So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.

There's only one problem: You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.

or "Bonus Breakage"

In our last lesson, we added a relationship between 2 persistent classes. We are clearly going to need to start creating REST Services to expose CRUD operations for each of these classes, but before we do that, we should really finish defining our linkages. We added code to our Widget toJSON to spool off related Accessory data, so we should really do the reciprocal and allow Accessories to return all Widgets that are compatible.

This series of articles aims to address the following topics:

• Creation of a web application based on REST pages;
• Overview of some tools for tracing (debugging) HTTP requests;
• Switching from hyperevents to... hyperevents;
• Integration with jQuery File Upload;
• Conversion of JSON from the {id:1,parentId:1} format to the {id:1,children:[{}]} format for tree visualization;
• Integration with jQuery EasyUI (using datagrid and tree as examples);
• Other topics.

Hello Community,

I recently encountered a issue with Caché and I can't figure out where the problem is coming from.

I noticed that the license limit (200) was reached whenever I was opening my Studio (so it seems). When this occurs, I restart Caché (with the Cube in the Taskbar), and the number of license used is back to 1%, but grows back after. The time taken before the number of license grows back again looks pretty random.

Here is a couple of screenshots :

Hi, Community!

Hello, evrybody, I'm writing one project using CSP("OnPreHTTP"), and also REST angular. At the beginning I wrote purely on csp, then I decided to use angular for the flexibility of the client part. Now I can not design logging, I created a table App.Log with properties

Sometimes you can face the situation when you did update the web app on Caché server but you cannot get the newest version of the app in a browser.

Here are couple recipes which help me to solve it. From simplest to more sophisticated and not obvious.

1. Refresh page in a browser

In Chrome it is Ctrl+R or 'Refresh' button. Obvious, but helpful.

2. Hard reset in a browser

If you are in Chrome, open Developer tools

If the session is in inactive state for some time. It should be logging out automatically. Is there any settings for that??

Hi everyone! My company has a Zen ERP application with CSP delegated authentication. Now, we're developing a separated BI application, using Angular, which consumes DeepSee REST API services. Both applications access the same Caché database.

How to implement single sign-on strategy in order to allow an already authenticated ERP user to access DeepSee REST services? Has anyone already implemented something like that?

Thanks in advanced.

Hi All,

I need some clarification on web service (Soap Service). For each Soap request, system consuming 1 license and it is not releasing until CSP session timeout and extra grace period 5.10 minutes(310 seconds).
Due to this, at some time license consumption is full.
If i use with Login credential (i.e password authenticated web service), it consumes one license for 25 connections(request).
But i need to use it as anonymous user(Unauthenticated).
Please advice.

Thanks,
Sabarinathan M

Hi all-

We used to have this Java applet in our CSP page to "print all" and "download all" PDF medical reports. We want this applet so that the user won't have to open each PDF in the browser just to print it.

But now most browsers do not support Java applets anymore due to security concerns, so that Java application is down. We tried to migrate to Java Web Start but don't know how to invoke the JNLP file from the CSP page. I am new to Cache so any help would be greatly appreciated.

I'm looking at adding multilingual support to a couple of open source projects I'm working on. The solutions are already developed in CSP so I am not looking for alternative approaches.

I'm wondering what would be the best approach for CSP and separate JavaScript files.

Initially I was wondering if I should bake the default system language text at compile time, or provide the end user with a language selection option at run time.

I came across $$$TEXT reading the docs...

Hello All,

While extracting the huge amount of data in the cache through the Zen page, file extraction timing is greater than session time out. How to increase the session timing in Zen/CSP gateway or If any other solution would be appreciated. Please advise.

Hi,

I'm trying to use WebSocket for my application. I am trying to get the example in this link (http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...) to work. However, I keep getting the error "CSP application closed the connection before sending a complete response". Does anyone know why?
