PropertySchema existence
|

| eXavier 2005-06-01, 5:52 pm |
| Hi all,
I experience problem when promoting message properties from custom adapter.
I developed my adapter based on SDK samples. It is .NET class library
project type. To be able to deploy adapter's property schema I had to create
also Biztalk project with the schema. If schema is deployed, promoting from
adapter works fine, but if the schema is not deployed I receive error from
IBTTransportBatch.SubmitMessage(): "The parameter is incorrect.". (Code
snippet follows bellow.)
The error brings not much information, so I would like to check if property
schema exists before I try to promote properties. If the schema does not
exist I would just Write() properties into message context (without
promotion). The question is: How could I find out if property schema exists
for given property ?
Thanks a lot
eXavier
Here's code snippet :
IBaseMessagePart part = this.messageFactory.CreateMessagePart();
part.Data = GetMyStream();
IBaseMessage message = this.messageFactory.CreateMessage();
message.AddPart(MESSAGE_BODY_PART_NAME, part, true);
SystemMessageContext context = new SystemMessageContext(message.Context);
context.InboundTransportLocation = this.receiveLocation.uri;
context.InboundTransportType = this.transportType;
string subject = email.Subject as string;
if (subject != null) {
message.Context.Promote("Subject", this.propertyNamespace, subject);
}
StandardReceiveBatchHandler batch = new
StandardReceiveBatchHandler(this.transportProxy, null);
batch.SubmitMessage(message, email.noteid); <<<<< throws Exception
BatchResult batchResult = batch.Done(null);

| Hi,
If you want to get that degree of insight, you can use the BizTalkOM Objekt
model. It is well documented by the online help. However, please not that in
order to be able to use that, the user account you are acting with must be
member of the BizTalk Administrators group.
Sincerely

| You can use the ExplorerOM library, the method you are looking for is:
Microsoft.BizTalk.ExplorerOM.BtsCatalogExplorer _explorer = new
BtsCatalogExplorer();
// Connect the explorer
_explorer.ConnectionString = connectionString; // Very important to set the
connection string to the management db.
_explorer.Schemas[name];
This will return the schema for your desired assembly, to check that it
exists, if it return null, then its not deployed.
To check if your assembly with the schema is deployed, try:
_explorer.Assemblies[name]

| Thanks for your response, but I really don't want to incorporate connection
string to managment database into an adapter. Is using BizTalkOM the only
way how to figure out if the property can be promoted ?

| A simple try catch will do the trick for you, won't it?
Try it the first time, if you fail keep an indication in memory so you don't
have to keep trying.

| If you are using the right user, then integrated security is all you need
for connection sting.

| Not true in our scenario - biztalk database is on dedicated (clustered) DB
server which hosts several installation of biztalk databases, so there are
databases
App1BiztalkMgmtDb, App2BiztalkMgmtDb, ...
