Suppressing the Selection Failure exception in Assign activity – Oracle SOA Suite

This post will explain how to suppress the Selection Failure exception BPEL Assign activity – Oracle SOA Suite
In BPEL Assign activity if the xpath returns empty result then SelectionFailure RuntimeFault will be thrown by the engine.

But some cases we may need to suppress the selectionFailure error while assigning the optional elements.

In my case I have a assign activity that will mapthe elements  input and input1 from inputVariable to result and result1 of outputVariable.

Don't support MessageVariable in fromPart -  Oracle SOA Suite:

This error will be thrown while invoking the service with Multipart Message type and the receive activity uses the fromPart to retrieve the parts data and assign to a variables created based on message type or invoke activity uses toPart to assign the data to parts based message type variable.


To resolve this whenever retrieving or assigning values to parts in receive/invoke activity through fromPart or toPart use the element based variables instead using the message type based variable.

window.location.href is not working while clicking on hyper link  in IE

I was trying to redirect to a page while clicking on a hyper link with JQuery Ajax and java script windows.location.href

<a id="signout" href="">signOut<a/>

<script>
    $("#signout").click(function(){

                       $.ajax({
                        type : "POST",
                        async: false,
                        url : "/services/logout",                    
                        success : function() {
                                       window.location="/content/test/test.html";
 },
error : function() {
                                       window.location="/content/test/test.html";
}
});
    } );
</script>

This is working perfectly in both Firefox and Chrome but it is not working in IE.

In IE while redirecting the URL is stripped off to /content/test/(test.html got removed while performing the redirect)

The issue can be fixed as below by adding # in href attribute.

<a id="signout" href="#">signOut<a/>

Removing the Cookie is not working in IE10 and IE11

While trying to remove the cookies in IE10 and IE11 through Java, the cookies are not getting removed in the browser.

The code snippet used to remove the cookie:

Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (int i = 0; i < cookies.length; i++) {
String cookieName = "SampleCookieName";
Cookie cookie = cookies[i];
if (cookieName.equals(cookie.getName())) {
cookie.setPath("/");
cookie.setMaxAge(0);
response.addCookie(cookie);
}
}
}

The root cause of  the issue is IE10 and IE11 expecting the value for the attribute Expires as 0 not for Max-Age.

Fix for the issue - Use the below code to remove the cookies

Cookie[] cookies = request.getCookies();
if (cookies != null) {
for (int i = 0; i < cookies.length; i++) {
String cookieName = "SampleCookie";
Cookie cookie = cookies[i];
if (cookieName.equals(cookie.getName())) {
StringBuilder cookieString = new StringBuilder(cookieHeaderName + "=" + "" + "; ");

cookieString.append("Expires=0" + "; ");
cookieString.append("Version=0; ");
cookieString.append("Path=/; ");
cookieString.append("Max-Age=0" + "; ");
//cookieString.append("HttpOnly");

response.addHeader("Set-Cookie", cookieString.toString());
}
}
}

Enabling Multi Site supports in Adobe Experience Manager(AEM) through Dispatcher and publisher configurations

We are using the image renditions to display the images for different devices in Adobe Experience Manager(AEM).

The HTML5 Adaptive image is used as shown below to display the images for different devices.

<img src="/content/dam/Albin/Untitled.jpg" srcset="/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png 1x,/content/dam/Albin/Untitled.jpg" alt="Sample Image">

/content/dam/Albin/Untitled.jpg - Original image
/content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png - Rendition for 1x devices.

If the image is first accessed from the mobile devices then Untitled.jpg folder is created to cache the renditions image(rendition images will be matched for mobile devices) - /content/dam/Albin/Untitled.jpg/jcr:content/renditions/cq5dam.thumbnail.319.319.png

While the image is getting accessed from desktop browsers then dispatcher will try to return the folder Untitled.jpg as image(/content/dam/Albin/Untitled.jpg - original image will be matched for desktop browsers) so the image link will be broken in browser.

In other hand, if the image is first accessed from desktop browser then dispatcher caches Untitled.jpg as image. The subsequent request to the renditions image will not find the images in dispatcher cache so the image will be retrieved from publisher for rendering(rendition images will not be cached in this scenario as untitled.jpg is created as a image).
