  • why am I stuck on "Initiating update" when deploying to google

    - by michelle
    I've have not had any trouble deploying through eclipse until now. I'm guessing it might have to do with all the stuff I've added today a folder of .pdf and .tex files (in war/web-inf directory) a bit of JDO stuff and a servlet that reads the files in the directory and indexes them into the JDO Is there any way to find out what exactly is the problem? I currently get stuck at "Initiating update" and the stack trace say "ConnectionReset" Any helkp of imput will be appreciated, I really need to deploy this today, thanks! here's the deploy trace: Unable to update: java.net.SocketException: Connection reset at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection$6.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.net.www.protocol.http.HttpURLConnection.getChainedException(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at java.net.HttpURLConnection.getResponseCode(Unknown Source) at com.google.appengine.tools.admin.ServerConnection.getAuthCookie(ServerConnection.java:315) at com.google.appengine.tools.admin.ServerConnection.authenticate(ServerConnection.java:219) at com.google.appengine.tools.admin.ServerConnection.send(ServerConnection.java:145) at com.google.appengine.tools.admin.ServerConnection.post(ServerConnection.java:81) at com.google.appengine.tools.admin.AppVersionUpload.send(AppVersionUpload.java:427) at com.google.appengine.tools.admin.AppVersionUpload.beginTransaction(AppVersionUpload.java:241) at com.google.appengine.tools.admin.AppVersionUpload.doUpload(AppVersionUpload.java:98) at com.google.appengine.tools.admin.AppAdminImpl.update(AppAdminImpl.java:56) at com.google.appengine.eclipse.core.proxy.AppEngineBridgeImpl.deploy(AppEngineBridgeImpl.java:271) at com.google.appengine.eclipse.core.deploy.DeployProjectJob.runInWorkspace(DeployProjectJob.java:148) at org.eclipse.core.internal.resources.InternalWorkspaceJob.run(InternalWorkspaceJob.java:38) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55) Caused by: java.net.SocketException: Connection reset at java.net.SocketInputStream.read(Unknown Source) at java.io.BufferedInputStream.fill(Unknown Source) at java.io.BufferedInputStream.read1(Unknown Source) at java.io.BufferedInputStream.read(Unknown Source) at sun.net.www.http.HttpClient.parseHTTPHeader(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.http.HttpClient.parseHTTP(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(Unknown Source) at sun.net.www.protocol.http.HttpURLConnection.getHeaderFieldKey(Unknown Source) at com.google.appengine.tools.util.ClientCookieManager.readCookies(ClientCookieManager.java:123) at com.google.appengine.tools.admin.ServerConnection.connect(ServerConnection.java:340) at com.google.appengine.tools.admin.ServerConnection.getAuthCookie(ServerConnection.java:314) ... 11 more

  • how to implement ws-security 1.1 in php5

    - by Sam Segers
    I'm trying to call a webservice with Soap in PHP5, for this, I need to use WS-Security 1.1. (In java and .NET this is all generated automatically.) Are there any frameworks available to generate the security headers easily in PHP? Or do I have to add the entire header myself ? Specifications of WS-Security 1.1: http://oasis-open.org/committees/download.php/16790/wss-1.1-spec-os-SOAPMessageSecurity.pdf

  • Which CMS for a mobile app? No HTML, just XML or JSON

    - by Sascha
    I am a newbie in content management systems. I would need a CMS that can transfer content by XML or JSON to a client. It is ok if the CMS can also manage HTML websites, but the priority is on the data transfer over a web service. Which is the best CMS to use here? I want to avoid spending endless hours learning all the big CMS systems just to find out that they don't support this feature or that it's badly integrated. Thanks.

  • Projects integration question

    - by qkrsppopcmpt
    Other team has one legacy system, which is data aggregators. It is implemented as web service using JAVA, SOAP,MTOM,Tomcat and Axis2. They have wsdl files defining functionalities such as search, retrieve data, upload, download. Our team has a new developed website which is developed using RoR with mySQL. It is sort of social networking. Users can register, add friends, upload images, videos. Also, they can search data. We are required to connect the two systems. One possible solution I think is - Adding components into our website. The component invoke services on the aggregators. - Synchronize website database to the aggregators. My doubts are: 1. How to add components in our websites? The components should use Java or Ruby or adapter from java to ruby. It is possible using ruby invoke web service. I think it should work since it is the point of web service. If so, can ruby call those services in wsdl directly? But how to deal with those different data structure? How to synchroinze our database to the aggregators. I think the best way is also through web service invocation such as upload. That means, we have to export the db records into xml files and then write some tools to upload. The web service project support MTOM. So, it is fine to upload huge data. Am I on the right record? Can anybody give me some hint. Thanks.

  • Installing sharepoint web service disabled when trying to install BizTalk adapter

    - by noesgard
    I have a MOSS Box, with Microsoft Office SharePoint Server 2007 SP2 (Danish server), .net 3.5 SP1 on a Server 2008 64 bit (where IIS is running 64 bit too). When I fire up the BizTalk installer and wants to select the SharePoint Web Service, this option is disabled/grayed out. Any ideas as how I can enable the option again? (It states that there are one or more prerequisites missing but I can't figure out which). I found some reference stating that I basically had to "toast" the MOSS box and install WSS 3, but that is NOT an option... Any suggestions? :o)

  • Frequent occurence of FULL GC.

    Hi, There is a frequent occurence of FULL GC in our system. We are using Java application running on Tomcat server. Our application is running using internal load balancer setup. We are seeing lot of Full GC's in the server logs due to which the application is hung and Proxy errors are occured. The Java parameter values we are using are: Webapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M Backapp wrapper: wrapper.java.additional.4=-Xms382M wrapper.java.additional.5=-Xmx1024M The error found in webapp wrapper logs: INFO | jvm 1 | 2010/11/26 09:33:19 | [PSYoungGen: 1398460K-140291K(1514624K)] 4623364K-3491394K(5009920K), 0.7285303 secs] [Times: user=1.42 sys=0.00, real=0.72 secs] INFO | jvm 1 | 2010/11/26 09:33:19 | 68539.126: [Full GC DEBUG | wrapperp | 2010/11/26 09:33:19 | send a packet PING : ping Tried to change the JVM values to increase the heap size.

  • JAX-WS MarshalException with custom JAX-B bindings: Unable to marshal type "java.lang.String" as an

    - by MoneyMark
    I seem to be having an issue with Jax-WS and Jax-b playing nicely together. I need to consume a web-service, which has a predefined WSDL. When executing the generated client I am receiving the following error: javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.SAXException2: unable to marshal type "java.lang.String" as an element because it is missing an @XmlRootElement annotation] This started occurring when I used an external custom binding file to map needlessly complex types to java.lang.string. Here is an excerpt from my binding file: <?xml version="1.0" encoding="UTF-8"?> <bindings xmlns="http://java.sun.com/xml/ns/jaxb" version="2.0" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"> <bindings schemaLocation="http://localhost:7777/GESOR/services/RegistryUpdatePort?wsdl#types?schema1" node="/xs:schema"> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='company_name']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address1']"> <property> <baseType name="java.lang.String" /> </property> </bindings> <bindings node="//xs:element[@name='StwrdCompany']//xs:complexType//xs:sequence//xs:element[@name='address2']"> <property> <baseType name="java.lang.String" /> </property> </bindings> ...more fields </bindings> </bindings> When executing wsimport against the provided WSDL, StwrdCompany is generated with the following variables declared: @XmlRootElement(name = "StwrdCompany") public class StwrdCompany { @XmlElementRef(name = "company_name", type = JAXBElement.class) protected String companyName; @XmlElementRef(name = "address1", type = JAXBElement.class) protected String address1; @XmlElementRef(name = "address2", type = JAXBElement.class) ... more fields ... getters/setters @XmlAccessorType(XmlAccessType.FIELD) @XmlType(name = "", propOrder = { "value" }) public static class CompanyName { @XmlValue protected String value; @XmlAttribute protected Boolean updateToNULL; /** * Gets the value of the value property. * * @return * possible object is * {@link String } * */ public String getValue() { return value; } /** * Sets the value of the value property. * * @param value * allowed object is * {@link String } * */ public void setValue(String value) { this.value = value; } /** * Gets the value of the updateToNULL property. * * @return * possible object is * {@link Boolean } * */ public boolean isUpdateToNULL() { if (updateToNULL == null) { return false; } else { return updateToNULL; } } /** * Sets the value of the updateToNULL property. * * @param value * allowed object is * {@link Boolean } * */ public void setUpdateToNULL(Boolean value) { this.updateToNULL = value; } ... more inner classes } } Finally, here is the associated snippet from the WSDL that seems to be causing such grief. <xs:element name="StwrdCompany"> <xs:complexType> <xs:sequence> <xs:element maxOccurs="1" minOccurs="0" name="company_name" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> <xs:element maxOccurs="1" minOccurs="0" name="address1" nillable="true"> <xs:complexType> <xs:simpleContent> <xs:extension base="xs:string"> <xs:attribute default="false" name="updateToNULL" type="xs:boolean"/> </xs:extension> </xs:simpleContent> </xs:complexType> </xs:element> ... more fields in the same format <xs:element maxOccurs="1" minOccurs="0" name="p_source_timestamp" nillable="false" type="xs:string"/> </xs:sequence> <xs:attribute name="company_xid" type="xs:string"/> </xs:complexType> </xs:element> The reason for the custom binding is so I can map user input from a pojo into the StwrdCompany object more easily, whether it be direct instantiation or through the use of Dozer for bean mapping. I was unable to successfully map between the objects without the custom binding. Finally, one other thing I tried was setting a globalBinding definition: <globalBindings generateValueClass="false"></globalBindings> This caused the server to through an argument mismatch exception since the Soap Message was using xs:string xml types instead of passing the defined complex types, so I abandoned that idea. Any insight into what is causing the MarshalException or how to go about solving the issue of calling the webservice and mapping these objects more easily, is greatly appreciated. I've been searching for days and I sadly think I am stumped.

  • Android: Strange out of memory issue

    - by Chrispix
    I am not sure where to start to explain this one. I have a list view with a couple image buttons on each row. When you click the list row, it launches a new activity. If you review some of my other posts, I have had to build my own tabs because of an issue w/ the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the sd card) the application returns from the activity back to the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. So here is the issue, the image preview on the list view is being done w/ the cursor & listadapter. This makes it pretty simple, but I am not sure how I can put a resized (i.e. smaller bit size not pixel) image as the src for the imgbutton on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. ** My question : is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? - this would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row w/ touch screen b/c of focus issue. (I can use roller ball). ** I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice if that is your suggestion. As soon as I disabled the image on the listview it worked fine again. FYI : This is how I was doing it : String[] from = new String[] { DBHelper.KEY_BUSINESSNAME, DBHelper.KEY_ADDRESS, DBHelper.KEY_CITY, DBHelper.KEY_GPSLONG, DBHelper.KEY_GPSLAT, DBHelper.KEY_IMAGEFILENAME + ""}; to = new int[] { R.id.businessname, R.id.address, R.id.city, R.id.gpslong, R.id.gpslat, R.id.imagefilename }; notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); Where R.id.imagefilename is a ButtonImage Here is my LogCat 01-25 05:05:49.877: ERROR/dalvikvm-heap(3896): 6291456-byte external allocation too

  • Calling Grep inside Java gives incorrect results while calling grep in shell gives correct results.

    - by futureelite7
    I've got a problem where calling grep from inside java gives incorrect results, as compared to the results from calling grep on the same file in the shell. My grep command (called both in Java and in bash. I escaped the slash in Java accordingly): /bin/grep -vP --regexp='^[0-9]+\t.*' /usr/local/apache-tomcat-6.0.18/work/Catalina/localhost/saccitic/237482319867147879_1271411421 Java Code: String filepath = "/path/to/file"; String options = "P"; String grepparams = "^[0-9]+\\t.*"; String greppath = "/bin/"; String[] localeArray = new String[] { "LANG=", "LC_COLLATE=C", "LC_CTYPE=UTF-8", "LC_MESSAGES=C", "LC_MONETARY=C", "LC_NUMERIC=C", "LC_TIME=C", "LC_ALL=" }; options = "v"+options; //Assign optional params if (options.contains("P")) { grepparams = "\'"+grepparams+"\'"; //Quote the regex expression if -P flag is used } else { options = "E"+options; //equivalent to calling egrep } proc = sysRuntime.exec(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath, localeArray); System.out.println(greppath+"/grep -"+options+" --regexp="+grepparams+" "+filepath); inStream = proc.getInputStream(); The command is supposed to match and discard strings like these: 85295371616 Hi Mr Lee, please be informed that... My input file is this: 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85291234783 a3283784428349247233834728482984723333 85219299222 The commands works when I call it from inside bash (Results below): 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85219299222 However, when I call grep again inside java, I get the entire file (Results below): 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85aaa234567 Hi Ms Chan, please be informed that... 85292vx5678 Hi Mrs Ng, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 8~!95371616 Hi Mr Lee, please be informed that... 85295371616 Hi Mr Lee, please be informed that... 852&^*&1616 Hi Mr Lee, please be informed that... 8529537Ax16 Hi Mr Lee, please be informed that... 85====ppq16 Hi Mr Lee, please be informed that... 85291234783 a3283784428349247233834728482984723333 85219299222 What could be the problem that will cause the grep called by Java to return incorrect results? I tried passing local information via the environment string array in runtime.exec, but nothing seems to change. Am I passing in the locale information incorrectly, or is the problem something else entirely?

  • Ho to make Histogram Normalize and Equalize in java using JAI library?

    - by Jay
    I m making App in java using Swing component and JAI library. I make histogram of black and white or gray scale image.Is this method of making histogram correct? iif it is correct then how can i do normalization and Equalization of histogram in my App in java using JAI library?my code is below. in my code i make BufferedImage object and then make and plot histogram of that image . enter code here import java.awt.Color; import java.awt.Graphics; import java.awt.image.BufferedImage; import java.io.IOException; import javax.media.jai.JAI; import javax.media.jai.PlanarImage; import javax.swing.*; public class FinalHistogram extends JPanel { static int[] bins = new int[256]; static int[] newBins = new int[256]; static int x1 = 0, y1 = 0; static PlanarImage image = JAI.create("fileload", "alp_finger.tiff"); static BufferedImage bi = image.getAsBufferedImage(); FinalHistogram(int[] pbins) { for (int i = 0; i < 256; i++) { bins[i] = pbins[i]; newBins[i] = 0; } repaint(); } @Override protected void paintComponent(Graphics g) { for (int i = 0; i < 256; i++) { g.drawLine(150 + i, 300, 150 + i, 300 - (bins[i] / 300)); if (i == 0 || i == 255) { String sr = new Integer((i)).toString(); g.drawString(sr, 150 + i, 305); } System.out.println("bin[" + i + "]===" + bins[i]); } } public static void main(String[] args) throws IOException { int[] sbins = new int[256]; int pixel = 0; int k = 0; for (int x = 0; x < bi.getWidth(); x++) { for (int y = 0; y < bi.getHeight(); y++) { pixel = bi.getRaster().getSample(x, y, 0); k = (int) (pixel / 256); sbins[k]++; //pixel = bi.getRGB(x, y) & 0x000000ff; //k=pixel; //int[] pixels = m_image.getRGB(0, 0, m_image.getWidth(), m_image.getHeight(), null, 0, m_image.getWidth()); //short currentValue = 0; //int red,green,blue; //for(int i = 0; i<pixels.length; i++){ //red = (pixels[i] >> 16) & 0x000000FF; //green = (pixels[i] >>8 ) & 0x000000FF; //blue = pixels[i] & 0x000000FF; //currentValue = (short)((red + green + blue) / 3); //Current value gives the average //Disregard the alpha //assert(currentValue >= 0 && currentValue <= 255); //Something is awfully wrong if this goes off... //m_histogramArray[currentValue] += 1; //Increment the specific value of the array //} } } JTabbedPane jtp = new JTabbedPane(); jtp.addTab("Histogram", new JScrollPane(new FinalHistogram(sbins))); JFrame frame = new JFrame(); frame.setSize(500, 500); frame.add(new JScrollPane(jtp)); frame.setVisible(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } }

  • ListView slow performance

    I've created a list of recipes using Listview/customcursoradapter. A custom layout includes a photo for the recipe , Now I've some problems with the performance of viewing and scrolling the Listview although it has only 10 records (Target is 150). sometimes i get this error java.lang.OutOfMemoryError: bitmap size exceeds VM budget , I've tried to implement the Async task but i failed to do it. Is there any way i can overcome this problem? Your help is highly appreciated !! Here is my GetView method public View getView(int position, View convertView, ViewGroup parent) { View row = super.getView(position, convertView, parent); Cursor cursbbn = getCursor(); if (row == null) { LayoutInflater inflater = (LayoutInflater) localContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

  • Why does this Java code not utilize all CPU cores?

    The attached simple Java code should load all available cpu core when starting it with the right parameters. So for instance, you start it with java VMTest 8 int 0 and it will start 8 threads that do nothing else than looping and adding 2 to an integer. Something that runs in registers and not even allocates new memory. The problem we are facing now is, that we do not get a 24 core machine loaded (AMD 2 sockets with 12 cores each), when running this simple program (with 24 threads of course). Similar things happen with 2 programs each 12 threads or smaller machines. So our suspicion is that the JVM (Sun JDK 6u20 on Linux x64) does not scale well. Did anyone see similar things or has the ability to run it and report whether or not it runs well on his/her machine (= 8 cores only please)? Ideas? I tried that on Amazon EC2 with 8 cores too, but the virtual machine seems to run different from a real box, so the loading behaves totally strange. package com.test; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; import java.util.concurrent.Future; import java.util.concurrent.TimeUnit; public class VMTest { public class IntTask implements Runnable { @Override public void run() { int i = 0; while (true) { i = i + 2; } } } public class StringTask implements Runnable { @Override public void run() { int i = 0; String s; while (true) { i++; s = "s" + Integer.valueOf(i); } } } public class ArrayTask implements Runnable { private final int size; public ArrayTask(int size) { this.size = size; } @Override public void run() { int i = 0; String[] s; while (true) { i++; s = new String[size]; } } } public void doIt(String[] args) throws InterruptedException { final String command = args[1].trim(); ExecutorService executor = Executors.newFixedThreadPool(Integer.valueOf(args[0])); for (int i = 0; i < Integer.valueOf(args[0]); i++) { Runnable runnable = null; if (command.equalsIgnoreCase("int")) { runnable = new IntTask(); } else if (command.equalsIgnoreCase("string")) { runnable = new StringTask(); } Future<?> submit = executor.submit(runnable); } executor.awaitTermination(1, TimeUnit.HOURS); } public static void main(String[] args) throws InterruptedException { if (args.length < 3) { System.err.println("Usage: VMTest threadCount taskDef size"); System.err.println("threadCount: Number 1..n"); System.err.println("taskDef: int string array"); System.err.println("size: size of memory allocation for array, "); System.exit(-1); } new VMTest().doIt(args); } }

  • Is it normal for Java /Tomcat to keep checking for java_pid<nnnn>.hprof?

    - by Chris
    I was monitoring my JVM running Apache Tomcat 6, running on Windows, and I noticed that every 3 seconds or so the JVM process (C:\Tomcat\bin\tomcat6.exe) is polling to see whether or not C:\Tomcatcat\java_pid3748.hprof exists, where 3748 is the Windows process ID. I haven't seen write to the hprof file, just test for existence. (I'm using Sysinternals Process Monitor (procmon.exe) for this monitoring. In procmon the polling shows up as a QueryDirectory operation, which always returns Result "NO SUCH FILE".) Is this normal, or is this a potential red flag? I gather that these hprof files are generated, perhaps among other times, when you enable the -XX:+HeapDumpOnOutOfMemoryError Java flag. I haven't enabled it myself, though I guess it could be enabled somehow in the Tomcat startup scripts.

  • Where to set java heap options (e.g. -Xmx) for Tomcat 6 under Ubuntu 9.04?

    - by Chris
    I'm running Tomcat using the tomcat6 package from Ubuntu 9.04, which makes a daemon out of Tomcat using jsvc. I'd like to know the proper way to set Java heap options like -Xmx for Tomcat. I'd like to put the configuration wherever is most stylistically correct, and wherever is least likely to be overwritten by Ubuntu package updates. The options I see right now: Hard-code them somewhere in /etc/init.d/tomcat6. Hard-code them somewhere in /usr/share/tomcat6/bin/catalina.sh. Create a line in /usr/share/tomcat6/bin/startup.sh to set CATALINA_OPTS to have the desired flags, and then export CATALINA_OPTS as an environment variable. (This looks like it will get picked up by catalina.sh.) The last option sounds like the best one, and it's advocated (without explanation of why) at http://serverfault.com/questions/121038/increasing-javas-heapspace-in-tomcat-startup-script. But I wanted to get a second opinion. Anyone want to confirm that there isn't a better way?
