Using external library jar

Hi everyone,
I am working on a J2EE 1.3 project. I have a external library jar file at, for example, /myproject/lib. My EAR has to access that external library jar. Moreover, the library jar is not self-contained. It has to use the class that stored in the EAR file.
I have seen a lot of articles that talking about using Class-Path attribute in the manifest file but that seem not work in my case.
Could any one have any idea how I can call a external library jar file which is not self-contained under J2EE 1.3 spec? Thank you very much.
Jacky

In J2EE 1.3 there was no portable mechanism for extending the appserver-wide classpath of
a J2EE appserver. However, most appserver's have some way of doing it. You'll need to
consult the documentation of whatever implementation you're using.
However, in that case you cannot have code in the appserver classpath with dependencies on
code in a specific J2EE application. The dependency can only occur in the other direction.

Using External Library in a DC problem (SP16)

Hi,
I've been trying to get the example that Valery is outlining in his <a href="/people/valery.silaev/blog/2005/09/14/a-bit-of-impractical-scripting-for-web-dynpro">Blog</a>.
I've done it exactly as Valery says, but I can't get it to work. I create the External Library DC, add the jar to Public Part (purpose Assembly) and build. Builds ok.
I then proceed to creating the J2EE Library. It is created ok. I then add the External Lib I just created to Used DCs. This goes ok. I build the DC. There are warnings:
Warning: Warning: Source folder does not exist, will be ignored: server
Plugin initialized in 0.03 seconds
Warning: No runtime information available for development component type External Library (sap.com), cannot validate runtime dependency.
And:

       [cda] WARNING: Ignoring invalid runtime dependency on js/jars (orion.com), type External Library
I've tried nearly every combination of Dependency Types When adding the used DC to J2EE DC. The jar never ends up in the SDA file in gen\default\deploy or jar in gen\default\public. I only get different types of warnings.
Here is the whole build.log:

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

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.

How to use external libraries jar files in the composite application?

Hi,
I have some external jars files (which consists of java classes) that I would like to use in my composite application.
I have created a DC with type as external library for the jars. However, I don't know how to specify the DC to be used in my caf application.
Can anyone help?
Thanks.
Regards,
Fui Voon

Hi,
My jar files consists only java classes and a manifest.mf. The files are compiled using jdk 1.4.2-b28. Will this be any issue?
It seems that if I ignore the error and continue step 7 which is to do deployment of the ear, the error given is
Cannot update it.
Caused by: com.sap.engine.library.bytecode.cf.CFException: Invalid constant pool tag, 60 at index 41.
Does anyone know what that mean?
Is there any sample that teach how to deploy external libraries as bundled library?
Thanks.

How to use external library in EAR deployed onto J2EE engine

For certain reasons some classes in .jar file in operation system level should be used in the EAR project I've deployed onto J2EE Engine.
Can some one tell me what steps I should perform to acheive this?

hey there,
Think im already late for this... but it may be useful to someone who reads this forum later.
I am struggling with exactly the same problem for the past more than 24
odd hours now. The sad part - Im sure I have seen this being done in a
matter of a few minutes when my team mate had an older version on NWDS.
(I am currently using SP16 NWDS). May be this indeed is a bug that SAP
needs to fix in its SP16 NWDS release.
I need to use the HSSF POI libraries for my webdynpro components and
have been trying ALL possible options given out here on SDN. To mention a
few, I have tried -
1) Jarrod's method of making a Java DC and then declaring a usage
dependency for it inside a J2EE Server (library) DC. It didnt work... it
gave me a warning that an illegal reference has been made to the runtime
public part. And the final SDA file generated in the J2EE server
component DC DIDNOT contain the jar files that I had added to the public part
of the Java DC. On investigating further, I found that there were NO
entities present in BOTH the public parts of the Java DC, even though the
folder actually contained all the required .jar files.
2) Creating an External Library DC, adding the JAR files to the
'libraries' folder. Creating two public parts, one for assembly and the second
for compilation. Then adding this DC as a 'Used DC' into a J2EE Server
(library) DC. Yet, the .sda file that is created on building the J2ee
Server (library) DC DOESNOT contain the JAR files.
3) Creating an external library DC, adding the JAR files to the
'libraries' folder. Creating two public parts, one for assembly and the second
for compilation. Then adding this DC as a 'Used DC' into a webdynpro
DC. On building this webdynpro DC, the .ear file DOESNOT contain the JAR
files.
4) Directly adding the JAR files to my own webdynpro component in the
'src/packages' folder. This didnt work because on rebuilding the
project, the JAR files get deleted on their own.
5) Renaming my .JAR files to .ZIP, extracting the entire package
structure into folders, copy pasting this entire folder structure along with
its .class files into the src/packages folder. On rebuilding, the NWDS
deletes these folders and files on its own / behaves erratically. Also
copy pasted these .class files along with the proper package structure
into the '/bin' directory of my webdynpro application, but it still
didnt work.
The only thing that I have to try yet is to shift to SP10 of NWDS,
build this external library project and get the required JAR files put on
the wendynpro server. After that I might choose to get back onto the
SP16 version and hopefully continue productive work... !

Navneet.

Using external Library like iText

Hi everyone, first of all i would like to thank all you guys because this forum help me so much, i´m new to webdynpro and i´m facing this problem, (this is my first post) . . . all i want to do is to "deploy new archive and run" and see my app running.
I ´m using the iText .jar in my DC Webdynpro project, i followed this blogs but to me is very confusing because it seems that are to many ways to do that, but nothing results to me.
/people/bala.krishnan2/blog/2006/09/25/bid-adieu-to-bots--using-captchas
/people/valery.silaev/blog/2005/09/14/a-bit-of-impractical-scripting-for-web-dynpro
this are the two main solutions i tried.
1.- Create DC Library
2.- add .jar to libraries folder
3.- add to public part (the two ways, assembly and the other one)
4.- build
4.- Create J2EE library DC
5.- Add to Used DC the two public parts of the DC Library
6.- Build & Deploy
7.- I don't see any .jar in my deploy folder
8.- I see the new library in Visual Admin
9.- Add to Used DC of my DC Webdynpro the j2EE public part
10.- I cant deploy and run my app
1.- Create DC Library
2.- add to public part the assembly and the other one
3.- build
3.- Add to used DC of my webdynpro app , the public parts of the DC library
4.- I have the hints, the class definitions but when i click deploy new archive and run
the deploy stops with errors.
i really want to know what is the problem behind this because i only try all the blogs solutions but with no knowledge behind, and i´m expecting some results following the solutions like a recipe.

Hi ,
To user iText .jar in the webdynpro java project, you need to do the following steps :
1.- Create a project of type external DC Library.
2 - add iText.jar to libraries folder.
3.- create new public part of type "Compilation" by selecting the option 'Provides an API for developing/compiling other DCs' and the compilation
create a new public part of type 'Assembly' by selecting the option 'Can be packaged into other build results (e.g. SDAs)'.
4.- Then navifate to the "navigation perspective" and expand the External DC project and navigate
      to folder "def" and open the files with .pp ext. Then add the following piece of code in the "entities"    tag in both the files.
             <entity>
               <name>itext.jar</name>
               <package></package>
               <caption>itext.jar</caption>
               <description></description>
               <entity-type>Archive</entity-type>
               <entity-sub-type>Java Library</entity-sub-type>
          </entity>
5.- Then build the project and release the activity.
6.- Add to used DC of my webdynpro app -
Choose 'DC Metadata' under your WD DC and navigate to 'DC Definition' --> 'Used DCs'. Right click 'Used DCs' to add the DC usage relations. In the 'Add Dependency' wizard, choose 'Local Development' --> 'My Components' --> Used DC --> 'Public Parts'. Select both the pulic parts ExternalLibCompilation and ExternalLibAssembly and check the dependency type 'Build Time' for ExternalLibCompilation, and "Build Time & Run Time" for ExternalLibAssembly and then click 'Finish'.
7.- Finally, 'Build' the WD DC, so that all the declared dependency relationships gets well established. Thus far we've seen the approach for solving the problems related to the usage of External Library DCs.
Hope the above mentioned process helps you to solve the prob.
Thanks

Problem using External Library DC

Hello,
First of all, I'm a java programmer kind of new to NWDI. I'm working on a Java DC that's meant to send e-mails which of course uses the JavaMail API, so I understand I have to add to my SC another DC of type External Library that contains the jar files I need. Here is where it all falls apart. I have followed step by step several possible solutions to this and still gettin' the "import cannot be resolved" error message in my Java Perspective. The procedure I'm using is the one described in this thread:
Re: External Library DC question
Can anyone help me out with this? I'm using NWDS 7.0.14
Thanks in advance...

HI,
That post was to big. so without reading it im posting.
1 create a library DC.
2.Add the jar files in it.
3. create a public part of type API and SDA.(use SDA if you want to deploy it with the project(just like an add external jar file) or use API part (if you want to use it as add jar file option))
4. use that public part in you DC.
5. use add jar option in your build path.
if you have done these an having an error please tell me at what step you have a problem

Debugging in "strict mode" while using external library assets

Hi everyone. A new ActionScript-3 user here with a question on strict mode.
   I have multiple Flash pages which use the same art assets. To support modularity and possibly decrease total download time, I have implemented this by placing the shared assets into the library of a shared .swf file (the other .swf files all load this shared .swf file). The shared .swf contains ActionScript routines to place instances of the assets onto the stage and to perform other common functionality.
   A drawback to this strategy is that, correct me if I'm wrong, "strict mode" can not be used to debug calls to functions which exist in external .swf files. That is, if the parent .swf makes a call to a function which is defined within an externally loaded .swf, that function call will be reported as an error in strict-mode because Flash is unaware of the contents of an external .swf at compile time (though it is aware at run-time.)
   My understanding is that shared code can be compiled under strict-mode if the shared code exists purely as an external .as file, not as an external .swf file. However, again please correct me if I'm wrong, art assets which are shared at run-time must exist in an external .swf file. Therefore, by my understanding, if run-time shared assets are desired, then strict mode will not properly compile the projects.
   Is my understanding correct?
   Thanks for any help,
     - Rashid

      Posting an update.
      I have since found a way to compile in strict mode a project which loads an external .swf and acesses its functions. This external swf is able to have a library of its own which is accessed in the external swf's own ActionScript.
      Unfortunately, the solution I have found increases the size of the project's compiled swf. If anyone knows of a way to solve this problem without increasing swf size, I would be quite grateful if you were to share your knowledge.
      Posted below is the solution I am aware of, which increases file size. In these steps, “main project” refers to the top-level Flash project which is attempting to load other swf's. “External project” refers to an swf which is to be loaded by the main project.
1) Publish the external projects as swc files. “Swc” is a class file, and is to be accessed by the main project when debugging under strict mode. The .swc presumably contains information about external project's library items which are to be exported for ActionScript.
      To create an .swc file, head to “File->Publish Settings...->Flash”. Check the “Export SWC” box.
2) In the main project, add the external projects' .swc files to the external library path. This is found in, “File->Publish Settings...->Flash->Settings->External library path”. Either individual swc files can be added here (via the SWC file button) or the name of the directory where they reside (via the Path button). Both approaches should work.
3) Somewhere in the main project's ActionScript, the external project is likely being loaded via a line of code similar to myLoaderObject.load( myURLRequest ). For this new approach, it is now necessary to make use of the second parameter to load(), the loader context. Here's the new line of code:
myLoaderObject.load( myURLRequest, new LoaderContext( false, ApplicationDomain.currentDomain ) );
      If the LoaderContext parameter is NOT passed, then Flash unfortunately shall not report this as an error. Instead, you may observe strange behavior when the external swf attempts to use its exported library items.
4) If the main project's code refers to the external project's class by name, then that class will need to be “import”ed into the main project's code. Without this, the compiler will complain about not recognizing the class.
5) In the main project, edit “File->Publish Settings...->Flash->Settings->Source path”. Add the path to the external project's .as class file. Without this, the main project shall give a run-time error of not being able to find the external class.
   This final step, 5, is what increases the size of the main project's swf. I have a project with a few nested .swf loads, and the main project's swf increased by about 10Kb when using this solution.
      This does not seem proper. That is, one would desire the sizes of the final swf's to remain unchanged regardless of the level of compile-time error reporting. If my interpretation of an .swc class file is correct, then it seems logical to presume that step 5 above should not even be necessary, because the class information is given to the compiler/debugger through the .swc.
   Anyone know what I am doing wrong, or otherwise how to get around this problem?
   Thanks bunches.

Using external util JAR from Session EJB

I have a Stateless Session EJB that uses some classes packaged in a utility jar. How do I package the EJB jar with this util jar, and get the app server to recognize this utility jar? including a /lib dir with the utils jar in it, like you would with a WAR, doesn't work.
I've temporarily got this to work by modifying the startup scripts for my app server to ensure my jar is included in the -classpath arg, but this cannot be the intended way. (cannot find details on this in the tutorial).
Thanks in advance!

Well, the answer depends a lot on which appserver you're using, because it obviously depends on how the vendor implemented the containers' ClassLoaders. What usually works is dependent upon a portion of the JVM spec regarding the MANIFEST.MF file. If you package your ejb.jar and library.jar in an .ear file, you can put the following in the ejb.jar MANIFEST.MF:
ClassPath: library.jarNote that there must be at least one blank line at the end of the MANIFEST.MF file.
This works on WebLogic, but, as an example, JBoss uses a single ClassLoader, so I'm not entirely sure how you'd go about the same thing there.
And you're quite right - putting it in the JVM ClassPath is not a good idea...

Problem with external library DC

Hi,
I am working on NWDS Version: 7.02.06.
I am trying to use JXL jars in my DC and have used the blog /people/bertram.ganz/blog/2008/11/24/how-to-use-external-jar-files-in-web-dynpro-development-components to achieve this.
My problem comes at the last step. When I add the Library refernce in my WD DC, i give sap.com~hkjecomp. Sap.com is my vendor and hkjecomp is the JEE (Library type DC) wrapping the External lib DC.
When I deploy the WD DC, it deployed with warnings and a cluster wide exception :
Aug 5, 2011 5:41:12 PM /userOut/deploy (com.sap.ide.eclipse.sdm.threading.DeployThreadManager) [Thread[Deploy Thread,5,main]] WARNING:

Deployment exception : Got problems during deployment
While trying to add the Library reference, I have also tried with sap.com/hkjecomp.
I have asked the basis guys to find out if the JEE application is running or not, but meanwhile can someone suggest if anything else could have gone wrong.
Thanks,
HImanshu

How to use a jar from a external library DC Project?

I followed the steps of how to create DC, External Library Project, which contains the jar I want.
I understood that this type of project can't be deployed so I build and deployed other DC Project from the type J2EE server component Library and added it to it's public part. What do I do next, to actually use the jar and it's imports?
Thank you,
Meytal.

Please let me know how to fix this issue.
Thanks in advance.
Thanks and Regards,

Rashmi,
Following observations from the error log:
a) DC temp/jxljar1 is External Library DC; if I am not wrong.
b) Once the J2EE DC is deployed; automatically jxljar1 should also be loaded in server
Coming to the issue you are facing; plz let us know following points:
a) Are you trying to transport the content from one landscape to the other i.e. development to QA?
b) During what operation and in which unit(DTR/CMS/CBS);you are facing the issue?
Regards,
Ganga
