    Camel HL7 component

    John DeStefano Apprentice

      Hi,

       

      Trying to set up the camel hl7 component. I added additional modules to the server module directory for camel mina and camel hl7. The module.xml files look like this:

       

      jboss_server_root/modules/org/apache/camel/hl7/main:

       

      {code:xml}

      <module xmlns="urn:jboss:module:1.0" name="org.apache.camel.hl7">

       

          <resources>

              <resource-root path="camel-hl7-2.9.2.jar"/>

          </resources>

       

          <dependencies>

              <module name="javax.api"/>

              <module name="org.apache.camel.core"/>

              <module name="org.apache.camel.spring"/>

              <module name="org.apache.commons.logging"/>

              <module name="org.springframework"/>

              <module name="org.slf4j"/>

          </dependencies>

      </module>

      {code}

       

      jboss_server_root/modules/org/apache/camel/mina/main:

       

      {code:xml}

      <module xmlns="urn:jboss:module:1.0" name="org.apache.camel.mina">

       

          <resources>

              <resource-root path="camel-mina-2.9.2.jar"/>

          </resources>

       

          <dependencies>

              <module name="javax.api"/>

              <module name="org.apache.camel.core"/>

              <module name="org.apache.camel.spring"/>

              <module name="org.apache.commons.logging"/>

              <module name="org.springframework"/>

              <module name="org.slf4j"/>

          </dependencies>

      </module>

      {code}

       

      I added dependencies to the project manifest.mf as follows:

       

      Dependencies: org.apache.mina, org.apache.camel.mina, org.apache.camel.hl7

       

      The documentation on the Camel site for the hl7 component has a uri that looks like this:

       

      mina:tcp://localhost:8888?sync=true&amp;codec=#hl7codec

       

      For the last parameter, codec, I tried just creating a named bean (in the source attached). Camel uses spring to configure this parameter. Not quite sure what would be analogous in Switchyard.

       

      The switchyard.xml is as follows:

       

      {code:xml}

      <?xml version="1.0" encoding="UTF-8"?>

      <switchyard xmlns="urn:switchyard-config:switchyard:1.0" xmlns:bean="urn:switchyard-component-bean:config:1.0" xmlns:camel="urn:switchyard-component-camel:config:1.0" xmlns:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912" name="test_hl7" targetNamespace="urn:com.example.switchyard:test_hl7:0.0.1-SNAPSHOT">

        <sca:composite name="test_hl7" targetNamespace="urn:com.example.switchyard:test_hl7:0.0.1-SNAPSHOT">

          <sca:service name="MessageReaderService" promote="MessageReaderServiceBean/MessageReaderService">

            <sca:interface.java interface="com.example.switchyard.test_hl7.MessageReaderService"/>

            <camel:binding.camel configURI="mina:tcp://localhost:8888?sync=true&amp;codec=#hl7Codec"/>

          </sca:service>

          <sca:component name="MessageReaderServiceBean">

            <bean:implementation.bean class="com.example.switchyard.test_hl7.MessageReaderServiceBean"/>

            <sca:service name="MessageReaderService">

              <sca:interface.java interface="com.example.switchyard.test_hl7.MessageReaderService"/>

            </sca:service>

          </sca:component>

        </sca:composite>

      </switchyard>

      {code}

       

      When I deploy I get the following exception:

      I've attached the project.

       

      Thanks in advance for any help you can provide.

          Hey John,

           

          I didn't look in any detail, but I think you need to do more work on the module side of things.  I'm pretty sure you need to add your Camel modules to the SwitchYard Camel component module (org/switchyard/component/camel/main/module.xml).  You should be able to figure out what you need to do just by looking at how the other Camel components are configured in there.

           

          Hope that helps you get a bit further.

           

          Best,

          Rob

            Thanks Rob, I'll give that a try.

              Hey John,

              You don't need module for mina - it's present in Switchyard 0.5. For HL7 you need to put import/export definitions.

               

              <module name="org.apache.camel.spring" services="export" export="true">
                <imports>
                  <include path="META-INF/services/org/apache/camel/dataformat"/>
                </imports>
                <exports>
                  <include path="META-INF/services/org/apache/camel/dataformat"/>
                </exports>
              </module>
              

               

              Then you will be able to use HL7 dataformat in camel mediations. To use HL7 classes you don't need these entries. Also check if your JBoss instance contains any startup errors. If modules are wrong or can not be read AS produces

                Hi Guys,

                 

                Thanks for the help. I was able to get much farther. The version of mina that comes with JBoss AS7 is not compatible with the camel HL7 module so I added the required version (1.1.7) in the modules directory. I referenced that one in my hl7 module.xml:

                 

                <module xmlns="urn:jboss:module:1.0" name="org.apache.camel.hl7">

                    <resources>

                        <resource-root path="camel-hl7-2.9.2.jar"/>

                    </resources>

                    <dependencies>

                        <module name="javax.api"/>

                        <module name="org.apache.camel.core"/>

                        <module name="org.apache.camel.spring"/>

                        <module name="org.apache.commons.logging"/>

                        <module name="org.springframework"/>

                        <module name="org.slf4j"/>

                        <module name="org.apache.camel.spring" services="export" export="true">

                            <imports>

                                <include path="META-INF/services/org/apache/camel/dataformat"/>

                            </imports>

                            <exports>

                                <include path="META-INF/services/org/apache/camel/dataformat"/>

                            </exports>

                        </module>

                        <module name="org.apache.mina.mina-core" slot="1.1.7"/>

                        <module name="ca.uhn.hapi"/>

                    </dependencies>

                </module>

                 

                My MANIFEST file now looks like this:

                 

                Dependencies: org.apache.mina:1.1.7, org.apache.camel.mina, org.apache.camel.hl7, ca.uhn.hapi

                 

                Also had to add a module for the require hapi libraries (ca.uhn.hapi).

                 

                <module xmlns="urn:jboss:module:1.0" name="ca.uhn.hapi">

                    <resources>

                        <resource-root path="hapi-base-1.2.jar"/>

                        <resource-root path="hapi-structures-v21-1.2.jar"/>

                        <resource-root path="hapi-structures-v22-1.2.jar"/>

                        <resource-root path="hapi-structures-v23-1.2.jar"/>

                        <resource-root path="hapi-structures-v24-1.2.jar"/>

                        <resource-root path="hapi-structures-v25-1.2.jar"/>

                        <resource-root path="hapi-structures-v26-1.2.jar"/>

                        <resource-root path="hapi-structures-v231-1.2.jar"/>

                        <resource-root path="hapi-structures-v251-1.2.jar"/>

                    </resources>

                    <dependencies>

                        <module name="javax.api"/>

                    </dependencies>

                </module>

                 

                I am now able to send HL7 messages and return an ACK from a method with this signature: public String readMessage(String msg);

                 

                I would like to be able to use the hapi message format with a method signature like "public Message readMessage(Message msg)". The documentation on the camel-hl7 page shows some examples using this type of interchange. When I deploy the switchyard app with the this method signature I get a class not found exception.

                The class ca.uhn.hl7v2.model.Message is contained in one of the jars referenced in the ca.uhn.hapi module (above). This module is also listed in the MANIFEST dependencies. Not sure why this doesn't work?

                 

                Also, when I use the String readMessage(String msg) approach I would expect to see the Camel properties for the HL7 dataformat (in hl7 module.xml under camel spring module) in the switchyard context (listed under message headers on the camel hl7 documentation page). Here is what I get:

                  Hi,

                   

                  I know that you've specified the dependency for 'ca.uhn.hapi' as a manifest header, but from the following stacktrace it does not look like the deployment, test_hl7.jar, contains this dependency:

                  Caused by: java.lang.ClassNotFoundException: ca.uhn.hl7v2.model.Message from [Module "deployment.test_hl7.jar:main" from Service Module Loader]

                   

                  Could you double check the contents of the manifest and post the result:

                   

                   unzip -p test_hl7.jar META-INF/MANIFEST.MF
                  

                   

                  Just thought that for some reason the manifest might have gotten overwritten using building the jar or something like that.

                   

                  Regards,

                   

                  /Daniel

                    Hi,

                     

                    Thanks Daniel for pointing me in the direction I should have looked first. My "custom" manifest appears to be getting overwritten. If I look in the target directory the MANIFEST.MF I created is there and in the correct place (under META-INF). However, when I deploy to the server its getting overwritten. Any ideas how to configure eclipse not to do this. I'm publishing the project to the server in the server view window.

                     

                     

                    Thanks

                      Hi,

                       

                      I added this to my pom file and that worked for not replacing the manifest.mf:

                       

                      <plugin>

                              <artifactId>maven-jar-plugin</artifactId>

                              <version>2.3.1</version>

                              <configuration>

                                <archive>

                                  <manifestFile>src/main/resources/META-INF/MANIFEST.MF</manifestFile>

                                </archive>

                              </configuration>

                              <executions>

                                <execution>

                                  <id>default-jar</id>

                                  <phase>package</phase>

                                  <goals>

                                    <goal>jar</goal>

                                  </goals>

                                </execution>

                              </executions>

                            </plugin>

                       

                       

                      Thanks

                        Hey John,

                         

                        The tooling may be creating META-INF/MANIFEST.MF under src/main/java.  This is a bug.  The fix may be as simple as nuking the spurrious META-INF folder under src/main/java.

                         

                        Best,

                        Rob

                          Hi Rob,

                           

                          Tried what you suggested but it did not work. Went back putting the maven-jar-plugin in the project pom file. I also added the ca.uhn.hapi module to both the Switchayard camel component module and as the only dependency in my MANIFEST.MF. Adding it only to the Switchyard module didn't work. I assume I'm missing some dependencies somewhere. The modular architecture of the app server definitly offers alot of flexibility, but tracking down dependency issues can be somewhat painful. Got working most of what I was looking for. Still haven't been able to use the dataform that Lukasz mentioned above, but I will contine to research this.

                           

                          Thanks for everyones help.
