Can Java reflect not only .Class file

Hi' i'm newbie in this topic, i'm really appreciate if somebody can help me..cos i'm really stuck in here...
My Problems are :
1. i want to ask about this, can Java reflect from .java file?
2. i'm using Eclipse IDE, i'm really interesting about how JTree or Package Explorer in Eclipse can always displaying update information about class structure? but .java files not compiled, how can? if Eclipse using reflection, .java files must be compiled first, correct me if i'm wrong?
The fact is Eclipse don't have to compiled .java files to get the update information about class structure and displaying in JTree or package Explorer...how implement like this?
what i mean like this :
ex : if i type int x = 100; (not only int, it could be anything else..) at the working files, JTree or Package Explorer in Eclipse can always update the informasion about class structure, but .java files not compiled..
i hope my question are easy to understand, i really need some help..
Thanks a lot..

hey, thanks for the answers, but i would like to ask :
1) Eclipse performs background compilation of the Java sources, then performs reflection on those temporary classes++ if i'm using this way, how about the performance? seems that it will be compiled all the time right?
2) Eclipse has access to the results of the Java source code parser, and can extract the information from the java syntax parser, before it gets to the compilation stage.++ how to implement this? what do you mean about java syntax parser?
do you know where i can find any article about this?
thanks a lot again...

Why require cap file why not only class file as in java

why do we convert .class to .cap file why not simply load the .clss file to the card

If Java Card has to accept .class file, it's certain
that JCVM developers are going to spend more and more
nights in their office.
Just kidding. I'm one of them.LOL :)
Put the CAP file converter on-card.

URGENT PLEASE:How can I run a a class file on the Apache server?

Hi Guys and Gurus,
I am seeking some favor all of experienced gurus, i.e.
How can I run a a class file on the Apache server? Can I run through an Applet?
How can I set Environment variables in Windows2000 Professional Environment?
Actually, I want to extract some records from a MySQL Database running on Apache Server. I wrote a program just to select the columns and show them. It is now a Class file, Now how can I run this class file from the Server???
The code is here
import java.sql.*;
public class RecordShow {
public static void main(String args[]) {
String url = "jdbc:mysql://localhost/myhost";
Connection con;
String query = "select mytable.column," +
"from mytable " +
"where mytable.column = 1";
Statement stmt;
try {
Class.forName("com.mysql.jdbc.Driver");
} catch(java.lang.ClassNotFoundException e) {
System.err.print("ClassNotFoundException: ");
System.err.println(e.getMessage());
try {
con = DriverManager.getConnection(url,
"myuser", "mypassword");
stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);
ResultSetMetaData rsmd = rs.getMetaData();
int numberOfColumns = rsmd.getColumnCount();
int rowCount = 1;
while (rs.next()) {
System.out.println("Row " + rowCount + ": ");
for (int i = 1; i <= numberOfColumns; i++) {
System.out.print(" Column " + i + ": ");
System.out.println(rs.getString(i));
System.out.println("");
rowCount++;
stmt.close();
con.close();
} catch(SQLException ex) {
System.err.print("SQLException: ");
System.err.println(ex.getMessage());
Please advise... THANKS

Ehm, I wasn't referring to you at all... read up,
there's a comment by jschell saying that CGI might be
easier/better for his purposes.
Yep.
I know PHP/Perl/whatever might be easier for some
purposes, but only if you happen to know them and want
to/are able to use them. Ok. But you aren't the one asking the question are you. And the person who asked the question seems to have absolutely no familiarity with Apache or applets.
So whatever they do they are going to have to learn a lot.
And that does indeed suggest that in all likelyhood they have not investigated the alternatives.
And for the vast majority of internet applications, especially with smaller projects (obvious this person is not working with a large team), using perl, or something besides java, is going to be the best business solution. It is simpler, and more secure (probably due to the fact that it is simpler.)
Since this is a Java forum, I
answer under the assumption that people have made a
choice one way or another to use a Java solution to
their problem, so I try to solve it in Java first, and
only when that fails (very seldom) do I turn to other
solutions.You approach problems by arbritrarily deciding to try to solve it in java first and only if you fail do you then look to other solutions?
My first step is to try to figure out which of the various avenues is going to cost less. (And a secondary, but non-trivial concern, is then to convince the customer that just because they have heard of a buzz word like 'enterprise bean' that it doesn't mean that is a cost effective solution.) We must come from different worlds.

Reflection - reading a .class file

I want to read in a .class file, and be able to use reflection to get a list of that class's methods. I'm using a JFileChooser to find the file, I just need to know how to use the output from the JFileChooser (a path to the file) to load the file into the program, and use reflection methods to create an appropriate Class object.

String fileName = fc.getSelectedFile().getName();

URL[] urls = {new URL(filePath)};
URLClassLoader cl = new URLClassLoader(urls);
Class c = cl.findClass(fileName);does not compile: "findClass has protected access"

HELP!!! java.lang.ClassFormatError: (Truncated class file)

Hello all,
I'm writing a ClassLoader and the funniest things are happening. If I load a compiled class for the first time after compilation everything is ok. Once I change the class and recompile it, it starts putting out java.lang.ClassFormatError: (Truncated class file). If I alter the changes back to normal and recompile. It works again. Is there some sort of buffer which keeps the once loaded class in memory, even after rebooting?
Please help, I'm at a loss

I refferd this url as a guid to write class loader and compiler.(actually same thing i copied
from there and change it's name Pmat1 to StringCompiler)
http://forum.java.sun.com/thread.jsp?thread=347467&forum=4&message=1439418
When I run this as a normal application, it is work well. Then I try to run it in a jboss and it will give the above error.
In here I Wote some EJBs and struts also and i called the methodds in the StringCompiler(Pamat1) class in a EJB. Thilina is
the name of the dynamically created calss and StringCompiler is the class that includes the class loader and compiler methods
as in the above url. qVoiceManagerEJB has a getvxmlString method. Whithin this method
i called required the methods in the String compiler.
Can u some body help me. Thanx in advanced for any help.

Win xp not opening class file.

win xp not opening class file.
Runtime.getRuntime().exec("cmd /C start c:/database/Myclass.class");
or
Runtime.getRuntime().exec("cmd /C c:/database/Myclass.class");
is this code wrong for xp ?

let me give some more information...
i have c:\database
in this folder i have 2 class...Myclass.class and Dbconnection.class
Myclass simply uses the database connection from Dbconnection.class , nothing else.
you see both of the classes are in the same folder(i.e c:\database) and there is no package
statement inside the code .
in command prompt if i do....
c:\database\java Myclass // this works fine
but i want this class to run at runtime, so i did like above and it is not running!!
what i am getting is a irritating windows file chooser is poping up and saying "class not
found...browse or search in web...etc etc"
Now my question is >
Q1 . how can i run that class at runtime ?
N.B
here is some brief idea abt classes
Dbconnection.java
DriverManager.forClass("...database....");
// only for database connection
Myclass.java
Connection con =db.getConnection();
//use this con and show results for ur database related queries.
}Q2. Can u plz tell those correct syntax how to run class file in this situation ?
i will try all possible solutions tomorrow.
thanx.

How to create a Jar with only class files?

Dear all,
I want to create a jar file with only classes.My class files and java files are in different folders under com .
say
com
in com there are two folders
folder 1 -- subfolder 1
folder 2 -- subfolder 2
like this.
If i want to create a jar file from com directory how should i give the jar command.Again my jar should contain only .class files.
Any help will be appreciated
Thanks
lekshmi

It doesn't work.Says "No such class or directory"
Any other way Or is it possible to do so?Read the link I posted and create the statement to make your structure. I was thinking you were inside the com directory but if you are above it you will need something like this instead:
jar -cf test.jar com\*.class com\subfolder1\*.class com\subfoler2\*.class
But either way don't just copy and past this. Think about what is does so that you can make it work for you.
Also, you might want to look into using Ant if you are going to be building this a lot.

Tomcat6 does not load class files from WEB-INF/lib/myjarfile.jar WHY???

I have placed my jar file in c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jar
But, after restarting tomcat6, when i try to import the class file contained in the myjarfile.jar in a servlet, it says
ProcessFileUpload.java:4: package test.test1 does not exist
import test.test1.*;
^It clearly tomcat's class loading problem.
As i unzipped my jar and placed the packagefolder structure to
c:\tomcat6\webapps\my-application\WEB-INF\classes\testand it works perfectly.
Anyone knows its workaround? please suggest if any configuration changes is required in tomcat or so.
Thanks.

Thank you gimbal2 . There was error in creating the jar file myjarfile.jar.
But, now I have created it again and placed it in place
c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jarand tried to use one on the Class file included within the jar to compile my servlet. But, still I am getting error at servlet compilation time. I want to place executable jar files in

Problem with:error: java.lang.ClassFormatError: Truncated class file

Hello, I created an simple applet writing "hello world". Now I would like to add *.class file to my serwer witch I've implemented on microcontroller P89C51RD2BN.
Serwer is programmed with hex file which is created after compiling C source files. In this case I converted .class file to array in C (using hexedit program). When I am (using IE ) browsing my serwer Html site is loading corectly and *.class file is send from serwer also corectly (define arrays are transfered corectly) but applet is not initiated. When I am runnig Java console I can see this:
error: java.lang.ClassFormatError: Truncated class file
When I am runnig the same site with the same class file on my PC everything is ok.
I would be greatfull for any help. Thx. (sorry for my English :P )

Not too familiar with native compilation, which I believe you are trying to accomplish here. It would appear that you don't have any problems running your applet, more or less running it after being converted to legacy code. Try the "native methods" forum under "Fundementals/Key Classes", this may be helpful. Sorry for not being too helpful.

Can JAVA import 3D Max Studio files?

I'm currently doing a research for my final project. The tittle is "Comparison Between JAVA 3D and Macromedia Director". Director can import 3D Max studio files, and i do not know whether can JAVA import 3D max Studio files? Pls help.... thanks

have a look at www.j3d.org , they have several different importers for 3d model file formats and might have one suitable..

How can I import not only apps from the old iphone to the new iphone, but also the content of the apps?

You can sync apps as you normally would, but I do not believe this copies over app specifc data (i.e. saved game status/scores).
You can always restore your new device with a backup from your old device.
