install4j fails to access JRE on remote service

Executing the installation program for a 64-bit Windows client, I'm confronted with a failure when a required JRE is missing and I choose to let it download the JRE from a remote service (which the client, when installed, will communicate with).
My install4j version is 7.0.12 (build 7368).
The install program is configured to bundle with the JRE labelled "Windows (amd64) 12.0.1".
I selected "Dynamic bundle" and an HTTP download from "${compiler:sys.publisherUrl}/jres/windows-amd64-12.0.1.tar.gz".
At the end of the build process, install4j tells me to
make sure that the file
C:\Users\ME.install4j7\jres\windows-amd64-12.0.1.tar.gz can be
downloaded from
https://www.NN.de/jres/windows-amd64-12.0.1.tar.gz
I followed this instruction and to confirm that I did it correctly, I entered https://www.NN.de/jres/windows-amd64-12.0.1.tar.gz in a browser and found that I could download the archive successfully.
When I run the installer, it doesn't find a suitable JRE, offers to download the JRE and tries to get it, but its attempts aren't successful: after a while it times out and then shows an error dialog, informing me about a problem and asking me to check my internet connection and try again. It also points me to a log file, which says
[0:368] Searching for a JVM

[0:393] Search sequence finished
[0:394] ERROR: No JVM found
[0:395] Download location: https://www.NN.de/jres/windows-amd64-12.0.1.tar.gz

(...)
[15:805] ERROR: HttpQueryInfo (try 20) failed with error code 12150

My questions are obvious:
What can cause this error? What does "error code 12150" mean? Can a firewall be blocking the request?
What can I do?

OpenSUSE 13.1 java jar exception : java.awt.HeadlessException : No X11 DISPLAY variable was set

I have a runnable java jar which is working fine in Windows. The same jar I am trying to run on OpenSUSE 13.1 but it throws the
java.awt.HeadlessException : No X11 DISPLAY variable was set, but this program performed an operation which requires it.
I tried almost all possible options (like export $DISPLAY=:0 and so on) available on Google and StackOverFlow but still with the exception.
Below are the OS-Release details :
NAME=openSUSE;
VERSION="13.1 (Bottle)";
VERSION_ID="13.1";
PRETTY_NAME="openSUSE 13.1 (Bottle) (x86_64)";
ID=opensuse;
ANSI_COLOR="0;32";
CPE_NAME="cpe:/o:opensuse:opensuse:13.1";
BUG_REPORT_URL="https://bugs.opensuse.org";

Even small help is appreciated.

I am using Windows 7
I re-installed OS also..
Please find snap shots of error message.
error popup message as shown in snapshot 1
I'm getting below error when i try to run my application
Exception in thread "VFW Request Thread" java.lang.UnsatisfiedLinkError: JMFSecurityManager: java.lang.UnsatisfiedLinkError: no jmvfw in java.library.path

solution for above Problem..
JMF Studio is 32 bit supporting software so we must install 32bit supported JDK and also Eclipse then we not get any exceptions and errors.
Once Run your application then Automatically Your system webcam will "On".

JMF Studio is 32 bit it not support to 64bit OS/Eclipse,
and another reason is may be Environment variable not defined.

Playscape publishing kir (1.17) error: Failed to execture lib2dex

We have problem with PlayscapeSDK 1.17.411 in our Unity Android project.
When we build the game, on "Publishing kit post-process" step we have this error:
An error occured while applying post-build logic: Failed to execture lib2dex. Error description: jar2dex.
PlayscapeSDK we add in project according to official instruction.
We build project on OS Windows7 x64.
System variables ANDROID_HOME, JAVA_HOME, JDK_HOME added.
Also path to JAVA exist in PATH variable.
Google Play Service lib(google-play-services.jar) we stripped (3,79 MB)
Using soft:
Playscape sdk 1.17.411
Unity 5.3.2f1
JDK jdk1.8.0_71
By the way, the same error we have, when try to build app on MacOS (El Capitan)

unknown sqlite error - java mac os 10.5 - unsatisfied link error

I just recently started getting this error for a completely unknown reason.
The code has not changed since last run time.
Any ideas?
java.lang.UnsatisfiedLinkError: /private/var/folders/l8/l8xdyr88GEO5adGKtmu9XU+++TI/-Tmp-/sqlite-3.7.2-libsqlitejdbc.jnilib: no suitable image found. Did find: /private/var/folders/l8/l8xdyr88GEO5adGKtmu9XU+++TI/-Tmp-/sqlite-3.7.2-libsqlitejdbc.jnilib: unknown required load command 0x80000022
update on root cause:
java.sql.Connection conn = DriverManager.getConnection(mySQL);
where mySQL = "jdbc:sqlite:/Users/Jason/seeking.db"
This file 100% exists. This connection attempt is causing the error.
//////////////SOLUTION:
I had switched my java (Mac system preferences for java) preference to load Java SE 6 as a priority. This will not work with the SQLite jdbc library.
J2SE 5.0 is needed for this library to behave properly (it seems).
Hope this helps someone else down the road!!
