ESB filters.

We have to send a file from a directory to several servers via FTP. We have created a service with the name of file like filter, with the function GetRequestHeader.
The sentences are:
{ehdr:getRequestHeader('/fhdr:InboundFileHeaderType/fhdr:fileName') = 'payload.xml'};
{ namespace fhdr=http://xmlns.oracle.com/pcbpel/adapter/file/ namespace
ehdr=http://www.oracle.com/XSL/Transform/java/oracle.tip.esb.server.headers.ESBHeaderFunctions }
We have the next questions:
1.-What is wrong in our sentences??
2.-Do we have to configure something else to this???
3.-When we are in the Expression Builder configuration screen of the filter (ehdr:getRequestHeader) the name of the function is not found (ehdr:getRequestHeader), however when we select this function from the funcitons pane the expression is constructed whith "ehdr" prefix. What's wrong with this?
Thank you very much in advance.

Dll do exist as mentioned above. Folder rights are also there, ESB without this feature is working fine.
Dll version mismatch is there which I corrected in file esb.config and same error now showing for version 2.2.0.0.
I have also added dll to resouce of BizTalk application and thus updaed GAC. Restarted host but still same error

Need pointers towards SOAP header based tranformation and filtering in ESB

Hi,
could to help me towards getting sample projects worked on SOAP header based transformation and filtering in ESB
Regards,

Hi.
You can find info ESB home page:
http://www.oracle.com/technology/products/integration/esb/index.html
There you can download esbsamples:

Setting Outbound JMS Headers in ESB

Hi
I've been trying to set the JMSType header in an ESB process, using the following in my XSLT:
<xsl:variable name="JMSType"
select="ehdr:setOutboundHeader('/jhdr:JMSOutboundHeadersAndProperties/jhdr:JMSOutboundHeaders/jhdr:JMSType', 'solihull.cdh.citizen.change', 'jhdr=http://xmlns.oracle.com/pcbpel/adapter/jms/;')"/>
The message gets posted OK, but I have a 2nd ESB process listening specifically for this JMSType, but it does not get fired. If i remove the filter, then it does.
So, I can only assume that the JMSType is not getting set correctly.
Has anyone successfully managed this and does my call above look valid?
Any help appreciated
Chris

Hi,
Your code to set the header is ok, however, filtering is not that simple..
Please use the following code in the Filter expression in Inbound ESB adapter:
{ehdr:getRequestHeader('/jhdr:JMSInboundHeadersAndProperties/jhdr:JMSInboundHeaders/jhdr:JMSType') = 'COMPLETE_ORDER'};{ namespace ehdr=http://www.oracle.com/XSL/Transform/java/oracle.tip.esb.server.headers.ESBHeaderFunctions namespace jhdr=http://xmlns.oracle.com/pcbpel/adapter/jms/ }

Is there a workaround for wsdl with multi-part porttype with ESB?

I am trying to implement a simple connection to a service with ESB, and have been successful in trials with several other products, but when I try to use the SOA adapter with ESB I get the following message.
"The selected porttype is using a message that is invalid for ESB because it is multi-part or has a simple type. The message getTransactionsByRegistrationIdRequest in operation getTransactionsByRegistrationIdRequest of prottype QueryTransactionsWebService is invalid. Please select another porttype of fix the wsdl."
Is there a work around for this?
We would like to use ESB since we are licensed, but continue to have problems.
Any help would be appreciated.

This works out of box in 11 but as a 10.1.3 workaround, You can write a java web service to proxy the multipart service and expose a regular doc literal service wsdl to ESB. This shouldn't be too much work for an experienced java/web service programmer. We are going to enable multipart for a pass through (no filters or xsl) service in 10.1.3.4. Let me know what path you choose.

Help required in ESB

Hi,
I have a requirment where in my ESB is based on two different schemas, one for Request and one for response. Now I have to soap invokations for two diff BPEL Projects. I would be deciding the BPEL process to be invoked based on a parameter in my Request Schema. So when Im trying to create a filter in Router baed on that Parameter in Req, I am getting error, by default the response schema is getting opened, instead of Request shcema.
Can any body please help me in creating the filter based on the Request Parameter.

Hi,
Try posting this message on the SOA Suite discussion forum (SOA Suite
What you are describing, filtering on input XML data (the request SOAP message received by the invoked ESB process) should be possible using the filter option of routing services. Does the SOAP request matches the request message type defined by your request XSD?
Is there more info on the error in the log files?
Regards, Ronald

Exception in ESB Header Functions (ehdr:getRequestHeader)

Hi,
I was working on the context based routing in the ESB.
My scenario is a simple File to File scenario where I want to make some changes
in the Filter Expressions in the Routing service part.
I want to include the Header functions in order to route the file adapters.
If I Input some two text files of different name in Input File what file name I have
specified in the Header must only written in the Output File.
For this I am trying it in RS Filter Expression part and when I drop the Header
function ehdr:getRequestHeader function some exception is shown like
Funtion of name "ehdr:getRequestHeader" not Found .
I was also using the sample Headersupport demo working component which they
have specified in the following link.
http://www.oracle.com/technology/products/integration/esb/files/esb-presentation-headers.pdf
Anyone have Idea on this.

See the samples on the new ESB OTN page. http://www.oracle.com/technology/products/integration/esb/index.html
There isn't much GUI support but look at the JMS sample jdev project and study the filters for routing and xsl for setting headers. The hardest part is setting the namespaces correctly.

ESB Routing Service Byte Order Mark error

Hi,
I have a esb routing service to accept soap messages from an external system. The external system sents messages with a Byte Order Mark for UTF8 at the start. If i look at the tcp messages i see the following:
POST /event/DefaultSystem/CaseVerhuizing/EsbStuf0204Service HTTP/1.1

The three dots signify the hexadecimal value EF BB BF which is for UTF8. This raises an error however in iAS:

It seems the esb routing service is trying to parse the Byte Order Mark as xml and therfore can not find the soap envelope tag? Any help is appreciated!
Kind Regards,

Hi Andre,
We got exactly the same error as you did. Your analysis is also correct; the first 3 bytes of the reply are not interpreted by BPEL/ESB as a BOM, but as 'real' characters.
The problem is due to the fact that the UTF-8 BOM is actually optional in the specifications, and obligatory for UTF-16. The UTF-8 BOM practically has no meaning, and is never used in most SOA applications. However the guys that made the webservice you need to consume are (wrongly) convinced that the UTF-8 BOM is supposed to be there according to the OASIS/W3C specs. Which is not true btw...
For more info on BOMs, check: http://en.wikipedia.org/wiki/Byte_Order_Mark
Unfortunately I don't have the code for our 'proxy' service anymore. I remember that we simply made a little servlet, that uses input- and outputstreams. The inputstream then filters the BOM. Remember to also proxy the WSDL to 'rewrite' the endpoint ;-)
HTH,

Oracle ESB

Hi,
I need small help reg oracle ESB, Actually we are working on oracle ESB we are using Web Services. we are sending requesting through routing service to soap service, then we are getting response from from soap service to routingservice, I need to take the response object and send to 4 different databases. How can we do in oracle ESB, I though we can do that using adapter service, can you guys help me how to that.
Thanks
Vyas

From that response you need to create another routing service. The xsd should be the same as the response of the XSD/WSDL.
In the new routing service you can put filtering on certain fields to choose which database to send it to. If you don't put on a filter the data will be sent to all databases.
have a look at the ESB tutorial. There is a good example there on how to acheive this.

ESB Routing functionality

Hi,
With esb it is easy to create filters to route message based on their content. If two filters match, both targets are invoked.
one question:
Is there any method to implement a if-then-else in this filters? Or even better:
case1, case2, default....

Hi,
Do you mean a scenario like:
if 'condition 1'
then
route to 'output 1'
elsif 'condition 2'
then
route to 'output 2'
etc..Yes you can do this by defining more than 1 filter per routing service. Each filter relates to one of the above conditions. The output items can either be an adapter or another routing service. The same applies to a case construct.
The default construct-filter I guess would be coded as
if not ('condition 1' and 'condition 2' and ...)
then
route to 'output n'
end ifKind regards,
H

What is ESB real value add?

Hi,
While reviewing the new ESB functionality, as I suspected all along, I don't see anything new in ESB. There seems to be lot of overlap with BPEL in terms functionality.
Why can't we use BPEL to do the routing/filtering/transformation provided by ESB? Conceptually ESB Systems and BPEL Processes are analogous to me. I undersand Business Process Orchestration is different from messaging middleware.
My question why can't we orchestrate p2p/pub-sub integration interactions using BPEL? Any ideas/suggestions?
The immediate drawback I see with ESB is you have to deal with lot of dependent artifacts to model a interaction. For example, you need at least one .esb file and .esbsvc for each routing service you have.
Regards,
Rajesh

Agreed, many have been using BPEL for ESB use cases for a while and that is great. I'd say speed, ease of use and enabling a more distributed topology are some good reasons why someone might want to use ESB for stateless data integrations. The console has some additional flexibiliy and enables manage of endpoints and back out changes so that could be another factor. By all means, don't feel compelled to migrate all applicable BPEL processes to ESB, take advantage of ESB when required.
Hope this helps

Done That,
Thanx a ton Dave, it worked.
So I am finally moving on :-)
Just one question Dave, I happened to work on the Beta release of this version too, the problem was not there. How come we have been able to get it in dev preview.

Using NULL and NOT NULL in prompted filters

Dear all,
While trying to grap the concept of prompted filters in sap bo web intelligence, I had a question whether why we cannot use NULL and NOT NULL while creating a prompted filters in our report.

HI,
'Is Null' and 'Not Null' are the predefined functions in webi which only eliminate the null values or considering only null values.
'Is Null' and 'Not Null' are itself predefined functions that why you are not getting prompts.
Null values are standard across the databases so this is defined as a function in webi to specific eliminate the null values.
If something is not standard then there is option in the webi to use different operator with static values or with prompts.
More more information on Null see the Null wiki page.

Interactive report column filters to display differently than column values

Greetings...
We use images a lot in our interactive reports to provide a visual representation to a status, or something locked for update, or what-have-you. By default, when a user clicks the column heading of a column which contains images, the drop-down list that shows up displays the actual images, which is nice for the user to identify exactly which thing they want to filter on. The problem is when the user selects on of the options in the filtering drop-down, the resulting condition that is displayed under the interactive report search bar is the HTML code of the image. I'd like something else to display there because showing the user the HTML code is atrocious.
I didn't think what I want is possible, but then I came across the Page Locks page within ApEx (page 4000:291 in ApEx 4.0.1) which displays a list of all the pages of an application and whether they are locked or not. It also allows you to bulk lock or bulk unlock a bunch of pages. That page uses an interactive report with a column called "Status" which contains images that represent whether the page is locked or not. When you click the "Status" column heading to filter, instead of seeing the images of an open and closed lock, you see the words "Page Locked" and "Page Unlocked." And even better... when you select on of them, the condition that is displayed to the user is very user-friendly.
Can someone tell me how this is done so I can replicate it in my own apps?
Shane.

Why not create the IR using the text you require e.g. 'Lock', 'Unlock' and then use JQuery to replace the text in the report with the image you want. All the filters should then show the plain text and the report will display the image. e.g.
http://apex.oracle.com/pls/apex/f?p=46801:1
Here's what I did:
Firstly make sure the IR has a region template.
Then create a Dynamic Action with the following attributes:
1. Advanced
2. Event: After Refresh
3. Selection Type: Region
4. Region: [select the IR Region]
5. Action: Execute JS Code
6. Fire on page load: [checked]
7. Code:
$('td [headers="TEST"]').each(function(index) {
if ($(this).text() == 'Lock') {
$(this).empty().html('<img src="/i/htmldb/icons/locked_small.gif" alt="Lock" />');
else {
$(this).empty().html('<img src="/i/htmldb/icons/unlocked_small.gif" alt="Unlock" />');
});Where TEST is the column name.
That's it, this may also be of interest:

View Criteria - how to show the VO filtered differently at a time

My requirement is something like this-
I have a detailsVO which is a join of say employee and department table
I need to show the VO in such a way that-
department1
detailsVO <filtered rows for department1)
department2
detailsVO <filtered rows for department2)
department3
detailsVO <filtered rows for department3)
Here each filtered VO is to be show in different UI table
How do I achieve this? Any suggestions? If I use a VOCriteria with :BindDepartment, how do I bind the same detailsVO to show the details?
Please advise.

How about using a tree table?
Or you may want to look at http://tompeez.wordpress.com/2011/12/29/jdeveloper-11-1-2-1-cascading-tables/ which uses two cascading tables.
