Seems to be related to #755.

Can you post your classpath please? Did you include ALL of the EpubCheck dependencies inyour project?

[epubreader]

I am using spring boot, run the program in the jar file, java -jar app.jar

jar:file:/app.jar!/BOOT-INF/lib/epubcheck-4.0.2.jar!/com/adobe/epubcheck/schema/30/./multiple-renditions/container.rnc

ResourceUtil

public static String getResourcePath(String localName) {
    String classPath = ResourceUtil.class.getName().replace('.', '/');
    String classPackage = classPath.substring(0, classPath.lastIndexOf("/"));
    String projectPackage = classPackage.substring(0, classPackage.lastIndexOf("/"));
    return projectPackage + "/" + localName;
}

[tofi86]

You did not include the EpubCheck dependencies in your classpath.

If you download EpubCheck ZIP from the releases page https://github.com/IDPF/epubcheck/releases/tag/v4.0.2 you will find a lib/ folder with 13 jar libraries packed along with epubcheck.jar. All those libs need to be placed in your classpath.

Closing this as invalid because it's a configuration error.

[epubreader]

I am using maven, it is fine run in intellij,

    <dependency>
        <groupId>org.idpf</groupId>
        <artifactId>epubcheck</artifactId>
        <version>4.0.2</version>
    </dependency>

but after spring boot generate the fat jar app.jar with all the dependencies, it has this problem, I think it is not the classpath problem.

[tofi86]

I'm not familiar with Spring, but it seems as if the FatJar does not contain all the epubcheck resources.

Can you check that the fatjar contains the schemas app.jar -> com/adobe/epubcheck/schema/30/? If not, the problem is your fatjar processing.

[ctriebstein]

I ran into the exact same issue and haven't found a solution yet.

I checked for the schemas and they are indeed included in the application jar but apparently spring boot is unable to find them.

[tofi86]

Okay, I reopened the issue and someone has to review it and reproduce and debug it. Unfortunately it cannot be me, sorry.

@ctriebstein could you please post your classpath and make sure that all the EpubCheck dependencies are loaded? Probably make sure that the dependencies load before EpubCheck classes?

[ctriebstein]

I added the classpath to the attached file. Dependencies are loaded properly.

For some more information: I'm using a custom implementation of the Report class which I just updated from the 3.0.1 version to 4.0.2. The error occurs when calling the epubCheck.validate() method with the custom report.

If you need any code snippets, let me know.

cp.txt

[ctriebstein]

Additional Info: One of my recent changes was the update from spring boot 14.1-RELEASE to 1.5.1-RELEASE. I just tried a little something and reverted the version to 1.4.1-RELEASE and now it works as intended. Might be a spring boot issue with 1.5.1-RELEASE.

[epubreader]

it is because it is a nested jar, the below code will throw fileNotFoundException

@Test
public void submittingForm() throws Exception {

    URL url = new URL("jar:file:/D:/eclipse/web/target/web-0.0.1-SNAPSHOT.jar!/BOOT-INF/lib/epubcheck-4.0.2.jar!/com/adobe/epubcheck/schema/20/rng/container.rng");
    url.openStream();

}

and please check the code XMLValidator

[rdeltour]

Is this still an issue? To be honest I'm not sure I fully understand the problem here. If this is still causing trouble, could anyone rephrase the issue or provide a clear way to reproduce? Thanks!

[Ridman]

Reproduced with spring boot 1.4.4.RELEASE and 1.4.7.RELEASE. Works well with 1.5.19.RELEASE.

Closing (inactive).
