Problem:
How can i show the name of the object selected in the drop down box als Titel?
I would to display the name of the selected object als Titel.
Thank you for your inputs.

Your treating the object like it has a literal value.
E.g. you can treat a varchar2 as a literal value as it contains exactly that:
declare
s varchar2(20) := 'Hello World';
cmd varchar2(100);
begin
cmd := 'DBMS_OUTPUT.put_line('''||s||''');';
DBMS_OUTPUT.put_line( cmd );
end;
Result: DBMS_OUTPUT.put_line('Hello World');
Now what exactly do you expect the compiler to put as a literal value when you change variable s in this sample code to a complex type that does not contain just a single literal value?
To fix your code, try the following approach:
declare
cmd varchar2(200);
begin
cmd :=
'declare
s TString;
begin
s := new TString( ''str1'', ''str2'' ):
TestPackage.Process1( s );
end;';
DBMS_OUTPUT.put_line( s );
end;
Result:    declare
          s  TString;
     begin
          s := new TString( 'str1', 'str2' ):
          TestPackage.Process1( s );
     end;As for using dynamic SQL properly, consider using bind variables (which also support Oracle classes/advance data types). The following code illustrates:
SQL> create or replace type TString is table of varchar2(4000);
2 /
Type created.
SQL>
SQL> create or replace procedure ShowString( s TString ) is
2 begin
3 for i in 1..s.Count
4 loop
5 DBMS_OUTPUT.put_line( s(i) );
6 end loop;
7 end;
8 /
Procedure created.
SQL> exec ShowString( TString('1','2') )

7 execute immediate cmd using s;
