1: webmail class compile
Posted by Claudio Cerasoli on 02/03/01 02:44 PM
Please, I use a blackdown Java 2 SDK Standard edition Version 1.3.0. I compile with success nsjava and in the server.log there is:

..... [03/Feb/2001:13:23:45][1457.1024][-main-] Notice: modload: loading '/usr/local/aolserver/bin/libnsjava.so' [03/Feb/2001:13:23:47][1457.1024][-main-] Notice: ModuleInit: Java Module ENABLED [03/Feb/2001:13:23:49][1457.1024][-main-] Notice: ModuleInit: JVM init succeeded!

so, i try to compile /web/server1/www/webmail/java/Makefile the result is:

Posted by Dan Wickstrom on 02/03/01 03:40 PM
Your need to set your CLASSPATH before you compile: 

1037 nsadmin@localhost:~/mirror/acs3-pg/www/webmail/java >export CLASSPATH=/home/nsadmin/bin/mail.jar:/home/nsadmin/bin/activation.jar:/home/nsadmin/mirror/acs3-pg/www/webmail/java:/home/nsadmin/bin/nsjava.jar
 
1038 nsadmin@localhost:~/mirror/acs3-pg/www/webmail/java >make

javac -g acspg/BLOB.java 

javac -g acspg/CLOB.java 

javac -g acspg/BlobDataSource.java 

javac -g acspg/ClobDataSource.java 

javac -g acspg/AttachmentsIter.java 

javac -g acspg/HeadersIter.java 

javac -g MessageComposer.java javac -g MessageParser.java Note: MessageParser.java uses a deprecated API.  Recompile with "-deprecation" for details. 1 warning

Make sure that your have the mail.jar and activation.jar files in your classpath. Read the webmail.html file in the doc directory for more details about these jar files. You must also have the nsjava jar file and the www/webmail/java directory in your classpath to successfully compile.

Posted by Dan Wickstrom on 02/04/01 04:06 PM
It sounds like you also need to set the classpath in your nsd.tcl file. Something like the following: 

ns_section "ns/server/${server}/module/nsjava"
        ns_param   EnableJava          "on"  ;# Set to on to enable nsjava.
        ns_param   VerboseJvm          "off"  ;# Same as command line -debug.
        ns_param   LogLevel            "Notice"
        ns_param   DestroyJvm          "off"  ;# Destroy jvm on shutdown.
        ns_param   DisableJITCompiler  "off"  
        ns_param   ClassPath "/usr/local/jdk/jdk118_v1/lib/classes.zip:/home/nsadmin/bin/nsjava.jar:/home/nsadmin/bin/activation.jar:/home/nsadmin/bin/mail.jar:/home/nsadmin/mirror/acs3-pg/www/webmail/java"

the sdk 1.3.0 dont have a classes.zip but the tools.jar and the rt.jar for the jre.
this is my nsd.tcl:

8: Response to webmail class compile (response to 1)
Posted by Bob Fuller on 02/05/01 08:28 AM
Thanks to you guys, I got quite a bit further in trying to figure out how to make webmail work!!!

My environment is as follows:

  • Open ACS 3.2.4
  • SuSE 7.0 linux (2.2.16)
  • postgresql-7.0.3
  • aolserver 3.2
  • JRE 1.3
    • I'm able to get to the point where the log says: 
    [04/Feb/2001:23:06:07][26072.1024][-main-] Notice: ModuleInit: Java Module ENABLED
    but then it just hangs.

    If I set VerboseJvm to "on", then the last 10 log entries I get are as follows: 

    [Preparing java/util/Collections$EmptyMap]
[Loaded java.util.Collections$ReverseComparator from /usr/lib/jre1.3/jre/lib/rt.
jar]
[Loading superclasses of java/util/Collections$ReverseComparator]
[Preparing java/util/Collections$ReverseComparator]
[Loaded java.lang.InheritableThreadLocal from /usr/lib/jre1.3/jre/lib/rt.jar]
[Loading superclasses of java/lang/InheritableThreadLocal]
[Loaded java.lang.ThreadLocal from /usr/lib/jre1.3/jre/lib/rt.jar]
[Loading superclasses of java/lang/ThreadLocal]
[Preparing java/lang/ThreadLocal]
    so it appears to hang at java/lang/ThreadLocal.

    I compiled using the instructions for CLASSPATH and LD_LIBRARY_PATH in the various postings I've seen to date. I found that I had to add /usr/lib/jre1.3/jre/bin and /usr/lib/jre1.3/jre/bin/classic (the latter is for libjvm.so) to LD_LIBRARY_PATH in my nsd startup environment, and that seems to have taken care of the missing libraries problem.

    Also, here's the relevant entries from my nsd.tcl file: 

    ns_section "ns/server/${server}/modules"
        ns_param   nsjava          ${bindir}/libnsjava.so

ns_section "ns/server/${server}/module/nsjava"
        ns_param   EnableJava          "on" 
        ns_param   VerboseJvm          "off"
        ns_param   LogLevel            "Notice"
        ns_param   DestroyJvm          "off"
        ns_param   DisableJITCompiler  "off"
        ns_param   ClassPath "/usr/lib/jre1.3/jre/lib/rt.jar:/usr/lib/jre1.3/jre/lib/tools.jar:/web/ruchirasala/www/webmail/java:/usr/local/aolserver/bin/nsjava.jar:/usr/local/aolserver/bin/mail.jar:/usr/local/aolserver/bin/activation.jar"
    Any ideas what could be causing this to hang? (Need any more info?)

Exception in thread "Thread-0" java.lang.UnsatisfiedLinkError: no nsjava in java.library.path

        at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1312)

        at java.lang.Runtime.loadLibrary0(Runtime.java:749)

        at java.lang.System.loadLibrary(System.java:820)

        at nsjava.NsLog.(NsLog.java:55)

        at MessageParser.process_queue(MessageParser.java:506)
I think the error is in ..nsjava/NsLog.java:
	System.LoadLibrary("nsjava")
What do you think?

In the blackdown site:
http://java.sun.com/j2se/1.3/docs/api/java/lang/ClassLoader.html#findLibrary(java.lang.String)
protected String findLibrary(String libname)


    Returns the absolute path name of a native library. The VM invokes this method to locate the native libraries

    that belong to classes loaded with this class loader. 

If this method returns null, the VM searches the library

    along the path specified as the java.library.path property.

    Parameters:

        libname - the library name

    Returns:

        the absolute path of the native library

    Since: 

        1.2 

    See Also: 

        System.loadLibrary(java.lang.String),

        System.mapLibraryName(java.lang.String)

Claudio,

The System.LoadLibrary command is correct.  It's trying to find a library called libnsjava.so, and it's not succeding.  How are your starting aolserver?  You need to make sure that the LD_LIBRARY_PATH environment variable is set so that libnsjava.so is included in the library path prior to starting aolserver.  Try starting the server in the foreground:

    cd /usr/local/aolserver

    export LD_LIBRARY_PATH=/usr/local/aolserver/bin:$LD_LIBRARY_PATH

    bin/nsd -fkt nsd.tcl

Bob,

What it the vendor for your jdk?

As far as I can tell your configuration looks correct, but I have to warn you that I have never tested with 1.3 jdk's.  On linux I've tested with 1.1 and 1.2 jdk's, and of all the jdk's that I tested with only the 1.1.8 jdk from Blackdown gave acceptable results on linux.  See the test summary at http://nsjava.sourceforge.net for more details.  This warning also applies to Claudio, but he appears to be really close to getting it working.

Bob,

I just realized that you're using a jre instead of a jdk.  That won't work, as any jni application such as nsjava requires a jdk.
