Could not able to RUN Java Programs in JRE 1.5.08

hi
I am using Jdk 1.5.8.
I don�t have any problem in compiling the files.
but i could not able to run the program through windows cmd prompt.
Say name of the java file is newFile (no packages).
When i try to run the program by using java newFile it raises a ClassNotFoundException.
it s the same case when try to set any JDBC drivers ..
is there any problem in my class path settings? Please help me out to fix this problem

if your current directory is not in the classpath,you should include it in the classpath.
To do that you can include .(dot) to your classpath variable.

I would really appreciate if some one can help solve the above issue.

That is always a classpath issue. Fix your classpath so it uses the J2ee.jar. If you are using an IDE you will have to look up how to add JARs to the IDE's classpath, which is usually not the same as the system classpath.

I am not able to run a program,please help?

hi everybody,
i am getting run time error when trying to run this program, what's the wrong with that
i copied the mysql( mysql-connector-java-5.1.11-bin.jar) driver to the following:
C:\Program Files\Java\jre1.6.0_05\lib\ext
here is the code:

System.out.println(
"java with mysql");
try {

Class.forName("com.mysql.jdbc.Driver");
String url ="jdbc:mysql://localhost:3306/mysql";
Connection con = DriverManager.getConnection(url,"root", "555");
System.out.println("URL: " + url);
System.out.println("Connection: " + con);
stmt = con.createStatement();
stmt.executeUpdate("CREATE DATABASE JunkDB");
stmt.executeUpdate(

This is a sub-optimal solution. Renaming a jar file to remove version information can cause problems later. How will you know the version for which you check documentation, bugs, etc? Also, the root directory of your file system is not the best place to put java archive files. It can get pretty crowded for a complex application. I suggest you create, for your project, some directory where third-party jar files can maintained. We do this for each project.

Not able to run a program to extract news from news channel websites.

Let me start with stating the fact that I am a super greenhorn, so please be ultra elaborate with the answers .
This is my code, I copied it from Mr. Alvin Alexander (http://alvinalexander.com/java/edu/pj/pj010011?). I am trying to use it to extract news from news channel websites.

Also, when I try a local server URL, the output screen goes blank, which I guess is due to lack of Text on the local URL. So, the little research that I did, made me believe that the code not running on external server was due to firewall on the server side. Please help me run it. Also : I work on a proxy network.( if that has something to do with this).
P.S : Advanced gratitude for any assistance.

any decently secured server would reject such a blatant attempt to steal its content.

Not able to run jsp on content server

Hi,
I am trying to create home page for the website using file type as jsp. File creation was successful but when I try to run the web page, instead of launching the web page its asking to save the file. Can any one let me know whats the problem. Is there any setting needs to be done for jsp pages.
Thanks,
Abhijit

if you do a view source is the jsp outputting any HTML at all?
can you tell if the page is loading and just not displaying?
You might also want to check the server output.
To see that you can selecte "System Audit Information" from your Admin Menu option (you must be logged in with sysadmin privileges to see this)
Click "view server output" link on the menu bar.
warmly,

Not able to run java programs

Exception in thread "main" java.lang.NoClassDefFoundError. I have set the path and classpath but in user variables. And defined main in my programs. But programs are only compiling not running.
Please suggest me.
What do I do?
Edited by: Ram-Murthy on Apr 10, 2008 2:23 AM

Make sure your main is static.
public static void main(String [] args) {}

Why am i not able to run this program ??

When i exec a single process it works fine but when i try to execute array of commands i couldn't it complies but doesn't execute any 1 of the commands.
Please let me know
import java.io.IOException;
class RunTime
public static void main(String raja[])
Runtime r = Runtime.getRuntime();
Process p;
String[] commands = { "notepad","calcic","mspaint"};
System.out.println("Executing processes please wait........");
try
int commandslength = commands.length;
for(int i = 0 ; i < commandslength ; i++)
p = r.exec("commands");
catch(Exception e)
System.out.println("Cant proceed furthur ..");

Instead ofp = r.exec("commands");dop = r.exec(commands);Next time please paste your code between [code] tags with the help of the code button just above the edit message area.
It makes the code MUCH more readable.
Regards

I'm not able to run a simple Hello Program in java

I have just now installed jdk 1.3.1_2.
I have set the path and class path.
I'm able to compile the class without any errors but am not able to run the program.
when i say java Hello(after compiling Hello.java), i'm seeing the following error:
Exception in thread "main" java.lang.NoclassDefFoundError:Hello
Thanks in advance in this regard

Hmm..
Okay.. set aside any import or package stuffs.. lets say about a simple HelloWorld program which is called Hello.class. It resides in c:\, which means the full path is c:\Hello.class.
Make sure you got one of your path as c:\jdk1.3\bin(assuming you are using jdk 1.3).
If you are in the same directory as Hello.class, which is c:\>, you can execute the class file by typing:
C:\>java Hello
If you are not in the same directory and you wishes to run the class file, example you are in directory temp now:
C:\Temp>java -cp C:\ Hello
So the cp set will be just c:\. Hope that answers your question somehow.. well... if I never intepret it wrongly.

I am not able to run the java Program

Hi All,

Can u any body help me out...... I have also update the latest version of JRE but still my problem is not sloved.
Thanks & Regards,
Ravi

Make sure you take package structure into account.
If you have say
package testing.things;
public class Test
public static void main(String[] args)
System.out.println("World Hello");
}in file Test.java, you compile it with (assuming your current working directory is at the folder in which the source file is located).
javac -d . Test.javaand run it with
java testing.things.TestThe -d . option creates the output at the current directory (with a folder structure matching your package structure).

Am not able to run the java program - pls help

1. I installed java in the below path
     c:\program files\java\jdk1.5.0
     c:\program files\java\jre1.5.0
I set the path in
     User variable i. variable name: path
          ii. variable value: c:\program files\java\jdk1.5.0\bin
when I compile it in command prompt-applying javac ? it performed successfully-shows
options like ?g create all debug info, -g : new Generate no debug info etc.,
But am not able to run the file. It shows error msg.
2. I specified the same name for file name & class name.
3. Java <class name>
     Exception in thread ?main?java.lang.NoclassDeffoundError: <class name>
4. Java ?cp <class name>
     Unrecognized option: -cp.<classname>
     Could not create the Java Virtual Machine
5. Java ?classpath . <classname>
     Exception in thread ?main?.java.lang.unsupported classversionError: <classname>
     <unsupported major.minor version 49.0
          at java.lang.classloader.defineclass0<native method>
          at java.lang.classloader.defineclass<unknown source>
               --and many listed below?
6. Java ?classpath c:\program files\java\jdk1.5.0\bin <class name>
     Exception in thread ?main?java.lang.NoclassDeffoundError: <class name>
7. I re-installed the java, but still the problem continuing.
pls help... its very urgent

Is the java class you compiled/calling in the default package? If it is not, you will have to call it by the fully qualified name.
e.g.
package com.mycompany.myproject;
public class MyClass {
    public static void main(String[] args) { }
}This would be called as "Java com.mycompany.myproject.MyClass" and must contain a main method with signature as above.
You would have to call this from folder where the compiled classes are located. If using package, you would call from directory at level of top most package so com folder in this example as Java will look at each package name in qualified name and try to traverse directories with those same names to get to .class file matching class name specified. To avoid this, your newly compiled .class files must also be in your classpath.
Hopefully that helps.

I have followed the Apple Support instructions I did it 3 times and this message always appear: "The program can't start because MSVCR80.dll is missing from your computer" and 'Error 7' but still not able to run iTunes. Anyone have a suggestion... Please!

I have followed the Apple Support instructions but these 2 errors always appear: "The program can't start because MSVCR80.dll is missing from your computer" and 'Error 7' but still not able to run iTunes. Anyone have a suggestion?

Try completely removing and reinstalling iTunes and all related components; you may need to do this multiple times. It won't normally affect the iTunes library, but that should be backed up anyway.

Not able to prompt errors.
Hi,
Your error message are not displaying because u does not made Message-Resoucrce property file (Resource Bundle) when you make it .
give it entry in
struts-config.xml
<message-resources parameter="ApplicationResources" />
and
define key and corresponding error message to key in this ApplicationResources i.e
#Error Resources
label.search.ssNum=Plz Enter correct ssNum

I am not able to run JSP program
