hard reference to heavy resource library does not work as suggested

[Former Member]

Hi All

I've followed the directions of Goran Stoiljkovski in his explanation of how to use "heavy resources" to create a static library. Using telnet, I can see that my library was in fact loaded as a heavy resource. Here's the output:

>ll | grep ionline

[sap.com/ionline_library]

[sap.com/ionline_library-library-loader] <--- This is the proof

and here is the snippet in application-j2ee-engine.xml of my application referring to the library.

<application-j2ee-engine xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="application-j2ee-engine.xsd">
	<reference reference-type="hard">
	<reference-target provider-name="com.sap"
		target-type="application">ionline_library</reference-target>
	</reference>
	<provider-name>com.sap</provider-name>
	<fail-over-enable mode="disable" xsi:type="fail-over-enableType_disable"/>
	<start-up mode="always"/>
</application-j2ee-engine>

In spite of all this, I get the following error when trying to deploy my application:

snip

[ERROR CODE DPL.DS.5035] Application [sap.com/ionline] cannot be started. Reason: it has hard reference to resource [ionline_library] with type [application], which is not active on the server.

snip

The following telnet output shows that the library application IS active:

>add deploy

>list_app | grep ionline

sap.com/ionline IMPLICIT_STOPPED always 3754050

sap.com/ionline_library STARTED lazy 3754050

>

Please, does anyone have a clue as to what is wrong?

Hi Johan

I had not seen the Heavy Resource Reference PDF that you are trying to follow and so I had wondered why you are calling your library an application. But now I see it and am sure that you've used a wrong provider name.

	<reference-target provider-name="com.sap"
		target-type="application">ionline_library</reference-target>
	</reference>

You can confirm this by deploying after changing it to sap.com since your ionline_library is deployed under the vendor name sap.com, which is different to what Goran has deployed under (see pg 15/18 of his PDF: http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/60642a88-95fe-2b10-d387-a245d48fc257&override....

Please inform if it was successful. The "Heavy Resource Reference" concept indeed looks interesting and I would try it as well.

Yes! Varun, you are right. I changed it to sap.com and I no longer have that problem. I have new problems, but I'll start a new thread if I cannot overcome them.

Thanks for your help

Hi Johan

Could you please check whether you've deployed your library as a library or as a j2ee app? If you've deployed it as a library, please check the corresponding folder's presence in ..\j2ee\cluster\server0\bin\ext\ (AS Java 7.0 structure). What is the folder name over there? Is it <vendor_name>~<library_name>?

Also, if it is deployed as a library, please use the "library" reference type and not "application" and make sure that the vendor name and library name in the applications's deployment descriptor are exactly as the folder name pattern, as mentioned above.

Hi Varun

Thank you for your reply. I found an ext folder under C:\usr\sap\CE1\J00\j2ee\cluster\bin\ext. I am running the 32-bit workplace that comes with SAP Netweaver CE 7.1 with EHP1. My library is not there. I followed the directions in [Developer guide|http://help.sap.com/saphelp_nwce711/helpdata/en/46/b902f8d0b22880e10000000a155369/content.htm] and if I use telnet, I see this:
