無法編譯JSP的類

Iam使用NetBeans在JSP中處理項目。無法編譯JSP的類

蔭收到以下錯誤......但我沒有找到Java任何files..please我提供something.The錯誤是：

org.apache.jasper.JasperException: Unable to compile class for JSP: 

An error occurred at line: 205 in the generated java file 
Syntax error, insert "Finally" to complete TryStatement 

An error occurred at line: 206 in the generated java file 
Syntax error, insert "}" to complete ClassBody

堆棧跟蹤：

try { 

/*Getting the connection variable from session*/ 

con=(Connection)session.getAttribute("connection"); 
stmt = con.createStatement(); 

String Query = "SELECT * from student where studentid = \'"+disluserid+"\'"; 
System.out.println(Query); 
rs = stmt.executeQuery(Query); 
} catch(Exception e) { System.out.println("Exception"+e);

在你沒有完成的try的catch塊上面的代碼段。

謝謝.......但你能告訴我，我可以在NetBeans項目中找到java文件的位置。我不好嗎？ – 2011-05-07 09:49:08

等2分鐘我會告訴你。 – Ankit 2011-05-07 09:49:52

我檢查了jsp頁面先生....所有的大括號都正確終止......並且該jsp文件只有54行，但顯示在第205行的java文件中的錯誤.... !!!! – 2011-05-07 09:55:38
