Hi,
I want to run the R-function ctree (package party) from Java over Rserve
with the following Java-Code:

try{
RConnection v = new RConnection();
v.voidEval("library(party)");
v.voidEval("try(load(\"C:\\Documents and Settings\\daten2.rda\"))");
v.voidEval("try(pdf(\"C:\\Documents and Settings\\test4.pdf\"))");

v.voidEval("plot
(ctree(ZF2~TKL_f+Regio_f+km1000+SF_f+Geschlecht_f+Alter_VN+Random,
data=daten2, weights=daten2$Tage,
controls=ctree_control(mincriterion=0.95,maxdepth=4,teststat=\"quad\",testtype=\"Bonferroni\")),
type=\"simple\")");     //line 6

v.voidEval("dev.off()");
}catch(RserveException e){e.printStackTrace();}


I get the error-message "voidEval failed" for the line 6!

What can I do? Although I know it`s a Java question I hope somebody can help
me.

Thanks, Max


P.S. RServe is working at a simpler example.
