      I know that quite a few people have been discussing the issue of passing hashes from SOAP::Lite, but I have
      not been able to find an answer to my question, hence my posting.
      I have written a SOAP cgi script which performs search and returns an array of hashes as the results (Since I
      come from a directory background, I wanted to mimic the LDIF format when returning the data). Of course,
      my SOAP::Lite client nearly worked the first time around. However, things got more difficult when I started
      testing with Java. Below is the trace of SOAP query and response and my server scripts. I can also provide
      the Java code if needed. Any help is appreciated. Also, from a miore general point of view, I would like to know
      what strategies other people have adopted to deal with such cases. After all, if SOAP is going to be the
      transport of the future, I am sure that many languages will have to be able to exchange complex data

      Here is the trace:
