I want to export may project (game) to different desktop platforms. I exported it from eclipse (on Windows) and I get JAR file. On my machine I can start it, but on other it won't work. I guess JRE is missing there.
So, I followed LibGDX instructions how to deploy on different platforms:
https://github.com/libgdx/libgdx/wiki/Deploying-your-application
But when I run that packr.jar app I get following output:
D:\packing>java -jar packr.jar windows.json
Output directory 'D:\packing\windows' exists, deleting
Unpacking JRE
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
copying resources
minimizing JRE
unpacking rt.jar
packing rt.jar
Done!
After that I really get my exe file, all together with jre dir, my original game jar file and some config.json file, but that exe file just won't run. No failure message, just won't run. Any idea what's going on here? Or maybe there is some other tool for packing jar files?
All I need is to make my game runnable on desktop platforms: Windows, Mac & Linux.
For windows OS you could use something like launch4j which simply puts a wrapper around your jar file.
It also has the capability to provide a given jre. So your users do not need to have one installed.
Ok, solved this.
So I've found out that if I run exe file from console (cmd) and redirect output to file I can have some error report regarding the run attempt. So I did that:
myapp.exe > log.txt
and get log this log file:
Loading JVM runtime library ...
Passing VM options ...
# -Xmx1G
Creating Java VM ...
Error occurred during initialization of VM
Unable to load ZIP library: D:\packing\windows\jre\bin\zip.dll
Zip file was there, but something was wrong with it so I replaced it with one I had in my Java installation (my was larger). After that I was able to run exe file well.

When I am compiling the Java code, I have written the command line shows the following:
C:\HTML>javac Jdbc.java
Jdbc.java:5: error: package com.mysql does not exist
Class.forName(com.mysql.jdbc.Driver);
^
1 error
I have installed XAMPP and started the Apache, MySQL and Tomcat and they are working. I have installed MySQL Connector which is platform independent and latest. I have copied the JAR executable file to the JDK folder. I have added the jar executable file path in the edit system environment variables,
''' Class.forName(com.mysql.jdbc.Driver);'''
If you reference classes from a library, you should add that library to the classpath (i.e. javac -cp .;path\to\your\mysql-connector.jar Jdbc.java). However, that would immediately result in a different error, because that code should be Class.forName("com.mysql.jdbc.Driver") (passing a String).
Some further remarks:
I have copied the JAR executable file to the JDK folder.
You should never manually copy files to the JDK folder (in older versions there was the ext mechanism, but this no longer exists in recent Java versions). In addition, MySQL Connector/J is a library, not an executable jar.
I have added the jar executable file path in the edit system environment variables
Java JARs do not belong on the PATH. In theory you can add them to CLASSPATH environment variable, but that is generally considered a bad idea: most ways of executing Java do not actually use it, and if it does get used, it can result in unexpected behaviour because of conflicting or unexpected libraries on the classpath, etc.
i have a MacBook Pro and have downloaded java version 1.8 and selenium also. But im unable to find JUnit. Can i get the command to check the location of my JUnit. I have tried using a code to check whether JUnit is installed and the output is successful.
JUnit is not part of the standard JDK content; same for selenium.
Thus: you have to do something to pull the JUnit jar to your system. Either by downloading it manually yourself; or by using a build system like Maven or Gradle that can take care about resolving "dependencies" and downloading required artifacts automatically for you.
But in order to locate jar files on your system, you can simply turn to find command, like:
find / -type f -name "*.jar"
which should list you JAR files existing in your file system. You can read here about this and other tools that help you find files in your file system using the command line.
created new cocos2d-x 3.6 project with cocos console comnand new -l cpp, all variables are set by running setup.py, then when i try to run cocos compile i get compilation errors.
log: log.txt
Cheked if there are spaces in paths but there isn't, everything is installed.
the problem is here

You can solve it by adding some lines to the SDK/tools/ant/build.xml

I tried building recutils version 1.7 downloaded from the home page, using the standard configure, make, sudo make install sequence, but when trying to run the resulting binaries. like recinf, I get the error:
recinf: error while loading shared libraries: librec.so.1: cannot open shared object file: No such file or directory
Does this mean I made a mistake during the build or is the package itself in error?
As Etan Reisner said the problem was that the shared object libraries were installed but not loaded into the cache, hence the need to run ldconfig. After running
sudo ldconfig
the binaries ran properly. If I had looked in /usr/local/lib, I would have seen the libs there.
I've been using Flashdevelop (version 4.4) for some time now with zero problems. I recently reinstalled Windows 7 however, and after installing Flashdevelop it is demanding Java 1.6 and won't compile without it. Let me be more specific, here is the error I get when I try to compile a simple HelloWorld-type test:
"Running process: C:\Program Files (x86)\FlashDevelop\Tools\fdbuild\fdbuild.exe "C:\Users\marc\Documents\DeleteMe\DeleteMe\DeleteMe.as3proj" -ipc 01be003c-6cb5-4d0b-9c35-c59dd2ea7a19 -version "4.6.0; 3.3" -compiler "C:\Program Files (x86)\FlashDevelop\Tools\flexsdk" -library "C:\Program Files (x86)\FlashDevelop\Library" -cp "C:\Program Files (x86)\Java\jdk1.6.0_34\bin" -cp "C:\Program Files (x86)\Java\jdk1.6.0_34"

The GlobalClasspath setting for the Java 1.6 JDK is set to: C:\Program Files (x86)\Java\jdk1.6.0_34\bin
I have also set my JAVA_HOME environment variable to the same location as well. Might I be neglecting to set another environment variable?
JAVA_HOME should be
C:\Program Files (x86)\Java\jdk1.6.0_34
and not
C:\Program Files (x86)\Java\jdk1.6.0_34\bin
FlashDevelop currently doesn't support that your JAVA_HOME environment var contains several paths (C:\Program Files (x86)\Java\jdk1.6.0_34\bin\java.exe, \bin\java.exe).
Modify it to only indicate the first path (C:\Program Files (x86)\Java\jdk1.6.0_34\bin\java.exe).
As someone who was dealing with this, I just found an answer that doesn't involve mucking with the PATH variables.
Go into your Flex SDK, /bin directory, look for the JVM config file conveniently named jvm.config
Inside, there is a param 'java.home' which, if left empty, will cause it to search for it's own value. Enter in the main path to the JRE - in my case,
java.home=C:\Program Files\Java\jre1.6.0_07\
I found mine by going to "Control Panel > Java > Java tab > View... button" to see all the installed versions and their paths
I prefer this method because I feel like you shouldn't have to modify settings on your whole system to get 1 program to work, if you have the option instead to just modify that program's settings.
jvm.config in C:\Program Files (x86)\FlashDevelop\Tools\flexsdk\bin\jvm.config is much more better than path variable.
Please avoid Path variable.
In jvm.config just set jre URL directory
java.home=C:\Program Files\Java\jre1.6.0_07
May be you update the Java, last version of Java ask you to delete older version. Then go into the file
C:\Program Files (x86)\FlashDevelop\Tools\flexsdk\bin\jvm.config
and replace
java.home=C:\Program Files\Java\jre1.6.0_07\
by the folder were is your new version
java.home=C:\Program Files (x86)\Java\jre1.8.0_25\
