Recursive $ref failed

[princehaku]

the sample

{
        "type" : "object",
        "properties" : {
          "child1" : {
                "type" : "string"
            },
          "child2" :{
               "$ref" : "#/properties/child1"
            }
        }
}

it doesn't work

got error There's a problem: URI is not absolute

[princehaku]

private boolean selfReferenceWithoutParentFile(Schema parent, String path) {
    return path.startsWith("#/");
}

line 98 seems return false

@princehaku Are you using the web ui at www.jsonschema2pojo.org or generating this locally? The web UI has a problem with local references (see #183). This is fixed in the current head version, we just need to update the web UI.

[princehaku]

thanks very much .. i'm using your online version run your sample code.
just thought it might be a same problem as below.

generating this locally from the code below depends on jsonschema2pojo-core head version

package com.test;

import java.io.File;
import java.io.IOException;

import com.sun.codemodel.CodeWriter;
import com.sun.codemodel.JCodeModel;

    public static void main(String[] args) throws IOException {
            String source = "{\n" +
                    "    \"type\": \"object\",\n" +
                    "    \"definitions\": \n" +

                    "    }\n" +

Recurisly calling $ref
it failed on URI is not absolute
seems parent node is incorrent

I can see that this issue is kind of old but I'm running in the same problem. Is there a plan to fix it ?

[joelittlejohn]

So it looks like the original example works correctly (the simple case) - that issue was fixed a long time ago. There is a more complicated example here: #250 (comment) and this does not work. This is not a problem with simple recursive refs but a problem with having an inner schema that is referred to by a fragment ref then using another fragment ref to refer outside the inner schema. This only seems to affect the case where there is no parent file (the schema is supplied as a string), and jsonschema2pojo.org is one such place.
