Problem on using Java installer

[taurus72]

Hello,

I have setup a VM machine with Centos 7. In order to access the internet I use a proxy.
On running

Code: Select all

java -Dhttp.proxyHost=<proxy> -Dhttp.proxyPort=<proxy port> -jar OKMInstaller.jar

I get the following error:

- Downloading Tomcat: 8.5.24

Code: Select all

ERROR: sourceforge.net: Name or service not known

The OKMInstaller.log has the following entries:

Any ideas?

Yes, the problem is the DNS, seems you are not able to resolve sourceforge.net

I suggest configure proxy at OS level ( https://docs.openkm.com/kcenter/view/ok ... proxy.html ):
Configuration below is based on setting proxy configuration parameters in the JVM environment. There's another option what is configuring proxy at OS level, here are several option one of them is:

Edit your "/etc/bash.bashrc" file as root and put these lines at the end of your "/etc/bash.bashrc" file:

Code: Select all

export http_proxy=http://username:password@proxyserver.net:port/
export ftp_proxy=http://username:password@proxyserver.net:port/

But that probably will not solve the DNS issue and you can try with these addtional lines when starting jar:
If you have issues resolving DNS you can also try with this configuration what is trying to use Google DNS:

Code: Select all

 -Dsun.net.spi.nameservice.nameservers=8.8.8.8
 -Dsun.net.spi.nameservice.provider.1=dns,sun

I am using the VM machine with CentOS setup but I am facing issue when I try to install Java on it. So, I started using the various websites and then https://microsoftsupport.co/microsoft-support-uk/ suggested me about this forum. I have also chexcked about the DNS issue but it is completely fone. So, may I know any other solution from here?

Hello guys!!

I'm using Debian 10, And I have downloaded the Community version, and cannot install it doing java -jar OKMInstaller.run.
The message that I received is this:

Yes , My version of Java is newer that the required, I guessed it was not problem.

Please, can someone help me to solve this?

I really appreciate it.

Sincerely

Alfred

You have "Java version: 11.0.4" and you need "OpenJDK 1.8", the reason is without this version the tomcat what is installed with OpenKM will not work. Until the installer will detect this java version the installer not advance in the following steps.

what is your OS version because sure you can install version 1.8 ( check google -> OS name install openjdk 1.8 -> sure you will find)
