Integration Builder: Unable to launch the application.

Former Member — Mon, 03 Oct 2011 12:28:54 GMT

Hi,

I'm on PI 7.11. we just implemented SPS 06.

We're on DB 9.7 FP3 and AIX 5.3

I am trying to start the integration builder. Sometimes it works, sometimes it fails.

when it fails, I get a popup with this info:

Unable to launch the application.

Name: Integration Directory

Publisher: SAP AG

From http://my_server_name:53000

When clicking on the DETAILS button, under the Exception tab, I find:

java.lang.NoClassDefFoundError: com/sap/aii/ib/gui/misc/ApplicationBase

... 15 more

Like I said earlier, If I try over and over again, I eventually get it to start normally!

For additional info, I'm using:

java version "1.6.0_20"

Java(TM) SE Runtime Environment (build 1.6.0_20-b02)

Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

Note that this issue also happens on other workstation. The only thing that changes is installation of SPS06.

Thanks.

Just few cents...

Are you in a Local Network under a Proxy Server?

It seem like an old issue with Java RE ... when it can't load the application, caused by Proxy Settings in Java ControlPanel or Certificate authentication...

Re: Integration Builder: Unable to launch the application.

Former Member — Mon, 03 Oct 2011 13:25:43 GMT

Thanks spantaleoni for you answer.

I am not under a Proxy.

I searched SAP notes and found a few notes about Certificate authentication. I am not sure if this is the case here as the error message does not seem to be related... but I may be wrong.

Hi Mr Brunelle,

I'm referring to Java RE Protected Certificate (like SAP AG or similar), but I may be wrong.

I've no problem with SP6 in PI 7.11 system, but this error seem to be related to JRE on local Machine.

ps. if you have pleasure, please add me on gtalk

Did you check the file in the path C:WINNTsystem32driversetc or C:WINDOWSsystem32driversetc. This file contains the mappings of IP addresses to host names with FQDN

Also please check this blog

Former Member — Mon, 03 Oct 2011 17:55:21 GMT

Hi,

i checked hosts file. All looks fine.

Please remember that my problem is intermittent! It works sometimes... it fails sometimes.

Hi Eric,

Try opening http://<host>:<port>/rep -> Administration. In Repository and Directory tabs, go to Java Web Start and click the button Re-initialization and force-signing.

Hi ,

Follow the below steps:

1.Open your C:\ folder

2.Next go to your Control pannel~~->there u can find Java(TM)~~->double click on that

Hi chichilin,

I did not find the "administration" link from /rep link.

Hi preethi_malu,

I tried your procedure and it did not work... and as I stated, after 3 tries, it worked... but failed after try #4.

I found something very interesting:

When I try repeatedly to download the integration builder file directory.jnlp, I get multiple versions downloaded with names such as directory-12.jnlp and directory-13.jnlp.

These files are not the same file size! They do not have the same contents! how could that be.

That makes be believe that problem is on the server it self and NOT on the workstation.

The working one has this text in it:

the one that is failing:

Also, when I double-click on the directory-12.jnlp file, it ALWAYS work!

when I double-click on the directory-10.jnlp file, it always FAIL!

Hi Eric,

Go to TCODE:SXMB_MONI --> you will get a popup window which has IR,ID,SLD and RWB

in the right hand side you will have an option called administration ..just login to that page with your user credentials and if you see at left pane you will find an option for repository -->Javau2122 Web Start Administration and also Directory --> Javau2122 Web Start Administration for re-initialization and reinitialization force signing.

just click on these two then try after 5 min.

Regards,

Naveen.

Hi chichilin and Kumar,

When I go into transaction, I get into a transaction that looks like SPRO:

I finally found the "Administration" tab everyone is talking about. So, I tried it, logged in.

Unable to remove lock

I am stuck again!

Do you mean option "Restore Archives and Generate New Signature" from the Java Web Start Administration option?

Re: Integration Builder: Unable to launch the application.

naveen_chichili — Tue, 04 Oct 2011 15:22:52 GMT

Hi Eric,

1. Login to your XI/PI server

2. Go to Exchange Infrastructure Tools main web screen. You will see

Tools list and other options.

http://SERVER:PORT/rep/start/index.jsp

3. On the Upper right part of your screen you will see Tools

Administration Client Installation and Guidelines Documentation.

Click Administration

4. Login with user.

5. On the Exhange Infrastructure Administration , make sure you are in

the Correct tab. (Repository Directory Runtime). The tab will

determine the administration configuration that your will perform

5.1 When this problem occur with Integration Repository > make sure you

are in Integration REPOSITORY TAB. Proceed with step 6. Skip step 5.2.

5.2 When this problem occur with Integration Directory > make sure you

are in Integration DIRECTORY TAB. Proceed with step 6.

6. Click on Java web start administration.

7. Click on Re-initialization and force-signing. This will

re-authenticate all new JAR files deployed. This will also let the new

JAR files adapt to the current certificate deployed.

This function will cause the above re-collection and additionally a

re-signing of ALL resources with a dummy certificate. The original SAP

signatures of the jarfiles will be lost. To get back the original SAP signatures

the application has to be deployed again.

8. A Java(TM) Web start Application reset text will appear.

9. Wait for 5 to 15 minutes for re-initialization to complete

10. Start your "Integration Repository' or "Integration Directory"

again. It should work now.

This will solve the issue

With regards

Naveen

thanks for the very detailed post.

in option 7:

7. Click on Re-initialization and force-signing. This will

re-authenticate all new JAR files deployed. This will also let the new

JAR files adapt to the current certificate deployed.

I do not see such option I see the following text (button are in BOLD)

Status

Initialization Status Display

List of Resources Display

JNLP File Display Start Application

Re-Initialization

Restore Archives Choose this function to restore the Java Web Start archives at the client. All JAR files will be collected and placed in a global directory (sys.global.dir). Any JAR files that do not already have a signature will be assigned a new key. The system will also apply a lock to avoid simultaneous processing

Restore Archives and Generate New Signature Choose this function to restore the Java Web Start archives at the client and to assign a new key to all archives. The original SAP signatures for the JAR files will be deleted. We recommend that you only use this function in test systems. To restore the original SAP signatures, you must deploy the application again

Remove Lock Use this function only if a previous attempt to restore archives terminated with errors and consequently a reconfiguration lock has not been deleted. Before use, ensure that no collection process is running (as is the case if you have restarted the J2EE server, for example) otherwise errors can occur

naveen_chichili — Tue, 04 Oct 2011 19:09:27 GMT

Hi Eric,

You would be able to see Re-initialization and force-signing option just below Re-initialization just click on that and try to open IR and ID after few min's.

Naveen
