Question

I am having a problem handling date variables when I write to PostgreSQL using JSP forms. There has been some great tips but still can not get it right. I believe that I am passing a String from JSP to JAVA where it is a Date “setter” and “getter” writing to PSQL on a “date without time zone” column.

Here is parts of the JSP code related to the Date:

…. (some code) ….

SimpleDateFormat dateFormat = new SimpleDateFormat("dd/MM/yyyy HH:mm");

…. (mode code) ….

<%

if (action.equals("add")) {
  .
  .
  .

  newCampaign.setCampempDate(dateFormat.parse(request.getParameter("campemp")));

  newCampaign.add();
}  
%>

…. (more code) ….

               <input name="campemp" type="text" class="datePickBox" id="campemp"
 onBlur="javascript:checkFormat(this)" value="<%= defaultCampaign.getCampempDate() != null 
? dateFormat.format(defaultCampaign.getCampempDate()) : dateFormat.format(new 
java.util.Date()) %>" size=20>

…. (rest of code) ….

It is important to mention that on the input I am also using a calendar that passes the date with the correct format… this is another reason I am using a date field on the JSP side.

On the JAVA side:

…. (some code) ….

  private java.util.Date campemp= null; 

  private SimpleDateFormat userDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");

… (more code) … ++ Set and Get ++

public void setCampempDate(java.util.Date aCampemp) {    
    this.campemp= aCampemp;
  }


 public java.util.Date getCampempDate() {
    return this.campemp;  
  }

… (more code) … ++ LOAD ++

  public void load(ResultSet rs) throws SQLException {
   this.setId(rs.getLong("campkeydbid"));
    .
    .
  this.setCampempDate(rs.getDate("campemp"));
}

… (more code) … ++ WRITE TO DB ++

public boolean add() throws SQLException {
boolean success = false;
if (costingEnabled) {
  String call = "select " + getStoredProcedureMapper().getPrefix() + "_Add(?,?,?,?,?,?,?,?,?,?)";
  DataSource ds = PoolMan.findDataSource("mydatabase");
  Connection conn = null;
  try {
    conn = ds.getConnection();
    PreparedStatement pst = conn.prepareStatement(call);
      .
      .
    pst.setTimestamp(10, new Timestamp(this.getCampempDate().getTime())); 
 ResultSet rs = pst.executeQuery();
    if (rs.next()) {
      .
      .

… (more code) …

The “_Add” on the stored procedure is correct as it works if I “hardcode” the date on the pst.SetTimestamp

The error I am getting is the following:

org.apache.jasper.JasperException: Unable to convert string “04/07/2012 19:12” to class “java.util.Date” for attribute “campemp”: Property Editor not registered with the PropertyEditorManager

Any ideas on a workaround to parse the String to Date without affecting the DB date field and JSP input will be greatly appreciated.. thank you very much.

org.apache.jasper.JasperException: Unable to convert string “04/07/2012 19:12” to class “java.util.Date” for attribute “campemp”: Property Editor not registered with the PropertyEditorManager

You are passing Date in String in 04/07/2012 19:12 format so you need to use

dd/MM/yyyy HH:mm

From the code you posted, It seems you are using

private SimpleDateFormat userDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm");

as format in SimpleDateFormat
