Compile and Run

The best way to avoid CLASSPATH issues is to use ant for both compiling and running your program. The SAADA_DB_HOME/bin/build.xml can be used as template.

Copy SAADA_DB_HOME/bin/saadadb.properties in your project directory (let’s say PROJECT_DIR)

Edit your build file : e.g. PROJECT_DIR/build.xml with something like that

<project name="MyProject" default="MyProgram.run">

        <property file="saadadb.properties"/>

        <property name="jvm_initial_size" value="-Xms64m" />

        <property name="jvm_max_size"   value="-Xmx1024m" />

        <!--

          This classpath is used by all java calls.

          Classes or jar files specifiv for an application must be added here

        -->

          <path id="saadadb.classpath">

                <pathelement location="${SAADA_DB_HOME}/algo_correlation/"/>

                <fileset dir="${SAADA_DB_HOME}/lib/axis-1_2_1/">

                      <include name="**/*.jar" />

                </fileset>

                <fileset dir="${SAADA_DB_HOME}/lib/">

                      <include name="**/*.jar" />

                </fileset>

                 <pathelement location="${SAADA_DB_HOME}/class_mapping/"/>

                <pathelement location="${J2EE_HOME}/lib/j2ee.jar" />

                <pathelement location="./" />

                 <fileset dir="${JAVA_HOME}/lib/">

                      <include name="**/*.jar" />

                </fileset>

                <fileset dir="${SAADA_DB_HOME}/jtools/ant/lib/">

                      <include name="**/*.jar" />

                </fileset>

            <!- 

               Added to include you classes

            -->

            <pathelement location="./"/>        

        </path>





        <!--

          Task compiling your project

        --> 

        <target name="MyProgram.compile">

                 <javac fork="true" executable="${SAADA_DB_JAVAC}" debug="on" 

                        srcdir="."  destdir=".">

                <classpath refid="saadadb.classpath"/>

            </javac>

        </target>

                         

      <!--

          Task running your project

        --> 

     <target name="MyProgram.run" depends="MyProgram.compile">

         <java jvm="${SAADA_DB_JAVA}" classname="MyClass" 

                   fork="true">

             <classpath refid="saadadb.classpath"/>

                <jvmarg value="${jvm_initial_size}" />

             <jvmarg value="${jvm_max_size}" />

             <arg value="${SAADA_DB_NAME}"/>

         </java> 

     </target>

Now you just have to type ant in PROJECT_DIR tu run your project. - Ant will execute the default task MyProgram.run which has a dependency with the compilation task MyProgram.compile.

In the above example, we suppose that the main class is MyClass and that MyClass.java is in PROJECT_DIR.
