HI Mohineesh,

We'll need a bit more detail to respond to this.

Which specific view are you looking at? What is the view name?

Cheers

Neil

The Essential Project sponsors, EAS, provide professional services to support this kind of activity. They can also provide view development training for those who wish to learn to do this themselves. You can get in touch with them via the Services Menu at the top of this page. If you want to try to ...

Hi Mohineesh, This is a common error when first using Essential and is typically the result of something going wrong during the install. A couple of quick questions... Is Tomcat running? i.e. if you visit [url]http:://localhost:8080[/url] do you see the standard Tomcat page? If not, then try startin...

The tutorials are for v1.x of Essential and although they apply in principal to v3, there may be some differences. Do feel free to follow them but don't be surprised if some things have changed. We will update the tutorials but for now these are the only ones we have ready. EAS do offer formal train...

Apologies for taking a while to get around to this - it dropped of the queue for some reason.... Can you post the entire xsl as an attachment as the snippet refers to parts of the view which I can't see. I'm guessing this is added to an existing view - if so which one? I suspect from your code the i...

Hi, Thanks for this. It's quite similar to ideas we've looked at developing. In fact v3 viewer has a hidden search box in the header which is current not linked to anything. This could be tweaked to pass the parameter to the view you've created. When I downloaded the file, it was actually an XML not...

That's great news Michael.

It sounds like the reportXML file isn't being updated properly. You can check the Tomcat logs to see if you're getting any errors. Tomcat > Logs > Catalina.out is a good place to start. Sometimes, these can be due to not enough memory allocated to Tomcat or Protege. We typically allocate 1536mb to t...

Just a brief response on this.... Single vs Multi user will have no effect per se on Essential Viewer. However the context menu lists are repository driven therefore it requires a recent repository (i.e. a version 3 repository) in order to work. Are your single user / multi-user repositories differe...

I have a multi user install on a single machine which I use for development and testing. Many multi user installs only ever exist on a single machine. I'd suggest you run through the install process and if you get any problems then post your questions here.

Thanks

Neil

Hi Saïd, It sounds like you have things configured correctly. The "Success" messages means that Protege is able to talk to the Essential Viewer web app. A few questions... When you go to the URL http://localhost:8080/essential_viewer/ Do you see the Essential Viewer Homepage? If so, which ...

Hi, This is a popular question and Jon has posted a great reply and blog post on this before. http://www.enterprise-architecture.org/forums/viewtopic.php?f=6&t=161&p=893&hilit=owl#p893 http://www.enterprise-architecture.org/blogs/2010/07/16/what-about-owl/ If you have any further questio...

Hi Steve, The "implemented" field on the "Implemented Applications" section of the "Application Service Summary" refers to the "Application Functions" of an Application not the Application itself. In the protege repository the slot "Provides Application F...

Hi Fabrizio, I've just answered a similar question a few days ago... We're aware of the lack of example content for v3 and are working on getting a new demo repository together. As v3 was such a big leap forward there's quite a bit of work needed to get a great demo together. We had hoped to get a d...

Hi Paul, Thanks for your interest. We're aware of the lack of example content for v3 and are working on getting a new demo repository together. As v3 was such a big leap forward there's quite a bit of work needed to get a great demo together. We had hoped to get the demo available for launch but we ...

These slots do not exist in the current meta-model and therefore these are classed as a known bug with the view. We're reviewing the current bug list over the next few weeks and will try and put an update out shortly. This may either add the slots or remove them from the view.

Thanks

Neil

Hi, Let's see if we can help debug and understand whether it's an installation issue, a content/repository issue or a bug with the view. Would it be possible to post a screenshot of the error you're getting? I'd be able to narrow the bug down by understanding visually what's getting rendered. (use t...

Hi Sigi, We were discussing the issue your having here and we were having a bit of trouble understanding the issues and state of your current installation. Do you have a backup of the project prior to converting to multi-user? Is it possible you didn't save the project file after converting to multi...

Hi Ramesh, A quick thought... Did you install the Server Component when you did the Essential Install? This installs the default Meta Project (metaproject.pprj) into the folder {my protege instal}/examples/server This file will have the starter instances which you can configure for your installation...

Hi, I just wanted to let you know that we are now able to replicate this issue and have a workaround which I'll post shortly. We'll continue to investigate the problem and update the install guide once we fully understand the correct approach for this.

Cheers

Neil

Hi,

There are no views currently in the Support section. We've put this in place for future use. It sounds like you've restored everything back. It's also worth mentioning that you can restore to the default state by publishing from a v3 repository (even an empty one).

Cheers

Neil

Hi, We might need a little more information to help. Is the file located in a "user" directory e.g. Documents or Desktop? Depending on your configuration, you may need to run as an administrator (you can right click on the file for this option in Windows 7) Which Java runtime do you curren...

Hi Ramesh, Two quick points. Although we publish to the "report service" at http://localhost:8080/essential_viewer/reportService the correct url for the viewer is simply http://localhost:8080/essential_viewer. From there you access the different views available via the dedicated homepage. ...

For now, we have an internal solution however a public bug-tracker is something we'd like to do. We need set a bit of time aside to figure out the best approach for the Essential Project and then make it happen. We've been a bit busy recently :D We'll post back when we have a bit more to report... T...

Thanks for your feedback. I've added these to the bug tracker. This will be definitely fixed in the next minor release.

Cheers

Neil

Hi, We see Goals as longer term objectives and model them using the Objectives meta-class. However, we understand that there are scenarios where you might want to distinguish these separately and we use Taxonomy Terms to separate the kinds of objectives we have (for example, in a custom view). We ha...

Can you describe the path you take to try to view the page. This will help us debug. Like most pages, the Technology Instance Summary page has been renamed in line with a standard naming convention. In this case it's technology/core_tl_tech_instance_summary.xsl I can view the instance summary on my ...

The Protege team have written a great page which explains more about file encoding within Protege and their choice of UTF-8.

http://protege.stanford.edu/doc/file_encodings.html

Is there any reason you're looking at the ISO-8859-1 standard?

Apologies, I wasn't quite clear enough. The encoding for the output is set in the file called ev3_common_head_content.xsl within the common folder. The following line sets the encoding for all the html output <meta http-equiv="content-type" content="text/html; charset=UTF-8" /> A...

The same problem applies really. Just by using this widget, it creates default styles in the output which overwrite the default Viewer styles which means you'll need to write a function to handle this. If you revert back to the TextAreaWidget you could use the HTML <br/> tag to force a line break in...

Thanks for the tip. All the xsl files in Essential Viewer have UTF-8 encoding. Is this proving a problem for any reason?

Hi, We made the decision to keep the separation of content and formatting between Protege and Viewer to allow a consistent look and feel across the whole of Essential Viewer. As a result we chose to use the TextAreaWidget rather than the EditorPaneWidget as this provides us with clean plain text whi...

I've attached a small snippet of the poster to aid discussion. TAM_snippet.png Firstly, I've not come across this before and at first glance, I'm unsure of what all the various colours and boxes mean in terms of relationships but I understand the general gist of the model. That said, these look to m...

Hi Rungsima,

I'm not familiar with the Telecom Application Map you mention. Can you provide a link or website to help us better answer you question.

Thanks

Neil

No problem... In the form editor left hand pane you will see 4 icons near the top. The first of these icons is "View Form Customisations". From here, you can set a widget type for each slot or you can set it to "none" which removes the slot widget from the form. Importantly, this...

Although I don't have any personal experience of running Essential under JBoss, I understand that some of the Protege team have used it successfully. Regarding v3 vs v4 of Protege, Jonathan has covered this in a previous post which should answer your question. http://www.enterprise-architecture.org/...

There isn't a set time for updating the roadmap. We update the roadmap when something changes e.g. a shift in demand or completion of phases of the roadmap, etc... If there are things you'd like to see on the roadmap then let us know. We're always looking to the community to help set the direction o...

That's great news. Thanks for the update

Hi Wolfgang,

To turn on the Forms tab (as well as many of the other tab options) goto "Project" from the main menu and choose "Configure" and select the "Tab Widgets" section.

Cheers

Neil

Hi Wolfgang, Just to build on Jon's answer a little more... You could use BIRT, though we don't currently. For some of our client work, we've used the following tools and they're straightforward to implement. We're using some of these in the release http://thejit.org/ http://mbostock.github.com/prot...

Hi Wolfgang, Typically, we provide separate upgrade scripts for version upgrades. Currently, these are run from the script tab within Protege though we're working on simplifying this even more. This current method isn't complex but can be prone to "user error" or typos so we thought we'd t...

Hi Wolfgang, Could you expand a little on the question... What is it you'd like to do when you say "group applications". How? For what purpose? Can you provide an example of what you might like? Essential can group applications in many different ways. If you provide a little more detail on...

quick one...

I think the 'essential_viewer.war' needs to be in the web apps folder. from there Tomcat should deploy the app and a folder should automatically appear called essential_viewer.

Yes Tomcat needs to be running...

Cheers

Neil

Ok... To define a deployment... 1. Choose the Application Provider you wish to define a deployment for. 2. In the form for the Application Provider, find the Physical Deployment field and choose Add New 3. You should now have a new form to create a deployment 4. Give the deployment a local name e.g....

Do let us know how you get on... I tried this and although the rendering wasn't quite as pretty as it should have been, it was quite usable. Only took about 5 mins to add too... Add this line of code as the first line in the <head> section <script src="js/svg.js" data-path="js/" ...

Hi schulmkg, Whilst it is true that the SVG plugin developed by Adobe for Internet Explorer is no longer being actively developed, it is a stable product and does (to the best of my knowledge) work fine in IE6, IE7 and IE8 for using Essential Viewer. In the new IE9, SVG support is baked directly int...

Just a brief thought that might help with your troubleshooting is to install to a folder in your users directory e.g. Documents. This will bypass the permissions issue and you will be able to ensure you have all the files you need. You can copy them manually if necessary. This does feel like a permi...
