> I was > told by the project manager that Apache, Java, and Tomcat were "showing > signs of age." -- Taking this statement at face value, and taking it to its logical end (that you'll have to migrate your application), I'm extremely doubtful that Apache, Java, and Tomcat are so near their ends of life that you must redo your app in less than 8 weeks time or risk technological obsolescence. Far, far from it. "Showing signs of age" is just saying their old (both Apache and Tomcat had support releases in April), not that they don't work or fit your precise needs. In any event, if the timeline is real, then something's not right with the reason for changing everything over to "something else" or the person pushing this or.... It's a little mind-boggling. But, to make this a little more constructive, and assuming the 8 week deadline is real, I might consider something like MarkLogic given what you've outlined thus far [1]. That might allow you to preserve your XQuery/XSLT (providing that you have some since you are using eXist) and it gets you a replacement for Solr. Being an XML database and application server, it is designed for XML documents. Unfortunately, it is closed-source, but the company offers a "free" license option that might work for you. If you are investigating something with PHP, Python, or Ruby, I would look at the Zorba XQuery processor [2], which has bindings for those three languages (and a few more) and, being a specific language for manipulating XML documents, should be more conducive to what you need to do with your files. It's pure bonus if you can re-use your XQuery. There also appears to be some support for XSLT 1.0 [3]. I've not done anything with Zorba but install it on a dare.
