Clojurians Log v2

I'm using the hoplon-castra template to walk through the tutorial on castra, but I am trying to connect to a localhost oracle xe database. I was able to do this in lein by installing the ojdbc jar to my maven repo and including a dep like [local/ojdbc "12.x.x.x"]. Boot can't seem to find the ojdbc jar.

What do I have to do to make boot aware of the jar in my maven repo?

@nuclear_tech_support add it to your dependencies

@flyboarder I added [local/ojdbc8 "12.2.0.1"] to my :dependecies in build.boot, but boot doesn't seem to find it on my class path.

is that the correct group?

looks weird

Well, I installed Oracles ojdbc.jar in my maven repo, and that is how I add it using lein.

try without local/

Could not find artifact ojdbc8:ojdbc8:jar:12.2.0.1 in clojars (https://repo.clojars.org/)

Could you post your dependencies vector? Also what is the path you have the package installed at?

That would suggest it cannot be found in the local repo so it is looking at clojars

:dependencies '[[adzerk/boot-cljs          "1.7.228-2"]

                  [ojdbc8 "12.2.0.1"]]

C:\Users\xb0g\.m2\repository\org\oracle\ojdbc8\12.2.0.1

oh then try this org.oracle/ojdbc8

actually, I found the jar file here: C:\Users\xb0g\.m2\repository\com\oracle\ojdbc8\12.2.0.1``

ok so try com.oracle/ojdbc8

That seems to have got it, but I still can't seem to get data from the database to the page. I just get "Server Error" as the error message. Is there a way I can see what's going on in the castra server?

@nuclear_tech_support some well placed prn’s should do it 😉

You should also be able to extract the error from the javelin cell, but I dont use castra myself

So... What do you use for your server?

node

Is there an example of using hoplon with regular REST calls?

Hoplon is unrelated to the transport system

you can use anything

I myself use websockets

via feathersJS

Since Hoplon uses jquery by default you could use that for your rest calls

Okay, so I can just set up some storage cells, use those in some calculation cells, and deref those in my UI. Then fire off some jquery getJson and give them a callback that mutates the storage cell.

right?

bingo

Thanks.

np

@nuclear_tech_support once you figure out how that process works, everything in hoplon gets easier
