Question

ANT: update JAR file

Asked by: ank9

I have jar file called "webtop.jar" at the following location

C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib/webtop.jar

In this jar there is a properties file

com\documentum\web\formext\session\AuthenticationSchemes.properties

I need to write a ANT target which would pick up a properties file from another location and update this properties file (within the jar)

So I did the following

<target name="updateJar" >
        <jar jarfile="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib/webtop.jar"
               includesfile="C:/cvs_repo/Documentum/webtop/build/AuthenticationSchemes-websso.properties"
                           basedir="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib"
                            update="true"  />
</target>

Although this is not giving any error but it does not update the properties file in the JAR.
Can someone please let me know howt o achieve this?

thank you

Make

>> includesfile="C:/cvs_repo/Documentum/webtop/build/AuthenticationSchemes-websso.properties"

the nested following (and adjust the jar task accordingly)

 <fileset file="C:/cvs_repo/Documentum/webtop/build/AuthenticationSchemes-websso.properties"/>

by: CEHJPosted on 2009-10-07 at 02:54:35ID: 25513562

Or perhaps better

<fileset dir="C:/cvs_repo/Documentum/webtop/build" includes="AuthenticationSchemes-websso.properties"/>

Thank you

I did this

      <target name="websso.is.false" unless="${websso}">
           <echo>websso == FALSE</echo>
              <jar jarfile="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib/webtop.jar"                            
                           basedir="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib"
                            update="true"  >
                <fileset file="C:/cvs_repo/Documentum/webtop/build/AuthenticationSchemes-websso.properties" />
            </jar>
      </target>

but it gives me the following error

A zip file cannot include itself

 

by: ank9Posted on 2009-10-07 at 02:56:10ID: 25513571

This also gives the same error

      <target name="websso.is.false" unless="${websso}">
           <echo>websso == FALSE</echo>
              <jar jarfile="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib/webtop.jar"                            
                           basedir="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib"
                            update="true"  >
                    <fileset dir="C:/cvs_repo/Documentum/webtop/build" includes="AuthenticationSchemes-websso.properties"/>
            </jar>
      </target>

Try changing this

>><jar jarfile="C:/cvs_repo/Documentum/webtop/src/WEB-INF/lib/webtop.jar"            

to

<jar jarfile="C:/Documents and Settings/USERNAME/Desktop/webtop.jar"            

and get the jar from your desktop (obviously with the correct username)

 

by: ank9Posted on 2009-10-07 at 04:12:10ID: 25514050

Thanks a lot.

It works. But there are a couple of problems

<target name="websso.is.false" unless="${websso}">
           <echo>websso == FALSE</echo>            
              <jar jarfile="C:/Documents and Settings/user/Desktop/webtop.jar"                            
                           basedir="C:/cvs_repo/Documentum/webtop/build"
                            update="true"  >
                    <fileset dir="C:/cvs_repo/Documentum/webtop/build" includes="AuthenticationSchemes-websso.properties"/>
            </jar>
      </target>


1. the base directory which contains the properties file to be added to the jar contains some other files as well. In the jar I want only "AuthenticationSchemes-websso.properties" to be added. but the above task is adding all the files from the source directory.

2. webtop.jar has the following structure.
   com/documentum/web/formext/session
The properties file needs to be added to the session folder. But right now is is getting added parallel to the com folder.

Can you please let me know how to solve the above two problems.

Thank you

Try the below instead

                    <fileset dir="C:/cvs_repo/Documentum/webtop/build" excludes="**/*" includes="AuthenticationSchemes-websso.properties"/>

<target name="websso.is.false" unless="${websso}">
           <echo>websso == FALSE</echo>            
              <jar jarfile="C:/Documents and Settings/user/Desktop/webtop.jar"                            
                           basedir="C:/cvs_repo/Documentum/webtop/build"

                    <fileset dir="C:/cvs_repo/Documentum/webtop/build" excludes="**/*"
                                           includes="AuthenticationSchemes-no-websso.properties"/>
            </jar>
      </target>
      

Still it's adding the other files.

Anyone on this please?

Give the following a try instead of jar

	<zip destfile="C:/Documents and Settings/user/Desktop/webtop.jar"                            
	    update="true">
	    <fileset dir="C:/cvs_repo/Documentum/webtop/build">
		<include name="AuthenticationSchemes-no-websso.properties"/>
	    </fileset>
