Nick, what compile problems are you having? I tested on Debian 3.1 (sarge) and everything worked fine for me. Using Apache Axis as a SOAP engine for OpenACS seems like overkill. As Claudio mentions, you may want to investigate TclSOAP first. -- Dossy

Hi Dossy,

I managed to compile nsjk2. However when I startup the openacs config.tcl file with the extras needed to configure nsjk2, I get the following error in the log file...

[14/Dec/2004:14:07:26][3272.16384][-main-] Notice: modload: loading '/usr/local/aolserver/bin/nsjk2.so'

The settings in my config file for nsjk2 are...

# nsjk2 configuration

ns_section ns/module/nsjk2
ns_param serverroot $env(TOMCAT_HOME)

ns_section ns/server/${server}/modules
ns_param nsjk2 ${bindir}/nsjk2.so

ns_section ns/server/${servername}/module/nsjk2/gzip
ns_param enabled on
ns_param level 4
ns_param minsize 0

ns_section ns/server/${server}/module/nsjk2/utils
ns_param nsjavatclbridge ${bindir}/nsjavatclbridge.so

# -------------------------------------------------------

Would you know why the jvmGLOBAL variable isn't being assigned a jvm instance?

Thanks,
Nick.

Is it possible that it just isn't seeing the JVM? Might be worth checking your paths and environment variabls for the user that aols runs as.

I set the JAVA_HOME variable as follows:

sudo /usr/bin/env -i JAVA_HOME=/usr/local/j2sdk1.4.2_04 TOMCAT_HOME=/usr/local/tomcat LD_LIBRARY_PATH=/usr/local/tomcat/lib:/usr/local/j2sdk1.4.2_04/jre/lib/i386:/usr/local/j2sdk1.4.2_04/jre/lib/i386/server /usr/local/aolserver/bin/nsd -ft /usr/local/aolserver/sample-config.tcl -u ncarroll -g web

I don't think the paths are the problem.
