PTC Thingworx：java空指針異常

TW 6.5.5在正確配置warg文件後，正確配置postgres，提供java空指針異常。它看起來與不正確的證書（檢查下面的application.log）有關，但是也遵循Web上檢索的指令來管理modelprovideconfig.json文件，但仍然沒有機會正常工作。有什麼想法？PTC Thingworx：java空指針異常

可能重複[什麼是空指針異常，以及如何解決它？]（http://stackoverflow.com/questions/218384/what-is-a-null-pointer-exception-and-how -do-i-fix-it） – soorapadman

謝謝Soora：那裏沒有任何編程。看看建議的主題，但沒有機會檢索到mu問題的可能連接。這肯定與某些憑證問題有關。 – Luca

我找到了解決辦法！ Postgresql只能安裝在Windows驅動器（c :)下：在不同的情況下（其他本地驅動器）安裝失敗。另外apache/tomcat（以及我的webapp在最後）必須屬於同一個磁盤（這導致java nullpointer異常）。一種可能的選擇是將固定代碼集成到ordero的apache/tomca server.xml config.xml文件中以嵌入所有apache/tomcat web應用程序憑證。因爲我的web應用程序指向一個.json文件並引用postgresql實例，除了將它放入本地rrive :-) 就沒有機會了。
