Any idea what could be wrong ? Thanks in advance.

[bloch]

this is a conflict with the jing.jar that laszlo requires and theone that comes with resin.

I believe there are other reports here.

Copy the laszlo jing jar into resin.

[Jelan]

Resin does not provide a jing.jar however it comes with isorelax.jar which might be the issue, i dont know how to solve it thought.

[bloch]

3.0.7 had a jing.jar

it there's no jing jar, it's likely the caucho folks bundled the com.thaiopensource classes in some other jar. You'd need to remove/replace those with the laszlo versions.
