Error on JettyLogger?

[MagusDrk]

Hi everybody. Just two days ago, My GWT app suddenly stop compiling
after I applied an update. Now, I'm not being able to figure out what
is the cause and even less how to solve it and make my app run again.
I'm completly disoriented on how to get it work, I've thought there is
an error on the updated plugin (Google Plugin for Eclipse) or that
something is corrupt on my GWT SDK installation.

I hope somebody can help me, because to make my app to run again is my
priority.

When I use Google > GWT Compile there is no wanrning at all. (Just a
"Ignored 1 unit with compilation errors in first pass.", but it have
being present before app stop running)

When I Run or Debug my app, It lloks like the app is well compiled,
but in console I find the below stack.

After it, the Development Console shows me the url to run my app:
"http://127.0.0.1:8888/MyApp.html?gwt.codesvr=127.0.0.1:9997"

But when i open the url, page says service is unavailable (below, next
to console stack)


All help, someone can give me, is absolutely welcome. I've searched
for all the web with no sucess. I hope a quick response.

Thansk a lot.

Sounds a bit like multiple gwt-Jars loaded by different ClassLoaders.

Hi Lothar.

Thanks a lot by your suggestion. Actually, my project had several jars
and it's probably a couple of them were being on conflict or something
like that. I've just removed all my jars and re-added only the needed
ones. My app run again with some css/skin diferences (I don't know why
yet) but it is finally running.

May be after the last update some jars where updated with conflict
wich generates the issue. After removing all those "unnedded" jars, I
suppose I'll get some error on excecution time, etc. but I've solved
them before (I guess).

So, the solution was remove all jars and use a clean version of only
needed jars.

I am very grateful, Lothar. some related issue I'll be asking.
