Exception report when trying dbtest/

(1/1)

fbnts:
Hi,

I have installed Java, TomCat and followed the installation guide.

However, when I goto the dbtest directory I get:


--- Quote ---type Exception report

message

If I hit refresh I occasionally also get:

Also, if I just goto the queuemetrics path I get:

--- Quote ---HTTP Status 404 - /queuemetrics/qm_start.do
--- End quote ---

The only stop I could not complete was:
7. Edit WEB-INF/web.xml, change the parameters of JDBC_URL to reflect your installation. The included version uses a database called queuemetrics  that is on a the same server, using a user called “queuemetrics” which password is “javadude”.

I could not find any reference to JDBC_URL.

Is this error related to this missing step?  Also, what do I need to put in my web.xml file?

QueueMetrics:
Really strange - looks like the webapp is in a wrong state and is not recognizing its internal components. Try to reinstall the original web.xml, if that is damaged the whole webapp is ignored.
Or maybe did you install it as a subdirectoty of an existing webapp?
