Rob,
I'm working on a better patch! Should have something shortly.

Chris,
I got the same error. Is there something else I need to do besides run the mvn command?
Just to make sure we’re on the same page with regard to the change. I changed line 3196 of PresentationManagerImpl.java. Here is a snippet that includes 3196 (in bold):
try {
resource = getContentHosting().addResource(name, folder, 1, type,
bos.toByteArray(), resourceProperties, NotificationService.NOTI_NONE);
}
catch (Exception e) {
// unexpected error: tried to add new resource and failed
logger.warn("createResource(addResource): "+e);
}
}
String uuid = getContentHosting().getUuid(resource.getId());
return getIdManager().getId(uuid);
}
/**
*
* @param portfolios A list of Presentation objects
*/
protected void convertPortfolios(List portfolios) {
org.sakaiproject.tool.api.Session sakaiSession = SessionManager.getCurrentSession();
And here is the top of the stack trace. It looks pretty much like the one I was getting before:
org.sakaiproject.portal.api.PortalHandlerException: org.sakaiproject.tool.api.ToolException: Request processing failed; nested exception is java.lang.NullPointerException

Should I delete and recreate the maven repository and install a fresh copy of Tomcat and then do a fresh install of Sakai?
Thanks,
Rob

Chris,
I have updated the source file. My problem now is my unfamiliarity with maven (my development work is on a much smaller scale and I normally work exclusively in Eclipse). The directions I followed on the initial install were:
cd master
mvn clean install
cd ..
mvn clean install sakai:deploy -Dmaven.tomcat.home=/usr/local/java/apache-tomcat-5.5.31
How do I rebuild just osp/presentation?
Thanks,
Rob

Here's a link to the change:
http://source.sakaiproject.org/viewsvn/osp/trunk/presentation/api-impl/src/java/org/theospi/portfolio/presentation/model/impl/PresentationManagerImpl.java?r1=84414&r2=84413&pathrev=84414
That change is against trunk (haven't merged it back to any of the older branches yet (2.7.x, 2.6.x, etc), but I'd think it'd be in about the same place! Looking at the source file in 2.7.x, it's at line 3196 rather than 3284 of the trunk file.
Let me know if that's still too much and I'll come up with something easier for you!

Chris,
I created an account at jira.sakaiproject.org, but that’s the end of what I know about jira. So no, I don’t know how to get the diff. A quick go here and click there, etc, would certainly help.
Thanks,
Rob

Rob,
I was able to get it fixed. You should be able to patch and rebuild just a small part of osp. Do you know how to get the diff out of that jira? It's small enough that you could make the change by hand and then just rebuild osp (or just osp/presentation).

Chris,
Are we near a solution yet? Will this likely be a patch or a complete rebuild?
Thanks.

Rob,
Looks like a change made in this jira (http://jira.sakaiproject.org/browse/sak-18742) is now causing this problem.
No solution yet, but didn't want to leave you hanging!

Rob,
I was able to reproduce the error on a 2.7.x nightly instance so it's not likely anything that you've done wrong. I'll take a look and get back to you!

Subject: [Building Sakai] Getting NullPointerException testing source build of 2.7.1
Hi,
.
I built Sakai 2.7.1 from source using Maven 2.2.1 and then installed same in Tomcat 5.5.31. The System runs on Redhat ES 5. I followed the install from source instructions on the Sakai Project website (URL: <http://confluence.sakaiproject.org/display/DOC/Sakai+2.7> http://confluence.sakaiproject.org/display/DOC/Sakai+2.7), including setting java_opts within Tomcat, etc. I also tailored a sakai.properties file so as to include a proper URL and title. I assume that “By default, all Sakai distributions are configured to use an in-memory version of HSQLDB” means that I can leave database configuration alone at least until I’ve tested everything.
Here’s the problem. I created a new user, me, and I also created a new worksite and within that worksite I added a portfolio. For the portfolio, I chose Simple HTML and added a page containing only the line “My Portfolio”. When I clicked on the link to view the portfolio, the response was “An unexpected error has occurred.” And along with that, a lengthy StackTrace (included below).
This is my first time playing with Sakai, so I’m not sure what other useful information I can provide. Any idea why I’m getting the exception?
Thanks,
