Hello.
I want to create hierachical expression to access at every level.
An example would says it better :
<?xml version="1.0"?>
<j:jelly xmlns:j="jelly:core" xmlns:s="jelly:myPackage.jelly.SamaTagLibrary">
<s:configuration>
<s:declaration name="declaration">
<s:domain name="referential">
<s:entity name="personne">
<s:attribute name="name"/>
<s:attribute name="forname"/>
<s:entity>
</s:domain>
<s:domain name="ldap">
<s:entity name="person"/>
<s:attribute name="surname"/>
<s:attribute name="givenname"/>
<s:entity>
</s:domain>
</s:declaration>
</s:configuration>
</j:jelly>
After the <declaration> tag I would access to some data
with expression like :
${referential.personne.name}
${referential.personne.forname}
${ldap.person.surname}
but also
${ldap.person} to designate the set of attribute under
//s:[EMAIL PROTECTED]'ldap']/s:[EMAIL PROTECTED]'person']
I have first try this
DomainTag.dotTag ==>
...
HashMap myHashMap = new HashMap();
JellyContext myContext = this.getContext();
myContext.setVariable(getName(), myHashMap);
...
and EntityTag.doTag ==>
...
HashMap domainMap = (HashMap)( this.getContext
().getVariable(((SamaDomainTag)domainTag).getName()) );
if ( domainMap != null )
{
if (domainMap.containsKey(getName()) == true )
{
throw new JellyTagException
("Entity "+getName()+" already exists !");
}
else
{
domainMap.put(getName(),this);
}
}
...
but it's no really pretty.
If I put for each of them
this.getContext().setVariable(getName(), this);
do the Expression evalutation scan from parent to child contexts
to evaluate ${domain.entity.attribute} ?
Can somebody explain "softly" :) the context hierachie between nested elements ?
Thanks a lot :)
PS : setExport(true) implies NullPointerException, and with the first try it
works better without.
There's something I don't understood with JellyContext ?
