Resolving problems with web application

Hi,


There is an application that our team uses that has been throwing "Connection Time Out" errors very often.
We want to resolve this problem ASAP, but we are at a dead end of how to go about resolving this problem.


The application that we use is apache-tomcat-6.0.32. In the same server that this version of tomcat runs, we also have applications running on apache-tomcat-7.0.12.
For the latter, there is no connection time out problems. After further investigation, I found an article that says :


Quote:
Support for Apache Tomcat 6.0.x ended on 31st December 2016. There have been multiple security vulnerabilities announced since then that are very likely to affect the 6.0.x series (once a Tomcat version reaches EOL, it is not assessed to see if it is affected by new security vulnerability reports).
So I believe that this is the cause for the problem ?


To resolve this our team has discussed, and the plan is to upgrade the tomcat to tomcat 8, and josso from 1.8 to josso 2. I have started the setup and config of josso2, however now I am stuck at getting the user credentials from our database.
I am sure this will take some time to resolve, although I cannot estimate how long.


Is there a way to temporarily stop the "Connection Time Out" problem? Is it possible to add some values/variables in workers.properties or any other config file in tomcat to resolve this problem temporarily?

verifier(1M)						    Application Server Utility						      verifier(1M)

NAME
verifier - validates the J2EE Deployment Descriptors against application server DTDs SYNOPSIS
verifier [-v] [-d destination_directory] [-r [a|w|f]] jar_filename Use the verifier utility to validate the J2EE deployment descriptors and the Sun ONE Application Server specific deployment descriptors. If the application is not J2EE compliant, an error message is printed. When you run the verifier utility, two results files are created in XML and TXT format. The location where the files are created can be configured using the -d option. The directory specified as the destination directory for result files should exist. If no directory is specified, the result files are created in the current directory. Result files are named as jar_filename_verified.xml and jar_filename_ver- ified.txt The XML file has various sections that are dynamically generated depending on what kind of application or module is being verified. The root tag is static-verification which may contain the tags application, ejb, web, appclient, connector, other, error and failure-count. The tags are self explanatory and are present depending on the type of module being verified. For example, an EAR file containing a web and EJB module will contain the tags application, ejb, web, other, and failure-count. If the verifier ran successfully, a result code of 0 is returned. A non-zero error code is returned if the verifier failed to run. OPTIONS
-v verbose debugging is turned on. -d identifies where the result files get placed. -r identifies the reporting level defined as one of the following: o a sets output reporting level to display all results (default) o w sets output reporting level to display warning and failure results o f sets output reporting level to display only failure results jar_filename name of the ear/war/jar file to perform static verification on. The results of verification are placed in two files jar_filename_verified.xml and jar_filename_verified.txt in the destination directory. Example 1: Using verifier in the Verbose Mode example% verifier -v -d /verifier-results -rf sample.ear Where -v runs the verifier in verbose mode, -d specifies the destination directory, and -rf displays only the failures. The results are stored in /verifier-results/sample.ear_verified.xml and /verifier-results/sample.ear_verified.txt. asadmin(1M) Sun Java System Application Server March 2004 verifier(1M)
