Note that we've worked around all of the issues with Skin Editor under Jetty - with a build dated August 18 or later, Skin Editor should work out of the box, with no missing styles or images, and without changing jetty-web.xml.

[Isomorphic]

The SmartClient SDK comes with an embedded version of Tomcat, and start scripts for various platforms (Windows, MacOS, Linux), so you just run one of those scripts and navigate to localhost:8080 (by default). No deployment involved. So unless you're not allowed to run software on your own machine, this is another approach that bypasses the whole GWT toolchain problem, in addition to just using the online Skin Editor, which again, should also be working for you now.

In both cases, once you have the skin how you want it, you just export it and apply it to the target project, or you can load it dynamically by just pointing to the URL where you've got the Skin Editor running.

If you want to continue to do battle with GWT, please also check whether those icons are missing from disk, as previously mentioned. Again, a GWT compile may be necessary, as that's what copies the relevant resources from the .jars we provide to the deployment where you're trying to use the Skin Editor.

If they are present, then we are probably looking at two more Jetty bugs:

1. it's lying to us about the relative path (inserted an extra slash)

2. it's refusing to load files when there is a double slash in a path (most engines handle this fine)

We can and will work around both, if only for other users, but again, setting up the Skin Editor inside a GWT environment, only to not use GWT at all, is not the approach we'd recommend here.

[tece321]

2. I hear you about the tool chain. But I would have to build a war file and deploy it to one of our Tomcat servers in order to remove the development chain. Then where is the new skin created? Out on a file system, in another site on which the Tomcat servers are running. You're just not considering the big/huge company environment and the million restrictions placed, (example my Compass war of earlier in the week).

The file : bultinds/sc/skins/Tahoe/skin_styles_editor.css exists on the file system - within the development environment. So why is there any "failed to load" error? Let's fix that...

Why do I see that error, and all the missing image errors too? And preview is not working. There are no skins being applied in my environment.
This is from the development console of Chrome:




Am not clear - sorry - by exactly what you mean by "you just start the server and that's it, it just works."

I'm familiar with running under eclipse development system, and with Tomcat deployments. What does "just start the server" mean? Sorry to be so unfamiliar with the process.

[Isomorphic]

Two other notes here:

1. we previously told you that we'd eliminated the third-party library that broke IPv6 access, so you should be able to use the online Skin Editor again

2. using the Skin Editor does not involve Java development, front end or backend, so while we make it possible to run the Skin Editor within an Eclipse, GWT and Jetty environment, all of those things just get in the way and do not provide any value. You have been struggling with a toolchain you will not be using.

So, if you have a reason to run the Skin Editor locally, you might just use the SmartClient SDK (which you are licensed to use as well), since there, you just start the server and that's it, it just works. GWT can't get in the way and break things.

[Isomorphic]

Hi Tony, sorry you had a problem with Jetty. That's an absurdly low POST limit, far lower than the defaults for other servlet engines. We'll be adding some docs warning about this, also, we've implemented a workaround so that you won't hit this limit in the Skin Editor.

That path with the double slashes, while ugly, should still have worked. Are you saying the file is present on disk? If not, you may need to run a GWT compile after adding the base skins that the Skin Editor starts from. The same is probably also true of the missing icons, which should have been present after a GWT compile once you included the tools module.

[tece321]

Hello? Anyone out there? This is not working for me yet.

[tece321]

When I attempt to load the NEWSkin I get this popup error:



Is this something else that needs to be fixed? I don't see anything in the developer console, or the adminConsole that reflects this error. I opened these consoles on the Skin Editor.

One can see a path error in the image. The path it is trying to access is "bultinds/sc//skins/Tahoe/skin_styles_editor.css" where it should be ( ? )
bultinds/sc/skins/Tahoe/skin_styles_editor.css" .

I'm not generating that. So I will search to see where it is coming from in the project..

Also I notice that the skin editor comes up with missing icon images. What's up with that? Don't see anything in the console indicating those issues though.

[tece321]

The RPCResponse class documentation discusses how to change the MAX Post size for a Tomcat internal service.

>> On internal networks, these limits can typically be safely raised or removed. With Tomcat, for example, you can remove the post limit by specifying the following attribute on the <Connector> element in conf/server.xml:

>> maxPostSize="-1" But this is being run in an eclipse development envir under jetty. The jetty google search came up with this url: https://www.eclipse.org/jetty/docume...form-size.html


I am uncertain how to modify this parameter for my development mode. Can you advise? Or do I have this entirely wrong?

How could the RPC post get this big to exceed 200000? Anyway that's a discussion for another time.

Ah...

I found this war/WEB-INF/jetty-web.xml. I suppose this is the appropriate place to make the change?

Yes, in case others come across this, or if you can add it to documentation, adding war/WEB-INF/jetty-web.xml with contents:

<Configure class="org.eclipse.jetty.webapp.WebAppContext">

      <Set name="maxFormContentSize">100000000</Set>
</Configure>

fixed that MAX Post size issue.

[tece321]

That is a screenshot of JUST the top left of the screen.

I figured that it might be a parameter setting that needed increase - but wondered if you had not run across the same in your testing and had made a fix in the release?

Anyway a Google search on "isc.RPCResponse.STATUS_MAX_POST_EXCEEDED" or "RPCResponse.STATUS_MAX_POST_EXCEEDED" or "STATUS_MAX_POST_EXCEEDED" came up blank. Just FYI. Had to do it the hard way, open the docs and find the Class RPCResponse myself. :-)

This is what I get when I try, just now, to login to the online skin editor:

Your server's POST message size-limit needs to be increased. Please see the docs on isc.RPCResponse.STATUS_MAX_POST_EXCEEDED.

I added the built-in-ds project to my workspace.

I 'Navigated' to the http://IP:port//builtinds/tools/skin...skinEditor.jsp and the Skin Editor came up.

I input a new Skin name, NewSkin and clicked the create and edit skin button. This is the result:

This is what my UI looks like (seems correct)



This is what the skin editor looks like:



What have I done wrong?

[Isomorphic]

This appears to be because one section of our code wasn't expecting an IPv6 address. We're looking into it, but in the meantime can you hit the server from an IPv4 address?

We've removed the JAR dependency incompatible with IPv6 so you may want to try using the Skin Editor again.

[Isomorphic]

Compass is invoked when you save a skin in the Skin Editor. The DataSource operation involved executes a server method that shells the command-line "compass compile <path-to-skin-template-dir>".

Assuming Compass is in your PATH, all should be well - you can test that by just running "compass" on your Linux command-line - if it's found, it should work from Skin Editor as well.

We'll add some of this information to the docs.

[tece321]

Convinced our IT department to install Compass. So we have command line support of the Compass tool in Linux.

If we ever get to a point where the Skin Editor needs to call Compass, how is this invoked and resolved in the browser? We have Compass on our Linux boxes, where one needs to set an appropriate ruby version number, and invoke Compass from /tools/bin/compass, where normally /tools/bin is in our Linux PATH. But how does the browser/Skin Editor access this command line version?

[Isomorphic]

You can just run both projects in parallel and load the skin from the project where it's being edited. That's probably simpler than changing your main application project to enable use of tools, then reversing that once you are ready to deploy.

Fear of the MIT license makes no sense. It doesn't require attribution (like BSD) and you can freely sublicense under different terms. It is essentially certain that your company is using MIT licensed code all over the place, the lawyers just don't know this.

You can process our SCSS files with any SASS implementation that supports SCSS, but right now the Skin Editor is set up to call Compass in particular, with it's particular way of receiving command-line arguments. If you wanted to use some other SASS implementation, that should be achievable with a small Feature Sponsorship.

If you can't install a SASS processor in-house, then we'd recommend just using the online Skin Editors. The IPv6 problem (due to a third-party library not handling IPv6) will be solved shortly.
