Produce healthy guiding messages instead of cryptic errors and recommend a way out.

Would be helpful if README.md would include link to https://github.com/martinpaljak/oracle_javacard_sdks repository.
Currently the reader has to figure out himself what does /path/to/jckit_dir1 means and where to get it.
The example build.xml can also be updated to include jckit="oracle_javacard_sdks/jc222_kit/".

Tried to build with 1.6, 1.7 and 1.8 JDK's as well as JavaCard SDK 2.1.2, 2.2.1, 2.2.2, 3.0.4. Always with the same error on conversion (OS X 10.11.5):

  error: TestApplet: unhandled bytecode arraylength in clinit method, try a different compiler.
  error: TestApplet:unhandled bytecode i2b in clinit method, try a different compiler.

There is no static initializer in the applet.
Any idea what could be going wrong?

     <javacard jckit="ext/java_card_kit-2_2_2">
        <cap aid="00:00:00:00" version="3.5" output="applet.cap" classes="tmp">
            <applet class="applet.applet" aid="00:00:00:00"/>
            <import exps="ext/visa_openplatform-2_0" jar="ext/visa_openplatform-2_0/visaop20.jar"/>
        </cap>
     </javacard>

Gives error

[javacard] JavaCard SDK folder ext/java_card_kit-2_2_2 does not exist!
and
[cap] error: export file openplatform.exp of package visa.openplatform not found.

In my usage I am trying to specify java 1.5 as the compiler option. In the documentation, it mentions that javaversion should be an option of the cap tag in the build.xml file.

I have tried setting this at other levels (e.g. at taskdef or javacard), but neither option seems to work. I am sure that I am missing something obvious, but not sure what.

It would be nice to have a feature allowing use of the proguard obfuscator. Doing so generally saves a lot of space, and it can also be used to combine library packages. For some uses the obfuscation itself might also be useful.

Currently I do this manually in ant files such as this one:
https://github.com/promovicz/javacard-ndef/blob/master/build.xml

if JC_HOME is set and usable and javacard jckit attribute is missing or not usable, use JC_HOME as JavaCard SDK home folder

I got this error while verifying CAP file, but it was successfully compiling the source into CAP file.... 😄

My OS and IDE detail:
-> Windows 10 Enterprise v1607 x64
-> Java Card SDK 2.2.2
-> Eclipse Neon.3
-> Ant-Javacard v1.7 (latest)

My build.xml:

My build result:

I think there is a problem with whitespace-issue because it only shows C:\Users\Jeffry instead of C:\Users\Jeffry Angtoni...

Getting "unsupported int type of intermediate value, must cast intermediate value to type short or byte". I am able to compile using Java Card 3 Platform Development Kit but not with ant-javacard. The problem looks like related to compiler cmd parameters. The class files generated by Java Card 3 Platform Development Kit are different in size(applet.class is 34kb from jcde and 21kb from ant-javacard) compared to ant-javacard. Is there a document pointing to recommended JAVAC cmd parameters.

When building a cap everything works fine with JCDK 3.0.3 that I'm testing but the generated Header.cap component does not include a name (The package_name_info from the CAP file format specification has length 0). I see the same behavior if I use the regular ant tools so probably it is related to the internal converter but I wonder if is worth trying to fix that in this project. If so, I can have a look if someone can provide some guidance where to look to fix that.

We can include feature which can Convert Cap to IJC file to be loaded onto card. As IJC is much lighter version to be used on real card.
I have complete the code to convert cap to ijc, If you are okay we can integrate with current code.

Using the ant-javacard jar to build our CAP files, it now generates a lot of different errors and doesn't compile the cap. But everything is OK when using the previous version.

I spent some time to figure out what's wrong, and ultimately using the previous version, it works well, as before.

I use JDK 8 (1.8.0).

With jckit/targetkit = 3.0.5u4/3.0.5u4, I got something like that :

When using v21.12.31, everything works fine, our cap is compiled and verified in both cases.
That suggests there are some regressions in the 23.04.03 latest release.

I have two jar files with .exp files (USIM.jar and uicc.jar) to build an USIM applet.
This is the snippet of my build.xml

    <javacard>
      <cap jckit="ext/ant/sdks/jc305u3_kit"
           aid="f2:76:a2:88:bc:fb:a6:9d:34:f3:10"

        <import jar="USIM-API.jar:uicc.jar"/>
      </cap>
    </javacard>

It compiles OK. But converter fails unless I explicitly extract .exp files from above jars and put them in a directory and define import target with both jar and exps attributes.

See #14

Hi

I am using JDK 8 and javac -1.8. I also tried with JDK 11
I try to convert the file to a .CAP file but every time I run ant I receive the following error : error: unsupported class file format of version 52.0.
Here is a snippet of my error :

Also, here is a snippet of my build.xml. I tried several versions of the SDK.

Thank you!

3.1b43 includes new format export files. How to handle targetsdk in such cases in automatic and useful way?

While testing the javacardos jcide, I got an error when building my applet:
com.sun.javacard.offcardverifier.bf: the number of interface for the class or interface XXX is incoherent with the number of the same class or same interface than the class component.

I was able to trigger the problem by not inheriting an interface.
Not OK:
public class MyPIN extends OwnerPIN {
OK:
public class MyPIN extends OwnerPIN implements PIN {

But when built under ant-javacard, no error is shown.
=> is ant-javacard really runing offcardverifier like the sdk built ?

How do you install "LibraryUser_01020304050607_JCv2.2.2.cap"?

If I install the cap file directly, I get:
LOAD failed: 0x6438

So I tried to install "testapplets.library.cap" first (which works), then install the "LibraryUser_01020304050607_JCv2.2.2.cap", I get:
CAP loaded
INSTALL [for install and make selectable] failed: 0x6985 (Conditions of use not satisfied)

thanks!

It looks like classes generated with the StringPool and StringDef annotations aren't reachable from the annotated class, and tests don't cover this “edge” case:

If the stringdefs test case included a call to HelloWorldString.importLibConstants or tried to access any of the created fields from the applet's class constructor, the build process would fail:

Hello Mr. Paljak,

I stumbled upon a problem that seems to be located in ant-javacard.jar. Unfortunately I am not an expert in Java/ANT, but I hope you find the following helpful anyway.

For testing I am using the HelloSTK2 from Merlin Chlosta
git clone https://github.com/mrlnc/HelloSTK2.git

When I leave everything unchanged (except running "git submodule update --init --recursive" beforehand to get the javacard SDKs) and use the latest ant-javacard.jar ANT task (see also build.xml), I get the following:

Best regards.

Currently the Sun/Oracle CAP generator inserts a timestamp in the CAP-file manifest that makes builds non-reproducible.

It should be possible to fix this in a generic and reusable manner by re-generating the JAR with this attribute squashed.

Apart from this little issue the tools involved seem to behave reproducibly already.

Great tool! Thanks for making it!

The current version in https://mvnrepository.com/artifact/com.github.martinpaljak/ant-javacard (18.07.12) still does not support the targetsdk parameter in the cap tag, I guess it is lagging behind the one on github. Could you push up the very latest version?

For reference: #26 (comment)
First of all, I am new to JavaCards and not experienced with java build tools, so far.

"Java Compiler Compliance" is used to compile for a JVM, which does not support the recent class file format, right? https://stackoverflow.com/questions/22584427/what-is-compiler-compliance-level-in-eclipse

Real cards or a simulator may have a compliance level lower than the compiler, but we have to make sure it runs properly.

Sometimes the JCOP tools have hard time compiling/producing your applets (everything works fine, but the CAP file is not produced and cannot be uploaded to the card). The Java language compatibility needs to be set up properly for the Java Card project. In project properties in Eclipse chose "Java compiler" and set "Compiler compliance level" to 1.3 (this should be the safest).

Source: https://www.cs.ru.nl/E.Poll/hw/practical.html

I found similar configuration in this gradle build file. github-af/SmartPGP@9955dd9

Why do you think this option is obsolete?

When creating a cap file from classes, then class files are copied into the cap to the wrong location.

<!-- Extract class files for biometry interface and create .cap file -->
<unjar src="${basedir}/${jcsdk}/lib/api_classic.jar" dest="${class.folder}">
    <patternset>
        <include name="javacardx/biometry/*.class" />
    </patternset>
</unjar>

<javacard jckit="${jcsdk}">
    <cap aid="A0000000620202" package="javacardx.biometry" classes="${class.folder}" output="${release.folder}/biometry.cap" version="1.3" verify="false" />
</javacard>

creates a cap file with

Hello,

I have a modified version of PivApplet that I am trying to add JUnit tests to. I have some test code that's not intended to be part of the .cap, and I'm trying to exclude it using the excludes attribute.

    <javacard>
      <cap aid="a0:00:00:03:08:00:00:10" output="bin/PivApplet.cap" sources="src-gen" excludes="**Test**" classes="bin" version="1.0">
        <applet class="net.cooperi.pivapplet.PivApplet" aid="a0:00:00:03:08:00:00:10:00:01:00"/>
      </cap>
    </javacard>

I've tried every variation I can come up with in order to exclude "src-gen/org/openphysical/pivapplet/PivAppletTest.java". I've tried **Test**, **/*Test.java, etc. I've even tried excluding ".class", ".java", etc. just to see if it would exclude other files.

Does the excludes attribute work? It's entirely possible I'm using it wrong.

I have the following toy code for a library package with a static array:

package testapplets.library;
import javacard.security.RandomData;

public class SomeLibrary {
	public static final short TRUE = (short) 0x5AA5;
	public static final short FALSE = (short) 0xA55A;

	public static final byte[] test = { 'a', 'b', 'c'};

	public static short booleantest(boolean b) {
	        return b ? TRUE : FALSE;
	}

	public static RandomData getRandom() {
		return RandomData.getInstance(RandomData.ALG_SECURE_RANDOM);
	}
}

and the following ant task to build the library package:

  <target name="libtest" depends="prepare">

but I am getting the following error message:

  [convert]     
  [convert] [ INFO: ] conversion completed with 1 errors and 0 warnings.
  [convert] error:  Static array initialization in class testapplets/library/SomeLibrary in library package not allowed.

Why is static array in a library problematic? builds fine if I remove the static array

Hello,

have you considered uploading this to the maven central repository?

It would be great!

Thanks

property has higher precedence than environment

• While the last supported JDK version is 17, make sure the java code also cleanly compiles with JDK 21.

[compile] error: Source option 1.5 is no longer supported. Use 1.6 or later.
[compile] error: Target option 1.5 is no longer supported. Use 1.6 or later.

change this to 1.6 will solve the issue

Is it possible to hide these warnings when the build.xml explicitely contains ints=true ?

Hello,

I got an error when using multiple imports with the same folderpath.

I did some modifications to source code to support it. I tried to do a branch to push my modifications but I don't have the rights. Is there a prefered way to share modifications ?

Cheers and thanks for this wonderful project that saved me hours of coding ;-)

Hello,

I have some JavaCard running on version 2.2 and 2.3. What is the best practive ? I have to use the SDK 305u1 or the 222 ? Both running on my cards, but the CAP file is twice bigger with the 305u1 (12kB against 5kB).

Is new version is more secure and fix issue ?

Sincerly.

I am trying to use the ant-javacard and every time I run it I receive the following error: invalid AID 1.0. ( or whatever version I am specifying ) .

Here is a snippet of my build.xml

Could you please point me in the right direction regarding the AID problem? Thank you!

Hi,

I am using your libs and would like to bump to the v20 but they are not released in the maven central yet. Do you pls plan to submit it there?

Thanks!

Settings:

  <get src="https://github.com/martinpaljak/ant-javacard/releases/latest/download/ant-javacard.jar" dest="./build" skipexisting="true"/>
  <taskdef name="javacard" classname="pro.javacard.ant.JavaCard" classpath="./build/ant-javacard.jar"/>

    <javacard jckit="./sdks/jc305u4_kit">
     <cap targetsdk="./sdks/jc222_kit" ...>
....

Seems like the library doesn't support lambda expression.
