Hi,
Apparently what I thought was a clear response, you did not find so. I'll
try again.
Here's your code annotated.
private ProjectInfoHome projectinfohome;
private ProjectInfo projectinfo;
public ProjectInfoJB getProjectInfoJB(int projectid) throws
RemoteException, ICantFindItException {
//to avoid spurious results from reuse of session bean instances,
always initialize your variables.
projectinfo = null;
try{
projectinfo = projectinfohome.findByPrimaryKey(new
ProjectInfoPK(projectid));
}
catch(FinderException fe){
//If you get here, you know for sure the bean you are looking for doesn't
exist.
// Don't just ignore it, figure out what you want to do and do it;
throw new ICantFindItException();
}
//with the initialization above, if the find failed, and you ignore the
exception, you will at least get a null pointer exception, better than the
wrong answer.
return projectinfo.getProjectInfoJB(); -->get value object
}
public ProjectInfoJB getProjectInfoJB() throws RemoteException{
//where is projectinfojb coming from? normally you would create a new
object to hand out.
//If you already handed this one out to someone, and modify it when the
session bean is reused,
//the guy who got the reference first is going to get the new values...not
what you want.
ProjectInfoJB projectinfojb = new ProjectInfoJB(); //get a new one
to return.
projectinfojb.setAgreementdate(this.agreementdate);
projectinfojb.setClient(this.client);
projectinfojb.setCommencementdate(this.commencementdate);
projectinfojb.setComments(this.comments);
projectinfojb.setCompanyid(this.companyid);
projectinfojb.setCompletedate(this.completedate);
projectinfojb.setContractor(this.contractor);
projectinfojb.setContractorperiod(this.contractorperiod);
projectinfojb.setContractvalue(this.contractvalue);
projectinfojb.setCountry(this.country);
projectinfojb.setInchargedp(this.inchargedp);
projectinfojb.setInchargeperson(this.inchargeperson);
projectinfojb.setOthersconsultant(this.othersconsultant);
projectinfojb.setProjectid(this.projectid);
projectinfojb.setProjectname(this.projectname);
projectinfojb.setProjectno(this.projectno);
projectinfojb.setProjecttype(this.projecttype);
projectinfojb.setServicescope(this.servicescope);
projectinfojb.setStatus(this.status);
return projectinfojb;
}
