Using 2jee library in a web module dc for an applet

hi,
i have create an external library dc, added some jars to it and wrapped that external library DC in a j2ee library dc.
the web module dc uses the j2ee library dc. after building the web module dc, the jars will not be a part of the war file.
the web module dc delivery an applet that reference the jars in the applat tag.
how i can resolve this problem in nwdi?
regards
h.rohr

hi marc,
i have create an external library with a compilation and an assembly public part. the j2ee server component library use (wrapped) external library and the web module dc use the j2ee server component library.
the public parts are visible in j2ee component library dc.
the web module dc use the dc reference to j2ee server component dc.
regards,

Using External Library in Mobile Web Dynpro Offline

Hi all,
i would like to use a jar in a Mobile Application for Handheld and i followed the steps from the wiki "Using External Library in Mobile Web Dynpro Offline" at
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/home/usingExternalLibraryinMobileWebDynpro+Offline
>How to use External Library in Mobile Web Dynpro Offline
>For using external jar in local deployment scenario, one can do following:
>1. In the dc where jar has to be used, add the jar as external jar classpath entry. It can be done via <dc> > (Right-click)> properties->Java Build Path->Select "add external jar".
>2. Do the programming using the jar.
>3. Shut down the mobile client.
>4. Copy the jar in the "lib" folder of mobile client installation.
>5. Deploy the application in the IDE.
>6. Run the application.
>In 5, the jar will not deployed and will be picked from the lib folder during 6.

Hi,
1) in Development Infrastructure Perspective -> rightklick in Navigator/Projekt Explorer -> new Project -> (Development Infrastructure) Development Component (DC).
NWDS generates Project Ressources e.g. the folder "libraries"
2) copy the jars to the "libraries" folder.
3) rightklick on the newly created Development Component (DC) -> Development Component -> Show In -> Development Properties -> go to the Tab "Public Parts",
in -> "Defined Public Parts" -> klick on Button "Add" -> give a name for "Public Part" -> at "Purpose" select "Compilation" -> Finish.
rightklick on the newly created Public Parts -> select "Manage Entities" and select the jars you want to use -> Next -> Finish.
4) switch to the Mobile Apps for Handhelds Perspective -> in Development Component select e.g. the Service Component or the UI Component ->
rightklick -> Development Component -> Show In -> Development Properties -> got to Tab "Dependencies" -> klick on Button "Add" -> under the Node MyComponents -> select the newly created Development Component with the Public Parts/jars (that was created in 1 - 3).
thats all, now you can deploy your application

Color changes between library/develop and web module

Hi there,
when changing between modules library/develop and web the color of the pictures changes. That means, pictures become darker and the red/orange colors become more intensive. Back to the library, everything is o.k. Webgaleries also change, but not normal exports.
Until yesterday everything worked wonderful, but then I updated from 3.0 to 3.3 and now there´s no more WISYWYG for the webgaleries!
Somedbody out ther who can help?
Thank´s, Tom

First up, Develop is the most current preview. Library previews depend on the preview settings and if they've been zoomed into recently. Web exports sRGB Jpegs and I believe the webcache files that are generated for preview are also. If you're using a Flash Gallery, then there is no colour management happening.
Is your monitor calibrated?

Using a class in a web module

I'm using netbeans and the web module template.
I'm pretty new to jsp, so please bare with me. I just want to be able to use a class in my jsp page.
I have 2 files:
WEB-INF/classes/Customer
index.jsp
in the Customer Class, i declare the package at the top:
package com.mycompany.data
public Class Customer {
in index.jsp, I want to use the Customer Class. I try like this:
<%@ page import="com.mycompany.data.*" %>
<%
Customer cust = new Customer();
%>
I keep getting an error in index.jsp on both the page directive and on the line where I declare and instantiate the Customer object.
Can someone inform me or point me to the right place to understand how to use a class in a .jsp?
Thanks

If the class Customer is in package com.mycompany.data
Then Customer.class should be a file in
web-inf/classes/com/mycompany/data/Customer.class
Apart from that it looks ok.
You might consider using a <jsp:useBean> tag instead of declaring customer in a scriptlet.
I'm very much a fan of minimum scriptlet code on a page.
Cheers,

JSP does not have visibility of java classes in simple Web Module Project

Dear Experts
I am developing what I thought would be a very simple Web Module Project for a simple webservice
to allow a user to logon to Netweaver Portal with a simple logon and password.
I have not done this in over 8 years, and am somewhat rusty.
The webservice is package in a .war and is deployed via an Enterprise Application project as a .ear.
The issue I am having is that I want to enhance the presentation of the webservice through the
provision of css and adding a couple of images. The "libraries" are visibile in the build path of web
module project.
At the top of my .jsp for logon form I want to import some java libraries in order
to get String webpath = componentRequest.getWebResourcePath()"/":
<%@ page session = "true"%>
<%@ page import = "com.sapportals.portal.prt.resource.IResource" %>
<%@ page import="com.sap.security.core.sapmimp.logon.SAPMLogonLogic" %>
<%@ page import="com.sap.security.core.sapmimp.logon.SAPMLogonCertLogic" %>
<%@ page import="com.sap.security.core.logonadmin.IAccessToLogic" %>
<%@ page import="com.sap.security.core.logonadmin.ComponentAccessToLogic" %>
<% IAccessToLogic proxy = new ComponentAccessToLogic (componentRequest, aResponse, IAccessToLogic.ENV_LOGONCOMPONENT);
final boolean inPortal = true;
String webpath = componentRequest.getWebResourcePath()"/";
// todo: find layout schema...
aResponse.addResource(componentRequest.getResource(IResource.CSS, "css/main2.css"));
%>
However, during runtime the libraries are unknown and I get the following SAPJ2 EE errors
indicating the methods etc are not known to the jsp:

Share files between web modules

As far as I understand, a web module corresponds to a single web page, possibly within a web application that contains multiple web modules (pages). So if my web application has two pages, they would each be a web module. For example,
http://www.myapp.com (home page = root module /)
http://www.myapp.com/contact (contact page = contact module /contact)
I put both of these modules in an ear file to create a web application. However, the root module contains some .js javascript files and a css file that I want to use in all of the modules of my application. Also, I would like to share some tag libraries between the modules (pages) in my applcation, each of which has its own web.xml file which defines the uri and location of the tags.
Is this possible, or do I need to put all of the pages in my site into one web module?

A web module is a web application. The entire bookstore example is one web module.
A Web module represents a Web application. A Web module is created by assembling servlets, JavaServer Pages (JSP) files, and static content such as Hypertext Markup Language (HTML) pages into a single deployable unit. Web modules are stored in Web archive (WAR) files, which are standard Java archive files.

Iphoto is still not relaunching despite using iphoto Library Manager

Hi, I have used iphoto Library Manager to relaunch lost photos for my iphoto. When i recovered it, it simply loaded with the grey icon and does nothing. I downloaded iphoto Library Manager and i can see that it has all my back-up files. when I clicked on all the options to rebuild, it simply loads again without great effect. am I being impatient? I left it for 5 hours today and still no result?!

Hi Old Toad, Its the '11 9.2.3 version.
I'm unable to tell you if I can import photos as apparently I'm not registered and have to purchase a code.
However, I have tried to rebuild using iphoto library manager - it shows me the last photos I did have, but loads the iphotos as if it were a brand new program - which means i CAN import photos from scratch.
I've clicked on 'default' and 'relaunch iphotos', but it just opens as if its a new program and giving me the intro.
Have you ever encountered this? how can the photos be recovered?
Thanks alot for your response.

Need help using WEB module in Lightroom 2 for .mac/mobile me accounts

Hello,
I need help in finding the Server path information for Lightroom 2. I am trying to use the Web module of Lightroom and build a website and instead of going through another hosting service, I want to use my Mobile ME account, can't I do that?
I have the user name and password obviously but what is the server path, protocol, path?
Help please!
Thanks
Ray

For those Mac Users using iWeb, MobileMe, and Lightroom 2, here are step-by-step instructions on how to create a web gallery in Lightroom, upload the gallery to MobileMe, and finally, how to link the uploaded files to the wesite you created in iWeb.
1. In the Lightroom Library module, create a collection of photos you want to display in your web gallery. For illustration purposes, we will call your collection Sunsets. Once created, it will be listed under Collections in the left panel of Lightroom.
2. Switch to the Lightroom Web module and select the Sunsets collection (from the panel on the left of the screen.)
3. Chose whichever template you like (from the list of Templates in the left panel).
4. Fine tune the appearance of the gallery using the controls in the right hand panel of Lightroom 2.
5. When you are satisfied with the gallery’s appearance, use your keyboard to type Command-S. That will save your template settings (give it a unique name when saving).
6. Open up Finder on your Mac. Inside your username folder, create a new folder… I'll call it Web Files. (You can choose any name you like, and locate the file anywhere on your Mac HD.) You have just created the folder username/Web Files.
7. Back in the Lightroom Web module, chose Export, at the bottom of the right panel, and export your gallery to the folder you just made (e.g. export to username/Web Files). By doing so, you will have created /username/Web Files/Sunsets.
8. Once again open Finder on your Mac. Go to /username/Web Files/Sunsets and you will see 3 files in the Sunsets folder: bin, index.html, and resources.
9. Open a second Finder window and in it, click on your iDisk icon. You will soon see all of the files on your iDisk.
10. In iDisk, click on the folder called /Web. You will now see the /Sites folder inside the /Web folder. I.e., /Web/Sites.
11. Drag the Sunsets file from your Mac HD to the /Sites folder on your iDisk. E.g, drag Sunsets from /username/Web Files/Sunsets on your Mac HD to the /Sites folder in iDisk /Web/Sites. The Sunsets folder (and the three files it contains) will now upload to your iDisk on MobileMe.
12. Open iWeb on your Mac. Add a new page to your website. Call it “Galleries,” or anything you like. (You can also use an existing page if you wish.)
13. On that “Galleries” web page (or on an existing web page), create a picture icon, or a word, or a symbol, or anything else that you will activate as a hyperlink to your iDisk web files - specifically, you will link it to the Sunsets folder you just uploaded to iDisk.
14. Activate the hyperlink in iWeb’s Inspector. In the URL box, type:
http://web.me.com/username/Sunsets (Don’t forget to substitute your name for “username” and the name of your gallery for “Sunsets.”)
15. Save your website in iWeb, and then publish your site.
You will NOT see your gallery in iWeb – you will see only the link to the gallery that you uploaded to iDisk.. To view your gallery, either make hyperlinks active, using the Inspector in iWeb and click on he link to the gallery, or visit your website on the internet. If you want to edit your gallery, you will have to do that in Lightroom… then repeat steps 7 – 11. You cannot edit your gallery in iWeb, but you can use iWeb to change the appearance of the link to your gallery, or to change it’s location within your website.

Library grid shortcut issues within web module

If I select any field within the site info dropdown and select something else (to de-select the text field), hitting "G" no longer takes me to the library grid. The shortcut works when I initially enter the web module, but if I select anything from any of the right panel's drop-down menus, the shortcut no longer works. Has anyone else experienced the similar issue? Using LR 1.3 & 10.5.1.

The shortcut isn't working even after hitting the escape key. I tried alternate screen modes and clicking various places around the screen, but to no avail. I tried one alternate test (unfortunately after the original post) and the issue seems to only affect the flash templates. If the issue actually affected others, I would think the updating of the dynamic information for presenting in LR was creating some loop with the flash module that prevented the shortcut key from working. But if the shortcut key works for others when working in a flash template after a dynamic field is selected and de-selected, it's obviously related to my setup (or user error as the case usually is).

How do I use the Web module to upload video to my website?

I'm using the Lightroom HTML gallery to upload my photos, fine and dandy, very happy with it. I also have some videos trimmed in Lightroom that I want incorporated into the gallery. This doesn't seem to be happening, instead I just get thumbnails. What/how do I incorporate my video clips into my web gallery? I moved over from jAlbum so I could have a simple one-tool workflow, so I'm really hoping that this is possible.

You can combine stills and video for output to h.264 (mp4 file) for example to upload to Youtube or Vimeo.
FTP upload will be subject to the limitations of your host. The web module within Lightroom creates all resources to link to the file index.html
The forthcoming LR6 is anticipated to have HTML5 galleries.

I want to use the Web module to publish to the a website... What kind of server do I need to be able to publish my website?

I want to use the Web module to publish to the a website... What kind of server do I need to be able to publish my website?

You don't need a server, you just need a web hosting package such as the ones from GoDaddy or many other hosts. You then send the web gallery directly from LR to your web space.
As you're asking such basic questions, it might be best if you read articles like this and see if a friend or colleague can get you started.

How can you develop photo galleries with multiple pages using the web module?

Going through the web module I can see there are many options for developing a web page with a single collection of photos. How can you develop a web site with multiple pages containing different categories of photos using the Lightroom web module?

This thread will give you several ideas.

Using External Library in Web Dynpro - Error

Hello,
I want to use an external library in a web dynpro. I use WAS 6.40 SP12.
1. I have created an dc web dynpro app
2. I have created an dc external library app
3. I have importet the jar to the external library
4. I have published the jar as public part
5. I have imported the public part to web dynpro
If I build the project I get no error. If I deploy an run the project then I get an error stacktrace:
java.lang.NoClassDefFoundError: com/sap/netweaver/bc/rf/util/uuid/UUID
NoClassDefFoundError - I think the jar-file was not deployed. What is wrong?
Greetings
Thomas

Hi THomas,
Please explain how you are adding the jars into the publicpart of the Libary DC.
You need to create 2 public parts .
1. Assembly
2. Compilation
You need to add your jar to above two public parts.
Then you need to add above two publicparts to your webdynpro application.
