Hi Christopher,
I will try to be as clear as possible. The files that were originally in /usr/local/tomcat/jakarta-tomcat-5.5.17/webapps/MYAPP/WEB-INF/lib were copied by default when I migrated the app to /usr/local/tomcat/apache-tomcat-6.0.53/webapps/ When I ran MYAPP I got the error from my previous email. I then mv all the files from /usr/local/tomcat/apache-tomcat-6.0.53/webapps/MYAPP/WEB-INF/lib into a temp directory , in attempt to make it use the global lib , but still the same error. My next idea was to place the files from /usr/local/tomcat/apache-tomcat-6.0.53/webapps/MYAPP/WEB-INF/lib into /usr/local/tomcat/apache-tomcat-6.0.53/lib , but with the new structure I am unsure what belongs where. FYI : in my original /usr/local/tomcat/jakarta-tomcat-5.5.17/common I have the following directories classes endorsed i18n lib activation.jar antlr-2.7.2.jar axis-ant.jar axis.jar bsf-2.3.0.jar commons-beanutils-1.8.0.jar commons-chain-1.2.jar commons-codec-1.3.jar commons-collections.jar commons-dbcp-1.2.1.jar commons-digester-1.8.jar commons-discovery-0.2.jar commons-fileupload-1.1.1.jar commons-io-1.1.jar commons-lang.jar commons-logging-1.0.4.jar commons-pool-1.2.jar commons-validator-1.3.1.jar edtftpj.jar el-api-2.2.1-b04.jar ibatis-common-2.jar ibatis-dao-2.jar ibatis-sqlmap-2.jar invoice-generator.jar itext-1.3.jar iText-2.1.0.jar j2ssh-ant-0.2.9.jar j2ssh-common-0.2.9.jar j2ssh-core-0.2.9.jar j2ssh-daemon-0.2.9.jar jakarta-oro.jar jaxrpc.jar jsch-0.1.20.jar jstl-1.0.2.jar jstl-1.2.jar junit.jar log4j-1.2.11.jar mailapi.jar ojdbc14.jar oro-2.0.8.jar poi-2.5.1-final-20040804.jar quartz.jar saaj.jar smtp.jar standard-1.0.6.jar stringtemplate.jar struts-core-1.3.10.jar struts-el-1.3.10.jar struts-extras-1.3.10.jar struts-faces-1.3.10.jar struts-mailreader-dao-1.3.10.jar struts-scripting-1.3.10.jar struts-taglib-1.3.10.jar struts-tiles-1.3.10.jar wsdl4j-1.5.1.jar xmlrpc-2.0.jar -----Original Message----- From: Christopher Schultz [mailto:ch...@christopherschultz.net] Sent: Monday, 23 July 2018 2:29 PM To: users@tomcat.apache.org Subject: [EXTERNAL] Re: Tomcat 5.5.17 migration to 6.0.53 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 David, On 7/23/18 12:51 PM, David Babooram wrote: > Hello > > I have begun a migration from 5.5 to 6.

Possibly. What files do you have in your app's WEB-INF/lib directory? - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAltWHmYACgkQHPApP6U8 pFi4ow//e1d8mPY8X7K2X1h2X9Maim12GIbKAv0OrvthWMWYMIt6POTrxRepJLg6 BxgQ2Duabf2wCmZhGRRcBotc7++Niyyh3bHPwy11UfsHXkLPQlE1bnfprgYsUI+5 JRUf4ZHLQ+HCXTn3R54U5Z+a6U4ucSotPt2FwpslIGH2lZFrjSjM+lELagNIJvvU gysavLRPZIQSCvDfPw1MeDbmtPalbVlq0XvS4d4szvWJy0oNzF1mRG4u6KWniisz t0ULSmp/2virBNPmQ9SdeoG23avPtfxVOY2BbP1O5IAjKSfhPV+UNhvu48ufq5gj gVYGVf5edxZy241ApGZHZoSSfl5LEiN1vJpIsF1a8HcqffhBTJTwtDzhscQDVxw9 89iiwTGEp5VtugI8vqMNI1hO9b0ESJhAfsCuMwvEvL2sivWWROXRzExsFiSFe0x2 K9tpqXBonXZ+4y+xwQdBoaDcRRjKhUW9rP5CbkNvDOfpttsnyD6c7ff1t/9K3vr/ FnBFCqo0qDRdSLckbtmU5C6/yHUjQiFtMXbMtnEVXwnk3zo0ICJnvxvTINp346nq EiYAMcZF+RemlO3+0whK+B7BKgF9L4baqvQmglJaIEVY2D6w4SmW/xCO55a4V2c4 gRD9xNP6u7M/dlFGs+VaJvdwkh4wNxj319vxYsZ2O2KsdmDdvUw= =YuGP -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org ________________________________ Notice of Confidentiality: The information contained in this communication is intended solely for the use of the individual or entity to whom it is addressed and others authorized to receive it.
