[JBoss-user] Cocoon war dir hot-redeploy causes JBoss Shutdown
Hi, all. My company has found a bug, which I've since entered at SourceForge. Thought I'd copy/paste the details here to give it some visibility and see if others have seen the same problem. Thanks! Bug: 840496 https://sourceforge.net/tracker/?func=detail&atid=376685&aid=840496&group_id=22866 I've discovered a problem that only happens with jboss 3.0 + tomcat + cocoon 2.0 + expanded war directory, relating to hot-redeploy. Basically, if you have a cocoon.war/ *directory* web application, and touch it's web.xml file, JBoss shuts down! Here are the steps to re-create: 1) Download a completely fresh jboss-3.0.7_tomcat-4.1.24 from sourceforge. 2) Download a completely fresh cocoon-2.0.4 (vm14) from apache. 3) Dropped cocoon.war in jboss' deploy directory. 4) Started up jboss. 5) Hit the cocoon servlet (got a sitemap error but didn't care) 6) "touch" cocoon.war. 7) NO REDEPLOY PROBLEM 8) Hit the cocoon servlet (got same sitemap error but still didn't care - at least could still hit it). 9) Stop jboss. 10) Delete the db, tmp and log dirs to be completely clean distro again. 11) Explode the cocoon.war file into cocoon.war/ *DIRECTORY INSTEAD*. 12) Start up jboss. 13) Hit the cocoon servlet (sitemap error; still don't care) 14) "touch" cocoon.war/WEB-INF/web.xml 15) *** REDEPLOY PROBLEM: jboss shuts down!! *** JBoss/Jetty does not do this. JBoss 3.2.x does not do this. A JBoss/Tomcat webapp without Cocoon does not do this. JBoss/Tomcat with a Cocoon war *file* does not do this. It has to be JBoss 3.0/Tomcat with a Cocoon 2.0 war *directory*, and you touch it's web.xml file to cause a redeploy. I have tested it on many different combinations, and here is the breakdown: 1) jboss-3.0.7_tomcat-4.1.24 + cocoon-2.0.4 - FAILED 2) jboss-3.0.8_tomcat-4.1.24 + cocoon-2.0.4 - FAILED 3) jboss-3.0.8_tomcat-4.1.27 + cocoon-2.0.4 - FAILED 4) jboss-3.0.8_tomcat-4.1.29 + cocoon-2.0.4 - FAILED 5) jboss-3.2.2 (tomcat_4.1.27) + cocoon-2.0.4 - PASSED 6) jboss-3.0.8_tomcat-4.1.24 + cocoon-2.1.2 - PASSED, though 500 errors Something was fixed in JBoss 3.2.2 / Tomcat that fixed this problem. Does anyone have any idea what this was? Unfortunately, we cannot upgrade to JBoss 3.2.2 right now. If the fix is known, can it be backported back to 3.0? A jboss-3.0.9_tomcat-4.1.29 with the backported fix would be awesome and greatly appreciated! BTW, with JBoss 3.2.2, it looks like the shutdown was intercepted; here's a line from the console: 22:43:58,980 INFO [STDOUT] Mon Nov 03 22:43:58 EST 2003 SHUTDOWN : System.exit() was not called When I see that line with 3.2.2, the redeploy finishes and JBoss does not shutdown. Maybe find where that log is done and see what can be similarly done in 3.0.x to intercept the shutdown? Last bit of info: This is using Sun JDK 1.4.1 and 1.4.2. It is recreateable on Windows; not sure about Linux and MacOSX. Thanks! David PS: Scott, I apologize if it was bad for me to assign it to you. I did it because I know you've been the one in the past that has dealt with web-tier integration into jboss, so I thought you'd be interested in this one. --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

Re: [JBoss-user] Re: Jetty vs Tomcat
So if I wanted ALL jsp pages in my webapp to be compiled when it is deployed would I change this part of the webdefault.xml file: jsp org.apache.jasper.servlet.JspServlet 0 to this?: jsp org.apache.jasper.servlet.JspServlet 1 I tested this by creating a jsp page that does not compile and reploying it.

Re: [JBoss-user] Problem with SQL query for MySQL
Hello,
I have exactly the same problem as Rafal, but with the following JBoss-generated query:
"CREATE TABLE user (user_id INTEGER NOT NULL,login VARCHAR(250) BINARY,
password_ VARCHAR(250) BINARY, first_name VARCHAR(250) BINARY, last_name VARCHAR(250) BINARY,
gender VARCHAR(250) BINARY, email VARCHAR(250) BINARY, school_id INTEGER,
CONSTRAINT pk_user PRIMARY KEY (user_id))"
I downloaded the latest JBoss 3.2.3RC1, released today but unfortunately with the same
result..
Were your modification taken in account in this release or is it a different problem?
Thanks,
Paul

Re: [JBoss-user] Clueless on transactions
Again, the key point is that the cost of a jta tx is small. RequiresNew introduces a new tx and new lock that is isolated from the encompassing session tx. If used with an entity with commit option A caching or a custom caching policy like option D(option A + timeout), then there is no jdbc tx to access the database. The read-only tags have the same effect without introducing a new jta tx. -- Scott Stark Chief Technology Officer JBoss Group, LLC Brian McSweeney wrote: Thanks Scott, All makes sense except why does RequiresNew minimize the extent of the transaction lock. If anything I would have thought RequiresNew only decreases performance because it creates a new transaction and can't use an existing one if available. Thanks very much for all your help.

RE: [JBoss-user] Clueless on transactions
Thanks Scott, All makes sense except why does RequiresNew minimize the extent of the transaction lock. If anything I would have thought RequiresNew only decreases performance because it creates a new transaction and can't use an existing one if available. Thanks very much for all your help.

Re: [JBoss-user] Read only CMR Collections?
What about using filters to begin/commit transactions? Neal Sanche wrote: Hi Alexey, Oh, I am definitely using the servlet container in the same VM, and although it's probably a really bad idea, I've been using Local objects in my web view layer instead of constantly making value objects all the time. This works fine until CMR collections are involved. Beginning a transaction is really not a good thing in the web view layer. Even in the web controller/model layer I've decided not to use transactions, instead calling session beans to handle any CMR accesses. Oh well, I guess the spec has us all hogtied. I'll have to look into what value objects can provide me with regard to CMR collections, then. -Neal On November 10, 2003 03:03 pm, Alexey Loubyansky wrote: First, it is the spec requirement.

[JBoss-user] relation VS value-object
Greetings, I would like to know what diferences (advantages/disadvantages) exist between using a relation and using a value-object? I recently made this interface method to represent a relation but I also inserted an optional value-object method. /** * @ejb.interface-method * view-type="local" * @ejb.relation * name="service_TO_primitive" * role-name="service_CALLS_primitive" * cascade-delete="no" * target-ejb="Primitive" * target-role-name="primitive_IS_CALLED_BY_service" * target-cascade-delete="no" * target-multiple="no" * @ejb.value-object * aggregate="pt.ptinovacao.nginpro.uif.ejb.access.PrimitiveValue" * aggregate-name="primitive" * relation="external" * @jboss.relation * related-pk-field="primitiveId" * fk-column="primitive_id" */ public abstract PrimitiveLocal getPrimitive(); public abstract void setPrimitive(PrimitiveLocal primitive); The only thing I can manage here is that in a relation I may have a delete cascade and in a value-object I'm unable to define it. So, can any of you briefly show me what uses are reasonable to use with one method or the other? NOTE: the performance issue is very important to me! thanks, Pedro Salazar. -- -PS --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

Re: [JBoss-user] Clueless on transactions
I'm not sure... But once I put an @ejb.transaction="Required" on all setXXX methods of my Entity bean. This made sure that only setters are in the transaction. When looking up values there will we no transaction used... Am I right about this?

A web page initiates a request that spans a workflow through any number of ejbs/jca resources and the ejb contract does say there should only be one transaction active in a given ejb. You can control the scope of the transactional lock using transactional tags like RequiresNew and read-only fields, but you have to draw out the workflows to see where the web pages are going to be conflicting. If there is no shared data there is no lock contention. We cover this is the advanced training. Brian McSweeney wrote: > Hi Scott, > Thanks for the help.

[JBoss-user] How to limit the the number of records (Objects) a select returns
Title: Message I am using jboss-3.2.2RC1_tomcat-4.1.24 backed by a MySql database. In the MySql SQL I can limmit the number of rows retrieved by a SELECT steatment by a LIMIT clause How can I limit the number of objects in a collection (of a findAll for example) when possebly huge amounts of objects would match the selection. And / or how can I find out in advance how much records would match the selection In the jbosscmp-jdbc_3_0.dtd I found a section which declarese the syntaxt of an element in the jbosscmp-jdbc XML deployment file but as I am anything else as an expert DTD reader It does not tell me how and when that can (if at all) be used. The example mentions the LIMIT steatment. Here is the piece extracted from the jbosscmp-jdbc_3_0.dtd Could anyone give me a hint on how I could solve this problem. Thanks a lot.
