Hi,
starting a couple of weeks ago, we get the following error(s) when running applications from a network share. We don't know what causes this, we are not aware of any major changes in our network infrastructure or client/Server configuration. We did upgrade
a lot of machines to Windows 8, but the issue also occurs on older Win7 computers.
We figured out a workaround though: The applications run fine when launching from a FQDN share (like
\\share.domain.Company.com) and only cause problems when running from
\\share directly. They have worked fine for years without FQDN though.
Any ideas?
Error Details (the Kind of error differs greatly):
# 1 #
Log Name: Application
Source: Application Error
Date: ...
Event ID: 1005
Task Category: (100)
Level: Error
Keywords: Classic
User: N/A
Computer: vmDEV
Description:
Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program XYZ
because of this error.
Program: XYZ
File:
The error value is listed in the Additional Data section.
User Action
1. Open the file again. This situation might be a temporary problem that corrects itself when the program runs again.
2. If the file still cannot be accessed and
- It is on the network, your network administrator should verify that there is not a problem with the network and that the server can be contacted.
- It is on a removable disk, for example, a floppy disk or CD-ROM, verify that the disk is fully inserted into the computer.
3. Check and repair the file system by running CHKDSK. To run CHKDSK, click Start, click Run, type CMD, and then click OK. At the command prompt, type CHKDSK /F, and then press ENTER.
4. If the problem persists, restore the file from a backup copy.
5. Determine whether other files on the same disk can be opened. If not, the disk might be damaged. If it is a hard disk, contact your administrator or computer hardware vendor for further assistance.

>>The applications run fine when launching from a FQDN share
It sounds like a DNS suffix issue. When this issue occurs, please try to ping share on the client, then check if the corresponding IP address is correct. If the IP address is wrong, please adjust your settings of DNS to make sure that the client can resolve
the share correctly.
If it's very hard to change the settings of the DNS for some reason, as a work around, we can add the entry into the clients' hosts file.

For WebLogic 5.1, where should I put my class files for my JavaBeans?
With JBuilder4, I have built an application with JSP and a few Java Beans (Those JavaBeans are instantiated in those JSP files). There are no EJBs. The package name is called 'onlinetrade'. I have tested the application on JBuilder's web server, it works pretty well.
Now I am moving this application to WegLogic 5.1. I have encountered a problem with WebLogic 5.1
and do not know where I should place my JavaBean class files --
Originally, the JSP files for my application are in package path-- ..onlinetrade\jsp
and the class files for my beans are in the package path -- ..onlinetrade\jsp\bean\*.class
Now, with WebLogic 5.1,
1) I have put my JSP files in
C:\weblogic\myserver\public_html\onlinetrade\jsp
2) I have created subdirectory and put my bean class files in
C:\weblogic\myserver\classfiles\onlinetrade\jsp\bean
When I started weblogic and the first page - login.jsp page can be up and accessed. But when I login and forward to another JSP page called 'controller.jsp', where a bean is instantiated, I got the following error
Compilation of 'C:\weblogic\myserver\classfiles\jsp_servlet\_onlinetrade\_jsp\__controller.java' failed:
C:\weblogic\myserver\classfiles\jsp_servlet\_onlinetrade\_jsp\__controller.java:210: cannot access jsp_servlet._onlinetrade._jsp.registerBean
probably occurred due to an error in /onlinetrade/jsp/controller.jsp line 53:
registerBean registerBeanInstance = new registerBean();
I know the javac is working, and a java file is created upon the JSP page, but the problem is -- the bean class files cannot be found!!!
Where should I create the package path and put my bean class file so that my JSP pages can pick them up?
Any help is greatly appreciated!
Thanks.

Can't access class files in jar file
I'm running Eclipse and trying to access class files in a jar file from source. I have added the jar file through Properties/Java Build Path/Add External JARs... but the class files are not visible from my source code. Any ideas what is happening?
Thanks!Depends what you mean by "visible." Are you getting a ClassNotFoundException? If so, your JAR isn't in your runtime CLASSPATH. You should be able to solve that (in Eclipse) by by modifying your project classpath.
If "visible" means your code is usng a ZIP class to peek inside the JAR & it's not working, best bet is to re-study the ZIP class Javadocs & examine the error messages carefully.
If this doesn't solve the problem, please provide more details & the specific error message/stack trace you're getting. -
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,
HPAll 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\

hello friends,
i'm trying to access a file using applets but i'm getting security error.
similar error for accessing the data base also so pls if you know help me how to access file/database using applets.You need to use a signed applet and know where the file is and in an accessable area; signing an applet will not allow you to go on a "fishing expedition" through the file system.

Conversion of class files to source codes
I was informed that it is possible to convert class files back to the java sourcs codes from where those are generated. How can I protect my source codes from illegal copying by others ?
hai ,
yes it is possible to convert class file into source code. there is a software called jad.exe available in the net
using witch u can convert class file into jar file. but i don't know how to protect the class file to avoid the illigal convertion. -

How do you specify class file for appletviewer?
List,
I have searched over dozens of posts for "NoClassDefFoundError" and "wrong name" as well as "appletviewer" and others. I have read many posts about people who have the same problem I do, but I still can't seem to find a remedy:
My machine is running Windows ME
My application runs fine stand-alone
(it's main() method sets up and runs the init() method it is intended to be an applet)
My classpath includes "." as well as the JDK directory and the full path to my applications jar file
All classes are part of the package iCalendar and jar'd in a file called iCalendar.jar
When I compile and run my app stand-alone I use the following:
javac ./iCalendar/ViewController.java
java iCalendar.ViewController
However I cannot get the application to run in either appletviewer or the browser. My applet tag is as follows:
<APPLET CODEBASE="." CODE="ViewController.class" ARCHIVE="iCalendar.jar" width=700 height=700>
I consistently get the message NoClassDefFoundError wrong name: iCalendar/ViewController
So if anyone could tell me what set up is need to get this app running in appletviewer/browser I would be greatly appreciative, I've been on this all day!
PatrickDrop one iCalendar out. The classpath should not
contain the path C:\JavaObjects\iCalendar.I did this, I also removed all duplicate copies of the .class files to make sure appletviewer only has the jar file to work with. My new CLASSPATH is:
.;C:\JavaObjects;C:\JavaObjects\iCalendar\iCalendar.jar
You should also decide whether to use the jar file or
not - that can cause problems with netscape -
weird problems.I definetely want to figure this out using the jar file, I want the entire jar downloaded to minimize trips to the server.
Try putting iCalendar.jar and iCalendar.html to
another directory and it should work - somehow
(probably because of the classpath or because
iCalendar.html is not where it should be) the
appletviewer is picking the class from outside the
jar.I created a directory off of the root C drive and called it temp, I copied the jar file and the html file to the temp directory and then tried appletviewer from the command line:
NoClassDefFoundError: ViewController (wrong name: iCalendar/ViewController)
Can this be because the jar file contains all of the class files whom all belong to the package iCalendar? Because to run it stand alone I must address iCalendar.ViewController, do I need to jar these files differently, and if so can I jar the directory structure?
Thanks again for the help, I have no clue at this point. -
How to access a file via Applet and JavaScript
I want to copy one file on the client machine from one place to another place from a Java Bean.
To do this I created an applet and a Java Bean as follows:
import java.applet.*;
public class FileUtils extends Applet {
public void copyFile(String src, String dest) {
private String source, destination; // setters/getters are there of course
public void copyFile(ActionEvent actionEvent) { // Bean
FacesContext fctx = FacesContext.getCurrentInstance();
ExtendedRenderKitService erks = Service.getRenderKitService(fctx, ExtendedRenderKitService.class);
String command = "var s = '"+ source +"'; var d ='" + destination +"'; " + " document.fileUtilsApplet.copyFile(s, d); ";
erks.addScript(fctx, command);
}Then I added the APPLET tag referencing the above class in the page fragment:
<f:verbatim>
<applet code="FileUtils.class" name="fileUtilsApplet" height="30"
archive="/context-root/Applet.jar"
width="200">
</applet>
</f:verbatim>From the Java console I can see the jar is successfully downloaded, but when the code in the bean is executed, the JavaScript code does not seem to do anything, as if the "copyFile" public method was not called at all and no output in the Java Console as well.
Note that I already followed the guidelines at http://www.oracle.com/technetwork/developer-tools/adf/learnmore/71-adf-to-applet-communication-307672.pdf .
Do you have any ideas?Ok, I can see the permission problem now:
java.security.AccessControlException: access denied (java.io.FilePermission c:\myfile.txt read)
at java.security.AccessControlContext.checkPermission(Unknown Source)
at java.security.AccessController.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkPermission(Unknown Source)
at java.lang.SecurityManager.checkRead(Unknown Source)
at java.io.FileInputStream.<init>(Unknown Source)
Edited by: user10047839 on 1-feb-2013 7.29
signing the Jar and downloading the certificate permanently does not change anything in Firefox. The Java console keeps giving the above exception.
Any idea? -

Getting JAR file for Applet doesn't work
Hi,
We have the following problem: we have some clients who want to use our applet. There are some clients that have problems with receiving the .jar file:
When the applet tries to start we get a ClassNotFoundException: 'prestaties.class' not found. (the client wants to acces the class file directly from the server)
If we check the .jar file, it exists on the client, but the file is empty.
What could be the problem?
- PRoxy or firewall blocks the jar file
- applet doesn't have enough rights to write.
Does anyone a solution, some workarounds or suggestions for this problem.
Thanks!
LukHi,
Thanks for answering my question!
Here is the extra information you asked.
At server side everything is OK (the jar file is present and has all the class files).
Where working with Weblogic server 4.51
The clients run JRE 1.3.0-C
I can't give you the applet code (confidential) but here is the html code:

<P><B>Voor het invullen van prestaties en vergoedingen heeft u de JRE 1.3 Java Plugin nodig: deze staat op de CD-ROM die u normaal gezien van de VDAB gekregen heeft.<br><br>
Ofwel kan u de plugin hier zelf downloaden (<U>opgelet:</U> bestand is 8 MB groot).<br><br>
U kan het VDAB callcenter contacteren om een CD-ROM aan te vragen of om problemen te melden. Het nummer vindt u onderaan het scherm.</B></p>
