Forum OpenACS Q&A: nsjava with Aolserver 4.08

Posted by Jeff Wang on 06/14/05 11:32 PM

Hi all,

Our research group has gotten nsjava working well with Aolserver 3.4 and OpenACS 4.6. However, we wanted to upgrade to Aolserver 4.08 and couldn't seem to get nsjava running there. The error log reports :

/home/aolserver408/bin/libnsjava.so: undefined symbol: NsTclDbCmd
[14/Jun/2005:12:27:45][16562.1024][-main-] Fatal: modload: failed to load module '/home/aolserver408/bin/libnsjava.so'

Does anyone know what this error is and how to fix it? Is nsjava even compatible with Aolserver 4.x??

Thanks for the help!
Jeff

Jeff, in addition to here, you definitely should ask about this on the AOLserver list.

Also, what are you using nsjava for? I'm curious...

Hi Andrew,

We're consuming webservices as a client and are using Java. We use nsjava to instantiate classes and invoke methods for utilizing the webservices in TCL/Openacs.

Hi, I tried to run configure and make, make install but have problems. I installed the java SDK for the javac compiler.

./configure --prefix=/usr/local/aolserver40r10-chroot --with-aolserver-src=/opt/source/installer/package_dir/aolserver-4.0.10 --with-jdk=/usr/lib/SunJava2-1.4.2

Was not able to find libjava.so ... libraries. Looking at the configure script I found out, that it is grepping for libjava.so using "find $JDK_DIR -name libjava.so" which returns nothing. I changed that to use the directory /usr/java/j2re1.4.2_04/lib/i386 where all the libraries are and configure worked. Same I did for all the other java libraries in configure:

Using c-compiler:      gcc
JDK Version:           1.2
Install libnsjava.so:  /usr/local/aolserver40r10-chroot/bin
Aolserver Version:     3_0_PLUS
Aolserver include:     /opt/source/installer/package_dir/aolserver-4.0.10/include

jdk include:           /usr/lib/SunJava2-1.4.2/include
jdk platform include:  /usr/lib/SunJava2-1.4.2/include/linux
libjava.so dir:        /usr/java/j2re1.4.2_04/lib/i386

libjvm.so dir:         /usr/java/j2re1.4.2_04/lib/i386/client

But calling make fails:

building "java"
make[1]: Entering directory `/opt/source/installer/package_dir/aolserver-4.0.10/nsjava-1.0.5/java'
/usr/lib/SunJava2-1.4.2/bin/javac -g -classpath /usr/lib/SunJava2-1.4.2/lib/tools.jar:/opt/source/installer/package_dir/aolserver-4.0.10/nsjava-1.0.5/java ../java/nsjava/internal/Interp.java

Any idea?

Has anyone solved this? I have just posted a similar question to the aolserver list.

Hi Mark,

We never ended up solving this issue. Instead, we had a workaround in which we run an instance of aolserver 3.x that handles all the nsjava stuff. All the aolserver 4.x instances will forward requests to the 3.x nsjava gateway.

Regards,
Jeff
