problem in making jar and war based on the 'src' package hierarchy!

[yuvaraj KumarAmudhan]

hello all,

I have the package hierarchy like this,

src
- com.test.servlets -> contains all the servlet sources (*.java).
- com.test.beans -> contains all the bean sources (*.java).

with 'ant' build tool, i compiled all the files and store the class files in the 'build' folder. Then the build folder will be,

build
- com.test.servlets -> contains all the class files of servlets (*.class).
- com.test.beans -> contains all the class files of beans (*.class).

What i need to do,
I need to fetch the class files from the build folder and bundle the web contents(servlets, jsp, images) in the web archive (.war)
and
I need to bundle the beans(core business classes and interfaces) in generic archive (.jar).

[Note: In both archives, the package hierarchy should be the same (in the above) ]

How it can be done?


Thank You!

Yuvaraj,
What do you have so far? What problem are you running into?

[yuvaraj KumarAmudhan]

hello sir,

problem means, In what way i can write an Ant Task to build the war and jar from the 'build'(which has the compiled class files) folder. that is,


build
---------- servlet classes --------> to war
---------- bean classes --------> to jar.

I think it might be clear!

Thank You for your Reply

Jeanne was asking you to post the Ant tasks that you have so far to build your WAR and JAR (see NotACodeMill). And asking you to say why those tasks were not behaving as you expected.

[Jeanne Boyarsky]

Peter: Right.

Yuvaraj: Note that Jeanne is a female name.

hello sir/madam,

my directory structure is,
                        testbean(project)
                              - src
                                   - com.testbean.servlets
                                   - com.testbean.beans
                              - build
                                   - classes
                                   - deployers
                                           - application.xml
                                           - web.xml
                                           - ejb-jar.xml
                                   - ear
                                   - war
                                   - jar
                              - lib
                              - web
                                   - html
                                   - jsp
                                   - index.jsp

                              - build.xml

My code here is,

  <project name="BeanTest" default="all" basedir=".">
	<property name="dir.base" value="${basedir}" />
	
	<property name="ear" value="${basedir}/build/ear" />
	<property name="war" value="${basedir}/build/war" />
	<property name="jar" value="${basedir}/build/jar" />
	
	<property name="src" value="${basedir}/src" />
	<property name="classdir" value="${basedir}/build/classes" />
	<property name="deployers" value="${basedir}/build/deployers" />
	
	<property name="web" value="${basedir}/web" />
	
	<path id="classPath"> 
		<fileset dir="${dir.base}/lib" includes="**/*.jar"> </fileset>
	</path>

	<target name="init">
        <mkdir dir="${war}/WEB-INF" />
    	<mkdir dir="${war}/WEB-INF/classes" />
    	<mkdir dir="${ear}/META-INF" />
    </target>
	
	<target name="compile" depends="init">
		<javac classpathref="classPath" destdir="${classdir}" srcdir="${src}" >
		</javac>	
	</target> 
	
	<target name="buildWar" depends="compile">
		<copy todir="${war}/WEB-INF/classes">
			<fileset dir="${classdir}"> </fileset>	
		</copy>
		<copy todir="${war}/WEB-INF">
			<fileset dir="${deployers}" includes="web.xml"> </fileset>		
		</copy>
		<copy todir="${war}">
			<fileset dir="${web}" includes="**/*.*"> </fileset>
		</copy>
		<jar destfile="${ear}/testbean.war" basedir="${war}" > </jar>
	</target>
	
	<target name="buildEar">
		<copy todir="${ear}/META-INF">
			<fileset dir="${deployers}" includes="application.xml"> </fileset>
		</copy>
		<jar destfile="${basedir}/testbean.ear" basedir="${ear}" > </jar>
	</target>
	
	<target name="buildJar">
		// what to do here?
	</target>
	
	<target name="all" depends="buildWar, buildEar, buildJar" />  

here i need to bundle the bean classes only into the jar file!



sorry if i pasted a long code here!

[Peter Johnson]

What have you tried for line 50? Hint: make use of the "includes" and/or "excludes" properties to select only the "com.testbean.beans" classes.

And now for another hint:
By the way, you should also change line 31 to only copy the com.testbean.servlets classes to the WAR:

<fileset dir="${classdir}" includes="com/testbean/servlets/**/*.class" />

You might have to try different "includes" settings, the one I gave should work but I didn't try it out so I cannot guarantee it.

[yuvaraj KumarAmudhan]

hello peter,
Already I have tried the thing you have mentioned!

If we use, includes='com/testbean/servlets/**/*.class' -> It will fetch the class files from the given path (not the entire package hierarchy i think) and will store them in the war.

But, for example,

if i include the war file(we have created in the previous step) in my application, can i use like,

import com.testbean.servlets.TestServlet;

(this statement might show some error about the path(com.testbean.servlets) we have specified)


Thank You for your reply peter!

[Peter Johnson]

If we use, includes='com/testbean/servlets/**/*.class' -> It will fetch the class files from the given path (not the entire package hierarchy i think) and will store them in the war.

I disagree.

My simple build.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<project name="temp" default="build">
  <target name="build">
    <jar destfile="target/dist/One.jar">
      <fileset dir="target/classes" includes="org/peter/one/**/*.class"/>
    </jar>
    <jar destfile="target/dist/Two.jar">
      <fileset dir="target/classes" includes="org/peter/two/**/*.class"/>
    </jar>
  </target>
</project>

My file structure:

>dir target\classes /S /B
D:\opt\workspace\temp\target\classes\org
D:\opt\workspace\temp\target\classes\org\peter
D:\opt\workspace\temp\target\classes\org\peter\one
D:\opt\workspace\temp\target\classes\org\peter\two
D:\opt\workspace\temp\target\classes\org\peter\one\One.class
D:\opt\workspace\temp\target\classes\org\peter\two\Two.class

The ant run:

>ant
Buildfile: D:\opt\workspace\temp\build.xml

build:
      [jar] Building jar: D:\opt\workspace\temp\target\dist\One.jar
      [jar] Building jar: D:\opt\workspace\temp\target\dist\Two.jar

BUILD SUCCESSFUL
Total time: 0 seconds

The contents of the two JAR files:

>jar -xvf target\dist\One.jar
  created: META-INF/
 inflated: META-INF/MANIFEST.MF
  created: org/
  created: org/peter/
  created: org/peter/one/
 inflated: org/peter/one/One.class

>jar -xvf target\dist\Two.jar
  created: META-INF/
 inflated: META-INF/MANIFEST.MF
  created: org/
  created: org/peter/
  created: org/peter/two/
 inflated: org/peter/two/Two.class

I assume that this is what you wanted to do.

[yuvaraj KumarAmudhan]

Yes! This one! I'll try this.


Thank You Peter and All!
