1: nsjava error
Posted by Andrew Smith on 03/20/02 01:55 PM
Hi, 

   I am trying to make use of webmail package of openacs 3.2.4.
I am using Redhat Linux 7.1 with Postgres Sql 7.1.3 and AOL3.2

   I have followed most the instructions on webmail installation that
I could find.

   I have downloaded and installed nsjava from sourceforge. 

The bin dir of my aolserver now contains 

libnsjava.so,nsjava.jar,activation.jar,mail.jar,mailapi.jar,imap.jar

The classpath in the server.tcl file contains

 ns_param   ClassPath
"/usr/local/jdk/jdk118_v3/lib/classes.zip:/usr/local/aol32/bin/nsjava.jar:/usr/local/aol32/bin/activation.jar:/usr/local/aol32/bin/mail.jar:/web/server/www/webmail/java"

And The modules 

ns_section "ns/server/${server}/modules"
        ns_param   nssock          ${bindir}/nssock.so
        ns_param   nslog           ${bindir}/nslog.so
        ns_param   nsperm          ${bindir}/nsperm.so 
#       ns_param   nscgi           ${bindir}/nscgi.so 
        ns_param   nsjava          ${bindir}/libnsjava.so


I have compiled the java files under /web/server/www/webmail/java
directory with no errors.

But still when I try to send a mail on page message-send-3.tcl . I get
the error 

"
Database Error
An error occured while we attempted to compose your message: 

                invalid command name "nsjava"

webmaster@yourdomain.com
"
Any help would be greatly appreciated
Thanks in advance

On message-send-3.tcl page I used 

ns_java MessageComposer::compose_message $outgoing_msg_id $tmpfile

but still it gave me same error

I then tried using 

exec java MessageComposer::compose_message $outgoing_msg_id $tmpfile

It gave me different error

"
Database Error

An error occured while we attempted to compose your message: 

       Can't find class MessageComposer::compose_message
        
webmaster@yourdomain.com

"

I then modified it to 


exec java MessageComposer $outgoing_msg_id $tmpfile


Then it gave me different error

"

do you have the EnableJava param under the right module? e.g. 
ns_section "ns/server/${server}/module/nsjava"
        ns_param    EnableJava      on

Hi 

 You were right. I modules section had acspg as the server directory.
I corrected it and java was successfully loaded 

 But when I tried to send mail it gave me this error


[21/Mar/2002:10:45:47][13011.7176][-conn0-] Error: JavaEvalCmd: error in command format

The ns_java command was

ns_java MessageComposer $outgoing_msg_id $tmpfile

Sorry the command was wrong I then corrected it to 

 ns_java MessageComposer::compose_message $outgoing_msg_id $tmpfile

I then added path of libnsjava.so to LD_LIBRARY_PATH because java was giving me an error that the file could not be found.

Then when I tried to send message I got this error

java.lang.NoClassDefFoundError: nsjava/NsLog

you have nsjava.jar in your classpath, but is it where it's being looked for?  you have to move it in by hand.

I restarted the aolserver and then tried again . This time it sent mail with out error.

But it did not come to my inbox. I searched for that mail and found it under 

/var/qmail/queue/mess/5/100699

I have done the part of alias and queue as mentioned in the webmail doc 

The content of my /var/qmail/users/assign file is 

+webmail-:postgres:505:505:/usr/local/aol32/qmail/alias:-::
.

=============

rcpthosts is

server.com

==============

virtualdomains is 

webmail.server.com:webmail-wm


===============

server.ini file under parameters

 ns_param AliasDirectory "/usr/local/aol32/qmail/alias"
 ns_param QueueDirectory "/usr/local/aol32/server/server/queue/"
