Webutil - Jacob.jar blocked when using webstart

db12345Feb 9 2018 — edited Feb 21 2018

Hi,

I've setup a new Windows Server 2016 with Weblogic Server + Forms 12.2.1.3.0. Everything is working except for jacob.jar

Have downloaded jacob-1.18-M2.zip and followed all the instructions for setting it up and signing it using a private certificate.

(https://oracle-base.com/articles/12c/oracle-forms-and-reports-12c-configuration-notes#webutil-config)

It works fine when running the application as Applet in HTML and Standalone mode, but using webstart its blocked and prevents the application from starting.

Client PC is a Windows 7 Desktop running JRE 7.51 with the server added to the exception list.

Below are the logs from the Java console after launching webstart with trace level 5.

javaws "http://servername:9001/forms/frmservlet?config=dev_webstart"

Warning:

This jar contains entries whose signer certificate's ExtendedKeyUsage extension doesn't allow code signing.

This jar contains entries whose certificate chain is not validated.

Re-run with the -verbose and -certs options for more details.

The jar file is being signed by following the these instructions:

The webstart webutil forms config is:

[dev_webstart]

# Forms applet archive setting for other clients (Java Plugin, Appletviewer, etc)

archive=frmall.jar,Images.jar

# Forms runtime argument: which form module to run

form=logon.fmx

# Forms runtime argument: database connection details

userid=@dev.world

# System parameter: file setting environment variables for the Forms runtime processes

envFile=dev.env

basejnlp=webutil.jnlp

webstart=enabled

WebUtilArchive=jacob.jar,frmwebutil.jar

WebUtilLogging=off

WebUtilLoggingDetail=normal

WebUtilErrorMode=Alert

WebUtilDispatchMonitorInterval=5

WebUtilTrustInternal=true

WebUtilMaxTransferSize=16384

Is there a step that I'm missing or a configuration that needs to be changed.

Thanks

Daniel
