  1. POI can't see the JFrame components until the end of dataset mapping. Why?
    text
    copied!<p>I have developed a piece of software that creates an Ontology using neo4j. Once the ontology is built, I start mapping the dataset of 2 million rows to it, which takes more or less 20 minutes to be completed. As a result, I wished to add a JFrame that shows the process execution. The code below creates at the beginning the JFrame and then it starts mapping the dataset. However, I can see during the execution the JFrame, but its components appears inside the JFrame after the mapping finishes. I have read that the problem might be due to the lack of a thread that surrounds the code. Can anyone help me in solving this matter?? </p> <pre><code>void createGraphDataset(String [][] choices , final ArrayList&lt;String[]&gt; DatabaseFile, GraphDatabaseService BORO_DB){ JFrame converterFrame = new JFrame(); converterFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); converterFrame.setBounds(100, 100, 650, 288); JPanel contentPane = new JPanel(); contentPane.setLayout(null); contentPane.setVisible(true); converterFrame.getContentPane().add(contentPane); JPanel panelNeo1 = new JPanel(); panelNeo1.setBounds(6, 6, 638, 254); panelNeo1.setVisible(true); contentPane.add(panelNeo1); panelNeo1.setLayout(null); JLabel labelNeo1 = new JLabel("CSV BORO Converter"); labelNeo1.setBounds(16, 19, 260, 37); panelNeo1.add(labelNeo1); labelNeo1.setVisible(true); JPanel panelNeo2 = new JPanel(); panelNeo2.setBounds(16, 60, 605, 167); panelNeo1.add(panelNeo2); panelNeo2.setLayout(null); panelNeo2.setVisible(true); /* JProgressBar progressBar = new JProgressBar(); progressBar.setBounds(27, 89, 547, 20); panelNeo2.add(progressBar); panelNeo2.setVisible(true); */ JLabel labelNeo2 = new JLabel(" Processing: Number of row"); labelNeo2.setOpaque(true); labelNeo2.setBounds(28, 36, 184, 20); panelNeo2.add(labelNeo2); labelNeo2.setVisible(true); JLabel labelNeo3 = new JLabel(""); labelNeo3.setBounds(212, 36, 76, 20); panelNeo2.add(labelNeo3); labelNeo3.setVisible(true); JLabel labelNeo4 = new JLabel(); labelNeo4.setText(String.valueOf(DatabaseFile.size())); labelNeo4.setBounds(311, 36, 70, 20); panelNeo2.add(labelNeo4); labelNeo4.setVisible(true); JLabel labelNeo6 = new JLabel("of"); labelNeo6.setBounds(288, 36, 23, 20); panelNeo2.add(labelNeo6); labelNeo6.setVisible(true); converterFrame.setVisible(true); TopNode= new Node [DatabaseFile.get(0).length]; //Create TopNodes Transaction tx0 = BORO_DB.beginTx(); try{ for(int u =0; u&lt;DatabaseFile.get(0).length;u++){ TopNode[u]=BORO_DB.createNode(); TopNode[u].setProperty("name", choices[u][0]); } tx0.success(); } finally{ tx0.finish(); } //Create the database for(int i =0; i&lt;DatabaseFile.size();i++){ Transaction tx2 = BORO_DB.beginTx(); try { // Nodes for each row Node []graphNode= new Node [DatabaseFile.get(i).length]; // Relationships for each row ingoing Relationship [] graphRelOn = new Relationship [DatabaseFile.get(i).length-1]; // Relationships for each row outgoing Relationship [] graphRelOut = new Relationship [DatabaseFile.get(i).length-1]; //Relationship to TopNode ingoing Relationship TopNodeRelIn[]=new Relationship [DatabaseFile.get(i).length]; //Creates Nodes for row and relationship to TopNode for(int j=0; j&lt;DatabaseFile.get(i).length;j++){ //Stores Database values String []ValuesRow =DatabaseFile.get(i); //Creates nodes for 1 row graphNode[j] = BORO_DB.createNode(); graphNode[j].setProperty("name", ValuesRow[j]); //From row to TopNode Relationship (enter) TopNodeRelIn[j]=graphNode[j].createRelationshipTo(TopNode[j], RelTypes.typeInstances); TopNodeRelIn[j].setProperty("relationship-type", "typeInstances"); } //Creates Relationships for(int k=0; k&lt;(DatabaseFile.get(i).length)-1;k++){ //Between same elements of the same row (left to right) graphRelOn[k]=graphNode[k].createRelationshipTo(graphNode[k+1], RelTypes.relatesTo); graphRelOn[k].setProperty("relationship-type", "relatesTo"); //Between same elements of the same row (right to left) graphRelOut[k]=graphNode[(DatabaseFile.get(i).length)-1].createRelationshipTo(graphNode[(DatabaseFile.get(i).length)-(2+k)], RelTypes.relatesTo); graphRelOut[k].setProperty("relationship-type", "relatesTo"); } tx2.success(); } finally { tx2.finish(); } } } </code></pre>
