ACF up/download no longer working !

[Former Member]

Hi,

About a month ago I got Thomas' web dynpro up/download ACF example application working - and all was good. Now when I try to run it (with a view to using ACF in my own application) it doesn't work !

Using httpwatch I can see that there is no call to the ICF handler, and after enabling the java console it seems there are two kinds of exception:

UPLOAD:

Exception in thread "kpro thread0" java.security.AccessControlException: access denied (java.io.FilePermission C:\temp\upload\canYouDigIt.jpg read)

...and then the application hangs (perpetual spinning doughnut).

This time the application doesn't hang.

Both of these look to be permissions related, but I have write access to the folders in question, and the whitelist is setup like this:

<download>

<directory>$HOME/SAPWORKDIR</directory>

<directory>c:\temp</directory>

<directory>c:\temp\download</directory>

<server>http://isudvjd4.uk.blahplc.com:8000</server>

</download>

<upload>

<directory>$HOME/SAPWORKDIR</directory>

<directory>c:\temp</directory>

<directory>c:\temp\upload</directory>

<server>http://isudvjd4.uk.blahplc.com:8000</server>

</upload>

I think I have upgraded my Java runtime in between it working and not working, and security patches may well have been applied, but I would expect to get some security/certificate warning if this was the problem ?

Any ideas anyone ?

Thanks,

Hi

I have experienced the same problem even after installing

JRE 1.6_24. The app just hangs. What I did was to regenerate

SAPFrontEndService.xml and SapFrontendServiceXXXXXXXX.cert

usng transaction WDR_ACF_WLIST.

This fixed the problem

Well, after much head scratching, I finally found the problem. The Java version I was using on my PC (1.6.24) is incompatible with ACF - switching to 1.5.something fixed the problem.

That's a bit odd: help.sap.com (http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/b9157c878a2d67e10000000a42189c/frameset.htm) says you need 5 or higher, and points to an OSS note (http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/b9157c878a2d67e10000000a42189c/frameset.htm) which says you need 1.6 update 12 or higher......

Hi Nick,

I'm experiencing the same issue. Did you or anyone else find any other solution for that? Because Java 1.5. is no longer supported.

We're on a SAP BASIS 702 Level 8 System.

thanks in advance

Interestingly if I remove the whitelist from the ApplicationData\SAP folder the applet throws a 'valid whitelist not found' exception, and this is also reported via the application, so it is definitely finding the whitelist......

Have tried this in Firefox today, and exactly the same thing happens.
