Newbie question: Server error when uploading Application

[SHawkins]

Hi Guys - I followed the instructions to add

"-Dsdn.signedJar=none \"  to /opt/sdn/virgo/bin/dmk.sh, as described in the HP VAN SDN Controller 2.3 Administrator Guide, pg 69, 5.8.2

I did stop & start the service as shown, and added it in the location shown - but when I try to add the example Health Monitor App, and click "upload"  I still get

App could not be verified: Unsigned file hm-api-1.0.0-SNAPSHOT.jar

Server Error – 400: Bad Request

URL: rs/apps

View ID: apps

Type: error

Any ideas or thoughts on how to get the VAN controller to run without checking signature?

I even rebooted the server just in case.

Exactly the same problem than you.

This add of the instruction "-Dsdn.signedJar=non"  worked with version 2.0 but no more with version 2.3.5 !!!

Could you help with the solution for this as I have tried a couple of things:-

1. Capitalised "Dsdn" to "DSDN".

2. In SDN UI on Configurations tab, changed "verifyZips" to "false" in App.Manager

After this got 2 different errors:-

(i) With Zip file containing UnSigned Jar files: "App could not be verified: Unsigned file"

(ii) With Zip file Signed Jar files: "App could not be verified: Signer not trusted (public certificate missing from sdnjar_trust.jks)"

Please suggest a solution.

I am having a similar problem with v.2.3.5. After building the sample Health Monitor App per the programming guide I tried to install the app on the controller. I get "App could not be verified: Unsigned file com/hp/hm/api/DeviceHealthService.class".  I also have verifyZips = false.

I've opened an HP support Case - 4736080403 - hopefully it will get routed to the SDN team so we can get this resolved for all of us :-)

Hi friends!

Setting -Dsdn.signedJar=none in /opt/sdn/virgo/bin/dmk.sh and setting  com.hp.sdn.adm.mgr.impl.AppManager.verifyZips to flase in HP SDN Controller Console worked for me.

There is another solution to upload apps smoothly, but it's not so convenient.

You need to properly sing every .jar and .war file in your app. In the guides, there is no advice how to achieve this. I didn't succeed with lots of experimentation and hours spent on this issue.

(I've just Install version 2.3.5)

For my part, with:

1) Setting -Dsdn.signedJar=none in /opt/sdn/virgo/bin/dmk.sh  and

2) com.hp.sdn.adm.mgr.impl.AppManager.verifyZips = false 

I can now UPLOAD all my  applications (I didn't before point 1) and 2) )

However when I try to Deploy my applications , It failed with the following error message:

Server Error – 500: Internal Server Error

URL: rs/apps/com.unil.arpsdn/install

View ID: apps

Type: error

Notice that the same applications worked correctly with version 2.0 !!!

An idea ?

Hi sbotkine,

sudo tail -n 256 /var/log/sdn/virgo/logs/log.log

will show you last 256 lines of virgo log where you can find app deployment exception stack trace, the cause of failure.

I think, the most probable cause of the error could be UnableToSatisfyBundleDependenciesException. In other words, you are referencig a library which is not available.

Thanks guys - I'm going to try the suggestions in the next couple days.

I really appreciate the help so far!!  Hopefully I don't run into missing dependencies.

Just wanted to update you all - 

I was able to get the Health Monitor application to Upload *and* Deploy.

One last question for now - do you folks know the correct URL to access the healthmonitor app, once installed?

What file makes this determination? (so I could change it, for example?)

Steps I took to allow the example Health Monitor app from the SDK included with 2.3.5 to install on VAN controller 2.3.5

1. Add  "-Dsdn.signedJar=none \"  to /opt/sdn/virgo/bin/dmk.sh, as described in the HP VAN SDN Controller 2.3 Administrator Guide, pg 69, 5.8.2, then restart the sdnc service

2. In the configurations section in the gui under com.hp.sdn.adm.mgr.impl.AppManager change verifyZips to false

HP VAN SDN Controller 2.3 Administrators Guide, pg 35 3.10.4

Thank you guys, and thank you HP Support!!

Not Sure, I retried everything but still could not get it working for me.

[TurboLuk]

I don't know details about healthmonitor app, so I'll try to asnwer you in a generic way.

For instance, we generated app using gen-sdn-app  --app myapp --company mycompany --subject MySubj --rest-path turbosubject ...

The default path to access MySubj REST API will be https://{CONTROLLER_ADDRESS}:8443/sdn/myapp/v1.0/turbosubject .

The default path to access GUI REST from outside the Admin Console: https://{CONTROLLER_ADDRESS}:8443/sdn/ui/myapp/app/rs/mysubj .

In other words,  you can access internal app in two ways:

1. via REST API, definition in "myapp-rs" project, and RSDoc: https://{CONTROLLER_ADDRESS}:8443/api/ ,
2. via Admin console, definition in "myapp-ui" project.

Both are basically classic Java Web Services hosted on Tomcat. Each project Tomcat treats as an independent application, .war file. Each Tomcat app has a descriptor, usually web.xml. You can find it in project folder under: src/main/webapp/WEB-INF/web.xml. We only need to edit section near to com.sun.jersey.config.property.classnames  which "activates" our ControllerResource defined in project. Each class which extends ControllerResource has @Path annotation, this determines the suffix of REST path.

I hope, I answered your questions completly despite the fact I'm not from HP and I'm not a Tomcat expert.

[SHawkins]

Thanks so much TurboLuk! Your answer is exactly what I needed and more than I had hoped for!

Hi ALL,

We are glad that your problem is solved, please let us know if you still face any issue.

The correct and working steps to upload the application (e.g. Device Health Monitor)  mentioned as below

1.As per Admin guide 2.3 page 35-36 please make sure that verifyZips key value is false under com.hp.sdn.adm.mgr.impl.AppManager     component.

2. AS per the Admin guide 2.3 page 68-69 please follow as  below

a) sudo service sdnc stop

b) make an entry -Dsdn.signedJar=none \     in the file /opt/sdn/virgo/bin/dmk.sh 

e.g.

cd $KERNEL_HOME; exec $JAVA_EXECUTABLE \

$JAVA_OPTS \

$DEBUG_OPTS \

$JMX_OPTS \

-XX:+HeapDumpOnOutOfMemoryError \

-XX:ErrorFile=$KERNEL_HOME/serviceability/error.log \

-XX:HeapDumpPath=$KERNEL_HOME/serviceability/heap_dump.hprof \

-Dsdn.signedJar=none \

-Djava.security.auth.login.config=$AUTH_LOGIN \

-Dorg.eclipse.virgo.kernel.authentication.file=$AUTH_FILE \

c) start the sdnc service by running

sudo service sdnc start

Please try the method mentioned as above and let us know if you still face any issue.

Thanks,

HP SDN Team

Hi TurboLuk OCCASIONAL ADVISOR!
Thanks a lot for sharing the solution with us. I’m also facing the same problem few days back but didn’t get any appropriate solution. Your idea helped me.
