Using ANT to compile code on AIX.

Can anyone tell me what is te equivalent of Window's CLASSPATH on AIX?
I have a ANT build script that extratcs the source code from CVS repository and compiles everything, creates all the needed JAR, WAR and WAR files. This script executes well on Windows XP but it is not able to compile the classes on AIX. It always asks for Log4j classes as I am using log4j in my application. I have already added the AIX PATH variable with log4j-1.2.8.jar location. Also added this logj JAR file in Java/JDKs lib directory. Nothing seems to work.
What could be the reason? Where am I going wrong? Any help would be appreciated.
Thanks in advance.

A classpath-related portion of a working ant-setup might be useful:
<target name="web-classes" depends="setup">
    <javac srcdir="${javasrc.dir}"
      destdir="${bld.web.dir}/WEB-INF/classes"
      debug="on">
      <classpath>
        <pathelement path="${common.class.path}" />
        <pathelement location="${bld.web.dir}" />
        <pathelement location="${lib.dir}/velocity-1.4.jar" />
        <pathelement location="${lib.dir}/velocity-dep-1.4.jar" />
        <pathelement location="${lib.dir}/bcprov-jdk14-124.jar" />
        <pathelement location="${lib.dir}/commons-fileupload-1.0.jar" />
      </classpath>
    </javac>

Error deploying JDeveloper project using ant-sca-compile.xml

Hi all, I'm having problems on deploying a JDeveloper project using ant-sca-compile.xml. The output in C:\XXXX\YYYYY\SCA-INF\classes\scac.log is:

Same composite we were able to deploy successfully without any error, from Monday onward we are experiencing this issue.
We checked in Installation Guide provided by oracle. Oracle has suggested few memory related changes in ant-sca-compile.xml file.
Increasing Memory to avoid Compilation Errors
To avoid out-of-memory errors during compilation of a SOA composite application, you need to
increase the following memory settings.
To increase memory settings:
1. Open the ant-sca-compile.xml file in the SOA_HOME/bin directory.
2. Under the scac element, increase the following memory settings.
<jvmarg value="-Xms2048m"/>
<jvmarg value="-Xmx2048m"/>
<jvmarg value="-XX:PermSize=32m"/>
<jvmarg value="-XX:MaxPermSize=256m"/>
3. For Windows change the following memory settings to.
<jvmarg value="-Xms1536m"/>
<jvmarg value="-Xmx1536m"/>
<jvmarg value="-XX:PermSize=32m"/>
<jvmarg value="-XX:MaxPermSize=256m"/>
We did those changes but still experiencing same error. I checked H:\AIASOAProject\AIAReceiptInterface\ReceiptListEbizProvider\SCA-INF\classes\scac.log ; file its showing Could not create the Java virtual machine.

"Error running javac.exe compiler" when using ant to compile Eclipse plugin

Hi
I encounter an error "Error running C:\jdk1.5.0_06\bin\javac.exe compiler" when building my project using ant1.7.
My project has 10 eclipse plugins, and each plugin is compiled by invoking following ant target

<target name="compilePlugin">
     
     
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
     
     <delete file="${param.plugin.dir}/${param.plugin.targetJarFile}" quiet="true"/>
     <mkdir dir="${param.plugin.dir}/${build.dir}"/>
     
     <javac      srcdir="${param.plugin.dir}/${param.plugin.src.dir}"
               destdir="${param.plugin.dir}/${build.dir}"
               failonerror="${javacFailOnError}"
               verbose="${javacVerbose}"
               debug="${javacDebugInfo}"
               deprecation="${javacDeprecation}"
          optimize="${javacOptimize}"
               source="${javacSource}"
               target="${javacTarget}"
               fork="${param.fork}" memoryInitialSize="256m" memoryMaximumSize="512m">
          <classpath refid="compile.classpath" />
     </javac>
     
     <copy todir="${param.plugin.dir}/${build.dir}" failonerror="true">
          <fileset dir="${param.plugin.dir}/${param.plugin.src.dir}" excludes="**/*.java, **/package.htm*" />
     </copy>
     <jar jarfile="${param.plugin.dir}/${param.plugin.targetJarFile}" basedir="${param.plugin.dir}/${build.dir}"/>
     <delete dir="${param.plugin.dir}/${build.dir}" quiet="true"/>
</target>
Since each of first 9 plugins contains less than 500 java source files, we always set "param.fork" to false when invoking this ant target.
For the 10th plugin, it has about 1000 source files. If we set "param.fork" to false, we will get the error "Error running javac.exe compiler". So we have to set "param.fork" to true when compiling it. This week, this plugin contains about 1250 files and we get the same error again when compiling it. I tried to increase the "memoryMaximumSize" to "768", but still couldn't get through it.
BTW, There are about 150 jar files in our classpath for compiling plugins. Do many jar files cause this problem?
Any help is highly appreciated.
Many thanks
Oceanman

I encountered a very similar error and I was able to resolve it by removing the following parameters from the javac task:
fork="${param.fork}"
memoryInitialSize="256m"
memoryMaximumSize="512m"My values were not the same as yours, before I removed them, the values were set to:
fork="true"
memoryInitialSize="256m"
memoryMaximumSize="256m" Not sure why this fixed my problem but it did. I was using Ant 1.7 and Java 1.6_07 hope this helps.

JSP precompilation and my .java files compilation issues / building WAR file using ANT

Hello.
I am new to working with WAR files and the whole process of it. A little
background on what we are using. We are using, WLS 6.1 SP3. I am using the
ant.bat that is supplied in the bin directory of the WLS install.
I am trying to work with ANT and getting it to build the file. I am making
progress, but at a point where I am having trouble getting my java code
files to compile using ant. I am having one issue and looking to do one
other item.
1) I would like to precompile the JSPs if possible prior to putting into the
WAR file. Not sure if this is done or not, but there was a utility when I
was working with ibm's app server that gave us the ability to do a batch
complile. Was thinking that maybe a similair concept is possibly here.
2) Having issue getting ant to compile code properly. In the compile
section of the build.xml file for ant, I tell it where the source files are,
and the destionation folder for the compiled class files. I then try to set
the classpath so that it finds the .jar files that are necessary for my
source files to complile. But, it won't find them. And not sure how come.
I may be going about this all wrong, but dont know. Here is the compile
section of the build.xml I am using:
<target name="compile" depends="prepare">
<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
classpath="$(lib.home)"
debug="on" optimize="on" deprecation="off"/>
</target>
One note, I've tried many different items in the classpath line, which
don't work. if I do *.jar it fails at complie time, invalid argument. As
well as if I use *.* and so on. if I list the explicit file names, it still
doesn't seem to find them.
I was wondering if anyone could help, if you need anymore information let me
know, I can send the entire build.xml if necessary. I may be missing
items, seeing that this is my first try at using ANT.
Any help is appreciated and thanks in advance. Hopefully not sounding too
off the wall. Hopefully get some clarification and understanding.
Thank you.
Kevin.

http://e-docs.bea.com/wls/docs70/jsp/reference.html#57794
or just set the precompile flag in weblogic.xml
You can configure WebLogic Server to precompile your JSPs when a Web
Application is deployed or re-deployed or when WebLogic Server starts up
by setting the precompile parameter to true in the <jsp-descriptor>
element of the weblogic.xml deployment descriptor.

maybe because you are not using curly braces there on lib.home??
if you do it the way above, you would have to list all your jars
classpath="$(lib.home)\lib1.jar:$(lib.home)\lib2.jar"

<javac srcdir="classes" destdir="${deploy.home}/WEB-INF/classes"
debug="on" optimize="on" deprecation="off">

An interesting discovery of ant javac compile task

hi all
i just found out a new thing about using ant to compile java classes, at least it is new to me. you can use ant to compile classes even if they are not in the correct physical path which are indicated in the package declaration. i.e. if you have a class :
package com.name1.name2
class SomeClass{
}and, if the java file is atually located in com/name1/name2/name3, the ant can still compile it and place the binary class anywhere u specify.
any comment on this?

thanks, i suppose javac will place the class file in
proper place with the information from the package
declaration. if it is declared for this package,
then it will be compiled and place in that folder
accordinglyYep. Relative to current directory, or to the directory specified by -d if present.
. interesting, i never knew that until
now. but this wuoldn't work if you want to use an IDE
tool to develop. i tried with eclipse, and it
complained about the package problem and treated it
as an error.That's probably eclipse being deliberately stricter than javac. Personally, I can't see any good reason not to put them in their respective package directories in the first place.

Error when using ant

When I use ant to compile, I always get this message:
C:\WINDOWS\system32\ntvdm.exe

Never mind. I was using an old version of ant (1.3) and I downloaded the newest one (1.5) and it works fine now.

Using Ant to deploy manually

Hi,
I am hoping that someone can point to the correct documentation regarding using Ant to compile and deploy a BPEL process.
I am attempting to deploy a BPEL flow in a test environment from the command line. I have copied the BPEL flow project to the BPEL SOA server (HP Linux, BPEL version 10.1.3.1), but I do not think I have my environment variables set up correctly.
What environment variables need to be defined? Also, in the ant command syntax how do I specify the revision/version number of the flow?
The following is transcript from a session showing the various errors and the variables I have set:
[bpel@omv1rrm2 test]$ ant
-bash: ant: command not found
[bpel@omv1rrm2 test]$ export PATH=$PATH:$BPEL/ant/bin
[bpel@omv1rrm2 test]$
[bpel@omv1rrm2 test]$ ant
Error: JAVA_HOME is not defined correctly.
We cannot execute java
[bpel@omv1rrm2 test]$

[bpel@omv1rrm2 test]$ ant
Buildfile: build.xml does not exist!
Build failed
[bpel@omv1rrm2 test]$ cd ManageVoiceMail/

[bpel@omv1rrm2 ManageVoiceMail]$

You need to set bpel_home, oracle_home and ant_home, add you ant home/bin directory to PATH. Also add all the required jar files in classpath. Then you can run your ant command.
For bpel process revision, in build.xml pls check the sections "Compiling bpel process ${process.name}, revision ${rev}" and "eploying bpel process ${process.name} on ${http.hostname}, port ${http.port}" for compiling and deploying bpel processes. In that section the revision is read from property ${rev} and it is read from your build.properties(or you build property) file.
I could not find specific documentation that I can point you out. Perhaps the previous discussions in this forum can help you more to achieve your task.

How to compile a class from a Servlet using ant!!!

Hi I have the following problem:
I have a Servlet that must compile a java class.
Here is the code that i use to compile:
File buildFile = new File(build.xml path);
String[] arg = { "-buildfile", buildFile.toString(), "compile" };
Properties userProps = null;
ClassLoader loader = ClassLoader.getSystemClassLoader();
Main.start(arg, userProps, loader);
The build.xml file was written correctly, infact if i lunch the command ant by dos it is correctly done.
When I put my application in tomcat/webapps and try to compile with code above I have the following error:
BUILD FAILED C:\......: Could not create task or type of type: property.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'property'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries implementing the functionality were not found at the time you yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the task and make sure it contains more than merely a META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task and needs to be declared using <taskdef>.
- You are attempting to use a task defined using <presetdef> or <macrodef> but have spelt wrong or not defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented in ANT_HOME/lib, the files must be in the same directory or on the classpath
Please neither file bug reports on this problem, nor email the Ant mailing lists, until all of these causes have been explored, as this is not an Ant bug.

How to compile Java files using Ant in Eclipse

Hi All ,
I would like to compile all Java files using Ant in Eclipse.Since am very new to Ant and Eclipse can someone help me to create a build.xml file and let me know how to compile all the java files.
For ex , I have placed my java files inside the path C:\HEC\Terab.Initially the Terab folder holds 7 jar files which i had decompiled using JD compiler and placed the unzipped 7 folders (which contains the java files ).Now i have imported the HEC project into Eclipse using New ->Project ->Java Project.after importig it throwed me an error saying missing jar files.again i copied the jar files and placed inside Terab folder with other 7 folder.
Now How i can compile the java files and convert in to class files.Then after compiling the files i will again need to jar all the 7 folder.
Please tell me the steps i need to follow.How to write an build.xml file ? where i should keep it ? only one build.xml file is enough or should i write 7 build.xml file for each folder ? Please help me out...
Thanks & Regards

OK, I checked my build script and remember having this problem. I'm deploying a war file that contains some java EE and flex code. So my solutions does not apply to your case, but check out this blog post.

Compiling with JRockit using ant

I am considering switching to JRockit.
Our java code is compiled using ant, with the 'javac' task.
The javac task has an option to invoke different compilers:
- classic (the standard compiler of JDK 1.1/1.2) – javac1.1 and javac1.2 can be used as aliases.
- modern (the standard compiler of JDK 1.3/1.4/1.5/1.6) – javac1.3 and javac1.4 and javac1.5 and javac1.6 can be used as aliases.
- jikes (the Jikes compiler).
etc
The Jrockit compiler is not on this list.
I have found a suggestion (http://www2.sys-con.com/ITSG/virtualcd/Java/archives/0811/pepperdine/index.html) to use an exec call as a workaround,
but are there any alternatives? I could perhaps persuade ant to use JRockit by deinstalling any other JDK's and pointing JAVA_HOME to JRockit;
what I want however is to keep the option to use different compilers.
Has anyone got any suggestions?

The javac compiler bundled with JRockit is the exact same one that you get with the Sun JDK. Oracle licenses the JDK (class libraries, tools, etc) from Sun. So I would just set JAVA_HOME to point at JRockit as you suggest.

Problem compiling in Linux using ant

Hi,
I have a problem using ant in Linux.
When I build my application using ant in Windows it works fine, but when I try to build the same application with ant in Linux it gives me the following exception:
/identifier/MidiReader.java:5: error: Class or interface `javax.sound.midi.Sequence' not found in import.
I have already checked and the 'javax.sound.midi.Sequence' exists in import.
Can anybody help me?
Regards,
David

In your javac task (in Ant), you need to explicitly include any external JAR's required for compilation (see ant.apache.org's docs for info). Importing them in a Java source file does not tell Ant where to locate the JAR for linking.
