Re: [Epp-rtk-devel] Connecting to INFO And BIZ

[Daniel M. <dm...@li...>]

I would agree with Anthony. Perhaps the URC will help you out.

Another alternative is the design presented in the code sample 
(DynamicProtocolExample.java). I think you might have seen this before 
-- hopefully, Einat passed it to you. it demonstrates how to use the 
0.7.x java RTK to serve multiple registry in the same logical code 
(though, you need separate EPPClient instances/connections for each 
registry). It uses java's introspection to dynamically run RTK code to 
perform EPP operations. Notice that there are no methods called directly 
on RTK classes -- instances of the Method class are used to run the 
show. This sample was built to demonstrate .org and .info running 
together, .biz could easily be added to the HashMap of epp versions. I 
think this design, although very verbose and difficult to read, will 
provide the most gains in terms of reuse of code between handling the 
same EPP commands over different EPP versions.

The only issue which comes to light in this situation, is that the RTK 
properties are "universal" for the RTK. This might cause some headaches 
in coding to make sure, for instance, that the .biz connection uses the 
right certificates to connect to the registry (they use custom certs, 
right?). i.e. you might not want to (or be able to) share the same certs 
between all connections. So you'd have to customize the 
"ssl.props.location" property as you connect to each registry.

The issue at heart here is that you can't use the 0.3.x, 0.4.x, and 
0.5.x Java RTK in the same running application because all of the 
package names are the same (com.tucows.oxrs.epp.rtk.xml...). This was an 
issue raised a while back and Java RTK 0.7.x was released to try to 
solve this issue (after some consultation on this list). It combines all 
of the "popular" releases of EPP into a single jar. The packages from 
the previous releases were renamed in this pattern:
com.tucows.oxrs.epp02.rtk... (.info)
com.tucows.oxrs.epp0402.rtk... (.biz, .us)
com.tucows.oxrs.epp0503.rtk... (.name)
com.tucows.oxrs.epp0604.rtk... (.?)
com.tucows.oxrs.epp0705.rtk... (.org)
and
org.openrtk.idl.epp02...
org.openrtk.idl.epp0402...
org.openrtk.idl.epp0503...
org.openrtk.idl.epp0604...
org.openrtk.idl.epp0705...

Note though, that the short class names were not renamed. So the 
"EPPClient" name is used in all versions of EPP. This means you can't 
readily/easily "import" the package names if you're trying to serve all 
your TLDs through the same logical code (i.e. the same .java file). Like 
if you did something like this:

if ( tld.endsWith(".info") ) {
... do the Domain check command for .info inline
} else if ( tld.endsWith(".biz") ) {
... do the domain check command for .biz inline
} ....

but this might be useful...

if ( tld.endsWith(".info") ) {
InfoTldHandler.doDomainCheck(...);
} else if ( tld.endsWith(".biz") ) {
BizTldHandler.doDomainCheck(...);
} ....

In those handler classes you could use "import" statements to use the 
short RTK class names. Tho, this might result in a lot of duplicated code.

It's all in the design...
