Thanks in advance !

@Gigli0neiric create a folder called “templates” in the folder /src/main/resources and move the .ftl files to the templates folder.

Are you using camunda connectors?

Also make sure the below dependency in the classpath:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>

Gigli0neiric · January 28, 2020, 8:07pm

@aravindhrs i created the folder “templates” in the folder /src/main/resources and moved the .ftl files to the templates folder. I also added the dependency. I still get the same error message.

Yes, i’m using connectors.

<camunda:inputParameter name=“soapEnvelope”>
<camunda:script scriptFormat=“freemarker” resource=“templates/soapEnvelope.ftl” />
</camunda:inputParameter>

aravindhrs · January 28, 2020, 8:46pm

@Gigli0neiric include below dependency as well.

<dependency>
  <groupId>org.camunda.connect</groupId>
  <artifactId>camunda-connect-core</artifactId>
</dependency>

You need to configure the connect plugin for the processengine. In order to activate Camunda Connect functionality for a process engine, a process engine plugin has to be registered in $TOMCAT_HOME/conf/bpm-platform.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<bpm-platform ... >
  <process-engine name="default">
    ...
    <plugins>
      ... existing plugins ...
      <plugin>
        <class>org.camunda.connect.plugin.impl.ConnectProcessEnginePlugin</class>
      </plugin>
    </plugins>
    ...
  </process-engine>

</bpm-platform>

Try like below:

    <camunda:connector>
      <camunda:connectorId>soap-http-connector</camunda:connectorId>
      <camunda:inputOutput>

        <camunda:inputParameter name="soapEnvelope">
          <camunda:script scriptFormat="freemarker" resource="soapEnvelope.ftl" />
        </camunda:inputParameter>

        <!-- ... remaining connector config omitted -->

      </camunda:inputOutput>
    </camunda:connector>

Gigli0neiric · January 28, 2020, 9:25pm

@aravindhrs
I also added the dependency

<dependency>
  <groupId>org.camunda.connect</groupId>
  <artifactId>camunda-connect-core</artifactId>
</dependency>

The plugin was already configured in the bpm-platform.xml

<plugin>
        <class>org.camunda.connect.plugin.impl.ConnectProcessEnginePlugin</class>
</plugin>

The connctor is configured like this:

<camunda:connector>
          <camunda:inputOutput>
            <camunda:inputParameter name="url">http://www.thomas-bayer.com/axis2/services/BLZService</camunda:inputParameter>
            <camunda:inputParameter name="headers">
              <camunda:map>
                <camunda:entry key="Content-Type">application/soap+xml;charset=UTF-8;action="http://www.thomasbayer.com/blz/getBank"</camunda:entry>
              </camunda:map>
            </camunda:inputParameter>
            <camunda:inputParameter name="soapEnvelope">
              <camunda:script scriptFormat="freemarker" resource="templates/soapEnvelope.ftl" />
            </camunda:inputParameter>
            <camunda:outputParameter name="bankdaten">${S(response).childElement("Body").childElement("http://thomas-bayer.com/blz/","getBankResponse").childElement("details")}</camunda:outputParameter>
            <camunda:outputParameter name="bezeichnung">${S(bankdaten).childElement("bezeichnung").textContent()}</camunda:outputParameter>
          </camunda:inputOutput>
          <camunda:connectorId>soap-http-connector</camunda:connectorId>
        </camunda:connector>

I still get the error after adding the dependency.

aravindhrs · January 29, 2020, 6:44am

@Gigli0neiric can you provide camunda server logs? Complete stacktrace?

Gigli0neiric · January 29, 2020, 11:37am

@aravindhrs

It seems like, that the process application is sometimes unavailable. Then Camunda cannot get start form data for process definition. As soon i delete the folder of the snapshot and tomcat rebuild it the error ENGINE-09024 Unable to find resource at path templates/soapEnvelope.ftl occurs.

I’m just a litte bit confused. The project has the same structure of the tutorial:

catalina.2020-01-29.log (60.2 KB)

Hi @Gigli0neiric ,

I am facing similar type of issue. Were you able to solve the issue. Can you help me out in solving the issue. The error is as below:

Cannot instantiate process definition GetHoliday:1:af236818-71d4-11ea-a4bb-621a1d4f98c2: ENGINE-09024 Unable to find resource at path parseHoliday.js

Gigli0neiric · March 29, 2020, 5:27pm

Hi @Kishore,

my problem was, that SPIN wasn’t configured correctly.
I’m using Camunda 7.12 on TomCat, but the Tomcat already has the dependencys for Spin.
So i had to set the scope “provided”. I’m not really shure, why Spin caused the problem…

    <dependency>
		<groupId>org.camunda.spin</groupId>
		<artifactId>camunda-spin-core</artifactId>
	</dependency>

	<dependency>
		<groupId>org.camunda.spin</groupId>
		<artifactId>camunda-spin-dataformat-all</artifactId>
	</dependency>

	<dependency>
		<groupId>org.camunda.bpm</groupId>
		<artifactId>camunda-engine-plugin-spin</artifactId>
	</dependency>

In other cases it depends on, which engine you use to provided your services.

Kishore · March 29, 2020, 5:29pm

Hi @Gigli0neiric,

I am using Camunda Springboot. So on adding the above provided dependencies, will the error get resolved ??

Gigli0neiric · March 29, 2020, 5:35pm

Hi @Kishore,

If you don’t use Spin, dont add it.
I just needed it for the access to my webservice.

Is your GetHolliday file in the deployment folder?

Kishore · March 29, 2020, 5:39pm

Hi @Gigli0neiric,

My GetHoliday file is successfully deployed and is available in the Cockpit. Should i have to deploy parseHoliday.js?

I want to call an External API using http-connector. I configured the connectors and the process model is deployed successfully.
