Javadoc with Ant

I need to generate javadoc with Ant, however I'm just learning to use both. I am compiling with a root build.xml that antcalls to other build.xmls in child directories and so on until the lowest level is tasked to compile the source in its directory. Is there a way to handle this for javadoc? If I use the same methodology for javadoc, javadoc ends up generating the api docs multiple times bit by bit, but the result is that the output is just overwritten as many times as it's generated.
Is there a better way to do this? I can't seem to get all the api into one document.

Hi there,
I'm not totally sure your requirements here, but it sound like each separate build.xml generates a javadoc task. I would be inclined to remove these tasks from each of those builds, and only have one target from the main build.xml.
I have posted some information in a previous thread about how I use Ant to generate JavaDoc.
http://forum.java.sun.com/thread.jspa?threadID=534186&messageID=2588599#2588599
Now, in the root buid.xml file, either call the ant task seperately using the commandline:
ant.bat -f build.xml BuildJavaDocor, call the ant task internally at the end of the original task using:
<antcall target="BuildJavaDoc" />I hope this helps a bit? If not, please re-post here and we'll help your further.
Regards

  • Javadoc and ant problem

    Hi All,
    I have a problem running javadoc with ant. When I run javadoc from the command line it generates all documentation. From an ant task it gives me the following error:

    Hi,
    I would suggest there is a problem with the parameter in your XML file. So it would be best you could post the JavaDoc task here so everybody can analyze it for a possible error.
    So long.

  • JSP problem with ANT

    Hello!
    I built up a web site and I want to test them using ANT. It works fine with other web page, however it doesn't work with web pages with "session" statement. For example in login.jsp I have the following statement
    session.setAttribute("user", request.getParameter("userName"));
    And if the user's name and password are correct, the user is directed to home.jsp, where i have the following statement to retrieve the user's name:
    String id=session.getAttribute("user").toString();
    In order to test the above 2 pages with ANT, I have the following code in builder.xml:
    <?xml version='1.0'?>
    <project name="proj" default="test" basedir=".">
    <target name="test">
    <get src="http://path/login.jsp?userName=id&passWord=1111" dest="1.html" />
    </target>
    </project>
    When I run the script, I get the error that the home.jsp cannot be opened (see below)
    [get] Error opening connection java.io.IOException: Server returned HTTP response code: 500 for URL: http://path/home.jsp
    I am pretty sure the above error is caused by the "session" statement, because if I remove the statement in home.jsp, the page can be correctly opened. But I really need the "session" statement, Can someone tell me how to deal with it?
    thanks a million.

    Usually with a 500 error there's more detail in a server log somewhere. Can you find anything in stderr.log or some such?

    One mistake i find in your code is while retreiving the session value its session.getAttribute("userName"), as you stored the value using the parameter 'userName'. Is it not causing problem. Please check...

  • Generate HTML report with ANT

    Hello,
    I'm  new to FlexPMD. I have just generated my firsts reports. I try to generate HTML reports.
    I browse the documentation, this forum and the web and I find informations to :
    - generate documentation with Hudson
    - generate documentation with Maven
    - generate documentation with XSLT pmd.xml -> html
    Ok, I try to keep it simple. So I don't want to use Hudson.
    I'm using ANT, and I currently don't want to install/learn Maven.
    I'm using FlexUnit with ANT. And It's really simple to generate reports :
    <junitreport todir="${report.flexunit.loc}">
                <fileset dir="${report.flexunit.loc}">
                    <include name="TEST-*.xml" />
                </fileset>
                <report format="frames" todir="${report.flexunit.loc}/html" />
    </junitreport>
    I'm really new to FlexPMD, so I don't have currently a big knowledge, but it seems impossible to generate a HTML report just like junitreport. (1 line in an ANT task)
    I test the XSLT transformation found on this forum (thread "XSLT pmd.xml -> html"). It's really cool. But it's seems difficult, for example, to extract the wrong code part and add it to the HTML page.
    So, what is the simpler solution to generate HTML report just with FlexPMD/ANT ?
    Thanks !

    Hello,
    Currently you generate a PMD report with ANT  like this :
    <! -- define taskdef  -->
    < taskdef name="pmd"  classname="com.adobe.ac.pmd.ant.FlexPmdAntTask"  classpath="${build.pmd.loc}/flex-pmd-ant-task-${flexpmd.version}.jar">
             < classpath>
                 < path refid="flexpmd.base" />
                 < pathelement  location="${build.pmd.loc}/commons-lang-2.4.jar" />
                 < pathelement  location="${build.pmd.loc}/flex-pmd-core-${flexpmd.version}.jar" />
                 < pathelement  location="${build.pmd.loc}/flex-pmd-ruleset-api-${flexpmd.version}.jar"  />
                 < pathelement  location="${build.pmd.loc}/flex-pmd-ruleset-${flexpmd.version}.jar"  />
                 < pathelement  location="${build.pmd.loc}/plexus-utils-1.0.2.jar" />
             < /classpath>
    < /taskdef>
    then generate XML  report like this :
    < pmd  sourceDirectory="${src.loc}" outputDirectory="${report.loc}"  ruleSet="${build.pmd.loc}/rules.xml"/>
    The  XML contains some file nodes :
    < file  name="/Users/user/workspace/AS3_UTILS/src/utils/align/gridAlignSpaceNumber.as">
           < violation beginline="22" endline="22" begincolumn="0"  endcolumn="27" rule="adobe.ac.pmd.rules.naming.TooShortVariable"  ruleset="All Flex Rules" package="utils.align"  class="gridAlignSpaceNumber.as" externalInfoUrl="" priority="5">This  variable name is too short (3 characters minimum, but 1 actually).  Detects when a field, local, or parameter has a very short name<  /violation>
    < /file>
    The  message is in the text node  < violation>TEXT< /violation>
    For  me, we miss an important part of the message : the portion of the "bad"  code.
    It could be very usefull if PMD can generate  something like this :
    < file  name="">
           < violation beginline="" endline="" begincolumn=""  endcolumn="" rule=""  ruleset="" package=""  class="gridAlignSpaceNumber.as" externalInfoUrl="" priority="">
            < description>TEXT< /description>
            < code><CDATA[MY CODE
    MY CODE
    MY CODE]>< /code>
        <  /violation>
    < /file>
    With this, we can  generate "full" HTML report with XSLT transform easily.
    I  understand that it modify the standard XML schema of the output.
    So,  perharps it could be an option like this :
    < pmd fullDescription="true"  sourceDirectory="${src.loc}"  outputDirectory="${report.loc}"  ruleSet="${build.pmd.loc}/rules.xml"/>
    What do you think ?
    Thanks !

    I assume you have OC4J 10.1.3 webservices installed. Then you should not be using service-config.xml. Check out the 10.1.3 documentation about WebServiceAssembler. I am afraid, you are using 10.1.2 style service-config.xml along with 10.1.3 style WebServiceAssembler.

  • How to define new classpath of libraries while making jar files with ant

    I am useing eclipse and ant and trying to make a jar file. I have used some external jar files. I have managed to add external jar files to my jar. But Still I have a problem. In my project all libraries in lib folder. But when I put them into jar file. They are in the root folder.Classpath has changed and It couldn't find the class path.
    Is there any body knows how to define a new class path for external libraries with ANT. or How can I put my libraries into a lib folder in jar ?? I think both of them would solve my problem.
    thanks in advance.

  • Change manifest file in existing EAR file with ANT task

    Hi,
    I use ant task (ojdeploy) to create EAR files from ADF application.
    Now I want to add the application version number to MANIFEST.MF.
    Is it possible to do the manifest file modification IN THE EXISTING EAR FILE (or while creating the EAR file with ojdeploy) with ant task or do I have to do the modification in the source MANIFEST.MF and after this create EAR file with ojdeploy?
    BTW: I tried the <ear> task to create the EAR file instead of using ojdeploy but I was not able to find the needed deployment descriptor (appxml="application.xml") in my ADF appication.
    regards
    Peter

    Hi Peter,
    I don't know of a way to do it directly in ANT/ojdeploy. However, you could try exploding the EAR, updating the manifest, and recreating the EAR - cumbersome and slow, but it should work.

    I’m using windows 2000. I’ve tried with weblogic.jar from Weblogic Server 8.1
    SP1 and SP2. I’ve tried with JDK 1.4.1_02 and 1.4.2_04. If I’m using Ant 1.5.3
    then everything works perfectly.
    I’ve tried to remove the WLS included Ant version to avoid conflicts with Ant
    1.6.1 and Ant 1.5.3 (that comes with Weblogic server). I’ve tried to uninstall
    Weblogic Server and just keep weblogic.jar, but I still get the same error. I’ve
    tried to put weblogic.jar on the classpath, still not working. I’ve tried to remove
    all jar files from $ANT_HOME/lib except those jar files needed to run my test
    project - ant.jar and ant-launcher.jar, but still doesn’t work. If I change $ANT_HOME
    to Ant 1.5.3 and run Ant 1.5.3 then everything works. So it seems to have something
    to do with Ant 1.6.1.
    Here’s my example code:

    It doesn’t work with Ant 1.6.1 and weblogic.jar from WLS 8.1 SP1 and SP2. But
    it works perfectly if I change to Ant 1.5.3.

    Yes, this one is fixed in 8.1 SP3. If you need a patch before then,
    contact [email protected] and reference CR136493.

    I?m using windows 2000. I?ve tried with weblogic.jar from Weblogic Server 8.1
    SP1 and SP2. I?ve tried with JDK 1.4.1_02 and 1.4.2_04. If I?m using Ant 1.5.3
    then everything works perfectly.
    I?ve tried to remove the WLS included Ant version to avoid conflicts with Ant
    1.6.1 and Ant 1.5.3 (that comes with Weblogic server). I?ve tried to uninstall
    Weblogic Server and just keep weblogic.jar, but I still get the same error. I?ve
    tried to put weblogic.jar on the classpath, still not working. I?ve tried to remove
    all jar files from $ANT_HOME/lib except those jar files needed to run my test
    project - ant.jar and ant-launcher.jar, but still doesn?t work. If I change $ANT_HOME
    to Ant 1.5.3 and run Ant 1.5.3 then everything works. So it seems to have something
    to do with Ant 1.6.1.
    Here?s my example code:
    <project name="wlcompile_test" default="test" basedir=".">
         <target name="test" depends="init">
    <wlcompile srcdir="${src.dir}" destdir="${build.dir}">
    <javac debug="${build.debuginfo}" debuglevel="${build.debuglevel}"
    nowarn="${build.nowarn}" deprecation="${build.deprecated}" source="${build.source.version}"/>
    </wlcompile>
         </target>
    <target name="clean" depends="init">
    <delete dir="${build.dir}"/>
    </target>
    <target name="init">
    <taskdef name="wlcompile" classname="weblogic.ant.taskdefs.build.WLCompileTask"
    classpath="C:\P2Development\weblogic.jar"/>
    <property name="src.dir" value="src"/>
    <property name="build.dir" value="classes"/>
    <property name="build.compiler" value="modern"/>

    And I try to run ?ant test?
    It doesn?t work with Ant 1.6.1 and weblogic.jar from WLS 8.1 SP1 and SP2. But

  • Problem building with ant

    Hi all,
    For some reason i get the following error message when trying to build any of the code in the j2ee tutorial.
    C:\WINDOWS\system32\ntvdm.exe
    Error while setting up environment for the application. Choose 'close' to terminate the application
    If anyone has any ideas as to why this happens, any help would be much appreciated.
    thanks

    i'm using windows xp pro. i have actually sorted that problem out by replacing ant 1.3 with ant 1.5
    I now have another error message. When i try to run the application client with the foolowing command:
    C:\forte4j\j2sdkee1.3\bin>runclient client \examples\ears\SavingsAccountApp.ear -name SavingsAccountClient -textauth
    I get the following
    Initiating login ...
    Username = null
    Enter Username:guest
    Enter Password:guest123
    Binding name:`java:comp/env/ejb/SimpleSavingsAccount`
    Application threw an exception:java.lang.NoClassDefFoundError: SavingsAccountHome
    Unbinding name:`java:comp/env/ejb/SimpleSavingsAccount`
    Not sure why i am getting the exception.

  • How to start Bea 9 asynchronously with Ant?

    Unfortunately the whole text is condensed because of a forum bug. I hope, you still read it.
    With Bea 8 it was possible to start the Bea application server asynchronously with Ant.
    But I couldn't start <b>Bea 9</b> asynchronously with Ant. I get this error:
    <pre>
    spawn does not allow attributes related to input, output, error, result
    spawn also does not allow timeout
    finally, spawn is not compatible with a nested I/O <redirector>
    </pre>
    This is my Ant target:
    <pre>
    <target name="start_weblogic" description="Start Bea Weblogic asynchronously">
    <exec executable="C:\bea\user_projects\domains\FooBar\bin\startWebLogic.cmd"
    dir="C:\bea\user_projects\domains\FooBar"
    failonerror="true"
    spawn="true" />
    </target>
    </pre>
    Why doesn't it work? What Ant script I need to start Bea 9 application server <b>asynchrously</b>?
    I need this for our Daily Build. In the middle of the automatical building process the application server needs to be started <b>automatically</b>.
