Error description
Title: Unset deployment descriptor attributes become set during deployment. Abstract: Deployment processing, when writing deployment descriptor files, may incorrect write a set value for an attribute in cases where the attribute value was unset in the original deployment descriptor. Description: Application deployment processing may write deployment descriptor files, for example, the web-module deployment descriptor "web.xml" is written as "web_merged.xml", with values added which were obtained by annotations processing. The write of the merged descriptor should not write attributes with assigned values when those attributes are unset in the original descriptor, because a change to a set value can change the meaning of the attribute. For example, the web-module deployment descriptor "web.xml" has an optional "session-config" element, and this has optional "session-timout" and "tracking-mode" elements. Whether the "session-timeout" value is set (whether it appears in the deployment descriptor is significant): when absent, a value is provided by the web container; when set the configured value is used. <session-config> <session-timeout>120</session-timeout> <tracking-mode>COOKIE</tracking-mode> </session-config> The problem of this APAR is that an initial "session-config" which has just a "tracking-mode" element is written with both "session-timeout" and "tracking-mode": This original element: <session-config> <tracking-mode>COOKIE</tracking-mode> </session-config> Is written as: <session-config> <session-timeout>0</session-timeout> <tracking-mode>COOKIE</tracking-mode> </session-config> This problem also occurs in other locations, for example: Within "data-source" elements: "initial-pool-size" "isolation-level" "login-timeout" "max-idle-time" "max-pool-size" "max-statements" "min-pool-size" "port-number" This update addresses the problem for both both "session-config" "session-timeout" elements and for the listed "data-source" elements.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server * **************************************************************** * PROBLEM DESCRIPTION: Unset deployment descriptor * * attributes become set during * * deployment. * **************************************************************** * RECOMMENDATION: * **************************************************************** For this APAR, a problem occurred where XML elements were added to XML descriptor files during application deployment processing. For example, this initial "session-config" element, read from "web.xml": <session-config> <tracking-mode>COOKIE</tracking-mode> </session-config> Was written to "web_merged.xml" as: <session-config> <session-timeout>0</session-timeout> <tracking-mode>COOKIE</tracking-mode> </session-config> An identical problem occurs with the "data-source" elements: "initial-pool-size" "isolation-level" "login-timeout" "max-idle-time" "max-pool-size" "max-statements" "min-pool-size" "port-number" The "merged" deployment descriptor files which are created by the deployment, and contain a cache of module metadata as it will be used by the application server.
Problem conclusion
The "session-timeout" value should not be added during the write of "web_merged.xml". "data-source" child elements should not be added during the write of this data. A code update was made to correct these two problem cases. To preserve the prior behavior -- with respect to 'session-timeout' -- use the custom property "com.ibm.config.allow.set.session.timeout". The default for this property is 'false', which is to use new (correct) behavior. Set the custom property to 'true' to revert to the prior behavior for writing 'session-timeout'. The fix for this APAR is currently targeted for inclusion in fix packs 8.0.0.10 and 8.5.5.4.
