Struts2 Version 2.3.15 HelloWorld Setting

1. Problem:
There are some different after struts2 2.1.3, e.g. the library and the strtus.xml, web.xml setting file


2. Solution:
A. Downlaod form struts-2.3.15.1-lib.zip

B. Use the following Basic library, and copy to WebContent/WEB-INF/lib:
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar
commons-fileupload-1.3.jar
commons-io-2.0.1.jar
commons-lang-2.4.jar
commons-lang3-3.1.jar
commons-logging-1.1.3.jar
freemarker-2.3.19.jar
javassist-3.11.0.GA.jar
ognl-3.0.6.jar
struts2-core-2.3.15.1.jar
xwork-core-2.3.15.1.jar

C. Writing the web.xml, there we use the StrutsPrepareAndExecuteFilter

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    version="2.5">
   
  <filter>
    <filter-name>struts2</filter-name>
    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>struts2</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</web-app>

D. Writing the struts.xml in Project_dir/Java Resource/src and write your action class
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
<constant name="struts.devMode" value="true" />
    <package name="default" extends="struts-default"> 
        <action name="hello" class="ibms.struts2.HelloWorldAction" method="execute">
            <result name="success">/HelloWorld.jsp</result>
        </action>
       
    </package>
</struts>

homozygous and heterozygos

An "allele" does not have zygosity...so it cannot be either hetero- or homozygous. An allele is defined as one of potentially many possibilities at a given location in a genome (a "locus").

A "locus" can be heterozygous or homozygous (among other things), meaning it either has two different alleles, or exactly the same two alleles.

Common SNP terminology is somewhat confusing...based on the acronym one would expect it to refer to a given allele at a specific position, and sometimes it does. However, "SNP" is more often used to refer to a specific base (the "locus") that has multiple possible alleles (for example, a A or a G).

So a heterozygous indel would be one copy of the specific lesion (an insertion or a deletion), the other strand lacking that particular insertion or deletion.

Hopefully that helps, if I didn't understand your question, let me know.

XSLT - eXtensible Stylesheet Language Transformations

1. Description:

Here we demonstrate a simple data.xml, and a showing transformation file of the xslt, then you can using browser to open the data.xml, browser will transform XML into HTML, before it is displayed by a browser.


2.  Code of data.xml
---------------------------------------------------

<?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<?xml-stylesheet type="text/xsl" href="data_xslt_test.xsl"?>
<catalog>
    <cd>
        <title>Empire Burlesque</title>
         <artist>Bob Dylan</artist>
         <country>USA</country>
         <company>Columbia</company>
          <price>10.90</price>
          <year>1985</year>

                    <price>9.90</price>
                    <year>1988</year>
      </cd>

</catalog>

---------------------------------------------------
 Be carefully, this data.xml will refereence the style sheet of href="data_xslt_test.xsl"

 ---------------------------------------------------

file of  xslt of data_xslt_test.xsl

 <?xml version="1.0" encoding="ISO-8859-1"?>
<!-- Edited by XMLSpy® -->
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">

  <body>
  <h2>My CD Collection</h2>
    <table border="1">
      <tr bgcolor="#9acd32">
        <th>Title</th>
        <th>Artist</th>
      </tr>
      <xsl:for-each select="catalog/cd">
      <tr>
        <td><xsl:value-of select="title"/></td>
        <td><xsl:value-of select="artist"/></td>
      </tr>
      </xsl:for-each>
    </table>
  </body>
  </html>
</xsl:template>
