Cannot assign a ... length 0 to host variable 4

[Former Member]

In step 4. Generate of the Integration Scenario Configurator for the "CheckFlightSeatAvailability" example (actually, for any scenario), I obtain the following error:

"Cannot assign a com.sap.aii.utilxi.blob.api.InputStreamLoc object of length 0 to host variable 4"

Can anyone tell me what might be wrong?

Hi,

Go to the J2EE home page using the following link.

http://<servername>:<port>/index.html

Then click on the system information link.Over here we can find the SP level of the J2ee engine.

Hi Stephan

I believe I understand what it is you are asking me to do regards xi and j2ee versions being out of sync. I am going to try your suggestion to see if it solves my problem. I will document the steps below for the others.

1. Find the SAP J2EE Engine/6.40 PatchLevel

Browser -> SLD -> Administration -> Details

result = SAP J2EE Engine/6.40 PatchLevel 92160.313

therefor patch level is 9.

2. Find the SAP ABA 640 patch level

Browser -> SLD -> Technical Landscape -> XI tech system

-> Installed Software Components

result = SAP ABA 640 0012

therefor patch level is 12.

3. Find the SAP BASIS 6.40 patch level

Browser -> SLD -> Technical Landscape -> XI tech system

-> Installed Software Components

result = SAP BASIS 6.40 0012

therefor patch level is 12.

Thus, I need to upgrade the SAP J2EE Engine/6.40 PatchLevel from 9 to 12 so that all are in sync.

I obtain the update from http://sapservicemarketplace/swdc

under "support packages and patches" SAP WAS 6.40.

Once I have done this, I will confirm if this solves the error I am experiencing.

Please let me know if this is the path you intended me to travel Stephan when you spoke of XI and J2ee being out of sync.

Thanks

Hi Graham,

the error typically occurs when XIs SP level is behind that of J2EE-engine (not ahead). Moreover, I am not sure whether this error can really occur for J2EE-engine being at SP level 9.

Have you checked the links described by me (for XI) and Sulakshana (for J2EE engine) to determine the SP levels?

I am pretty sure that you will find out that Integration Builders SP-level is behind that of J2EE engine.

Hi Everyone

Resolved the issue as follows:

Applied SP 13 to all components as per the XI section of the SAP PDF document "Applying Support Packages in SAP Netweaver 04 Scenarios" from sap service mktplace/sp-stacks.

Thanks to all for your help and input.

I have seen something more.

In the Integration Builder-Administration-Software Build Information, for Repository and Directory it says jdk.version=1.3.1, since I am running Java 2 Runtime Environment, Standard Edition (build 1.4.2), I believe I'm in the case that Stephan states.

What's the recommendation then? downgrade J2SE? it might affect some other applications. Upgrade XI components? is that possible?

[Former Member]

Hi,

I am not talking about the jdk-version.

On the adminstration page directly above the line indicating the jdk-version there should be a line displaying the 'SP-Number'. There should be a number between 0 and 13 (just one or two digits).

That the SP-level of XI you are running on the Integration Builder. I do not know how to determine the SP-level of the J2EE-engine. Maybe someone else can help.

However these two levels have to be identical.

Hi Stephan,

Do you mean a difference between Java Runtime and SAP J2EE Engine? In Graham case and mine there is a difference.

In my case:

XI Directory and XI Repository

Server:

General:

Server Version: SAP J2EE Engine 6.40 PatchLevel 92160.313

System Environment:

Java Runtime: Java(TM) 2 Runtime Environment, Standard Edition (version=1.4.2)

Java Virtual Machine: Classic VM (version=1.4.2)

Operating System: AIX (version=5.3, arch=ppc64)

I believe that by looking at sld - Administration - Details), you are seeing the same information reported as Server Version. Anyways, in my case:

J2EE Server: SAP J2EE Engine/6.40 PatchLevel 92160.313

Thnx

I get the same error Enrique.

Have you managed to solve this yet ?

Unfortunately, not yet, I still have the problem.

As it occurs when saving, I thought it might be related to the persistence configuration of SLD, I changed to the different modes (Java, ABAP, FileSystem) but I obtained the same result.

[Former Member]

Hi Enrique,

this error typically occurs when you have upgraded your J2EE engine to a higher SP level then XI. Please be aware that the SP levels should always be in sync.

Hi Stephan

Can you tell me how to verify that my SP levels for J2EE engine and XI are in sync with each other.

Thanks

[Former Member]

Hi Graham,

I am not an expert on J2EE engine. So I do not know how to determine its SP level.

For XI just go to the start page of the integration builder. There is a link 'Administration'.

Follow this link, and you should be able to see the SP level (together with some other adminstrative information).

Hi Stephan

our specs are as follows:

J2EE Server: SAP J2EE Engine/6.40 PatchLevel 92160.313

(viewed by clicking: sld - Administration - Details)

XI Directory and XI Repository

Server:

General:

Server ID chqsap00_XI1_00

Server Version SAP J2EE Engine 6.40 PatchLevel 92160.313

System Enviroment:

Java Runtime Java(TM) 2 Runtime Environment, Standard Edition (version=1.4.2_06-b03)

Java Virtual Machine Java HotSpot(TM) Server VM (version=1.4.2_06-b03)

Operating System Windows 2003 (version=5.2, arch=x86)

Can you see a discrepancy ?
