Any changes in Java HTTP Box naming in the last couple of months?

[Joel Hughes]

Can anyone recall changes to Java HTTPBox naming in the past couple of months?

Scanned the commit logs, but nothing jumped out. 

Upgrading/Updating an app last deployed in September with the last foam and getting the following on my requests to java running on Google App Engine.

{"class":"foam.box.Message","attributes":{},"object":{"class":"foam.box.NoSuchNameException","name":""}}

Request:

1. {class: "foam.box.Message", attributes: {replyBox: {class: "foam.box.HTTPReplyBox"}},…}
1. attributes:{replyBox: {class: "foam.box.HTTPReplyBox"}}
2. class:"foam.box.Message"
3. object:{class: "foam.box.SubBoxMessage", name: "Configuration", attributes: {},…}
1. attributes:{}
2. class:"foam.box.SubBoxMessage"
3. name:"Configuration"
4. object:{class: "foam.box.RPCMessage", name: "select_", args: [null, null, 0, 9007199254740991, null, null],…}

This example is on a package/class: com.serviceecho.workorder.schedule.Configuration

Assuming I need some additional configuration. 

Thanks for any info.

Can you point me to a java servlet example so I can verify against my implemenetation?

Thanks

Hi Adam

So my servlet is modelled after origintrials.servlets.APIServlet, is this style still supported?

I've been using this particular Servlet for probably close to a year now, something in the underlying box/registry in last couple of months has changed.  I'm ok with refactoring as you do, but I've got nothing to go on. 

Thanks for any ideas.

The payload you posted has a subbox messages named 'Configuration' inside an additional subbox message also named 'Configuration' but I doubt that matches the server configuration.

I would investigate why it's being decorated twice.

I'm away from my computer at the moment so I can't point you to any examples but will try to do so later.

Most of our modern box stuff is in foam/nanos, but nanos doesn't currently use a box registry.

LocalBoxRegistry failing with ClassNotFoundException on what I believe is this cast to 'Registration'. 

I can't find reference to Registration elsewhere so suspect something was removed/changed and this was missed. 

LocalBoxRegistry.doLookup

      javaCode: `

Object registration = getRegistry_().get(name);

if ( registration == null ) {

  throw new RuntimeException("No such name");

}

return ((Registration)registration).getExportBox();

`

    },

In my call LocalBoxRegistry.register I'm not requesting anything name Registration, hence I believe it's the cast above.  The stack trace doesn't line exactly with the  `` code blocks.

Yes it does.

Does your generated LocalBoxRegistry.java contain the Registration inner class?

public static class Registration extends foam.core.AbstractFObject {

Hi Adam

Registration is now found. 

Thanks

So now back to the original issue. I'll provide an update later.

Hmm, I probably can't use the context to create an inner class like
that.  Can you pull and try again when you get a chance?

[Joel Hughes]

Found it.  I have a local modification to DatastoreDAO to support long strings - store String as type Text.  I hadn't committed the change to my fork and it got lost when I was updating everything recently. 

There was a short discussion about this on forum about a year ago, but nothing came of it, as we are all a little too busy.  

So I'm back running on the lastest FOAM against GAE. 

Thanks

What was the original issue?
