I have implemented a Single Page Application getting information from WO REST generic services.
The Single Page Application is using also the Direct To Web rules from WO. This idea would be to be able to have a full Javascript interface on top of your existing business logic and D2W rules. The only problem is that you loose the EOF transaction mechanism when saving with web services. Anyway, if you are interested, I have a GitHub project. It is far from finished (a lot of D2W components are missing) but you can have a look if you want: https://github.com/domschoen/d2spa For serving WO REST services and rules, this WO Application has to be running also: https://github.com/domschoen/D2SPAServer SPA application communicate with WO app through web socket.

It’s been a little while since I looked at moving to Cayenne, so this is good information. I think I might try going the annotations route or settle on interfaces, as Hugi suggested (I already do something like that, however it is driven from the EOModel userInfo when generating my parent _EOEntity classes). In any case, it is good to know that the foundations for metadata support is there if needed.

There is a generic extension mechanism that allows any tool (CayenneModeler, class generator, etc.) to embed and read stuff in the project XML that is not a part of the main schema, that can be associated with specific model objects. Some examples where we use it internally: 1. Cayenne 4.1 (that just went beta the other day) allows to embed "dbImport" tool information in XML. It is used to keep your model in sync with incremental DB changes. 2. (Perhaps more relevant) 4.1 also has a "comment" field for every object, editable in the Modeler, that generates <info:property> tags in an alternative namespace. E.g.: <obj-entity name="Artist" className="org.apache.cayenne.testdo.testmap.Artist" dbEntityName="ARTIST"> <obj-attribute name="dateOfBirth" type="java.util.Date" db-attribute-path="DATE_OF_BIRTH"> <info:property xmlns:info="http://cayenne.apache.org/schema/10/info<https://eur02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcayenne.apache.org%2Fschema%2F10%2Finfo&data=02%7C01%7Cdominique.schoenenberger%40nagra.com%7Cd22653b2f70a4216c55008d6ad177073%7Ce573309544254f08b6ba487b9a46a425%7C0%7C0%7C636886713530738599&sdata=9mXJkR0lqsq0IsbsBfUh42aI0fr1ha341JA9%2B2WqnSI%3D&reserved=0>" name="comment" value="attribute comment"/> </obj-attribute> <info:property xmlns:info="http://cayenne.apache.org/schema/10/info<https://eur02.safelinks.protection.outlook.com/?url=http%3A%2F%2Fcayenne.apache.org%2Fschema%2F10%2Finfo&data=02%7C01%7Cdominique.schoenenberger%40nagra.com%7Cd22653b2f70a4216c55008d6ad177073%7Ce573309544254f08b6ba487b9a46a425%7C0%7C0%7C636886713530748613&sdata=RGrINs0B%2B1EC97Aq%2BH200WDQRjiMw6klHRDQrLFlNy0%3D&reserved=0>" name="comment" value="test comment"/> </obj-entity> 3. Cayenne 4.2 includes class generation settings in the model. So the mechanism to extend project metadata is there. Using it to your own ends is still a bit challenging. The API is somewhat obscure. So my advice would be to look at the alternative designs. But if they prove unsatisfactory, we'd welcome a discussion about further extensions on Cayenne dev@ list. We are almost there and if someone makes this feature a priority, there's a straightforward road to implementing it.

I’ve been looking at Cayenne as a replacement for EOF and one roadblock I am running into at the moment is support for a userInfo type structure in the Cayenne datamap. Admittedly, it’s been about 6 months or so since I’ve looked, but from what I could tell, this appeared to be an open issue with Cayenne. It looked like there might be some idea on how to implement it at one point, but I did not see any resolution or implementation of it. I make extensive use of the EOModel userInfo dictionary (primarily on entities, but also on properties) to identify things that are configured at runtime. For example, I have a key named “taggable” that drives the template generation of my _EOEntity.java files. I also use userInfo entries to specify information for my auditing framework (e.g. being able to specify whether or an entity is audited, which keys to audit, etc.) or my custom filtering framework (e.g. to be able to turn on custom searches for an entity and to identify the keys that can be used in custom searches). These are just a few examples. My current thinking is to separate this metadata from the model and move it into its own configuration file, but that opens up the risk of the metadata getting out of sync with the model. It also seems a little dirty to me. Curious if anyone else is in a similar position, or has already solved such an issue?

Had parallel branches for a while and then switched in production, never looked back. Cayenne is similar enough that most of the work is either boilerplate conversion or actually making use of the newly-gained benefits. Very few hard problems encountered, and all solved. Let's have a talk in Frankfurt about what your EOF specifics actually are.

In preparation for the coming WODay in Frankfurt, I'd love it if you'd be open to having a discussion on the status and future of WO, so we can enter the coming work prepared. I'd like to begin by sharing my own thoughts on the matter, based on my current stack and experience. It's a rehash of something I posted to our Slack yesterday, may sound revolutionary and will no doubt be controversial, but I think some outside-the-box thinking is required at this time. This is lengthy, sorry about that… -- In the past few years I've been working towards minimising the use and effect of WO/Wonder on my stack, so when and if The Time comes, I and my customers have a migration path forward. Among the things I've done is move from EOF to Cayenne and from Ant to Maven (to make using 3rd party jars, including Cayenne easier), both of which have turned out to have been very happy decisions which I wholeheartedly recommend, regardless of anything else you do. I love working with my WO/Cayenne stack, which is currently only "polluted" by the following frameworks: -- WO: * JavaFoundation (indirectly through WO, I never use foundation classes in my code unless absolutely required by WO) * JavaWebObjects -- Wonder (I consider Wonder "polluted" since it depends on WO/EOF) * ERExtensions (only the WO stuff, not the EOF stuff) • Ajax • WOOgnl (indirectly for parsing Wonder-style inline templates) …and of course then there's the deployment stuff (JavaMonitor,wotaskd, adaptors). Given this, here's my proposal for a way forward: * We abandon EOF (and, in fact, any ORM—this is not meant to be a full stack effort, initially at least) * We re-implement JavaWebObjects as required (and the absolutely necessary parts of JavaFoundation, such as KVC and NSBundle) as a single framework * We separate the necessary WO stuff from the EOF/D2W stuff in Wonder (as well as other totally unrelated things like mail sending frameworks, other utility frameworks and "useful applications") and include it in our re-implementation * We create a fork of WOLips that knows how to live within the New Universe * We rule the world Ideally, what we end with is Just a Web Framework™ with IDE integration (and nothing else) that can serve as a basis for future development. While re-implementing WO may sound like a huge undertaking, I actually think it's smaller than rewriting all of my solutions that depend on it. This probably applies to more of you. Now, looking at my own stack I know this proposal might sound a bit self-serving, but I'd like to hear other opinions. I believe it's a realistic way forward with (comparatively) minimal development effort. Turns out that WOF itself is the only part of the WO/Wonder stack that I really just don't want to live without. This is something I'd like to do, and if anyone likes the idea and is willing to participate, I'm confident we can make this work! Doing stuff alone sucks.
