PLM7 SAP DMS Applet failure when using administrated Java plugin

Hello,

at the moment we are facing a strange issue. When using the latest PLM7 SP3 for EHP 7 the DMS applet is not running in an environment where SUn Java Plugin is admintrated with a deployment ruleset.

Does anybody has the same issue, or has anybody no problems in using the applet in combination an administrated SUn Java Plugin (deployment rulesets)
