The parameter 'token' cannot be a null or empty string sharepoint

Hello ,
I am trying to create SharePoint 2013 web app for office 365 using visual studio 2012. when i debug and run the SharePoint custom web app then it show the error ("the parameter 'token' cannot be a null or empty string") in the
TokenHelper.cs file.
Please help me on urgent basis.
Mail me at : [email protected]
Here is the screenshot in the TokenHelper.cs file.
        public static SharePointContextToken ReadAndValidateContextToken(string contextTokenString, string appHostName = null)
            JsonWebSecurityTokenHandler tokenHandler = CreateJsonWebSecurityTokenHandler();
            SecurityToken securityToken = tokenHandler.ReadToken(contextTokenString);
In this section i get that error.
            JsonWebSecurityToken jsonToken = securityToken as JsonWebSecurityToken;

you can go to <yoursiteurl>/_layouts/appregnew.aspx to create a new AppPrincipal, generating a client ID and client secret. Once generated, copy the client ID from that page into your app manifest and web.config.

SharePoint 2013 - The parameter 'token' cannot be a null or empty string

Hi all,
I am trying to create SharePoint 2013 web app for office 365 using visual studio 2012. when I run the SharePoint web
app then it show the error "the parameter 'token'
cannot be a null or empty string" in the TokenHelper.cs file.
this is the url i'm using:
$(function () {
$('#exportToExcelBtn').click(function () {
window.location = "https://xx.sharepoint.com/ENPages/_vti_bin/owssvr.dll?CS=109&Using=_layouts/query.iqy&List={803B55DA-B973-4EF4-92ED-F61DFD016D7C}&View={A6282A16-299E-407D-A25A-14E05AB23AE7}&CacheControl=1";
is it good?
I checked that key "clientID" and "cleantSecret" contains values.
what else can it be?

in order to authenticate the app standard token should be submitted along with the url
check the below url
http://msdn.microsoft.com/en-us/library/office/jj163816(v=office.15).aspx
This combines five other tokens. It initially resolves to SPHostUrl={HostUrl}&SPAppWebUrl={AppWebUrl}&SPLanguage={Language}&SPClientTag={ClientTag}&SPProductNumber={ProductNumber}.
Then each of these tokens resolves. If there is no app web, the portion &SPAppWebUrl={AppWebUrl} is
not present.
Hope that helps|Amr Fouad|MCTS,MCPD sharePoint 2010

Why does my site look nothing like the design and during testing once uploaded to the server?

Why does my site look nothing like the design and during testing once uploaded to the server?,
Im using Muse whichj crashes like you would not beleive, but after much perseverance I got a basic 4 page holding site together, I tested the site and it all looked fine, when I uploaded it to the server it looks nothing like the site I tested, to the point that even the background has changed colour and nothing is in the rite place.

Cannot assign an empty string to a parameter with JDBC type VARCHAR

Hi,
I am seeing the aforementioned error in the logs. I am guessing its happening whenever I am starting an agent instance in PCo. Can somebody explain whats going on?
Regards,

Heres the complete detail from logs -

Sounds like a UI browsing bug (when no path is selected from a catalog tree folder browser) - I would suggest logging a support ticket so that it can be addressed.

GRC 5.3 - Management Report Error: Cannot assign an empty string to host..

Good day Kiran Kandepalli and Others.
I have successfully executed the background jobs -
Full User, Role, Profile Synchronization & a
Full Batch Risk Analysis
When I run the Management Reports I receive the following error -
Error while executing the Job:Cannot assign an empty string to host variable 10.
Has anybody had this error message before?
When I check table VIRSA_CC_PRMVL, variable 10 is set to No in Nullable collumn.

Hi Sahad,
Thanks for your response. I have checked the usr02 table and logs and do not see any empty fields or strings. This process worked for 5.2 but fails in 5.3. Here is the excerpt from the log for the Management Report run. It seems to fail consistenly at a certain point. If I knew what the batch job was looking for in host variable 10 I might be able to resolve the problem. It seems to fail when it starts to report on users.
Thanks.
Dan.

Management Report - Cannot assign an empty string to host variable 10

We ran a Management Report for the first time after completing the User/Role/Profile Full Sync and the user/Role/Profile Batch Risk Analysis. The job failed with the following error:
Oct 16, 2008 12:13:29 PM com.virsa.cc.xsys.bg.BatchRiskAnalysis runBkgMgmReport
WARNING: Exception in Management Report Job: Cannot assign an empty string to host variable 10.
com.sap.sql.log.OpenSQLException: Cannot assign an empty string to host variable 10.
We are on GRC 5.3 support pack 4. Has anybody encountered this error? What does host variable 10 refer to?

I checked our USOBT_C table and we have a lot of empty values. If this is allowed to be empty in SAP and this is the table that is uploaded into CC, why would all the fields in CC tables then be defined as NOT NULL? We suspect that since we had uploaded USOBT_C under 5.2 and if this had been an issue before, it may have been corrected when we upgraded to 5.3 but then the old data is still in our system. Is there an easy way to get around or correct this?
Thanks.

[svn:bz-trunk] 11030: Tweak the deserialization of ASObjects to treat an empty string for the type of an object as null .

Revision: 11030
Author:   [email protected]
Date:     2009-10-20 11:35:02 -0700 (Tue, 20 Oct 2009)
Log Message:
Tweak the deserialization of ASObjects to treat an empty string for the type of an object as null. It appears that there is some logic in the LC remoting code that relies on a non-null class name to always exist. This change reverts to the old behavior of not allowing empty string as a value for the ASObject.namedType.
This should fix bug 2448442 and its duplicates caused by the recent serialization changes.
I don't think this is the perfect fix. Pending further investigation, a better fix would be either:
a. If it's OK to assume that empty string should always mean null for the type of the ASObject, the code that enforces it should be in the setter/getter inside ASObject and not in the deserializer.
b. ASObject doesn't guarantee that a named type exists or is valid. In that sense an empty string is as bad as some random characters that cannot be a valid class name in java, so depending on how disruptive it may be, the fix should be in any logic that uses ASObject.getType().

Hi Pavan,
"In your payload there is no namespace prefix for the elements under PayloadHeader element."
Yes, you are right - but this message is standard AQ Adapter Header message - it's not defined by me. I just used message which was automatically added to my project when I have defined AQ Adapter.
"In your process is the default namespace is same as namespace value of tns ??"
Do you mean targetNamespace? If yes it's different as it points to process "targetNamespace="http://xmlns.oracle.com/PF_SOA_jws/PF_APPS/APPS_PROCESS" (names of application and process have changed as I try different ways to do that)
ns1 is: xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/aq/PF_SOA/PF_APPS/PO_AQ"
"another thing is tns and ns1 should have same values.."
When I create a variable of header type, namespace ns1 is automatically created for it. I set it as property of receive activity. When process is instantiated on the serwer I get the error in which you can see that namespace is tns.
Maybe I'm doing something wrong but I don't see how I could fix this in my process.
You can see that the message I get on the server has nothing in common with the application/project/process names. Is it possible to define such variable?
Regards
Pawel
PS:
In Transformation xsl file, both variables (source and target) has tns namespace for Header and PayloadHeader, and no namespace for subfields.

NULL and Empty String

Hi There,
As far as I know, Null is not the same as an empty string; however, when I try this out, I get some unexpected results (well, at least unexpected for my liking):
SQL> CREATE TABLE TS (MID NUMBER,
2 MDESC VARCHAR2(20) DEFAULT '' NOT NULL);
Table created.
SQL> INSERT INTO TS VALUES(1,'');
INSERT INTO TS VALUES(1,'')
ERROR at line 1:
ORA-01400: cannot insert NULL into ("TT"."TS"."MDESC")So, according to the above scenario, I can't insert an empty string!! However, an empty string is a valid string that doesn't have tuples/data!!
How come Oracle translates the null string '' as NULL?
Thanks

Difference in Null and Empty String

Hi,
I have been wondering about the difference between Null and Empty String in Java. So I wrote a small program like this:
public class CompareEmptyAndNullString {
     public static void main(String args[]) {
          String sNull = null;
          String sEmpty = "";
          try {
               if (sNull.equalsIgnoreCase(sEmpty)) {
                    System.out.println("Null and Empty Strings are Equal");
               } else {
                    System.out.println("Null and Empty Strings are Equal");
          } catch (Exception e) {
               e.printStackTrace();
This program throws Exception: java.lang.NullPointerException
     at practice.programs.CompareEmptyAndNullString.main(CompareEmptyAndNullString.java:10)
Now if I change the IF Clause to if (sEmpty.equalsIgnoreCase(sNull)) then the Program outputs this: Null and Empty Strings are Equal
Can anyone explain why this would happen ?
Thanks in Advance !!

Saish,
Whether you do any of the following code, the JUnit Test always passes: I mean he NOT Sign doesnt make a difference ...
assert (! "".equals(null));
assert ("".equals(null));
You probably have assertions turned off. Note the the assert keyword has nothing to do with JUnit tests.
I think that older versions of JUnit, before assert was a language keyword (which started in 1.4 or 1.5), had a method called assert. Thus, if you have old-style JUnit tests, they might still compile, but the behavior is completely different from what it was in JUnit, and has nothing to do with JUnit at all.
If you turn assertions on (-ea flag in the JVM command line, I think), the second one will throw AssertionError.

Xmltype.getnumberval() Returns "0" when attribute is an empty string.

Hi,
At my workplace we have noticed that when retrieving the value of a numeric attribute of an XML element we are getting "0" when the attribute's value is an empty string (see below for an example script).
We can't find a reference to this in the documentation but I assume this is expected behavior. Has anyone else experienced this and has anyone else used an alternative work around to the following solution that we are using (with the understanding that it is a third party that is sending us the XML so we cannot just do the sensible thing and make sure the XML doesn't contain attributes with no value)?
Solution we are using:
variable := to_number(xml.extract('node()/@numeric_attribute').getstringval());
Example Script:
SET serverout ON
DECLARE
i xmltype;
BEGIN
-- Test statements here
i := xmltype('<element a="" b="1" c="" d="abc" />');
-- Get Number Values
dbms_output.put_line('a=[' || i.extract('node()/@a').getnumberval() || ']*');
dbms_output.put_line('b=[' || i.extract('node()/@b').getnumberval() || ']');
-- Get String Values
dbms_output.put_line('c=[' || i.extract('node()/@c').getstringval() || ']');
dbms_output.put_line('d=[' || i.extract('node()/@d').getstringval() || ']');
-- Get String then perform to_number()
dbms_output.put_line('a (using to_number() on getstringval()=[' || to_number(i.extract('node()/@a').getstringval()) || ']');
dbms_output.put_line('');
dbms_output.put_line('*Even though value of attribute in element is an empty string, the getnumberval() function converts this to a 0');
END;
Thanks.

Yes, I remember seeing a thread or two about that in the past.
Your workaround is probably the best you can come up with if you want to stick to this approach.
Extractvalue() function works too but it is SQL only.
However, bear in mind that those functions are deprecated in your version.
Use XMLQuery to extract scalar values or XMLTable to extract multiple values as relational columns.

What happens when a OUT parameter of a web-service returns an empty string

Hi,
Any idea on how to deal with the situation when a web-service returns an empty string
I get the following System Exception:-
Caused by: java.lang.AssertionError: Attempt to set empty javaType to ticketResponse(out,0) :: fuego.type.FuegoClass$LazyRef@6770f2. It must be null or a valid java type.
It therefore either expects a null value or a valid java type...
Since it goes into a system exception, the activity is not completed and nothing is inserted into the web-service..
How do we resolve this error inside of BPM?

Thanks Ben for your replies.
Before I attempt changing a VI that was written by a client and make a total mess of it, there's something I'd like to point out.
I tried the re-entrant VI approach and that didn't go any further than the VIT approach, and probably for the same reason(s).
The interesting part is that (with the VIT approach) the same VIT is called by another process and it works fine. It is just for the process that has it appear within 2 sub-panels. So the issue is related to having either having two instances spawn at once of the same VIT or it is related to the sub-panels. I think it is the two instances (or copies of the VIT) that causes LV to caugh...
So you are trying to tell me that the above description is accurate and it is because of the private methods...??...
How would I "wrap" those private methods into public ones? The seems to be a piece of this puzzle that I am not yet grasping..
Thanks for your patience and help.

SQLLDR - how to set a default value for an empty string

I'm using SQLLDR to load data from a flat file on Oracle 10g 10.2.0.4 EE, Linux RHEL 4 update 6. Seems like my question is simple, but darned if I can't find the solution.
My source file (comma delimited extracted form a different RDBMS) has some (not all) rows where the output for a string is "", and not NULL. How do I check for empty string and add a default value in the control file? The target column is non-nullable
Here's my current control file - however, the column attributeName where sometimes the source record is "" does not get evaluated as NULL.
load data
infile 'mydata.del'
badfile 'mydata.bad'
discardfile 'mydata.dsc'
into table mydata
fields terminated by "," optionally enclosed by '"'
   TRAILING NULLCOLS
(l_metadata,
company,
className,
attributeName "decode(:vc_attributeName,null, 'none')",
attributeDefault)
{code}
When I tried decode with "", I received the following error:
{code}SQL*Loader-350: Syntax error at line 11.
Expecting "," or ")", found ", 'none')".
attributeName "decode(:vc_attributeName,"", 'none')", {code}
This does not work either:
{code}
load data
infile 'mydata.del'
badfile 'mydata.bad'
discardfile 'mydata.dsc'
into table mydata
fields terminated by "," optionally enclosed by '"'
   TRAILING NULLCOLS
(l_metadata,
company,
className,
attributeName NULLIF attributeName = BLANKS ,"decode(:vc_attributeName,null, 'none')",
attributeDefault) I get the following in the log:

Dealing with an empty string parameter

I'd think this should be simple but is driving me nuts. I have a string parameter (lets call it Foo) that is being passed from my C# application to a CR subreport. For this parameter field I have a formula associated with "Display String" similar to this:
if (IsNull({?Foo}) or (length({?Foo}) = 0)) then
    "Value is empty"
else
    "Value is " + {?Foo}
I can never get the "Value is empty" line to appear! I've tried lots of suggestions:
1. trim and check result equal to '' (two single quotes)
2. test if equal to "".
3. Adding false to Suppress.
It appears that if this parameter is the empty string CR simply does nothing with my formulas and the entire parameter field is skipped.
If I pass "null" (or any other special string) instead of "" from my C# code and then change the above test to check for that value as shown below things work properly.
        if (IsNull({?Foo}) or ({?Foo} = "null") then
However I really don't like testing for a special string as there is the remote possibility that it could be the actual value of the parameter.
Any help most appreciated.
Dick

Not surprised and willing to bet there will be a simple answer to this!
There is something most odd happening when the string value is empty.
Let me answer your questions.
1 - How are you setting your parameter value?
Since I want to be able to pass parameters to the base report as well as its subreports I'm using this method:
        protected void setParameter(string parameterName, object value)
            ParameterFields fields = report.ParameterFields;
            for (int i = 0; i < fields.Count; i++)
                if (fields<i>.Name.Equals(parameterName))
                    string reportName = fields<i>.ReportName;
                    if (string.IsNullOrEmpty(reportName))
                    {   // give to base report
                        report.SetParameterValue(parameterName, value);
                    else
                    {   // give to subreport
                        report.SetParameterValue(parameterName, value, reportName);
2 - What OS and service pack are you on?
Windows XP, SP 3. All updates from MS installed.
My development environment is either of these two:
a. VS 2008. Version 9.0.30729.1 SP. ,NET Framework 3.5 SP1
b. VS 2010 Version 4.0.30319
3 - What platform are you targeting?
For now just running on my XP PC but have tested our app on XP, Win7, and Vista. 32 and 64-bit version of each.
4 - Is this a win or web form application? Win app
5 - What is the version of your CrystalDecisions.CrystalReports.Engine?
Version: 12.2.0.290, Product Type: Full
6 - What is the version of crpe32.dll do you have on your machine?
I only have one instance of this file in this directory:
     C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86
7 - Did you have one of our betas on this machine? No
Edited by: dcowan on Dec 7, 2010 2:10 AM
I needed to finish this so I'm closing it.
In my C# code I placed the following:
                    if (string.IsNullOrEmpty(value))
                        value = "!_Empty_!";
and in the CR formula I used:
       (IsNull({?CoBrandName}) or ({?CoBrandName} = "!_Empty_!"))
Everything is now working just as I want. Not an ideal solution but I gave up.

BaseFileName cannot be nothing or an empty String during Test Connection
