Certain properties arent beiing set (JDK-Version difference 1.2.1 & 1.3.1)

Question

Hello alltogether
I'm extending a software which was once written on the JDK 1.2.1. For my extenstions i choosed to used the JDK 1.3.1. Now that i m done with my part, i remarked that the existing part of the webapplication doesnt run correctly on a server with JDK 1.3.1, and my extensions doesnt run on a server with JDK 1.2.1.
So what i m gonna do is, i have to make the existing system runnable on JDK 1.3.1, so that the whole system can be run on the server with JDK 1.3.1.
The problem i have with the existing version, is that the properties arent beeing set.
An example:
The request string is:172.16.1.38:8080/SupportSystem/issuelist.jsp?ident=3&command=closed
issuelist.jsp has uses the bean IssueBean and sets all its properties:
<jsp:useBean id="issueBean" scope="request" class="ch.msw.support.beans.IssueBean" />
<jsp:setProperty name="issueBean" property="*" />
IssueBean's property-setter method for the look like the follows:
public void setIdent(String newValue) {
  if(newValue != null) {
    try {
      id=Integer.parseInt(newValue);
    } catch (Exception e) {}
}the command-property and the properties which are part of my enhancements are always beiing set. But the strange thing is that i cant find a difference between the functioning ones and the ones who fail
My supposition is that the 2 JDK - versions (1.2.1 / 1.3.1) implement different JSP-specifications which are featuring a difference with the property-setter-calling.
I cant figure how i could solve the problem...
maybe you can :-)
Thanks in advance!!!

What you have should work so I don't have a quick fix, only suggestions on how to track down the problem.
Presumably you must have recompiled IssueBean to add the new properties, so the java version is irrelevant. Ident is just as much a 1.3.1 property as is command.
Is the getIdent() method defined correctly? It must be "public String getIdent()" If, say, you are returning an int then the getter/setter pair may not be recognized by jsp:setProperty.
Try temporarily adding a System.out.println statement to setIdent so you know when it is called. Retest. If it is not called, add an explicit call to your JSP.
Add code to your JSP to print out all parameters. This will show whether ident is being passed through.
Good luck.
