VWPUserFAQsavewebxml

Changes to web.xml are not getting saved, is there a workaround?

1) Try editing web.xml outside of NetBeans first then continue with developing the application and deploying

or


2) The basic idea is re-arranging the web.xml and sun-web.xml files between the build and the deploy steps, taking advantage of the overrideable ANT tasks that VWP makes available. The example below is for adding a reference to a custom datasource.

a) isolate the XML fragment to be added to web.xml, and its final position: 

<resource-ref>
   <description>Database</description>
   <res-ref-name>jdbc/MyDb</res-ref-name>
   <res-type>javax.sql.DataSource</res-type>
   <res-auth>Container</res-auth>
   <res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>

must be inserted in the NetBeans-generated web.xml immediately BEFORE the closing </web-app> tag.

b) isolate the XML fragment to be added to sun-web.xml, and its final position: 

<resource-ref>
   <res-ref-name>jdbc/MyDb</res-ref-name>
   <jndi-name>jdbc/MyDbRef</jndi-name>
</resource-ref>

must be inserted BETWEEN the </context-root> and the <class-loader ...> tags.

c) create a properties file to map string replacement rules. Name the file res-ref.properties and put it in the web/WEB-INF directory of your VWP project:

sunweb=</context-root>\n<resource-ref><res-ref-name>jdbc/LucyStarDb</res-ref-name><jndi-name>jdbc/LucyStarSvil</jndi-name></resource-ref> web=<resource-ref><description>Database</description><res-ref-name>jdbc/LucyStarDb</res-ref-name><res-type>javax.sql.DataSource</res-type><res-auth>Container</res-auth><res-sharing-scope>Shareable</res-sharing-scope></resource-ref>\n</web-app>

d) edit the project's build.xml and add the following ANT code: 

  
    <!-- useful shortcuts for filenames -->
    <property name="prj-web-xml" value="build/web/WEB-INF/web.xml" />
    <property name="prj-sun-web-xml" value="build/web/WEB-INF/sun-web.xml" />
    <property name="prj-res-ref-props" value="build/web/WEB-INF/res-ref.properties" />

    <!-- define a property to be set and true when web configuration files are missing -->
    <condition property="missing-web-files">
        <and>
            <not><available file="${prj-web-xml}"/></not>
            <not><available file="${prj-sun-web-xml}"/></not>
        </and>
    </condition>
   
    <!-- define a property to be set and true when web configuration files are NOT missing -->
    <condition property="avail-web-files">
        <and>
            <available file="${prj-web-xml}" />
            <available file="${prj-sun-web-xml}" />
        </and>
    </condition>
   
    <!-- define a property to be set and true when resource references are missing from configuration files -->
    <condition property="missing-resources">
        <and>
            <available file="${prj-web-xml}" />
            <available file="${prj-sun-web-xml}" />
            <not>
                <isfileselected file="${prj-web-xml}">
                    <contains text="jdbc/MyDb" casesensitive="yes"/>
                </isfileselected>
            </not>
            <not>
                <isfileselected file="${prj-web-xml}">
                    <contains text="jdbc/MyDb" casesensitive="yes"/>
                </isfileselected>
            </not>
        </and>
    </condition>
   
    <!-- define a property to be set and true when resource refs MUST be added to configuration files -->
    <condition property="must-add-res-ref">
        <or>
            <isset property="missing-web-files"/>
            <isset property="missing-resources"/>
        </or>
    </condition>
   
    <!-- override target post-init. This is just for debug, to check action flags ! -->
    <target name="-post-init">
        <echo message="missing files = ${missing-web-files}" />
        <echo message="available files = ${avail-web-files}" />
        <echo message="missing refs = ${missing-resources}" />
        <echo message="so, must add refs = ${must-add-res-ref}" />
    </target>
   
    <!-- override target to re-process configuration files BEFORE creating the distribution .war
         Note that it is performed only if "must-add-res-ref" is set -->
    <target name="-pre-dist" if="must-add-res-ref">
       
        <!-- in web.xml before /web-app -->
        <replace file="${prj-web-xml}"
                 propertyFile="${prj-res-ref-props}">
            <replacefilter
                token="&lt;/web-app&gt;"
                property="web"/>
        </replace>
       
        <!-- in sun-web.xml, between context-root and class-loader -->
        <replace file="${prj-sun-web-xml}"
                 propertyFile="${prj-res-ref-props}">
            <replacefilter
                token="&lt;/context-root&gt;"
                property="sunweb"/>
        </replace>
    </target>
