I have a file which apparently contains serialized structures. The first 26 bytes contain the string "java.util.HashMap", so I am sure that this file holds serialized data.

Is there is nice tool maybe with a simple UI, where I can show the structured data?

I googled for it for a while, but I didn't find any proper resources. It should run preferred on Windows. Linux would be fine too but is overhead for me.

There is tool from Google called "jdeserialize":

jdeserialize is a library that interprets Java serialized objects -- the data generated by an ObjectOutputStream. It also comes with a command-line tool that can generate compilable class declarations, extract block data, and print textual representations of instance values.

There is also a Java library called "Serialysis", that can be used to generate human-readable output of a serialized object, like so:

SEntity sint = SerialScan.examine(new Integer(5));

...produces this output:

SObject(java.lang.Integer) {
  value = Prim(int){5}

Since both projects are written in Java, you can use them in both Windows and Linux.
