Hi all!
i'm having a problem writing a custom datatype. I need this because and i need strings longer than 255 chars.
Also i don't need every string to be longer than 255 and simply changing the lava.lang.String mapping in standardjboss-cmp.xml doesn't make the work. That's why i have to write a custom data type.
What i don't know is what's the code that i have to implement in my class.
This is what i have wrote...however in the db row i get the signature of the class but not the value of the inner string.

import java.io.Serializable;
import java.io.ObjectStreamException;
import java.io.IOException;

public class LongString implements Serializable {

private String value = "";

public LongString() {
value="";
}
public LongString(String _initValue) {
value=_initValue;
}

private void writeObject(java.io.ObjectOutputStream out) throws IOException {
out.write(value.getBytes());
}

private void readObject(java.io.ObjectInputStream in) throws IOException, ClassNotFoundException {
value = "";
int b;
while ( (b = in.read()) != -1 ) {
value = value + (char) b;
}
}

public Object writeReplace() throws ObjectStreamException {
return value;
}
public Object readResolve() throws ObjectStreamException {
return value;
}


public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}

Please give me some advice!!!

Thanks in advance,
Davide
