The problem in this case was that you didn't understand the nuances of Java serialization. For instance, RTTI is written out as part of the serialization process, so attempting to read-into a different class (even with the same fields and code) causes an error. My recommendation would be to /not/ use Java's built-in serialization, and instead write your data out in a way that does not depend on a particular class's interpretation of the data. Just define a standard (binary, XML, whatever) and then read and write to that format. > But the fundament of the plan is reliable (vectorial search) and I am > interested in an up to date installation of tomcat and java.

If you're starting from scratch, get the latest and greatest Tomcat version, which is currently 6.0.29. This page has more information on the currently-supported versions of Tomcat: http://tomcat.apache.org/whichversion.html If you must stick with the 5.5.x line, you should upgrade to 5.5.31 after reading the changelog to see if anything might interfere with your webapp's functioning. As always, get Tomcat directly from the source: http://tomcat.apache.org/ Go to the "Download | Tomcat 6.0" page and get the latest version. All you need is the "core" package: choose whatever packaging makes sense for your environment. For a Java version, we always recommend running on Sun's JRE (or JDK if you prefer). The only currently-supported version is 1.6.something: to go java.sun.com and download whatever the most recent version is. Feel free to come back to this list if you have any problems installing or configuring Tomcat. Good luck, - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkyrkcUACgkQ9CaO5/Lv0PCM5gCgoDam11AZxLAiQGFBj/zk/ikL Q4UAn229pufQzRHOlgvQt86/TWag0cDI =5FB9 -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
