    How to stop java security warning?

          Sign your custom jars with known and trusted certificates (e.g. Verisign, Thawte, etc).

            I have the same issue with a brand new forms install with no custom jar files. I

            think the only way to stop it is to put the urls in the java control panel

            security exceptions. you need to include the port number(s).


            After I said that I found that it still put out the security warning. But it was possible to stop it by running javaws ( jre1.8.0_202) from the command line wherein

            it has an option to stop outputting the message. However this was url-specific. If anything differed, it comes up with it again.  See above. javaws.png


            It is a complete mystery why this happens. I had thought it was because the cert expired. But frmall.jar at least was timestamped.

            jarsigner  -verify -verbose -certs frmall.jar >foo

            "The signer certificate expired on 2018-02-01. However, the JAR will be valid until the timestamp expires on 2020-12-29"

            There definitely will be a problem after 12/29/2020 so we might as well get used to it. :-)

              Can you verify your Java IE 11 plugin with https://www.java.com/en/download/installed.jsp ?

                The only way I might anticipate this happening on a new installation would be if you are not using  Note that custom jar files include your own Java Beans or PJCs, icon/image jar files, and even jacob.jar.  Anything that is not delivered with the installation and requires you to sign becomes an issue.  You cannot use sign_webutil.bat/sh.  You must use a real certificate that came from a CA.


                You can use the Site Exception list to avoid some of the messaging, but not all messages.  To avoid most of the messages you would need to use a Deployment Rule Set, but it needs to be properly signed too.

                  I don't know what jars it is looking at. In the formsweb.cfg I have:




                  same as for the webstart entry. So is it not just frmall.jar like below? The extensions.jnlp file

                  specifies no other jars.


                  Now I am more unhappy about the fact that java wants to update.

                  Java(TM) SE Runtime Environment (build 1.8.0_202-b26) downloaded from oracle support.

                  see attached where ie wants it to update.  I fear it would update to a version beyond 8. Anyone let it do the update to see what it is going to do?

                  Looking at the base.jnlp which I have no idea about how it works, this part worries me:


                       <!-- Application Resources -->

                       <j2se version="%java_version%" href="http://java.sun.com/products/autodl/j2se"/>

                       <jfx:javafx-runtime version="2.2+"/>

                       <jar href="%contextRoot%/java/frmall.jar" download="eager" main="true" />

                       <extension name="Extensions" href="%contextRoot%/java/extensions.jnlp"/>


                  Is it telling it to go find a current version of java? We certainly do not want the current version. I think it was but now that url doesn't work thankfully.

                  If it is just going to 8u211 it's ok but historically java will try to update a lot more than that like 12.0.1java8u220.png

                    You won't/can't be updated to anything but 8 because newer versions do not support Autoupdate.
