Subject: Re: [xsl] How do I set up my Saxon call to update/pass back a log file From: "Wolfgang Laun wolfgang.laun@xxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Tue, 17 Mar 2015 11:37:44 -0000 |
There's really no need to write a shell script or a Java program to have a list of users notified when your Java call to execute a Saxon transformation misbehaves. When you edit the crontab job (crontab -e), include an environment definition for variable MAILTO with a list of mail addresses, followed by the crontab entry for calling Saxon. I'm using a script since this simplifies tuning the details of the call: MAILTO = cwilbur@xxxxxxxxxxx,jdoe@xxxxxxxxxxx,psmith@xxxxxxxxxxx 0 12 * * * /home/auser/saxon/call.sh The script should use redirection (*2>&1*): #! /bin/bash cd /home/auser/saxon /extra/JDK8u20/jdk1.8.0_20/bin/java \ -cp /extra/saxon/saxon9he.jar net.sf.saxon.Transform -s:call.xml -xsl:call.xsl -o:call.csv 2>&1 Users will only receive mail if something is written to standard output or standard error.
