How to use Enumerations in JPQL

I have a named query that in the where clause checks for equality like this
ri.status = InstallStatus.COMPLETED
This causes an error:
A parsing problem was encountered resolving the alias - [InstallStatus]
The Catch-22 is, if we send this reference in as a parameter it works as expected.
What am I missing?
Thanks!

Enum constants should be allowed to be used for comparison so you probably hit a bug. Take a look in the glassfish bug tracker and see if someone else has already bumped into this, and if not then just enter a bug.
http://glassfish.dev.java.net/servlets/ProjectIssues
As you mentioned, an input parameter is an alternative.

}I'm not sure what you think you are doing with the set2(elem) call. You are treating a variable as if it were a method.
All you have to do is change set2(elem) to set2.contains(elem) and things would be fine. This is especially weird since you knew that for set1.

How to change Enumerator programmatically in LabVIEW called in Teststand

How to change Enumerator programmatically in LabVIEW called in Teststand ?
I know that Enumerator cannot be changed programmatically since the data type itself different from other controls like Ring and Combo box.
My application involves in Property loader which will load the list of names to Enumerator during Initialization. And the same shall be used by operator to select in further steps for testing. I tried with Ring and combo box but it doesn't works because its not giving dropdown option in TestStand Steps to select the name.
I need a drop down and also programmatically changing the value of the same variable. I had gone through all forum solutions regarding Enum, but I couldn't get any work around for this.
Please suggest me a solution or best work around to do this.
Thanks,
Vijay

Can you provide an example of how a ring control/combo box does not work? This should be the way to do what you want unless I am misunderstanding exactly what you want to do. In theory you could have a dynamic enumerator type, but there are lots of hoops to jump through using VI server and scripting and it is not worth the effort. Aesthetically, you can make the ring control and enumerated data type look exactly the same. I would be using a ring control.
Please post an example of how it does not work.

Can't figure out how to use home sharing

Since the latest couple iTunes updates, my family and I can not figure out how to use home sharing. Everyone in our household has their own iTunes, and for a long time we would just share our music through home sharing. But with the updates, so much has changed that we can no longer figure out how to use it.
I have a lot of purchased albums on another laptop in the house, that im trying to move it all over to my own iTunes, and I have spent a long time searching the internet, and everything. And I just can't figure out how to do it. So.... how does it work now? I would really like to get these albums from my moms iTunes, onto mine. I would hate to have to buy them all over again.
If anyone is able to help me out here, that would be great! Thanks!

The problem im having is that after I am in another library through home sharing, I can't figure out how to select an album and import it to my library. They used to have it set up so that you just highlight all of the songs you want, and then all you had to do was click import. Now I don't even see an import button, or anything else like it. So im lost... I don't know if it's something im doing wrong, or if our home sharing system just isn't working properly.
Thanks for the help.

How to use the same POWL query for multiple users

Hello,
I have defined a POWL query which executes properly. But if I map the same POWL query to 2 portal users and the 2 portal users try to access the same page simultaneously then it gives an error message to one of the users that
"Query 'ABC' is already open in another session."
where 'ABC' is the query name.
Can you please tell me how to use the same POWL query for multiple users ?
A fast reply would be highly appreciated.
Thanks and Regards,

Batch processing usually involves using actions you have recorded. In Action you can insert Path that can be used during processing documents. Path have some size so you may want to only process document that have the same size. Look in the Actions Palette fly-out menu for insert path. It inserts|records the current document work path into the action being worked on and when the action is played it inserts the path into the document as the current work path..

How to use airport time capsule with multiple computers?

I'm sure there are some thread about this but i couldn't find it... so sorry for that but hear me out! =)
I bought the AirPort Time Capsule to back up my MBP
And so i did.
then i thought "let give this one a fresh start" so i erased all of it with the disk utility and re-installed the MBP from the recovery disk.
I dont want all of the stuff i backed up just a few files and some pictures so i brought that back.. so far so good.
Now i want to do a new back up of my MBP so i open time machine settings, pick the drive on the time capsule and then "Choose" i wait for the beck up to begin, and then it fails. It says (sorry for my bad english, im swedish haha) "the mount /Volume/Data-1/StiflersMBP.sparsebundle is already in use for back up.
this is what i want:
i want the "StiflersMBP.sparsebundle" to just be so i can get some stuf when i need them. it's never to be erased.
i want to make a new back up of my MBP as if it's a second computer...
so guys and girls, what is the easiest and best solution?
Best regards!

TM does not work like that.
If you want files to use later.. do not use TM.
Or do not use TM to the same location. Plug a USB drive into the computer and use that as the target for the permanent backup.
Read some details of how TM works so you understand what it will do.

** How to use TO_DATE function in Stored Proc. for JDBC in ABAP-XSL mapping

Hi friends,
I use ABAP-XSL mapping to insert records in Oracle table. My Sender is File and receiver is JDBC. We use Oracle 10g database. All fields in table are VARCHAR2 except one field; this is having type 'DATE'.
I use Stored procedure to update the records in table. I have converted my string into date using the Oracle TO_DATE function. But, when I use this format, it throws an error in the Receiver CC. (But, the message is processed successfully in SXMB_MONI).
The input format I formed like below:
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">
Value in Payload is like below.
<X_EMP_START_DT hasQuot="No" isInput="1" type="DATE">TO_DATE('18-11-1991','DD-MM-YYYY')</X_EMP_START_DT>
Error in CC comes as below:
Error processing request in sax parser: Error when executing statement for table/stored proc. 'SP_EMP_DETAILS' (structure 'STATEMENT'): java.lang.NumberFormatException: For input string: "TO_DATE('18"
Friends, I have tried, but unable to find the correct solution to insert.
Kindly help me to solve this issue.
Kind Regards,
Jegathees P.
(But, the same is working fine if we use direct method in ABAP-XSL ie. not thru Stored Procedure)

Hi Sinha,
Thanks for your reply.
I used the syntax
<xsl:call-template name="date:format-date">
<xsl:with-param name="date-time" select="string" />
<xsl:with-param name="pattern" select="string" />
</xsl:call-template>
in my Abap XSL. But, its not working correctly. The problem is 'href' function to import "date.xsl" in my XSLT is not able to do that. The system throws an error. Moreover, it is not able to write the command 'extension-element-prefixes' in my <xsl:stylesheet namespace>
May be I am not able to understand how to use this.
Anyway, I solved this problem by handling date conversion inside Oracle Stored Procedure. Now, its working fine.
Thank you.

Sender Mail Adapter - S/MIME - How to use it?

Hi guys,
I am trying to figure out how to use the S/MIME security parameter of the Sender Mail Adapter in PI 7.1.
Could anyone point me to some useful documentation/examples/blogs ?
Or perhaps explain what steps are involved when configuring this parameter?
We are pulling emails from an Microsoft Exchange server.
Many thanks,
Aldo

First of all one sender mail adapter has to be tight with a specific sender email address.
The email has to be decrypted as whole, you cannot decrypt parts of it.
Then you store certificates to secure store in J2EE server and point to it in send agreement, this should be equal to HTTPS setup
Check security guide:

How-to use Excel for the XML file input?

Hello all,
Following our discussion with Gerhard Steinhuber on the very nice tutorial from Horst Schaude , "How to upload mass data via XML File Input" , I am starting this new discussion.
In the comments section of this previous cited tutorial, Rufat Gadirov explains how to use a generated XML from Eclipse instead of your XSD file as your source in Excel.
However, in spite of all the instructions, I am still facing the same issue in Excel when I try to save my file as XML : "The XML maps in this workbook are not exportable".
What I try to do is to create one or more Sales Orders with multiple Items in it from a XML File Input, using excel to enter data.
The part with the File input is working (if I directly upload my file to the webDAV, it creates a sales order instance with multiple items).
The only missing part is the Excel data input that I cannot make work. Any help on this matter would be greatly appreciated.
Here is my XML file that I try to use as a source in Excel before inputing data from Excel:

Hello Jacques-Antoine,
I suppose that as you have tried to construct a map from the schema, you have taken the elements from the List level down. In this case I also can't export the map.
But if you take the elements from the level MySalesOrderUploaded down, you'll get the exportable map (screenshots)
