Jini Installation On RH Linux August 29, 2008

Posted by sandakith in linux, Open Source, Tooling.

I tried to download and run the Installation of Jini on RH Linux and it gave me this error [1]

Which was never accoured to me, when I further lookin to the problem, I found the solution..

We need to have a environment variable LAX_VM set to $JAVA_HOME/jre/bin/java”

BTW this was all with Jini 2.1 with Sun JDK 1.4.x and its Seems like the installer script uses default embedded JVM using LAX_VM argument.

[1]

Extracting the installation resources from the installer archive…
Configuring the installer for this system’s environment…

Launching installer…

Why not.. have a look at WSO2 registry

“WSO2 Registry enables you to store, catalog, index and manage your enterprise meta data in a simple, scalable and easy-to-use model. It is designed around community concepts such as tags, comments, ratings, users and roles.”

WSO2 Registry 1.1 released June 22, 2008

Posted by sandakith in Open Source.
add a comment

The WSO2 Registry team is pleased to announce the release of its
version 1.1.

The WSO2 Registry is a hub for managing data in a web-friendly and
community-enabled way. It was built with enterprise metadata for SOA in
mind, but really it’s up to you – the Registry can hold any kind of
“stuff” including images, service descriptions, text files, office
documents… and every resource you put in the Registry becomes a center
for social activity.

Eschewing the complexity (and WS-* focus) of specs like UDDI, our
Registry uses the Atom Publishing Protocol (via Apache Abdera) to offer
a standard and RESTfully simple remote interface, which can be accessed
easily by custom code, feed readers, and even browsers.

The Registry has been designed both to encourage “grass-roots” community
around your data and also to allow for IT-friendly governance. A full
feature list follows. We hope you’ll find many uses for it, and that
you’ll share them with us as we work to make it even better!

The release can be obtained from: http://wso2.org/downloads/registry

*_Features_*
* Storing and managing arbitrary resources and collections
* Tagging, commenting and rating
* Managing users and roles
* Authentication and authorization on all resources and actions
* Resource / collection versioning and rollback

* Built in media type support for common types (WSDL, XSD)
* Built in support for WSDL and Schema validation
* Built in support for WSI validation
* Dependency management – maintain relationships between dependent
resources
* Pluggable media type handlers for handling custom media types
* Support for processing custom URL patterns via pluggable URL handlers
* Support for custom query languages via pluggable query processors
* Activity log and filtering support for the activity logs
* Atom Publishing Protocol (APP) support for reading/writing the data
store remotely
* Subscribe to directories, comments, tags, etc. with any standard
feed reader (Bloglines, Google Reader, etc)
* Java client for remote access via APP
* Embedded and WAR deployments
* Web based user interface with Web 2.0 look and feel

_*Major changes from last release*_

Known Issues

How to create a signing key from gpg December 19, 2007

Posted by sandakith in linux, Open Source, Tooling.
add a comment

First step

gpg – -gen-key

accept defaults except the keysize(as your level of expectations) and of cause your name and email address

when generating the key if the generator complains that there is not enough CPU work currently being executed to generate enough entropy, generate some events in your OS and do some work (Example : execute a heavy program for example like build a project from source).

Next Step : After the key generation upload the key to a key server, with gpg – -send-keys XXXXXXX

where XXXXXXXX will be the secoend part of your generated key that will be displayed above. Ex XXXXX/XXXXXXXX

Finally the most important next step is to backup the generated key (located in .gnuppg) in a safe and trusted way (You can not loose your private key), this is your decision 🙂

The WSO2 Identity Solution enables LAMP and Java websites to provide strong authentication based on the new interoperable Microsoft CardSpace technology, which is built on the open standards Security Assertion Mark-up Language (SAML) and WS-Trust. WSO2’s new open source security offering features an easy-to-use Identity Provider that is controlled by a simple Web-based management console and supports interoperability with multiple vendors’ CardSpace components, including those provided by Microsoft .NET. The WSO2 Identity Solution also works with enterprises’ current identity directories, such as those based on the Lightweight Directory Access Protocol (LDAP) and Microsoft Active Directory, allowing them to leverage their existing infrastructure. In addition to the Identity Provider WSO2 Identity Solution provides a Relying Party Component Set which plugs into the most common web servers to add support for CardSpace authentication.
