JWrapper build not running correctly.

Newbie & Debugging Questions
#1

After building and running the application file a load screen appears for a couple of seconds then disappears. After that, my program does not run.

I have tried setting up my project folder exactly like the example project from the jwrapper website. I am able to build and run the application from that example.

Not entirely sure if I have the XML correct or if I’m not creating my jar correctly.

Folder I copy jre into and run jwrapper (including jar and xml and everything else required):

http://www.4shared.com/zip/qOA-V1lnba/jwraptest.html

I go to this directory, type “java.exe -Xmx512m -jar jwrapper-00031607960.jar gameapp\jwrapper.xml” and it appears to build fine.

This is how I compiled:

javac -sourcepath $SRC -d $BIN Game.java Draw.java Frame.java

This is how I compiled jar (command line in bin dir):

jar -cvmf manifest.txt game.jar game

manifest was: "Main-Class: game.Game
"

Jar runs fine on its own. There is no error, I just can’t run the application from the build. It has a loading screen on the first run, but nothing after that. It pops up in processes but that’s about it.

should i really download linux jre mandatorily?

#3

Hahahaha what?

I am looking at packr now. No clue what’s going on with jwrapper.

Hopefully I can get past my own incompetence with packr.

#4

Forget it… :slight_smile:

Good to know.

Tell me, you specified 32 bit jre for both win tags?

#5

For jwrapper? Yeah I did:

Just to be sure, here it is what you meant?


<Windows32JRE>JRE-1.7/win32/jre1.7.0_05</Windows32JRE>

<Windows64JRE>JRE-1.7/win32/jre1.7.0_05</Windows64JRE>

yep

#7

Do you have any experience with packr?

I am kind of having the same problem with it ;D

I get this error during build:

SLF4J: Failed to load class “org.slf4j.impl.StaticLoggerBinder”
SLF4J: Defaulting to no operation (NOP) logger implementation

But it goes on with the build and seems to complete fine. That error/warning doesn’t seem too important ???

The app generated doesn’t run at all.

The jar runs fine. I have a question: do you just run the jar, and it runs the .exe for the JVM? Or am I doing something wrong…

the .json file…


{
    "platform": "windows",
    "jdk": "C:/dev/OpenJDK/openjdk-1.7.0-u60-unofficial-windows-i586-image.zip",
    "executable": "game-exe",
    "appjar": "C:/dev/gameapp/bin/game.jar",
    "mainclass": "game/Game",
    "vmargs": [
    	"-Xmx1G"
    ],
    "minimizejre": "soft",
    "outdir": "out-win"
}

Everything else is exactly the same as in OP

#8

I didn’t hear about that. I think I have ;D

I badly slept this night and gonna freaking out with specifying jre’s location.
I thought it’s enough to specify JAVA_HOME and JRE_HOME ::slight_smile:
and I can work with win jre …

#9

jar runs fine. Building exe in process

#10

Oh thanks so much! Are you using jwrapper or packr?

#11

I use jwrapper but exe shows splash once then nothing…

#12

Indeed…exactly my problem :confused:

#13

It’s the warning of ‘Simple Logging Facade for Java’. Nothing special.

#14

Hopefully someone who has experienced this issue before sees this post :confused:

#15

I tried them all. JSmooth is the only Windows native launcher that works properly for me. Launcher4j launches a java.exe process, which is most of the reason to be using a native launcher. Even JSmooth doesn’t work as a service and I don’t think works when wrapping a JRE. Also it generates a terrible icon, but I just change that using Resoruce Hacker. Commands to fix the icon:


ResHacker.exe -delete build/Clippy.exe, build/Clippy.exe, ICONGROUP, A, 1033
ResHacker.exe -delete build/Clippy.exe, build/Clippy.exe, ICONGROUP, A2, 1033
ResHacker.exe -add build/Clippy.exe, build/Clippy.exe, build/icon.ico, ICONGROUP, MAINICON, 0

So what options do I have when I want to wrap a JRE?

If I wanted to make a game in java, and release it so it has the best chance of running on someones system without the user worrying about having the correct jre installed?

#17

You can use Launch4j if you are ok with the process running as “java.exe”. I tried some other projects, but they were old and no longer maintained (JSmooth included). You can use packr or write your own launcher using packr as an example. packr is a good solution if you are bundling a JRE. It doesn’t do system JRE/JDK search at all, so isn’t an option if not bundling a JRE. packr is quite minimal and can be a bit frustrating if misconfigured, since it doesn’t have an option for a log file. What I did was build the native launcher from the VS project after setting it to be a console app so I can see the damned logging. Ultimately I wrote my own launcher for Spine, based on packr’s code.

#18

Interesting. Well it sounds like packr should work for me. But I’m having this problem where the exe wont even run, so I have no clue how to debug???

#19

I can’t even get the TestApp to build and run correctly. Were you able to do so? I have no idea what I’m doing wrong. I’ve tried rebuilding in 5 different ways since I woke up. (Talking about packr)

#20

TestApp? You just need to run packr as the docs show.
