Muse databases and customer uploads

A 'tricky' website challenge
Firstly, many thanks to Adobe for the great CC Trial.
As a starter in building websites I am running Adobe Muse CC Trial and I am considering using it (and perhaps other programmes in the subscription CC package) to create an e-commerce site. I'm very impressed with the Muse functionality, especially for a beginner like me but there are numerous questions that I need answers to...and I can't find any Adobe documents that answer them. Can anyone help please?
At this stage I don't want to get into fine-grained detail on a complete specification so I hope the folowing suffices to give a reasonable idea.
AIM
The website is to provide visitors/customers with a "customer space" to upload, store and view photos, videos together with their descriptions. All to be made either private by the use of individual customer passwords or publicly viewable without any special permissions needed.
As additional features each of the above "customer space" of the site must be:
indexed so that it can be searched and found via unique indexed fields such as name address, date and others (to be decided)
visitors can search for, locate and view the "customer space" and then add their comments in what would be a "visitor or guest book"
My purposes in this short enquiry are are to:
find out if the basic concept is do-able - all within Adobe Muse
find out if Adobe's hosting will accommodate the site given that data storage and transactions, online queries/traffic etc. might eventually be substantial...but obviously zero to start with
discover what database Adobe uses in its servers as part of its hosting service e.g.mySQL or other
how to secure the site so that 'customer uploads' can filter out malware and only allow uploads from bona fide customers
identify what other software packages I would need to build the above i.e. database and/or other programmes
establish Adobe's standard and/or other hosting Service Levels and associated business agreements
If anyone can point me in the right direction regarding the above and any other relevant advice I'd greatly appreciate it.
Mike
p.s. As a constructive comment: I find it strange that while Adobe is promoting its excellent products, it seems to rely on a forum to answer questions such as those I have asked above.But then, maybe Adobe has published relevant docs online and I just haven't been able to find them.

Moved from Cloud forum to Muse forum to get input from Muse users.

How to retrieve data using logical database and custom select options

Hi all,
I have a selection screen which is displayed by logical database PSJ and I have two select options of my own. I need to retrieve data based on both selection screen of logical database and my own select options. How can I do it?
Thanks in advance.

Hai Gupta
Check the following Document & Links
1. A logical database is in fact
a program only.
2. This LDB provides two main things :
a) a pre-defined selection screen
which handles all user inputs and validations
b) pre defined set of data
based upon the user selection.
3. So we dont have to worry about from
which tables to fetch data.
4. Moreover, this LDB Program,
handles all user-authorisations
and is efficient in all respects.
5. tcode is SLDB
good info about Logical Database. you can check the link.

Re: Logical databases
http://help.sap.com/saphelp_46c/helpdata/en/9f/db9bed35c111d1829f0000e829fbfe/frameset.htm
Functions for displaying and changing logical databases:
Call Transaction SE36 or
Choose ABAP Workbench -> Development -> Programming environ. -> Logical databases
Interaction between database program and report:
During program processing, subroutines are performed in the database program and events are executed in the report.
To read data from a database tables we use logical database.
A logical database provides read-only access to a group of related tables to an ABAP/4 program.
advantages:-
The programmer need not worry about the primary key for each table.Because Logical database knows how the different tables relate to each other,and can issue the SELECT command with proper where clause to retrieve the data.
i)An easy-to-use standard user interface.
ii)check functions which check that user input is complete,correct,and plausible.
iii)meaningful data selection.
iv)central authorization checks for database accesses.
v)good read access performance while retaining the hierarchical data view determined by the application logic.
disadvantages:-
i)If you donot specify a logical database in the program attributes,the GET events never occur.
ii)There is no ENDGET command,so the code block associated with an event ends with the next event
statement (such as another GET or an END-OF-SELECTION).
1. transaction code SLDB.
2.enter name z<ldb-name>
3.create
4.short text
5.create
6. name of root node (here Ekko)
7. enter short text (f6)
8.node type -> data base table.
9.create
10 change logical DB
riht click on ekko and insert node
here node name ekpo
11.create
12. click on selections
13. press no Should the changed structure of Z<ldb name> be saved first.
14.select tables which you want to join.
15.transfer
16 now you have to o to coding part.
17. save
activate.
19.click to src code
double click on first include and activate

Problem using secondary database, sequence (and custom tuple binding)

I get an exception when I try to open a Sequence to a database that has a custom tuple binding and a secondary database. I have a guess what the issue is (below), but it boils down to my custom tuple-binding being invoked when opening the sequence. Here is the exception:
java.lang.IndexOutOfBoundsException

Here is my code:
// URL ID DB
DatabaseConfig urlDBConfig = new DatabaseConfig();
urlDBConfig.setAllowCreate(true);
urlDBConfig.setReadOnly(false);
urlDBConfig.setTransactional(true);
urlDBConfig.setSortedDuplicates(false); // No sorted duplicates (can't have them with a secondary DB)
mURLDatabase = mDBEnv.openDatabase(txn, "URLDatabase", urlDBConfig);
// Reverse URL lookup DB table
SecondaryConfig secondaryURLDBConfig = new SecondaryConfig();
secondaryURLDBConfig.setAllowCreate(true);
secondaryURLDBConfig.setReadOnly(false);
secondaryURLDBConfig.setTransactional(true);
TupleBinding urlTupleBinding = DataHelper.instance().createURLTupleBinding();
SecondaryURLKeyCreator secondaryURLKeyCreator = new SecondaryURLKeyCreator(urlTupleBinding);
secondaryURLDBConfig.setKeyCreator(secondaryURLKeyCreator);
mReverseLookpupURLDatabase = mDBEnv.openSecondaryDatabase(txn, "SecondaryURLDatabase", mURLDatabase, secondaryURLDBConfig);
// Open the URL ID sequence
SequenceConfig urlIDSequenceConfig = new SequenceConfig();
urlIDSequenceConfig.setAllowCreate(true);
urlIDSequenceConfig.setInitialValue(1);
mURLSequence = mURLDatabase.openSequence(txn, new DatabaseEntry(URLID_SEQUENCE_NAME.getBytes("UTF-8")), urlIDSequenceConfig);
My secondary key creator class looks like this:
public class SecondaryURLKeyCreator implements SecondaryKeyCreator {
// Member variables
private TupleBinding mTupleBinding; // The tuple binding
* Constructor.
public SecondaryURLKeyCreator(TupleBinding iTupleBinding) {
mTupleBinding = iTupleBinding;
* Create the secondary key.
public boolean createSecondaryKey(SecondaryDatabase iSecDB, DatabaseEntry iKeyEntry, DatabaseEntry iDataEntry, DatabaseEntry oResultEntry) {
try {
URLData urlData = (URLData)mTupleBinding.entryToObject(iDataEntry);
String URL = urlData.getURL();
oResultEntry.setData(URL.getBytes("UTF-8"));
catch (IOException willNeverOccur) {
// Success
return(true);
I think I understand what is going on, and I only noticed it now because I added more fields to my custom data (and tuple binding):
com.sleepycat.je.Sequence.java line 139 (version 3.2.44) does this:
status = cursor.putNoOverwrite(key, makeData());
makeData creates a byte array of size MAX_DATA_SIZE (50 bytes) -- which has nothing to do with my custom data.
The trigger causes an call to SecondaryDatable.updateSecondary(...) to the secondary DB.
updateSecondary calls createSecondaryKey in my SecondaryKeyCreator, which calls entityToObject() in my tuple-binding, which calls TupleInput.readString(), etc to match my custom data. Since what is being read goes for more than the byte array of size 50, I get the exception.
I didn't notice before because my custom tuple binding used to read fewer that 50 bytes.
I think the problem is that my tuple binding is being invoked at all at this point -- opening a sequence -- since there is no data on which it can act.

Hi,
It looks like you're making a common mistake with sequences which is to store the sequence itself in a database that is also used for application data. The sequence should normally be stored in separate database to prevent configuration conflicts and actual data conflicts between the sequence record and the application records.
I suggest that you create another database whose only purpose is to hold the sequence record. This database will contain only a single record -- the sequence. If you have more than one sequence, storing all sequences in the same database makes sense and is safe.
The database used for storing sequences should not normally have any associated secondary databases and should not be configured for duplicates.

Database and ejb access in Input Processor, custom Validator

Hi guys,
I know the Portal docs recommend that database and ejb calls should be done in
a Pipeline Component. Are transactions the only concern?
I'd like to validate two fields. This can be easily accomplished by a an ejb
method call that returns a boolean for one, and by running a simple select statement
for the other. Are there any risks to creating custom validator classes to do
this?
Thanks

David,
Here are the characterstics of Pipelines and IPs:
Inputprocessors:
- Web App scope (classloaded by webapp classloader)
- simple java class
Pipelines/Pipeline Components:
- Enterprise App scope (available to all webapps)
- java class or EJB
- can be transactional (can even rollback PipelineSession)
- Pipelines executed from within the EJB container
There is nothing illegal about putting EJB calls and JDBC calls into an Inputprocessor.
For simple validation, this is probably okay. However, when doing heavy business
logic, having the Pipeline manage a single transaction for your PCs is wonderful.

The latest changes to the function to "Upload to FTP host" has rendered this useless - no point using a program like Muse if I can not easily and automatically upload the work to the webserver!

The latest changes to the function to "Upload to FTP Host" has rendered this useless - no point using a program like Muse if I can not easily and automatically upload the work to the webserver! I use BlueHost webhosting that has a primary domain and I have several domains with that account (as sub-domains or folders on this server) - with past versions of Muse when uploading pages it simply opened an alert window to tell me (what I already know) that the website I was uploading does not point to the primary domain BUT NOW Muse tries to create a new separate folder in the root directory of the primary domain - completely ignoring the directory path I am giving it - useless! Why make these senseless changes to the program - and so often - very frustrating it is like amateur ware!.

Hi Stephen,
There are some issues with the upload to ftp via Muse, which the engineering team is aware of and those will be fixed in a future build of Muse. At this point the work around would be to export the html from Muse and then upload via some third party ftp client like filezilla.
I will recommend that you keep an eye on our release notes page to get more updates on it - Release notes | Adobe Muse CC

Customer upload photos and descriptions classifieds

Customer upload file app.
When a person submits photos with descriptions in the app i create for Business Catlyst, the descriptions all blend together with commas in a paragraph when I receive the informaation form the server. This make it hard to see what descriptions goes with which photos. How can make this information come in differently?

Ok-- I'm signed up but when I login it says that my secure zone access is denied. In the email I received it says I currently have access to "Member Only Area (Expires 31-Dec-9999)
Do you have a default home page setup for that secure zone? There's no way to get to the web app submission form from the main navigation so maybe you can get me the URL to that page which I might be able to reach if I'm logged in.

Logical Database and Logical Thing

Hi,
i want to access KONV which is cluster table and the field is KWERT.
The thing is that i want to access it by taking customers from KNVV and giving it to VBRK (SALES Table). Now in VBRK i want to have a selection on FKDAT to get a list of Customers stored in the field called KUNAG.
on VBRK-KUNAG basis i want to access the table KONV-KWERT.
If i am doing queries then the System stops responding cuz it has got alot of overhead. So i tried to use Logical Database called VFV.
If this is the best solution means using LDB then how to use it, can anyone help me with this. I tried it by Function module but it is showing all data without considering selection criteria.
If anyone can help me then plz do answer or refer me to any web site so that i can figure this thing out. If anyione has got a good book on that then plz feel free to mail me.

Thanks Shibba that was very helpful, i applied that but the system overhead was so much.
can u help me with Dynamic selection code.
I used FREE_SELECTION_INIT, FREE_SELECTION_DIALOG and then FREE_SELECTIONS_RANGE_2_WHERE to get ther Selections in one table.
if u want me to send u the code then i can do that cuz i am getting so much mad that this work is not done yet.
The Scenario here is that we want to take BILLED Customers and VKORG as Industrial Billing Customer and then taking VBRK and giving all these Customers and then taking selection on FKDAT range.
Now after that the data should be collected from KONV-KWERT and i want to perform some calculation over it. I am using VFV (Logical Database) to perform this thing because i know that it would be very fast then applying my own queries.
If you can mail me any book on Logical Database and Dynamic selection then it will be very Helpful.
Thanks once again for being such helpful.

Catch datetime exception and custom error message in SSRS

I currently working on create report by using SSRS. I have 2 parameters: [Start date] and [End date] to filter data from database and show it on report. I want to validate 2 datetime parameter as describe above. Please tell me a solution to do this.
For example:
When user type the text like: 4/15/2014mmm => System validation thrown a message: [The From Date not correct type]
But in my case, I want to receive a custom error message by myself.(Look like: [Date Invalid!])

Hi Brain,
According to your description, you have a report with two parameters for user to input. Now you want to validate these two parameters and display custom error message when the date is invalid. Right?
In Reporting Service, it doesn’t provide any interference for us to modify the system error message (the text in grey color). That means we can’t modify the system message when error occurs. However we can create a textbox in this report, use custom code
and expression to display the custom error message. But this all based on the report is successfully running. So if error occurs during report processing, all the custom code and expression will not work. In this scenario, we find a workaround for you. We
use custom code to judge if the date is valid, if the users type an invalid date, we return a default value to make sure this report can successfully run. Then we use expression to control the visibility of tablix in this report and create a textbox to show
the custom error message. Your case has been tested in our local environment. Here are steps and screenshots for your reference:
Go to Report Properties. Put the code below into custom code:
Public Shared a As Integer=0
Public Shared Function IsDate(d1 As String,d2 As String) as Integer
        Try
           FormatDateTime(d1)
           FormatDateTime(d2)
        Catch ex As Exception
                   a=1
        End Try
return a
End Function
Create two parameters. One is StartDate, the other is EndDate. Set the data type of these two parameters Text.
Create a filter for StartDate, put the expression below into Value:
=IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,CDate(IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,Parameters!StartDate.Value,"1/1/2012")),CDate("1/1/2012"))
Create a filter for EndDate, put the expression below into Value:
=IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,CDate(IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,Parameters!EndDate.Value,"1/1/2013")),CDate("1/1/2013"))
Ps: In step3 and step4, the date(“1/1/2012”, “1/1/2013”) in the expression are the default we set to make sure the report can successfully process. You can set any date existing in your dataset.
Use the expression below to set the visibility of the tablix:
=IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,false,true)
Create a textbox, put the expression below into it:
=IIF(Code.IsDate(Parameters!StartDate.Value,Parameters!EndDate.Value)=0,"","Date invalid")
Save and preview. It looks like below:

Include or create a view in the database and use this view?

Well, I need to get related data of the main table from another related tables, so one way to do that is to use the Include method in Entity Framework to get this related data.
However, I am thinking in another option, create a view in the database and use this view in entity framework. In this way, I avoid the needed of the include, because I think that is expensive in resources. But I am no very sure about that.
I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
For example, if I use the include I have the advantage that I get only one the main record and all the related data I have in the navigation properties, so the info is more shorted.
Which is the advanteges and disadvantages of both methods to get related data in entity framework?
Thank so much.

Hello ComptonAlvaro,
>>I would like to know if the use of views on entity framework is a good idea to improve the performace or is better to use the include.
If your view would use a Join syntax to query master-child relationship tables, it actually is similar with the Include() method which actually results a duplicate records from master table, you could check this
link for detail description.
>>Which is the advanteges and disadvantages of both methods to get related data in entity framework?
One visible difference is that records from Views are not editable by default(if you want edit them, you could refer to this
blog).
In your case, my suggestion that you could use the lazying load which will load the matter table once and disable the trace if you only need to display data.
Regards.
