Scripts in frameworks direcotry needs to be revisted to set up CLASSPATH
properly
---------------------------------------------------------------------------------
Key: DERBY-1597
URL: http://issues.apache.org/jira/browse/DERBY-1597
Project: Derby
Issue Type: Bug
Components: Demos/Scripts
Affects Versions: 10.2.0.0
Reporter: Ramandeep Kaur
Assigned To: Andrew McIntyre
Need to revisit scripts in directory frameworks/embedded/bin and
frameworks/NetworkServer/bin for setting up CLASSPATH properly. The current
problem is as following:
If user already has a CLASSPATH set on their system, the CLASSPATH is not set
again within the script. Therefore, there are no derby classes in the CLASSPATH
which results in java command failing as it can not find the derby class it is
calling. Basically, to make the scripts work, user has to either issue command
"set CLASSPATH=" or have derby jar files be appended to their system CLASSPATH
before running any frameworks batch script.
In ksh scripts, there is same problem except that the user has to issue
command "export CLASSPATH=" or have derby jar files be appended to their system
CLASSPATH only once as whatever CLASSPATH is set up by scripts is not visible
once the script is done.
So I am proposing the following solution so that frameworks scripts work
properly without interfering with system classpath or without any setup from
user.
In batch scripts:-
----------------------
1. Before line "call
"%DERBY_INSTALL%"/frameworks/embedded/bin/setEmbeddedCP.bat", save the current
classpath as follows:
set SAVED_CLASSPATH=%CLASSPATH%
2. Replace the following lines:
@if !"%CLASSPATH%"==! call
"%DERBY_INSTALL%"/frameworks/embedded/bin/setEmbeddedCP.bat
@if "%CLASSPATH%" == "" call
"%DERBY_INSTALL%"/frameworks/embedded/bin/setEmbeddedCP.bat
with
call "%DERBY_INSTALL%"/frameworks/embedded/bin/setEmbeddedCP.bat
Note: I have given the above as example only. The name of script that is
getting called may be different.
3. At the end of script, reset the CLASSPATH to system CLASSPATH as follows:
set CLASSPATH=%SAVED_CLASSPATH%
In korn scripts:-
----------------------
In ksh script, even though system classpath is only modified within the script
and is not effective once script exits, to be consistent with batch scripts, do
the following:
1. Before line ". "$DERBY_HOME"/frameworks/embedded/bin/setEmbeddedCP.ksh"
save the current classpath as follows:
export SAVED_CLASSPATH=$CLASSPATH
2. Replace the following lines:
[ -z "$CLASSPATH" ] && {
. "$DERBY_HOME"/frameworks/embedded/bin/setEmbeddedCP.ksh
}
with
. "$DERBY_HOME"/frameworks/embedded/bin/setEmbeddedCP.ksh
Note: I have given the above as example only. The name of script that is
getting called may be different.
3. At the end of script, reset the CLASSPATH to system CLASSPATH as follows:
export CLASSPATH=$SAVED_CLASSPATH
