Basically, I?m trying to install rJava on my windows XP machine. I think I
have succeeded in doing so as it appears in the list when i type library()
in R.
However, when i type ?library(rJava)? I get an error dialog box saying:
'This application has failed to start because jvm.dll was not found.
Re-installing the application may fix this problem'
When I press 'OK' on the dialog box, I get the following in the R
console:
Error in dyn.load(x, as.logical(local), as.logical(now)) :
unable to load shared library
'C:/PROGRA~1/R/R-25~1.0/library/rJava/libs/rJava.dll':
LoadLibrary failure: The specified module could not be found.
Error : .onLoad failed in 'loadNamespace' for 'rJava'
Error: package/namespace load failed for 'rJava'
Do you have any ideas how I can fix this? I really would appreciate any help
you could give me?
I have tried reinstalling it and I continue to get the same problem. I am
using java's jdk1.6.0_01
Thanks

Ah.... thanks for that. That seems to have done the trick. But I'm not sure whether I have copied the right jvm.dll file into the path. I have 3 places where a jvm.dll file can be found: ~\Java\jre1.6.0_01\bin\client - this is the one i copied ~\Java\jdk1.6.0_01\jre\bin\client ~\Java\jdk1.6.0_01\jre\bin\server Did I copy the right one? or do the all have exactly the same file but just placed in different directories?

Could someone please tell me where I can find a simple example, which does
not require linux!, on how I can see if this is working and get me started
using rJava. I have read the document 'Getting Started with the
R-Java/Omegahat Interface' and have tried to type in things such as
.JavaConstructor("JButton", "A button") in the R console
after loading
library(rJava). However i keep getting the error:
Error: could not find function ".JavaConstructor"
Any help would be so greatly appreciated.
Thanks

Ah ok, thanks. However (again!), when i try to strat the jvm using .jinit() I don't seem to be able to as I get the message: Error in .jinit() : Cannot create Java Virtual Machine What is going on here?
