java XML parsing using jaxb or dom?

I have a following xml file:
<?xml version="1.0" encoding="UTF-8"?>

I need to parse this XML file and assign values to its corresponding class objects.Which is the best option to parse such an xml file.
JAXB sounds good to me but the POJOs were already written by someone and now i will have to rewrite and deploy them.ALso teh xml file has some errors while running xjc command.
DOM approach seems to be very cumbersome n error prone.
Please suggest.
PS:Kindly excuse my beginner level knowledge.

the JDK project comes with SAX(Simple API for XML) accessible by importing org.xml.sax.*.
You may take a look at this https://www.tutorialspoint.com/java_xml/java_sax_parse_document.htm for an introduction to the subject.

Multinesting Gradle Projects in IntelliJ Idea

I am using IntelliJ Idea 14.1.4 and Gradle, and I am trying to create sub projects and nested sub projects:
Project
|--Research
|--Development
|--Algorithms
The reason for this is that research algorithms are separate from the development implementation. They are written in different languages (Python vs. Java) and used by different programmers, however I still want to maintain one Gradle project, so eventually researchers would be able to use stable existing algorithms implementations when developing new ones.
My problem is that Idea doesn't recognize properly the Gradle structure of the second level Gradle sub project: Project is recognized well, Research and Development are recognized well, but the Algorithms sub project is not recognized:
The code inspection of the gradle.build file in Algorithms project is highlighted as a warning with a message that test cannot be applies to Groovy.lang.closure Note that below is the complete build.gradle:
test{
useTestNG()
testLogging.showStandardStreams = true
}
Also, when I try in Idea Run->Edit Configurations->Defaults->Gradle and trying to choose Gradle project, I see that in the pop-up menu Development and Research do appear as sub-projects of Project, but Algorithms appears as a stand alone project.
Making the project however does create all the binaries and manually running a test case also works well.
When I run Gradle for command line, it appears to be working well and recognizing all nested projects: All the code is being compiled and tests are being ran. So the question here is if there is an Idea issue here which is not working correctly with Gradle, or am I doing something wrong?
Code for build.gradle inside Project:
allprojects {
group 'com.project'
version 'v0.1'
repositories {
mavenCentral()
}
}
Code for settings.gradle inside Project
rootProject.name = 'Project'
include 'Development'
include 'Development:Algorithms'
include 'Research'
Code for build.gradle of Development sub-project:
subprojects {
apply plugin: 'java'
repositories {
jcenter()
}
dependencies{
testCompile 'org.testng:testng:6.9.4'
}
}
Other code samples that I might be writing wrong (most of them are auto generated by Idea:

I would like to point the following:
All projects and sub-projects have the same group: com.project
In Algorithms.iml the original (auto generated) value of external.linked.project.id was :Algorithms. I have tried setting it to :Development:Algorithms to see if it will change anything. After each change I have ran rebuild.
In Algorithms.iml the original (auto generated) value of external.root.project.path was $MODULE_DIR$/... I have tried setting it to $MODULE_DIR$/../.. to see if it will change anything. After each change I have ran rebuild.
****************************Edit********************************
Further investigation shows an issue with the workspace.xml file:
There is a GradleLocalSettingsElement there that was automatically created, but appears to be wrong: There are two different entries: one for Development and Devlopment:Algorithms and onw for the rest, so I might have did something wrong when I created the project.
My question is if there is a reference for the structure of this file and specifically for the elements inserted by the Gradle plugin?

ANT - How i cant move File to JAR

i've had edited my ANT build process. Here is my working list:
create a copy of the src folder and a selfwritten AntTask Obfuscated all Strings
ANT creates an JAR with <jar>
the JAR will be Obfuscated by ProGuard
An additional file will must be copied to the JAR
JAR will be signed
The bodled step is my Question. How i can copy a single file to the root directory of the JAR. I must make this step here! Before or after won't work: Before: ProGuard will be try to obfuscate this file and gives Exceptions. After cant work, the file must be signed.
Anyone have an smart idea?
Here a minified version of my ANT build script:

This is a part from my ant build file including all xml, jpg, gif and png:

<javac srcdir="${src.dir}" destdir="${bin.dir}" debug="on" classpathref="javac.classpath" />
<copy todir="${bin.dir}">
<fileset dir="${src.dir}">
<include name="**/*.xml" />
<include name="**/*.jpg" />
<include name="**/*.gif" />
<include name="**/*.png" />
</fileset>
</copy>
</target>
To only include one file just put the full name in include name= "fullnamehere" />
Sorry...haven't seen your part to add...
Try it like this:
include name= "builds/temp/_XA.class" />

Since a Jar is really a Zip file, you could unzip the jar to a temp directory after proguard does its thing, add the _XA.class file where you want in in that temp dir, and re-create the jar file before signing.

Configure the size of the icon at J2ME Polish

How can I configure the size of the icon to fit correctly on the multiple mobile devices?
Based on the J2ME Polish documentation, I'm using the following resources folder structure:
IconSize.15x15\icon.png
IconSize.16x16\icon.png
...
But it's no working, I've tried in several mobile devices and all of them load the default J2ME Polish icon.
Here's my build.xml file:

Java ME application icon is defined on Jad and Manifest keys. It is often informed in both MIDlet-Icon and the second value of MIDlet-1. See this other question about it add icon to j2me application. And also see this other questions on icon sizes Is there a standard icon size and color depth for J2ME?.
On the link you provided http://www.enough.de/products/j2me-polish/documentation/building/resource-handling/resource-assembling.html there is this text: "You can use the IconSize.0x0 for storing icon resources for devices with an unknown IconSize capability"
I suggest you, by my personal experience with icons - not with polish - to add a 32x32 png icon image at this folder.

how to compile ResourceBundle class using build.xml file

I have developed J2ME application.
When I try to compile my application via build.xml file I get below error

You need to check your code in ConfigurationUtil.java
There is a compilation occuring in this file during the build . Fix the error and rebuild it should work .
