Hi Saravana
You can use batch file to run your standalone java program.
The contents of the batch file would be as follows:
@echo off
if "%OS%" == "Windows_NT" setlocal
rem
rem Sets the CLASSPATH environment variable to include all JAR files
rem required for the JRC then compiles and jars Java file(s).
rem
rem Edit the environment variable BOBJ_JAVA_LIB to point to the
rem location where you have the JRC jar files.
rem
rem Make sure to define any other required libraries in the environment
rem variable CLASSPATH.
rem
rem Make sure you have defined the environment variable JAVA_HOME
rem
set BOBJ_JAVA_LIB=c:\Program Files\Business Objects\Common\3.5\java\lib
set CURRENT_DIR=%cd%
echo Using JAVA_HOME: %JAVA_HOME%
echo Using CURRENT_DIR: %CURRENT_DIR%
set RUNJAVA="%JAVAHOME%/bin/java"
set RUNJAVAC="%JAVAHOME%/bin/javac"
set RUNJAR="%JAVAHOME%/bin/jar"
set CLASSPATH=%BOBJ_JAVA_LIB%\ReportViewer.jar;%BOBJ_JAVA_LIB%\ReportPrinter.jar;%BOBJ_JAVA_LIB%\CrystalCommon.jar;%BOBJ_JAVA_LIB%\CrystalDatabaseConnectors.jar;%BOBJ_JAVA_LIB%\CrystalReportingCommon.jar;%BOBJ_JAVA_LIB%\CrystalFormulas.jar;%BOBJ_JAVA_LIB%\CrystalQueryEngine.jar;%BOBJ_JAVA_LIB%\CrystalReportEngine.jar;%BOBJ_JAVA_LIB%\keycodeDecoder.jar;%BOBJ_JAVA_LIB%\MetafileRenderer.jar;%BOBJ_JAVA_LIB%\rpoifs.jar;%BOBJ_JAVA_LIB%\jrcerom.jar;%BOBJ_JAVA_LIB%\jrcadapter.jar;%BOBJ_JAVA_LIB%\rascore.jar;%BOBJ_JAVA_LIB%\rasapp.jar;%BOBJ_JAVA_LIB%\Serialization.jar;%BOBJ_JAVA_LIB%\external\log4j.jar;%BOBJ_JAVA_LIB%\external\icu4j.jar;%BOBJ_JAVA_LIB%\external\Concurrent.jar;%BOBJ_JAVA_LIB%\external\xercesImpl.jar;%BOBJ_JAVA_LIB%\external\xml-apis.jar;%BOBJ_JAVA_LIB%\CrystalCharting.jar;%BOBJ_JAVA_LIB%\CrystalContentModels.jar;%BOBJ_JAVA_LIB%\CrystalExporters.jar;%BOBJ_JAVA_LIB%\CrystalExportingBase.jar;%CURRENT_DIR%;%CLASSPATH%
%_RUNJAVAC% -classpath "%CLASSPATH%" *.java
%_RUNJAVA% -classpath "%CLASSPATH%" HelloWorldSwing
// HelloWorldSwing is the name of your .java file
Make sure you have all the jar files in the lib directory.
Hope this helps you.
Thanks
