Java program in Jsp

Dear Friends,
I am new to jsp
Can embed java program in my jsp page ?
my java program contains outputstream, printwriter etc.,
can i put those in jsp program ?
please help me.
Thanks in advance

Of course you can. That's the whole point of JSP... Hence the name "Java Server Page".
JSP is designed to allow Java to interact with your page. You can instantiate classes and do anything you could normally do from within a non-jsp java app.

  • JSP codes for running a JAVA program

    hello...
    does anyone know the JSP codes for running a Java program from my web page?? i mean i already have my java program compiled... and i just want this java program to run in the background when I click on a button or a link...
    Any idea about this?
    plz advice..
    avi

    yes... u r somewhat right... but this runs on Jakarta Tomcat...
    i'm using the Apache Http Server together with the ServletExec AS which enable the Apache server to run JSP..
    I've created a package where i've put my classes...
    WEB-INF/classes/tbd(package name)/my classes
    and i've added.. package name.. in my java program..
    and then in jsp... i've written..
    <%@ page import="tdb.*"%>
    <jsp:useBean id="exec" class="tdb.textdb" />
    <%exec.convert_data();%>
    but when i run the page it says the package does not exist...
    can anyone tell where to place the folder WEB-INF so that it can run fine?

  • Need help with jsp that uses a java program

    Hi, sorry for my english but i am italian.
    I've got a problem: i use java builder and i have a java program(this program has got a main and includes libraries) about graphich on tree, this program visualizes these trees and makes operations on these.
    Now i must use JSP so that a client can see this program (this program is on the server) and can interact with it.
    I can't use applet.I must use only jsp.
    Who can tell me how can i start???
    Thanks.

    If you are not allowed to use an applet, then you are limited by what can be achieved with HTML in a browser.
    You would have to figure out how to render it with HTML, then program your jsp to write out this html programatically.

    I realize now that it may have been wiser to post it here, but I have some replies already and it makes more sense just to inlcude the link.

  • Calling jsp page from a java program

    Hello,
    Is it possible to call a JSP page from a java program? If so, please let me know how it is possible.
    I have a JSP page that inserts 10 records in a database based on the attribute given to the page. When the java program is executed all the 10 records need to be inserted.
    The JSP page is already running fine in Tomcat.
    Thanks and Regards,
    Prasanna.

    MVC has applied the standard of seperate your view , model and controller. I believe nobody will insert data from jsp page,better practice should be inserted from your database layer, normally is like DAO layer. so you should pass your data from jsp to your backend.
    hopefully it's help u

  • Java code in jsp source files is not allowed in ojsp.next mode.

    Hi,
    I’m working on WC Spaces Customization library “com.acme.custom.webcenter.spaces.war”. From time to time, when I deploy the library to WC Server, it errors out.
    weblogic.management.DeploymentException: Cannot undeploy library Extension-Name: com.acme.custom.webcenter.spaces, Specification-Version: 11.1.1, Implementation-Version: 11.1.1.2.113 from server WC_Spaces, because the following deployed applications reference it: webcenter-rest.war, spaces.war, sharepoint-servlet.war, webcenter-rss.war
    If I try to login the Spaces, I get “Java code in jsp source files is not allowed in ojsp.next mode.” Should I stop the Spaces server before the deployment? In this case, other people won’t have accesses to Spaces? The deployment error doesn’t happen all the time.

    I don't think that this error is based on ojsp.next mode. The first error I see is that the application can't be undeployed. After that you get the 'ava code in jsp source files is not allowed in ojsp.next mode.' error. As you said this only happens sometimes which also point to an other problem and not to the jsp error.
    Have you ask this on the {forum:id=354} forum?
    For me it's more a deployment/redeployment question.

  • How to detect that i am already running a java program

    hi
    i am writing this java program. my problem is i don't
    want to run more than one program at any time, so i
    need a way to detect whether I am already running the program whenever I want to run the program.
    Is there any way to do this in java ?
    thanks for you help

    Look at this thread:

  • Compiling / Running a Java file in JSP

    Hi,
    ok, I have a jsp page, which we will call page 1. Once I go to that page, I all I want it to do is compile a certain file.java, and then run the file.java. The user doesn't actually know that this is going on in the background. Page 1 automatically redirects the user to page 2 (also a jsp page).
    The java program that I created (that was previously compiled and ran) creates a special javascript file. After running the file.java in page #1, the java file creates a javascript file that will be used in page 2 to display a tree node (group of information).
    so, right now, I'm trying to figure out how to write the jsp code that will tell how to compile and run a java file. I was thinking about using javabeans before, but I think you HAVE to actually display the contents of the java file into the jsp (I think). Anyhow, thanks for the help!

    sorry about being ambiguous before. What I mean by
    running a java file was that I already created a java
    file. I don't want to hava my java statements inside
    the jsp file. I just want the jsp file have a command
    in it that would call a java file, tell the java file
    to compile and run. All the jsp file would do
    (hopefully) is just give commands for a seperate java
    file to compile and run. Thanks again for any help!Ok, so this other java file has some entry-point method, like main(), right? So call it...
    <%
    YourJavaClass.main(appropriateArgumentsGoHere);
    %>
    or better yet, it's an object you can use:
    <%
    YourJavaClass x = new YourJavaClass();
    x.callSomeMethodHere(withAppropriateArgumentsHere);
    x.callAnotherMethodMaybe();
    %>
    You don't need the jsp file to "compile" this java file, you'd already have compiled it beforehand, and it's class bytecode needs to be in your classpath (on the server side) of course.

  • "at" UNIX Command in Java Program

    Friends,
    1. "at" command in UNIX execute Unix command at a scheduled time. 2. For each user there will be a table maintained internally which can be accessed by "at" with "-l" argument.
    3. A mail will be sent to the owner with the output of the commands as a message.
    I tried to run the "at" command of Unix in JSP, which gets succesfully executed in Oracle 10g App Server container (Installed in Solaris machine). I have tested the successful execution of command with the log file. But I haven't got any mail for the output. If anyone had any idea, please help me.
    The code I have wtitten is
    Runtime rt = Runtime.getRuntime();
    Process proc = rt.exec(new String[] {"sh","-c","at 2115 Dec 7 < /export/home/usr1/abc.sh"});
    InputStream stderr = proc.getErrorStream();
    InputStreamReader isr = new InputStreamReader(stderr);
    BufferedReader br = new BufferedReader(isr);
    String line = null;
    logger.info("<ERROR>");
    while ( (line = br.readLine()) != null)
    logger.info(line);
    logger.info("</ERROR>");
    int exitVal = proc.waitFor();
    logger.info("Process exitValue: " + exitVal);
    My doubts are:
    1. Who is the owner of the output of "at"command, which gets executed under Oracle 10g App Server container?
    2. If no one is the owner, then where will the output of "at" command will go?
    3. Is there any other way to execute "at" command of UNIX in java program? If so, then please help me.
    Thanks in advance.

    filestream I have to ask - what's a chav ?
    I have doubts abut what it is :-)
    Seriously though, what is that an abbreviation for?
    That's a new one to me.
    http://www.chavscum.co.uk
    chavs are roughly analogous to rednecksI wouldn't use that analogy. While both may lack certain social graces, rednecks typically don't receive ASBOs.
    Chavs favor small cars with lots of bling whereas rednecks are likely to drive a pickup or a large sedan.
    Chavs have pitbulls in their yards (gardens), rednecks an '84 Mustang LX on cinder blocks.
    etc, etc.

  • How to read files on server from a java program?

    Hello,
    I am fairly new to JSP programming. I have an issue with reading files. I am trying to call method of a normal java file from a jsp program. The method I am trying to call does some IO operation on Files. I have the files in the same directory as my class files on server that is in WEB-INF/classes folder. In my java program, I am giving just the file name to open because the files and the classes are in the same directory. But this is not working.
    What exactly should I do to read a file from a java program, that is running on the server?
    Any help is appreciated.
    Thanks,
    Krishna

    String realFilePath = application.getRealPath("/WEB-INF/myFile.txt");
    File fileToOpen = new File(realFilePath);
    out.println(fileToOpen.getAbsolutePath() + ": exists? " + fileToOpen.exists());in this case "application" is a reference to the ServletContext.
    It is an implicit variable in a JSP. In a servlet:
    ServletContext application = getServletConfig().getServletContext();
