Problems with Box.com Invoice Demo on Tomcat

[mathiasconradt]

I try to setup the Box.com demo and followed the instructions, but cannot get it to work properly.

Using Camunda BPM 7.8.0 CE (latest available CE I downloaded today).

I created a box.com app (actually, I tried with two: a custom app and a partner app, because I wasn't sure if it makes a difference.) using OAuth2.0 with JWT.

I configured the config.properties and saved the private_key.pem that I got from the box.com app admin interface, then built the camunda-example-invoice-box app with maven, which built the war file just fine, and deployed it. (I tried with both approaches: deploying the war file, and also deploying the exploded folder under the target directory.)

When going into the Camunda Tasklist, I do see the box window, but there are some issues:

1. the icon b.png is missing

2. clicking on the "Open Box Folder" doesn't do anything, and I am not sure what the html/target should look like, or if there is a click event handler supposed to be associated with this link. All that happens is that the same Camunda windows re-opens again in a new browser tab. But not box folder in sight.
   I noticed that the <a> has on href nor id. Not sure if this is supposed to be like that.

An additional question which I would like to clarify: is the boxUserId parameter in the config.properties supposed to be the box userId, or the enterpriseId. Just to be sure, because app settings json in the console shows just the enterpriseId ?

I'm also interested in this topic. Thanks.

I started off with a new clean database, to be sure that the original invoice process and the box invoice process does not get mixed. I think that was one of the issues mentioned above (issue 2.)

I also made sure that only the camunda-example-invoice-box application is deployed and not the camunda-example-invoice application. I also cleared all relevant files under <tomcat>/work/Catalina/localhost/camunda-example-invoice*

Nevertheless, when I now want to start a new box invoice process, there are a few 404 errors, i.e. when selecting a local document and trying to upload it, the REST API at http://localhost:8080/camunda-invoice-box/rest/rest/upload as well as the icon http://localhost:8080/camunda-invoice-box/assets/img/ajax-loader.gif cannot be found.

Update:

I found the reason for the images not being found: in the html forms, the path is hardcoded to /camunda-invoice-box/..., while the example application is called camunda-example-invoice-box due to the artifactId in pom.xml. Note the example in the name.

<artifactId>camunda-example-invoice-box</artifactId>

However, the /rest/upload still fails with a 404. This is on Camunda 7.8.0 CE as well as EE with Tomcat.

Also related: #40

Update 2:

I just tried with Camunda EE 7.8.0 with WildFly 10. On there, I don't get a 404 when calling POST /rest/upload but a 505 instead:

org.jboss.resteasy.spi.UnhandledException: java.lang.ClassCastException: org.bouncycastle.pkcs.PKCS8EncryptedPrivateKeyInfo cannot be cast to org.bouncycastle.openssl.PEMKeyPair

Hi @mathiasconradt
this example was only tested on Wildfly.
So I will leave this ticket open, so we can fix it for tomcat.

The second issue you are mentioning is probably an issue with the box.com api that needs a specific JDK extension.
I remember this one here: http://www.oracle.com/technetwork/java/javase/downloads/jce-7-download-432124.html & https://github.com/box/box-java-sdk#quickstart

Hope this helps.

@felix-mueller Confirming, it's working fine on Wildfly.
