I've copied all the code from here but instead of looking like the sample it looks like the below screenshot. Obviously I'm missing something fundamental but being completely green in Java, GXT, and web development I'm unsure where to start. Any pointers gratefully received.
Are you using GXT 2 or 3?
Check to ensure the gxt-all.css file is loading correctly. I'm assuming you copied the gxt resources in to your project, and you're referencing their CSS file in your host/entry point page.
for a gxt development i sugest to use eclipse. i dont know which editor you are using. did you delete some image.

I am beginning at Java GUI, so I ask you professional coders to be understading towards to my humble question.
So, I have been coding this small Java project. I came across a problem, which is to query a Json file. During my quest over the internet looking for an answer, I stumbled upon this project on github:
https://github.com/json-path/JsonPath
Which proved to be the solution for my problem. Everything I need to be able to search for specific nodes on a json file is there, hard coded.
My beginner question: Is that possible to include this 'JsonPath' in my existing project? The IDE is Apache Netbeans 10.0 and the project is a Java SE application.
Thanks in advance!
I tried searching Services->Maven repository->Find...
I happened to find this package but I have no clue how to add the package. Also, I am not sure if its possible to add it to my project.
At first I thought doing something like "com.jayway.jsonpath" to my main class would solve my problem - But obvisouly it didn't, that's why I'm asking you guys for some guidance.
You're going to want to use a dependency management tool like Gradle or Maven first. This gives you a place to put all of the third-party dependencies like this one in your project. (Note: how to use or install either of those tools is outside of the scope of this question.)
Then, you just need the Maven coordinates. Luckily the project has those coordinates available.
I wanted to learn how to make a simple Spring+Hibernate+MySQL CRUD.
I found a tutorial. I wanted to run it on my PC first(to check if it's working and then learn what particular lines do). I downloaded the zip file and changed couple of things like name of the package or name of the database, the Spring/Hibernate version and so on.
Unfortunately the program is not working.
Of course there is a possibility that the tutorial is somewhere wrong but I bet that it's me not the tutorial that screwed something up.
If anybody have some free time I will really appreciate any help :)
This is a link to a github repo where I put code.
I use Eclipse and Tomcat 9.
Thank you in advance!
There is a lot easier way to get started with Spring completly from a scratch.
It's called Spring Boot and it is composed of an embedded servlet engine (Tomcat) and takes care of configuration of almost everything.
It doesn't require XML configuration which is a blessing and makes you feel like 2017, not 2000.
I found this video tutorial a very useful one and I can recommend it to you:
https://www.youtube.com/watch?v=vgPkUVF862g
Also, this series of video tutorials is excellent and explains everything about Spring MVC and Spring Boot, but it seems that first video is missing..

I tested on hiding the entire design of Notes and XPages application with Replace Design (Hidden formula and script option). As a result, some XPages processes don't work.
If any tool, please suggest in details.
I did as you suggested in above blog post (Wissel,net). But I encountered same as the last comment of it (Stefan Zehnder). I tested by opening a XPage in which some custom controls as referred to a jar file (custom controls class in xsp package). As a result, I cannot see them in the xPage. Maybe the “composite-file” property in the xsp-config file (in WEB-INF) points to the wrong file or class. If you have any idea, please kindly help.
If I understand your question correctly, then I would suggest looking at the responses to a similar question HERE
Also, the following blog post by Stephan Wissel might give you some ideas?
Sorry this question might look a bit vague. But my problem description is I want to build an xForm editor (preferably in GWT). I would be very grateful if someone can suggest me some hints, links or material that I should be looking into to answer my following questions.
How I can generate the equivalent xml code as I drag and drop the controls in the editor?
And then how to ensure that this generated xml adheres to the xforms schema definition?
You can see how Orbeon Form builder works and if you think you want to develop something similar to that, then try looking at the code. Since Orbeon is open source developed on Java/J2EE you can get the source code. This would be a good starting point.
Cheers.
I have a maven project imported into Eclipse. I'm trying to understand the code pattern (architecture). What is the best way to do this?
will use any UML Eclipse plugin help on this?
will use sequence diagram, help on this?
what plugins should I use?
Please share your opinion.
When I am working with a open source project/codebase I get a high-level view and focus on the core code/logic by checking the package names and structure. I then typically determine how the API works by looking at any example code / documentation contained in the project. If I still need some more help I will draw up some inheritance diagrams, print out interesting classes that I may need to make significant changes to, and try to find more examples of the code being used elsewhere.
I am biased and have been using our recently launched Architexa Eclipse plugin to accomplish the above. I am sure there are others available that do something similar.
I guess you will find some pointers in this SE-Radio podcast: Episode 148: Software Archaeology with Dave Thomas.
Of course, UML can help, but on the other side, it might not as well. For reverse engineering, there is the MoDisco project in Eclipse, which might be useful.
