Can we use the dsp to retrieve data of the user from external databases through Integration Server’s jdbc adapters ? Basically can we perfrom CRUD?
Can we use the dsp to session manage?
Lastly, If I use Javascript in my web application, for example i have a button and i want to display certain fucntionality after i click the button or retrieve some data, so can i invoke dsp flow services in that?
Conceptually the built-in web server of IS is similar to Ruby on Rails, in that you can deliver server-side processed pages.
To get started, I recommend that you look at the pages in the WmRoot package. Using these as a starting point is what I did many years ago.
In addition, there is no problem to also use things like JQuery, Bootstrap, or even Angular. But for starters I would probably recommend to start with just Bootstrap, Tailwind, or whatever you like. And then, as always, it just depends on the requirements.
for further informations you should look for the DSP and Templates Developers Guide as well as the IS Built-In-Services Reference available in the documentation section.
Don’t be limited to DSP to handle your UI. You can still build your UIs with JS librairies like jquery, react or angular. With JS librairies you can consume apis built by webMethods. So don’t be limited by DSPs.
