Using external Library like iText

Question

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/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
