I am using push notification on Vaadin 8.1 and it works well, but when I try use Liferay 7 with Vaadin 8.1 push notification doesn't work well and it gives me javax.portlet.PortletException: com.vaadin.server.ServiceException: java.lang.IllegalStateException: Push is not available. see previous log messages for more information.
Is there a way use push notification on vaadin 8 with liferay 7 integration?
As far as I know, Vaadin Push does not work in a portlet environment and I haven't seen plans to make it fit.
I have found this sample app with push developed by a Vaadin guy for Liferay 6. For what I saw, this solution works only in single portlet apps.
Anyway, I suggest you to switch to a javascript-originated client polling, which creates a near-real-time push-like solution, using this simple and very well written extension here.

How can I remove the web component part of a Flutter project? I have a project that when it was created was automatically created with web support. Now I am 100% certain the app won't be used for web and I just want to remove support for it. Is there a command in the terminal to help me do that?
I tried checking through the other questions but the others were asking how to disable web support altogether. I just want to remove web support on one project.
In order to fix this, I followed this link. The reason why I can't recreate the project easily is that the project has grown so much that it would be a big hassle to move it into another project. This happened after we updated all of our libraries to their latest versions respectively.
FirestoreWeb caused our project to stop compiling but since we aren't using Flutter web and we don't plan to use it for this project, it wouldn't make sense for us to implement it.
This answer was posted as an edit to the question Remove Web Part from Existing Flutter Project by the OP kobowo under CC BY-SA 4.0.
I'm working on a product which is an RCP application based on Eclipse 3.x api. Now we are trying to move it to Eclipse 4.x. We are using some internal classes in our code. I've already read the tutorial provided by Vogella about migrating to Eclipse 4.x from 3.x, but I'm still not getting how to start.
We want to take advantage of the new Eclipse features, my main question is that we have good number of views, layouts in our old code, so what should be the approach I should follow. Also is there a way to create an application model from my older application using 3.x API.
I'm stuck and not getting how to proceed.
this really depends what you are trying to do. Do you just want to update your IDE? Or should the project be based on the e4 platform.
I recently updated a project from 3.x to the new IDE. This works very good, the compatibility layer does a good job and you are able to run the application with minimal changes. However if you do this, you cannot use the benefits of the e4 platform.
If you want to move your application to e4, thats more work to do. Mostly you will not want to touch all the old code, so there is a possiblity to have 3.x and e4 plugins run together in your application. Thats done with the e4 bridge and wrapper classes for old code. Most of the IDE views and editor are also still based on 3.x, so if you use them, the e4 bridge is also a good way to incorporate them.
Some information can be found here:

I've read both the tutorial.But I am stucked and got too much confused as to where to start from. Basically 3 features are there
1. css styling of widgets(which i understood and did a bit of it)
2. to introduce dependency injection in my code
3. to put the application model
What approach I should follow?
This document helped me in deciding which strategy to adopt. http://www.eclipse.org/forums/index.php/fa/17403/ for migration.Indicates clearly which strategy you should adopt based on your existing code structure.Hope it helps
We have developed an eclipse rcp application using 3.5 and are trying to move it to 4.2.1.
It is a simple RCP application with a view. On doing the basics and launching it I found that the setShellStyle(SWT.MIN) is not working anymore. Since it was a single view application, it didnt require re-sizing, hence we had disabled re-sizing using this API.
But with the new Eclipse (Eclipse 4.2.1), the re-size/maximize button is enabled even when this method is called. I have verified that other APIs called from here work (other than this I used setShowStatusLine(false) and setShowCoolBar(false).
Is this a known problem with Eclipse 4 or whether there is a different API to get this functionality working with this.
I appreciate any kind of help I can get here.?
I am new to sakai, i want to add my own tool in sakai source code like announcement,syllabus...etc That tool having some my own functionality for this what i have to do, how can i develop my own tool in sakai.
Thanks.
Use one of the archetypes to get you started, then customise it. When you are comfortable you can change the UI layer to be whatever you like.
https://confluence.sakaiproject.org/display/BOOT/Developer+Tools
If you are looking for a solid "base" tool shell to begin with tool development my recommendation would be to start here: "Sakai Wicket Maven Archetype". There are a few other very good archetypes available but are often outdated and may cause you some problems based on my experience. This has been the one I've had the most success with.
This uses Wicket but does not mean you have to use Wicket to develop further with it. Make sure to pull the 1.2 version as last check the binaries for the others were not available yet so replace -DarchetypeVersion=1.4.1 with -DarchetypeVersion=1.2 It will compile and deploy successfully as a tool "as-is" that you can modify as needed. It also allows you to code in Java to directly access the sakai API and pull from its database or even add your own tables. I've successfully used it with NetBeans 8.0.1 and MySQL 5.6 under Windows 7 with Maven 3.2.3 and Sakai 10.1.
The code is well-documented and is no-frills but with enough varied functional use examples to allow you to do "almost" anything you want. The wicket manual is 600+ pages but in my experience you should be able to accomplish a lot just by looking at the code in the archetype.
I would like to be able to create FogBugz cases directly straight from the editor in NetBeans. Specifically, I would like to be able to look at a JUnit run in the IDE, examine the failures and create cases directly using the information that is right in front of me (rather than cutting and pasting into a web browser, etc).
I see that NetBeans 6.5.1 ships with Bugzilla available by default and JIRA connectivity in some sort of beta form. Is there an equivalent FogBugz issue tracker?
PS: I am aware of the new plugin architecture of FogBugz 7. However, I have a realistic appreciation of the time that I would be able to commit to creating my own plugin for either NetBeans and / or FogBugz and I suspect that I would be able to make just enough of a partial solution to make my life worse rather than better.
It appears you may need to write one yourself, as they have plugins for Eclipse and Visual Studio, but not Netbeans.

I am not aware of such plugin. You're right that it is not trivial effort to write full-featured connector, but getting basic one is not that hard ... especially if you're already familiar with NetBeans plugin architecture. If you decide to go for it, take a look at FogBugz API instead of new FogBugz plugins. FogBugz API is used to talk to remote FogBugz repositories.
