  • RS 232 Communication in ASP.NET 3.5?

    - by Pandiya Chendur
    using ASP.NET 3.5 WebForm using C# 3.0, is it possible to setup a RS 232 communication with a device? I need the WebForm to be able to read and write data to the serial port. I would appreciate if there are some good examples, thanks. I understand that under Components, there is a SerialPort .NET Component, but it seems to me that it can only be used in a Windows application (WinForm). Or the only solution is to rely on the ActiveComport Serial Port Toolkit, as from http://www.activexperts.com/activcomport/howto/aspnetc/ ?

  • Swap image with jquery and show zoom image

    - by Neil Bradley
    Hi there, On my site I have 4 thumbnail product images that when clicked on swap the main image. This part is working okay. However, on the main image I'm also trying to use the jQZoom script. The zoom script works for the most part, except that the zoomed image always displays the zoom of the first image, rather than the one selected.

  • Jersey (Jax-RS) & EL

    - by smeg4brains
    Hi there! im trying to get a controller to return a view through a Expression Language-Filter, but have no idea on how to get jersey to use EL for filtering a view. View with EL-tags: <html> <title>%{msg}</title> </html> Controller: @GET @Produces("text/html") public Response viewEventsAsHtml(){ String view=null; try { view=getViewAsString("events"); }catch(IOException e){ LOG.error("unable to load view from file",e); return null; } Response.ResponseBuilder builder=Response.ok(view, MediaType.TEXT_HTML); return builder.build(); } How would one go about in order to get the controller to replace the ${msg} part in the view by some arbitrary value?

  • how to send JSON data with server error response code 500

    - by kapil.israni
    I wanted to know if theres a way to send a JSON data along with HTTP response code 500. Basically I want my rest client to know that there is some error on the backend and along with it send a JSON error data structure like this. {"error" : [ {"code": "1001", "desc": "Some error description"}, {"code": "1002", "desc": "Some other error description"} ] } This is using the following java stack = Java 6/JAX-RS/Jersey/Tomcat If not, then is there a way to send a custom response code along with JSON data. Basically looking from JAX-RS API it looks that you can only send JSON data along with 200 OK?? Any thoughts?? I am guessing RESTEasy would be the same, right??

  • AM I using DO WHILE NOT and EOF in VBscript Properly

  • Lookup function not working (RS SP2)

    - by Al Reyes
    Hi, I made the upgrade to SP2. I'm trying to use the Lookup function to link data from two different servers. I'm trying first a simple exercise linking data from two datasets from the same server, having one dataset with journals and the other with the account description. My Expression looks like this at a field on the table I have: =Lookup(Fields!ACTINDX.Value,Fields!ACTINDX.Value,Fields!ACTDESCR.Value,"ACCTINFO") I made sure of the names and using only uppercases for datasets and fields but I'm receiving the following message when I try to preview: "An error occurred during local report processing. The definition of the report '/DETAIL' is invalid. The Value expression for the text box 'ACTINDX' refers to the field 'ACTDESCR'. Report item expressions can only refer to fields within the current dataset scope or, if inside an aggregate, the specified dataset scope". I'll appreciate any suggestions. Regards, Al

  • Jersey 2 Integrated in GlassFish 4

    - by arungupta
    JAX-RS 2.0 has released Early Draft 3 and Jersey 2 (the implementation of JAX-RS 2.0) released Milestone 5. Jakub reported that this milestone is now integrated in GlassFish 4 builds. The first integration has basic functionality working and leaves EJB, CDI, and Validation for the coming months. TOTD #182 explains how to get started with creating a simple Maven-based application, deploying on GlassFish 4, and using the newly introduced Client API to test the REST endpoint. GlassFish 4 contains Jersey 2 as the JAX-RS implementation. If you want to use Jersey 1.1 functionality, then Martin's blog provide more details on that. All JAX-RS 1.x functionality will be supported using standard APIs anyway. This workaround is only required if Jersey 1.x functionality needs to be accessed. Here are some pointers to follow JAX-RS 2 Specification Early Draft 3 Latest status on specification (jax-rs-spec.java.net) Latest JAX-RS 2.0 Javadocs Latest status on Jersey 2 (jersey.java.net) Latest Jersey API Javadocs Latest GlassFish 4.0 Promoted Build Follow @gf_jersey Provide feedback on Jersey 2 to [email protected] and JAX-RS specification to [email protected].

  • Apache CXF REST Services w/ Spring AOP

    - by jconlin
    I'm trying to get Apache CXF JAX-RS services working with Spring AOP. I've created a simple logging class: public class AOPLogger{ public void logBefore(){ System.out.println("Logging Before!"); } } My Spring configuration (beans.xml): <aop:config> <aop:aspect id="aopLogger" ref="test.aop.AOPLogger"> <aop:before method="logBefore" pointcut="execution(* test.rest.RestService(..))"/> </aop:aspect> </aop:config> <bean id="aopLogger" class="test.aop.AOPLogger"/> I always get an NPE in RestService when a call is made to a Method getServletRequest(), which has: return messageContext.getHttpServletRequest(); If I remove the aop configuration or comment it out from my beans.xml, everything works fine. All of my actual Rest services extend test.rest.RestService (which is a class) and call getServletRequest(). I'm just trying to just get AOP up and running based off of the example in the CXF JAX-RS documentation. Does anyone have any idea what I'm doing wrong? Thanks!

  • Jersey 2 in GlassFish 4 - First Java EE 7 Implementation Now Integrated (TOTD #182)

    - by arungupta
    The JAX-RS 2.0 specification released their Early Draft 3 recently. One of my earlier blogs explained as the features were first introduced in the very first draft of the JAX-RS 2.0 specification. Last week was another milestone when the first Java EE 7 specification implementation was added to GlassFish 4 builds. Jakub blogged about Jersey 2 integration in GlassFish 4 builds. Most of the basic functionality is working but EJB, CDI, and Validation are still a TBD. Here is a simple Tip Of The Day (TOTD) sample to get you started with using that functionality. Create a Java EE 6-style Maven project mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo.archetypes -DarchetypeArtifactId=webapp-javaee6 -DgroupId=example -DartifactId=jersey2-helloworld -DarchetypeVersion=1.5 -DinteractiveMode=false Note, this is still a Java EE 6 archetype, at least for now. Open the project in NetBeans IDE as it makes it much easier to edit/add the files. Add the following <respositories> <repositories> <repository> <id>snapshot-repository.java.net</id> <name>Java.net Snapshot Repository for Maven</name> <url>https://maven.java.net/content/repositories/snapshots/</url> <layout>default</layout> </repository></repositories> Add the following <dependency>s <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.10</version> <scope>test</scope></dependency><dependency> <groupId>javax.ws.rs</groupId> <artifactId>javax.ws.rs-api</artifactId> <version>2.0-m09</version> <scope>test</scope></dependency><dependency> <groupId>org.glassfish.jersey.core</groupId> <artifactId>jersey-client</artifactId> <version>2.0-m05</version> <scope>test</scope></dependency> The complete list of Maven coordinates for Jersey2 are available here. An up-to-date status of Jersey 2 can always be obtained from here. Here is a simple resource class: @Path("movies")public class MoviesResource { @GET @Path("list") public List<Movie> getMovies() { List<Movie> movies = new ArrayList<Movie>(); movies.add(new Movie("Million Dollar Baby", "Hillary Swank")); movies.add(new Movie("Toy Story", "Buzz Light Year")); movies.add(new Movie("Hunger Games", "Jennifer Lawrence")); return movies; }} This resource publishes a list of movies and is accessible at "movies/list" path with HTTP GET. The project is using the standard JAX-RS APIs. Of course, you need the trivial "Movie" and the "Application" class as well. They are available in the downloadable project anyway. Build the project mvn package And deploy to GlassFish 4.0 promoted build 43 (download, unzip, and start as "bin/asadmin start-domain") as asadmin deploy --force=true target/jersey2-helloworld.war Add a simple test case by right-clicking on the MoviesResource class, select "Tools", "Create Tests", and take defaults. Replace the function "testGetMovies" to @Testpublic void testGetMovies() { System.out.println("getMovies"); Client client = ClientFactory.newClient(); List<Movie> movieList = client.target("http://localhost:8080/jersey2-helloworld/webresources/movies/list") .request() .get(new GenericType<List<Movie>>() {}); assertEquals(3, movieList.size());} This test uses the newly defined JAX-RS 2 client APIs to access the RESTful resource. Run the test by giving the command "mvn test" and see the output as ------------------------------------------------------- T E S T S-------------------------------------------------------Running example.MoviesResourceTestgetMoviesTests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.561 secResults :Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 GlassFish 4 contains Jersey 2 as the JAX-RS implementation. If you want to use Jersey 1.1 functionality, then Martin's blog provide more details on that. All JAX-RS 1.x functionality will be supported using standard APIs anyway. This workaround is only required if Jersey 1.x functionality needs to be accessed. The complete source code explained in this project can be downloaded from here. Here are some pointers to follow JAX-RS 2 Specification Early Draft 3 Latest status on specification (jax-rs-spec.java.net) Latest JAX-RS 2.0 Javadocs Latest status on Jersey (Reference Implementation of JAX-RS 2 - jersey.java.net) Latest Jersey API Javadocs Latest GlassFish 4.0 Promoted Build Follow @gf_jersey Provide feedback on Jersey 2 to [email protected] and JAX-RS specification to [email protected].

  • Jersey, Apache HTTPD, and javax.annotation.security usage

    - by Nick Klauer
    So I'm having a heck of a time trying to piece together what I think is a pretty simple implementation. This is very similar to another StackOverflow question only I can't leverage Tomcat to handle role based authentication. I have an Apache httpd server in front of my app that handles authentication and then passes LDAP roles to a Jersey service through Headers. I've created a servlet filter to parse the header and tease out the roles the request came from, which works fine globally to the app, but isn't fine-grained enough to dictate what an Admin could do that a User could not. I'm thinking I could use the javax.annotation.security annotations that JAX-RS supports, but I don't know how to take what I've parsed out using a servlet filter to set or instantiate the SecurityContext necessary for the roles @RolesAllowed.

  • How to prevent "Local transaction already has 1 non-XA Resource" exception?

    - by Zeratul
    Hi, I'm using 2 PU in stateless EJB and each of them is invoked on one method: @PersistenceContext(unitName="PU") private EntityManager em; @PersistenceContext(unitName="PU2") private EntityManager em2; @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) public void getCandidates(final Integer eventId) throws ControllerException { ElectionEvent electionEvent = em.find(ElectionEvent.class, eventId); ... Person person = getPerson(candidate.getLogin()); ... } @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW ) private Person getPerson(String login) throws ControllerException { Person person = em2.find(Person.class, login); return person; } Those methods are annotated with REQUIRES_NEW transcaction to avoid this exception. When I was calling these method from javaFX applet, all worked as expected. Now I'm trying to call them from JAX-RS webservice (I don't see any logical difference as in both cases ejb was looked up in initial context) and I keep getting this exception. When I set up XADatasource in glassfish 2.1 connection pools, I got nullpointer exception on em2. Any ideas what to try next? Regards

  • Jersey message body reader not found in maven-built JAR

    - by Olvagor
    My application uses a REST (JAX-RS Jersey) interface. When I run it in Eclipse, everything' s fine. The domain objects are annotated, I'm not using XML files for the REST mapping. Now I created a standalone JAR using the maven-assembly-plugin, which packs the application and all dependencies in a single, executable JAR file. This also seems to work. But when I start the application and request an object from the server, Jersey complains, that it can't find a message body reader: com.sun.jersey.api.client.ClientHandlerException: A message body reader for Java type, class de.rybu.atuin.core.entity.User, and MIME media type, application/json, was not found Any ideas why this happens? EDIT: After I slept a night over it, I noticed that it complains about JSON... but I'm using only XML for serialization. Strange.

  • Validation of method parameters

    - by Anton Tsivarev
    I have a RESTful web service. For implementation using JAX-RS (Jersey). Have the following method: public void foo (@PathParam ("name") String uuid) { ... } I need to do validation of input parameters. And if data invalid throw WebApplicationException. I added my custom annotation CheckUuid (extends ): public void foo (@PathParam ("name") @CheckUuid String uuid) { ... } Is it possible to do validation using annotations on a stage when the method chosen, but not yet called? For example using PreProcessInterceptor?

  • Installing RestEasy documentation is not clear--does maven install resteasy?

    - by user798719
    3.1. Standalone Resteasy If you are using resteasy outside of JBoss AS 6, you will need to do a few manual steps to install and configure resteasy. RESTeasy is deployed as a WAR archive and thus depends on a Servlet container. We strongly suggest that you use Maven to build your WAR files as RESTEasy is split into a bunch of different modules. You can see an example Maven project in one of the examples in the examples/ directory Also, when you download RESTeasy and unzip it you will see a lib/ directory that contains the libraries needed by resteasy. Copy these into your /WEB-INF/lib directory. Place your JAX-RS annotated class resources and providers within one or more jars within /WEB-INF/lib or your raw class files within /WEB-INF/classes. Hi, is my confusion justified? I am using JBoss 5 unfortunately. Do I need to download RESTeasy and unzip it IF I am using Maven, as the documentation recommends? Maven grabs all the dependencies that are needed to build a project, including the RESTEasy fraemwork, right? So why the contradiction here? Wish that the documentation would anticipate common questions and be written more clearly.

  • How optimize code with introspection + heavy alloc on iPhone

    - by mamcx
    I have a problem. I try to display a UITable that could have 2000-20000 records (typicall numbers.) I have a SQLite database similar to the Apple contacts application. I do all the tricks I know to get a smoth scroll, but I have a problem. I load the data in 50 recods blocks. Then, when the user scroll, request next 50 until finish the list. However, load that 50 records cause a notable "pause" in loading and scrolling. Everything else works fine. I cache the data, have opaque cells, draw it by code, etc... I swap the code loading the same data in dicts and have a performance boost but wonder if I could keep my object oriented aproach and improve the actual code. This is the code I think have the performance problem: -(NSArray *) loadAndFill: (NSString *)sql theClass: (Class)cls { [self openDb]; NSMutableArray *list = [NSMutableArray array]; NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; DbObject *ds; Class myClass = NSClassFromString([DbObject getTableName:cls]); FMResultSet *rs = [self load:sql]; while ([rs next]) { ds = [[myClass alloc] init]; NSDictionary *props = [ds properties]; NSString *fieldType = nil; id fieldValue; for (NSString *fieldName in [props allKeys]) { fieldType = [props objectForKey: fieldName]; fieldValue = [self ValueForField:rs Name:fieldName Type:fieldType]; [ds setValue:fieldValue forKey:fieldName]; } [list addObject :ds]; [ds release]; } [rs close]; [pool drain]; return list; } And I think the main culprit is: -(id) ValueForField: (FMResultSet *)rs Name:(NSString *)fieldName Type:(NSString *)fieldType { id fieldValue = nil; if ([fieldType isEqualToString:@"i"] || // int [fieldType isEqualToString:@"I"] || // unsigned int [fieldType isEqualToString:@"s"] || // short [fieldType isEqualToString:@"S"] || // unsigned short [fieldType isEqualToString:@"f"] || // float [fieldType isEqualToString:@"d"] ) // double { fieldValue = [NSNumber numberWithInt: [rs longForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"B"]) // bool or _Bool { fieldValue = [NSNumber numberWithBool: [rs boolForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"l"] || // long [fieldType isEqualToString:@"L"] || // usigned long [fieldType isEqualToString:@"q"] || // long long [fieldType isEqualToString:@"Q"] ) // unsigned long long { fieldValue = [NSNumber numberWithLong: [rs longForColumn:fieldName]]; } else if ([fieldType isEqualToString:@"c"] || // char [fieldType isEqualToString:@"C"] ) // unsigned char { fieldValue = [rs stringForColumn:fieldName]; //Is really a boolean? if ([fieldValue isEqualToString:@"0"] || [fieldValue isEqualToString:@"1"]) { fieldValue = [NSNumber numberWithInt: [fieldValue intValue]]; } } else if ([fieldType hasPrefix:@"@"] ) // Object { NSString *className = [fieldType substringWithRange:NSMakeRange(2, [fieldType length]-3)]; if ([className isEqualToString:@"NSString"]) { fieldValue = [rs stringForColumn:fieldName]; } else if ([className isEqualToString:@"NSDate"]) { NSDateFormatter* dateFormatter = [[NSDateFormatter alloc] init]; [dateFormatter setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss"]; NSString *theDate = [rs stringForColumn:fieldName]; if (theDate) { fieldValue = [dateFormatter dateFromString: theDate]; } else { fieldValue = nil; } [dateFormatter release]; } else if ([className isEqualToString:@"NSInteger"]) { fieldValue = [NSNumber numberWithInt: [rs intForColumn :fieldName]]; } else if ([className isEqualToString:@"NSDecimalNumber"]) { fieldValue = [rs stringForColumn :fieldName]; if (fieldValue) { fieldValue = [NSDecimalNumber decimalNumberWithString:[rs stringForColumn :fieldName]]; } } else if ([className isEqualToString:@"NSNumber"]) { fieldValue = [NSNumber numberWithDouble: [rs doubleForColumn:fieldName]]; } else { //Is a relationship one-to-one? if (![fieldType hasPrefix:@"NS"]) { id rel = class_createInstance(NSClassFromString(className), sizeof(unsigned)); Class theClass = [rel class]; if ([rel isKindOfClass:[DbObject class]]) { fieldValue = [rel init]; //Load the record... NSInteger Id = [rs intForColumn:[theClass relationName]]; if (Id>0) { [fieldValue release]; Db *db = [Db currentDb]; fieldValue = [db loadById: theClass theId:Id]; } } } else { NSString *error = [NSString stringWithFormat:@"Err Can't get value for field %@ of type %@", fieldName, fieldType]; NSLog(error); NSException *e = [NSException exceptionWithName:@"DBError" reason:error userInfo:nil]; @throw e; } } } return fieldValue; }
