For the Tomcat users file, this page might help https://examples.javacodegeeks.com/java-development/enterprise-java/tomcat/tomcat-users-xml-configuration-example/ Modifying this file is an optional installation step thought. Regarding the next bit, I'm not sure exactly where you're stuck. You'll nee...

Hi kxp, Have you any experience with the Essential Project already? Did you try running the Standalone version? That's a good place to start before trying the multi-user version. If you already have some experience with Essential and want to proceed with the multi-user version can you let us know th...

Hi,
Thanks for the prompt. We had updated the page but it hadn't been published. It should be available now.

Hi John,

Yes, we only enable this upon request. I've set this for your account and created a ticket to confirm this with you.

Thanks

Hi Vijay, Are you using the Essential Standalone version (aka Essential in a box) from this page? https://enterprise-architecture.org/products/essential-open-source/essential-os-download/ What action are you doing when the error appears? Can you share some screenshots and steps to recreate the issue...

Files in the ext folder are not available to Open Source. If you are an Essential Cloud or Essential Docker customer, contact us via the Helpdesk and we can discuss further.

Hi,

Yes, it will be updated sometime next week. There's typically a 2-3 week lead time to updating Essential Open Source on GitHub following the cloud release.

Best regards

Neil Walsh

Have you tried restarting tomcat after the publish? Sometimes Tomcat fails to reload the application following the publish

Can you post the details of the catalina.out file?

Can I check you are using Java 8?

Hi, That sounds right. Ensure you have the 64bit version of Tomcat and a 64 bit JVM. https://tomcat.apache.org/download-90.cgi 32-bit/64-bit Windows Service Installer Also, is there anything in the catalina.out log? It may also be called catalina.SOMEDATE.log That log can often provide more useful i...

Hi,

Essential does not currently support role based access control via SAML. It's something we are interested in implementing in the future but it is not on our immediate roadmap.

Thanks

Neil

Just a quick follow on.... It may be worth downloading the "Essential in a Box" zip which contains Protege, Viewer, Java and Tomcat in a single folder. This doesn't require any installation or configuration. From here you can publish your repository to the included Viewer. From there, you ...

Hi, Publishing via SSL to a remote server has always been a challenge. At the heart of the problem is there are two Java applications which need to talk over SSL and therefore they need to share a certificate to communicate. This forum post has some further information. https://enterprise-architectu...

All sorted!

Great stuff. Thanks for the update.

Hi,

As mentioned on our download page, Essential only supports Java 8 and will likely cause issues such as the ones shown with any other version. You have Java 11 installed. Can you try installing Java 8 and see if the issues resolve themselves.

Thanks

Neil

Hi,

This is unusual error.

Did you recently make any configuration changes, e.g., enabling Collaboration features?

Have you been running the Collaboration features?

Can you confirm you are using Java 8 with this installation?

Are you seeing any related database errors?

Let me know,

Neil

Hi, This is not possible with the current implementation of the Viewer search functionality. The search query is passed as a URL parameter and is escaped. This removes anything that is not a "character" (e.g., a letter or number in this case). It's a fairly basic search right now and it is...

Hi, The Technology Platform Model View is no longer supported. This should be labelled as deprecated. That's a bug we'll address in the next release. I recommend you turn off the view and menu item to prevent this being shown. The Technology Strategy Alignment view looks like either you are accessin...

Can you try this pack....

This sounds like you have overlapping fields. We have noticed this with some recent changes.

To resolve this, go to the forms tab (if this is not visible then you can enable in the "configure" menu) then drag that either of the overlapping fields to somewhere else on the page.

Hi, Security with Essential Open Source can be implemented with the following dimensions: Repository access via Protege https://enterprise-architecture.org/university/configuring-the-metaproject/ Viewer access via Tomcat See attached document. controlling-access-to-essential-open-souce.pdf For more ...

You no longer need to generate these images. They are no longer used by any views. We will try to remove that option in a future release to avoid confusion.

Yes, that's correct.

Yes the whole folder. The folder constitutes a "plugin" which is not used by Essential. This was a plugin developed by the original developers of the open source Protege project.

Yes you can upgrade to the latest v9.x Tomcat

Can you confirm you are using Java 8 and not some later version?

Hi Mike,

We have been able to recreate this issue and will have a fix for this in the next Essential Docker release.

Thanks

Neil

Hi, I'm not sure what might cause this but the "encoding" part of the error suggests the operating system isn't configured for UTF8. This could be a "locale" configuration issue. Did you set the two VMs up with different locales? This stack exchange post might help your investiga...

Hi,
Thanks both for bringing this to our attention. We have released a revised update which should resolve this issue. Let me know how you both get on.

Hi,

That plugin is not used by Essential. We will remove that from the download in the next release. In the mean time you can delete the parent folder for this.

Thanks. All sorted

That's great. Thanks for letting us know.

Hi, There is no 50mb constraint (or similar) regarding Viewer or publishing. In fact, we have customers with reportXML files at more than 10 times that size. This means something else must be causing the problem. Some things you could check.... Is port 8080 open for inbound connections in the remote...

Hi Kirill, My apologies, I'm not 100% sure I know what you're asking for.

Can you provide a little more details (maybe links and/or screenshots) and I'll do my best to h...

Hi Mike,

Can I confirm you have repository admin or system admin rights?

Did you say you can delete the last snapshot but not others?

Can you provide some more detail on what class and instance caused the issue or if it happens all the time, do you remember what you were working on when this happened?

Awesome!

Thanks for the tip!

We have spent some time trying to recreate this but to no avail. We all mostly use Macs and have done for a long time and have never encountered anything like you describe. Other thoughts... You could try creating a temporary user account and running Protege in there? Does the same thing happen? You...

That's great to hear. Did you identify the issue?

Hi,

Did it fail with an error or just appear to hang?

This step may take any where from 10 mins to multiple hours to run depending on the repository size.

If it hasn't displayed an error then you might want to try leaving this running for a few hours.

Let me know

Thanks

Neil

Hi, I have attached zip file which breaks down the update into smaller pieces. Unzip the file and you will see 6 EUP files. They should be applied in the correct order (1-6). After applying each pack, save your project with a new name, close Protege and reopen the last saved version. This should get...

Hi, Are you running an Intel Mac or an Apple Silicon (ARM) Mac (M1, M2, etc)? Did you install the JVM for the relevant architecture (Intel vs Arm)? Given our own extensive use of Mac and Protege (for more than 10 years) where we haven't seen this, I wonder if some other app/utility is causing the is...

Have you changed/updated Viewer at all? If so, which version and where did you download from - GitHub or our Website?

Hi, We typically only release the major increments to open source e.g. v6.18, v6.19 etc and not the interim releases e.g. v6.18.x unless there is an issue which we feel justifies the effort of packaging the OS release. 6.19 will be available in Q4 2023 and will include all the interim patches of the...

Hi, I guess the key aspect of the error message is that it isn't saying "publish failed" but rather it is saying "no response". This typically means that Protege cannot connect to the Essential Viewer application in Tomcat. Before I proceed though, can I check you are definitely ...

Hi,

We are aware of this and hope to have this fix next week.

Thanks for raising this.

Taking a look, I can see you have posted about 20 different questions in the past few weeks, most of which have a response fairly quick...

Hi Thierry, Short answer, yes. Updates via API update the active repository but you need to republish for the changes to be reflected in the Viewer snapshot. We have do have a Publish API which you could use to automate the Publish frequency. Reach out to the Essential Support team and they will get...

Hi, Is your Essential Viewer WAR file in the Tomcat "webapps" folder called essential_viewer.war or essential_viewer_6162.war? The name of this file determines the URL you should use in Protege when publishing. You can either: 1. Rename the WAR file to essential_viewer.war in which case th...

Hi Gena,

My comment (back in 2013) was intended to indicate we would patch the documentation. We did do this as I can see the relevant lines in the View Manual for this view. The Org chart setup is usually a one time setup. Is this something else that you're having to work around.
