The key to success for a web site is good search engine ranking. All of the major search engines use link popularity to determine how well a site will rank - so the more high quality, relevant links that lead to your site, the higher it will rank. LinkMachine makes it easy to get the links you need by helping you establish hundreds of quality, relevant link exchanges.
LinkMachine will help you:
- Climb to the top of the search engines
- Gain quality links to your site today
- Automate your link management
- Uncover exactly how to beat your top competitors
- Attract thousands more targeted visitors to your site
The most effective way to interest webmasters in linking to your site is by offering to exchange reciprocal links. This is a win-win situation - both of your web sites benefit from new targeted, relevant links.
LinkMachine project helps you build as large a reciprocal link program as youd like. Search engines see all of the new links pointing from other quality, relevant sites to your site, and increase your rank. Note that this is very different from using indiscriminate "link farms", which will give you no advantage with the search engines.
Google recently revealed the secrets of its search ranking technology by filing a patent application. What we found out is that Google values organic link building - link building that progresses naturally rather than appearing artificial. LinkMachine is the ideal tool for building link exchanges the way Google likes them.
LinkMachines InstantLinks system and link search tools allow you to grow your link exchanges gradually and gain links from many different sites. And with LinkMachines Alternate Profiles feature, you can easily benefit from having the links to your site use a diverse variety of anchor text.

fetchExc project is java utilily which retrieves mail from your MS Exchange (2000/2003) inbox and forwards it to SMTP server of your choice or mbox type file.
FetchExc uses webDAV (OWA) to retrieve mail either over http or https. This is also means that you administrator must have left Outlook Webaccess available in Exchange in order to get this utility to work.
Although version number is still below 1.0 I consider this program usable in production environment.
There are still many places that should be polished and improved but atleast there havent been major problems in over an half a year. Before you install read installation instructions from below carefully.
Installing:
So far this only covers *nix systems (windows instructions may follow if they are needed)
Extract fetchExc-*.tar.gz or make directory for fetchExc.jar. If you are downloading Jakarta components yourself put them in the same directory as fetchExc.jar.
Create fetchExc.properties file in your home directory. Remember to protect it with chmod 700 (it contains your password). If you took .tar.gz package there should be example included.
ExchangeServer=xxx.dddddd.com
ExchangePath=exchange
ExchangeUser=exuser
MailServer=yyy.dddddd.com
DestinationAddress=user@yyy.dddddd.com
Username=domainuser
Password=domainpassword
Domain=DOMAIN
Delete=false
All=false
Secure=true
FBApath=/exchweb/bin/auth/owaauth.dll
ExchangeServer - Name of your MS Exchange server.
ExchangePath - Exchange path for MS Exchange OutLook WebAccess.
ExchangeUser - Name of you MS Exchange User.
You can test first three properties by making URL out of them: http://xxx.dddddd.com/exchange/exuser. This should give you a Outlook Webaccess Page.
MboxFile - Path and name of mbox-type mail box. This disables MailServer- and DestinationAddress-properties. Be careful with this because Im not 100% sure that file locking works (YMMV). If there are problems let me know. Also success reports would be nice.
MailServer - Name of your SMTP Server which receives forwarded messages. If there is MboxFile defined this property wont be used.
DestinationAddess - Address of recipient of forwarded messages. If there is MboxFile defined this property wont be used.
Username - Username for your windows domain user. It may be same as ExchangeUser but necessarily.
Password - Password for domain user.
Domain - Domain for above user.
Delete - Whether program should delete mail from Inbox or just mark them as read. If Delete is true mail will be deleted after succesful forwarding. Any other value will just mark message as read. While you are configuring other properties I strongly recommend that you use value false for this property.
All - Whether program should real all mail from Inbox or just which are not read yet. If All is true every mail will be read. Any other value will read only unread mail. While you are configuring other properties I strongly recommend that you use value false for this property.
WARNING!!! Dont combine Delete=false and All=true if you are not testing. That will fetch every mail from your Inbox everytime you start the program.
Secure - If value is true program will use https. Any other value will use http. Https should be user whenever possible.
FBApath - Path to form based authentication. If not set defaults to /exchweb/bin/auth/owaauth.dll. This can be found on FBA login page source (hint: search for "destination")
ForceFrom - If this is set to true forwarded mail will be forwarded with address from ForceFromAddr parameter. This only happens when sender address is not valid. For example if there is two From: fields in mail header Exchange can join addresses. NOTE: This may help spam to get through so use carefully.
ForceFromAddr - E-mail address that forwarding server will accept. Only used if ForceFrom is true
NoEightBitMime - If this is true SMTP forwarding doesnt use BODY=8BITMIME. Default is false.
Now you just need to include JRE in you path. If it is in you path you can run program:
java -jar /install/fetchExc/fetchExc.jar
You can now (>0.80) use -p switch to change properties file. For example:
java -jar /install/fetchExc/fetchExc.jar -p test.properties
would run program using properties from test.properties
I use fetchExc with following little shell script and crontab entry so that it keeps fetching mail every two minutes.
fetchExc
#!/bin/bash
export PATH=$PATH:/usr/local/jre/bin
java -jar /install/fetchExc/fetchExc.jar $* >> fetchExc.log 2>> fetchExc.err
If you use this script replace /usr/local/jre/bin with path to your java runtime environment. Same applies to location of your installation on next line.
crontab entry:
*/2 * * * * ~jrauti/bin/fetchExc
Enhancements:
- Java has been changed from 1.4 to 1.5.
- The Jakarta HHTTP client has been upgraded from 2.0 to 3.0.
- Proxying also works with HTTPS.
- Code cleanups.
- A small fix in mbox saving (in Mac OS X, messages were coalesced).

Skaringa is an API for Java and XML language binding.
It transforms Java objects into XML documents and back, and can generate XML schema definitions for a Java class.
Typical applications are data exchange, object persistence, object transformation, and driving XML based presentation layers.
Skaringa is designed for speed and simplicity, supporting a wide range of types. Skaringa works with all Plain Old Java Objects (POJOs), it is not limited to special cases, like JavaBeans.
Enhancements:
- New layout of documentation and website.
- Use SiteBuilder to generate HTML documententation.

DBIx::XMLMessage is a Perl module for XML Message exchange between DBI data sources.

The package maintains simple XML templates that describe object structure.

The package is capable of generating SQL statements based on these templates and executing them against DBI data sources. After executing the SQL, the package formats the data results into XML strings. E.g. the following simple template

< TEMPLATE NAME=SysLogins TYPE=XML VERSION=1.0 TABLE=syslogins
ACTION=SAVE >
< KEY NAME=suid DATATYPE=NUMERIC PARENT_NAME=OBJECT_ID / >
< COLUMN NAME=LoginId EXPR=suid DATATYPE=NUMERIC / >
< /TEMPLATE >

being executed with key value = 1, will be tranlated into this SQL:

SELECT suid LoginId FROM syslogins where suid = 1

and the result will be formatted into this XML string:

< SysLogins >
< LoginId >1< LoginId >
< /SysLogins >

Inbound messages can be processed according to the same kind of templates and the database is updated accordingly. Templates are capable of defining the SQL operators, plus new SAVE operation which is basically a combination of SELECT and either INSERT or UPDATE depending on whether the record was found by the compound key value or not.
