Embeddding WML in Jsp and running in TOMCAT?

I have written wml programs...and the required connection class to extract data from the database...i have also made a jsp page in which i have embedde the wml..as is done with html.
The problem is i am not able to run these wml programs in the browser?

Probably the Context named test has not been
created. Check on the admin console!I do this http://localhost:8080/manager/deploy?path=/test that's work but each time I stop Tomcat, when I restart, I have to do it test is not in the list after restart
An idea ?
Thanks,

How can I remove a file on server w/ my JSP app running on Tomcat 7 ?

First of all, I'm posting here because I found it the closest to java web development in the forums listing.
How can I remove a file on the server side with my JSP app running on Tomcat 7 ? I did it in a JSE app by changing permissions, but how can I do it for a simple JSP app ?
My code is
public static void excluirArquivos(String nomeArquivoExcluido) {
          File arquivoExcluido = new File (nomeArquivoExcluido);
          arquivoExcluido.setWritable(true, true);
          SecurityManager sm = new SecurityManager();
          try {
               sm.checkDelete(arquivoExcluido.getAbsolutePath());
               System.gc();
               if (arquivoExcluido.delete()) System.out.println("File '" + nomeArquivoExcluido + "' successfully removed.");
               else System.out.println("File '" + nomeArquivoExcluido + "' wasn't removed somehow.");
          } catch (SecurityException se) {
               System.out.println("File '" + nomeArquivoExcluido + "' can't be excluded. There is no permissions.");
     }And it always falls on the catch statement.

2. make sure the file is in fact not locked (for example, opened by another process)
3. use File.delete()
There is no guarantee that you can delete a file, you can only make an attempt. There can be any number of reasons, most if not all of them not related to code, that the deletion of a file does not work.

Does any one have any idea what could be the problem?
thanks a lot

seems the web Server code previously loaded a class only when it was used rather than when it was referenced,
ask your question in the tomcat-user mailing ! !!!

Opening a Powerpoint in JSP and run under Linux

Hi,
I need to have a JSP page that provides a link to open a powerpoint file and this JSP is to be run under Linux. When I try to click on the link in Linux to open the powerpoint, it gives me a lot of junk characters. Can somebody please help mi, thanks a million!

You have the mimetype for the HTTP response set to something other than what will make the browser start a powerpoint viewer and direct the content of the HTTP response to it.
In your jsp use the setHeader(String key,String key) method to set the value of "Content-Type" to the mimetype for powerpoint.
Of course the users must have browsers that are configured to launch a powerpoint viewer or plug-in. If you provide the correct mimetype and peoples browsers desn't have this, then they will get the "save to file" dialog box.

Needs to install JSP and related things!!

hi All,
I am new to java web-related areas though I am in Java platform for years. I want to set up JSP & Servlet development area with RedHat Linux OS and MySQL database with Tomcat server. Can u tell me what are the new versions of these are compatible with each other or with any website regarding this. Thanks in advance.
-bh_t_76.

Hi
You just need to visit http://jakarta.apache.org and download any version of Tomcat for Linux available freely. I am now aware about any other web containers for Linux platform althought I have worked with Jrun, Orion Application Server and Sun's J2EE Server on windows.
For the configuration, you can refer to any book for JSP and servlet. Most of the books contains details of installation, configuration and running of Tomcat.
I am in the process of learning JSP and servlets on Windows as well as Linux (I have Red Hat Fedora Core Project 1). So, I have told what I know till now. Hope that will help u.
Also, if you are interested in keeping touch with me for the development and learning purpose, so that we can share a few things about Java, I am listing my email address. it is [email protected]
All the best.

Unable to get the errorlogin.jsp to run correctly in a servlet.

I am attempting to read the users input using jsp and run the servlet LoginServlet to cross check the database to see if that are in the database. The problem i am having is that i can get the login working but am unable to get the errorlogin to run if the details are incorrect. Can anyone see where i have gone wrong? Thanks!
package Login;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;
public class LoginServlet extends HttpServlet {
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        try {
            try {
                Connection con = DBConnect.DbConnection.getConnection();
                Statement st = con.createStatement();
                String user = request.getParameter("t1");
                String pass = request.getParameter("t2");
                String strSQL = "SELECT username, password FROM users "
                        + "WHERE username = '" + user + "' "
                        + "AND password = '" + pass + "'";
                ResultSet rs = st.executeQuery(strSQL);
                String username, password;
                HttpSession session = request.getSession();
                while (rs.next()) {
                    username = rs.getString("username");
                    password = rs.getString("password");
                    if (user.equals(username) && pass.equals(password)) {
                        response.sendRedirect("next.jsp");
                    } else {
                        response.sendRedirect("errorlogin.jsp");
            } catch (ClassNotFoundException cnfe) {
                cnfe.getMessage();
        } catch (SQLException sqle) {
            sqle.getMessage();
}

How do You ensure that an exception is raised? Do You see any info in log files?
Not sure if this helps but try:
    response.sendRedirect(request.getConextPath()+"/errorlogin.jsp");In this case errorlogin.jsp should be put on the same level as WEB-INF directory is.

but i already set up the java compiler though i m getting this error. please help me.

You say you have set up the environment variables, but it is not working. You may have them set to the wrong thing. One common mistake is to point JAVA_HOME at the java/bin directory rather than just the /java directory.
Another set of eyes finds small mistakes in the variables that you might not spot yourself.
So please, post:
The values of these environment variables
The path to where the products are installed on your system (ie is it c:\java or c:\j2se1_4_2 or c:\program files?
I would take another close look at that JAVA_HOME variable to make sure of it :-)
Good luck,

How to setup my computer to run JSP and Servlets

I want to setup my computer to run JSP and Servlets.
What kind of Servers and other tool i need to install to run JSP and Servlets.
Plz, Help me to start my work on JSP.
Regards,
Usman Ali

hello
JSP and servlet is web programming, may be little bit different to development local application.
1st, you should have two computers: one is server and the other is local workstation. This server should have a static IP address, that other people can go into your server. Workstation is any computer normal you use it.
2nd, you need to setup your server in: OS(linux or windows 2000), web server (jrun, apach or Tomcat etc. ), as well as install JDK, servlet.
3rd, your local workstation just use as programming editor and open a browser to testing, anytime you write your code, then ftp to server to test.
Reality, you have many technical thing to solve, eg setup web server etc. However, you can write your source code and test it, then open to outside people.
hope to helpness, if anything don't uderstand, you can post again or send email to me [email protected] Since I just have setup this configuration in my university for my project.

JSP and Tomcat Problem

Folks,
My apologies if this is off-topic for this forum, but I've been having this problem using Tomcat and JSP. I'm fairly new to Java.
Basically, I'm writing a webapp that uses servlets and JSP together. The servlet and backend classes all compile fine. Now, basic frontend page is called Console.jsp, and one of the commands that it runs is <%@ page import="DJUser">
Here's the problem: Console.jsp is in $CATALINA_HOME/webapp/
DJUser (and the rest of the classes I'm using) are in $CATALINA_HOME/webapp/WEB-INF/classes
When I attempt to run Console.jsp I get this error:
exception

I've been scouring the web for a while, and I can't really find anything on this. I'd appreciate any help you could give me.
Thanks!
Dylan

Put the DJUser java file in a package (say com.myClasses) and recompile. Then put the DJUser class file under the WEB-INF/classes directory in the proper package structure (WEB-INF/classes/com/myClasses/DJUser). Stop and restart the server to pick up the new classes. Make sure to change the jsp import statement ( <%@ page import="com.myClasses.DJUser">)

How to call jsp /servlets running in different web application in tomcat

hello all,
i have 2 web applications(Charts and Reports) in the same tomcat,i want to call jsp/servlets running in the Reports webapp from Charts webapp.how do i achieve this.
thanx
ravi

You can also use getContext(String context) in the ServletContext class to get a request dispatcher.
Using the above example it would be :
// in a servlet in the charts webapp
ServletContext context = getServletContext();
ServletContext reportsContext = context.getContext("/reports");
RequestDispatcher dispatcher = reportsContext.getRequestDispatcher("/path")
dispatcher.forward(request, response);Just note, that depending on your server's configuration getContext(...) might return null.

help please...Jason,
Simplest way "in my opinion":
1. start weblogic Server. You can use Server with examples. This domain
is already configured, so You will not need any domain configuration tasks.
2. open weblogic administration console using browser
http://localhost:7001/console/. Log in.
3. On the left side choose Deployments -> Web Application Modules
4. Click "Deploy a new Web Application Module"
5. Find folder with Your application. Mark it and click Target Module.
6. Define Application name and click Deploy
7. If deployed successfully, Your application should be accessible at
http://localhost:7001/YourApplicationContextRoot

JSP file is too large to run in TOMCAT 4.1.18

When updating TOMCAT from 3.2.3 to 4.1.18, I got an error message .
After trying, I find TOMCAT 4.1.18 will crash if the .class file is too large.
(These files will run well in TOMCAT 3.2.3)
Test data:(bye adding the code "" into JSP file)
binary code is 209 KB (214,477 ��) -->ok.
binary code is 216 KB (222,079 ��) -->ok.
binary code is 224 KB (230,270 ��) -->false.
The web shows message as below. After I downsize the crash JSP.
It will run perfectly.
But I hope to keep the source "completely".
How could I do for it?
HTTP Status 500 - Internal Server Error

A Simple solution,
Modulize this JSP page. If you have 5,000+ lines of code in your jsp page, well you might want to consider moving alot of this logic into Beans and or multiple jsp pages and do jsp:includes to the other pages.
I personally recommend that you review your design and break it down into multiple Beans. There really shouldn't be too much code in your JSP pages.
Look into Struts or Web work to get a better understanding of what I am talking about.
Look into MVC designs and Model 2 designs.
I hope this helps.
