I’m trying to send a file as an email attachment, but I keep getting an error. I can send the email itself successfully with the following code:`smtp="my smtp server"
myFrom="my email address"
subject="Test email from Ignition"
body="This is a test email"
html=0
to=["destination email"]
attachmentNames=[]
attachmentData=[]
timeout=60000
username="email account username"
password="email account password"
system.net.sendEmail(smtp,myFrom,subject,body,html,to,attachmentNames,attachmentData,timeout,username,password)`I then convert the file to an array of bytes using`attachmentData=system.file.readFileAsBytes("c:\\Temp\\Test.txt")
`but when I try to send it I get the following apparently truncated error:`java.lang.ClassCastException: Cannot coerce value '[B@4813cc' into type: class [[B`This is despite being able to write the array of bytes successfully to another file using `system.file.writeFile("c:\\Temp\\Test2.txt",attachmentData)
`

Actually, that error message isn’t truncated, just somewhat obscure.

What it’s saying is: “I can’t coerce this byte array into an array of byte arrays.” The “attachmentData” argument needs to be a list of byte arrays. Throw some square brackets around it in the invocation and you should be all set.

I tried the following:`attachmentData=[system.file.readFileAsBytes("c:\\Temp\\Test.txt")]`but get this error:[code]Traceback (innermost last):

The extension is .txt (it is a text file containing ‘abc’!).

The installed Java is Version 6 Update 18.

Hmm, I’ve only ever seen this once, on another customer’s machine, and the culprit there was Java 6u4. Just want to make sure we’re talking about the same thing - the version of Java running the Gateway. You can be certain about this version by checking it as it is reported in the Config section of the Gateway under System\>Status.

Yes, the Gateway reports ‘Sun Microsystems Inc. 1.6.0\_18’.

I can’t seem to replicate this…

There is a file under your Ignition installation %Install\_Dir%/contexts/main/core/gateway/activation.jar

Rename this file so that it doesn’t end in “.jar” like “activation.jar.x”

Restart your Gateway, try again and let me know if anything changes.

I renamed the file and restarted the Ignition service, but no change.

Ok, next thing to try: download the latest [JavaMail release](http://java.sun.com/products/javamail/downloads/index.html), extract the “mail.jar” file, and replace the one under contexts/main/core/gateway with the newer one. Restart the service and try again.

I replaced mail.jar but still no success, either with the activation.jar left alone or renamed.

That’s me until tomorrow I’m afraid.

For reference, the most recent stack trace (new mail.jar and activation.jar renamed) is as follows:[code]Traceback (innermost last):

Just adding my 2 cents worth…

Have a look at [http://www.jguru.com/faq/view.jsp?EID=237257](http://www.jguru.com/faq/view.jsp?EID=237257)  
I know it’s more about java but there is an entry in it that appears to present a solution for this type of problem.

It looks like my problem with email sending.

Code is:

```
##file config and data

```

#file name  
filename=“ping.txt”  
#path to file  
filepath=“C:\”  
#name of the attachment file? on recived message  
attachmentName=filename  
#data of the file  
attachmentData=system.file.readFileAsBytes(filepath+filename)

```
##email config

```

#address of POP server : encryption : port  
pop=“192.168.1.51:25:ssl”  
#my e-mail address  
[myfrom="test@192.168.1.51](mailto:myfrom=%22test@192.168.1.51)"  
#Title of the message  
subject=“Test”  
#Body of the message  
body=“this is to test mail send \n” + filepath + “\n”  
#enable html mode on message (0=No, 1=Yes)  
html=0  
#e-mail(s) to sent to  
to=[“test2@192.168.1.51”]  
##authentification on pop server (if exists)  
#username  
[username1="test@192.168.1.51](mailto:username1=%22test@192.168.1.51)"  
#passwod  
password1=“test”  
system.net.sendEmail(pop,myfrom,subject,body,html,to,[attachmentName],[attachmentData],username=username1,password=password1)

Ignition v7.6.0 (b1875)  
Java: Oracle Corporation 1.7.0\_21

Without the attachment I can send the email.

Maybe there is a solution like “finished using rasp”?

Thanks in advance

andrey, your issue is an error introduced in Ignition 7.6.0. It is fixed for Ignition 7.6.1 (rc2 or later).
