B4J Question Run a jRDC2 on a VPS - java file cannot execute

[achtrade]

I'm starting the server with this:

nohup /home/mj/Apps/jre1.8.0_45/bin/java -jar jRDC.jar > nohup.out &

but I'm getting this error:

/home/mj/Apps/jre1.8.0_45/bin/java cannot execute binary file

I double checked that the java file has execute permission and that the file is in that path.

How can I fix this.

Thanks.

How are you running the old RDC?

 

[Ed Brown]

Try re-installing Java but make sure that the version being installed is 64bit

Transfer -> Transfer type -> then choose the Binary or Auto option

Have you tried the Binary option? Have you tried to re-install a 64bit version of Java?

Many developers run it on VPS.

How can you run the old RDC if you can't run java -version ? The problem has nothing to do with jRDC2. You are unable to run java itself.

Erel,

What could be the problem ? I did what your tutorial says

I'm using something like this:

nohup /home/mija/RDC-Server/jdk1.7.0_79/bin/java -cp .:libs/*:jdbc_driver/* anywheresoftware.b4a.remotedatabase.RemoteServer > nohup.out

With the new jRDC2 a did this:

1. Download this file jre-8u162-linux-x64.tar.gz from oracle.com
2. unzipped in my W10 PC using WINRAR
3. Uploaded all the unzipped files to my VPS using FILEZILLA

I executed this in the VPS

nohup /home/mija/Apps/jre1.8.0_45/bin/java -jar /home/mija/Apps/EatR/jRDC.jar > nohup.out

it's not running. My jRDC.jar is inside of a different folder "EatR". I tried with both java folder "jdk1.7.0_79" & "jre1.8.0_45" I got the same error:

/home/mija/Apps/jre1.8.0_45/bin/java: /home/mija/Apps/jre1.8.0_45/bin/java: cannot execute binary file

Are you even executing the java executable from the 8u162 version that you downloaded? All I see you mention is trying 7u79 and 8u45 (Post #16 you mention downloading 8u162, but the post above this one only seems to try 8u45 and 7u79).

 

[Erel]

How did you install Java 1.7.0_79 on the server? You should do the same think with Java 8 or 9.

This problem has nothing to do with RDC or jRDC2. You need to copy java to your server and be able to run it.

Start with running java -version.

If you were able to do it in the past then I don't understand why you are unable to do it now.

Maybe this tutorial can help.
