Creating Validation TextArea in DOJO

Creating Validation TextArea in DOJO:

Sometimes we may need to do the validation of the data entered in TextArea but unfortunately the default TextArea provided by DOJO will not support the validation .

We can create a custom component extending both dijit.form.ValidationTextBox and dijit.form.SimpleTextarea, this will provide the functionality of both the ValidationTextBox and
SimpleTextarea.

dojo.declare(
            "ValidationTextarea",
            [dijit.form.ValidationTextBox,dijit.form.SimpleTextarea],
            {
                  postCreate: function() {
                    this.inherited(arguments);
                },
                validate: function() {
                    if (arguments.length==0) {
                    return this.validate(false);
                    }
                    return this.inherited(arguments);
                    },           
                onFocus: function() {
                    if (!this.isValid()) {
                        this.displayMessage(this.getErrorMessage());
                    }
                },
               onBlur: function() {
                    this.validate(false);
                }
             }
        );

We have to add the dojo require for ValidationTextarea  -  dojo.provide("ValidationTextarea");

Using the ValidationTextarea in jsp page:

<textarea id="clntlocn" name="clntlocn" data-dojo-type="ValidationTextarea" required="true" missingMessage="Enter the Client Location Name" rows="2" cols="20"" maxLength="50" style="resize:none"></textarea>

Now we can include all the validations applicable for dijit.form.ValidationTextBox to
ValidationTextarea.

Validating the Email address in DOJO

Validating the Email address in DOJO

<input  data-dojo-type="dijit.form.ValidationTextBox"regExpGen="dojox.validate.regexp.emailAddress" required="true" name="email"  id="email" missingMessage="Enter the Email id"> </input>

We have to add  regExpGen="dojox.validate.regexp.emailAddress" in the
dijit.form.ValidationTextBox

Also, we have to add the following dojo require

dojo.require("dojox.validate.regexp");

Handling the select event of dojo tab container

Handling the select event of dojo tab container:

<div data-dojo-type="dijit/layout/TabContainer" style="height:  400px;" id="client">
   <div id="usersTab" data-dojo-type="dijit/layout/ContentPane" title="Users" >
  
</div>
  <div id="akrTdrTab" data-dojo-type="dijit/layout/ContentPane" title="AKR/TDR" >
   </div>
</div>

Add the below code in the JSP page to handle the selection event of the tab.

<script>
      dojo.addOnLoad(function() {
             tabContainer = dijit.byId('client');
             dojo.connect(tabContainer, "selectChild",handleSelectedTabs);
     });


    function handleSelectedTabs(selectedTab){
           switch(selectedTab.id){
                  case "usersTab":searchUsersData();
                  break;
                  case "akrTdrTab":searchAkrtdrData();
                  break;
       }
}
</script>

java.lang.IllegalArgumentException: Mapped Statements collection does not contain value - iBatis

java.lang.IllegalArgumentException: Mapped Statements collection does not contain value - iBatis

Sometimes we will be receiving the following exception when executing the iBatis queries.

org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.tr.spm.app.persistence.mybatis.clientmgmt.ClientManagmentMapper.getTntGrpid
        at org.apache.ibatis.binding.MapperMethod$SqlCommand.<init>(MapperMethod.java:178)
Caused by: java.lang.IllegalArgumentException: Mapped Statements collection does not contain value for com.tr.spm.app.persistence.mybatis.clientmgmt.ClientManagmentMapper.getTnt
        at org.apache.ibatis.session.Configuration$StrictMap.get(Configuration.java:775)

The issue is due to server could not able to locate the mapper xml file.

Approaches to fix the issue

This might be due to multiple reason, the following are the some of the ways the issue can be fixed.

1. Make sure the mapper xml file is in the same location as the mapper interface

2. Make sure the mapper interface java class name and the mapper xml file is same.

3. When u are using maven make sure the xml files are getting copied when packaging. Make sure we have added the below resource entry under resources section in pom.xml

         <resource>
                <directory>src/main/java</directory>
                <filtering>true</filtering>
                <includes>
                    <include>**/*.xml</include>
                </includes>
          </resource>

Changing the Default Maven Repository Location in Eclipse

Changing the Default Maven Repository Location in Eclipse

Sometimes we may need to change the default repository location of the maven in eclipse, the following steps will help us to do the same.

Steps to change the default repository location of the maven in eclipse

Change the repository path(location of the local repository path) in $MAVEN_HOME\conf\settings.xml file

Change the Settings.xml location in eclipse preferences

Browse the settings.xml file automatically the repository path will be displayed,Click on Apply then Click on Ok.

Setting up the Data Source in TOMCAT with Oracle Universal Connection Pool

Setting up the Data Source in TOMCAT with Oracle Universal Connection Pool :

Download ojdbc6_g.jar and ucp.jar and copy the same to $TOMCAT_HOME/lib folder.

Add the Data Source setup in $TOMCAT_HOME/conf/server.xml as follows under 

<GlobalNamingResources> tag.

  <GlobalNamingResources>

  <Resource
       name="jdbc/SampleConnectionPool"
       auth="Container"
       factory="oracle.ucp.jdbc.PoolDataSourceImpl"
       type="oracle.ucp.jdbc.PoolDataSource"
       description="Pas testing UCP Pool in Tomcat"
       connectionFactoryClassName="oracle.jdbc.pool.OracleDataSource"
       minPoolSize="2"
       maxPoolSize="5"
       inactiveConnectionTimeout="20"
       user="Sample"
       password="Sample"
       url="jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)
            (HOST=localhost)(PORT=1522))(CONNECT_DATA=
            (SERVICE_NAME=SAMPLE)))"
       connectionPoolName="SampleConnectionPool"
       validateConnectionOnBorrow="true"
       sqlForValidateConnection="select 1 from DUAL" />


</GlobalNamingResources>

Change the database details accordingly.

Add Resource Link for the global JNDI resource in $TOMCAT_HOME/conf/context.xml file under <Context>.

<ResourceLink global="jdbc/SampleConnectionPool" name="jdbc/SampleConnectionPool" type="oracle.jdbc.pool.OracleDataSource"/>

Now jdbc/SampleConnectionPool can be used in the code to get the database connection.
