Liferay無法編譯JSP的類

我遇到了Liferay 5.2擴展系統的問題，問題是在某些環境中工作，而在其他環境中工作。在失敗的環境中，它會拋出這些異常。Liferay無法編譯JSP的類

23:32:24,363 ERROR [IncludeTag:78] Current URL /web/guest;jsessionid=BFE790BBC107B870740C0268238CEA16 generates exception: Unable to compile class for JSP:

環境具有相同的Ant，Tomcat和Java安裝。我也授予我的Tomcat目錄的所有權限。有任何想法嗎？

判斷由於它是編譯問題而GroupConstants.COMM_CATEGORY_AWR不是GroupConstants的標準Liferay常數。我會仔細檢查以確保您正在導入正確的GroupConstants類，並且您已正確部署了您的代碼。

謝謝，我們實際上使用我們在工作環境中使用的相同過程來部署系統，我們甚至到了GroupConstans類並反編譯它以確保代碼在那裏。由於在其他機器上工作，導入是可以的。 – Hanzel
