I could not understand the problem. I was concentrating more at the xml expecting some typos or some “xml-combine” issues. I had many unsuccessful attempts to rectify the problem. Finally I wanted to check the java file. I used Eclipse’s new class wizard to create the new class for the pipleline “link” component. In the wizard we can specify the interfaces and super class from which the new class implements and extends respectively. We have to implement two of the methods in order to extend the “PipelineProcessor” interface.
1. getRetCodes()
2. runProcess(Object arg0, PipelineResult arg1)

So by default, Eclipse gave me a default method body for these two methods and my getRetCodes() method looked like the following.

public int[] getRetCodes() {
return null;
}

I changed the method to the following.

public int[] getRetCodes() {
int[] ret = { 1 };
return ret;
}

Surprisingly that solved the issue. I was fuming my eyes and brain on this issue for quite some time. So please make sure that you give proper implementation to the overriding methods.I hope somebody would benefit from this post.

Cheers.

Version: ATG 9.0
Type: Ecommerce
Database: Oracle
App Server: jBoss
IDE : Eclipse
Java version : 1.5

To set up, please modify the build.properties, username.properties and you system environment variables to specify the settings. Please create a new server instance in jboss copying the default folder. Build the application. Once you are done with the build copy the oracle-ds.xml file to deploy folder and oracle jdbc driver to the server lib folder.

Please let me know your thoughts on this. Meanwhile I will continue adding features into it.
Thanks for reading.

Download it here

public void deleteItemFromMap(String[] indexArray){
List beanList = getMap();
MyBean myBean = null;

int index = 0;
int newIndex;

if(indexArray!=null){
for (String indexString : indexArray) {
newIndex = Integer.parseInt(indexString) – index;
myBean = beanList.remove(newIndex);
if(null != myBean){
index = index + 1;
}
}
}

}

This can be used as a stand alone application as well as an eclipse plugin. This works like achieve application in case of of jar files.

Give it a shot.

<init-param>
<param-name>trimSpaces</param-name>
<param-value>true</param-value>
</init-param>

Also we can use the following pattern to reduce white spaces alternatively in dsp pages.

<dspel:page
><dspel:droplet name=”/test”
><dspel:oparam name=”output”
>Name: <dspel:valueof param=”test”
/></dspel:oparam
></dspel:droplet
></dspel:page>

Another approach is to use JSP comments instead of new lines.

<dspel:page><%–
–%><dspel:droplet name=”/test”><%–
–%><dspel:oparam name=”output”><%–
–%>Name: <dspel:valueof param=”test”/><%–
–%></dspel:oparam><%–
–%></dspel:droplet><%–
–%></dspel:page>

NB:- I know the code fragments provided in the topics are very low in readability. Please blame WordPress….

So in an e-Commerce site, we normally have an option to search. Now we search for a term say “ffddjkl” . There is no result associated with that search term. So we display a message indicating that similar to following.

There are no results associated with the term ffddjkl.

Now suppose you have given <EMBED SRC=”http://www.htmlcodetutorial.com/graphics/sounds/1812over.mid” AllowScriptAccess=”always”></EMBED>in the search text field. Obviously there is no results for this term. So we display the the above message, with the new search text. Here comes the vulnerability, when you get the search results page, the midi file gets started to play. So you get the security catch, right?

Here we use the following code segment to display the message.

<fmt:message key=”resourceBundleKey”>
<fmt:param value=”${param.searchText}”/>
</fmt:message>

To avoid the vulnerability, we should have something like this.

<fmt:message key=”resourceBundleKey”>
<fmt:param>
<c:out value=”${param.searchText}” escapeXml=”true”/>
</fmt:param>
</fmt:message>

When you have a tag that doesn’t allow you to set the value by tag body rather than by attribute, use the following.

<c:set var=”myEscapedVar” scope=”page”>
<c:out value=”${param.someRequestParameter}” escapeXml=”true”/>
</c:set>
<some:tag value=”${pageScope.myEscapedVar}”/>

The component which does the encryption is DigestPasswordHasher. We need to override the encryptPassword() method.

The attached is the code fragment used . The copy and paste of the code seems weird. So I am attaching the file.

See it here.

2,. Checkbox
3. Dropdowns
4. Radio buttons
