How to clear old class files cached in JVM

JVM stores old class files in its cache even after the corresponding files have been deleted from the database. This causes a conflict if a new file is saved with the same name as one that was deleted earlier causing old data to be fetched and not the new one.
am using the following line of code to load the class file :
Class.forName(className, false, this.getClass().getClassLoader())
please help
Thanks - N

Why are you trying to do that?
Dynamic Classloading(reloading) has a meaing only on "application container" like WAS.
Not appropriate for normal applcation.
Focus on enhancing your application logic and algorithm rather than wasting your brain on difficult and meaningless things. Applying some flexible design patterns wouldn't suffice?
Anyway, Sun provides wonderful and simple custom classloader sample.

Anayzing tomcat source(which is downloadable) is another approach.

Tomcat Web-server uses old .class files

Hi Friends,
My Tomcat webserver uses old .class files. The problem persists even if I delete old class files. The new ones are formed but then if i again recompile, the new-old ones are used :)
Am I doing something wrong????
Please suggest!!

I have experienced this problem before as well. Tomcat seems to cache compiled class files for better speed. To get Tomcat to reload class files that I've recently recompiled here is what I do:
1. Go into the Tomcat server administration area (http://localhost/admin)
2. Choose the context that is using the classes that you want to reload (from Service / Host)
3. Make sure reloadable is set to true
3. Click save, and then commit changes
Hope this helps, but if there is a better way to get Tomcat to use the most recent class files I would love to hear it!

How to convert java class file version without decompiling

Hi,
Oracle R12.1.3 i am having illegal access error while try to access the class file version Java 1.3 uses major version 47,So how to convert the class file version without using decompiling.
Current java version is 1.6.0_07
Is there any tool or API for converting class file version?
Thanks,
Selvapandian T

Beside this I wonder where you get your error from since AFAIK 12c comes with java 1.6.
Well wonder no more!
OP isn't using Oracle 12c database.
They are using Oracle R12.1.3 - which is the E- Business Suite.

How to convert a class file to exe file and how to cteate a class file to d

how to convert a class file to exe file

Hi Bhaskarq,
Hi,
It is not at all possible.
But it is a really worst method.
Please go through it.
This is a very common question asked in the comp.lang.java newsgroup. Its often useful to have an
executable application when deploying your
applications to a specific platform, but remember to
make your .class files available for users running
Unix/Macintosh/other platforms.
Microsoft provide a free system development kit (SDK),
for Java, which includes the jexegen tool. This
will convert class files into a .EXE form. The only
disadvantage is that users need a Microsoft Java
Virtual Machine (JVM) installed. If your target
platform is Win32, you can either redistribute the
virtual
machine, or raise the level of your system
requirements, to include Windows 98, or Windows 95
with
Internet Explorer 4. Systems matching these
requirements will already have a copy of the Microsoft
Java Virtual Machine installed.
Note : You must specify all of the class files your
application needs (except for standard java packges)
as a parameter, so if you have third party libraries,
you'll need to include them as well. You can use wildcards * though, and you don't need the original source code.
Also please see this Forum which will give a good idea

How to get the .class file for the extended Controller .java file

Hi,
I did the below steps.
1. Created New OAWorkspace
2. Created New project
3. Imported the page .xml file
4. Added new .java file by extending the controller class
5. Added code in the .java file.
6. Ran the .xml file
As I copied all the folders from Unix box, the page was opened.
But My question was where can I see the .class file the extended controller. It's a .java file. How to compile and get the .class file for this .java file. If I get this .class file, I can go to the page and click the personlize page. and change the Controller name to the new path by ftp ing the new class to the cust.oracle.apps.pos.changeorder.webiui.
Please let me know how to create the .class file.
Thanks,
HP

All are Java files are stored in JDEV_INSTALL_DIR:\jdevhome\jdev\myprojects\
In your case the path java would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myprojects \cust\oracle\apps\pos\changeorder\webui\
AND
Once you compile the java file in Jdeveloper, Class files get generated @ below path
In your case the path of class would be
JDEV_INSTALL_DIR:\jdevhome\jdev\ myclasses \cust\oracle\apps\pos\changeorder\webui\

Is it possible clear the class loader cache programatically?

Hi,
Is it possible clear the class loader cache programatically?

By the cache do you mean the loaded classes? If so, you can do that by discarding any pointer you have to the class loader and creating a new class loader. ...though I wonder why you would need to do that...

Caching of old class files

Ok, I have a problem with oracle which appears to be that it is caching an old version of a class file. I get a class not found exception but the thing is the package that the error message is refering to doesn't even exist anymore and isn't refrenced in my code. I've verified that the class's being deployed aren't old versions as well and tried restarting the server as well as redployments of my application. Does anyone know where this caching maybe occuring? I know this happens sometimes in weblogic and you have to go in and manually delete the compiled class files from a weblogic directory.

Hi,
The caching of classes happens in the application-deployments/<you_application_name> folder. Just delete this folder and start OC4J.

How to clear old data?

Greetings,
My first question: how do I locate and clear out old, unnecessary files and folders? I'm thinking about browser cookies, temp files, etc.
Second question: is this even necessary on a Mac? I just switched from PC recently, and I am still trying to learn the Mac way. I know that with a Windows PC it is CRUCIAL to clear out cookies, the "temp" folder, and various other folders from time to time, because Windows constantly saves things you don't need. I just freed up 5GB on my work PC by cleaning it up in this fashion.
So: is this kind of "maintenance" necessary on a Mac, and if so how do I do it?
Thank you!

Hello DePombal, and a warm welcome to the forums & Macdom!
Different Maintenance is required on a Mac, if it were me, I'd give a try with Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
After installing, reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
As long as you don't have a USB connection in tandem with a UPS, which can cause problems. If so, disconnect it first.
The other thing is to have a Cloned backup, Get carbon copy cloner to make an exact copy of your old HD to the New one...

Again,HOW to conver a .class file into .java one?

sorry , but Can't u send me a specific link for downloading this "Java decomplier"??
coz I found my self in something called (jad decompiler) with lots of versions and this is confusing
and Is that mean, that there's a decompiler which can convert the .class file into .java one?
and thanks alot man.....u help me always!
(I'm still begginner in java)

Just to emphasise what yawmark said...
Decompiled java code is NEVER going to be as clear as well-written original java source code. The decompiler can see what the compiled code does but not why or what it means, so the source code that the decompiler produces is going to be ugly and hard to read. Decompilers are really only useful for experienced programmers who know what to infer, how to read between the lines...
If you need help writing something, then you're better off looking at tutorials. In tutorials the code will be well-commented.

My server still taking old class file

Hi,
I have got a J2EE application.
In that I have to modify a Java file.
I made the required changes and check it in the local test environment and find that it is working fine and the changes are reflecting in my application.
Then I copied the class file in the main server and deploy the server(i m using oracle9i server) .
After successful depletion ''THE CHANGES WERE NOT REFLECTED IN THE APPLICATION ".
I found the latest class file is copied in the application(checked the class file using D-Complier).
MY PROBLEM IS : WHY THE SERVER IS NOT TAKING THE LATEST CLASS FILE ??
IS THERE ANY PROBLEM OF WEB-CACHING ??
kindly advise how can i rectify it.
keep smiling.....
Debasis

The last response is correct. You have to stop the server and start it again to reflect the changes in the class file. Only the JSP files can be changed dynamically while server is running as the container compiles it if there is any change in the file. All other files need a server restart.
Thanks

How to edit a ".class" file? Anyone?

I hope someone can help me with this...
Someone gave me a class file to put into my applet. However, I'm wanting to go into the class file and change a few things around. However, I've done just about everything to try to find a way to go into the code of this file to do some changing, and I can't find anything to do it with! I've tried Netbeans and Visual Studio .NET, but it doesn't work. Maybe I'm doing something wrong. Does anyone know how to go into the class file and change it?
thanks soo much..

Someone gave me a class file to put into my applet.
... Does anyone know how to go
into the class file and change it? And why can't you ask "someone" for the source? Or ask them to modify it for you?

How to call a class file in a jsp without deploying anything in j2ee

Hi,
I am new in J2EE. I have some jsps, which I configured using web.properties(documentroot=c:/jsp/). I am able to get
those pages by the web browser. I have some import statements in some jsps, now I
am trying to access those page but it is failing, it says
org.apache.jasper.JasperException: Unable to compile class for
JSPD:\j2sdkee1.3\repository\pradip\web\_0002fLogin_0002ejspLogin_jsp_0.java:1:
Class com.gui.UPMGuiGlobalConstants not found in import.
import com.gui.UPMGuiGlobalConstants;
Actually I have not deployed any class file or jsps.. Now my question is can I access
these jsps without deploying anything, like can I put my .jar file in any j2ee
directory(like lib or anywhere else, I already tried after putting in /lib) and restart the
j2ee and use it. So how can I call a class file from a jsp without any kind of
deployment?
Please send me the reply as soon as possible.
Regds,
Pradip

After you put the jar containing the class to import into the WEB-INF/lib directory, you still need to include it in the jsp.
Putting the jar into the lib dir, will make it available to the vm, but as in any other java class, you still need to import it into the class, that the jsp will be compiled into.
And you do that by putting
<%@page import="com.gui.UPMGuiGlobalConstants" %>somewhere near the top of your jsp. (well you don't need to put it there, but it good style ;)
That should do it.
