struts2 error com.opensymphony.xwork2.util.finder.DefaultClassFinder

Question

I am using struts2 for a project. Users can request to download files from a web page and this request will be processed on background. In order to make it work, I have to create a dispatcher which needs to pass in a servletContext object.

//MockServletContext comes from the spring framework
MockServletContext context = new MockServletContext("file:directory");
//Initialize a dispatcher
StrutsTestCaseHelper.initDispatcher(context, map);

My log file outputs a bunch of errors and one example for "unable to read class" exception:

ERROR [com.opensymphony.xwork2.util.finder.DefaultClassFinder] - Unable to read class [one.action.class.path]

There is another kind of exception:

java.io.FileNotFoundException: class path resource [one/resource/path/resource] cannot be resolved to absolute file path because it does not reside in the file system: jar:file:/home/user/dev/project/build_output/splice_links/da39a3ee5e6b4b0d3255bfef95601890afd80709/resources/resource.jar!one/resource/path/resource

I read a lot of posts on stack-overflow but none of them helped me. Do I need to add some configurations to MockServletContext. May anyone tell me how I could fix this error. If you need me to post more files/information, please let me know.

asm dependency in pom.xml :

 <dependency>
  <groupId>org.ow2.asm</groupId>
  <artifactId>asm</artifactId>
  <version>5.0.3</version>
</dependency>

With the following error,

java.lang.ArrayIndexOutOfBoundsException: 10792
    at org.objectweb.asm.ClassReader.readClass(Unknown Source)

I think, you need to check if you are using the correct version of asm jar file in your project.

what version of asm jar should I use? – user3369592 Jan 18 '18 at 18:31
ok, we had a similar problem. It has also to do with the JDK and the Spring version. [this](https://stackoverflow.com/questions/26496338/strange-java-lang-arrayindexoutofboundsexception-thrown-on-jetty-startup) post helped us to resolve it. – amdg Jan 19 '18 at 05:37
@amdgare you using java 8? I have to use java 8. – user3369592 Jan 19 '18 at 23:30
