If you want to perform up/download related operations via ITS, then Java applet needs to be installed on the client side.
To make sure Java applet works normally, you need to make sure the settings are correctly maintained.
Network settings should be the same as the browser network settings (use browser settings), otherwise the java applet package ws.jar could be loaded over a different network path.
Under Temporary Internet Files settings the cache could be deleted and deactivated (for problem analyzing) to be sure not to get an old cached applet.
You can checked the JVM version enabled in this tab (you can have multiple JVM version installed on the same client):
By the way, you can also determine JVM version using the following methods:
①Via Java trace: In the first
several lines of Java trace, you can find information like below:
Java Plug-in 10.45.2.18
Using JRE version 1.7.0_45-b18 Java HotSpot(TM) Client VM
User home directory = C:\Documents and Settings\<User name>
This means the JVM version is 7 update 45.
②Via Oracle – Call the following URL
Then the JVM version will be determined.
The flag “Enable Java content in the browser” should be checked.
Default security level is high, but up/down applet runs also under setting very high with note 1920875 – ITS Up/Down: different problems in java plugin because of new security restrictions
Exception Site List can be used to check, if current applet does not fulfill the new security requirements.
If one would like to be informed about the applets certificate, the SAP AG certificate from the trusted certificate list should be removed (for problem analyzing).
This tab can be used to create Java console trace, more details about how to create Java trace can be found in <KBA 2078323 – How to get
Java control trace for upload or download problem on SAP GUI for HTML> .
