OCI 7.0.2 Java UI and Java version issues

Hi,

 

some OCI 7.0.2 users are notifyng me that they're not be able to run Java UI from the "coffee cup" link on the OCI web portal in a lot of cases.

I know that Java 7 is a prerequisite but installing ONLY Java up to 7.21 it works but with newer versions up to 7.75 and 8.x the Java UI does not start at all.

 

Once clicked the button some seconds of wait and then nothing happen and in the task manager there's an appended java process.

 

This customer report me that they've some domain policies that automatically update their Java runtime versione so they cannot use the OCI Java UI.

Is there a way to let coexist older versions and the new Java one? 

Assuming they're forced to use the last one (i.e. 😎 are there some tricks?

 

Regards,

Here's a workaround doc I wrote for my company for java compatability issues. You can have an older java version installed simultaneously with the "current" release and then use a windows shortcut to invoke that java directly against the server. The coffe cup UI will not work, but a deskop shortcut is actually more convenient anyway. πŸ˜‰

Hey Giacomo,

 

There is a server-side patch to OCI 7.0.2 that allows co-existance with Java 7/71-72-75 and 8u23-8u31 on the client side. Do you have that patch installed?

Uh! I didn't know it! But also NetApp guys here did not know it πŸ™‚

 

I will get from support.netapp.com download pages...

 

Thanks!

Where's is this patch?

 

The last available is for 7.0.1 only (read in the notes)06-02-2015 17-14-55.jpg

We don't have individual patches available on support.netapp.com - it can be obtained via a support case

If my boss can follow it, you should be ok.

ok so i have a windows 8.1 desktop with Java 7 build 60 64 bit installed

been battling this issue described in the article here and have tried the workarounds but no luck - not the exact same error but getting a different one:

I would assume with all the vulnerabilities being shown for older java versions and MS activex blocking that OCI will be forced to upgrade to a newer version of supportable java - is this in the works? or even get rid of java completely? πŸ™‚

i have created the shortcut listed here a few different times but its the shortcut getting this alert - any ideas?

Hey Pete,

What version of OCI are you running? Has the OCI client ever worked from the machine? What you are seeing is a SSL/TLS negotiation problem. Is your workstation configured with any non-default Java settings for TLS/SSL ?

If you drop to a cmd prompt, and

ping servername

Does that resolve to the right IP address?

You may also want to drill into Control Panel -> Programs -> Java. In the Java Control Panel, you may want to review the network connection settings - are you going through a proxy? Should it be?

 

 

PeteHanson

Thanks for the prompt response

we are running OCI version 7.0.2 build 164 so it should be pretty up to date

as for the java client no it has never worked from this machine

as for the pinging of the server (I changed the name) we can open up the web client without issues and i can ping the server

i am running standard java settings but have tried to set non-standard ones - i am not the only one having this issue as our entire team here has the same errors when launching the client

when i open a command prompt and ping the server name it does reply and resolves to the correct IP

my java is not going through a proxy server

Does the Java client work on the OCI server itself?

 

If you are sending OCI ASUP, PM me the site name, and I will poke through the logs

 

Things to try

Java Control Pnael

General -> Temporary Files Settings -

make sure disk space is not set to none for caching files -that causes weird behavior.

Delete Files -> Enable all three check boxes -> click Ok - this will clear out the client side cache - if you re-launch the Java UI from the OCI WebUI, it will re-download the client entirely as none of its bits will be cached locally - this sometimes clears up client pain

 

Advanced

 Enable Tracing

 Enable Logging

 

Check those two checkboxes before launching the Java client - it will generate more logging into

 

c:\users\matt\AppData\LocalLow\Sun\Java\Deployment

 

Where "matt" is your Windows username.

PeteHanson

yes it does

 

PeteHanson

OK i missed a second part of your question

the checkbox for temporary files is checked on my computer

all 3 boxes were checked

the advanced settings were checked already so i will take a look at the file in appdata to see if it shows anything

PeteHanson

here is the java trace file generated when i open the link remotely:

Log started: Tue, 24 Mar 2015 13:14:55 -0500
Java Web Start 10.67.2.01
Using JRE version
 1.7.0_67-b01 Java HotSpot(TM) Client VM
#### Java Web Start Error:
#### Unable to load resource: https://servername:443/client/app/http-client.jnlp

 

 

i tried adding in the exact link on the OCI server for this that does work and had no luck - is it related to the version of java?

ostiguy

Highly doubtful.

 

The way the Java client works is roughly as follows:

Download JNLP file via https

Parse JNLP file - download code via HTTPS

Bootstrap client

Client initiates https connection to server

 

You are basically stuck at roughly phase 1, or the start of 2.

 

It doesn't make much sense why you can download the JNLP via a browser, and then get this error message, unless the browser has a different communication path to the OCI server from what Java would have, but it sounds like we have ruled this out as no proxies are in use with the browser or Java.

 

PM me your OCI ASUP site name if you are sending us extended logs, and I can see if anything interesting is happening server side

PeteHanson

is it possible to manually download the bootstrap client and bypass all of this?

No, it is not

THis Last options to correct the network proxy worked for me!

I was initially using the Browser Proxy but when I changed to Direct it started to work.

 

THanks Guys.

Thanks.

Now I've tagged as a solution your answer but if it fails I will untag it Smiley Very Happy

Has this issues been resolved?

 

I have OCI 7.0.2 build 164 and from Windows 7 client using Chrome and latest Java (8.0.45) the UI just will not complete. It downloads the app when first run and then nothing.

 

I can't use previous Java versions (no option in our company), so the previous solution is not possible.

 

What other options are their for configuring/changing annotations etc. Is there only the Java UI?

 

thanks in advance for suggestions/ideas/help.

Yes, this issue is resolved, but you resolve it by deploying a server side OCI patch - this patch will resolve the issue for all the Java client users of that OCI instance.The forthcoming OCI 7.0.3 and 7.1.0 releases will not need a patch. For annotating objects, there are a few different options: The OCI annotation import utility is a CLI jar tool that can annotate objects from a .CSV. This is the most common approach for customers who have a CMDB that has host .-> application relationships, and want to bring that data into OCI . There is now some REST API tooling that allows you to set annotations as of OCI 7.0.2 and higher. Not all objects are yet capable of being annotated this way. Finally, one can manually annotate objects in the Java client.
