XPages: Bootstrap File Input
Wed, Mar 26th 2014 5:16a   Sven Hasselbach
When using the default file upload control in a Bootstrap application, the default file upload button does not fit anymore to the design: To fix this issue, you can use a small jQuery plugin named Twitter Bootstrap File Input. When this plugin is added to your XPage, the button will look like this: To initialize the jQuery plugin, you have to call it with a selector which selects all DOM elements of type file: The description of the button can be changed by setting the title attr [read] Keywords: xpages application css java twitter

Quick-n-Dirty: Use “isDocEditable” in an old school Java Agent
Fri, Mar 14th 2014 4:40a   Sven Hasselbach
If you want to check if a document is editable, you can do this in an old school Java agent with the NAPI function isDocEditable provided by the XSPNative class. First you have to add the required JARs to your agent. Then, you have to call XSPNative.isDocEditable with the document you want to test: import lotus.domino.AgentBase; import lotus.domino.Database; import lotus.domino.Document; import lotus.domino.Session; import com.ibm.domino.napi.c.xsp.XSPNative; public class JavaAgent exte [read] Keywords: agent domino ibm lotus database java

XPages: Use async / defer option for external CSJS Script Libraries
Mon, Mar 10th 2014 6:56a   Sven Hasselbach
When adding CSJS libraries to your XPage, try to use the defer or the async option for a better user experience. When not using this options, the Page might be blocked during page load. Have a look at this example XPage which contains two external CSJS scripts (for demonstration purposes they are computed to get a remote script out of nowhere): Foo! Bar!

Today I wanted to add an attribute to the element of my XPage. My goal was to generate HTML code like this: After some testing I found a solution by overwriting the method encodeHtmlBodyStart.

XPages: Use a Method Binding as Converter

I accidentally found a way to add a method binding as a converter to a component, because I have added a managed bean as a converter directly in the source code. The DDE does not support this. If you go to the converter property of a component, you can only add one of the predefined converters: But you can go to the source and add a method binding to the option, in this case my bean which implements my converter functionality.

XPages: Optimized Partial Refreshs (2)
Fri, Mar 7th 2014 9:11a   Sven Hasselbach
With the Optimized Partial Refresh you can do a lot of nice things: If only a part of the form is sent to the server, only this part of the components in the JSF component tree will be processed. This means that only submitted values are applied, coverted and validated, which can result in less server usage and a better performance. Normally, if you have two required fields on you XPage and do a Partial Refresh, both fields will have a validation error: But with this technique, you can choose w [read] Keywords: ibm xpages dojo server xml

Quick-n-Dirty: Disable Validation for FileDownload control (2)

Because my old snippet does not work anymore for ND9 (the IBM changed the internal methods / objects) I had to create a new way to disable the validation of the FileDownload control. Now I have switched to a PhaseListener which waits for to any XspEventHandler and checks if this event handler is a child of the FileDownload control. If so, it skips the validation.

The undocumented NAPI for direct API calls in Java can easily used in normal agents. You just need to add two jar files to your java agent: lwpd.commons.jar lwpd.domino.napi.jar These files can be found in osgisharedeclipseplugins.

If you try to implement your own JSF Validator (by implementing javax.faces.validator.Validator), you will notice that you are unable to check for an empty value. The reason for this is rather simple: The method validate() is only called, if there is something to do. If the value is empty, there is nothing to do, that’s why nothing happens. But wait!

Mit XPages lässt sich ein Domino Server auf einfachste Weise lahm legen, da man über die Java Runtime beliebige Threads starten kann. Ein kleiner Button startet z.B. Notepad auf einem Windows Domino Server: Bei jedem Klick wird auf dem Domino Server einmal Notepad gestartet. Eine kleine Schleife, und auch ein großzügig dimensionierter Server geht in die Knie. Richtig übel wird es allerdings, wenn dieser Button geklickt wird: ACHTUNG! NICHT AUF PRODUKTIVEN SYSTEMEN AUSFÜHREN! [read] Keywords: domino notes nsd R4 xpages java javascript security server

Quick-n-Dirty: Locale setzen
Thu, Jan 5th 2012 5:12a   Sven Hasselbach
Um die Locale-Einstellung einer XPage programmatisch zu beeinflussen, kann die Methode setLocaleString bzw. setLocale des context-Objektes verwendet werden.  Damit die Änderungen übernommen wird, muss die Einstellung im BeforePageLoad gesetzt werden. So ändert ein… context.setLocaleString("zh-tw") … bzw. ein … context.setLocale(java.util.Locale.TAIWAN) …die Spracheinstellungen der generierten XPage. Sowohl das lang-Attribute der HTML-Seite als die Dojo-Konfiguration [read] Keywords: R6 dojo java javascript oracle

Security: Fernsteuerbare ViewDataSources
Fri, Dec 30th 2011 5:12a   Sven Hasselbach
Ist bei einer Datenbank die Option “Don’t allow URL open” gesetzt, ist sie nicht mehr im Web erreichbar. Mit den URL-Parametern databaseName und viewName lässt sich in Verbindung mit einer ViewDatasource dieser Schutzmechanismus jedoch aushebeln, und könnte ein Problem darstellen, wenn sich nur auf diese Option verlassen wurde. Als Beispiel dient hier eine lokales NAB, dass zu Demonstrationszwecken eine offene ACL hat (Default = Manager), bei dem die genannte Option jedoch ak [read] Keywords: acl ibm xpages javascript security xml

Domino Datasources On-the-Fly (3): ValueBinding & MethodBinding
Thu, Dec 29th 2011 6:12a   Sven Hasselbach
Das ist der dritte Teil der Serie “Domino Datasources On-the-Fly”. Der zweite Teil findet sich hier. Will man eine Wertezuweisung berechnen lassen, muss ein ValueBinding erstellt werden. Damit lässt sich dann z.B. der Formname eines DominoDocumentData-Objektes berechnen (zugegebenermaßen ein kleinwenig sinnlos, da man dies im Code sowieso erledigen könnte…). Hierfür existiert die Methode createValueBinding() der Application-Klasse, mit der ein neues ValueBinding-Objekt instanziert [read] Keywords: domino ibm xpages application javascript xml

Domino Datasources On-the-Fly (2): DominoDataView
Tue, Dec 27th 2011 8:11a   Sven Hasselbach
Das ist der zweite Teil der Serie “Domino Datasources On-the-Fly”. Der erste Teil findet sich hier. Views lassen sich ebenfalls programmatisch erstellen, allerdings muss mindestens der Name der Ansicht angegeben sein (und ausserdem muss die Ansicht existieren): var data = new com.ibm.xsp.model.domino.DominoViewData(); data.setVar("view1"); data.setViewName("All"); view.addData(data); Hier eine Beispiel-Implementierung in eine XPage (in der Datenbank muss die Ansicht “All [read] Keywords: domino ibm javascript xml

Domino Datasources On-the-Fly (1): Basics
Fri, Dec 23rd 2011 9:11a   Sven Hasselbach
Um eine Datasource On-the-Fly mittels SSJS zu erstellen, muss zum Einen ein neues Datasource-Objekt instanziert werden, zum Anderen die neue Datenquelle der XPage bekannt gegeben werden. Mit dem folgenden Code wird eine neue Document Datasource namens document1 erstellt und dann dem UIViewRoot-Element bekannt gemacht: var data = new com.ibm.xsp.model.domino.DominoDocumentData(); data.setVar("document1"); view.addData(data); Direkt nach der Anlage lässt sich die Datenquelle leider noch nicht [read] Keywords: domino ibm javascript xml

Quick-n-Dirty: Die HTTP-Session des Domino-Servers
Wed, Dec 14th 2011 2:11p   Sven Hasselbach
Um mit SSJS auf die HTTP-Session eines Domino-Servers zuzugreifen, ist nicht viel Code nötig: var exCon = facesContext.getExternalContext(); var sess = exCon.getRequest().getSession(); Dadurch lassen sich folgende Informationen ermitteln: getAttribute(Name:String) Liefert gebundenes Objekt des Attributes “Name” zurück getAttributeNames() Liefert die Namen aller Attribute als java.util.Enumeration zurück. getCreationTime() Zeit der Session-Erstellung, Millisekunden seit 1.1.1 [read] Keywords: domino java
