Java errors while running web_api_show_package

[EvgenyAU]

Hello all,

I am trying to run remotely Policy Visualization api from my Win10 station to export policies from MDM R80.30 to HTML.

Using the latest jar version from Github, receiving Java errors:

Exception in thread "main" java.lang.NullPointerException
at com.checkpoint.mgmt_api.objects.PolicyPackage.toJson(PolicyPackage.java:79)
at com.checkpoint.mgmt_api.objects.IndexView.toJson(IndexView.java:64)
at com.checkpoint.mgmt_api.examples.ShowPackageTool.buildIndexHtmlPage(ShowPackageTool.java:1606)
at com.checkpoint.mgmt_api.examples.ShowPackageTool.main(ShowPackageTool.java:184)

I tried both Oracle and 3d party Java with no luck.

Please advise.

Why not run this directly from the management server?

[EvgenyAU]

Because we don't have access to it. It is a big company with some strict and weird policies.

Did you follow the build instructions in the GitHub?
It has a few dependencies (including a specific library of ours).

No, I am using ready-to-use jar artifact mentioned in README. Do you reckon it makes any difference?

Hi Evgeny,

This exception may happen if the policy package doesn't have NAT layer. If so, try to execute tool again with parameter --show-nat-policy false

We will fix that issue in the next version of the tool.

Thanks,

It does have NAT layer.

But I managed to create tarball by running it remotely on MDM server rather than on CMA using the full command:

java -jar web_api_show_package-jar-with-dependencies.jar -c -m ADDRESS -d DOMAIN_NAME -k POLICY_NAME --show-threat-policy false

Thanks for your help.
