Problems in connecting with E1550 mobile BB in Ubuntu 10.04

Sometimes Mobile BB ,say E1550 mount it self but doesn't seems to connect or we even can't see it is there.
So the solution for this problem is...:
Do the following steps after plug in your mobile BB.

1. Create a new rule for udev:

$ sudo vi /etc/udev/rules.d/15-huawei-155x.rules

2. Then type the following:

SUBSYSTEM=="usb",
ATTRS{idProduct}=="1446",
ATTRS{idVendor}=="12d1",
RUN+="/lib/udev/modem-modeswitch --vendor 0x$attr{idVendor} --product 0x$attr{idProduct} --type option-zerocd"

And now go to System>Preference>Network Connections and configure your service provider settings.


And enjoy surfing through the WEB with Lucid Linux

How to setup and test a custom JCR implementation with JCR TCK

JCR TCK stands for Java Content Repository Technology Compatible Kit.

This will guide to test your JCR implementation with JCR2 (JSR 283) TCK.

This example shows how to test WSO2 Governance Registry JCR implementation with JCR TCK.

It is really easy if we can setup a java project (suppose an IDEA project) for testing purposes.

1.Create a new IntellijIDEA project

2.Add the following jars as dependencies to the above created IDEA project.

- jcr-2.0-b114.jar - Download
- jcr-tck-2.0.0.jar - Download
- junit.jar - Download
- org.osgi.core-4.1.0.jar - Download
- jars of your JCR implementation(ex: /.../carbon/components/registry/org.wso2.carbon.registry.jcr/target)

- any other required jars for your impl (for instance in WSO2 greg implementation ,it is better to do an ant inside /..../carbon/products/greg/ modules/distribution/target/wso2greg-3.5.0-SNAPSHOT/bin and add all jars inside /repository/lib and /lib )

3.Then set the following parameters in your test project

- Main Class : junit.swingui.TestRunner

- VM parameters : -Djavax.jcr.tck.properties=/home/subash/aaa/aaa.properties -Dcarbon.home=/home/subash/carbon/core/distribution/target/ wso2carbon-3.0.0-SNAPSHOT.

(Here note that aaa.properties file contains the name (as a value for the key javax.jcr.tck.repository_stub_impl) of your class which extends RepositoryStub ,which is used to return your RepositoryImpl to start the test ,also we have to set the carbon home to the above path ,carbon core)

- Programme parameters : org.apache.jackrabbit.test.api.NodeTest :This is the test class which you are going to test (actually you can change the test class you want , by simply changing this param)
- Working Directory : Set the working dir to your repository product home dir (for instance in this case: /..../carbon/products/greg/modules/distribution/target/wso2greg-3.5.0-SNAPSHOT)

4.Thats it.But remember ,you have to create your own class RepositoryStubImpl (any name which is the value for the key javax.jcr.tck.repository_stub_impl)
and implement getRepository() method such that you return your JCR RepositoryImpl instance.

Problems in installing Moodle

Moodle is an open source project which is basically a Content Management System (CMS).

• You have to download moodle latest version from the moodle website. http://download.moodle.org/. (Remember when you download ,it will have many versions.But always try to use a stable version of it.For instance don't use "moodle-version+" .Because they are updating weekly.Normally for latest versions ,you need to have PHP 4.3.0, MySQL 4.1.16 or Postgres 8.0 or MSSQL 9.0 or Oracle 9.0)

• Install wamp server version 2.0 or later and create a database with the name "moodle" http://docs.moodle.org/en/Installing_Moodle

• Above user guide lines won't enough .Some problems may occur.So you have to explicitly rename the config---.php file in to config.php which is there in your downloaded .zip file and make the following changes in the config.php file.
• Suppose you have installed wamp server(or any compatible server as mentioned above) at C:\wamp\

• $CFG->dbtype = 'mysql'; // mysql or postgres7 (for now)
• $CFG->dbhost = 'localhost'; // eg localhost or db.isp.com
• $CFG->dbname = 'moodle'; // database name, eg moodle
• $CFG->dbuser = 'root'; // your database username
• $CFG->dbpass = ''; // your database password
• $CFG->prefix = 'mdl_';

• $CFG->wwwroot = 'http://localhost/moodle' //your root folder
• $CFG->dirroot = 'C:\wamp\www\moodle' // your working directory (if you really work with )
• $CFG->dataroot = 'E:\wamp\www\moodledata' // directory where moodle keeps your custom data


Then go to local host from your browser and you only have to do some clicks of next,next,next...And enjoy moodle. A pretty useful CMS.
