Jar can be found here

[orgads]

The problem is missing plugin.jar in classpath.

[vsnine]

On Fedora 21, adding the following before executing the jvpn.pl script solved this for me.
CLASSPATH="/usr/share/icedtea-web/plugin.jar"

[AdnanHodzic]

I have same problem on Debian Jessie (8.1).

Transfer went ok

Unable to start tncc.jar process at ./jvpn.pl line 743.

I've run:
export CLASSPATH="/usr/share/icedtea-web/plugin.jar"
before running jvpn.pl but without success.

Any other ideas?

[orgads]

Do you have icedtea-netx-common installed?

plugin.jar can be in /usr/share/icedtea-web/plugin.jar or /usr/lib/jvm/jdk-7-oracle-i586/jre/lib/plugin.jar. If you have one of them it should work.

[AdnanHodzic]

In the end I went with a different solution (openconnect).

If you're interested in my setup, please see my "Juniper/Pulse Secure VPN on Linux (2015 edition)" blog post.

[juliogc]

@AdnanHodzic unfortunately the openconnect didn't solve my problem.

@orgads I could easily solve this issue by changing the openjdk to the Oracle JDK.

On Ubuntu:

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java8-installer
$ sudo update-alternatives --config java

  Selection    Path                                            Priority   Status
------------------------------------------------------------
  0            /usr/lib/jvm/java-8-oracle/jre/bin/java          1081      auto mode
  1            /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/java   1081      manual mode
* 2            /usr/lib/jvm/java-8-oracle/jre/bin/java          1081      manual mode

Press <enter> to keep the current choice[*], or type selection number: 2

I was facing the same problem and could solve installing the package default-jre

sudo apt install default-jre
