ClassNotFoundException: cias.system.exception.CodeMaintenanceException

Is that cias.system.exception.CodeMaintenanceException class in the same codeMaintModule.jar, or another jar in same ear ? Or another ear ?

Hi Lyle Wang,

Thank u so much for your replay.

ClassNotFoundException: cias.system.exception.CodeMaintenanceException - This is different JAVA 1.6 Helper Module.

This java helper module, i have generated to jar and added it into EJB codeMaintModule. NO compilation issue

Finally i have generated EAR file and Deployed into JBOSS 6.3. While Deploying am getting those exception.

Notes:

  I could't get deployment issue for Single  EJB module, while deploying , when i add one more EJB module and Generated to EAR file and deployed into JBoss 6.3 EAP.  I am facing Deployment issue in this scenario. please help me.

Hi Lyle Wang,

  As of My understanding , The Common helper jar in "EAP-6.3.0\jboss-eap-6.3\standalone\deployments"  Path are not Recognized at Run-time.

Please help me, where to place my common jar files into JBoss 6.3 EAP to solve that ClassNotFoundException at Run time.  I am Eagerly waiting for your replay

Thanks Advance

Hi Rajiv:

Sorry for late reply.

In terms of common code / component shared by multiple deployments, we usually setup it as custom module in JBoss 7 / EAP 6.x

You need to package these classes / project in a jar and put it under /module folder, then you can declare it as "global module" or use  "jboss-deployment-structure.xml" file to declare dependency.

An example:

Thanks.

Thank you so much for Your Replay.

If you provide me the example. it may very helpful for me to understand more.

Now i have helper jar(I have Created java project and exported into jar)

How to add this generated helper jar under /module folder  and how can i declare that it as "global module. do i need to create any xml file ..if i need to create, how do i need to configure there my helper module. please help

Thanks Advance

[unnijboss]

1. Create a folder JBOSS_HOME/modules/cias/helper/main

2. Create a file called module.xml under the main with the following content

     <module xmlns="urn:jboss:module:1.1" name="cias.helper">

      <resources>

        <resource-root path="helper.jar" />

       </resources>

      <dependencies>

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

       </dependencies>

     </module>

    Add more module dependencies if want.

3. Place your helper.jar under main folder.

4. And at last add a file called "jboss-deployment-structure.xml" inside your ear META-INF with the following content.

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.0">

  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>

  <deployment>

      <dependencies>

          <module name="cias.helper" slot="main" export="true"/>

        </dependencies>

  </deployment>

</jboss-deployment-structure>

5. In case if you want cias.helper as a global module, modify standalone.xml as

<subsystem xmlns="urn:jboss:domain:ee:1.2">

            <global-modules>

                <module name="cias.helper" slot="main"/>

            </global-modules>

            <spec-descriptor-property-replacement>false</spec-descriptor-property-replacement>

            <jboss-descriptor-property-replacement>true</jboss-descriptor-property-replacement>

            <annotation-property-replacement>true</annotation-property-replacement>

</subsystem>

Hi Unni,

Thank you so much .. Your input help me lot

I do have few Clarification in my mind. Can You help on this.

Q1

      I Followed your point still 1-4 as my first option.

The Helper Module is issue has been resolved. after adding the Below line at point 2

<module xmlns="urn:jboss:module:1.1" name="cias.helper">

      <resources>

        <resource-root path="helper.jar" />

       </resources>

      <dependencies>

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

<module name="javax.api" />

       </dependencies>

     </module>

Query : Can you please provide some more input on <dependencies> Tag and <module> Tag. I am not very clear on this, like What are all the packages we need configured in <module> tag. Why do we need to configure, What is the purpose of this.

[lylewang]

That is for the dependencies your module has.

For example, in your module "cias.helper" you use slf4j, but your slf4j classes are not packaged in same helper.jar.

You installed slf4j as another module, now you setup this dependency entry to tell JBoss, my cias.helper module needs slf4j module to work.

So this setup really depends on what your module needs.

Read through the chapter 3 in official document dev. guide, details are included there.
