i have deployed my Custom pipeline and when i tried to use it it gives me the below error

There was a failure executing the receive pipeline: "BizTalk_Server_Project22.ReceivePipeline123, BizTalk Server Project22, Version=1.0.0.0, Culture=neutral, PublicKeyToken=2f421c0b0e473f3a" Source: "Unknown " Receive Port: "ReceivePort8" URI: "E:\rcv\gvgvg\*.xml" Reason: The pipeline component ClassLibrary123.filename,ClassLibrary123, Version=1.0.0.0, Culture=neutral, PublicKeyToken=7cd997faca10c5d6 can not be found. If the component name is fully qualified, this error may occur because the pipeline component can not be found in the assembly.  

I have build the custom pipeline project placed the dll in the pipleine components and gac the same dll but i still get the below error 

can you help me with this?

Have you restarted your Host Instance(s) after GAC'en the DLL?

Also are you 100% sure that the assembly (ClassLibrary123) residing in your GAC also includes a Pipeline Component Class named "filename"?

Try removing the DLL from the "Pipeline Components" folder also. You should use the GAC only, since having the assemblies in that folder can "confuse" BizTalk at times.

Check whether the Fully Qualified name of the assembly is correct.

Restart the relevant host instance of the receive port.

Keep in a break point and check whether the code is stepping in.

I have redeployed the file in GAC and restarted the Host instances,still no luck for me:(

I hope this because of a typo in assembly name.

Please re-check the below assembly name and class name.

ClassLibrary123.filename,ClassLibrary123, Version=1.0.0.0, Culture=neutral, PublicKeyToken=7cd997faca10c5d6

or just copy it from the properties of pipeline component in admin console.

Name, Assembly Name.

Do not put the Assembly in the %\Pipeline Components folder.  Pipeline Components should be in the GAC only.

See here: BizTalk: Deploying Custom Pipeline Components in BizTalk Server 2006 and Higher

Make sure you're trying to put it in the correct GAC location. You cannot drop CLR 4.0 Assemblies in the Assemblies folder.

You muse use gacutil.exe to properly GAC any Assembly.  There is an example in the above Wiki Article along with all other steps to use a custom Pipeline Component.
