Error: Could not find or load main class $JAVA_OPTS

Hello,

I tried to setup my first ciphermail on an CetOS 7 based virtual
machine, like described here:
https://www.ciphermail.com/documents/quick-install-guide.txt

If I try to start tomcat the following error occurred:

"Error: Could not find or load main class $JAVA_OPTS" What's wrong?
Where could be the nasty bug? Any idea?

Hi Django,

Can you show the contents of the file /etc/sysconfig/tomcat ?

Kind regards,

On CentOS 7 with Tomcat 7 should it be like that:

JAVA_OPTS="-Ddjigzo-web.home=/usr/share/djigzo-web"
JAVA_OPTS="-Djava.awt.headless=true -Xmx128M"

Isn't it so? :confused: I'm not a grait tomcat guru!

Something has changed with Tomcat 7 on CentOS 7. Somehow the sysconfig
file for tomcat no longer understands $JAVA_OPTS. Probably the
systconfig file is no longer included as a shell script (this used to
work, not sure when this was changed).

The solution is to set the JAVA_OPTS in one line:

JAVA_OPTS="-Ddjigzo-web.home=/usr/share/djigzo-web
-Djava.awt.headless=true -Xmx128M"

After a restart the first time the GUI is activated, it takes some time
to login. I think that the generation of some SSL DH keys takes some
time after a restart.

Kind regards,

Almost correct. I think by setting JAVA_OPTS like that will override the
previous setting. That's why it was using $JAVA_OPTS to make sure the
new value got appended. But, it might be that they completely changed
this during a minor update :frowning: .. because using $JAVA_OPTS used to work
correctly. I'll investigate this.

Kind regards,

Martijn

It looks like RedHat changed the Tomcat service to start with systemd.
The file /etc/sysconfig/tomcat is now loaded with the EnvironmentFile
directive and this does not support $ var expansion.

See Environment @
http://www.freedesktop.org/software/systemd/man/systemd.exec.html

I'll update the documentation.

Thanks for reporting.

Kind regards,

HI Martijn!

I'll update the documentation.

O.K. that's grait. BTW, you should rename (remove .deb) on your
downloadpage:
Community Edition packages

old:
- ------------------------------------------------------
RedHat & CentOS
Description File Signature
Back-end djigzo-2.10.0-3.noarch.rpm.deb
Web GUI djigzo-web-2.10.0-3.noarch.rpm.deb

Thanks for reporting.

No problem.

Hav a nice weekend!

You are right. You are the first to spot this :slight_smile: the actual link is
correct (i.e., the downloaded file does not have the .deb extension) but
the link text is not correct.

I'll fix this.

Thanks
