Blocks Editor - Unable to launch application

[Alvsky]

Hi,
I have WinXP and I managed to start server with no problems. I also started the Designer (localhost:8888).
But, when I try to run Blocks Editor I get Allpication Error - Unable to launch application!
Under Details it says:
Error: Cannot find cached resource for URL:http://localhost:8888/ode2/webstartfile/......./BlocksEditor.jar

I installed Java 7 and set the JAVA_HOVE variable to c:\Program Files\Java\jdk1.7.0_25\

I hope there is a simpe solution to this that I overlooked :) so if someone can help me with this, I would appreciate a lot

Thanks

Had the same issue under Win7, but after some research (thanks Google!) the culprit seems to be Java.

I managed to fix this by changing a couple of things in Java settings (Start -> settings -> control panel -> Java)

1) Changing the setting so Java doesn't keep temp files on the PC.
- This is done by going into the General tab in the Java Control Panel, clicking on Settings under Temporary Internet Files and UNTICKING the box next to Keep temporary files on my computer.

2) Lower the Security Level in Java settings.
- In the Java Control Panel, navigate to the Security tab, slide the bar to the bottom.
*NOTE After I managed to get the Blocks Editor working, I replaced the bar to the default option (High) and it still seems to work fine. Could mean that you can skip step two.

The above seems to have done it for me, but if not, take a look at the following link:

...which is where I found out about changing the settings.

ONO, Thanks for your input

I just tried your advice and it works fine now on win7.
It works fine without step 2. So all it should be done is to change the caching.

Thanks a lot ONO

I run Ubuntu, Everything seems to work fine so far except the block editor. It wont load on chrome. I thought I had fixed the JNLP problem but no - it seems to just keep downloading multiple files. On firefox it tries to open endless tabs & crashes the browser. I assume its trying to open multiple temp files. I will take a look at the JAVA settings.

UPDATE: I unchecked temp java files & no change . security has no slider only certificates. The JAVA control panel in Advanced an option to allow JNLP files to run as mime type. Checked this but no change in the error.

I will try this next

OK I finally just got it to actually run by associating it with JAVA web start not chrome or firefox.

i will play around later & get it to run straight from the browser
