Dear all,

 

I cannot make Lejos work on my Windows XP machine. I have followed all guidelines (I believe) but the problems persist.

 

1) I downloaded JSE 1.4.2 – 12 and installed it. It ended up in: C:\j2sdk1.4.2_12

 

2) downloaded Lejos 2.1.0 (latest version) and installed it in c:\lejos

 

3) My path contains: C:\j2sdk1.4.2_12\bin;%LEJOS_HOME%\bin

 

4) LEJOS_HOME variable defined to: C:\lejos

 

5) RCXTTY = COM1

 

6) lejosc view  - does not work if I do not define javac = C:\j2sdk1.4.2_12\bin\javac.exe  even though the path variable is OK. ???????????????????

 

7) lejosfirmdl works fine and downloads the jvm

 

8) lejos does only run if I define: java = C:\j2sdk1.4.2_12\bin\java.exe     How come????????????????

 

9) lejos view works.

 

10) I have tried to add: CLASSPATH environment variable:
set CLASSPATH=%CLASSPATH%;.;%LEJOS_HOME%/lib/classes.jar;%LEJOS_HOME%/lib/pcrcxcomm.jar

As the installation guide says (which does not seem necessary according to other documents)

 

11) When I run “lejos view” or “emu-lejos view” I get:

 

Exception reading view

        at js.tinyvm.TinyVM.main(TinyVM.java:251)

 

??????????????

 

Has anyone tried to install LEJOS from scratch on a Windows XP machine recently? Did it work – and what could be the reasons for the problems I have

 

Thanks in Advance.
