attach source emanate eclipse

in obscure (ganymede) i'm debugging formula uses apache commons httpclient step httpclient code. i've downloaded source formula attempted insert normal heed (ctrl-click slight name insert source button). i've attempted insert both outmost record outmost folder success. i've trustworthy source before issues now step hibernate source formula successfully.

i've even attempted modifying .classpath record directly supplement sourcepath manually. still luck. lovely project, doing purify build, shutting re-opening obscure solve issue. frustratingly, obscure provides blunder message; only does insert source.

here entries .claspath:

<!-- hibernate. works -->
<classpathentry kind="lib" path="/myeap/earcontent/app-inf/lib/hibernate.jar" sourcepath="d:/data/download/hibernate-3.2.2.ga/hibernate-3.2/src"/>

<!-- commons httpclient. insert -->
<classpathentry kind="lib" path="/myeap/earcontent/app-inf/lib/commons-httpclient.jar" sourcepath="d:/data/download/commons-httpclient-3.1/src/java"/>

i've attempted changing route d:/data/download/commons-httpclient-3.1/src does work either.

the office structure is:

d
  data
    download
      commons-httpclient-3.1
        src
          java
            org

                commons
                  httpclient
                    autocloseinputstream.java
                    ... (and forth)
