Metro+Jetty+Jsonwebservice issues

[minami]

Hi.

I've tried to implement simple standalone application that exposes same api via json-rpc and soap. Please find sources attached, they are ultimately simple.

So, SOAP works smoothly, but json-rpc is not.

Here is two problems I'm stuck on:

1) When I'm calling http://localhost:8080/web/json?js , I'm obtaining the following stacktrace:

16:04:02.130 [pool-1-thread-3 - /web/json?js] DEBUG org.eclipse.jetty.server.Server - REQUEST /web/json on AsyncHttpConnection@2d69b054,g=HttpGenerator{s=0,h=-1,b=-1,c=-1},p=HttpParser{s=-5,l=9,c=0},r=1

2) When I'm trying to call method, I'm obtaining the following stacktrace:

It's interesting that pretty GUI at http://localhost:8080/web/json? works and addresses like ?config , ?jsonmodel works too.

Could anybody help me to resolve these issues please?

I've fixed the second issue with patch attached.

Could you review it and apply to sources or make something similar?

[Sundar Murthi]

Hi Minami,
Thanks for the patch. I will get back to you very soon with this update.

For first issue js client generation, Which json client your trying to use? (Jquery, yahoo ui or other)

Which json client your trying to use? (Jquery, yahoo ui or other)

I'm just trying to get this URL via browser.

Also I've found that if I open the following URL: http://localhost:8080/web/json?formsayHi , then click "Submit", the same stacktrace is generated.

[minami]

1) When I'm calling http://localhost:8080/web/json?js , I'm obtaining the following stacktrace:

Any URL like this: http://localhost:8080/web/json?sayHi.arg0=xxx , xxx may be empty causes stacktrace.

Hi,

   Fix for second issue is in our svn, will be included in next release.

For first issue (java.lang.StackOverflowError) from meta data producer. I am trying to reproduce it, but I can't reproduce it.   Can you give more information on,

1) Java version?

2) Metro(jax-ws) version your using?

You simply try doing post insteed of get. You can do it quickly in end point document by pressing ">>" button.

Copied from your pom.xml into my pom.xml

There is NO problem with method calls, they are works.

But ?js service URL and your debug urls like ?sayHi.arg0=xxx are producing stack overflow.

[Sundar Murthi]

Thanks Again,

    Indeed this is an issue with metro 2.1 and json codec.

Codec was tested with 2.0.1.

There is implementation change in metro, which always looping the get request.  This is fixed in codec.  Fix included in next release.

In 2.1.0

public void invokeAsync(WSHTTPConnection con, CompletionCallback callback) throws IOException

/*     */   {

/* 465 */     if (handleGet(con)) {

/* 466 */       callback.onCompletion();

/* 467 */       return;

/*     */     }

/*     */ 

/* 469 */     Pool currentPool = ge

// In 2.0.1

 public void invokeAsync(WSHTTPConnection con) throws IOException {

/* 401 */     Pool currentPool = getPool();

/* 402 */     HttpToolkit tk = (HttpToolkit)currentPool.take();

/*     */     Packet request;

/*     */     try {

/* 405 */       request = decodePacket(con, tk.codec);

/*     */     } catch (ExceptionHasMessage e) {

/* 407 */       LOGGER.log(Level.SEVERE, e.getMessage(), e);

[minami]

Ok, so may I donate some $$ for your perfect work? :3

[minami]

And just one more question. Could you upload your pretty codec into maven central? Or, at least, setup your own repository?

[Sundar Murthi]

In central maven may available end of this week or latter. We are in progress of adding in central public maven repository.

Mean time you can download the 0.8 version and add it in your local repository.

[jsonwebservice]

Finally
   We have public maven repository for json plugin.

Here is the location.
