Introduction

When TERASOLUNA Server Framework for Java (5.x) is used in JBoss EAP(JBoss Enterprise Application Platform)6 environment, the following settings are required.

  • Creation and setting of jboss-deployment-structure.xml
  • Setting of URI encoding
  • Setting of file upload (Commons FileUpload)

Creation and setting of jboss-deployment-structure.xml

When JBoss's server module conflicts with the library used in TERASOLUNA Server Framework for Java (5.x), the module on JBoss side will take precedence, so it may not work properly.
Therefore, it is necessary to create jboss-deployment-structure.xml and exclude the module on JBoss side (partial reference).
Place jboss-deployment-structure.xml under WEB-INF.

WEB-INF/jboss-deployment-structure.xml

<jboss-deployment-structure>
    <deployment>
        <exclusions>
            <module name="javaee.api" /><!-- (1) -->
            <module name="javax.faces.api" /><!-- (2) -->
            <module name="org.hibernate.validator" /><!-- (3) -->
            <module name="org.jboss.logging" /><!-- (4) -->
            <module name="org.slf4j" /><!-- (5) -->
            <module name="javax.inject.api" /> <!-- (6) -->
        </exclusions>
        <dependencies>
            <module name="javax.annotation.api" /><!-- (7) -->
            <module name="javax.jms.api" /><!-- (8) -->
        </dependencies>
        <exclude-subsystems>
            <subsystem name="jpa" /><!-- (9) -->
        </exclude-subsystems>
    </deployment>
</jboss-deployment-structure>

Sr. No. Explanation
(1)
Since there is a conflict between Bean Validation and JPA version and an error occurs, exclude Java EE module. (This setting is required when using Bean Validation for input check or using JPA as O/R Mapper)
(2)
Since Bean Validation version conflicts and an error occurs, exclude JavaServer Faces module. It should be set as per (1). (This setting is required when using Bean Validation for input check)
(3)
Since Hibernate Validator does not work properly, exclude Hibernate Validator module.
(4)
Since JBoss Logging version conflicts and an error occurs, exclude JBoss Logging module.
(5)
Since application log is not output properly, exclude SLF4J module.
(6)
Since javax.inject.api version conflicts and an error occurs, exclude javax.inject.api module. (In 5.3.0.RELEASE, error does not occur even if it is not excluded)
(7)
Since injection does not work using @Resource annotation, refer javax.annotation.api module.
(8)
Since API class of JMS is required in class path, refer javax.jms.api module. (This setting is required when using JMS) [1]
(9)
Since JPA version conflicts and an error occurs, exclude JPS subsystem from operation. (This setting is required when using JPA as O/R Mapper)
[1]
When specific class of Apache ActiveMQ is used in the application, the added ActiveMQ module should be referred by the method same as "javax.jms.api" module for using the mechanism of resource adapter of JBoss (Refer Resource Adaptersfor the mechanism of resource adapter of JBoss).
There is a method to include jar file of ActiveMQ in war file however, operation verification is not performed by this method.

Setting of URI encoding

In JBoss environment, if multibyte characters are included in the request parameter, garbled characters appear.
In order to avoid this, the following URI encoding setting should be done.
  1. Set default character codes using org.apache.catalina.connector.URI_ENCODING
  2. If character codes are set for each request, apply the same to the request using org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING

Refer the following for how to set.

  1. How to specify default character codes in URI
  2. How to apply character codes of request to the character codes of request parameter in URI

How to specify default character codes in URI

Use org.apache.catalina.connector.URI_ENCODING to set default character codes in URI.

  • Setting example

{JBOSS_HOME}/standalone/configuration/standalone.xml

Add the following settings of <extensions>tag

<!--omitted-->
</extensions>

<system-properties>
    <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>
</system-properties>

"UTF-8" is applied in the above example.

How to apply character codes of request to the character codes of request parameter in URI

When character codes are set to each request using ServletRequest#setCharacterEncoding(String)in application, character codes of request are applied to URI request parameter using org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING.

  • Setting example
request.setCharacterEncoding("Windows-31J");

{JBOSS_HOME}/standalone/configuration/standalone.xml

Add the folloing settings of <extensions>tag

<!--omitted-->
</extensions>

<system-properties>
    <property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/>
    <property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/>
</system-properties>

"Windows-31J" is applied in the above example.

When character codes are not set in request, "UTF-8" specified in org.apache.catalina.connector.URI_ENCODINGis applied.

Setting of file upload (Commons FileUpload)

When file upload function of Servlet 3.0 is used in JBoss, the multibyte characters of request parameter and file name may be garbled.
This problem can be avoided by using Commons FileUpload.
Refer to the explanation of the following guideline for how to use.
