Re: [jetty-users] Jetty 9.4.7 to 9.4.11

Hi

It's probably better to use the embedded xml stream parser with the jvm.

The Apache jsp compiler [1] is using xml stream parser so if you force a factory this must available in the classpath. (see details here [2])

We deploy via context xml files in a directory external to both jetty and jetty.base

It turns out that removing those global system properties has fixed both the issues, so, woohoo.

How are you deploying your apps, with the distro or embedded?  Can you please enable server.dumpAfterStart=true (in server.ini), and report the output?

thanks

Ah, the WstxInputFactory is because of some system properties we were crudely using.

-Djavax.xml.stream.XMLEventFactory=com.ctc.wstx.stax.WstxEventFactory
-Djavax.xml.stream.XMLInputFactory=com.ctc.wstx.stax.WstxInputFactory
-Djavax.xml.stream.XMLOutputFactory=com.ctc.wstx.stax.WstxOutputFactory

I guess jetty now using javax.xml.stream and so was broken by that.   

Don't think that is why JSP compilation is not working.

Have just attempted to do this upgrade.

Apps all deploy, but am getting the following so no JSP's compile.
