如果你要往类OracleJavaProc中添加一个相关的存储过程方法，是如何对其进行开发呢？以下的文章就是其正确的步骤的介绍，首先是把dropjava, 改程序，再是loadjava。以下就是详细内容的描述。

e.g.修改OracleJavaProc类内容如下：

importjava.sql.*; 
importoracle.jdbc.*; 
publicclassOracleJavaProc...{ 
Addasalgradetothedatabase. 
publicstaticvoidaddSalGrade(intgrade,intlosal,inthisal)...{ 
System.out.println("CreatingnewsalgradeforEMPLOYEE..."); 
try...{ 
Connectionconn= 
DriverManager.getConnection("jdbc:default:connection:"); 
Stringsql= 
"INSERTINTOsalgrade"+ 
"(GRADE,LOSAL,HISAL)"+ 
"VALUES(?,?,?)"; 
PreparedStatementpstmt=conn.prepareStatement(sql); 
pstmt.setInt(1,grade); 
pstmt.setInt(2,losal); 
pstmt.setInt(3,hisal); 
pstmt.executeUpdate(); 
pstmt.close(); 
} 
catch(SQLExceptione)...{ 
System.err.println("ERROR!AddingSalgrade:" 
+e.getMessage()); 
} 
} 
publicstaticintgetHiSal(intgrade) 
...{ 
try...{ 
Connectionconn= 
DriverManager.getConnection("jdbc:default:connection:"); 
Stringsql="SELECThisalFROMsalgradeWHEREgrade=?"; 
PreparedStatementpstmt=conn.prepareStatement(sql);pstmt.setInt(1,grade); 
ResultSetrset=pstmt.executeQuery(); 
intres=0; 
if(rset.next()) 
...{ 
res=rset.getInt(1); 
} 
rset.close(); 
returnres; 
} 
catch(SQLExceptione) 
...{ 
System.err.println("ERROR!QueryingSalgrade:" 
+e.getMessage()); 
return-1; 
} 
} 
}
