• Generated queries contain schema and catalog name

  - by stacker

  I've the same problem as described here In the generated SQL Informix expects catalog:schema.table but what's actually generated is catalog.schema.table which leads to a syntax error. Setting: hibernate.default_catalog= hibernate.default_schema= had no effect. I even removed schema and catalog from the table annotation, this caused a different issues : the query looked like that ..table same for setting catalog and schema to an empty string. Versions seam 2.1.2 Hibernate Annotations 3.3.1.GA.CP01 Hibernate 3.2.4.sp1.cp08 Hibernate EntityManager 3.3.2.GAhibernate Jboss 4.3 (similar to 4.2.3)

• Sending JSON(jQuery) to PHP and decoding it

  - by dscher

  I can't for the life of me figure out what I'm doing wrong. It seems like it should be simple because I can't find anyone else with this issue but I can't figure out to send basic data via javascript(jQuery) to PHP and decode it. For the sake of simplicity, this is what I have: JAVASCRIPT var json_data = { "name" : "john doe" }; $.ajax({ type: "POST", url: "../bin/process.php", dataType: "json", data: json_data }); and my PHP FILE $arr = json_decode("json_data", true); $fp = fopen('data.txt', "w"); fwrite($fp, $arr['name']); fclose($fp); The file I'm writing ends up with nothing in it. If I do an: fwrite($fp, 'test'); I get a file with the word test in it but no matter what I do I don't get the json data I sent. Can someone please share a thorough example of A to Z. Thanks for any help.

• What's the purpose of the maxPostSize for Tomcat's HTTP Connector?

  - by Bytecode Ninja

  According to Tomcat docs: The maximum size in bytes of the POST which will be handled by the container FORM URL parameter parsing. The limit can be disabled by setting this attribute to a value less than or equal to 0. If not specified, this attribute is set to 2097152 (2 megabytes). But what's "the container FORM URL parameter parsing"? Any ideas what is the purpose of "maxPostSize"? Thanks in advance.

• Is there a way in CXF to disable the SoapCompressed header for debugging purposes?

  - by Don Branson

  I'm watching CXF service traffic using DonsProxy, and the CXF client sends an HTTP header "SoapCompressed": HttpHeadSubscriber starting... Sender is CLIENT at 127.0.0.1:2680 Packet ID:0-1 POST /yada/yada HTTP/1.1 Content-Type: text/xml; charset=UTF-8 SoapCompressed: true Accept-Encoding: gzip,gzip;q=1.0, identity; q=0.5, *;q=0 SOAPAction: "" Accept: */* User-Agent: Apache CXF 2.2 Cache-Control: no-cache Pragma: no-cache Host: localhost:9090 Connection: keep-alive Transfer-Encoding: chunked I'd like to turn SoapCompressed off in my dev environment so that I can see the SOAP on the wire. I've searched Google and grepped the CXF source code, but don't see anything in the docs or code that reference this. Any idea how to make the client send "SoapCompressed: off" instead, without routing it through Apache HTTPD or the like? Is there a way to configure it at the CXF client, in other words?

• bridge methods explaination

  - by xdevel2000

  If I do an override of a clone method the compiler create a bridge method to guarantee a correct polymorphism: class Point { Point() { } protected Point clone() throws CloneNotSupportedException { return this; // not good only for example!!! } protected volatile Object clone() throws CloneNotSupportedException { return clone(); } } so when is invoked the clone method the bridge method is invoked and inside it is invoked the correct clone method. But my question is when into the bridge method is called return clone() how do the VM to say that it must invoke Point clone() and not itself again???

• Pass Alot of Parameters on a Form to Action Struts2

  - by Neeraj

  I have been working on migrating a web application from Struts1 to Struts2. I have a simple Form with around 45 Fields (basically a grid with data). I have to capture all those in Struts2 Action.I noticed that in struts2 we have OGNL through which we just write getters setters in action itself by declaring fields locally to get those variables flowing in the request. I cannot write 45 getters/setters in my action, there must be a way to pass whole object(a POJO) from jsp to Action layer. In Struts 1, we normally get a ActionForm Object and/or get request parameters in a map and then populate. Any help or suggestions will be appreciated.

• How to access valuestack objects within struts iterator?

  - by Monika Michael

  I have following code - <s:iterator value="reviews"> <img src="<s:property value="#request.restaurant.portalImage.url" />" /> <s:property value="user.firstName" /> <s:property value="user.lastName" /> <s:property value="rating" /> <s:property value="review" /> </s:iterator> reviews is a list of review objects which contain details of a review, such as rating and name of user. My problem is that i'm not able to access any of the objects present on the valuestack within the loop. Outside the loop <s:property value="#request.restaurant.portalImage.url" /> works correctly. But within the loop it prints null. AFAIK an iterator pushes it's collection on the valuestack so that all ognl expressions resolve against it. But I've used # which means I'm explicitly specifying the root object for resolution. Why is it still not working?

• Source Lookup Path is correct but debugger can't find file (Eclipse EE IDE)?

  - by Greg McNulty

  When debugging stepping over each line does work. Stepping into a function located in another file debugger displays: Source not found. Also displays option for Edit Source Lookup Path... but the correct package is listed there. (Also tried pointing with the directory path.) No other breakpoints set, as is a common solution. Any point in the right direction is helpful. Thank You.

• correct way of initializing variables

  - by OVERTONE

  ok this is just a shot in the dark but it may be the cause of most of the errors ive gotten. when your initializing something. lets say a smal swing program. would it go liek this variables here { private Jlist contactList; String [] contactArray; ArrayList <String> contactArrayList; ResultSet namesList constructor here public whatever() { GridLayout aGrid = new GridLayout(2,2,10,10); contact1 = new String(); contact2 = new String(); contact3 = new String(); contactArrayList = new ArrayList<String>(); // is something supposed too go in the () of this JList? contactList = new JList(); contactArray = new String[5]; from1 =new JLabel ("From: " + contactArray[1]); gridlayout.add(components)// theres too many components to write onto SO. } // methods here public void fillContactsGui() { createConnection(); ArrayList<String> contactsArrayList = new ArrayList<String>(); while (namesList.next()) { contactArrayList.add(namesList.getString(1)); ContactArray[1] = namesList[1]; } } i know this is probably a huge beginner question but this is the code ive gotten used too. im initializing thigns three and fours times without meaning too because im not sure where they gp. can anyone shed some light on this? p.s. sorry for the messy sample code. i done my best.

• Create a triangle out of stars using only recursion

  - by Ramblingwood

  I need to to write a method that is called like printTriangle(5);. We need to create an iterative method and a recursive method (without ANY iteration). The output needs to look like this: * ** *** **** ***** This code works with the iterative but I can't adapt it to be recursive. public void printTriangle (int count) { int line = 1; while(line <= count) { for(int x = 1; x <= line; x++) { System.out.print("*"); } System.out.print("\n"); line++; } } I should not that you cannot use any class level variables or any external methods. Thanks.

• Too much data for RSA block fail. What is PKCS#7?

  - by Tom Brito

  Talking about javax.crypto.Cipher; I was trying to encrypt data using Cipher.getInstance("RSA/None/NoPadding", "BC"); but I got the exception: ArrayIndexOutOfBoundsException: too much data for RSA block Looks like is something related to the "NoPadding", so, reading about padding, looks like CBC is the best approach to use here. I found at google something about "RSA/CBC/PKCS#7", what is this "PKCS#7"? And why its not listed on sun's standard algorithm names?

• How to change the BlackBerry volume, or mute it?

  - by devguy

  My current code is this: int volume = Alert.getVolume(); // reads 100 Alert.setVolume(0); It DOESN'T change the volume setting, like it would be supposed to do :( Even calling Alert.mute(true) doesn't produce any good effect. Audio.setVolume(0) also doesn't work! I'm running this on a Curve 8310. I have another software installed though that successfully manages to lower the volume setting a lot...so I suppose I'm doing something wrong. Any idea?

• Why does Hibernate 2nd level cache only cache queries within a session?

  - by Synesso

  Using a named query in our application and with ehcache as the provider, it seems that the query results are tied to the session within the cache. Any attempt to access the value from the cache for a second time results in a LazyInitializationException We have set lazy = true for the following mapping because this object is also used by another part of the system which does not require the reference... and we want to keep it lean. <class name="domain.ReferenceAdPoint" table="ad_point" mutable="false" lazy="false"> <cache usage="read-only"/> <id name="code" type="long" column="ad_point_id"> <generator class="assigned" /> </id> <property name="name" column="ad_point_description" type="string"/> <set name="synonyms" table="ad_point_synonym" cascade="all-delete-orphan" lazy="true"> <cache usage="read-only"/> <key column="ad_point_id" /> <element type="string" column="synonym_description" /> </set> </class> <query name="find.adpoints.by.heading">from ReferenceAdPoint adpoint left outer join fetch adpoint.synonyms where adpoint.adPointField.headingCode = ?</query> Here's a snippet from our hibernate.cfg.xml <property name="hibernate.cache.provider_class">net.sf.ehcache.hibernate.SingletonEhCacheProvider</property> <property name="hibernate.cache.use_query_cache">true</property> It doesn't seem to make sense that the cache would be constrained to the session. Why are the cached queries not usable outside of the (relatively short-lived) sessions?

• Drawing graphics on top of a JButton

  - by trinth

  I have a situation wherein I have a bunch of JButtons on a GridLayout. I need each of the JButtons to have: a background image (but retain the ability to keep the default button look if needed) custom graphics drawn on top by other classes I have no trouble with the background image, since I am using setIcon() but I am having problems drawing things on top of the background. At one point I was able to draw on top of the button, but after the button was clicked, the drawings disappeared. How can make the button keep this drawing state? Basically, I need a way for my JButtons to have public methods that would allow another class to draw anything on it such as: public void drawSomething() { Graphics g = this.getGraphics(); g.drawOval(3,2,2,2); repaint(); } or public Graphics getGraphics() { return this.getGraphics(); } then another class could do this: button.getGraphics().drawSomething(); The latter is more what I am looking for but the first is equally useful. Is there any way to go about this? Also, overriding the parent class method paintComponent() doesn't help since I need each button to have different graphics.

• Google App Engine - Cannot See Children in Datastore Viewer

  - by Taylor L

  I have the following kinds/relationships in my datastore: UserAccount 1-to-1 PersistentLogin 1-to-many PersistentLogins They are all in the same entity group and UserAccount is the parent. Should I expect to see the other kinds in the datastore viewer? Currently, I only see UserAccount entities, but I'm pretty confident the other entities are there because my code is working as expected. Is this just a nuance of the datastore viewer?

• Send data from Service to Widget on Android.

  - by Jose Vega

  I am writing a widget on Android 1.6 that shows the minutes that a person has used on the current month. The way I have it setup is by having a service that listens to the state of the phone and when the phone is picked up, it starts the timer and when the person hangs up, ends a timer. I would like to send this variable(long duration) over to my appWidgetProvider so I could update the edit text on it.

• Where are the really high quality and complex Swing components?

  - by jouhni

  Looking at Swing, I have the feeling that it comes with many useful and reasonable atomic components in its core. And when I look at the Web there are hundrets of quickly plugged together components (among them many date/time pickers, pimped lists and tables), which have in common that I could easily write them on my own, if I needed them. When I build big software and come to the point where I need a domain-specific component which is really big, I mostly come to the point where I have to write it on my own, which, due to the point that they are not just plugged together lists and tables, isn't done qickly. So, the question is, why are there no Swing component galleries which contain more than just customized date/time pickers or lists with added tree support. Where are the components which really raise the level of abstraction, or are in best case domain-specific?
