Re: Issue java.io.StreamCorruptedException

So I need to modify the generated class, right? Actually for clob field I have this situation:

public void setRequest(String request) {
    	writeProperty(REQUEST, request);
}

public String getRequest() {
    return (String)readProperty(REQUEST);
}

How to change it?
