There are now two methods of compiling the server distribution. The existing |
| 8 |
> |
Makefile method is still supported, but is of course limited in the OS's on |
| 9 |
> |
which it can be run. The preffered method will be an XML based build script |
| 10 |
> |
using ANT (http://jakarta.apache.org/ant) which will run on any platform. |
| 11 |
> |
However, at this stage the ANT scripts are not completely finished and may |
| 12 |
> |
have some odd behaviour. |
| 13 |
|
|
| 14 |
< |
The following sequence of commands should suffice. They will probably need |
| 15 |
< |
to be run in seperate terminal windows. |
| 14 |
> |
We envisage both the Makefile and ANT setups being maintained for some time, |
| 15 |
> |
giving the developer a choice. This document still outlines the Makefile |
| 16 |
> |
method of compiling, and will do so until such a point as the ANT scripts |
| 17 |
> |
are deemed reliable. If, however, you wish to give the ant script a whirl, |
| 18 |
> |
try the following after setting up ANT (see the ANT website for details); |
| 19 |
|
|
| 20 |
< |
make runcore |
| 17 |
< |
make runclientinterface |
| 18 |
< |
make rundbinterface |
| 19 |
< |
make runfiltermanager |
| 20 |
< |
make runrootfilter |
| 21 |
< |
make runfilter NAME=filter1 |

If all is working this will ensure every component, including the IDL, is |
| 23 |
< |
compiled as required before execution. |

Compiling |
| 23 |
> |
--------- |
| 24 |
|
|
| 25 |
< |
nb. you will need to ensure your classpath is correctly set prior to |
| 26 |
< |
running, otherwise java will fail to find the jacorb classes and the |
| 27 |
< |
XML parsing packages. |
| 25 |
> |
The server can now easily be compiled without worrying about setting up any |
| 26 |
> |
of the CLASSPATH's, or setting the path to JacORB. It's all self contained. |
| 27 |
> |
|
| 28 |
> |
Typical sequence to compile; |
| 29 |
> |
|
| 30 |
> |
./configure |
| 31 |
> |
make build |
| 32 |
> |
make install prefix=/some/path |
| 33 |
> |
make clean |
| 34 |
> |
|
| 35 |
> |
In more detail, the first line ensures that the required libraries are |
| 36 |
> |
available, and sets the Makefiles up so they know where everything is. |
| 37 |
> |
The second line compiles all of the code and creates a JAR file in the |
| 38 |
> |
build directory. |
| 39 |
> |
The install line installs the server and libraries to a given location, |
| 40 |
> |
along with the configuration files. |
| 41 |
> |
Finally, the last line cleans up. |
| 42 |
> |
|
| 43 |
> |
Running |
| 44 |
> |
------- |
| 45 |
> |
|
| 46 |
> |
It is recommended that the components are started up in the following order. |
| 47 |
> |
|
| 48 |
> |
(This can be on multiple hosts if required, as long as the order is correct). |
| 49 |
> |
|
| 50 |
> |
Core |
| 51 |
> |
ClientInterfaceMain |
| 52 |
> |
DBInterface |
| 53 |
> |
FilterManager |
| 54 |
> |
RootFilter |
| 55 |
> |
FilterMain |
| 56 |
> |
Client |
| 57 |
> |
|
| 58 |
> |
It is not necessary to start both the ClientInterfaceMain and DBInterface, |
| 59 |
> |
the server will handle only one or both. Multiple Filter's can be started |
| 60 |
> |
as required. |
| 61 |
> |
|
| 62 |
> |
These are all loaded through the ComponentManager. More details on how to |
| 63 |
> |
operate this will be provided later on. Typing "make run" will make an |
| 64 |
> |
attempt to load it up. |
| 65 |
> |
|
| 66 |
> |
Check build/etc/default.properties to set the startup list and order. |
| 67 |
> |
|
| 68 |
> |
nb. You will need to ensure that the relevant libraries are in the |
| 69 |
> |
build/lib directory. See the README in there for details. |

Makefile |
| 72 |
> |
======== |
| 73 |
> |
The following targets are available; |
| 74 |
> |
|
| 75 |
> |
build |
| 76 |
> |
|
| 77 |
> |
Compile the entire server package, include the IDL file. Generates the |
| 78 |
> |
JAR file for the final package. |
| 79 |
> |
|
| 80 |
> |
run |
| 81 |
> |
|
| 82 |
> |
Run's the server from the JAR file in /build. |
| 83 |
> |
|
| 84 |
> |
clean |
| 85 |
> |
|
| 86 |
> |
Cleans all compiled code, and javadoc pages. |
| 87 |
> |
|
| 88 |
> |
distclean |
| 89 |
> |
|
| 90 |
> |
Also cleans files left by configure, including the libraries. |
| 91 |
> |
|
| 92 |
> |
install |
| 93 |
> |
|
| 94 |
> |
Installs the server to a given directory. Also takes a prefix; |
| 95 |
> |
make install prefix = /usr/i-scream |
| 96 |
> |
|
| 97 |
> |
cvsbuild |
| 98 |
> |
|
| 99 |
> |
Builds any tagged version of the server from CVS. This saves the need to |
| 100 |
> |
checkout a version to build it, as it's all done automatically; |
| 101 |
> |
make install rev = RELEASE_1 |
| 102 |
> |
Default tag is HEAD. |
| 103 |
> |
|
| 104 |
> |
javadoc |
| 105 |
> |
|
| 106 |
> |
Builds all the javadoc pages in the `doc' directory. |
| 107 |
> |
|
| 108 |
> |
buildutil |
| 109 |
> |
|
| 110 |
> |
(it is recommended you run a "make clean" first) |
| 111 |
> |
Builds a seperate JAR file, in `build' called `iscream-util.jar'. |
| 112 |
> |
This file contains just the uk.ac.ukc.iscream.util package for |
| 113 |
> |
use in other parts of the system, such as the clients. |
| 114 |
> |
|
| 115 |
> |
createtable |
| 116 |
> |
|
| 117 |
> |
Creates the ipacket table in the mySQL database. This is required for |
| 118 |
> |
the database side of the server. |
| 119 |
> |
|
| 120 |
> |
droptable |
| 121 |
> |
|
| 122 |
> |
Drops an ipacket table from the mySQL database if one exists. |
