JBoss - how to take thread dumps


Following are the different options in JBoss to take the thread dump.

1. Using JBoss jmx-console :  Got to http://localhost:8080/jmx-console and search for the mbean "serverInfo" and click on that link. Click the invoke mbean operation under listThreaddump() method. This will give you the current snapshot of threads which are running in your JBoss jvm.

2. By using twiddle :  In the commnad promt go to <JBOSS-HOME>/bin and run the command twiddle.bat invoke "jboss.system:type=ServerInfo" listThreadDump > threadDump.html and you could find the threadDump.html with the JBoss thread dump.

3. Using "Interrupt" signal : Use kill -3 <process-id> to generate thread dump. You will find the thread dumps in server logs.

ATG - more about Forms and Form Handlers

An ATG form is defined by the dsp:form tag, which typically encloses DSP tags that specify form elements, such as dsp:input that provide direct access to Nucleus component properties. Find below a sample dsp:form tag.    <dsp:form action="/testPages/showPersonProperties.jsp" method="post" target="_top">      <p>Name: <dsp:input bean="/samples/Person.name" type="text"/>      <p>Age: <dsp:input bean="/samples/Person.age" type="text" value="30"/>      <p><dsp:input type="submit" bean="/samples/Person.submit"/> value="Click to submit"/>    </dsp:form>   When the user submits the form, the /samples/Person.name property is set to the value entered in the input field.Unlike standard HTML, which requires the name attribute for most input tags; the name attribute is optional for DSP form element tags.

ATG Search - high level overview of product-catalog-output-config.xml and XHTMLs

The definition file format begins with a top-level item element that specifies the repository and item descriptor to use, and then lists the properties of that item type to include. The top-level item element has the is-document attribute set to true. This attribute specifies that an XHTML document should be generated for each item of that type (in this case, each user item). Property values that come from standard JavaBean properties of the RepositoryItem object (rather than dynamic bean properties) are specified using a dollar-sign ($) prefix. The item element has an is-multi attribute for specifying multi-value properties. If a property is an Array, Collection or Map  you should set this attribute to true. Eeach ATG Search document is uniquely identified by a URL (typically the path name of the file on the file system). In the XHTML documents that the ATG platform generates from repository items, meta properties are represented by meta tags in the head of the document, whi...
