Re: [jetty-users] class version problem - use modules?
Yeah, I have the tika-app one, because it's all I see on their download page. I'll search some more for the others you mention.

It appears that Tika comes in two flavors, library JARs and an all-in-on “app” JAR. Which JAR(s) are you using? It should NOT be tika-app because that probably includes a bunch of third-party stuff that is needed to run it as a stand-alone application (such as slf4j). What you probably want is tika-core and/or tika-parsers.

That seems to be a slf4j version mismatch.

 

Be sure that you are using slf4j 1.6.4+

And that you are using the same versions of slf4j on the server and your webapp's WEB-INF/lib.

Hi,

 

I've been blissfully ignorant and simply putting jars into lib/ext or the app's WEB-INF/lib, but today I hit a problem trying to use Apache Tika. If I put the tika jar in lib/ext, Jetty fails to start [1], and I'm wondering if it's because the Tika jar has an older version of an slf4j class. 

 

Is this something I can get around with modules? Maybe I can add the tika jar but keeps its copy of slf4j classes private to itself?  I remember jboss modules doing something like this, but I don't see anything on the doc page [2]

 

thanks,

Rob
