Deploying Tapestry applications into Glassfish has one snag: a conflict in the StAX parser (used to parse component templates). Tapestry must use the Woodstox StAX parser, and Glassfish provides an alternate parser.
Fortunately, you can override Glassfish, and force it to use Woodstox as its default StAX parser.
First, copy and Woodstox and its dependencies into the Glassfish domain's lib/ext directory; these files are:
It is no longer necessary to include these files in a Tapestry WAR, though it doesn't cause problems if they are left in.
Second, use Glassfish's console to configure some system properties:
| javax.xml.stream.XMLEventFactory | com.ctc.wstx.stax.WstxEventFactory |
| javax.xml.stream.XMLInputFactory | com.ctc.wstx.stax.WstxInputFactory |
| javax.xml.stream.XMLOutputFactory | com.ctc.wstx.stax.WstxOutputFactory |
You will be prompted to restart Glassfish. Tapestry applications will now deploy properly.
