Marking servlet LowayTransactionController as unavailable [RESOLVED]

(1/1)

peisch:
Hi,

I'm trying to get the 1.7.x.y system to 13.x.  The yum update worked fine and my system now has:

queuemetrics-13.12.4-700
queuemetrics-tomcat-6.0.33-20
queuemetrics-java-1.6.0_22-21

The update also copied over the WEB-INF/web.xml and my mysql path is correct and the license key is preserved.  Catalina log entries look fine except for this:


--- Code: ---INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /usr/local/queuemetrics/jdk1.6.0_22/jre/lib/i386/server:/usr/local/queuemetrics/jdk1.6.0_22/jre/lib/i386:/usr/local/queuemetrics/jdk1.6.0_22/jre/../lib/i386:/usr/java/packages/lib/i386:/lib:/usr/lib

--- End code ---

The localhost log shows me this:

i'm guessing that this isn't really going to work because request via http get me this:


--- Code: ---HTTP Status 404 - /queuemetrics/

type Status report

message /queuemetrics/

description The requested resource (/queuemetrics/) is not available.

Apache Tomcat/6.0.33
--- End code ---

What did I do wrong?  How can I either debug the issue or get the servlet to load?

Thanks!

We're following this request in our mail support :)
I'll update this thread as soon as we find a solution.

Found the answer to this.  There's a lingering queuemetrics.xml file that persists after the update.  Removing it resolved the issue.


--- Code: ---[root@tarn-test ~]# cd /usr/local/queuemetrics/
[root@tarn-test queuemetrics]# find . | grep queuemetrics.xml
./tomcat/conf/Catalina/localhost/queuemetrics.xml
[root@tarn-test queuemetrics]# cat tomcat/conf/Catalina/localhost/queuemetrics.xml
<?xml version='1.0' encoding='utf-8'?>
<Context docBase="/usr/local/queuemetrics/webapps/queuemetrics-1.7.1.6" path="/queuemetrics">
</Context>
[root@tarn-test queuemetrics]# rm tomcat/conf/Catalina/localhost/queuemetrics.xml
rm: remove regular file `tomcat/conf/Catalina/localhost/queuemetrics.xml'? y
[root@tarn-test queuemetrics]# /etc/init.d/queuemetrics start
