Problem:
Attempting to use the JYTHON command below and I cannot retrieve the id of my active specification defined at a node-server level in Websphere. I believe its a syntax issue but I'm not sure what.
Code:
AdminConfig.getid('/Cell:mycell/Node:mynode/Server:myserver/J2CActivationSpec:myActiveSpecName/')
Problem Notes:
I do not get a invalid object error so I believe I have the syntax right but it just cannot find the resource even though it exists.
I am using the AdminConfig.getid() as a way to check if the resource already exists in order to do a modify or a create.
If I use the following code: AdminConfig.getid('/J2CActivationSpec:myActiveSpecName/') it will find it but not if I use a more specific path listed above.
Reference Material:
IBM Documentation
Containment paths are always a little tricky. In my (limited) experience, even if you can trace the path by AdminConfig.parents, you may not always be able to use getid.
Are you restricted to using getid? If not, here are some alternatives that will get you an ActivationSpec at the /Cell/Node/Server level:
Querying using AdminConfig.list
This approach will list the Activation Specifications at the specified scope (in our case, the server), and grab the one that has it's name attribute equal to 'myActiveSpecName'.
server = AdminConfig.getid('/Cell:mycell/Node:mynode/Server:myserver')
activationSpec = ''
for as in AdminConfig.list('J2CActivationSpec', server).splitlines():
if AdminConfig.showAttribute(as, 'name') == 'myActiveSpecName'
activationSpec = as
print 'found it :)'
Using Wildcards
This approah uses AdminConfig.list as well, but with a pattern to narrow down your list. If you know your activation spec's configuration begins with myActiveSpecName, then you can do the following:
activationSpec = AdminConfig.list('J2CActivationSpec', 'myActiveSpecName*')

I have a collection of Person, stored in a legacy mongodb server (2.4) and accessed with the mongoid gem via the ruby mongodb driver.
If I perform a
Person.where(email: 'some.existing.email#server.tld').first
I get a result (let's assume I store the id in a variable called "the_very_same_id_obtained_above")
If I perform a
Person.find(the_very_same_id_obtained_above)
I got a
Mongoid::Errors::DocumentNotFound
exception
If I use the javascript syntax to perform the query, the result is found
Person.where("this._id == #{the_very_same_id_obtained_above}").first # this works!
I'm currently trying to migrate the data to a newever version. Currently mongodbrestore-ing on amazon documentdb to make tests (mongodb 3.6 compatible) and the issue remains.
One thing I noticed is that those object ids are peculiar:
5ce24b1169902e72c9739ff6 this works anyway
59de48f53137ec054b000004 this requires the trick
The small number of zeroes toward the end of the id seems to be highly correlated with the problem (I have no idea of the reason).
That's the default:
# Raise an error when performing a #find and the document is not found.
# (default: true)
raise_not_found_error: true
Source: https://docs.mongodb.com/mongoid/current/tutorials/mongoid-configuration/#anatomy-of-a-mongoid-config
If this doesn't answer your question, it's very likely the find method is overridden somewhere in your code!
I just started using the driver org.apache.hive.jdbc.HiveDriver (Version
1.2.1 for spark2) with a Spark Thrift Server (STS) (reference here)
java.sql.ResultSet defines the method absolute() (JavaDoc here)
but HiveBaseResultSet seems to have chosen not to implement the method (source code here)
So now my application (built on top of SmartGWT) was doing a simple operation and I got the following error message:
=== 2017-05-13 18:06:16,980 [3-47] WARN RequestContext - dsRequest.execute() failed:
java.sql.SQLException: Method not supported
at org.apache.hive.jdbc.HiveBaseResultSet.absolute(HiveBaseResultSet.java:70)

at com.isomorphic.sql.SQLDataSource.executeWindowedSelect(SQLDataSource.java:2970)
at com.isomorphic.sql.SQLDataSource.SQLExecute(SQLDataSource.java:2024)
What is the reason that the driver chose not to implement absolute()?
Are there any workaround for the limitation?
Thanks for the hint from Mark Rotteveel. Now I understand better and let me post an answer to my own question.
Implementation of absolute() is optional
As specified by the Interface of ResultSet#absolute() (link), the implementation for absolute() is optional -- especially when the result set type is TYPE_FORWARD_ONLY.
Workaround
In my case, the result set comes from a Spark Thrift Server (STS) so I guess it is indeed forward-only. So the question became how to instruct my application to NOT making a call to absolute(), which is basically for cursor movement.
SmartGWT-specific answer
For SmartGWT, this is controlled by a property called sqlPaging, which we can specified for an OperationBinding. The right value to use seems to be dropAtServer (more reference here). So I set my SmartGWT DataSource XML file to something like this
<operationBindings>
<operationBinding operationType="fetch" progressiveLoading="false"
sqlPaging="dropAtServer"
>
After that I saw another error, which is now related to HiveConnection#commit():
java.sql.SQLException: Method not supported
at org.apache.hive.jdbc.HiveConnection.commit(HiveConnection.java:742)
at org.apache.commons.dbcp.DelegatingConnection.commit(DelegatingConnection.java:334)
at com.isomorphic.sql.SQLTransaction.commitTransaction(SQLTransaction.java:307)
at com.isomorphic.sql.SQLDataSource.commit(SQLDataSource.java:4673)
After more digging, I realized that the right property for SmartGWT to control the commit behavior is autoJoinTransactions and I should set it to false (more reference here). After these two changes, I could get may application to talk to STS via jdbc.HiveDriver
For anyone out there who are also trying this, here is my full settings for the driver in SmartGWT's server.properties (more reference here)

I have this problem and I am not sure why it's happening and how to fix it. I have created an OSB peject. In the proxy service pipeline I am doing a Service Callout to a sync SOAP service in another application. The other service needs the request body as below:
<RequestSelectionValues xmlns="http://www.camstar.com/WebService/WSShopFloor">
<inputServiceData xmlns:q1="http://www.camstar.com/WebService/DataTypes" q1:type="OnlineQuery">
<OnlineQuerySetup>
<__CDOTypeName/>
<__name>xLot By FabLotNumber</__name>
</OnlineQuerySetup>
<Parameters>
<__listItem>
<Name>FabLotNumber</Name>
<DefaultValue>FAB_Lot_1</DefaultValue>
</__listItem>
<__listItem>
<Name>BLOCKOF200ROWS</Name>
<DefaultValue>1</DefaultValue>
</__listItem>
</Parameters>
</inputServiceData>
<queryOption xmlns:q2="http://www.camstar.com/WebService/DataTypes" q2:type="QueryOption">
<RowSetSize>1000</RowSetSize>
<StartRow>1</StartRow>
<QueryType>user</QueryType>
<ChangeCount>0</ChangeCount>
<RequestRecordCount>false</RequestRecordCount>
<RequestRecordSetAndCount>false</RequestRecordSetAndCount>
</queryOption>
<serviceInfo xmlns:q3="http://www.camstar.com/WebService/DataTypes" q3:type="OnlineQuery_Info">
<OnlineQuerySelection>
<RequestValue>false</RequestValue>
<RequestMetadata>false</RequestMetadata>
<RequestSubFieldValues>false</RequestSubFieldValues>
<RequestSelectionValues>true</RequestSelectionValues>
</OnlineQuerySelection>
</serviceInfo>
</RequestSelectionValues>
I am using an Assign to put the above expression in a variable.
Notice the line:
<serviceInfo xmlns:q3="http://www.camstar.com/WebService/DataTypes" q3:type="OnlineQuery_Info">
xmlns:q3="http://www.camstar.com/WebService/DataTypes" needs to be before q3:type="OnlineQuery_Info" for the other service to be called successfully otherwise the service call fails.
In the development it looks fine. I can test the assign of expression as well.
When I go to the OSB console to test the service I notice that in the Assign variable the namespace place switches and it becomes like this:
<serviceInfo q3:type="OnlineQuery_Info" xmlns:q3="http://www.camstar.com/WebService/DataTypes">
This makes the service calls to fail. I have tried putting the body payload in an xslt. Result is the same. I am not sure why it switches the type before namespace. The end result is that the service is not working as expected.
Any idea what I can do to fix this issue. How can I prevent the switching?
Thanks
I haven't found any settings in OSB that can prevent reordering of attributes for you. However, the above OSB behavior is completely XML standard compliant. In fact, the target service side should be XML compliant and treat the two variants mentioned above as the same, because according to XML standard, tow XML documents with only difference in attribute ordering should be treated as the same.
EDIT:
Please go here to download a modified config. My thoughts are:
Specify the business service to invoke in 'Text as Request' mode, as "CamstarLotQuery/business/CSWSShopFloor_Txt" shown below:
Manipulate messages as text, not XML, in your proxy service, as specified in "CamstarLotQuery/proxy/CamstarLotQueryTxt_Txt":
You might need to specify a SOAP Action in http header when calling a business service, depending on the target service.
One solution i can think of is to assign all the namespaces at the Parent Tag Level, and keep the attributes where they are applicable.
Example:
<RequestSelectionValues xmlns:q1="http://www.camstar.com/WebService/DataTypes" xmlns="http://www.camstar.com/WebService/WSShopFloor" xmlns:q2="http://www.camstar.com/WebService/DataTypes" xmlns:q3="http://www.camstar.com/WebService/DataTypes">
But the problem with this implementation is that since the namespace declaration is now Global, you have to declare your namespace prefixes (q1, q2, q3) to the blocks where the namespaces were previously defined.
Example:
<q3:serviceInfo q3:type="OnlineQuery_Info">
<q3:OnlineQuerySelection>
<q3:RequestValue>false</q3:RequestValue>
<q3:RequestMetadata>false</q3:RequestMetadata>
<q3:RequestSubFieldValues>false</q3:RequestSubFieldValues>
<q3:RequestSelectionValues>true</q3:RequestSelectionValues>
</q3:OnlineQuerySelection>
</q3:serviceInfo>
if this namespace prefix is not declared, then as per XML standards, the tag assume the 'default' namespace value - which will be the namespace of the parent.
However, even though this solution has a round-about way of implementation, this solution will definitely work.
In my model, I have several scopes defined such as:
scope :myScope1, where('myField IS NULL')
This works, but I don't need to check for 'Null' - I need to check for '.blank?' - because there are cases of non-nulls which are 'blank' in the DB, which I need to include. I can use '.blank?' in my class-defs (and do - and they work there), but I cannot use this in this current context.
I have not been able to find a syntax (of the non-depreciated variety) which will work for this. Thanks.
Try
scope :myScope1, where("myField IS NULL or CAST(myField as text) = ''")
It's not that simple as blank?, but I can't see a simple enough solution.
I'm developing a magento script to import products from a XML file using the API and a SOAP wsdl connection.
I would like to know the faultcode list, I've been searching it for several days without luck, anyone know if there is one at all and where I can find it?
I need to handle the error codes to avoid the code to stop instead of just skipping the errors and continue importing what is correct.
At the moment I just discovered that the faultcode 101 is "Product not exists.".
Here's how to grab the list for your version of Magento. (I can't imagine this would be radically different between versions, but one never knows what's been done to a system)
Find all your api.xml files.
$ find app/code/core -name 'api.xml'
app/code/core/Mage/Api/etc/api.xml
app/code/core/Mage/Catalog/etc/api.xml
app/code/core/Mage/CatalogInventory/etc/api.xml
app/code/core/Mage/Checkout/etc/api.xml
app/code/core/Mage/Core/etc/api.xml
app/code/core/Mage/Customer/etc/api.xml
app/code/core/Mage/Directory/etc/api.xml
app/code/core/Mage/Downloadable/etc/api.xml
app/code/core/Mage/GiftMessage/etc/api.xml
app/code/core/Mage/Sales/etc/api.xml
app/code/core/Mage/Tag/etc/api.xml
Each file will have one or many <faults/> nodes which will contain the code and message.
<!-- File: app/code/core/Mage/CatalogInventory/etc/api.xml -->
<faults module="cataloginventory">
<not_exists>
<code>101</code>
<message>Product not exists.</message>
</not_exists>
<not_updated>
<code>102</code>
<message>Product inventory not updated. Details in error message.</message>
</not_updated>
</faults>
It's probably worth mentioning that the numeric codes aren't unique. Each "soap object" (unsure what to call these) defines its own.
<!-- File: app/code/core/Mage/Sales/etc/api.xml -->
<faults module="sales">
<not_exists>
<code>100</code>
<message>Requested order not exists.</message>
</not_exists>
<filters_invalid>
<code>101</code>
<message>Invalid filters given. Details in error message.</message>
</filters_invalid>
Good luck!
