Adding a document to another document via java service

Question

I am writing a java service where I create a document for output. But my structure should be: OutPut Doc is a top-level document. Inside, what I want another Doc to say is an Intermediate doc, and in this intermediate document I want Key values.

But my question is: how can I insert one document into another. I see that IDataUtil has a put method that requests the key as a string and the value can be an object.

My IDataUtil.put(idcvalueDoc, "Body", FullValue.toString()); code IDataUtil.put(idcvalueDoc, "Body", FullValue.toString());

But this Body should not be a line, it should be a document. I want to insert one Doc into another.

Please help me

Answer 1

To accomplish what you need, you will need to do the following:

• Create an IDD Intermediate Document Object
• Add key tuple values ​​to middleDoc as needed
• Create IDDDoc Object
• Add intermediate doc as root key value in outputDoc
• Add outputDoc to the pipeline

The following is an example of a Java service that demonstrates this (note that the root key values ​​added to middleDoc are hardcoded here for convenience):

 public static final void exampleService(IData pipeline) throws ServiceException { IDataCursor pipelineCursor = pipeline.getCursor(); try { // create an intermediateDoc IData object IData intermediateDoc = IDataFactory.create(); // create a cursor to use to add key value tuples to the intermediateDoc IDataCursor intermediateCursor = intermediateDoc.getCursor(); // add key value tuples as required to the intermediateDoc IDataUtil.put(intermediateCursor, "key1", "value1"); IDataUtil.put(intermediateCursor, "key2", "value2"); // ... // destroy the intermediateCursor when done adding key value tuples intermediateCursor.destroy(); // create an outputDoc IData object IData outputDoc = IDataFactory.create(); // create a cursor to use to add key value tuples to the outputDoc IDataCursor outputCursor = outputDoc.getCursor(); // add the intermediateDoc to the outputDoc IDataUtil.put(outputCursor, "intermediateDoc", intermediateDoc); // destroy the outputCursor when done adding key value tuples outputCursor.destroy(); // add the outputDoc to the pipeline IDataUtil.put(pipelineCursor, "outputDoc", outputDoc); } finally { // destroy the pipelineCursor pipelineCursor.destroy(); } }

With wmboost-data, you can write the following:

 public static final void exampleService(IData pipeline) throws ServiceException { Document outputDoc = Documents.create(); Document intermediateDoc = outputDoc.docEntry("intermediateDoc").putNew(); intermediateDoc.entry("key1").put("value1"); intermediateDoc.entry("key2").put("value2"); Documents.wrap(pipeline).entry("outputDoc").put(outputDoc); } 

Code:

• Creates a top-level document, outputDoc
• Creates a middleDoc as a subdocument (an alternative is to create it yourself and attach it to the parent content)
• Assigns input values ​​to an intermediate Doc
• Adds outputDoc to the pipeline

Input / output assumptions and design

Assuming that

• A ValuesInput[] document is input that is the same as Values[] output.
• The columnValue document in the Document ValuesInput[] document has a string variable called additionalString (which would be pointless if there is no variable inside / under the document)

So, in general, it would be like this:

Of course, you can generate the code after designing the input / output by right-clicking with the mouse and generate the code → To implement this service.

But instead of using the generated code, I'm trying to give an example with IDataMap, which you can find in webMethods Javadoc com.softwareag.util.IDataMap . Which is very convenient to use.

IDataMap

IDataMap combines the functionality of IData , IDataCursor , IDataUtil , and IDataFactory . IDataMap implements the java.util.Map Java Collections Framework interface, providing a familiar and simple interface. IDataMap extends the map interface by adding getAs<Type> methods that convert the return value to a specific type.

And this happens as follows:

 public static final void mapDocument(IData pipeline) throws ServiceException { // pipeline input by IDataMap IDataMap pipelineMap = new IDataMap(pipeline); // extracting Values input into IData[] variable array IData[] ValuesInput = pipelineMap.getAsIDataArray("ValuesInput"); // Initiate OutDoc.Values length based on ValuesInput length IData[] Values = new IData[ValuesInput.length]; // OutDoc.Values // Iterate and copying all ValuesInputDoc into OutDoc.Values for (int i = 0; i < ValuesInput.length; i++) { Values[i] = IDataUtil.clone(ValuesInput[i]); } // OutDoc IData OutDoc = IDataFactory.create(); IDataMap outDocMap = new IDataMap(OutDoc); // OutDoc IDataMap String TableName = "TableName is Never assigned"; outDocMap.put("TableName", TableName); // OutDoc.Values outDocMap.put("Values", Values); // Wrap the OutDoc into pipeline pipelineMap.put("OutDoc", OutDoc); } 

And the result

Just check if any of the following actions in the WmPublic package help:

 pub.list:appendToDocumentList 

or

 pub.document:insertDocument
