Hi,
this is just an update. After having it running on Linux, I thought I could debug around in the mac install,
maybe it helps to isolate the problem. here is what I tried so far to rule out any simple error:
-- First question: where does the error message come from?
function is isRReference in RReferenceCall.c:
/* #line 378 "RReferenceCall.cweb" */
jboolean
isRReference(jobject obj, JNIEnv *env)
{
jclass klass;
jboolean ans;
klass = VMENV FindClass(env, "org/omegahat/R/Java/RForeignReference");
if(!klass) {
PROBLEM "Can't find org.omegahat.R.Java.RForeignReference"
ERROR;
}
ans = VMENV IsInstanceOf(env, obj, klass);
//XX Do we need to release this klass.
return(ans);
}
conclusion: FindClass does not find it.
(So I would like to inspect the "env" variable, but don't know how to do this.)
-- Then, where is that class org.omegahat.R.Java.RForeignReference?
This class is compiled from /SJava/inst/org/omegahat/R/Java/RForeignReference.java and installed to
/Library/Frameworks/R.framework/Versions/2.10/Resources/library/SJava/org/omegahat/R/Java/
Does it contain the class? Yes:
$ javap -classpath . RForeignReference
Compiled from "RForeignReference.java"
public class org.omegahat.R.Java.RForeignReference extends org.omegahat.Interfaces.NativeInterface.ForeignReference{
static boolean LoadLibrary;
public org.omegahat.R.Java.RForeignReference(java.lang.String);
public org.omegahat.R.Java.RForeignReference(java.lang.String, org.omegahat.Interfaces.NativeInterface.OmegaInterfaceManager);
public org.omegahat.R.Java.RForeignReference(org.omegahat.Interfaces.NativeInterface.ForeignReference);
public org.omegahat.R.Java.RForeignReference(org.omegahat.Interfaces.NativeInterface.ForeignReference, org.omegahat.Interfaces.NativeInterface.OmegaInterfaceManager);
public java.lang.Object localEval(org.omegahat.Environment.Parser.Parse.List, java.lang.String, java.lang.String, java.lang.String[]) throws java.lang.Exception;
public native java.lang.Object reval(java.lang.String, java.lang.Object[], java.lang.String, java.lang.String, java.lang.String[]);
static {};
}
-- Is it on the classpath? Add this path explicitly to $CLASSPATH and set it during .JavaInit and turned on verbose=T:
Didn't work, looks as if the classpath setting is ignored.
> .JavaInit(default=javaConfig(classPath=c("/Library/Frameworks/R.framework/Versions/2.10/Resources/library/SJava/org/omegahat/R/Java/", javaConfig()@classPath)), verbose=T)

Got it

....
Error in .Java(v, "add", "A string element") :
Can't find org.omegahat.R.Java.RForeignReference
-- Put all classes into a jar file and added the jar file to the class path in .JavaInit
Didn't work.
So I'm giving up for now. Would really like to have this work and in principle it should, but something seems to be very odd on the mac :(
Thank you again, and sorry for this lengthy email.
Best
Michael

RForeignReference.class is among them and this would seem to be the purpose of the "<...>/SJava/org/.." entry in class path.
