JaxRS client

[gege-fr]

Hi, i just discovered jsweet and it seems promising. I have a question : is there a way to consume JaxRS services ?

Since one point of having java to code the web page is to also have java server-side. I don't know if i'm alone but I think it's worth thinking about.

Maybe by generating jsweet wrapper over a maven-generated js or ts client ? Or re-using the pojos and parsing the jaxrs service definition and pojos ? Or generating a client from wadl ?

Well, I wanted to raise this topic.

Woah, what a fast guy! :)

I will give it a try this week-end. Seems a promising project.

Thanks for your contribution to JSweet.

@GegeFR: there seem to be some regressions in JSweet because of latest improvements... So it will be hard for me to find the time to test it in the coming days. I will tell you when I find the right time. You are indeed quite fast ;)

Don't worry take your time. I'll also try to use it in a small "real life" personnal project. Need to do a porfolio for my kitchen designer of a wife :-) I wanted to use a jsweet / jaxrs / mongo stack an see if all's falling in place easily or not.

Sorry i have a (probably) dumb question : what are jsweet's limitations regarding the packages (java packages in the java source code) ?

It seems like I cant transpile any java code if it uses a class that is not in the same package. I re-read the language specifications but I probably missed something ...

EDIT : It works if i put the complete name of the class (with the package). EDIT2 : Even worse, your example with packages (blocksgame) transpiles ...

[renaudpawlak]

No. There are no specific limitations regarding to packages at compile time. What you describe is either a bug or a misunderstanding.

On the other hand, what you describe seems related to a typical problem at runtime with JavaScript. Typically, if you refer to a class that has not been yet declared, it will fail.

Maybe you could give us more information on what you are trying to do here?

Given the two following classes

package jsweet.client;
import jsweet.client.util.Toto;
public class Portfolio {
    public static void main(String[] args) {
        Toto toto = new Toto();
    }
}

package jsweet.client.util;
public class Toto {
}

I get the following error when building :

Oh ... I think I found, that's because my package name is beginning with "jsweet." , isn't it ?

[renaudpawlak]

YES! I was writing a response when I got your answer!!! The jsweet package is not allowed but does not raise any error (that would be a good enhancement). Please don't use jsweet as a package name. Also, watch out Globals classes, they have a special meaning. I'll create an issue.

[gege-fr]

I'll change the package of my generated swagger client : it was jsweet.client ... ;-)

[renaudpawlak]

see #113 thanks!

[gege-fr]

update :

• switched to promises instead of legacy callbacks
• added param to add custom headers to request

incoming :

• simpler example with only two modules with a small trick in backend sources (a small main class that starts jetty and dumps the swagger def file by itself) ; that trick could become a small maven plugin.

[gege-fr]

Done. Now sample project is tad simpler. Feedback will be welcomed ! :-)
