Web Tools Platform (WTP) in 0.6M2


Todd Chambery (461) | asked Sep 04 '07, 3:34 p.m.
Hey all,

I did a clean unpack of the 0,6M2 build and installed the Europa release
of the WST, but when I started up the Work Items view had thrown an
exception.

Is the WTP known to be incompatible?

Thanks,

Todd

I don't know about WTP as a whole but I've installed WST through the
update manager on M2 using the Europa update site without any problems.

Could you provide a stack trace?

Hi Rem,

I checked the Web Tools box (I can't remember the exact name), selecting
all four sub-bits and their required packages. When I clicked the popup
to restart, TeamConcert did not come up. Attached is the stack trace
from the workspace log,

I should mention this is different from the error-ed view I got running
the Jazz client in Linux.

I think in order to get WTP to install/work properly, you need to
download and unzip the whole EMF SDK. TeamConcert ships with a subset of
EMF, not the entire thing, and WTP requires more than our subset provides.

Hope this helps.

Thanks James,

Unfortunately, after unzipping EMF v2.3.0

into my jazz/client, I'm getting a similar set of fatal startup errors.
Log file attached.

A separate install of just the WST also produces the error seen in the log.

For this view error, I recommend that you restart Team Concert with the
'-clean' argument...

../TeamConcert -clean

....or whatever the binary is called. I have seen this problem before. It
occurred to after installing WST and then choosing to restart after the UM
directly. This happened to me on Windows XP. If I chose not to restart,
and to restart it manually with the -clean argument, the problem is fixed.

It is rather odd because I have always been under the assumption that
restarts invoked by the UM would be identical to a -clean...but apparently
not.

Root exception:
java.lang.NoClassDefFoundError: org.apache.log4j.Category
at java.lang.J9VMInternals.verifyImpl(Native Method)
at java.lang.J9VMInternals.verify(J9VMInternals.java:66)
at java.lang.J9VMInternals.initialize(J9VMInternals.java:127)

Could it be possible that you have two log4j bundles and it is causing
problems? I don't know how smart the UM is with regards to this.

Rem

Thanks Rem! -clean appears to have done the trick.

No problem. Glad to help, Todd.

I'm curious as to whether this is a bug or not. It could be an Eclipse
issue though since I'd imagine that users of other Eclipse-based products
must've tried installing other plug-ins through update sites before. But
then when you consider that, surely someone must've reported this bug
before?

Regards,
Rem
