B4J Question [RPi][ABMaterial] can't get the server to run manually

[Cableguy]

Hi guys...

The last few steps of this Odyssey of mine called Pi Server...

So I got to the point were everything is working...
Normal webpages are served by Apache, and WebApps are redirected to the ABM running server... IF, AND ONLY IF, I'm running the ABM webapp from the IDE, Bridge connected!!

I jut can't get the dahm .jar to run!

I have tried copying it to several folders in the pi, including the user "pi" root folder, and then trying to run it using sudo java -jar MyWebApp.jar

The command line seems to be busy for a few seconds and then comes to life again...
There are no visual signs that the server has started, no log in the console, nothing!

So... any thoughts???

I just keep re-running the Demo ABMaterial 1.05, in hope I get to find where the compiler is copying the demo.jar file to, BUT it just seems to NOT EXIST in the Raspi...
Can this be???
I ran 2 times the search feature os SCP on the entire file system of the pi and no sign of the Demo.jar file!!!!

Make sure to copy the www folder together with the jar file.

Though there should be always some messages printed when you start the server. What is the output of java -version ?

 

[Cableguy]

Seems like my PI just went corrupt over night, so I'll be picking up from my last backup... should be operational in a couple of hours, then I'll return to this, but if my memory serves me well, it something like 1.8.0_65.

I had tried several times copying the Jar file to a location in the pi and then run it, but NOTHING happened... nothing was shown in the command line.

Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)Java(TM) SE Runtime Environment (build 1.8.0_65-b17)java version "1.8.0_65"

 

[Erel]

What is the output of java -jar <your jar file> ?

Are you sure that you have created a non-ui project?

 

[Cableguy]

as I have stated, I am running th ABM 1.05 Demo unchanged, Bridge connected... all works OK...
BUT, if I try stand alone, doing sudo java -jar Demo.jar there's nothing outputted!!! not a single line!
command line just freezes for a minute (the cursor goes under the current command line, in disable state) and then comes alive again with a new blank command line

 

[Erel]

Try it with a simple non-ui jar and see what happens.

 

[Cableguy]

the Bridge.jar is one, and works perfect!

 

[Cableguy]

what's puzzling me too is that, when I run it from the IDE with Bridge, I can't find the Demo.jar anywhere on the PI!!

 

[Cableguy]

Here's a video showing the behaviour! I apologize for the low quality, but my device is FixedFocus, so in order to keep perceptible I had to keep some distance.

You can find the jar in the tempjars forum. It will be named AsyncInput1 or 2.

The actual text is not clear in the video.

 

[Cableguy]

I do have the asyncfile in temp... How do I run it manually?

 

[Erel]

java -jar filename

 

[Cableguy]

So no need for the jar extension in the filename!?

 

[Erel]

No.

 

[Cableguy]

same result as with Demo.jar....

The cursor goes below the command line, stays there for about 30sec and then a new command line is available...
Nothing is outputted to the console... my head is starting to give in!

 

[Erel]

B4J-Bridge is a regular B4J app. So it B4J-Bridge works then there is no reason for your apps not to work.

Create a new empty non-ui app that logs a message and check it.

 

[Cableguy]

Hi EREL...
It's me... again...

But this time to report SUCCESS!!!
I've been making a newbie mistake, and was compiling in DEBUG mode!!!!
Of course, the server only ran when connected through B4J-Bridge.
This came to me when I tried to run a on-going project directly from the device, without the IDE...
On the device, we get a nice "trying to connect to debugger" message... but with B4J we don't... So maybe a wish to be made.

Wow! That was a tricky one to catch... congrats!
