Firewall/Connectivity Requirements?

Post by Nick »

Currently testing OWS in corporate environment with a Vendor supplied JNPL and not behaving as expected. I believe we may have a firewall or connectivity issue indicated by;

1. Updating OWS always fails with a Connection reset;

... 23 more
Caused by: java.net.SocketException: Connection reset
at java.net.SocketInputStream.read(SocketInputStream.java:210)
at java.net.SocketInputStream.read(SocketInputStream.java:141)

at sun.security.ssl.SSLSocketInputRecord.decode(SSLSocketInputRecord.java:190)
at sun.security.ssl.SSLTransport.decode(SSLTransport.java:109)
... 20 more


And ows-settings.log will show handshake_failure;

[ITW-CORE][2022-01-20 15:37:56.390 GMT][ERROR][com.openwebstart.launcher.ControlPanelLauncher]
Error in possible update process
javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

2. When opening vendor JNPL with no JVM install the attempt to download a JVM will fail.

No remote runtime found, will check deactivated local runtimes.
Error while trying to find a remote version
Using NO_PROXY
Using NO_PROXY
Endpoint to request for Java runtimes: https://download-openwebstart.com/jvms.json
Trying to find remote Java runtime. Requested version: '1.8*' Requested vendor: '*' requested os: 'WIN32'
No local runtime found, will try to find remote runtime

Is there a guide/document I can direct our Network Team to that specifies any firewall/anti-Virus/endpoint monitoring settings that may need to be amended to allow OWS ro tun?

I'm not any sort of developer or network engineer - more Apps Support working with end-user to get OWS configured and working.

Thanks in advance

Hello Nick,

Which version of OWS are you using at present?

> 1. Updating OWS always fails with a Connection reset;

Just to clarify, you started itw-settings. Did you choose Updates > Check for Updates Now? Or do have the option "Check Automatically for Updates " checked.

Are you saying that itw-settings is failing while updating OWS to newer version?

Can you please send us the ows-settings.log file?

Can you please try if the following URL is working in browser?
https://download-openwebstart.com/updates/updates.xml?

> 2. When opening vendor JNPL with no JVM install the attempt to download a JVM will fail.

Can you please send us the jnlp and the OWS logs?

Does the following URL work in your browser? https://download-openwebstart.com/jvms.json

> Is there a guide/document I can direct our Network Team to that specifies any firewall/anti-Virus/endpoint

Please try the above to URLs in the browser and let us know if they succeed or fail. In case they fail you can ask your Sys Admin to find out why the above two URLs are failing.

> I'm not any sort of developer or network engineer - more Apps Support
Ok. we will try to help you.

Are you trying to use OWS in an enterprise environment?

Is/Was the same Jnlp working with Oracle Java Web start?

Hi Janak,

Thanks for reaching out.:

Which version of OWS are you using at present?
Open Webstart 1.5.0

> 1. Updating OWS always fails with a Connection reset;

"Check Automatically for Updates " is checked but the log files suggest the check fails.
"Check for Updates Now" will also fail - it appears to be the process for checking that fails- doesn't get as far identifying if a newer version exists.

https://download-openwebstart.com/updates/updates.xml? Works fine in a browser

> 2. When opening vendor JNPL with no JVM install the attempt to download a JVM will fail.

https://download-openwebstart.com/jvms.json also works in browser


Is/Was the same Jnlp working with Oracle Java Web start? - seeking clarification


Are you trying to use OWS in an enterprise environment?
Yes - So we have firewalls, Anti-Virus, Intrusion Protection in place and most users will connected to Network via VPN

Can you please send us the jnlp and the OWS logs?
I appreciate that this will limit the ability to provide support but I need to seek clarification on whether I can provide log and JNPL files and if I'll need to strip out a lot of our site specific detail.

Thank you.

So did you try the above mentioned URLs in a browser in the same environment (behid firewal, vpn etc) as where OWS is running?

If the URLs worked in browser then they should work in OWS too with same proxy setting if any in the browser.

If not the Jnlp at least send us the logs. If you don't want to send on Public forum, You can buy at least Basic Support https://openwebstart.com/support where by we can create a private forum for you.
