GWT Console login problem

[kukeltje]

Ok, I admit it... I am learning GWT (a little) to investigate a certain forms technology. So I checked out the source and followed these steps:

- cd gwt-console
- mvn install
- cd ../jbpm4
- mvn -Pdistro clean install

and ran the jbpm installer on a clean JBoss AS 5.0

When I tried to login, I got the following exception in the Firebug console:

[Exception... "'java.lang.RuntimeException: Unknown error upon login attempt' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]

No errors in the AS log or whatever.

When I want to debug the application using

[kukel@laptop war]$ mvn com.totsp.gwt:maven-googlewebtoolkit2-plugin:gwt

All I get is

Warning: JAVA_HOME environment variable is not set.

when I try to login.

The application does not even respond anymore in this situation

So does anybody have any idea how to 'fix' this?

[heiko.braun]

I guess you are experiencing two different problems:

a) One related to the actual app
b) another related to the build, setup, etc when testing the GWT console.

We would need to regard them separately.

My question for now:

a) What firefox version are you using?
b) any errors in the GWT shell (hosted mode, not the actual linux terminal)

[kukeltje]

I was just going to provide some additional info, mainly regarding b), but to answer in order:

a) FF 3.0.8 with Firebug 1.3.3 (will try without firebug tonight)
b) Initially none, but patient as I am, I left it open and after 5 minutes of 100% cpu (one cpu lucky I have two :-) so I did not notice it) this error occured:

Oh, and after this, I do see the console, but nothing realy responds if requests have to be made to the server.

[heiko.braun]

Yes, the current error handling is bad. It sometimes leaves the console in a weird state. More of problem is that the error messages are not very self explaining. But from what you describe, you seem to be running into a timeout in situation b)

[kukeltje]

Running the same installer and deploying to JBoss AS 4.2.2 I get the more detail about the error in FF:

[Exception... "'java.lang.RuntimeException: Unknown error upon login attempt' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c (NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]
getElementsByClassName("title", "span", undefined)menu.js (line 123)
init()menu.js (line 42)
[Break on this error] var arrElements = (strTagName == "*"...: oElm.getElementsByTagName(strTagName);

I'll try to find out some more, but I'm just curious if I'm the only one experiencing this with the latest from trunk...

[kukeltje]

I found the 'problem'. I initially had the same issue (but different errors) with the new gwt-mosaic version. By accident I looked in the Firefox errors console and there was an error report about "code from 127.0.0.1 accessing something probably not accessing localhost". So I tried changing 127.0.0.1 in my browser to localhost and it worked. Makes me wonder where this comes from and whether it will be a problem if there is a revers proxy in front of the jBPM console (which in many cases there will)

[heiko.braun]

Can you provide some stacktraces? Did the new console show any errors, or did you have to pull it from the ff err console?

[heiko.braun]

"code from 127.0.0.1 accessing something probably not accessing localhost"

is this your interpretation, or the exact wording? I would need something more specific to investigate.

[kukeltje]

The Firebug console showed a realy huge error, the standalone GWT 'console' version worked fine.

The FF console error (different than the one in the Firebug console) is my wordings. I can test tonight again and provide you with the full errors.
