Benjamin P Ross resolved GEODE-6867.
------------------------------------
Resolution: Done
> Fix documentation for session state caching
> -------------------------------------------
>
> Key: GEODE-6867
> URL: https://issues.apache.org/jira/browse/GEODE-6867
> Project: Geode
> Issue Type: Bug
> Components: docs, http session
> Reporter: Ryan McMahon
> Priority: Major
> Labels: GeodeCommons
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> This story outlines two major issues in the session state docs, but I think
> the docs deserve a fairly comprehensive review to determine if there is any
> other stale/incorrect information. The two issues are:
> # Required jar list is missing some required jars
> # Need to indicate that a locator MUST be available for peer-to-peer topology
> More details on both issues below:
> We should review the session state documentation for
> completeness/correctness. When attempting to install and configure the
> Tomcat and AppServer session modules by following the docs, I found that
> there were missing jars in the [installation
> section|https://geode.apache.org/docs/guide/19/tools_modules/http_session_mgmt/tomcat_installing_the_module.html]
> for Tomcat and [setting up
> section|https://geode.apache.org/docs/guide/19/tools_modules/http_session_mgmt/weblogic_setting_up_the_module.html]
> for AppServer. Namely, I had to add these missing jars (as of 9.8, maybe
> earlier).
> * micrometer-core jar
> * geode-commons jar
> * geode-management jar
> The first is a new jar added since this documentation was written, and I'm
> assuming the code was restructured to require the other two jars as
> dependencies. I'm not sure how we can ensure that this list is up to date.
> Some of our system level tests for session state have to include the same
> list. From TomcatInstall.java:
> {code:java}
> private static final String[] tomcatRequiredJars =
> {"antlr", "commons-io", "commons-lang", "commons-validator", "fastutil",
> "geode-common",
> "geode-core", "geode-management", "javax.transaction-api", "jgroups",
> "log4j-api",
> "log4j-core", "log4j-jul", "micrometer", "shiro-core", "jetty-server",
> "jetty-util",
> "jetty-http", "jetty-io"};{code}
> And you can see that this list was updated to make the tests pass when
> dependencies changed.
> The other major issue I found while running through the steps is that you
> MUST start a locator in the peer-to-peer topology for session state, because
> multicast UDP discovery is not available/supported in Geode.
