compiling java files

[Jaki-2]

Hi,
I was going through Si Chen's tutorials and working on the hello3 app. As part of that, I am required to write a java program but it seems to compile it you have to use ant and build.xml (new to java, so these concepts are new to me as well). The tutorial says build.xml can usually be copied over from the other ofbiz apps but a cross examination of the different build.xml files revealed some differences to me. So, what changes do I have to make to make it work for my app or I can, as the tut says, just copy it into my app folder? Kindly help

Hi,

Copy the build.xml to your application.

Then put project name as your project name component, and also change
the <target name="init"> Property value to your project name.It will
build the jar file in that name.

 

<project name="demoPurpose Component" default="jar" basedir=".">

 

<target name="init">

        <property environment="env"/>

        <property name="desc" value="demoPurpose Component"/>

        <property name="name" value="demoPurpose"/>

        <property name="ofbiz.home.dir" value="../.."/>

        <property name="src.dir" value="src"/>

        <property name="dtd.dir" value="dtd"/>

        <property name="lib.dir" value="lib"/>

        <property name="build.dir" value="build"/>

    </target>

Hello Jaky,

You can put the example component's build.xml file in your own component.
build.xml files are very simple to understand.
It may possible that you will get the compilation error.
This kind of error can be solved by including the JAR files in your
"classpath" definition in build.xml file.

Suppose you are getting following kind of errors :

classes:
    [javac] Compiling 1 source file to
/home/ashish/ofbiz_dev/other/hot-deploy/practice/build/classes
    [javac]
/home/ashish/ofbiz_dev/other/hot-deploy/practice/src/org/ofbiz/practice/PracticeEvents.java:4:
package javax.servlet.http does not exist
    [javac] import javax.servlet.http.HttpServletRequest;
    [javac]                           ^
    [javac]
/home/ashish/ofbiz_dev/other/hot-deploy/practice/src/org/ofbiz/practice/PracticeEvents.java:5:
package javax.servlet.http does not exist
    [javac] import javax.servlet.http.HttpServletResponse;
    [javac]                           ^

This kind of error is nothing but the Java file is unable to to find the
package.
This kind of error can be solved by putting the "j2eespecs" folder in the
classpath target.

See the below contents :-

    <target name="classpath">
        <path id="local.class.path">
            <fileset dir="../../framework/base/lib" includes="*.jar"/>
            <fileset dir="../../framework/base/lib/commons"
includes="*.jar"/>
            <fileset dir="../../framework/base/lib/j2eespecs"
includes="*.jar"/>
            <fileset dir="../../framework/base/build/lib" includes="*.jar"/>

I hope this will help you to come on right track.

Acc. to the tutorial, I should navigate to my component folder (hot-deploy/hello3) and run 'ant'. But doing so gives me the error 'ant is not recognized as an internal or external command'. Do I need to copy ant.bat from main ofbiz folder over to this one??

[Das_Pramod]

Don't copy ant.bat from main ofbiz folder.Just set the ANT_HOME path in
the Environment Variables.

You need to have ant installed and have it on the path (I guess the installation does put ant in the path)
