Hi Seshu,

Some probable steps that you can try doing are:

- It is recommended to have a minimum of JRE 1.4.2 or higher. But it’s better not to have JRE 1.4.2_10 and above as it has been noticed to throw errors.

- To avoid auto updates of J2SE to higher versions go to the control panel and open the Java Plug In icon. Browse to the update panel and uncheck the checkbox for Check for Updates Automatically.

- Open Web Start and go to Preferences. In the General tab you will find 3 radio buttons for proxies. Select the None option.

- Try clearing the cache folder Java Web Start>File>Preferences>Advanced>Clear Folder and then try downloading the jar files again.

Also go through the following links:

Hi Seshu,

Do this...

Go to this link in your computer..

C:\Documents and Settings\<your user folder if any>\Application Data\Sun\Java\Deployment\cache\javaws\http and access the .jar files for your repository.

I am telling you this because, your jar files could be corrupted. If they are corrupt, your jar file will have no icon( the windows logo icon will be there). Delete these jar files(only the error ones), and restart the repository. Just a hunch. Please be careful when u do this!

Also look at this link :

Click on the Administration tab on the Integration Builder homepage. Under the repository and directory tab what do you see as the jdk.version?

Also where are you seeing 1.5.0_07? XI is not completely compatible to run on 1.5 it is much safer to use any version below that.

Hope that helps.

Hi,

The Integration Builder page itself not displaying..

about the version 1.5 its on the different system, where XI is running.. and the error i am getting on my notebook where i am getting trouble.

Thanks

Start a command prompt and type <b>java -version</b> does it show your Java 1.4?

Are you having the same issue for the Repository as well as the Directory?

[Former Member]

Hi,

i have same issue for both..

Java -version shows 1.4.2_06 in system where i am getting error.

and where XI is running fine..it shows 1.5.0_07

Make sure in your Java Web Start -> preferences, the proxy is selected as none and the Java version enabled is Java 1.4 and not 1.5. Also are you trying to connect through your company VPN? Sometimes I have had that issue due to the wrong java version enabled in java Web Start or VPN issues.

[Former Member]

Hi,

Thanks for reply, i tried your option. i have only one Java 1.4 in my system and its enabled..

Proxy also selected as none..

I am using direct PC, not using VPN..

Do i need to restart Java Web Start? how can i do that?

any other options?

Thanks

Seshu
