Web server cannot access .jar file?

Hi all,
I'm using NetBeans 4.1 IDE with the bundled Tomcat 5.5.7 on Windows XP sp2.
I have a .jar file which I must make available for the web server (not only for my web app). So I did the following:
Added a CLASSPATH variable to the user environment (pointing to my .jar file),
Shutdown Tomcat,
Restarted the IDE (because it is responsible for launching Tomcat, so Tomcat inherits its environment vairables from the IDE),
and finally ran my web-app.
The result: the web app could not find classes from the .jar file.
However, if I copy the .jar to the server's common/lib directory, everything's ok!
Why? I'm sure I don't have to put .jars in common/lib in order to make them visible by the server! I've read that adding them to the CLASSPATH is just as good solution... what is going on?

Tomcat has its own ideas about classpath. In particular it ignores the system classpath, so that each web application can have its own seperate one.
Jar files should normally live in the /WEB-INF/lib directory of your application.
If you want to share them across multiple apps, use the /shared/lib directory.
/common/lib should not normally be used except for database drivers when using tomcats JNDI datasources.

Server 2012 R2 SMB - The process cannot access the file '\\server\share\test.txt' because it is being used by another process.

Hi,
We are having issues with Server 2012 R2 SMB shares.
We try to write some changes to a file, but we first create a temporary backup in case the write fails. After the backup is created we write the changes to the file and then we get an error:
The process cannot access the file '\\server\share\test.txt' because it is being used by another process.
It looks like the backup process keeps the original file in use.
The problem doesn't always occur the first time, but almost everytime after 2 or 3 changes. I have provided some code below to reproduce the problem, you can run this in a loop to reproduce.
The problem is that once the error arises, the file remains 'in use' for a while, so you cannot retry but have to wait at least several minutes.
I've already used Process Explorer to analyze, but there are no open file handles.
To reproduce the problem: create two Server 2012 R2 machines and run the below code from one server accessing an SMB share on the other server.
Below is the code I use for testing, if you reproduce the scenario, I'm sure you get the same error.
We are not looking for an alternative way to solve this, but wonder if this is a bug that needs to be reported?
Anybody seen this behavior before or know what's causing it?
The code:
string file =
@"\\server\share\test.txt";
if (File.Exists(file))
File.Copy(file, file +
".bak", true);
File.WriteAllText(file,
"Testje",
Encoding.UTF8);
The error:
System.IO.IOException: The process cannot access the file '\\server\share\test.txt' because it is being used by another process.

Microsoft Excel cannot access the file "-". There are several possible reasons. Windows Server 2008 R2 with Microsoft Office 2010

I have a problem with starting the Excel Application under a particular user (service account).
I try to schedule this C# script through an application X (not Windows Task Scheduler. And this
application will always use a service account to run services on the server). If I run the C# script in
command prompt under the same user, it runs. Under the application X, which uses the exact same
user, to initiate the C# script, it fails to open the Excel application (not sufficient permission?).
This script calls application.Workbooks.Open(<ExcelFileName>,0,false,Type.missing....). At this line
of code, it gives the following error:
Microsoft Excel cannot access the file "...". There are several possible reasons:
-The file name or path does not exist.
-The file is being used by another program.
-The workbook you are trying to save has the same name as a currently open workbook.
I tried all the methods that I found online as follow:
Create directory "C:\Windows\SysWOW64\config\systemprofile\Desktop" (for 64 bit Windows) or "C:\Windows\System32\config\systemprofile\Desktop" (for 32 bit Windows).
Changed the DCOM config for the Microsoft Excel application to include this user for Local/Remote Launch and Access.
Enabled all macros in Excel application and set the Trust Center.
Add the user to have full control on all folders that contain the Excel file.
Under DCOM
config, Microsoft Excel Application, if I modify the Identity tab to check on "This User" and enter the username/password to let Excel always run under that user. Then the application runs perfectly. However, other users can't run the excel application
on their own with the following error: "Cannot use object linking and embedding". If I check "Use the launching user", then Excel can't be launched. No errors in the logs or events anywhere to check.
Yet, still the same error. I think it's permission but I am not sure where and what to do for this to work.
Now, normally, when I run this excel report, I can double-click on the file and it'd automatically run,
save the new parameters into the current file and generate a new excel file (with date attached to the
file name). That means there is a change (save) to the original file.
Environment: Windows Server 2008 R2 and running Microsoft Excel 2010.
I appreciate all your help!

I am wondering if this has anything to do with having the user log into Excel.
In point #5 above: Under DCOM config, Microsoft Excel Application, if I modify the Identity tab to check on "This User" and enter the username/password to let Excel always run under that user. Then the application runs perfectly. However, other
users can't run the excel application on their own with the following error: "Cannot use object linking and embedding". If I check "Use the launching user", then Excel can't be launched. No errors in the logs or events anywhere to check.
Because running with the launching user proposes an user to run the Excel application. However, I do not think there is any where that we can pass in the password for this user to Excel. However, this Excel has all the permissions to Excel application as
well as the folders that have the Excel files.
Please help!
Thank you!

Crashes when running applications from network share - "Windows cannot access the file for one of the following reasons"

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.

Hi,
>>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.
Best Regards.

The process cannot access the file during Crystal Report export

We are exporting crystal reports into PDF using ExportToHttpResponse (code snippet below)
      // Getting the type of the report file which has been selected by the user. (which will be REPORT CLASS type)

A bit of a confusion on my part;
Now we have created these REPORTS using Basic Crystal Report 10.5, which comes bundled with Visual Studio 2008 and .Net Framework 3.0. Now on our machines, we have never experienced any issues.
Going by the above, you should have references to CR assemblies of version 10.5.3700 only. No other references.
Now, looking at this paragraph:
BUT on the DEV server (web server) which has .net Framework 3.0 and in its GAC its has CRYSTAL DLLs version 11.5 (required to create an Object of ReportClass and its related functions) ; sometimes we get the following error while exporting crystal report to pdf:
I wonder what runtime was deployed to the server. E.g.; if you are using CR 10.5, your assemblies will be 10.5.3700 and you should be deploying the following runtime (depending on 32 bit / 64 bit, etc.):

"The process cannot access the file ..." occurs when export crystal report

We are using a web application developed in VS 2005, .NET 2.0 with the bundled Crystal Reports version 10.2.3600.0 running on a Windows 2003 Standard server with 4GB Ram and Dual CPU's. Periodically we are still receiving the following error in our production environment:
InnerException:
The process cannot access the file because it is being used by another process.
   at CrystalDecisions.ReportAppServer.Controllers.ReportSourceClass.Export(ExportOptions pExportOptions, RequestContext pRequestContext)
   at CrystalDecisions.ReportSource.EromReportSourceBase.ExportToStream(ExportRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.FormatEngine.ExportToStream(ExportRequestContext reqContext)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.ExportToStream(ExportOptions options)
   at CrystalDecisions.CrystalReports.Engine.ReportDocument.ExportToStream(ExportFormatType formatType)
This is occuring at the point on the code where the report is being exported to a PDF. Exporting the report to Excel does not appear to cause the error.
                Stream outStream = report.ExportToStream(ExportFormatType.PortableDocFormat);
                byte[] charStream = new byte[outStream.Length];
                outStream.Read(charStream, 0, (int)outStream.Length);
                if ((charStream != null) && (charStream.Length > 0))
                    HttpContext.Current.Response.ContentType = "application/pdf";
                    HttpContext.Current.Response.OutputStream.Write(charStream, 0, charStream.Length);
                    HttpContext.Current.Response.End();
            report.Close();
            report.Dispose();
            ds.Dispose();
            GC.Collect();
Closing and disposing of the report and dataset (xsd) are followed by a call for garbage collection. We are unable to produce the error in our development environmennt and have not at this point been unable to pinpoint a problematic report. The development team members do have SP1 installed. The report limit has not been changed from the standard of 75 jobs. Reviewed the following document, Re: "The process cannot access the file ..." occurs when export crystal report However this applies to VS 2008. Any suggestions to resolve the issue would be greatly appreciated.
Thanks,
Joe

To answer your questions:
Is it correct to presume that the physical number of CPU's is not factored into the CPL? So that a Server with 2 or more processors does not increase the 3 concurrent requests? Therefore 2 CPU's would not increase the CPL limit to 6 processes?
- Server with 2 or more processors does not increase the 3 concurrent requests.
What would be an alternate solution to this limit be, considering the report requests could increase significantly?
- Only way around this would be to web farm the solution
If only only 3 reports can be processed at the same time. If one or more of the reports currently processing is taking longer due to receiving large amounts of data, how does that affect the queue? And what is stored in the queue, data and/or the report? Is this something that could consume memory?
- The report can take as much time as it needs. The result is that one license will not be released until the report is done. There is no data stored, just a pointer to the report. However queued apps will chew up memory, some times to the point of the server becoming unresponsive
I have read in the documentation on this site, that the dataset sent to the engine is copied in memory during report construction. So if a large amount of data is requested for a report (as an example 10+ MB) Could enough users requesting reports drive the memory up because memory usage doubled due to the dataset?
- Absolutely. See [Crystal Reports Guide to ADO.NET|http://www.sdn.sap.com/irj/boc/index?rid=/library/uuid/401c4455-a31d-2b10-ae96-fa57af5aec20].
Understanding the the CR DLL's are loaded on the first report request, do they get released at some point time due to inactivity or garbage collection? How much memory usage could be consumed when they load and stay resident?
- No they do not. Not as long as the application is running.

How to access jar files

Hello,
I've created a web application using servlets and jsp.
Under Tomcat/webapps dir, I created my project dir and copied jsp files there, whereas copied all the java and class files under webapps/projectdir/WEB-INF/classes/mypackage. I also created a web.xml file under WEB-INF dir with my servlets mapping. I aslo created a lib dir under WEB-INF and copied jstl.jar and standard.jar in there. So far my application runs fine.
Now I've to include some jar files that will be providing data from the backend to my servlet. I can't have .class files instead of .jar files, that is the restriction the way the backend files are built.
Can anyone tell me how to make Tomcat access those jar files.
Thanks.

Ok then. I think the page you should read is [Tomcat 5 classloader documentation|http://tomcat.apache.org/tomcat-5.5-doc/class-loader-howto.html], though they simplified the structure in [Tomcat 6|http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html].
Normally the classpath of a web application is restricted to
- WEB-INF/classes directory
- jar files in WEB-INF/lib
- jar files in the server /lib directory.
So if you have a common library that is used by multiple web applications, you could give each web-app their own individual copy of that library in WEB-INF/lib, or you could have them all use the same one in the server lib directory. There are pros and cons to both approaches.

a) multiple instances of the LV development environment are running (this is possible in windows XP for instance when "switch users" is allowed and each user launches LV)
b) multiple compiled LV executables are run by the same user
c) any mixture of the two above
I have an application case when either of the three above would be a very good solution, was not for the problem encountered. Say, b): the user is given two deployed executables, and can decide to run either or both concurrently. Moreover, I want these applications to be visible on the web, so they are compiled with the webserver turned on, default settings.
The problem I've seen (LV8.5.1, winXp for sure, but I think I've seen it as well in linux and other versions as well) is that each new instance of the LV engine tries to get hold of the tcp port (default 80), so that all instances beyond the first complain about "The Web Server cannot start. Is the Web Server port already in use?"
While I can understand the origin of the message, and found some posts on the forums somehow related to it, I don't like it too much.
I could think only of two workarounds here: 1) set different web server ports for each LV instance, and instruct the remote users to direct their browsers to a webserverort link to access each VI; 2) run all the applications from the same instance of the LV dev system. The latter is not so convenient for me, due to conflicts in global VIs between all instances of the applications [compiling executables IS a way to privatize memory spaces in this case, AND global variables are imho well justified for the fairly complex application I have in mind here].
Is there a third, more elegant solution perhaps, which I'm missing?
Thanks, Enrico

What is it in particular that you dislike about the message?
How would you like LabVIEW to behave in this case?
No problem with the message, but I'd just be very happy if a single
web server would serve all my instances of the executables on the same
port. I.e., if 2.exe is open and wants to start another server on the
same port used already by 1.exe, then 2.exe becomes served by the
server already opened. Am I demanding too much? Am I missing some
necessary logic?
At the moment, anyway, I'm stuck with the vi being served correctly,
but not the compiled application, and I can't figure out why. It's
LV8.5.1, and yes, I have in the .ini

Do you have antiVirus installed on the sharepoint servers?
These folders may have to be excluded from antivirus scanning when you use file-level antivirus software in SharePoint. If these folders are not excluded, you may see unexpected behavior. For example, you may receive "access denied" error messages when files
are uploaded.
Please follow this KB and exclude the folders from Scanning.

Excel Automation with Interop - Windows Service - Microsoft Excel cannot access the file

I have a windows console application, which automates Excel. In our scenario the application gets called from a Windows Service. If the console app is executed directly everything works fine. If the console app is executed through the Win Service, we get
the following error when trying to open the excel file:
Unhandled exception Occured : 'Microsoft Excel cannot access the file 'bla.xls'. There are several possible reasons:
The file name or path does not exist.
The file is being used by another program.
The workbook you are trying to save has the same name as a currently open workbook.'.'
The code snippet used to open the file:
xlApp = new Application();xlApp.Visible = false;xlApp.UserControl = false;xlApp.Application.ScreenUpdating = false;xlApp.DisplayAlerts = false;xlWorkbook = xlApp.Workbooks.Open( Filename: filePath, UpdateLinks: 2, IgnoreReadOnlyRecommended: true, Editable: false);
The console app and windows service are running on a Win Server 2008 64-bit OS with Excel 2013 32-bit installed. The service is running with a special user account, which has all the right permissions on accessed files and folders. The excel process is also
started with the same account (I cheched that one).
I already tried to do the following, but to no avail:
Run excel.exe /automation -> worked fine
Created the folders and also gave full control to the account under which the service is run (even gave full control to Everyone)
C:\Windows\SysWOW64\config\systemprofile\Desktop
C:\Windows\System32\config\systemprofile\Desktop
Configured DCOM
Excel Application -> Identity -> Specific user account
Excel Application -> Identity -> Interactive User
Excel Application -> Security -> Launch permissions -> Everyone full control
Several combinations of the above
So I really am stuck with this problem right now. Any input on this is appreciated.

Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office
may exhibit unstable behavior and/or deadlock when Office is run in this environment.
If you are building a solution that runs in a server-side context, you should try to use components that have been made safe for unattended execution. Or, you should try to find alternatives that allow at least part of the code to run client-side.
If you use an Office application from a server-side solution, the application will lack many of the necessary capabilities to run successfully. Additionally, you will be taking risks with the stability of your overall solution.
You can read more about that in the
Considerations for server-side Automation of Office article.

Recurrent error in Win32 install logs (The process cannot access the file..

can use the products but this shouldn't be fine... do I have to stop a service or grant some permission ? any help is appreciated.
thanks & regards,

not having any JAVA_HOME env var. Did some checkings and :
- one machine was having Java libraries because of DB2
- the other machine was a fresh Win2003SP1 with SQL Server 2005
guess can set JAVA_HOME to C:\Hyperion\common\JRE\Sun\1.5.0 before installing Essbase, but also guess it's a documented/automatic step... wonder what I'm missing ?
doing the most basic-mode installations (defaults, automatic deployments), once I get them clean will perform more sophisticated ones. Searched the 9.3.1 doc PDFs without useful findings.

Backup stopped before completing. The process cannot access the file because it is being used by another process

I am working with a client who is attempting to backup to a NAS device
The device is a linksys NSS6000 (Cisco device).
It’s a dual 1Gbit LAN device that supports CIFS / FTP and NFS transfers. It has only 1Gbit lan connected.
The device has 4 * 500 gb sata drives in raid 1 attached.
Cables go from cat 5 to fiber back to cat5. (The NAS is located at a neighboring office) The switches are 1gbit.
Server is a win2k8r1 fully up to date.
When backing up to the NAS device, the following error occurs:
Running backup of volume Local Disk(D:), copied (86%).
Running backup of volume Local Disk(D:), copied (90%).
Running backup of volume Local Disk(D:), copied (94%).
Running backup of volume Local Disk(D:), copied (98%).
Backup of volume Local Disk(D:) completed successfully.
Backup stopped before completing.
Summary of backup:
Backup stopped before completing.
The process cannot access the file because it is being used by another process.
If we redirect the backup to a folder on a 2008 share, the backup completes successfully.
Only when backing up to the linksys NSS6000 does the error occur.
No other backup processes are writing to the NAS device so I can't understand why the process thinks the file is
being used by another process.
One thing we did notice that when the backup to the NAS device occurs, throughput is about 150 mbit average
On the 2008 server shares we successfully backup to, the through put is 500 mbit. Not sure if that is important, but
might be worth mentioning.
The following event log entry was noted at the end of the backup.
The description for Event ID '519' in Source 'Microsoft-Windows-Backup' cannot be found.
The local computer may not have the necessary registry information or message DLL files to display the message,
or you may not have permission to access them. The following information is part of the
event:'2009-05-12T10:13:31.617Z', '', '2147942432', '%%2147942432'
Any ideas?
Thanks..Michael

I am also seeing the same problem backing up nightly to a brand new NAS device (WD My Book Live)
All the error codes are the same as those in this thread.
From Windows Event Viewer:
The backup operation that started at '‎2011‎-‎03‎-‎25T06:00:19.811302700Z' has failed with following error code '2147942432' (The process cannot access the file because it is being used by another process.). Please review the event details
for a solution, and then rerun the backup operation once the issue is resolved.

How do I fix this error: DF024: Unable to preserve original file at ... Error 32 The process cannot access the file because it is being used by another process.(Seq 1352). ?

I am installing creative the cloud Illustrator desktop app on a machine with windows 7 64 bit running in a domain environment. The download starts and takes about runs for a bout 10 minutes and then stops with the error: DF024: Unable to preserve original file at "C:\Program Files\Adobe\Adobe Illustrator CC 2014\Support Files\Contents\Windows\AdobeLinguistic.dll" Error 32 The process cannot access the file because it is being used by another process.(Seq 1352)
I am logged in as a network administrator and there are no other apps except a web browser (Chrome) running. There are no other users logged into the machine.
How can I see what other process is using the needed file so that I can fix it?
Thanks

MelissaB34 it looks like you already are reviewing your installation log files but you can find more information at Troubleshoot install issues with log files | CC - http://helpx.adobe.com/creative-cloud/kb/troubleshoot-install-logs-cc.html. From the error you have posted it appears that your current User account is either unable to update C:\Program Files\Adobe\Adobe Illustrator CC 2014\Support Files\Contents\Windows\AdobeLinguistic.dll or does not have sufficient file permissions to do so. Since you mentioned you are on a domain please ensure that you are working with your I.T. department and have correct access to this directory.
You may want to also consider logging in under a local administrator account to see if you face the same difficulties. This would help you determine if you are facing a file corruption issue or file permission issue.

The process cannot access the file because it is being used by another process with Execute package task

Hi,
I've a master package that calls other packages with an Execute Package Task. Sometimes we have an error: "The process cannot access the file because it is being used by another process" and sometimes not. It seems random.
We are working on a Terminal Server and the SQL Server database engine and the files are placed on another server. It seems that the errors doesn't occu when we run the packages on the server with a job. We can't log onto the windows server on this machine..
Hennie

I've seen this myself. On most occasions an immediate rerun would fix the issue. As stated this happens only when we try to run this from BIDs. From SQL agent job it always runs fine.
