WDException from J2EE Library ?

Hello,
I have a shared j2ee library implementing some java beans that follow the JavaBean, command bean pattern, business delegate and DTO's patterns.
I am using these from webdynpro component as an imported model (javabean model).
Now I want to follow SAP recommendation that bean exceptions (if any) shall be wrapped to WDException types (see WebDynpro Best Practices for Connecting To Java API's).
I have found no way to make this kind of exception visible from my J2EE Library. In fact class com.sap.tc.webdynpro.services.exceptions.WDException is only found in WebDynpro Runtime Service and not in any shared library. I am not willing to deploy in my library an additional copy of webdynproservices.jar because it is version related.
What is the correct way to achieve this?
I am on NW04 SP17.
Thanks in advance & Regards

Hello,
is their any solution for this problem?
I tried to use an own Bean-class from my J2EE-App,
but the JSP-Page returned "package <mypackage> does not exist".
The JSPDynPage is able to get the Bean.
same mechanism as shown above (SharingReference in portalapp.xml)
We are on SP17
Thanks in advance,
Thomas

How do I create a runtime library reference from a J2EE library DC?

I've created a J2EE library DC that references some classes in an already deployed library. The referenced jar file has been correctly deployed, as it's successfully used by some other components. I can build the DC, since I've created created a compile-time reference to the local copy of the target jar file.
Unfortunately, I can't figure out how to create a runtime reference from my J2EE library to the already deployed library - there just doesn't appear to be any place to put the reference, at least using a gui-based function in NWDS. Unlike WebDynpro, which has a 'references' configuration option, J2EE lib's don't appear to have anything similar.
Where/How can I do this?
BTW, the Visual Administrator function 'ClassLoader Viewer ' is a very handy tool for diagnosing ClassDefNotFoundError errors....

Hello Ken,
well it seems to be not a trivial thing.
1) Build your library DC.
2) Create folder "server" in root DC folder "_comp".
3) Extract provider.xml from generated SDA file to "server" folder.
4) Add references in provider.xml:
    <references>
      <reference type="library" strength="weak">
        sapxmltoolkit
      </reference>
      <reference type="library" strength="weak">
        com.sap.lcr.api.cimclient
      </reference>
      <reference type="service" strength="weak">
        tc~sec~securestorage~service
      </reference>
    </references>
5) Rebuild DC. Deploy.
6) Enjoy!

How to refer to J2EE library server component from a web service?

Hi,
I need help! I created a web service and it worked fine. However, I started having problems when I tried to use java classes from my deployable J2EE library server component. I got the NoClassDefFound error.
I tried to include the library DC in the Used DC list and put the reference of it in the web service deployment descriptor xml (application.xml and application-j2ee-engine.xml), but it did not work.
How do I refer and use java classes from my deployable J2EE library at run time from my web service application? What should I do?
Thanks,
Giavinh Pham

I would like to clarify more about the web service project. I created a Java DC project and converted it into a web service as the SAP manual instructions. It worked fine by itself, but I now want to use some of my classes that I deployed as a J2EE library server component.
It was compiled and built when I refer to my J2EE library server component DC in the UsedDC. It was deployed fine as well. However, it broke when I tested the web service calls. The class declarations and usage from the J2EE server component could not be found (NoClassDefFound error.)
I thought it was because I did not have an application-j2ee-engine.xml in my META-INF folder so I created one and referred to the library in xml as type library and reference 'strong'. I built and deployed again. It still did not work.
I examined the EAR and noticed that there were two parts of the EAR. One is the WSAR archive file that contains the META-INF folder from my project and other web service assemblies. The other part is the META-INF folder generated by the SAP NetWeaver IDE.
The strange thing was that SAP NetWeaver IDE generated an application-j2ee-engine.xml without any reference to my J2EE library server component. However, the nested application-j2ee-engine.xml in the WSAR archive file did contain the info.
Since I cannot control the application-j2ee-engine.xml generated by SAP NetWeaver IDE, what should I do? Is it the cause for my problem?
Please advice, anyone?

How to delete a J2EE library from the WAS?

Hello,
I have uploaded a J2EE library to the WAS, it can be found at the Admin tool under: Server->Libraries.
Suppose I don't need these library anymore and I would like to delete it. How do I do it?

Hi Roy,
It depends on which server you are asking for, for Netweaver 2004 and 2004s the easiest way to deploy\undeploy components would be via the SDM UI - launch it from \usr\sap\<sid>\<id>\SDM\program\RemoteGui .
There from the undeployment tab you should see your library, then click the select button, start undeployment and follow the instructions.
You may check the SDM documentation as well - it should be in a doc directory

Class in J2ee Library DC can't be found

Another Problem where I need your help.
I have a portal module Component, in this i have a class wich extends the AbstractPortalApplicatin and in the doContent i include a jsp wich i have written. In this JSP i need some logic. Cause the logic I need here is not only used by this component i want to outsource the class wich does the work.
So I created a java component in wich i wrote my class. Created 2 public parts, an api for build time and a sda public part.
After that i createt a j2ee libary dc, in wich I add the public sda part from the java component. The Api is only for Build Time of the portal Component.
In the portalapp.xml I created a private sharing reference to the j2ee library component. But the class cannot be resolved. I really don't know what i have done wrong....

I figured out that you need to move the folder over to the shared section or share every folder in you folder structure above the one you need to share!!!

How to set runtime references in J2EE library DC's

Hi,
I'm building an custom logon module. This is well described in
http://help.sap.com/saphelp_nw04/helpdata/en/46/3ce9402f3f8031e10000000a1550b0/content.htm
I created the following DC:
1. simple java project DC that contains the login module class
2. J2EE library DC that will act as the deployable component.
The part "Make reference to the Security Provider service of the J2EE Engine." (2b) is where i get stumped:
http://help.sap.com/saphelp_nw04/helpdata/en/bf/93d84072378031e10000000a1550b0/content.htm
The example adds the reference direct to the provider.xml. I don't have that option when I develop the library as a DC.
It seems that while EAR file DC's allow the adding of runtime library references via the application-j2ee.xml file, it seems that is not possible for J2EE library DCs.
Specifically, I'm trying to get the follwing entry into the provider.xml:
<references>
<reference provider-name="sap.com" strength="weak" type="interface">security_api</reference>
I saw one workaround in the SDN where they suggest to extract the provider.xml from the SDA and manually
add the references but this isn't really an option in our case.
Should I be deploying 'normal' EAR files in this case ? Have I overlooked something ?
thanks
Michael

Hi,
talk about overlooking the obvious . . . The appropriate public part is present in com.sap_SAP-JEE_1.
Adding that worked.

Where is "WebLogic J2EE Library "?

Hi, i want to extend Portal Administration Console, but when i do follow guide of oracle documentation, it seem not work.
Follow document : To copy a J2EE module to your web project:
1. In the Project Explorer, right-click the //web_project_name/WebLogic Deployment Descriptor > J2EE Libraries folder and then select Add Multiple.
2. In the Select WebLogic J2EE library, select the modules you need. The required administration console J2EE libraries are:
But i don't see where is WebLogic J2EE library. Can someone tell me where is it ? Thanks in advance and sorry for my bad English.
Best Regards,
Coy.

If you mean the folder 'library' like from the computer, the iphone doesn't have one directly. If you connect your iphone to your computer then, depending on what you want, you can probably do it via the computer or try downloading an app like iexplorer and you can access loads of hidden folders on your iphone. Hope this helps but sorry if it doesnt

Hi Sanghun,
The problem is that the provider.xml is generated basing on .dcdef content. in this case you can assign weak refrences to libraries only due unknown for me reason.
If you want to use hard reference to libraries do the folllowing:
1. Create "server" folder in your project folder.
2. copy the "provider.xml" file to this folder from generated sda(do not forget to rename invalid "strong" reference to weak in .dcdef before building)
3. change the the "weak" to "hard" in the copied "provider.xml" file.
4. Build the project and check that sda contains correct reference strengh.
Best regards,
Aliaksei

I have an apple iphone 4 that I want to download audio books from my library onto it. I cannot figure out how to do that. The iphone does not show up on my mac laptop as a connected device. Does this kind of download have to run through itunes? Thanks

I have an apple iphone 4 that I want to download audio books from my library onto. I cannot figure out how to do that. The iphone does not show up on my mac laptop as a connected device. Does this kind of download have to run through itunes? Thanks

Yes it is done through iTunes. The iPhone will never show up in Finder as a device. The following is general information on iTunes sync: http://support.apple.com/kb/HT1386 and the following is a previous discussion where the post by Andreas Junge helped others that had a problem syncing audiobooks: https://discussions.apple.com/message/20052732#20052732

Delete file from iTunes Library and Computer

I convert a lot of my own TV shows for playback on iPad/iPod touch. Once I have watched the show I delete it from my library.
It used to be that when I deleted from my library, I would get a message asking if I wanted to delete from library only or from library AND computer. It does not ask me this anymore.
I went into preferences and clicked on "reset all warnings" but that didn't fix the problem. Any tips on how to restore this functionality?

What I mean is I don't want an extra copy of the file made when I add something to my library. I already have the file where I want it.
I did try your suggestion, and just as I suspected, it made an extra copy in a different location on my computer, then when I deleted it, yes, it asked me if I wanted to move it to the recycle bin, but it only deleted the copy, not the original.
I'm marking your response as helpful, as I can use it as a workaround if I can't find a better solution, but I have never done it this way before. I've always had full control over which folders my shows were in, and only one copy. And when I've deleted, it has deleted the original file, not just a copy of it.

How do I move photos from one library to another?

I have moved my 34gig iphoto library from my MBP to an external drive. I have now created a second library on the MBP with the intention of keeping just a smaller selection of my photos in this ready to edit.
Is there an easy way of importing photos from the old library on the external drive to the new one? Do they link up in any way, or, will I need to export a selection from the old library to a new folder on the desktop and then import from there?

To move all the versions, metadata and photos from one Library to another use iPhoto Library Manager.
Exporting from one and then importing to another will not get all the metadata (Faces, for instance) nor will it get the versions.
Another way to achieve what you seem to want to do:
1. Quit iPhoto.
2. Copy the iPhoto Library from your Pictures Folder to the external drive.
Now you have two full copies of the Library. To choose between them: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
3. On the Internal Library, remove the pics you don't want with you all the time.
Now you have one full library on the external and another smaller sub-set on the Internal.
A couple of comments:
a. The external disk needs to be formatted Mac OS Extended (Journaled)
b: When you're removing the unwanted pics from the Internal Library you need to delete them in batches of about 100 or so. Trashing more at one time can cause problems with the database.

Error while deleting image from picture library

Facing issue in deleting pictures from picture library from a site collection created in SharePoint 2010 mode in SharePoint 2013. Though we can open the picture and delete it from 'Delete Item' from the ribbon, we cannot delete the pictures from Actions
-> Delete option.
Here is the exception
Level:Medium Category: General
Application error when access /_layouts/DeleteMu.aspx, Error=Object reference not set to an instance of an object.   at Microsoft.SharePoint.WebControls.DeltaPage.LoadPageStateFromPersistenceMedium()
at Microsoft.SharePoint.ApplicationPages.DeleteMultipleItemPage.<LoadPageStateFromPersistenceMedium>b__0()     at Microsoft.SharePoint.ApplicationPages.LoadViewStateHelper.LoadViewStateOrNull(Func`1 loadPageStateFunc)
at System.Web.UI.Page.LoadAllState()     at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Hi Shivayogi,
Whether you migrate SharePoint 2010 to SharePoint 2013, and kept in 2010 mode.
If yes, please create a new site collection, then test again, compare the result.
Whether other libraries could work correctly.
Whether this issue occurres for 2013 mode site collections.
Best Regards,
Wendy

I already have adobe digital editions on my mac pc and download books from the library to my android e-reader. Can I use the same digital editions on my ipad air, or do I need to load a different one onto my ipad?

When I try to sync music from itunes library to my ipod touch, it says it can't sync because the connection to the iPod was lost. Please help!

When I try syncing music from my library to my ipod, I get the message that it lost connection. My ipod is plugged in to the computer though. Does anyone know how to fix this?

How is your iPod configured to sync music? In other words, what options and configurations do you have enabled from under your iPod's Summary and Music tabs in iTunes?
Maybe have a look at this article as well to verify your iPod is set up for syncing music.

Please help! Deleting songs from itunes library & updating ipod

Must I keep all albums I wish to upload into my ipod on my computer? I have the ipod settings set to automatic and if I delete the album from the library (completely from my pc) the next time I connect my ipod the album gets deleted from the ipod.
I tried setting the ipod to manual but then I can't figure out how to update my ipod with the songs I want to add. It really doesn't make sense for me to have to fill up my hard drive with all of this music just to keep the songs on my ipod. I really hope someone can please tell me otherwise.

If it's on Manual update, you simply drag the songs from the library to the iPod in iTunes.
If you wan tot remove music, right click on it and select Clear. Do this with the iPod selected not a playlist on the iPod.
