java.lang.NoClassDefFoundError: javax/activation/DataSource #77

ghost · 2018-03-22T08:58:14Z

Trying to send an email after buying a new MacBook. I have updated all my packages, installed java9 but I am getting this error. I am using this package on another macbook with exactly same settings, so why is this not working?

send.mail(from = sender,
to = c("lrs.ngrd@gmail.com"),
subject = subject_line,
body = "/Users/larsnygaard/table_rank_eod/_html/email.html",
html = TRUE,
smtp = list(host.name = "smtp.webhuset.no", port = 143,user.name = "info@norquant.no",passwd = "xxxxxxx", ssl = TRUE),
authenticate = TRUE,
send = TRUE, debug = TRUE)

Error in .jnew("org.apache.commons.mail.HtmlEmail") :
java.lang.NoClassDefFoundError: javax/activation/DataSource

msrodrigues · 2018-03-29T23:40:10Z

I have the same problem, Error in .jnew("org.apache.commons.mail.ImageHtmlEmail") :
java.lang.NoClassDefFoundError: javax/activation/DataSource
looked everywhere... :(
I think it is a java path issue, did you discover anything?

Hellvince · 2018-03-30T09:07:02Z

Hi !
MailR was working fine on my previous laptop with Java8 installed.

I just got a brand new laptop, installed Java10, fired R/RStudio and... mailR wasn't working anymore.
Same error : java.lang.NoClassDefFoundError: javax/activation/DataSource

Quick fix : I installed Java8 (on top of the current Java10), modified the JAVA_HOME system variable to target the right Java version and... voilà ! mailR is working again.

IMO, it boils down to a Java version issue, at least partially.

vfulco · 2018-04-08T05:02:04Z

Same here on Ubuntu 16.04. Forced to upgrade to 18.04 and everything, this breaks and I know nothing about Java.

rpremraj · 2018-04-08T20:26:01Z

mailR will be updated in the coming days; I hope this issue will be resolved.

@Nygdat On my Mac, I use the Java version that comes with the OS. Installing newest Java version from Oracle resulted in a mess.

msrodrigues · 2018-04-11T03:31:47Z

mailR will be updated in the coming days; I hope this issue will be resolved.
This is exciting news! Will it still need java?

rpremraj · 2018-04-11T04:21:36Z

Sadly yes, because it depends on Commons Email (https://commons.apache.org/proper/commons-email/).

In future I will try to break away from this considering most issues reported here relate to Java.

shubhangisharma1742 · 2018-04-13T14:24:47Z

Hi, encountering same problem. reinstalled java 8 but still facing the same issue. Any suggestions?

NicolasNeiman · 2018-05-03T00:21:10Z

Hi, I'm having the same issue with Java 8
Any updates ?

Vancamjr · 2018-06-02T16:42:05Z

Same issue hoped to find a fix in-progress via install_github() -> nojoy [mac 10.13.4]
Agree: Freedom from Java would solve majority of headaches (a major adoption barrier).

rpremraj · 2018-06-03T16:14:33Z

Freedom from Java: Agreed!

I am forced to use Java 8 at work, and the package works well... Will upgrade Java libraries as interim solution to see whether it solves current issues.

mkroening · 2018-06-06T11:19:56Z

The Java EE modules are deprecated from Java 9 onwards:
http://openjdk.java.net/jeps/320
The general recommendation is providing those modules as dependencies.
https://maven.apache.org/surefire/maven-surefire-plugin/java9.html
To solve this particular problem it would be "javax.activation:javax.activation-api".

wx2000 · 2018-07-28T08:25:05Z

Hi, I'm having the same issue with Java 9
Any updates ?

ghost · 2018-08-11T04:54:16Z

+1 looking forward to the update...

scottyraymond · 2018-08-31T15:53:50Z

@Hellvince thank you very much for your comment. I was able to take the following steps based on your suggestion. I am using Windows 10, RStudio Version 1.1.456, and R version 3.5.1 (2018-07-02)

Download and install JDK 8:
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Check if the JAVA_HOME system variable exists or is set from R:

Sys.getenv("JAVA_HOME") # (In my case it was "")

Open a command prompt or Power Shell as an Administrator and enter the following command

rundll32.exe sysdm.cpl,EditEnvironmentVariables

Add a new environment variable for "JAVA_HOME"
JAVA_HOME = C:\Program Files\Java\jdk1.8.0_181\jre

Restart RStudio

From there I was able to send emails using:

library(mailR)
send.mail( ... ) # Here I was sending emails requiring authentication with a user.name and passwd

I also used debug = TRUE just to see everything was working.

advait1987 · 2018-09-18T07:54:41Z

I have tried with JAVA11, JAVA 8. But still get following error.
Error in .jnew("org.apache.commons.mail.ImageHtmlEmail") :
java.lang.NoClassDefFoundError: javax/activation/DataSource

FYI:

Sys.getenv("JAVA_HOME")
[1] "/usr/lib/jvm/java-8-oracle"

emiliotorres · 2019-01-10T00:24:00Z

Same problem here. Unable to configure the rJava package. I had to send a lot of emails and I did a workaround: If you are using Linux, you can use mutt, a program to send emails (sudo apt install mutt).

Remember to change the config of muttrc in the following function:

password <- "xxx"
to <- c("m1@gmail.com","m2@gmail.com")
subject <- "test"
body.file <- "body.txt"
attach.files <- c("f1.png","f2.png")
CC <- c("a1@gmail.com","a2@gmail.com")
BCC <- NULL

send_email(password,to,subject,body.file,attach.files=attach.files,CC=CC)

send_email <- function(password,to,subject,body.file,attach.files=NULL,CC=NULL,BCC=NULL){
    ## sudo apt install mutt
    dotmuttrc <- tempfile("muttrc") ##"~/.muttrc"
    configdotmuttrc <- paste0(
        "set smtp_pass=\"",password,"\"\n",
        "set smtp_url='smtp://me@mycompany.com@smtp.office365.com:587/'
set hostname = mycompany.com
set ssl_force_tls = yes
set smtp_authenticators = 'login'
set from = 'me@mycompany.com'\n"
)
    cat(configdotmuttrc,file=dotmuttrc)
    command <- paste0("mutt -F ", dotmuttrc," -s '",subject,"' ")
    if(!is.null(CC)) command <- paste(command ,paste(paste0(" -c ", CC),collapse=" "))
    if(!is.null(BCC)) command <- paste(command ,paste(paste0(" -b ", BCC),collapse=" "))
    if(!is.null(attach.files)) command <- paste(command ,paste(paste0(" -a ", attach.files),collapse=" "), " -- ")
    command <- paste(command,paste(to,collapse= " "))
    command <- paste(command, " < ", body.file)
    system(command)
}

Hi @rpremraj any news on this topic? I have the same issue with R 3.5.0 / mailR / Java 11. Thanks!

wush978 · 2019-02-20T20:30:00Z

After putting following two jars into system.file("java", package = "mailR"), the issue is resolved on my computer:

Linux Mint 19.2 x86_64-pc-linux-gnu
Kernel: 4.15.0-58-generic
R version: 3.6.1 (2019-07-05)
RSstudio version: 1.2.1335

The same error here

 Error in .jnew("org.apache.commons.mail.ImageHtmlEmail") : 
 java.lang.NoClassDefFoundError: javax/activation/DataSource

If I run
Sys.getenv("JAVA_HOME") ir returns ""
after setting with Sys.setenv(JAVA_HOME="/usr/lib/jvm/default-java"); Sys.getenv("JAVA_HOME") returns "/usr/lib/jvm/default-java"
But after restart of RStudio the command Sys.getenv("JAVA_HOME") returns again ""

Any ideas how to solve the issue under Linux?

filak · 2020-04-30T22:26:47Z

Thanks to @wush978 I was able to locate the missing jars.

Just download it and copy it to the ...\R-3.6.2\library\mailR\java\ folder.

Important - restart R after copying the jars.

The following JAVA versions seems to work:

#Sys.setenv(JAVA_HOME="C:\java\AdoptOpenJDK\jdk-11.0.6.10-hotspot");
#Sys.setenv(JAVA_HOME="C:\java\AmazonCorretto11\jdk11.0.7_10");
#Sys.setenv(JAVA_HOME="C:\java\OpenJDK8\jdk8u252-b09");
#Sys.setenv(JAVA_HOME="c:\java\Oracle\jre1.8.0_251");
Sys.getenv("JAVA_HOME")

Depois de colocar os seguintes dois frascos system.file("java", package = "mailR"), o problema foi resolvido no meu computador:

https://mvnrepository.com/artifact/javax.activation/javax.activation-api/1.2.0

https://mvnrepository.com/artifact/com.sun.activation/javax.activation/1.2.0

Obrigado, Tbm adicionei ao projeto e funcionou!

Thanks @wush978 , after doing this restarting R in R studio worked for me, but you have to install Java 8 and configure it to be default java using update-alternatives.
Downloading these jars without user-agent is difficult, so enable a ssh link between this and your local, Download them into your local and secure copy them into remote R server where this issue persists.
