JavaPOS Questions and Upgrades

[edwinallenz]

Im looking into the changes made on the new JavaPOS on adempiere, its good improvement.
I compiled it and it's running.

I have some, if you can help me.

1. Where is a good point to start learning how to develop some changes for the POS, I would like to make a window for adding a new Business partner from the Java POS and a little alert when the product is out of stok. And also where to learn the coding standars for adempiere.

2. The document "Adempiere JavaPOS" said there is a standalone version of the POS. Where I can find documentation or some help on how to achieve this.

3. I noticed that the prices displayed on Java POS are not working with the disccount schema. I this true? If is it, could you give me a little guide about how to implement this functionality.

Hi edwinallenz,
Maybe this is what you want for the standalone POS viewtopic.php?f=29&t=1356.

Do you know Java? If you do you can checkout the code from the SVN i gave for JavaPOS and check what is the code doing. Making stock alert check and Discount Schema reference is easy, if you are familiar with the ADempiere table model in java code, and the pop up box needs some reference to other JavaPOS code that does pop-up so that you need not reinvent the wheel.

I would be happy if you contribute this back so that any future enhancements from everyone will not override your local instance and you or your client has a hard time upgrading.

Thanks red1 I don't know too much about Adempiere table model, but I'm trying to undertand it with your videos and source code.
I made a little modification to the java pos for showing the stock alert that I want to share.

In SubCurrentLine.java

Code: Select all

if (results.length == 0)
      {
         String message = Msg.translate(p_ctx,  "search.product.notfound");
         ADialog.warn(0, p_posPanel, message + query);
         setM_Product_ID(0);
         p_posPanel.f_curLine.setPrice(Env.ZERO);
      }
      else if (results.length == 1)
      {   //check qty avaliable      
         if (results[0].getQtyAvailable().intValue() <= 0){
                                //less than 0 alert
            ADialog.warn(0, p_posPanel, "Product stock is " + results[0].getQtyAvailable() + ", less than 0.");
         }

...
}


I want to use this POS for a production enviroment, so I want to make some enchacements, right know I'm going to start working on creating a new Business partner window.

wish me luck.

Glancing at it looks OK. Does it show up alright? Then please attach a screenshot here. Thanks for sharing. Keep going, man. I am now in Bogota and heading to Medelin, Quito and Sao Paulo. There are lots of eager supporters, collaborators here also. So you can now welcome to a really huge club. Check out my Facebook trail of my travels here http://www.facebook.com/red1org cheers!

As long as this pop-up does not stop the sale just in case the data is not used. From your code you are only issuing a warning so it should be OK. Or you can make a check at the 'Availability' rule that warns only if it is so and not if it is 'Forced'. In this way the user can have smoother operations without inventory control (for those POS that are lazy or just really standalone without purchasing and inventory).

I was able to create the "New Client" window successfully, I will share the screenshots and source code later.
I have some issues with the JavaPos that I like to solve, if some one can give me a hand or guidance I'll appreciate it.

1. When an "Pos Order" is created from POS or from the "Sales order window", the payment is not allocated. And it increments the client credit.
Any advance on how to create the payment allocation from the POS source code? THIS IS THE MOST IMPORTANT.
2. In the customer field if you press ENTER instead of TAB after you type your text, the custumer is not searched, and the field is reseted.
3. How to navigate with TAB in the Query Product window.
4. Final, Its possible to integrate the Business Partner Info, Product Info, ... views in the POS.

Best regards.

I am not aware of the above issues. AFAIK a processed POS transaction via Java POS is as what i exposed in the tests as reported before i.e. Payment record is created. So i wonder if you get something similar. Perhaps you are right that allocation is deferred and need further follow up action from the user or accounting dept later. I am not that sure of back room accounting needs but i think allowing things to be more loose is better than more tight (further config or customization for particular usage).

I completed the allocation in the POS.
This is what I did:

1. In the payOrder() function in sub current line, add a call to a new function to create the payment allocation, in my case PosAllocation(), this function have to be called after the payment is completed
Sample code

Code: Select all

   private void payOrder() {

      //Check if order is completed, if so, print and open drawer, create an empty order and set cashGiven to zero

      if( p_posPanel.m_order != null ) //red1 wrong action flow below
      {
         PosPayment pay = PosPayment.pay(p_posPanel);
         if (!pay.isPaid() )
            return; //red1 not paid (cancelled) cannot continue process the order.
         
         if (!p_posPanel.m_order.isProcessed() && !p_posPanel.m_order.processOrder() )
         {
            ADialog.warn(0, p_posPanel, "PosOrderProcessFailed");
            return;
         }
         else
         {
            
            printTicket();
            PosAllocation();
            p_posPanel.setOrder(0);
         }
      }   
   }



2. Create the posAllocation function in SubCurrentLine class as follows

Code: Select all

public boolean PosAllocation()
   {
      //Master allocation
      m_allocation = new MAllocationHdr (Env.getCtx(), false, p_posPanel.m_order.getDateAcct(),   //   automatic
            p_posPanel.m_order.getC_Currency_ID(), "Pos order " + p_posPanel.m_order.getC_Order_ID(),trxName);
         m_allocation.setAD_Org_ID(p_posPanel.m_order.getAD_Org_ID());
         if (!m_allocation.save())
            return false;
         
      //Allocation detail
      MAllocationLine aLine = new MAllocationLine (m_allocation, p_posPanel.m_order.payment.getPayAmt(),
            Env.ZERO, Env.ZERO, Env.ZERO);
      aLine.setC_BPartner_ID(p_posPanel.m_order.getC_BPartner_ID());
      aLine.setC_Payment_ID(p_posPanel.m_order.payment.get_ID());
      aLine.setC_Invoice_ID(p_posPanel.m_order.getC_Invoice_ID());
      if(! aLine.save())
         return false;         
      m_allocation.processIt(MAllocationHdr.DOCACTION_Complete);
      if (!m_allocation.save())
         return false;
      return true;
   }

I need to make a new improvement, I want to be able to select with a ComboBox some Order Document Types, in this case I need Pos Order, On credit order and Quotation. I think I have to change the document type when the POS create de document but I'm wondering how to fill the ComboBox with the document types I need. I explored the X_C_DocType class but I didn't find a function to get the Types asociated with a GL_Category.

Thanks in advance.
