I?m using the Java Connector in a little App and it works fine but my colleague faces many problems with the Java Connector. He uses the same App and the same version of the SAP Was 6.30 Sneak Preview. Every time he deploys the app he got error messages that the sapjcorfc.dll isn´t found. The JCo only works after he copies the dll into the WINNT/System32 directory and deployed it with the App. A third colleague also has no troubles but he has the SAP GUI installed.
In this context there is a strange behavior of the server: all changes made only shows an effect after restarting the server. Is there any caching of the ?internal state??
