Sorry, for my sloppy answer. But I could not resist.

I do not have the numbers, how many Java developers left for other languages. And actually, I am not really interested in them.
Can only speak for myself. If I can choose, I prefere Scala over Java in meantime. I produce code, which is less error prone, then in Java. Mainly because of the usage of immutable data.

Hallo,

I took a short look at the example chapter of PostGIS and realized, Open Street Maps is not mentioned in the book. Is this becous of, they changed to PostgreSQL only during the last year, or is there an other reason for this?

Anyway, the book looks quiet interesting, and I would be happy to read a bit more in it ;)

Greets,
Andreas

Thanks a lot!

Works now like a charme

Found the problem

I initialized the select items with the enum values, but I should have used the string representation of them.

The solution is: public List<SelectItem> getBundeslaender() { log.debug("getBundesländer"); List<SelectItem> bundeslaender = new ArrayList<SelectItem>(); bundeslaender.add(new SelectItem("", "")); for (Bundesland bundesland : Bundesland.values()) { bundeslaender.add(new SelectItem(bundesland.name(), getResourceText( bundesland.name(), (Object[]) null))); } return bundeslaender; } public String getArbeitsgeberBundeslandInfo() { log.debug("getArbeitsgeberBundslandInfo()"); Bundesland bundesland = this.arbeitsgeber.getAddress().getBundesland(); return bundesland == null ? "" : bundesland.name(); } public void setArbeitsgeberBundeslandInfo(String arbeitsgeberBundeslandInfo) { log.debug("set Bundesland Arbeitsgeber: " + arbeitsgeberBundeslandInfo); this.arbeitsgeber.getAddress().setBundesland( Bundesland.valueOf(arbeitsgeberBundeslandInfo)); }

Maybe this helps somebody else.

I do not know a solution, but I have written a small phase listener, which logs the request parameters to the servers log.
import java.util.Map; import javax.faces.context.FacesContext; import javax.faces.event.PhaseEvent; import javax.faces.event.PhaseId; import javax.faces.event.PhaseListener; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; /** * PhaseListener that logs request parameters before restore view phase. */ public class ParameterPhaseListener implements PhaseListener { private static final long serialVersionUID = -7280164859565844793L; private static Log log = LogFactory.getLog(ParameterPhaseListener.class); @Override public void afterPhase(PhaseEvent event) { } @Override public void beforePhase(PhaseEvent event) { FacesContext fc = FacesContext.getCurrentInstance(); Map<String, String> map = fc.getExternalContext() .getRequestParameterMap(); for (String key : map.keySet()) { if ("j_password".equals(key)) { log.debug("Parameter: " + key + " = ********"); continue; } StringBuilder param = new StringBuilder(); param.append("Parameter: '"); param.append(key); param.append("' = '"); param.append(map.get(key)); param.append("'"); log.debug(param.toString()); } } @Override public PhaseId getPhaseId() { return PhaseId.APPLY_REQUEST_VALUES; } }


maybe you can see a difference?

Hi!

I know a very good starting point. It explains JSF 2.0 in conjunction with Spring and Orchestry (which extends JSF a bit, but very usefull!)
The downside for you may be: it's german
But maybe there is a translation. I don't know, sorry

The book: http://www.dpunkt.de/buecher/3095/javaserver-faces-2.0.html
The book online: http://jsfatwork.irian.at/semistatic/introduction.html

The online book also contains the link to an very good example application, which is build up during the whole book, which explains the concepts of JSF 2.0

If you miss some components, take a look at primefaces. Rich faces is not ready for JSF 2.0 up to now (well you can use the old version with some really painfoll limitations).

And no, I do not earn anything with this book. I only really liked it.
Maybe this helps some else, if it's not the right thing for you.

Very good as additional information source is the following book about XHTML & CSS:
http://jendryschik.de/wsdev/einfuehrung/

It tells you how to build accessible state of the art web sites.

I checked now. The translation to english: The selected value is invalid

I also added the translation to the original posting.

ups! if I remember correctly it stand's for: invalid value
I will check in my office tomorrow.

greets

Edit: fixed type. iPhone touchkeybordes 5 minutes before falling asleep can be tricky ;)

Hello,

I am relatively new to JSF 2.0 and struggle around with Validation in my case.

my Facelet:


<li> <h:outputLabel for="bundesland" >Bundesland <em><h:graphicImage alt="required" styleClass="stern" library="images" name="required-stern.gif" /></em> </h:outputLabel> <h:selectOneMenu id="bundesland" required="true" value="#{registrationBean.arbeitsgeberBundeslandInfo}"> <f:selectItems value="#{registrationBean.bundeslaender}" /> </h:selectOneMenu> <h:message styleClass="error_messages" for="bundesland" /> </li>

in my backing bean:
public RegistrationBean() { // combo boxen befüllen this.bundeslaender = new ArrayList<SelectItem>(); this.bundeslaender.add(new SelectItem("", "")); for (Bundesland bundesland : Bundesland.values()) { this.bundeslaender.add(new SelectItem(bundesland, getResourceText( bundesland.name(), (Object[]) null))); } } // combo boxen in registrierungs seiten private List<SelectItem> bundeslaender; public List<SelectItem> getBundeslaender() { System.err.println("Hole Bundesländer"); return bundeslaender; } public void setBundeslaender(List<SelectItem> bundeslaender) { System.err.println("Setze Bundesländer"); this.bundeslaender = bundeslaender; } public SelectItem getArbeitsgeberBundeslandInfo() { Bundesland bundesland = this.arbeitsgeber.getAddress().getBundesland(); String bundeslandKey = bundesland == null ? null : bundesland.name(); return bundeslandKey == null ? new SelectItem(null, "") : new SelectItem(bundeslandKey, getResourceText(bundeslandKey, (Object[]) null)); } public void setArbeitsgeberBundeslandInfo( SelectItem arbeitsgeberBundeslandInfo) { System.err.println("set Bundesland Arbeitsgeber: " + arbeitsgeberBundeslandInfo); this.arbeitsgeber.getAddress().setBundesland( Bundesland.valueOf((String) arbeitsgeberBundeslandInfo .getValue())); } public static String getResourceText(String key, Object... args) { String text; try { FacesContext ctx = FacesContext.getCurrentInstance(); Application app = ctx.getApplication(); ResourceBundle bundle = app.getResourceBundle(ctx, "rb"); text = bundle.getString(key); } catch (MissingResourceException e) { return "no entry for key: " + key; } if (args != null) text = MessageFormat.format(text, args); return text; }

the validation problem:


Translation to english: The selected value is invalid

Btw: Bundesland stands for one of 9 organizational areas within Austria. Arbeitsgeber means employee.
Sorry for this horrible language mixture.

Anybody any ideas? I am running out of them

thanks in advance,
Andi

Edit: fixed a typo and added a translation to the error message.
