.
          Third, remove the "!" from the scriptlet which declares and sets the "emailTxt"
          variable. That makes it declare an instance variable instead of a local
          variable. That will cause numerous problems with this.

Is there an easier way to send an email from a servlet?
Thanks
tzaf

It's not a matter of "easier way" to send mail from servlet...you are missing a crucial element in your code: authorization to send mail. You need something like this (some of which you have already so note what is different):
        Properties properties = new Properties();
        properties.put("mail.smtp.host", String3 );
        properties.put("mail.smtp.dsn.notify", "SUCCESS" );
        properties.put("mail.smtp.host", "mailservernamegoeshere");
        properties.put("mail.smtp.auth", "true");
        MyAuthenticator auth = new MyAuthenticator();
        auth.setUser("user whos account you want to use goes here");
        auth.setPassword("user password goes here");
        Session session = Session.getDefaultInstance( properties,auth );Here is the auth class:
class MyAuthenticator extends Authenticator {
   protected String m_strUser     = null;
   protected String m_strPassword = null;
   protected PasswordAuthentication getPasswordAuthentication() {
      return new PasswordAuthentication(m_strUser,m_strPassword);
   public void setUser(String strUser) {
      m_strUser = strUser;
   public void setPassword(String strPassword) {
      m_strPassword = strPassword;

I want to send a response from the servlet and then call another servlet.

Hi,
I want to send a response from the servlet and then call another servlet. can this happen. Here is my scenario.
1. Capture all the information from a form including an Email address and submit it to a servlet.
2. Now send a message to the browser that the request will be processed and mailed.
3. Now execute the request and give a mail to the mentioned Email.
Can this be done in any way even by calling another servlet from within a servlet or any other way.
Can any one Please help me out.
Thanks,
Ramesh

Maybe that will help you (This is registration sample):
1.You have Registration.html;
2.You have Registration servlet;
3.You have CheckUser servlet;
4.And last you have Dispatcher between all.
See the code:
Registration.html

How to display outsream from a servlet in a JSP

I wrote a jsp file to call a Servlet, then want to display the result from the servlet in another jsp file. Anyone can give me possible solution or an example to illustrate it.
Many thanks in advance.
the file that call servlet in a jsp is as follow
<form method="POST" action="myservlet">
<table>
<tr>
<th align="center" colspan="2">
Enter The query words
</th>
</tr>
<tr>
<th align="right">query words:</th>
<td align="left">
<input type="text" name="querywords" size="60">
</td>
</tr>
<tr>
<td align="right">
<input type="submit" value="Search">
</td>
<td align="left">
<input type="reset" value="Reset">
</td>
</tr>
</table>
</form>
............

I would suggest that you use the Servlet to retrieve the data you are after and store it in the session. Then forward the user onto the JSP page where it can retrieve the object from the session and present it to the user in a formatted view.

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!

Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!

hmmm, I dont really like using JSP programming, u should be using JAVA..
the way to do it is:
Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:
<input type="text" name="firstName" value="<%= u != null? u.getFirstName(): "" %>">
this is the real programmers way,,,

Challenge forwarding from a servlet to a JSP

Redirecting information from a servlet to a JSP
Hello Everyone,
     I am processing the contents of a html form using a servlet. After processing the
information received and storing it into a javabean I am trying to pass control onto a jsp for
display. At this stage the jsp does not display as desired due to a URL challenge. The URL
which references my jsp is:
http://localhot/ferngully/prefset.jspThis url has been designated to the jsp page 'prefset.jsp' by the application specific web.xml
file (...I am using Tomcat 5!), the relevant contents of which follow:
<servlet>
     <servlet-name>PreferenceSet</servlet-name>
     <jsp-file>/prefset.jsp</jsp-file>
</servlet>
<servlet-mapping>
     <servlet-name>PreferenceSet</servlet-name>
     <url-pattern>/ferngully/prefset.jsp</url-pattern>
</servlet-mapping>If I access the page with the afore mentioned URL it displays correctly. However the URL which
is returned to the browser after the servlet has forwarded control to the JSP is:
http://localhost/ferngully/ferngully/PreferencesThe following form markup is used to access the servlet:
<form name="form1" method="post" action="ferngully/Preferences"> I know that I have mapped the servlet correctly because the servlet performs it's programatic tasks happily :)
I am using code within the servlet to forward control to the JSP, and I believe that this is the crux of my challenge.
The code for the servlet is listed below.
package userpreferences;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class PreferencesServlet extends HttpServlet
     public void init(ServletConfig config) throws ServletException
          super.init(config);
     public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
          doPost(request, response);
     public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
          String url = "/prefset.jsp";
          ServletContext servCont = getServletContext();
          RequestDispatcher reqDispatch = servCont.getRequestDispatcher(url);
          reqDispatch.forward(request, response);
}I believe that the above highlighted code section is responsible for my challenge. I have tried changing the String url to "/ferngully/prefset.jsp",
however there was no improvement in functionality.
Can somebody please explain to me how I can go about directing the control of this process from the servlet to the jsp correctly? Particularly
how I can go about making the url returned to the client correct for accessing the jsp page? Do I need to delete the mapping entry for the
jsp page in web.xml? I am new to servlets & jsp so any help will be much appreciated.
Thanks
Kind Regards
Davo

3. >The following form markup is used to access the servlet:
<form name="form1" method="post" action="ferngully/Preferences">Question 1:
     why do you specify your contextname in action attribute again ?
     General funda about urls:
     When you have an index.html loaded through http://localhost/index.html, then a link in that html whose url is,
     1. say, preferences.html (no forward slashes preffixed or suffixed) would load the html from the same folder.
     2. say, /ferngully/prefences.html, would attempt to load a html from the ferngully folder that is a sub-directory
of your web-application
     3. say, /ferngully/prefences.jsp, would attempt to load a html from the ferngully folder that is a sub-directory
of your web-application
     When you have a servlet whose url-pattern is set to intercept requests, it would intercept requests that have that
pattern it is defined to intercept in web.xml (for example all the above requests in 1,2 and 3 would be intercepted
by a servlet whose pattern is ferngully/*)
     Now if your action is not a specific resource (.jsp or .html), something like /preferences, this would map to a url
/ferngully/preferences. (for which a resource should be defined in web.xml - either a servlet or a jsp)
However the URL which is returned to the browser after the servlet has forwarded control to the JSP is:
http://localhost/ferngully/ferngully/PreferencesTell us the url of the original html
I know that I have mapped the servlet correctly because the servlet performs it's programatic tasks happily :)Tell us the url-appetrn of the servlet that intercepted your request
Particularly
how I can go about making the url returned to the client correct for accessing the jsp page?The url in the browser is always the request url, you cannot change it to the url of the jsp even which rendered the page
through a fwd from the servlet.
Do I need to delete the mapping entry for the
jsp page in web.xml?Not necessary. You can access the jsp directly from the servlet while forwarding by
1. specifying the exact path to the jsp. For example if the jsp is under a folder called jsps, your request dispatcher
url ought to be /jsps/prefset.jsp
2. specifying the jsp's url-pattern as specified in web.xml
Questions Contd
2. Why does the url pattern have to have a .jsp suffixed.
From your code
<url-pattern>/ferngully/prefset.jsp</url-pattern>It could equally well have been
<url-pattern>/ferngully/prefset</url-pattern>And then your servlet would have to forward it to ("/ferngully/prefset")
2. Your jsp-file mapping is in this form
<jsp-file>/prefset.jsp</jsp-file>This assumes that the jsp is in the top-level folder of your web-application and not under
any sub-directories. Correct ?

Trigger workflow by sending XML-Message from a servlet

Hi Developers,
I am currently evaluating WLPI and followed the tutorial provided by BEA. Now
I try to create a Workflow which is triggered by an XML-Message that is sent by
a servlet to WLPIs JMS. The 'Programming Client Applications' gave me a hint of
how to do it. But some parts are missing. Can you recommend a book or tutorial
which goes beyond the tutorial or give me a hint on that?

Looks like the problem is on the client side (MSXML) because I can flawlessly send half-megs XML files from a Servlet to a browser or a java.net.URL

Send Get request from a servlet.

Is it possible to send parameters from one servlet to another by using get? I don't want to use Post because the servlet recieving the parameters already has the post method doing something else. Any ideas?

May you can use the RequestDispatcher for your use.
Doc:
public interface RequestDispatcher
Defines an object that receives requests from the
client and sends them to any resource (such as a servlet, HTML file, or JSP file) on the server.
The servlet container creates the RequestDispatcher
object, which is used as a wrapper around a server
resource located at a particular path or given by a
particular name.
This interface is intended to wrap servlets, but a
servlet container can create RequestDispatcher objects
to wrap any type of resource.
It send the requset with the same methode to an other resource. You don't have care about the parameter.
Your code could look like this:
protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException
        RequestDispatcher dispatcher = getServletConfig().getServletContext().getRequestDispatcher("/next");
        dispatcher.forward(request, response);

Session is lost when going from a servlet to a jsp

Any help would be greatly appreciated.
          I can sucessfully go from my jsp page to the Servlet. When in the servlet I have a service method where I place the information from my form on the jsp on a bean. Then I do a session.setAttribute("aBean", aBean) to place the bean in the session. Then do a req.sendRedirect("my.jsp"). Watching it in the debugger, when we leave the servlet our session is cleared and when we do a jsp:usebean to get the bean session from the session it creates a new bean so all the information is gone that was there before. here is my usebean tag where we are getting it from scope,
          <jsp:useBean id="aBean" scope="session" class="com.MyBean"></jsp:useBean>
          Thanks, Trucker

<jsp:useBean name="helper" scope="session" class=".."/>
          <jsp:useBean name="helper" scope="session" type=".."/>
          ·class="package.class"
          Instantiates a bean from a class, using the new keyword and the class constructor. The class must not be abstract and must have a public, no-argument constructor. The package and class name are case sensitive.
          ·type="package.class"
          If the bean already exists in the scope, gives the bean a data type other than the class from which it was instantiated. The value of type must be a superclass of class or an interface implemented by class.
          If you use type without class or beanName, no bean is instantiate
          In your case you already instantiated the bean “com.MyBean” in servlet and you set bean in session scope. But you are not accessing that bean from servlet. Instead of that you are crating a new bean instance by using class attribute of <jsp: useBean>. So if you want to access the bean already created in servlet you should use type attribute instead of class in <jsp: useBean>. So you have to change your code as follows.
          <jsp:useBean id="aBean" scope="session" type="com.MyBean"></jsp:useBean>
          Then you will not lose the bean created in servlet.

Trouble forwarding request from a servlet to a JSP in OAS 4.0.8.1 on NT

The OJSP release notes state that:
"Servlets and JSP cannot coexist as the same application" and "Requests cannot be passed between two separate applications."
Does this mean that my attempts to use the
the servlet RequestDispatcher to forward a request to a JSP are futile? If so, is this a problem that will be fixed in the future? I would like to use this feature!
This is the code (based on a sample from Sun's JSWDK 1.0.1) that doesn't work:
servletToJsp.java
import javax.servlet.*;
import javax.servlet.http.*;
public class servletToJsp extends HttpServlet {
public void doGet (HttpServletRequest request,
HttpServletResponse response) {
try {
getServletConfig().getServletContext().getRequestDispatcher("/jsp/jsptoserv/hello.jsp").forward(request, response);
} catch (Exception ex) {
ex.printStackTrace ();
I am able to use the <jsp:forward page="/servlets/servletToJsp" /> directive to go from a JSP page to a servlet (across two OAS Applications) and I also can forward a request via the dispatcher from one servlet to another in the same OAS application.
Any help in this area would be appreciated. Thanks.

I'm using OAS 4.0.8.1
You mean servlet to JSP does not work and JSP to servlet works for you????Yes - but I've only tried very simply examples.
That's different from my understanding. If you are using OAS 4081, both cases should not work.
The problem you mentioned will be fixed in future release of OAS.That's good to know - thanks!

Executing an executable from a servlet or a JSP

Is it possible to call an executable from a servlet. Say I have a client server application and I want to start the client application from a servlet. What is the best way to do that?
I know normal Java applications can use the Runtime to run an executable. Can a servlet do the same? What are the security implications, considering that the servlet will be accessed from a browser?
Thanks for your help.

A servlet is executed on the server, not the client. The client receives a response from the servlet which is usually plain text formatted as HTML and/or javascript.
So can a servlet use the Runtime class? Sure, but on the SERVER, not on the client. Hence, the executable will need to be on the webserver, not on the client machine and it will execute on the webserver, not on the client.
Maybe, your HTML formatted response can include an <applet> tag to trigger the browser to download an applet that may have access to call an executable. Maybe a trusted applet?

Cannot send some emails from the address book. Comcast says it is not a server problem.

Keep getting this message when trying to send a group email from the address book -"The size of the message you are trying to send exceeds a temporary size limit of the server. The message was not sent, try to reduce the message size or wait some time and try again. The server responded: 4.1.1... temporary failure."
Comcast has checked it - the issue is not the server they say. This problem just started 4 days ago. It appears other people have this problem on the thunderbird forum and it has not been resolved yet.

The Comcast server is issuing the error message. Have them explain how this is not their problem.
