[Bug java/20394] New: Can't run db2 jdbc application compiled with gcj

[delarosa at ilstechnology dot com]

Hello,

I managed to get jdbc MSSQL & ORACLE test apps work just fine. I have not been
able to make DB2 work. Here is what I get. Does this mean something is missing
on the gcj classes ? I can provide sample source and the shared libs and/or the
jars ....

This means either ibm's .jar file contains classes which reference other classes which are not there and 
since gcj's runtime does not do lazy biind, we fail 
---or---
could mean gcj is going wrong.

Does this:

sun.io.ByteToCharConverter not
found in gnu.gcj.runtime.SystemClassLoader{urls=[file:./],


mean the the gcj runtime library has no sun.io.ByteToCharConverter ? If so, is
there a way to add it into libgcj.so or could I extract it from the sun package
and compile it along my othe files ?

Hmm, this seems wrong, no body should be refering to a sun. class really.

Thats a bug in upstream, the jdbc connector/application here. No application
should access sun classes. File a bug against them. Even SUN says: Don't use
them directly. We did the same successfully for a bunch of Apache projects in
the past.

Thanks for the response. What is upstream ? Is that a gcj component ? Where
exactly should I post the bug ? On the meantime, I plan to extract that
particular class and compile it in with the application. My guess is that DB/2
jars are using the sun.io.ByteToCharConverter which is not recommended right ?
Any help is greatly appreciated.

Upstream is the provider of your jdbc provider. DB/2 in your case.

Hello, sorry for being a pest. You indicated a company called upstream which
provides the jdbc driver for IBM. Can you please share their web url ? I tried
several searches but none made sense. Many thanks in advance.

upstreaming is not the name of a company but just a way to say the company which provided you with 
the jar file, I would expect it be IBM.  In which case I would contact the provider of the Jar file to figure 
out if there is anything they can do to fix this.

Ok. Thanks, that is what I thought originally. Yes, I will contact IBM but I
suspect it won't be speedy -- on the meantime I will extract the class from
rt.jar or wherever it is --  and proceed with the validation. Why wouldn't
libgcj.so contain this, I have seen the symbols in it and there is plenty of
sun.xx.xx ?

Hello, 
Tried to extract a bunch of classes fron Sun's rt.jar and I ended it when it
needed some internal class sun.io.CharacterEconding$2 ... So, does anybody have
some experience with a jdbc driver for DB2 that can be compiled with gcj and 
actually run ? Any pointers are greatly appreciated. We have Oracle, MSSQL
running just fine -- and very fast, but we need DB2. 
Thanks, David

Closing as this is not our bug.
