          As we know, we can extract unexposed Property rules value from pzPVStream by using Obj-Open or Obj-List method in Activity steps, that is the only way we could operate binary data stored in pzPVStream.

          I don't know how Obj-Open and Obj-List work, how to read pzPVStream to get the unexposed property. Is there any general way to get the binary data form database? If the pzPVStream image data is standardized data format, if not, how the PegaSystems to write and read it.

          Can we read and write column value from pzPVStream by Java code directly out of PRPC? Any body who could provide any solution?

          PDN said, Rules XML stream is stored in BLOB. Generally, BLOB column is not encoded if we don't check "Encrypt BLOB?".
          Developer can read information by following: it is the way to read XML Stream from CLOB column.
          Reader reader = ResultSet.getCharacterStream();
          I try to use this method to write the stream into file, the content is always encode. I don't know what was wrong.

          If he doesn’t want the Obj- methods, he can always the public APIs to do so.
          There are many methods in “com.pega.pegarules.pub.database” package (check out the Database interface).

          Try to put public APIs into Java code, PegaRULS DB connection must be referred.
