[Dsg-hallc_epics] Tomcat webserver for development - WebOPI

[Tyler Lemon]

Hi Wesley, 

We're still in the planning phase of the Hall C EPICS project so we want to gather information on what needs to be done and start a discussion on the best way to implement it. 

You mentioned in your CCPR reply that there are security implications that we would have to deal with when setting up WebOPI. Since we will most likely have to deal with that, regardless of whether we set up WebOPI, wedm, or something else, can you elaborate some on what the security implications are? 

Wedm and WebOPI look to be pretty much the same thing. Both are applications run on a tomcat server that make their respective file types available through a web browser. Doesn't wedm have the same security risks as WebOPI? Is wedm recommended just because accelerator developed it? 

If there are concerns about WebOPI's support, it seems there should be the same concerns about EDM since that is the previous generation of EPICS GUI software. I cannot find a working link to get the files to install EDM. 

Using wedm also forces one of two situations: 1. having to do double work to replicate CSS screens in EDM, 2. using only EDM and having a monitoring interface built on last generation software. 

With WebOPI, we'd at least be able to use CSS for all aspects of the controls system, increase the length of time it'll be usable and have support, and be ready for the next OPI-to-web interface. 

Best regards, 
Tyler

Tyler, 




As Steve touched on from our discussion, we (Hall B) are going to establish a subset of PVs that need this functionality and post on epicsweb. I don't intend to recreate the entire tree, that wasn't the long-term plan of hallbopi anyway.

Tyler: 

I think we should fall back to designing EDM screens and putting them on 
https://epicsweb.jlab.org/ . I have a directory 
/cs/opshome/edm/hlc/spectrometers/ where you can dump edl files and they 
see how they look through epics web. For example: 

https://epicsweb.jlab.org/wedm/screen?edl=/cs/opshome/edm/hlc/spectrometers/vacuum.edl
