I am trying to combine Jaspersoft Studio with DeployR script. I am using this tutorial from Microsoft here which is in fact for iReport (the former solution of Jaspersoft Studio). I have added the necessary jar files as in tutorial to the class path, and deployed the R script in DeployR.
After running the report in Jasper there comes nothing on the report with no errors given. But I have a warning which says: No query executer factory class registered for deployrScript queries. So I guess the problem is that Jaspersoft Studio can not find the class for deployrScript, although this class jRQueryExecuter2 is in the class path!
In jrxml you can see the declaration:
<queryString language="deployrScript">
<![CDATA[<deployr url="http://127.0.0.1:8000/deployr">
<script filename="Cluster_Demo_Jasperserver.R" directory="root" author="testuser"/>
</deployr>]]>
</queryString>
The whole jrxml is:

and the R script:
library(cluster)
#uncomment these lines to test in standalone mode
dataset <- "mtcars"
clusters <- 4
clustering_type <- 'hclust'
plotwidth<-555
plotheight<-555
if (dataset == 'iris') {
data <- iris[,1:4]
df <-data.frame(data$Sepal.Length, data$Sepal.Width)
} else if (dataset == 'mtcars') {
data <- mtcars
df <-data.frame(data$drat, data$disp)
} else {
stop("Enter a valid dataset")
}
if (clustering_type == 'kmeans') {
fit <- kmeans(df, clusters)
png("cluster_output.png", width=plotwidth, height=plotheight);
clusplot(df, fit$cluster, color=TRUE, shade=TRUE, labels=0, lines=0, main = dataset)
dev.off()
} else if (clustering_type == "hclust") {
d <- dist(as.matrix(df))
fit <-hclust(d)
png("cluster_output.png", width=plotwidth, height=plotheight);
plot(fit, main = dataset)
dev.off()
} else {
stop ("enter a valid clustering type")
}
The DeployR code:
library(cluster)
#uncomment these lines to test in standalone mode
#dataset <- "iris"
#clusters <- 4
#clustering_type <- 'hclust'
#plotwidth<-555
#plotheight<-555
if (dataset == 'iris') {
data <- iris[,1:4]
df <-data.frame(data$Sepal.Length, data$Sepal.Width)
} else if (dataset == 'mtcars') {
data <- mtcars
df <-data.frame(data$drat, data$disp)
} else {
stop("Enter a valid dataset")
}
if (clustering_type == 'kmeans') {
fit <- kmeans(df, clusters)
png("cluster_output.png", width=plotwidth, height=plotheight);
clusplot(df, fit$cluster, color=TRUE, shade=TRUE, labels=0, lines=0, main = dataset)
dev.off()
} else if (clustering_type == "hclust") {
d <- dist(as.matrix(df))
fit <-hclust(d)
png("cluster_output.png", width=plotwidth, height=plotheight);
plot(fit, main = dataset)
dev.off()
} else {
stop ("enter a valid clustering type")
}
I have added net.sf.jasperreports.query.executer.factory.deployrScript=com.revo.deployr.client.jasper.factory.RQueryExecuterFactory to properties as suggested by Narcis, but still the REPORT1 field is empty and I get nothing in report.
My question is how can I add DeployR to Jaspersoft Studio?
