I have an apache-tomcat (8.5.35) that runs a web app. It runs on different computers (Windows 10, Mac OS X) without a problem but won't work on a specific computer (also Windows 10). I am not really sure why and have spent hours trying to find out why it won't work. The log files display
org.apache.catalina.loader.WebappClassLoaderBase.clearReferenceJdbc The web application [web-app] registered the JDBC driver [org.postgresql.Driver] but failed to unregister it whenthe web application was stopped. To prevent a memory leak, the JDBC has been forcibly unregistered.
Any idea why it won't work with this specific computer? I have postgresql 10 (x86) installed in this computer. I thought Kaspersky would have been an issue so I disabled it and uninstalled both the Small Office Security and Secure Connection but the problem seems to be linked into Windows or something.
I also tried different versions of tomcat, postgresql, and jdbc drivers (postgresql jar files).

Can I install Visual Studio Code on Windows server 2008 ?
I am a developer but I sent the information to my administrators and they told me that the setup file crashes after launched
I get seput file from hee https://code.visualstudio.com/download
procesor: Intel(R) Xeon(R) Gold 6142 CPU # 2.60Ghz - 2.59 GHz
RAM: 8 GB
64-bit
virtual machine
1 CPU - 2 cores
Windows Server 2008
First time answering here so bare with my vintage reply formatting. (also pardon that i couldn't capture screen due to server is on a intranet that not accessible on this device causing a long reply)
Being a unfortunate fellow that need to work on legacy Systems and Application frequently, i happen to have a fresh 2008R2 server recently setup by my team's Server Admin with following specs:
processor: Intel(R) Xeon(R) Gold 5220 CPU # 2.20Ghz - 2.19 GHz ,
OS: Windows Server 2008R2 x64 ,
RAM: 8GB
The versions that is able to install was 1.70.3,which is the same version that is the last supporting versions for Windows 7 as well,if you happen to need to work on devices using that OS version.
although i'm uncertain whether it is a VM or not, i'd like to point out a few more things that your question did not cover but need to consider:
The installer version (System setup vs User Setup)
aside from the x64 |x86 | ARM installer differences, as you've not mentioned which versions of the build and which exact setup installer you sent to your admin, i've first replied which build version successfully installed on 2008R2, which as of writing the latest build was 1.73.0 and on run,it pop up a error message as follow regardless of System/User Setup:
This Program does not support the version of windows your computer is running.
in our current case that we want specific previous versions installer, VScode FAQ on previous versions have a URL lists that enables you to download a specific build version of your preferred setup. For my case (and also refer below to exactly why this one), i've go for System setup, and i know the aprox. supporting version was ~1.70.0, so i used the link as below and replace the {version} to start:
https://update.code.visualstudio.com/{version}/win32-x64/stable
Active Domain, Multiple user sessions etc.
Per VSCode requirements page stated,
VS Code does not support multiple simultaneous users using the software on the same machine, including shared virtual desktop
infrastructure machines or a pooled Windows/Linux Virtual Desktop host
pool.
as im not sure do you work solo or do have fellow colleagues to code on the server at the same time, you might need to reconsider to install using user or System setup.
if your intentions are to use exclusively on a specific AD account, then user setup should probably be good enough.
however, if the intentions was to setup say a shared Remote desktop connections on the VM that allows multiple RDC sessions simultaneously for coding,programming etc., so you intend to install a system setup to allow all users on said server to be able to use VScode, then you might run into the problem the VScode requirements stated it does not support.
in addition, as i was remote connected as administrator , when using a 1.70.2 user setup ,a different warning message as follow was thrown:
This user Installer is not meant to be run as Administrator. If you would like to install VS Code for all users in this system, download the system Installer instead.Are you sure you want to continue?
as the installer itself also checks with the operator on this matter, your admin may have skipped on the exact reasons why the install failed and just told you the installer crashed.
if you absolutely need VScode to run on the server but can't install for reasons, the last resort (aside from going for alternatives like notepad++) is to Setup a Portable Mode builds on your own workstation/devices first, then upload the package to the server and use it from there.
i wouldn't go into too much detail in that as this reply already span for a starwars trilogy length but keep in mind, version limitations still apply, and whatever add-ons you need, you need to download them first before bundle it into the package to upload and run on your server.
Anyone that is a System admin or infrastructure architects , do correct me on my novice understanding on Server settings etc. as although i'm primarily a programmer, i did end up touching a lot more things that i'm not specialized into over the few years of vendor career work so there bound to be incorrect/inaccurate concepts i spilled. cheers.
I've recently downloaded Oracle SQL Developer 4.1.3 from Oracle Website
and this with JDK as well, but I tried to run in windows 10, it only goes 10% of progress bar, then disappeared. Can't run it at all?
SQL Developer 4.1.3 can connect to Oracle 11g db, right?
I've found 2 things most likely cause what you're experiencing:
video driver conflict with windows and Java - this is usually what happens to cause the program to just 'disappear.' If you open a CMD window, CD to your sqldeveloper\bin directory, and run the exe from there, you should see some sort of Java 'crash' stack when the GUI goes away suddenly. And in there, you'll see a reference to a windows dll that belongs to the video driver. if that's the case, update that driver, and you should be good
the application settings for your OS user are corrupted. To fix, find your AppData, Roaming Profiles folder for 'SQL Developer' - there should be a system4.1.3... folder in there - rename it, and restart sql developer.
I'm stumped. On my old Mac, Jconsole couldn't connect to local JVMs. I thought I had done something to mess up system configuration. Then I got a new Mac. The first thing I did was download a jdk, install it and check to see if jconsole could connect. It could.
Then I pulled over users and applications from my old mac using my Time Machine backup drive except my system files. Still worked.
But I found that odd things were happening with my development environment. In eclipse, I could start my Jboss server, but eclipse never recognised that the Jboss server had started. So, I could never add or delete war files to it through eclipse.
Also, the jboss instance could not connect to my localhost PostGres database even though the ds file clearly gave localhost as the host to connect to.
I fixed these problems by giving my new Mac the hostname the old Mac had had.
But now I am back to not being able to connect to my local JVMs through jconsole.
This affects not just jconsole, but jprof as well so I'd like to get it fixed.
jconsole can see the JVM processes. It just times out when I try to connect.
I also tried connecting to localhost: by writing a java class that slept for five minutes and running it with the following command line:
java -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010 -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.authenticate=false
but I cannot connect to localhost:9010 or :9010 either.
My guess would be this is some network configuration problem, but any help would be really really appreciated.
Thanks,
George
I had similar issues with timeouts. Looking at the packets being sent, it seems that jconsole was trying to connect via an external interface and being blocked by the firewall.
I added
JAVA_TOOL_OPTIONS=-Djava.rmi.server.hostname=localhost
to my environment to ensure all java processes used localhost instead of an external interface for RMI (which is what jconsole is using for connections)
We have a large application that has been developed over 15 years and in installed in 200+ client locations. The application currently consists of an Access database and a bunch of executable and report files located on a network share. A Setup.EXE file is run on each client machine (dlls are installed on the client) and then the client machines run the executables directly from the network share. During our upgrade procedure the new executable and report files are copied to the network share and that way each client gets the update immediately.
Our current installation program is very old and, among other things, it doesn't handle x64 so we are in the process of moving to a new deployment tool. At the same time we are migrating client Access databases to SQL Server. I am having difficulty finding a deployment tool to do what we require. Specifically we need the install/upgrade file to do the following:
It must be able to be run from a client machine on a network and copy the new executable and report files to the network share. That share could be a Linux box or a dumb storage device.
Accept a password before running the installation
Allow the user to select the network share as the location to copy the executables
It must NOT add anything to the client machine from where the package is run (Add/Remove Programs, registry, etc.)
Connect to a SQL Server database and run a script
The install/upgrade must be contained in a single, standalone .msi or .exe file. (no dependencies on dlls or frameworks other than those that come with Windows XP)
The file must be able to be run in one simple step. It is the end user that runs the upgrade without our support and without involvement from IT.
It looks like the closest thing to what I need is WiX but the problem there is that whenever the .msi file is run from a client, the client machine thinks that a program is being installed so it allows the client machine to uninstall the product, which is not acceptable.
If the product were written today it would certainly be architected differently but it currently is what it is and we can’t change that. Any help here would be greatly appreciated!
WiX is just a toolset built on top of Windows Installer technology. It makes many things easier and simpler as well as hides lots of Windows Installer weird features... But, it is still limited by Windows Installer, its underlying technology.
Your list of requirements made me think that Windows Installer is not the right technology to choose. I would assume that you'll spend more time on workarounds, than on functional code... But I have no experience with other installation technologies, so I'll leave those recommendations to others.
I'm trying to install PGSQL 8.3 (and 8.4 and 9.0) on my work laptop. At the end of the installation, the installer complains it can't init the cluster. Investigating more, I noticed that the service is not even installed. I did use the "OneClick Installer", not the pgAdmin stand alone install. I tried installing as Administrator and as a regular user. In all the cases, the pgsql system account is created and the files copied, but the service is not.
I successfully installed PGSQL many times on my home PC. Both the laptop and desktop use Windows 7 64 bits (former is Professional, later is Ultimate). The only differences I can think of are that the laptop is part of an Active Directory and uses McAfee, while the desktop is only on a workgroup and uses Windows Security Essentials.
Are you sure the postgres user is allowed to create files in the data directory? The installer defaults to putting the data directory where the binaries are installed (e.g. c:\Program Files) which is usually not writeable by a regular user (and I never understood why the installer contains such an idiotic default).
McAffee could be an issue though. I have heard several stories about virus scanners infering with the Postgres (or other DBMS). Can you turn McAffee off - at least for the data directory?
Another problem could be that the installer is not able to create the postgres windows user (that is used to run the service).
If you are a local administrator on that machine, try to create the user before the installer does it. The installer will then not try to create the user account.
As a last ressort, you could install PostgreSQL without the installer (this is what I usually do).
Download the ZIP file from http://www.enterprisedb.com/products-services-training/pgbindownload
Unzip it into a convenient location
Run initdb (make sure you do that using the postgres user account - the one that is used to run the service later!)
run pg_ctlr register to create the Windows service
If any of those steps fails you'll see a proper error message which is not always the case with the installer.
Anti-virus is a well known issue:

PostgreSQL connection problems
(answer is from one the core developers)
Postgresql 8.4 and BitDefender 11
With earlier versions of PostgreSQL, I found I had to delete the user "postgres" before reinstalling would work. Not sure what versions had that problem, though.
