Can i Use java Class

Can any help, can i use java class in
froms 6 or any one have designed form
of progress bar please help me

Thanks for your reply...
Actually the task is quite simple... It requires me to do a better interface for a tomcat server folders...
For example, users are free to access
http://apache.oss.eznetsols.org/jakarta/tomcat-5/v5.0.12-beta/
to download the tomcat... However, its index may not nice and easy for browing.. Therefore, the task requires a new dynamic page to access this server folder, and get all file names under this folder, anlaysis whether it is file or directory..and finally get its path....
It is quite easy to do a JSP page, but I don't know whether it is possible to do by using JavaScript .... Although JS is running in client side, the user/client also can access the tomcat folder, why not JavaScript?
Thanks a lot!

Than how can i get java class by using it's class file?

Hi
After compilation of a java program, it creates a class file.
After getting class file suppose class file has been deleted.
Than how can i get java class by using it's class file?
Thanks in advance.

get a decompiler and run your class file through it--I'll assume you want the source code back and that you are not trying to recover a missing class file by attempting to use the class file that is missing--if it's missing, then I've not a clue on how to get it back by using what is already missing.
BTW: many of your compilers have source control--if it does, just restore your missing file.

Need help with tomcat 5.5 and using java classes

hey there,
i am trying to set up tomcat 5.5 on my computer at home and have sucessfully done so. i have been trying to use Java classes inside my JSP files however tomcat thows an internal servlet error as follows:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 144 in the jsp file: /order.jsp
Generated servlet error:
ProductList cannot be resolved to a type
An error occurred at line: 144 in the jsp file: /order.jsp
Generated servlet error:

i have the classes located as the setup tutorial recommends (root/WEB-INF/classes/) and still nothing works. i would appreciate any help anyone can give.
thanks,

Which tutorial are you following?
As of java1.4, all classes must be in packages for them to work in Tomcat. This means your beans and servlets too.
Put your beans in a package, and then recompile them, and put them in the right place.
eg
package com.mypackage
public class MyClass ...
once compiled would go into WEB-INF/classes/com/mypackage/MyClass.class
Are you using Product and ProductList classes in scriptlet code?
Have you imported them with a page directive
<%@ page import="com.mypackage.Product, com.mypackage.ProductList" %> ?

How to use JAVA class in C++

Hi people,
is there anyone who knows how I can create and use JAVA class in C++ code. Example I have one JAVA class which works with database.
One of the methods from this class returns XML string that represent result set. How to create instance of this class inside of C++ and have possibility to call this method.

Hi, I'm also curious how to solve this.
My problem is that I call a DLL from C++ that returns several values (e.g. function(a, b, c, &w, &x, &y, &z); )
and I want to create a java class object that can be used to store these values so I can return 1 object
Below I've written an abstract of the code
Can someone help me with the parts in <> ??
Thanks!
Sander
JNIEXPORT jobject JNICALL Java_nativeF(...a,b,c...)
   int w,x;
   float y,z;
   C_DLL_Function(a, b, c, &w, &x, &y, &z);
   //<Create Java Class 'Data' jobject>
   //<Call Data.setvalues(w,x,y,z) >
   return jobject;
...in java...
class Data
private int jw, jx;
private float jy, jz;
public function setvalues(int w, int x, float y, float z)
    jw = w;
    etc...

Can't use "java" command

I just can't use the java command...
The paths have been set and everything should work...
If I just type "java" (without the "") I get:
Usage: java [-options] class [args...]
(to execute a class)
or java -jar [-options] jarfile [args...]
(to execute a jar file)
where options include:
-client to select the "client" VM
-server to select the "server" VM
-hotspot is a synonym for the "client" VM [deprecated]
The default VM is client.
-cp -classpath <directories and zip/jar files separated by ;>
set search path for application classes and resources

And if I type "java Oper" (It compiled normally and worked on my school computer) it gives me this error:
Exception in thread "main" java.lang.NoClassDefFoundError: Oper
It works everywhere but on my computer...
Oh, and I have Java Builder 3 University Edition installed. When I use that to compile + run my program, it works perfectely... I just can't use "java" in command prompt. I have a Windows ME.
Another note, this may be related: I can't use certain Java applets on my computer, like the IRC applets for example. I tried it on both Netscape 7.01 and Internet Explorer 6.0.2800.1106. It displays the same kind of error, the Exception in thread "..." java.lang.NoClassDefFoundError: ... .
And I've already tried uninstalling + reinstalling. Any other suggestions?

start -> run -> cmd
(if it doesn't open command prompt, then try command instead of cmd)
once you have reached command prompt, then you change to some empty directory where you would like to create java or class files. (use cd command for that)
once you have reached that directory, type: notepad Hello.java
(it should open notepad, and it should prompt you a question if you want to create file Hello.java (since it didn't excist) ... click yes)
in notepad type the following:class Hello {
public static void main(String[] args) {
System.out.println("Hello");
}once you have written that into notepad, then click File and choose Save from there.
now you may close your notepad.
now go back to that command prompt and type in command dir Hello.*
it should lis you all Hello.* files, and Hello.java should be one of these.
now, when you have seen that in your current directory a Hello.java does excist, you may type javac Hello.java
if it does compile whitout any errors then everything is OK so far.
type again dir Hello.*
now you should see two files, Hello.java and Hello.class
if you now saw that Hello.class was in the current directory, you may type the following command: java Hello
it should display a String "Hello" on your screen.
if it doesn't work, then you have problem with java not working from commandline (some classpaths are wrong or unset or smthng similar)
if you suspect that something doesn't work, then always test it with simplest task.

HT1338 I need to bulk upload to Auctiva (auction software) but Java was disabled on my computer. I have 10.5.8 so does this mean that I can't use Java? If not, then is there a workaround to be able to use the bulk uploader from Auctiva?

I need to bulk upload images from iPhoto to Auctiva (auction software) that will then be posted to eBay; however Java was disabled on my computer some time ago due to "known issues." I have 10.5.8 so does this mean that I can't use Java? If not, then is there a workaround to be able to use the bulk uploader from Auctiva? As it stands now, I have to upload photos individually which is super time consuming.

You can re-enable it for special purposes, opposite of disabling it...
Disable Java in your Browser settings, not JavaScript.

Using java class from JSP page

I have a class that connects to the database and return the result in form of array of objects, now I wrote a tester and I was able to print the result on the console but when it came to JSP how can I use this class I am a bit confused, how can I declare an array of objects and save the result that comes from the class method
note: my class is not a bean it is a service class that contain methods to retreive different information from the database.
I would apritiate any help but please make it in sequence for example declaring an array to hold the result then call the method that returns the array of objects..etc
please help, I am really confused and don't know what to write
thank you

You can access a class in the same way as a bean, after all a bean is just a class that follows a set of rules.
You need to put your classes in packages to access them.
I have 2 packages, params and DTO. I set the class that returns the Data Transfer Object, or array of objects up as I would a bean
<jsp:useBean id="DTO" scope="request" class="params.DTO" />
I think you skip the above declaration and access it directly in code using
params.DTO();
but setting it up as I would a bean allows me to simply use
DTO();
DTO is the class that passes back the array of objects.
Objects themselves I have in a seperate package, also called DTO (sorry if this is confusing, made sense at the time :-) ) You dont need them in seperate packages, just helped me keep DTO objects seperate from business logic classes......
Now before I use params.DTO() I declare a variable of the Object type DTO() returns
<%! DTO.workSheet[] ws; %>
So, ws is the object type that will be returned by params.DTO()
Then to get my array of objects back from params.DTO() :-
ws = DTO.workSheet(day);
or if you dont like the bean declaration
ws = params.DTO.workSheet(day);
You need to put your packages under WEB-INF/Classes when using Tomcat
So I have
Tomcat 5.0\webapps\myApplication\WEB-INF\classes\params
Tomcat 5.0\webapps\myApplication\WEB-INF\classes\DTO
Under which reside the classes

How can we use java variable in javascript code on JSP page?

How can we use java variable in javascript code on JSP page?
Pls help

Think about it:
JSP/Java is executed on the Server and produces HTML+JavaScript.
Then that HTML+JavaScript is transfered to the client. The client now interpretes the HTML+JavaScript.
Obviously there's no way to access a Java variable directly from JavaScript.
What you can do, however, is write out some JavaScript that creates a JavaScript variable containing the value of your Java variable.

Can I use Java Creator 2 with old JRE/JDK 1.4.2_07??

I am planning to install new Java Creator 2 but I am having JRE and JDK 1.4.2_07 and I am using mysql 3.23.55 and I want to integrate it.
Currently my OS is Windows XP SP2 platform with processor Intel Centrino 1.4 and RAM 256 MB... I know the ram is not sufficient and i am planning to upgrade it.. but the problem is can i still remain to use the old JRE and JDK 1.4.2_07 and i am also using mysql 3.23.55... all the driver and engine are out to date but can i still use it and integrate it with java creator 2?
The questions are:
1) Can I use Java creator 2 with those old engine?
2) What java compiler or development tools i can use to develop java standalone application?
Thank you

When the jar file is expanded within Eclipse, it shows that the mail.jar file is built with 1.5.0; I think? Here is the header contents of the MANIFEST.MF file, note "Created by."
Manifest-Version: 1.0
Implementation-Version: 1.4
Specification-Title: JavaMail(TM) API Design Specification
Specification-Version: 1.3
Implementation-Title: javax.mail
Extension-Name: javax.mail
Created-By: 1.5.0 (Sun Microsystems Inc.)
Implementation-Vendor-Id: com.sun
Implementation-Vendor: Sun Microsystems, Inc.
Specification-Vendor: Sun Microsystems, Inc.
SCCS-ID: @(#)javamail.mf 1.6 05/12/09
This is causing problems, because anytime I try to use this file, I get signing errors. I have several Web Services built by BAE and Plumtree that are running on 1.4.2; and therefore I am stuck with 1.4.2. I did try to remove the SUN_MICR.* files, thinkning it would resolve the signing issues, but then that caused other problems. I can provide you with code that demonstrates the problem.
Is there a place where I can get a mail 1.4 jar file built with 1.4.2? that would most likely solve my problems.
