How do I upload a file to WTDocument via code?

[VladiSlav]

Hello everyone, please tell me how to upload a file to WTDocument using Info*Engine?
Or how to use java to create a document and upload a file to it?

Please check if it is works for you.

Thanks

cyang-5, thank you very much for your response, this is what you need.

Please tell me, do You have an example of how to get files from WTDocument, which is located in Windchill?

HI Vadsilav,

Please take a look in this article :

https://www.ptc.com/en/support/article?n=CS18364

Where you will be to create a document a upload a primary content.

Note that you may have to upload first content into server. 

Note also that it is a server side API. it is only working by invoking methodServer like described in this article :

https://www.ptc.com/en/support/article/CS18364

Hope this will help

hlafkir,thank you very much for your help, I had a problem, the document is being created, but the file is not attached, an error is issued:

(wt.pom.pomResource/0) wt.pom.POMInitException: A persistence error occurred. System message follows:
Nested exception is: wt.method.MethodServerException: No active method context

Hi Vadislav,

Did you implement the rmi invocation ? How did you do that ? and where is located your primary content ?

something like this : 

public class CreateDoc implements RemoteAccess {

public static void main(String[] args)
{
// Retrieve a MethodServer remote reference
// from the ServerManager
RemoteMethodServer rms = RemoteMethodServer.getDefault();

// Authenticate using the default
// HTTPLogin Authenticator
rms.setUserName("wcadmin");
rms.setPassword("ts");

try
{
rms.invoke("CreateDocument",
"ext.CreateDoc", null, null, null);
System.out.println("Should have worked, check the MS log");
}
catch (Exception e)
{
e.printStackTrace();
}
}


public static void CreateDocument() throws WTException, SQLException, PropertyVetoException, IOException {

HI Vadislav, 

In my first post, I provided two same article. Sorry for that.

The RMI implemntation is here : 

https://www.ptc.com/en/support/article/CS24105

without that, you will always get the error you're facing..

As said earlier, pleas eimplement your code like this : 

public class CreateDoc implements RemoteAccess {

public static void main(String[] args)
{
// Retrieve a MethodServer remote reference
// from the ServerManager
RemoteMethodServer rms = RemoteMethodServer.getDefault();

// Authenticate using the default
// HTTPLogin Authenticator
rms.setUserName("wcadmin");
rms.setPassword("ts");

try
{
rms.invoke("CreateDocument",
"ext.CreateDoc", null, null, null);
System.out.println("Should have worked, check the MS log");
}
catch (Exception e)
{
e.printStackTrace();
}
}


public static void CreateDocument() throws WTException, SQLException, PropertyVetoException, IOException {

....

hlafkir,I repeated the example https://www.ptc.com/en/support/article/CS24105 , but I get errors:
