Dear friends,

please help me.

I have b4j installed on my win7-64bit and my app (JAR file) I can run on this system,
but I can't run it on win7-32bit.

Please I have read forum but I have not found the clear solution.

I am trying b4j with this version of JDK:
:\Program Files (x86)\Java\jdk1.7.0_11\bin\javac.exe
:\Program Files (x86)\Java\jdk1.7.0_65\bin\javac.exe

Everything is OK on 64 bit but not on 32bit
Which version of JDK is correct for both version of system = 64bit and 32bit?
Thank you very much

I had similar issues before, jar apps crashed when started on an old laptop. It turned out that RAM was broken(tested by Memtest86+)

Thank you Erel and friends,

I am doing something wrong. I have read on forum, that I can take the compiled file *.jar from OBJECTS folder and I can use this file on other computers. If I run myapp.jar on another comupter, then I see only new created DATA folder, but BIN and SRC folder is not created.

But it looks, that I must take all data from OBJECTS folder=
- BIN folder with files
- DATA folder with files
- SRC folder with files
- and files in OBJECTS folder with myapp.jar

This everything I need for running my app on other computers? It is true?
It does it mean that I cant use only myapp.jar.

Thank you very much
Best regards

It depends on your project, the resources(DB,img,text) accessed by your jar should also be copied to the right directories.

B4X:
SQLmainlogin.InitializeSQLite("f://, "mydb.db",False)
contmap = File.ReadMap(File.DirApp, "cont.txt")

mydb.db (F disk) and cont.txt(File.DirApp->OBJECTS folder) should be copied to right directories


dbutils._executetableview
This will help you to find out which resource is missing or if there is any bug (Line: xxx).
