Hi, here is a problem I have with the jdk1.1.7-v1a and jdk1.1.6-v5, glibc. I have a java program which is running fine, and I use jax (www.alphaworks.ibm.com) for post-optimization, which works fine, too, at least on my machine at work (pentium II 400, redhat 5.2). The program works fine on my home maching (pentium 133, redhat 5.1), too, but the optimized code does NOT run with appletviewer (same jdk!!), but on netscape. I get strange errors, ranging from "ExceptionInInitializer" to linking errors with libzip. Tracking down the problems it seems to be related to the unzipping of the jar file, which seems to produce incorrect data. I spent hours on that problem, and I still cannot figure out the difference between the two installations. Also, it looks like the libzip (contained in the lib directories of the jdk) does not seem to be used at all. Is there anybody out there who does know a little bit about the libzip-usage of the jdk, or did anybody experience similar errors related to jar/zip files? Thanks a lot, Ulli
