Can anyone help me get Roller 3.1 running on Websphere 6.0?I downloaded
the binary release zip and the extra required jars from java.net, and
unzipped them. I created the database, ran the script to create the tables
and configured the datasource to be mapped to the jdbc/rollerdb resource
ref. I created an appropriate custom-roller.properties file in
/WEB-INF/classes (specifying log file paths) and re-packaged the web app as
a .war file, which I've deployed into Websphere 6.0. However, when I
start the server/app I get a bunch of exceptions in the log:[12/07/07

through line by line in RAD7's debugger - sure enough, in the
HibernateRollerImpl constructor it catches the

expressions for the RollerConfig.getProperty values certainly look to be
returning strings to me (and at least it confirmed the roller-custom
properties file was being used). So two Strings aren't type compatible with
two Strings... Huh? No wonder the comment in the source says "// if this
happens then we are screwed" :-(Next I tried changing the classloader
behaviour to "parent last" rather than the default "parent first", in case
it's picking up the wrong version of something from the JRE. But that just
produced a different set of errors:[11/07/07 19:23:34:448 BST] 000000b9

guessing the LinkageError on SAXParseException is due to the org.xml.sax.*class
files being found both in WEB-INF/lib/xmlrpc-
1.2-b1.jar and also in Websphere's $JRE/lib/xml.jar ? Given they're
standard JAXP interfaces and have been included in the JDK since 1.4,
should they really be in the xmlrpc jar anyway? I also noticed the xalan
jar bundled with Roller is version 2.7.0 (according to
org.apache.xalan.Version), while the one included in Websphere's xml.jar(which I believe
is the one it would use for "Parent First" classloading
mode) is "XSLT4J Java 2.6.9". Assuming that's just their own build of
xalan 2.6.9, is there anything specific to 2.7.0 that Roller requires, or
should it be okay with the earlier version?I had hoped it wouldn't be too
hard to get this working, as they said in Covalent's recent Roller webcast
that "IBM use Roller for their developerWorks blogs, and they run it on
Websphere". However, although the HTTP response headers suggest they're
also using Websphere 6.0 ("Server: IBM_HTTP_Server/6.0.2.13 Apache/2.0.47
(Unix)"), I notice the roller.js script (http://www-03.ibm.com/develope
rworks/blogs/theme/scripts/roller.js) doesn't include the isblank function
near the end; looking through the different tags in Subversion, that
suggests they may only be running Roller 2.0.2 or earlier, as that's the
latest version of that file which didn't contain that function. I'd prefer
to use the current version than one that's nearly a year and a half
old. Does anybody have any suggestions how I can get 3.1 working? Has
anyone successfully got it installed into Websphere 6?Andrew.--
