ANT: optional tasks?
How can I make ANT to support optional tasks (a task which typically requires an external library)?
Documentation says:
"If you want to develop extensions to Ant via the Apache Ant API within JDeveloper, see the Extension Manager page in Tools | Preferences - Extension Manager and the Apache Ant API documentation."
I'd love to simply dump the external library (eg junit.jar) in a lib/ext/ant folder...
I find it unfortunate that "add this to the project classpath" has become the de-facto standard solution to class finding and loading issues. Optional JARs contain ANT-specific support classes, and have nothing to do with the project code itself, so why pollute the project's classpath with those libraries?
Like OC4J, ANT should have its own dedicated and customizable classpath, which should initially be cleaned of anything it doesn't need, especially the project's output path. ANT has an IDE-independent way to handle paths. If I want my project's output path to be part of ANT's classpath, then that should be my choice, not JDeveloper's!
If you are in need of inspiration, take a look at Eclipse's ANT integration... no offense intended!

I've been trying to get the optional ftp task for a few days with no luck. I believe I have placed my jar files in the correct place (they show up) but it still says ftp is unavailable. Is there some other step I'm missing? Maybe one of you guys can quickly tell me what's wrong with my set up. Here it the output from ant -diagnostics

Use of Separated Variable in Optional Tasks- Null Pointer Exception
Hi,
I'm facing a strange issue with Object Category as 'Separated'. In our Process the main object(objLaunch) is big in size so we have decided to make object category to be separated. Process flow's each and every interactive activity has an optional task which is a Screen Flow. When we have changed the object(objLaunch) category to be 'Separated' we are getting below error when we had accessed the optional task. Please note that we are facing this issue in
PROD environment where as in studio we are not facing this issue. The same object is present in the main process flow as well as in the screenflow(optional task). This object is passed as an input argument to the screenflow from the main process. In the screenflow as well as the main process, we have made the object as separated, though in the screenflow, upon saving and reopening the category still displays as Normal.

Is it not possible to use separated variables in screenflows which will be accessed as optional tasks? The same screenflow forms part of the main process as well. This activity works fine even after the object was made separated. The error is encountered only in the optional task.
Please could you analyze the mentioned issue and let us know the reason for the error.
Anticipating for your response.
Thanks in advance
~Kavitha APlease could you respond.

Jvmargs not being placed in jnlp file by ant deploy task
Hi
I have an ant deploy task as given below. I run ant to produce the jnlp file. Everything works ok, EXCEPT the jvmargs, and the enclosing platform element, are not copied into the jnlp file.
Is this the intended behaviour?

How to call imported ant target/task in Java
Hi,
Can anybody advice me how to call an ant target/task, which is
"<import/>"ed from another build file, from within Java code?
Here's my Java code:
import org.apache.tools.ant.*;
import java.io.*;
import java.util.*;
public class MyTest
private Project project;
public void init(String buildFile, String baseDir) throws
Exception
project = new Project();
try { project.init(); }
catch (BuildException e)
{ throw new Exception("The default task list could not be
loaded."
// Set the base directory. If none is given, "." is used.
if (_baseDir == null) _baseDir=new String(".");
try { project.setBasedir(_baseDir); }
catch (BuildException e)
{ throw new Exception("The given basedir doesn't exist, or
isn't a directory."); }
if (_buildFile == null) _buildFile=new String("a.xml");
try { ProjectHelper.getProjectHelper().parse(project, new
File(_buildFile)); }
catch (BuildException e)
{ throw new Exception("Configuration file "+_buildFile+" is
invalid, or cannot be read."); }
public void runTarget(String _target) throws Exception
// Test if the project exists
if (project == null) throw new Exception("No target can be
launched because the project has not been initialized. Please call the
'init' method first !");
// If no target is specified, run the default one.
if (_target == null) _target = project.getDefaultTarget();
// Run the target
try { project.executeTarget(_target); }
catch (Exception e)
{ throw new Exception(e.getMessage()); }
public static void main(String args[])
try{
MyTest mytest=new MyTest();
mytest.init("c.xml",".");
mytest.runTarget(null);
}catch(Exception e)
e.printStackTrace();
Here are my build files: (they look almost the same. But it's only to see if <import> works.)
1.c.xml:
<project basedir="." default="runtests" name="TestC">
<import file="a.xml"/>
</project>
2. a.xml:
<project basedir="." default="runtests" name="TestA">
<target name="runtests" depends="">
<mkdir dir="ttt"/>
</target>
</project>
If I directly set build file "a.xml" in MyTest.java, everthing works
well. However, if set "c.xml" then do task "<mkdir dir="ttt"/>" defined
in "a.xml" which was imported by "c.xml", when running, I got an
exception. Looks like it can't parse my c.xml which include "import".
BTW, I'm using ant 1.6.2, and running "ant -f c.xml" was ok.
Did I miss any classpath or something? Any idea?
Thanks,
AmyI have a standard Ant build script for signing a jar file. I import it into my master Ant build files with
<import file="Sign.xml"/>
and then in my master Ant script I setup the name of the jar file e.g.
<property name="jar-file" value="${fun}/FunApplet.jar"/>
and then invoke a target
<target name="sign-jar" depends="jar, sign">
</target>
Since this target (sign-jar) depends on target 'jar' and target 'sign' it executes the 'jar' target and then the 'sign' target that is contained in Sign.xml. -
Optional Task in Interactive Activity usage?
Hi Gurus,
BPM version : 10.3.2
You will be appreciated if some could explain about the optional tasks in the Interactive activity? and how can I execute the same using PAPI?
Thanks in advance.
-NarasimhaHi Ritu,
I'm guessing you might have logic inside your Interactive activity that looks like this:
input "Enter the customer id: " : customerName
using title = "Customer Information",
buttons = ["Ok", "Cancel"]
returning selectedButton = selectionAlthough I find "input" and "display" statements useful for initial prototyping and some testing, don't take it beyond that. The problem with these statements is that they tie up a thread as long as someone has the input or displayed dialog up. Quickly you'll run out of threads as people march off to lunch with these dialogs left up on their screens. Instead use Screenflows with either JSPs or BPM Object presentations to render information to end users.
In direct answer to your question though, if you're using the input statement (again - don't do this in production) be sure to handle the variable that contains the value of the button clicked. The above logic would be changed to the logic shown below to handle the Cancel button being clicked:
selectedButton as String
input "Enter the customer id: " : customerName
using title = "Customer Information",
buttons = ["Ok", "Cancel"]
returning selectedButton = selection
if selectedButton = "Cancel" then
// action is a predefined variable that is an enumeration used in this case to cancel the user's input
action = CANCEL
endHope this helps,
Dan -
What is the optional task?
If I set the implementation of an interactive activity as external and create a prepare and a commit method, can set the optional task as external as well as create its prepare and commit method?
In the papi, how to indentified the different commit or prepare method?

Required the examples or explanation on "Optional Task" functionality
Hi,
I need to explore the importance and main functionality on “optional task”.
[This option is available @ right click of any Interactive Activity]
Please provide me any one have examples/case studies on the same.

JDK based Pack200 works but not Ant Pack200 Tasks
Hi,
In My project, I was earlier using JDK Toolkit based Pack200 Utility and It was working fine for me. As each time user has to set JDK Bin path (C:\Program Files\Java\jdk1.6.0_02\bin) in System variables to run batch file so I switched to Ant based tasks through (https://java-pack200-ant-task.dev.java.net/ ) for Pack200 but it does not work fine.
I came across Following Issues.
#1. I have around 60 Jar files which earlier I was Repacking / packing through Batch file with Jdk based Pack200 support and it worked fine
Repack:
pack200 repack segment-limit=-1 %(JarFileLocation)\(FileName)
Pack:
pack200 --segment-limit=-1 %(JarFileLocation)\ FileName.pack.gz %(JarFileLocation)\(FileName)
#2. Now I switched to Ant Based Pack200 tasks and used following targets. Repacking goes fine but
At time of Packing, I am getting Exception. �java.lang.SecurityException: SHA digest error�.
I experimented with adding some of Attributes like Effort=1 or 0 but it does not work.
There is no difference what I was doing earlier with Jdk based Pack200 and now with Ant based
Pack200 tasks then why I am getting Exception and how it can be eliminated?

How to get Ant option under windows- Preferences in Eclipse Luna?
Hello Eclipse Support,
I switched from Eclipse Kepler(windows 64-bit) to Eclipse Luna(eclipse-cpp-luna-SR2-win32-x86_64.zip) and I see that Ant option is missing under windows->Preferences.
I tried this way:
I saw there was an Apache ant(eclipse\plugins\org.apache.ant_1.9.2.v201404171502) plugin in Eclipse-Luna package like in Eclipse-Kepler.
I tried to install it through Help->install new software. I was unsuccessful even by giving local path point to the plugin directory of eclipse - it showed error msg stating "could not find file at the location that I had selected"
or
the path from apache-ant website(followed the instructions available in ant website to install).
Could you please let me, whether I am doing wrong and If yes, then what are the right steps to acheive this?
Thanks & Regards,
RashmiHi,
I found the answer within the eclipse forum.
My beginning search was not optimized and so, could not reach this post.

I tried using a lower JDK 1.5.x - but that failed as well (complaining that 1.6 was needed).
Any help will be appreciated.
Rgds/DeepakHi,
Have you find a solution for this problem?
I have exactly the same one. I must build my web-services with some dependence compiled on java 1.6 so I need to use the APT task with a java 1.6 but the problem "Apt task requires Java 1.5+" appear.
Thanks in advance for your answer. -
GWT Testing from Ant Junit task
Hey, gentlemen,
I have a target to create junit task to run arbitrary tests for GWT (GWTTestCase subclasses) from different packages. Task should print test cases output in regular junit format and launch tests according to name format, let's say *TestCase.java from anywhere in the project.
So, the problem is:
I run it through shell command line
java -cp 'CLASSPATHHERE' junit.textui.TestRunner my.package.MyTestCase
successful, as well as from
<java name="junit" class="junit.textui.TestRunner" ...>
</java>
ant target, BUT
When I try to do it with the <junit> task, I CANNOT specify a tool (junit.textui.TestRunner) I want to run it with (no tag or attribute), so it failed to initialize hosted mode server. Specifying it like a regular test cases cannot run... (maybe something wrong with my eyes)
Did anybody work with GWT and test cases? Any opinions? Thanks in advance...When you say you have the junit.jar on the classpath, where did you configure this? In the 10.1.2 release, it needs to be specified in the "Additional Classpath" field of the Project Properties.

Why this WLST script does not work from ant a task
Hi,
The following is my lovely WLST script to disable managed server hostname verification in a cluster environment.
It works perfect if I run it from the OS command line,
java -cp $WL_HOME/server/lib/weblogic.jar sslSetting.py weblogic weblogic t3://localhost:7001
But if I run it from ant task, it never works. Nothing happens, not even any messages. Any idea?
------ sslSetting.py -----------
# Disable HostnameVerification on managed servers
# This is a ONLINE script. The admin server must be running
# @param $1 BEA_USER_NAME
# @param $2 BEA_USER_PWD
# @param $3 admin server URL
if (len(sys.argv) != 4):
print "usage: " + sys.argv[0] + " domain-home "
sys.exit()
beaUserName=sys.argv[1]
beaUserPwd=sys.argv[2]
adminServerUrl=sys.argv[3]
def handleServer(server):
SSLPath="/Servers/" + server.getName() + "/SSL/" + server.getName()
print("handleServer(1): " + SSLPath)
try:
cd (SSLPath)
print("handleServer(2): " + SSLPath)
set("HostnameVerificationIgnored", "true")
except Exception, inst:
dumpStack()
print ("FAILED handleServer(): " + SSLPath)
else:
print ("DONE handleServer(): " + SSLPath)
#===============================================================================
# Main
#===============================================================================
try:
connect(beaUserName, beaUserPwd, adminServerUrl)
edit()
startEdit()
adminServerName=cmo.getAdminServerName()
for server in cmo.getServers():
if adminServerName != server.getName():
handleServer(server)
save()
activate()
except Exception:
dumpStack()
else:
print ("=== DONE ===")OK, when I run the WLST script from command java, I only need the weblogic.jar in the classpath. But I'll need a couple other jar file for it to work inside an ant target, as showing below.
<target name="run-wlst">
<java classname="weblogic.WLST" fork="true">
<classpath>
<pathelement path="${props.JAVA_HOME}/lib/tools.jar"/>
<pathelement path="${props.WL_HOME}/server/lib/weblogic_sp.jar"/>
<pathelement path="${props.WL_HOME}/server/lib/weblogic.jar"/>
<pathelement path="${props.WL_HOME}/server/lib/webservices.jar"/>
</classpath>
<sysproperty key="weblogic.Home" value="${props.WL_HOME}" />
<arg line="sslSetting.py weblogic weblogic t3://localhost:7001"/>
</java>

Hey all,
I am trying to ensure that my ANT scripts are building, jar'ing and obfuscating my java files in java 1.1.8 even though I have 1.4.1 installed on my system. I am having a hard time getting accurate reference on how to force the "java" task to run in 1.1.8. I set fork="true" but don't know how to fork it to a specific VM. My general plan is to.....
1. Build into {$build} directory in 1.1.8
2. Jar the files up using deploy.jar
3. Obfuscate this jar using retroguard
If anyone can help me with this, it would be greatly appreciated. Below are the ANT scripts that I am using. So far the javac command seems to be working properly in 1.1.8, my problems now come from the java command.
<target name="init">
<tstamp/>
<delete dir="${build}"/>
<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init">
<javac srcdir="${src}"
destdir="${build}"
fork="yes"
executable="c:/jdk1.1.8/bin/javac"
compiler="javac1.1"
verbose="yes"
target="1.1"
memorymaximumsize="128m"
memoryinitialsize="128m"
/>
</target>
<target name="makejar" depends="compile">
<java jar="lib/deploy.jar" jvm="javaw" fork="true">
<arg value="-classpath"/>
<arg value="${build}"/>
<arg value="-jar"/>
<arg file="lib/myJarPLAIN.jar"/>
<arg value="-silent"/>
<arg value="org.mypath.MainAppletClass"/>
</java>
</target>
<target name="makeRPJar" depends="ratioprop-dist">
<java classname="RetroGuard" jvm="javaw" fork="true">
<classpath path="lib\retroguard\"/>
<arg line="lib\myJarPLAIN.jar lib\mysrc\myJar.jar lib\myscript.rgs"/>
</java>
</target>
Thanks!
RobI think you're going to have to use exec as opposed to java. The java task uses the same JDK/JRE, though it might use a different command within the JDK/JRE.
It's not that much more difficult, especially if you have all the parameters declared already. -
Java.lang.UnsupportedOperationException coming out of ant jwsc task
Hello!
I'm trying to stand up a simple example web service so that I can 'instrument' it with a QOS monitoring application. (The goal here is to learn to use the monitoring app.) I'm pretty sure that I've got a usable piece of code for a web service; I can use Endpoint.publish and get results, and I copied a test stub I found somewhere to use a QName to test it and that works.
I'm getting the above referenced error coming out of my build.xml file when I try to compile this as a web service inside the WL environment. The error message reads as being generated by line 11 which reads 'destdir="./target/classes" '. It's also got the closing '>' from the '<jwsc' declaration so that is likely why it's this line that's complaining.
The stacktrace references 'Collections.$SingletonSet$.Remove()' which is being called out of jwsctask. It then progresses through jwsLoader and jwsMudule before the stack goes through a bunch of org.apache.tools.ant classes. It's the remove() that's got me worried; I can't find any documentation on SingletonSet as a nested class of Collections, but it's reasonable to think that remove() is actually an UnsupportedOperation. That would mean that I've found a bug as opposed to having just done some stupid newbie thing. I'd much rather be a stupid newbie. :-)
Anything that the collected wisdom could point out to me would be greatly appreciated. TIA
