j2sdk1.4.0_01 and Tomcat 4.1.18. Re: [cobalt-developers] RAQ 4 - Is Java possible?

["Oleg Lioubtchenko" <OlegL@xxxxxxxxxxxx>]

Hi, John,



Yes, I am using j2sdk on my Cobalt Qube3. (Not on Raq).

Some months ago I used to work with JDK 1.3.3+Tomcat 3.x,

shipped in "pkg" format.

You can find this old Java on the  pkgmaster.com.

This combination works and not too bad.

But then I downloaded and installed new  J2SDK-

j2sdk1.4.0_01.

Also I installed jBoss 3.0.4+Tomcat 4.1.12 and the replaced Tomcat 4.1.12
with

Tomcat 4.1.18.

All these work OK.



As I understand there is no really big difference of our Cobalts (and may be
all kind of Raqs) from usual Linux-based PC.

All of them use Red-Hat oriented versions of Linux and you can use and
install the same versions of Java, as you can use for standard PCs.



About "no libraries" errors:

In my personal experience - if you see such kind of errors it does not mean
that you really need any of the libraries.

It means "things go wrong way".

It is usual situation on the all kind of Linux.

Sometimes (in very rear cases) you can find in the Net and install the libs
and all will be OK.

But usually it is not the way.

I remember that when I installed new version of mySql, I saw such an errors.

There is no connection with Java at all...



If you have old soft (old version of Java or old version of mySql, for
example) you should first de-install the old soft and only after that
install new version.

That is the common rule.

You may try to solve the problems with the libs and, may be you will be the
expert in this field, but the fast way is to remove old version and install
new one.

It is something like to try to solve "blue screen of death" problem under
NT/Win2000. Theoretically yes, you can find the error numbers and repair
register, etc.

But in reality you should re-format the HD and do all the things anew (just
try to copy data from HD and that's all).
