In this past, this error has been a classpath problem. Browsers and jview ship their own JVM. These JVMs are not as 'complete' as IBM's and Sun's JVM in the area of text conversion. Specifically, they don't ship EBCDIC to/from unicode conversion tables. (Except for performance) this does not matter to the Toolbox. If the JVM does not supply a conversion table, the Toolbox gets it from the AS/400. The problem is when classes.zip from a Sun/IBM JVM is in the PC's classpath when a browser or jview is started. When the jvm cannot find a conversion table in it's container of classes it starts searching the files in CLASSPATH. If classes.zip from a different JVM is in the classpath, it will find the table. The problem is now "JVM" classes are coming from two different places. Some are coming from the browser or jview, others are coming from IBM/Sun classes.zip. These two sets of classes are not compatible and you get an exception. I have some confidence that this is your problem. I just ran a Toolbox testcase using JView. If classpath points only to jt400.jar, the test works. If Sun/IBM classes.zip are added to the classpath, the test fails with the exception you report. Remove classes.zip and give it a try. David Wall AS/400 Toolbox for Java "Brad Grier" <email@example.com> on 10/21/99 10:12:41 AM Please respond to JAVA400-L@midrange.com To: JAVA400-L@midrange.com cc: Subject: Microsoft JVM and Toolbox (For David Wall?) When using Microsoft's JVM to run my application (via JVIEW), I get the following stack trace. I'm using the latest V4R2M0 of the Toolbox (October 1999 build). I know an earlier poster mentioned this problem in regard to applets and David Wall said the problem had been corrected. I'm using my own sign-on dialog to pass the user id and password information into the connection URL. For earlier releases of the Toolbox I found a dubious workaround with the help of a decompiler (and three new lines of code to the Toolbox ConvTable class). I'd rather not have to resort to this to get my application to work with JVIEW. Any ideas?
