Any tips on debugging Bean Shell scripts?

Confluence User - 23 Apr, 2021

I'm looking for a way to inspect values within my script.

Is there a simple way to just output a string to the log in runtime?

LogUtil seems to require an exception....i just want to do something like method("some string") or some variable value shows up in the log...

beanshell;debug;log

System.out.println(variable here);

I also recommend that if you are developing or testing you regularly dump the catalina.out file. Don't delete it, just assign an empty string (so as not to lose the permissions). On Linux:

sudo echo -n "" > catalina.out

I am using the On-Demand environment and examining the 'Logs' section (below the Performance' module.

System.out.println("hello world");

doesn't appear in the log.

Ok, i found out how...


In the bean shell script:

import org.joget.commons.util.LogUtil;
.
.
LogUtil.info("ClassName","Message");

Shoulda searched the KB deeper..found this.

Could be useful, haven't got a chance to test it out yet. Why clear the log regularly? is it for readability sake?

Instead of manually doing this, I would suggest using a utility like logrotate https://www.tecmint.com/install-logrotate-to-manage-log-rotation-in-linux/

Interesting to keep in mind. BTW, i'm not experienced in working with programming for Tomcat stack.
