Hello there,

I'm new and at least i got the example to work. I try to deploy the language server of xtext to my own jetty webserver. But it doesn't open and i figured out, that with export of "...web" the web.xml is missing. The usual way to create it doesn't work (found in google). I don't know what to do. I need this language Server out of eclipse

thanks, Mark

hi

Do you use maven or grade
How did you create your war Project ?
What do you mean by "export"

And. What is the reasoning for the deployment. Can you elaborate on that.
Language servers usually run on the client e.g in a child process

Hi there,
I use gradle and build the example. The reason is, i have to access it via a servlet from a requirement management tool (Polarion/ master thesis). It has to work without eclipse. I right click on the "web"-folder and could export a war file (without web.xml) and run it on my own webserver. Probably i will have more troubles in the next weeks but i want to start with this problem.

a xtext language server is no web app. ist just an app. if you want something else you have to create that yourself. e.g. create a gradle war project (have a look what xtext create for xtext-web - but that one does not use language server at all) , create your servlet, etc

In the xtext- 5min example it's showed how to to start jetty webserver and access it via webbrowser. I want to do the same, but without eclipse. I don't find information for this. This works within eclipse. It uses the gradle-build script from the web-folder

yes but this (WEB) is not LS(P)

(1) create new project
(2) deselect eclipse
(3) select web
(4) select gradle

(5) go to org.xtext.example.mydsl.parent
(6) ./gradlew clean build -x test (might need workaround for https://github.com/eclipse/xtext/issues/1231)
(7)go to org.xtext.example.mydsl.parent/org.xtext.example.mydsl.web/build/libs
(8) get a war
(9) drop it onto jetty
http://localhost:8080/org.xtext.example.mydsl.web-1.0.0-SNAPSHOT/

the servlet has @WebServlet thus i am not sure if you need a web.xml at all
https://stackoverflow.com/questions/29475426/which-is-better-to-use-in-professionally-web-xmldeployment-descriptor-or-web
=> you need a web xml? have a look at https://guides.gradle.org/building-java-web-applications/

It works...thanks alot. Somehow I'm too stupid to deploy on a web Server. With the deploy feature of the tomcat it works. manually copy not. First problem solved

The next problem: Polarion wants a Eclipse PlugIn. When i choose Export ->Ecl.-Plugin i can't choose Web. So my intention is to modify the gradle script. But how?
the same functionality like in the war file in a eclipse plugin.
The struggle won't end the next weeks, i see.

what do you exactly mean. you can choose gradle as build system or maven.

My first intention was, that Polarion installs an Apache where I can deploy my language server. I tried first on a standalone Apache. But it also uses Eclipse as a background app and i have to deploy like a eclipse plugin. When I build it with Eport->PlugIn Development- ...and fragments, i get a very tiny file. The examples here in the company (they develop for Polarion but not with Xtext and without gradle. There are differences) are much bigger. I need much more files, what was in the war file i need in the Eclipse PlugIn too, and maybe other stuff. So my intention is to use the gradle build script which created me an war-file and modify it somehow to get this eclipse plugin.
For me it seems to be the simplest way, but...

thanks
Mark
