Now I'd like for instance use methods of first mentioned object instance in second mentioned object.
I tried simply by sending object A instance as parameter to method of object B and call method but it seems it doesn't work....
If I understand what you're saying, it should work fine.
$A->methodfoo($B); # methodfoo will call $_[1]->methodbar();
Could you post a cut-down example of your code that still exhibits the problem? Also, please remember to read Writeup Formatting Tips.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
