Issues with launch4j
Mar 10, 2021 Launch4j is a software utility that allows users to wrap Java applications into Windows native executable programs. We all know how tiresome it can get to open a Java-based application on Windows. Apr 18, 2013 Convert JAR to EXE using Launch4J (Tutorial) Click on new Configuration menu. When a popup window appears saying discard changes, click on yes; Now Select the path to your output file (suppose you want to create an executable named project.exe in D: directory then your path to output file would be D: project.exe ). But if no JRE is found in this search path, launch4j displays the error message 'This application was configured to use a bundled Java Runtime Environment but the runtime is missing or corrupted.' That error message isn't accurate, so it could be confusing to end-users. Run launch4j.exe or launch4j script without command line arguments to enter the GUI mode. Launch4j.exe To wrap a jar in console mode use launch4jc.exe and specify the configuration file.
Program consists on one uber jar via maven-shade plugin and a Data/ Runs fine on any jre7 machine, windows or linux
However I've been unable to get launch4j to work.
launch4j config.xml:
Then to build, on windows, I try this:
It's at this point that I get a nice little window about how it failed to find the JRE.
Java is in K:testjre7binjava.exe My jar is K:testpllsolver-0.2alpha.jar
Additionally, I don't know if this will be an issue yet, but the executable and the Data/ need to be in the same directory. I'm planning to do better pathing later but I don't have a clear understanding of Windows ENV variables.
a bit late but maybe it can still help you ...
One thing which works for sure with launch4j and JRE is to bundle the JRE in the folder of your application.
To do so:
- create a path 'jre' in the folder with your '*.exe'
- copy a JRE in this folder (this jre has to fit the 'min'/'max' conditions you have set)
- set '<path>/jre</path>' inside the <jre> configuration of your '.xml'
... this should work

It is part of the assembly code that handles the transition from user-space into kernel-space for a system call. It's simply a label to...

There are also leftOuterJoin, rightOuterJoin, and fullOuterJoin methods on RDD. So you have to map both datasets to...
