Failed to connect to spawned VM!

[Stefan Lecho]

We've integrated v1.0.1 of DJNativeSwing in our project. On some client
machines we're having an "Failed to connect to spawned VM!" exception. It is
not really clear why this error is generated on certain machines and not on
others.

-Would it be possible to get more information about the real cause of this exception ?
-How can we generate detailed logging for the DJNativeSwing component ?
-Does DJNativeSwing depends on certain OS settings to be able to work correctly ?

Hi,

Would it be possible to get more information about the real cause of this
exception ?

Use the 1.0.2 preview version. I improved this troubleshooting a while ago.

How can we generate detailed logging for the DJNativeSwing component ?

The is no particular logging interface. Lots of system properties can be
activated but they generally dump the information to the console.

Does DJNativeSwing depends on certain OS settings to be able to work
correctly ?

For certain browser runtimes to work there may be tweaks to paths on certain
platforms, but generally the default case should just work.

Hope this helps,
-Christopher

Use the 1.0.2 preview version

-Is the 1.0.2 preview version "stable" enough to be used in a production environment ?
-When do you plan to release an official 1.0.2 version ?

[Christopher Deckers]

1.0.2 only contains bug fixes. I don't have any particular features to add.

I have no plans to release 1.0.2 because it does not contain any features, and
does not contain any critical bug fixes... Of course, if after a very long
time there is no particular addition to 1.0.2, then I might release it.

In other words, yes, as of now it should be stable, more stable than 1.0.2
because of potential bug fixes.

hope this helps,
-Christopher
