  • String.substring(index) has stoped my thread in debug mode.

    - by Arkaha
    Hello! I work with j2me polish 2.0.7, in eclipse 3.4.2, with wtk2.5.2_01. I create control which draws text: normal, bold, and italic. The code below is parsing raw text, and search for * and _ symbols, if found than add to draw vector the text and the drawer, and it's just stops after getting second time to the line 58: String test = new String(raw_text_buff.substring(iter)); it stops in raw_text_buff.substring(iter), ONLY in debug mode.. raw text is: bla bla bla *1000* bla bla Full code: private String raw_text = "bla bla bla *1000* bla bla"; Vector draw_items = null; private void prepareText() { char open_char = 0; int open_pos = 0; Object []param = null; StringBuffer sb = new StringBuffer(); String raw_text_buff = new String(raw_text); int iter = 0; boolean was_reset = false; while(true) { char c = raw_text_buff.charAt(iter); if(iter == raw_text_buff.length() || c == '*' || c == '_') { if(sb.length() > 0) { BmFont viewer = null; String str = sb.toString(); if(open_char == '*' && null != bm_strong) { viewer = bm_strong.getViewer(str); }else if(open_char == '_' && null != bm_italic) { viewer = bm_italic.getViewer(str); }else if(null != bm_normal) { viewer = bm_normal.getViewer(str); }else { } param = new Object[2]; param[0] = str; param[1] = viewer; if(null == draw_items) draw_items = new Vector(); draw_items.addElement(param); sb = new StringBuffer(); if(open_char == 0 && (c == '*' || c=='_')) open_char = c; else open_char = 0; String test = new String(raw_text_buff.substring(iter)); // stucks here. raw_text_buff = test; iter = 0; was_reset = true; }else { open_char = c; } if(iter == raw_text_buff.length()) break; }else { sb.append(c); } ++iter; } } What I'm doing wrong?

  • CascadeType problem in One to Many Relation

    - by Milad.KH
    Hi I have two classes which have a Unidirectional One to Many relation with each other. public class Offer{ ... @OneToMany(cascade=CascadeType.ALL) @JoinTable(name = "Offer_Fields", joinColumns = @JoinColumn(name = "OFFER_ID"), inverseJoinColumns = @JoinColumn(name = "FIELDMAPPER_ID")) private Set<FieldMapper> fields = new HashSet<FieldMapper>(); } public class FieldMapper{ ... } I want to store an Offer with a set of FieldMapper to database. When I Use CascadeType.ALL in my OneToMany, I got this error: org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions and when I change CascadeType to something else I got this error: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.RCSTT.library.FieldMapper Thanks for your help.

  • GAE/J: unable to register a custom ELResolver

    - by dfa
    I need to register a custom ELResolver for a Google App Engine project. Since it must be registered before any request is received, as specified by the Javadoc: It is illegal to register an ELResolver after the application has received any request from the client. If an attempt is made to register an ELResolver after that time, an IllegalStateException is thrown. I'm using a ServletContextListener: public class RegisterCustomELResolver implements ServletContextListener { @Override public void contextInitialized(ServletContextEvent sce) { ServletContext context = sce.getServletContext(); JspApplicationContext jspContext = JspFactory.getDefaultFactory().getJspApplicationContext(context); jspContext.addELResolver(new MyELResolver()); } ... } The problem is that JspFactory.getDefaultFactory() returns always null. I've alreay filled a bug report. Any idea for a workaround?

  • Hibernate orm for a view

    - by EugeneP
    How do you ORM a view? Is there any difference with a table in terms of reverse engineering? In my case, I have a whole pile of joined tables that will be read-only in an application. So, if I need sort of a 1 Object with all collections in proper order, instead of long chains of relationships - collection with another etc, it'll be simpler. What do you think and how do you accomplish this?

  • Android Lightweight HTML Template Engine

    - by Anthoni Gardner
    Hello, I am after a very lightweight template engine that supports / can be embedded inside Android programs. I've looked at the MiniTemplator (I think that is how you spell it) and that looks great but it loads in only from file and I need to load templates from string and I am not fully confident in changing that code lol. Can anyone recommend a very lightweight (preferably no jars, single source files etc) that I can use ? I do not need it to parse XML or anything like, just normal HTML files with keywords embedded into them betwee %% tags etc. Regards Anthoni

  • Locating multiple nested If statements using regular expressions

    - by TERACytE
    Is there a way to search for multiple nested if statements in code using a regular expression? For example, an expression that would locate an instance of if statements three or more layers deep with different styles (if, if/else, if/elseif/else): if (...) { <code> if (...) { <code> if (...) <code> } else if (...) { <code> } else { <code> } } else { <code> }

  • Hibernate: Check if object exists/changed

    - by swalkner
    Assuming I have an object Person with long id String firstName String lastName String address Then I'm generating a Person-object somewhere in my application. Now I'd like to check if the person exists in the database (= firstname/lastname-combination is in the database). If not = insert it. If yes, check, if the address is the same. If not = update the address. Of course, I can do some requests (first, try to load object with firstname/lastname), then (if existing), compare the address. But isn't there a simpler, cleaner approach? If got several different classes and do not like to have so many queries. I'd like to use annotations as if to say: firstname/lastname = they're the primary key. Check for them if the object exists. address is the parameter you have to compare if it stayed the same or not. Does Hibernate/JPA (or another framework) support something like that? pseude-code: if (database.containsObject(person)) { //containing according to compound keys if (database.containsChangedObject(person)) { database.updateObject(person); } } else { database.insertObject(person); }

  • JLayeredPane versus Container layering

    - by Gili
    JLayeredPane allows one to stack multiple Components on top of one another using JLayeredPane.add(Component, Integer). Components in higher "layers" display on top of Components in lower "layers". Container.add(Component, int) provides a similar mechanism whereby Components with lower indexes display on top of Components with higher indexes. Please note that the first mechanism uses Integer and the second mechanism uses int. Also, one renders high values on top of low ones, and the other does the opposite. Do not mix the two :) My question is: what's the point of using JLayeredPane when Container already provides the same mechanism? Does one layer components better than the another? UPDATE: There is also Container.setComponentZOrder(Component, int) to consider.

  • How to get equivalent of ResultSetMetaData without ResultSet

    - by javanix
    Hey Guys - I need to resolve a bunch of column names to column indexes (so as to use some of the nice ResultSetMetaData methods). However, the only way that I know how to get a ResultSetMetaData object is by calling getMetaData() on some ResultSet. The problem I have with that is that grabbing a ResultSet takes up uneccesary resources in my mind - I don't really need to query the data in the table, I just want some information about the table. Does anyone know of any way to get a RSMD object without getting a ResultSet (from a potentially huge table) first? Thanks!

  • Why linking doesn't work in my Xtext-based DSL?

    - by reprogrammer
    The following is the Xtext grammar for my DSL. Model: variableTypes=VariableTypes predicateTypes=PredicateTypes variableDeclarations= VariableDeclarations rules=Rules; VariableType: name=ID; VariableTypes: 'var types' (variableTypes+=VariableType)+; PredicateTypes: 'predicate types' (predicateTypes+=PredicateType)+; PredicateType: name=ID '(' (variableTypes+=[VariableType|ID])+ ')'; VariableDeclarations: 'vars' (variableDeclarations+=VariableDeclaration)+; VariableDeclaration: name=ID ':' type=[VariableType|ID]; Rules: 'rules' (rules+=Rule)+; Rule: head=Head ':-' body=Body; Head: predicate=Predicate; Body: (predicates+=Predicate)+; Predicate: predicateType=[PredicateType|ID] '(' (terms+=Term)+ ')'; Term: variable=Variable; Variable: variableDeclaration=[VariableDeclaration|ID]; terminal WS: (' ' | '\t' | '\r' | '\n' | ',')+; And, the following is a program in the above DSL. var types Node predicate types Edge(Node, Node) Path(Node, Node) vars x : Node y : Node z : Node rules Path(x, y) :- Edge(x, y) Path(x, y) :- Path(x, z) Path(z, y) When I used the generated Switch class to traverse the EMF object model corresponding to the above program, I realized that the nodes are not linked together properly. For example, the getPredicateType() method on a Predicate node returns null. Having read the Xtext user's guide, my impression is that the Xtext default linking semantics should work for my DSL. But, for some reason, the AST nodes of my DSL don't get linked together properly. Can anyone help me in diagnosing this problem?

  • struts2 validate

    - by teehoo
    In Struts2 you can change the method used for execution for an action by changing the method attribute in the following line: <action name="registerVal" class="cz.vutbr.fit.pishotel.model.action.Register" method="execute"> Is it possible to change the validation method used as well, or is the validate method name hardcoded.

  • Android Broadcast Address

    - by Eef
    Hey, I am making a Client Server application for my Android phone. I have created a UDP Server in Python which sits and listens for connections. I can put either the server IP address in directly like 192.169.0.100 and it sends data fine. I can also put in 192.168.0.255 and it find the server on 192.169.0.100. Is it possible to get the broadcast address of the network my Android phone is connected to? I am only ever going to use this application on my Wifi network or other Wifi networks. Cheers

  • ivy dependency on external JAR

    - by Misha Koshelev
    Dear All: I am battling with Ivy (I tried maven but had an event more difficult time setting up the JBoss repository for Hibernate). Quick question - I am using this wonderful package: http://ooweb.sourceforge.net/index.html Unfortunately, the JAR is only available through Sourceforge: http://sourceforge.net/projects/ooweb/files/ooweb/0.8.0/ooweb-0.8.0-bin.tar.gz/download Is there a way to get Ivy to download a specific JAR? For that matter, is it possible to do with Maven? Thank you! Misha

  • Spring 3 MVC - how to turn a form into a query string?

    - by caerphilly
    I have a simple Spring form that gets bound to a form object on post. The http POST handler does some work, and then needs to redirect to a new URL, passing the form data as querystring parameters. So, assuming I have a form backing object with properties "param1" and "param2", I want to build a string that looks something like this: redirect:/app/new/page?param1=value;param2=value Now, Spring will automatically bind values FROM a querystring or a form post into my form object, but I want to GENERATE a querystring with values taken from the form object. Obviously it's trivial to do this manually but since I'm going to have lots of different form backing objects, is there some built-in facility in Spring to generate a query string from a form object, suitable for building into a URL? Thanks.

  • Check if BigInteger is not a perfect square

    - by Ender
    I have a BigInteger value, let's say it is 282 and is inside the variable x. I now want to write a while loop that states: while b2 isn't a perfect square: a ? a + 1 b2 ? a*a - N endwhile How would I do such a thing using BigInteger? EDIT: The purpose for this is so I can write this method. As the article states one must check if b2 is not square.

    3 questions: 1) What is the difference between connection and read timeout for sockets? 2) What does connection timeout set to "infinity" mean? In what situation can it remain in an infinitive loop? and what can trigger that the infinity-loop dies? 3) What does read timeout set to "infinity" mean? In what situation can it remain in an infinitive loop? and what can trigger that the infinity-loop dies?
