Re: jdk 1.5 question

thank you for you patience for non java programmer like me who is more of an
administrator then programmer nowadays..

I definitely should study more on serilazation. I read the article you gave
me. Thank you.

Before reading your article, I failed to find readobject as part of HashMap
or its ancestor. consequently, I took an example from google search to try
deserialize hashmap when the corresponsding object file is found for my
class in teh constructor .

Actually I am surprised that the compiler asked me for the serialVersionUID.
All Idid was added my custom classs of
package regextest;

/**
 *
 * @author g2
 */
public class RegexRecord {
    String Name, Regex, Remark, Option, Groups;
    Boolean bTested;

    /** Creates a new instance of RegexRecord */
    public RegexRecord() {
    }

}

so I can declare in my RegexTest.java
    HashMap<String, RegexRecord> myRegexHolder;

......

   String myRegexHolder = strHomeFolder + ".RegeextTest_RegexHolder.ser"

and in the constructor to determine if I should create form scratch an empty
myRegexHolder or if the corresponding serilized object is found for teh
user, deserialize:
    if ( (new java.io.File(strRegexHolderObjFSpec)).exists()) {
            // restore myRegexHolder
            boolean bFailed = false;
            try {
                // read and deserialize the blob
                FileInputStream fileIn = new
FileInputStream(strRegexHolderObjFSpec);
                ObjectInputStream inStream = new ObjectInputStream(fileIn);
                myRegexHolder = (HashMap<String, regextest.RegexRecord>)
inStream.readObject();
            } catch (ClassNotFoundException ex) {
                setStatus("Exception in deSerializing myRegexHolder: " +
ex.getMessage());
                ex.printStackTrace();
                bFailed = true;
            } catch (IOException ex) {
                setStatus("Exception in deSerializing myRegexHolder - IO
error: " + ex.getMessage());
                ex.printStackTrace();
                bFailed = true;
            }

I thought I was using the java.util.hashMap

but I guess I missused the javaio.inStream.readObject
.....\RegexTest\src\regextest\RegexTest.java:55: warning: [unchecked]
unchecked cast
found : java.lang.Object
required: java.util.HashMap<java.lang.String,regextest.RegexRecord>
                myRegexHolder = (HashMap<String, regextest.RegexRecord>)
inStream.readObject();
1 warning

So do I have do?
