1: problem with nsjava version 1.0.4
Posted by Ola Hansson on 09/10/02 09:12 PM
Dan, since you've been hanging out here lately, I'll just post this here.

(Sorry I couldn't resist imitating your post😉)

I ran into an error message when I tried to configure nsjava, but I can't seem find the problem.

This is what I got: 

apt-get install jdk1.1-native-dev
tar -xvzf nsjava-1.0.4.tar.gz
cd nsjava-1.0.4
export PATH=$PATH:/usr/lib/jdk1.1/bin

./configure --prefix=/usr/local/aolserver 
--with-aolserver-src=/usr/local/src/aolserver/aolserver

debian:/usr/local/src/nsjava-1.0.4# ./configure 
--prefix=/usr/local/aolserver 
--with-aolserver-src=/usr/local/src/aolserver/aolserver

Looks like you are using a 1.2 JVM.

It appears that the configure script generated an error trying to process one of the temporary conftest files.  Try running "autoconf" in the /usr/local/src/nsjava-1.0.4 directory, and then try re-running configure again.  What release of debian are you using?

I'm running "unstable" on kernel 2.4.18. The jdk is Blackdown I think.

Try running it with the jdk explicitly specified: --with-jdk=/usr/lib/jdk1.1

Okay, good.  It looks like I need to cleanup the configure script so it doesn't default to using environment variables.  Just out of curiosity, do you have a JAVA_HOME environment variable set?

Nope, I don't. If I may bother you again, can you tell me if I can run Java servlets from nsjava/AOLserver or not? Also do you know/recomment any opensource Java Webmail solutions that are IMAP capable that I might try?

Thanks.

Technically, the answer is no, but I have loaded a JigSaw server into nsjava and used it to try out webdav support from aolserver (jigsaw should also provide servlet support), and I think someone mentioned that they had run tomcat from nsjava.

In essence, nsjava is a tcl extension module that allows you to load java libraries and access them from tcl.  nsjava isn't currently integrated with aolserver's http connection interface, so it's not possible to provide direct servlet support from nsjava.  At some point, I will probably try adding servlet support, since so many java packages are designed for use with servlets.  Adding servlet support will make re-use of java packages much easier.
