i have checked my property file, class, everything looks fine,,
why this exception occur and how can i solve it???

thanx in advance,,,,
:)

Looks like there is a descrepency in the type definition for temp.Temporary.id. Post your code and mappings but I suspect you have declared the wrong type somewwhere or it's a null when it shouldn't be...

i have declared id type String .
in database it is varchar(128).
and in mapping file it is

<id
name="id"
column="id"
type="java.lang.String"
>
</id>



thanx for giving ur valuable time.

Can you post the code of your class ?

here is my class code..........

public class Temporary {
private String id = null;

private String tempId = null;

private int count = 0;

public Temporary() {
}

public void incrementCount() {
count++;
}

public void incrementCount(int iCount) {
count = count + iCount;
}

public void decrementCount() {
count--;
}

public int getCount() {
return count;
}

public void setCount(int count) {
this.count = count;
}

public void update() {

}

public String getId() {
return id;
}

public void setId(String id) {
this.id = id;
}

public String getTempId() {
return tempId;
}

public void setTempId(String tempId) {
if (tempId != null) {
if (tempId.equals("")) {
tempId = null;
}
}
this.tempId = tempId;

}

}

This is not a setter in the true sense - if I pass in "" it doesn not get set to "" and thus it has more logic...

It's just a hunch and I have no proper explaination, but if you change this to be a proper setter, does it work?

thanx
but it doesn't work.

tempId is just a field that can be null.
id is primary key.

can u tell me when this

org.hibernate.PropertyAccessException: IllegalArgumentException occurred calling getter of

exception occurs.

i m using hibernate's saveOrUpdate() method to save data.

You can set a breakpoint in:

and see what happens.
