org.apache.jasper.JasperException

[Kristof Stevens]

We installed following fix/patch to improve performance opening huge vessel shipments. :

OTM v5.5 - Updating third party jar files for improved UI performance

Per development these changes only need to be done on the webserver

Shutdown Tomcat and Apache

Download the following
file

http://purl.org/net/flavio/download/standard-1.1.2-patched.jar

It will come down as a .zip file. Do not unzip the file, save the file and rename it at
the same time to standard.jar

Go to the < otm home >/glog/gc3webapp/WEB-INF/lib directory and rename standard.jar to
standard.org

Copy the new standard.jar file to the directory listed above.

Go to the Go to the < otm home >/glog/gc3webapp/WEB-INF/lib/3rdparty directory and
rename standard.jar to standard.org

Copy the new standard.jar file to the directory listed above.

Download the following file:

http://www.ibiblio.org/maven/saxpath/jars/saxpath-1.0-FCS.jar

It will come down as a .zip file. Do not unzip the file, save the file and rename it at
the same time to saxpath.jar


Go to the < otm home >/glog/gc3webapp/WEB-INF/lib/3rdparty directory

Copy the saxpath.jar file to the directory listed above.

Download the following file

http://www.ibiblio.org/maven/jaxen/jars/jaxen-1.0-FCS-full.jar

It will come down as a .zip file. Do not unzip the file, save the file and rename it at
the same time to jaxen-full.jar

Go to the < otm home >/glog/gc3webapp/WEB-INF/lib/3rdparty directory

Copy the jaxen-full.jar file to the directory listed above.

Go back to the < otm home > and set the group, owner and permissions using chmod and chown if needed.

This fix was in Production on HP-UX for months, now we moved to Linux and getting following errormessage
:

Error Exception org.apache.jasper.JasperException: Exception in JSP on Shipmentscreens, Orderscreens etc...And we had to rollback.

As workaround I stopped the webserver, cleaned out /opt/otm/gc3v55_prod1/tomcat/work/Catalina directory and started up the webserver. It solved the issue, but after a couple of minutes, the JasperException is coming back ....

Re: org.apache.jasper.JasperException

Kristof,

Thanks for the updated info! Were these updated jar versions recommended by Oracle? Also - what has the result been? Has the performance of opening large vessel shipments improved? Have you resolved the Jasper errors?

Thanks,
Chris
