Grails

The root cause is not shown in the error, is there any other error log files which show the actual cause of the NPE

This is all I get - I don't have visibility into the weblogic.server.internal.EventManager line 458.

I turned the debugging way up on weblogic but no more information.

Could you show your weblogic.xml?

I don't see 10.2 as a download option at http://www.oracle.com/technetwork/middleware/ias/downloads/wls-main-097127.html to test with but I was able to deploy a simple application to 10.3.5. Are you able to upgrade?

reducing priority, awaiting feedback

There's no such thing as WebLogic 10.2 (http://en.wikipedia.org/wiki/Weblogic#Application_Server_versions). I recommend closing this issue. Thanks, Bobby

closed to lack of feedback

Sorry I had to quit this project. Now just getting back into things. Regarding Weblogic 10.2 comment by Bobby - it does exist, it's "Weblogic Platform": http://docs.oracle.com/cd/E13196_01/platform/suppconfigs/configs102/102_over/overview.html
... which consists of WebLogic Server 10.0 MP2. Same thing. I should've referred to WLS 10.0 MP2 - I think that alone would produce same results.

I'm updating my env to use same app, and deploy to same server, but using grails 2.0.3 and STS 2.9.1, still jdk1.5 compatibility.

Grails 2.0.3 doesn't yet run on JDK1.5 because grails-datastore 1.0.4 version has been compiled for JDK 1.6 . The problem is fixed and will be released in 2.0.4.
Add this dependency to BuildConfig.groovy's dependencies to upgrade grails-datastore in 2.0.3 :

compile("org.grails:grails-datastore-gorm:1.0.7.RELEASE", "org.grails:grails-datastore-simple:1.0.7.RELEASE", "org.grails:grails-datastore-core:1.0.7.RELEASE") {
                transitive=false
        }

Thanks for the info! Was just going down this path but was trying to do a runtime include on 1.0.7 along with an excludes on 1.0.4 of grails.datastore.core, but that's not working - I'll try your suggestion next.

It seems that the JDK 1.5 issue also exists with commons-dbcp. I'm not sure where this dependency is coming from, in the ivy-dependency report it's saying from organization org.grails.internal requires commons-dbcp 1.4. If you look at http://commons.apache.org/dbcp/ it says that 1.4 only works with jdk 1.6.

Tried adding 'org.grails:grails-datastore-core:1.0.4.RELEASE' to my BuildConfig excludes but it's still there. Ideas?

So this is where I'm stuck in deploying to WLS, I can't figure out how to force the compile to downgrade commons-dbcp to 1.3 from 1.4.

Can we reopen this ticket?

Here's the log output, it's the first thing I see after Weblogic is ready to start deploying the war:

commons-dbcp 1.3 gets used when grails.project.target.level==1.5

Do you have these settings in BuildConfig.groovy?

grails.project.target.level = 1.5
grails.project.source.level = 1.5

Did you add this to BuildConfig.groovy dependencies? (it should be defined in "compile" scope since that's where it's defined in Grails.)

compile("org.grails:grails-datastore-gorm:1.0.7.RELEASE", "org.grails:grails-datastore-simple:1.0.7.RELEASE", "org.grails:grails-datastore-core:1.0.7.RELEASE") {
                transitive=false
        }

Run "grails -refresh-dependencies clean; grails compile; grails dependency-report" to verify that correct versions of grails-datastore-gorm, -simple & -core + commons-dbcp get resolved.

Hi - Thanks again for your help with this.
So commons-dbcp is at 1.3 and only Evictions I see in IVY report are the two datastore evictions from 1.0.4 to 1.0.7 as expected. Now I'm getting a diff ClassDef error. Here are the first two messages and then relative snippits from the enormous stack trace:

Seems like progress. Poor visibility into what the problem is with AbstractDatastore....

Anything you want me to try?

Daniel, Can you check the content of the war file? What jar files are there under WEB-INF/lib? Is grails-datastore 1.0.7.RELEASE used or do you see any 1.0.4 jar files?

I got 3 evictions for grails-datastore related dependencies. Do you have all 3 specified in BuildConfig.groovy's dependencies:

compile("org.grails:grails-datastore-gorm:1.0.7.RELEASE", "org.grails:grails-datastore-simple:1.0.7.RELEASE", "org.grails:grails-datastore-core:1.0.7.RELEASE") {
   transitive=false
}

OOPS! - My screen was at perfect width to see exactly two exclusions in your compile entry above.

Sorry about that. Trying again.

That did the trick it seems. But I have some weird artifact here - my default grails home page doesn't load.... no log msgs or anything either.

I CAN get to one of my controller list pages, and do everything there is to do... but that default home will not load.

Also wanted to mention - this project started as a grails 1.3.7 project now running as grails 2.0.3.

I can see that it's listed in the war file views, and in classes I see the gsp compilation of index page.... Only thing I see in weblogic is:

At least we're past the DB issue and my controllers work now. Should I look for/submit new Jira for this last issue? The title still sort of captures my issue I believe...
Thanks,
Dan C.

Is your "home page" a GSP called grails-app/views/index.gsp ? In Grails 2.0 there was a change that you cannot access GSPs under grails-app/views directly any more (GRAILS-7542). If that's the case, you can move the index.gsp GSP to the web-app directory.

There seems to be a Jira issue about this problem already: GRAILS-8767 . I'm not sure if it's a real problem or just caused by the GRAILS-7542 change.

Daniel, there is a workaround for your problem.

Sorry to have all the issues... Still pretty new regarding the magic parts
The workaround worked for the default index.gsp, How do I get the rest of the index actions to work?

One interesting thing to note is that where I don't define anything in the controller for index, it works, and where I have a redirect or something - it doesn't work:

Doesn't work:
CmsEnvController:
def index = { log.debug("index") //Doesn't print redirect(action: "list", params: params) }

Does work:
DonwloadsController:
def index = { //nothing, default to index.gsp }

I'll attach the log output for when I click on the CmsEnvController from the home page (which goes to index).

Can't attach - probably because this issue has been closed.....

in CmsEnvController above, there's a carriage return after "//Doesnt' print".
The next linke would be a redirect.

So I'm not noticing that this controller method gets called at all when I go to index url.
