Ninf-G4 Invoke Server GT4java

This is the "invoke server" for GT4 WS GRAM written in java.
Although the "invoke server" GT4py is included in Ninf-G4, it does not
work on Windows.  "Invoke server" GT4java enables Ninf-G client running
on Windows to call WS GRAM.

Currently, many features such as "jobmanager", "backend", "count",
"redirect_outerr, "staging", and some other attributes of the client
configuration file are not supported by the "invoke server" GT4java.

1. Prerequisite
   - Java(JRE): 1.4 or later
   - CoG      : 4.1.2 or later
   - Ant      : 1.5 or later

2. Set environment variables.

   Before building "invoke server", set the following environment variables.

     {sh}
     $ COG_INSTALL_PATH=/path/to/cog
     $ GLOBUS_LOCATION=/path/to/GT4
     $ NG_DIR=/path/to/ninfg
     $ export COG_INSTALL_PATH GLOBUS_LOCATION NG_DIR
     $ source $GLOBUS_LOCATION/etc/globus-devel-env.sh
     {csh}
     % setenv COG_INSTALL_PATH /path/to/cog
     % setenv GLOBUS_LOCATION /path/to/GT4
     % setenv NG_DIR /path/to/ninfg
     % source $GLOBUS_LOCATION/etc/globus-devel-env.csh
     {Windows}
     You have to set environment variables by Control Panel.

   $COG_INSTALL_PATH specifies the location of the Java CoG Kit.
   It is used when the "invoke server" of GT4java is built.

   $NG_DIR specifies the localhost of Ninf-G.
   The "invoke server" of GT4java will be installed in $NG_DIR/bin.

3. Run a following command in ng-4.x.x/utility/invoke_server/gt4java directory.

     % ant

   This will compile the sources and build the "invoke server" for GT4java.

4. Edit file.

   Edit the following lines of file ng_invoke_server.GT4java or
   ng_invoke_server.GT4java.bat.

     JAVA_HOME=/path/to/java_home
     COG_INSTALL_PATH=/path/to/cog
     NG_DIR=/path/to/ninfg

5. Copy files.

   Copy the following files to $NG_DIR/bin

   {Linux, UNIX}
     - ng_invoke_server.GT4java

   {Windows}
     - ng_invoke_server.GT4java.bat
     - nglcp.bat

Now you are able to use ng_invoke_server.GT4java by specifying
<SERVER> "invoke_server" to "GT4java".
