Hi experts,
I have a question about invoke “com.webMethods.portal.service.sql.DataManager.getConnection();” in main method, java.lang.NullPointerException occurs, and I want to know how to test this kind of class like “com.webMethods.portal.service.sql.DataManager.getConnection();”, It works fine when I deployed on server,but not in local testcase.
public final Map<String, String> getDBSelect() throws SQLException{
logger.info("???????");
Connection conn = null;
PreparedStatement ps = null;
ResultSet rs = null;
String sql = "SELECT * FROM RL_ATTACHMENT WHERE ATTACHMENTID=?";
Map<String, String> descMap = new LinkedHashMap<String, String>();
try {
conn = com.webmethods.portal.service.sql.DataManager.getConnection();
logger.info("conn:" + conn.toString());
System.out.println("conn:" + conn.toString());
ps = conn.prepareStatement(sql);
ps.setString(1, "123");
rs = ps.executeQuery();
while (rs.next()) {
String item = rs.getString(1).toUpperCase();
descMap.put(item, rs.getString(2));
logger.info(item + " = " + rs.getString(2));
System.out.println(item + " = " + rs.getString(2));
}
} catch (Exception e) {
logger.info(e.getMessage());
e.printStackTrace();
} finally {
rs.close();
ps.close();
conn.close();
}
descMap = Collections.synchronizedMap(descMap);
return descMap;
}
public static void main(String[] args) throws SQLException {
TestJavaBean testJavaBean = new TestJavaBean();
testJavaBean.getDBSelect();
}thanks in advance.
best regards,
felix
